CONCURRENT CANADIAN PROSPECTUS OFFERING

On December 21, 2011, we filed a prospectus withIn October 2018, the securities regulatory authorities in each province of Canada other than the Province of Québec in connection with our initial public offering in Canada and our application to list our shares of common stock on the Toronto Stock Exchange. As part of the filing process, we were required to prepare and file with Canadian securities regulators a technical report on each of our material properties prepared in accordance with National Instrument 43-101, or NI 43-101, which is an instrument developed by the Canadian Securities Administrators and administered by the provincial securities commissions that governs how issuers in Canada disclose scientific and technical information about their mineral projects to the public. United States reporting requirements for disclosure of mineral properties are governed by Industry Guide 7 promulgated by the U.S. Securities and Exchange Commission or(the "SEC") adopted amendments to its current disclosure rules to modernize the SEC. NI 43-101 andmineral property disclosure requirements for mining registrants. The amendments include the adoption of a new subpart 1300 of Regulation S-K, which will govern disclosure for mining registrants (the "SEC Mining Modernization Rules"). The SEC Mining Modernization Rules replace the historical property disclosure requirements for mining registrants that were included in the SEC's Industry Guide 7 standards are substantially different.

TheOur Company

Sunshine Silver Mines Corporation is        We are a U.S.-based precious metals explorationproduction, development and developmentexploration company with the objective of becoming a premier silver producer. The Company isWe are currently focused on the advancementproduction and continued development of its two principal projects:the Cerro Los Gatos Mine and the further exploration and development of the Los Gatos District:

    The Cerro Los Gatos Mine, located within the Los Gatos District, Chihuahua, Mexico, consists of a 2,500 tpd polymetallic mine and processing facility that commenced production on September 1, 2019. For the year ended December 31, 2019, at the Cerro Los Gatos Mine, 357,342 tonnes were mined and 269,853 tonnes were processed at average grades of 229 g/t silver, 0.52 g/t gold, 1.97% lead and 3.03% zinc, with metallurgical recovery of 82.1% silver, 63.5% gold, 83.4% lead and 72.3% zinc. For the six-months ended June 30, 2020, at the Cerro Los Gatos Mine, 288,882 tonnes were mined and 298,331 tonnes were processed at average grades of 195 g/t silver, 0.44 g/t gold, 2.22% lead and 3.41% zinc, with metallurgical recovery of 82.2% silver, 61.8% gold, 85.1% lead and 72.4% zinc. The Los Gatos Technical Report, which has an effective date of July 1, 2020, estimates that the deposit contains 9.6 million diluted tonnes of proven and probable mineral reserves (or 5.0 million diluted tonnes of proven and probable mineral reserves on a 51.5% basis), with 6.4 million diluted tonnes of proven mineral reserves (or 3.3 million diluted tonnes of proven mineral reserves on a 51.5% basis) and 3.3 million diluted tonnes of probable mineral reserves (or 1.7 million diluted tonnes of probable mineral reserves on a 51.5% basis). Average proven and probable mineral reserve grades are 306 g/t silver, 0.35 g/t gold, 2.76% lead and 5.65% zinc.

    The Los Gatos DistrictThe Sunshine Mine, located in Idaho, is one of the highest-grade known primary-silver deposits worldwide, with an estimated 2,880,312 tonnes of mineralized material at an average silver grade of 781.7 grams/Tonne (inclusive of expected mining dilution). In December 2012, an independent preliminary economic assessment was completed on the Sunshine Mine, indicating a robust silver project.

The Los Gatos Project, located in Chihuahua, Mexico, is comprised of a 149,083 hectare land position, constituting a new mining region. The Los Gatos Project consists of three identified silver discoveries, the Cerro Los Gatos zone, the Esther zone and the Amapola zone, and 10 other priority targets. In December 2012, an independent technical report completed on the Company’s primary zones of focus at the Los Gatos Project estimated that the Cerro Los Gatos deposit contains 5,270,000 tonnes of mineralized material at an average silver grade of 179 grams/Tonne, 2.0% lead and 4.2% zinc; the Esther deposit contains 620,000 tonnes of mineralized material at an average silver grade of 113 grams/Tonne, 0.6% lead and 1.7% zinc; and the Amapola deposit contains 480,000 tonnes of mineralized material at an average silver grade of 101 grams/Tonne, 0.1% lead and 0.2% zinc (estimates are undiluted in-situ).

In total, as of the date of this prospectus, the Company owns or controls a portfolio of 23 exploration properties in the United States and Mexico covering an area of approximately 576,336 hectares.

Principal Projects

LOGO

Sunshine Mine

The Sunshine Mine, acquired by the Company in the first half of 2010, is located within the mining-friendly Coeur d’Alene Mining District in Idaho. As a past-producing mine, the Sunshine Mine is estimated to have produced over 365 million ounces of silver from 1904 to 2008. In 1990, the last year the Sunshine Mine operated at full capacity, silver production from the Sunshine Mine was approximately 5.4 million ounces. In 2008, Sterling Mining Company, or Sterling, the prior owner of the Sunshine Mine, ceased production and in early 2009 went into bankruptcy due to, we believe, among other factors, falling silver prices and inadequate capital.

The Sunshine Mine has significant existing on-site infrastructure, including an operational primary shaft, which is being modernized and upgraded, and a secondary shaft, which is being refurbished. The Company’s consolidated land position at the Sunshine Mine property currently consists of approximately 3,901 hectares. The property has an abundant water supply, is connected to the electricity grid and is accessible by paved roads. The Company has all environmental permits in place to begin surface and sub-surface operations on the property. Construction permits will be applied for as needed as the Company begins construction activities.

The underground workings at the Sunshine Mine consist of multiple levels developed off the primary shaft, extending from the surface to a depth of over 1,825 meters.

LOGO

Though a significant historical producing mine, the Company believes that the Sunshine Mine property remains highly prospective. As a result, the Company is undertaking significant exploration and re-development of the property. Based on ongoing exploration activities which began in 2011, the Company has discovered the new “10” vein and extensions of the Sunshine Vein and the Yankee Boy Split Vein. The Company continues to drill in key target areas.

An independent technical report, prepared by Tetra Tech, estimated 2,880,312 tonnes of mineralized material at an average silver grade of 781.7 grams/Tonne (inclusive of expected mining dilution) at the Sunshine Mine property.

Sunshine Silver’s objectives at the Sunshine Mine property are to:

continue to define additional mineralized material through expanded surface and underground exploration;

complete the upgrading of the Jewell shaft;

upgrade the Silver Summit shaft to provide a secondary access to certain underground levels;

complete a feasibility study if Sunshine Silver deems it necessary or appropriate to do so;

develop sufficient stope access to return the mine to production;

commence mining in the upper portions of the mine;

complete the construction of a new modern ore processing facility that will produce silver-bearing concentrates; and

upgrade other existing infrastructure and re-establish access to developed portions of the resource.

The Sunshine Mine property will require significant time and capital investment before the property returns to production. The Company anticipates that it will continue to incur operating costs without realizing any revenues at the Sunshine Mine until at least late 2014. See “Business—The Sunshine Mine Property” beginning on page 70.

Los Gatos Project

The Los Gatos Project is located approximately 120 kilometers south of the state capital of Chihuahua City in Northern Mexico and to date,is comprised of a 103,087-hectare land position, constituting a new mining district. The Los Gatos District consists of 14 mineralized zones, which include three identified silver discoveries, silver-lead-zinc deposits that contain mineral resources—the Cerro Los Gatos zone,Mine, the Esther zonedeposit and the Amapola zone,deposit—as well as 11 additional high-priority targets defined by high-grade drill intersections and 10 other priority targets with over 100150 kilometers of outcropping quartz and

      calcite veins. The area is characterized by a predominant silver-lead-zinc epithermal mineralization. On September 1, 2019, the LGJV commenced production at the Cerro Los Gatos Mine. A core component of the LGJV's business plan is to explore the highly prospective, underexplored Los Gatos District with the objective of identifying additional mineral deposits that can be mined and processed, possibly utilizing the Cerro Los Gatos Mine plant infrastructure.

In 2008, the Companywe negotiated surface access rights with local ranch owners and obtained the necessary environmental permits for drilling.drilling and road construction. Through 2015, we purchased all the surface lands required for the Cerro Los Gatos Mine development. Environmental baseline data collection began in May 2010 and was completed in 2016 and approved in 2017 to prepare for the development of future environmental studies required for the Cerro Los Gatos Project. Mine. In 2014, we partnered with Dowa Metals and Mining Co., Ltd. ("Dowa"), which manufactures and distributes metals products and owns Japan's largest zinc refinery, to finance and develop the Cerro Los Gatos Mine and to pursue exploration in the Los Gatos District. We and Dowa formed a Mexico-incorporated co-owned operating company, MPR, which owns certain surface and mineral rights associated with the Los Gatos District. In connection with the formation of the LGJV, we entered into the Unanimous Omnibus Partner Agreement with Dowa, MPR, OSJ, SSJ and Los Gatos Luxembourg S.a.r.l. on January 1, 2015 (as amended on April 10, 2017, June 30, 2017, March 10, 2018, May 20, 2019, April 29, 2020, May 25, 2020 and June 16, 2020, the "Unanimous Omnibus Partner Agreement"), which governs our and Dowa's respective rights over the LGJV. We own approximately 51.5% of the LGJV, with Dowa owning the remainder. Despite owning the majority interest in the LGJV, we do not exercise control over the LGJV due to certain provisions contained in the Unanimous Omnibus Partner Agreement that currently require unanimous partner approval of all major operating decisions (such as certain approvals, the creation of security interests on property, any initial public offering of the joint venture, and litigation settlements). We intend to exercise our right to repurchase an 18.5% interest in the LGJV from Dowa, increasing our ownership to approximately 70.0%. Following this increase in our ownership interest in the LGJV, we will continue to not exercise control over the LGJV due to the provisions contained in the Unanimous Omnibus Partner Agreement that currently require unanimous partner approval of all major operating decisions.

Silver Industry Overview

Overview

Silver occursdeposits occur naturally in itstheir solid metallic state and isare commonly associated with deposits of gold, copper, lead and zinc. According to GFMS Limited, or GFMS, 2011 global supplyzinc as a secondary metal. Silver is a precious metal and demand totaled approximately 1.0 billion ouncesis widely used in the manufacturing of silver; approximately 73.2% of 2011 global supply camejewelry and silverware and as an investment. Silver is distinct from mine production.

Silver has strong supplyother precious metals in that it is both used in industrial applications and demand fundamentals with significant demand rooted in diverse sectors. The demand for silver is driven primarily by three uses: industrial, consumer and investment. According to GFMS, in 2011, industrial, consumer andas an investment represented 46.8%, 37.5% and 15.8% of silver demand, respectively.asset.

        

IndustrialSilver has a number of distinctive physical and chemical properties that make it an essential component in numerous industrial applications, including its strength, malleability, conductivity and ductility, its sensitivity to and high reflectance of light and its ability to endure extreme temperature ranges. These properties restrict its substitution in most applications, which include batteries, bearings and catalysts. GFMS data indicates that silver demand for industrial applications grew from 349.7 million ounces in 2001 to 486.5 million ounces in 2011, a 37.8% increase.

applications. Silver is one of the world's best conductorconductors of electricity among all metals and is used in virtually all electronics (includingelectronic components of common items such as solar panel photovoltaic cells, computers, televisions and cell phones). The most rapid growth in this sector is set to come from emerging markets, such as India and China, where rapid advances in living standards mean electronic goods have become increasingly affordable and desirable. In 2000, China accounted for just 8% of global industrial silver demand, against a 2011 contribution of 18%.phones.

Increases in emerging applications for silver (such as LCD technology and RFID technologies) are expected to continue to augment industrial demand. Emerging applications include utilizing silver’s reflectivity        Silver has also been used as a component in solar cells to produce “green” electricity, and utilizing silver’s antimicrobial properties in medical applications and in the preventionmedium of algae build-up in water purification systems. GFMS projects that global industrial demand for silver will increase to a new record high of 511.6 million ounces in 2014.

Consumer—Consumer use ofexchange since earliest recorded history. While it is no longer widely used as circulating currency, silver is primarilystill widely sought by investors for the fabricationits store of jewelry, silverware and coins, which rely on silver’s lustre, resistance to tarnishing and malleability. For these usesvalue attributes. In particular, silver is often alloyed to a small proportion of other metals, such as copper, to harden it. Sterling silver, for example, is 92.5% silver and 7.5% copper and has been the standard in many countries for silver jewelry since the 14th century. There has been a sharp uptick in Chinese consumer demand for silver, as GFMS data indicates that Chinese silverware fabrication rose by 10% in 2011 and Chinese jewelry demand continued to grow.

Investment—Investment demand for silver has increased significantly in the last 10 years, with the most significant investment demand coming from silver exchange traded funds, or ETFs, and bullion funds. Historically, the price of silver has shown at times a high correlation to the price of gold as a result of investment demand, and has been at times viewed as an attractive hedge against a decrease in the value of currency and inflation during times of economic uncertainty.

Demand

        The three principal drivers of silver demand are industrial applications, consumer use and investment. According to The Silver Institute's World Silver Survey 2020, demand for industrial applications is mainly driven by electrical and electronics uses, which accounted for 58.3% of industrial demand and 30.0% of total demand in 2019. Jewelry accounted for 20.3% of total demand and net physical investment represented 18.8% of total demand.

        Silver demand grew 0.4% in 2019 to a three-year high of 991.8 million ounces, from 988.3 million ounces the previous year, driven by a 12.3% surge in demand for net physical investment. This was offset by declines in silverware and other industrials. Silver remains difficult to substitute in many areas, and outside of a dip in 2009, demand for industrial applications has remained broadly flat since 2007. There was healthy photovoltaic demand in 2019, with support from structural changes in demand, such as vehicle electrification.

Supply

        Silver supply is primarily driven by mined silver production, which, according to The Silver Institute's World Silver Survey 2020, accounted for 81.7% of supply in 2019. Recycling largely accounted for the remainder of silver supply. Global silver supply increased 0.6% year-over-year in 2019 to 1,023 million ounces compared to 1,016.8 million ounces in 2018.

        Mine silver output in 2019 declined for the fourth consecutive year, falling 1.3% to 836.5 million ounces from 847.8 million ounces in 2018. These recent production declines follow 13 consecutive years of growth. The decrease in silver supply was largely driven by lower grades at primary silver mines, lower silver production from copper mines and losses from production disruptions. In Peru, Compañía de Minas Buenaventura's Uchucchacua Mine saw silver production decrease from a 27% decline in grades and experienced a 21-day strike; Hochschild Mining's Arcata Mine was placed into care and maintenance early in the year; and declining silver grades were a factor at large primary copper mines. In Mexico, Fresnillo plc achieved lower grades at several of its mines; First Majestic Silver Corp.'s San Martin Mine and Endeavour Silver's El Cubo Mine were placed on care and maintenance; and blockades resulted in Newmont Corporation's Peñasquito Mino being suspended for 90 days.

Pricing and Outlook

        A combination of a slightly higher demand and a slightly higher supply in 2019 compared to 2018 resulted in a surplus of 31.3 million ounces, or 3.1% of silver demand, according to The Silver Institute's World Silver Survey 2020. Net investment in exchange traded products of 81.7 million ounces helped to propel the net silver balance to a 50 million ounce deficit, or approximately 5% of demand.

        In 2019, the average London Bullion Market Association ("LBMA") silver price increased 3.4% year-over-year to $16.21/oz. In 2019, the price of silver reached a high of $19.31/oz, a low of $14.38/oz and ended the year at $18.05/oz. The largest contributor to silver price movements is believed to be the ongoing trade dispute between the U.S. and China, which has had the impact of strengthening the U.S.

dollar and weighing on the price of silver and other precious metals. The U.S. Federal Reserve took a dovish stance through 2019, as it lowered the federal funds rate three times.

        The price of silver rallied strongly to multi-year highs in August 2020. As of August 31, 2020, the LBMA silver price has increased 52% compared to the year-end 2019 price. The recent silver price appreciation is believed to have been driven by accommodative monetary policy, aggressive stimulus measures and accelerating investment demand in the midst of the COVID-19 pandemic, as well as disrupted production and a recovery in industrial consumption. These factors have enhanced silver's appeal to investors seeking a hedge against inflation, a decrease in the value of the U.S. dollar and inflation, attracting investors during timesgeneral economic and geopolitical uncertainty. Trading volumes at futures and options exchanges have increased significantly, and exchange-traded products ("ETPs") inflows have been strong. As of uncertainty. GFMS data indicatesAugust 31, 2020, silver has a long-term research analyst average consensus price outlook of $18.75/oz.

Additional Resource Growth Potential from Exploration of the Los Gatos District

        In addition to the significant existing resources at the Cerro Los Gatos Mine, the Los Gatos District also contains the Esther and Amapola deposits and 11 other mineralized zones. With control of the concessions, the ability to develop the entire 103,087-hectare land position and more than 85% of the land position yet to be explored, we expect that we will stand to benefit from mineralization beyond those already identified in the 14 mineralized zones, which include the Cerro Los Gatos Mine, the

Assets Located in Geopolitically Safe and Established Mining Regions

Sunshine Silver’s principal assets are located in two of the world’s premier silver regions.        The Sunshine Mine propertyLos Gatos District is located in one of the Coeur d’Alene Mining District in Idaho, which district is estimated to have produced over one billion ounces ofworld's premier silver over approximately the last century, and the Los Gatos Project is located inmining regions: the Mexican Silver Belt, which was the world’sworld's largest silver producing region in 2011. In2019. Based on a survey published in 2019 by the Fraser Institute, an independent research organization, Mexico is highly ranked among silver mining jurisdictions worldwide in terms of the attractiveness of investment. Mexico also has a long history of successful mineral development and operations, which we believe makes it a desirable jurisdiction in which to conduct mining operations due to stable political, tax and regulatory policies.

        Mexico is the largest producer of silver in the world, in addition to being locateda top-10 producer of gold, lead and zinc, among other major commodities. According to the 2019 Fraser Institute survey, Mexico ranks ahead of many countries in premier silver regions, both assets possess characteristics that differentiate them from other silver projects:

Sunshine Mine Historical Production and Recent Accomplishments Enhance Operating SuccessSite Exploration Potential Provides Opportunity for Significant Resource Conversion Beyond Existing Mine Plan

Sunshine Silver believes        We believe that the significant historical production at the Sunshine Mine, combined with the recent and planned mine improvements, lowers project risk and enhances the likelihood of operating success of the project. Significant time and capital investment will be required before the Sunshine Mine returns to production and the Company anticipates that it will continue to incur operating costs without realizing any revenues at the Sunshine Mine until at least late 2014, including costs related to intensive underground exploration, rehabilitation and refurbishment of mine and processing infrastructure and further dewatering of underground workings. The underground workings consist of multiple levels developed off the main production shaft, extending from the surface to a depth of over 1,825 meters, or more than 1,000 meters below sea level.

Since acquiring the Sunshine Mine, the Company has acquired additional surface rights and improved the existing infrastructure, repaired surface facilities and equipment, completed a number of environmental, health and safety upgrades and identified and accessed a newly discovered portion of the resource that could be mined in the near future. The Company has added experienced and highly-trained professionals to lead such improvements. The Company has accomplished the following at the Sunshine Mine:

Initiated and expanded exploration drilling

Discovered an extension of the Sunshine Vein across the Chance Fault, an extension of the Yankee Boy Split Vein and the new “10” vein

Retained project engineering and development managers

Engaged geologic resource, metallurgical, environmental, hydrologic and mine planning consultants

Initiated metallurgical design work for a new process plant

Initiated a third party concentrate marketing study for silver-bearing concentrates

Managed the completion of a 3D block model with over 130,000 data points

Started modernizing the Silver Summit shaft and mined two declines for exploration platforms and access within the mine

Completed an independent technical report in accordance with NI 43-101 and the requirements of Industry Guide 7

Completed a preliminary economic assessment, which indicated mineralized material production could begin in the second quarter of 2014

Significant Exploration Potential for Additional Silver Resources

Sunshine Silver believes that itsour properties have significant exploration upside with numerous opportunities to define additional mineral resources through continued exploration of its properties:exploration.

Los Gatos District

        The Los Gatos District is located in the Mexican Silver Belt, near several other silver assets owned by large public companies. The Mexican Silver Belt has experienced significant exploration success, and the Los Gatos District represents an underexplored property where there has been little historical workings or previous exploration.

        The property has numerous well-defined exploration targets, many of which are extensions of past-producing silver veins. In addition, Sunshine Silver has acquired additionalLGJV owns the surface rights to further consolidate its ownership of this mineralized trend. Despite being a prolific silver producing region, Sunshine Silver believes that the Coeur d’Alene Mining District is still highly under explored. Through application of modern exploration technologies and processes, Sunshine Silver has discovered an extension of the Sunshine Vein across the Chance fault and several other high-grade veins and vein extensions.

Los Gatos Project: Sunshine Silver expects to expand5,479 hectares covering the Cerro Los Gatos Mine and the Esther and Amapola deposits and the Gavilana (Paula) and San Luis zones, and has been granted mineral concessions for all 103,087 hectares, with 17 contiguous concessions in the Los Gatos District. We have identified 14 mineralized zones within the concessions. Of the 14 mineralized zones, the LGJV has established mineral resource estimates only at the Cerro Los Gatos Mine, the Esther deposit and the Amapola deposit and has conducted drilling on only 15 kilometers out of a strike length of over 150 kilometers of quartz veining along the Los Gatos District.

        The current resources are significant, but we believe that additional resource potential remains in the immediate area. Drill testing of other high-priority targets within the Los Gatos District has been relatively limited given our focus on delineation of reserves at, and construction of, the Cerro Los Gatos Mine. As a result, the highly prospective Los Gatos District remains underexplored. Drilling at the Esther deposit to date has demonstrated good grade continuity along the system and characteristics similar to that identified during preliminary work at the Cerro Los Gatos Mine. Following potentially positive results from infill drilling at the Esther and Amapola deposits, we expect to update the

Politically Stable and Mining-Friendly JurisdictionsExposure to Rapidly Improving Silver Fundamentals

Both Idaho        The value of silver is driven by two main factors: first, silver has a number of distinctive physical and Mexico are jurisdictions with a long historychemical properties that make it an essential and difficult-to-substitute component in several industrial applications; and second, in times of successful mineral development and operations. Both are considered desirable jurisdictions in which to conduct mining operations due to stable political, tax and regulatory policies. Based on a survey published in February 2012 by the Fraser Institute, an independent research organization, Idaho and Mexico rank among the top silver mining jurisdictions worldwide in terms of the attractiveness of government policies, access to infrastructure and qualified labor availability.

Attractive Market Dynamics

Recent Developments

Re-CommissionImpact of the COVID-19 Pandemic

        In late March 2020, the Mexican government declared a national health emergency due to increasing infection rates from the COVID-19 pandemic. Pursuant to the health emergency declaration, the Mexican government ordered a temporary suspension of all "non-essential" operations nationwide in Mexico, including mining operations, in order to help combat the spread of COVID-19. In response to the order, the LGJV effected a 45-day temporary suspension of all non-essential activities at the Cerro Los Gatos Mine site, which reduced the number of employees and contractors at the site and the Chihuahua corporate office. During the temporary suspension, the LGJV implemented health protocols, allowed most administrative and technical services employees to work remotely, reduced mining and milling, completed project enhancements and finalized a mine plan upon reactivation of mining activities after the temporary suspension.

        In late May 2020, the Mexican government designated mining an essential service and allowed mines to resume production, subject to deploying COVID-19 prevention protocols. Our existing COVID-19 protocols exceeded those mandated by the Mexican government and, accordingly, the LGJV reactivated mine development and mining in late May 2020 and hired additional employees. Ore processing resumed in early June 2020. In order to maintain social distancing and best practice protocols, public areas, such as the residential camps' cafeterias, limited the number of personnel. Food service periods were extended with employees assigned specific times for meals. Face masks are required in offices and other public areas. Daily working shift times are staggered to limit the number of employees in changing areas and pre-shift work meetings. Two sterilization tunnels have been installed at the main entry gate and at the entrance to the cafeteria. All individuals entering the Cerro Los Gatos Mine site are subject to a rapid test to screen for COVID-19 and, if an individual tests positive on the rapid test and on a secondary molecular test, the individual will be subject to quarantine protocols and removed from the mine site. In the event of an outbreak of COVID-19 on site, we could determine that a full suspension of our operations is necessary for the safety and protection of the workers.

        The COVID-19 pandemic has temporarily affected our financial condition, in part due to the loss of revenue resulting from the 45-day temporary suspension of all non-essential activities at the LGJV's Cerro Los Gatos Mine site and the expenses associated with the development and implementation of COVID-19 protocols. In addition, as the LGJV reactivated mine development and mining, it implemented a scalable optimized plan with a lower employee complement and with reduced average monthly production rate at 1,750 tpd until September 2020, targeting higher ore grades. This may result in higher per tonne mining, processing and sustaining capital costs than previously anticipated. We intend to ramp up to the 2,500 tpd design capacity beginning in September 2020 with the goal of reaching the 2,500 tpd design capacity in January 2021.

        If the Mexican government were to reinstate the suspension order caused by the COVID-19 pandemic, or if all mining activities at the Cerro Los Gatos Mine site were suspended for an undefined period of time, there could be additional costs incurred, production and development delays, cost overruns and operational restart costs. In addition, given that our management travels regularly between Mexico City and the Cerro Los Gatos Mine site, any restrictions on travel within Mexico may adversely affect our management's ability to oversee ongoing mining activities at the Cerro Los Gatos Mine and our ability to achieve our business objectives and milestones. See "Risk Factors—Risks Related to Our Business and Industry—Our business could be adversely affected by the effects of health epidemics, including the recent COVID-19 pandemic, in regions where we conduct our business operations."

    we have a history of negative operating cash flows and net losses and we may never achieve or sustain profitability;

    we are dependent on two principal projects for our future operations, the Cerro Los Gatos Mine and the Los Gatos District; the Los Gatos District (other than the Cerro Los Gatos Mine) does not currently have proven or probable mineral reserves;

    mineral reserve and mineral resource calculations at the Cerro Los Gatos Mine and the Los Gatos District are only estimates;

    actual capital costs, operating costs, production and economic returns may differ significantly from those we have anticipated and there are no assurances that any future development activities will result in profitable mining operations;

    the title to some of the mineral properties may be uncertain or defective, thus risking our investment in such properties;

    the prices of silver, zinc and lead are subject to change and a substantial or extended decline in the prices of silver, zinc or lead could materially and adversely affect our revenues and the value of our mineral properties;

    we may be subject to claims and legal proceedings that could materially and adversely impact our financial position, financial performance and results of operations;

    we have debt and may incur further debt in the future, which could adversely affect our financial health, limit our ability to obtain financing in the future and pursue certain business opportunities and reduce the value of your investment;

    our directors may have conflicts of interest as a result of their relationships with other mining companies;

    our business could be adversely affected by the effects of health epidemics, including the recent COVID-19 pandemic, in regions where we conduct our business operations;

    our success depends on developing and maintaining relationships with local communities and stakeholders;

    the Mexican government, as well as local governments, extensively regulate mining operations, which impose significant actual and potential costs on us, and future regulation could increase those costs, delay receipt of regulatory refunds or limit our ability to produce silver and other metals;

    Electrum, MERS and their respective affiliates will continue to have a substantial degree of control over us after this offering, which could delay or prevent a change of corporate control or result in the entrenchment of our management and/or Board of Directors;

    our relationship with SOP may strain our senior management resources and could potentially result in conflicts of interest; and

    we are an "emerging growth company" and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

Implications of Becoming an Emerging Growth Company

        As a company with less than $1.07 billion in revenue during our last fiscal year, we qualify as an "emerging growth company" as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). An emerging growth company may take advantage of specified reduced reporting and other requirements that are otherwise applicable generally to public companies. These provisions include:

    we are not required to engage an auditor to report on our internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act");

    we are not required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board (the "PCAOB") regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements (i.e., an auditor discussion and analysis);

    we are not required to submit certain executive compensation matters to shareholder advisory votes, such as "say-on-pay," "say-on-frequency" and "say-on-golden parachutes"; and

    we are not required to disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the chief executive officer's compensation to median employee compensation.

        We may take advantage of these provisions until the last day of our fiscal year following the fifth anniversary of the completion of this offering or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company upon the earliest of: (i) the last day of the first fiscal year in which our annual gross revenues are $1.07 billion or more; (ii) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt securities; or (iii) the date on which we are deemed to be a "large accelerated filer," which will occur as of the end of any fiscal year in which we (x) have an aggregate market value of our common stock held by non-affiliates of $700 million or more as of the last business day of our most recently completed second fiscal quarter, (y) have been required to file annual and quarterly reports under the Securities and Exchange Act of 1934, as amended (the "Exchange Act"), for a period of at least 12 months and (z) have filed at least one annual report pursuant to the Exchange Act. Even after we no longer qualify as an emerging growth company, we may still qualify as a "smaller reporting company," which would allow us to take advantage of many of the same exemptions from disclosure requirements including reduced disclosure obligations regarding executive compensation in this prospectus and our periodic reports and proxy statements.

        We have elected to take advantage of some of the reduced disclosure obligations listed above in this prospectus and may elect to take advantage of other reduced reporting requirements in future filings. In particular, we have elected to adopt the reduced disclosure with respect to our executive compensation disclosure. As a result of this election, the information that we provide to shareholders may be different from that you might get from other public companies.

        The JOBS Act permits an emerging growth company like us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to "opt out" of this provision and, as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for public companies that are not emerging growth companies. The decision to opt out of the extended transition period under the JOBS Act is irrevocable.

Corporate Information and Reorganization

        We were formed on February 2, 2011, when our predecessor Precious Metals Opportunities LLC, which was formed in December 2009, converted to a Delaware corporation. On March 1, 2011, Los Gatos Ltd. merged with and into us to form Sunshine Silver Mines Corporation. In 2014, we changed our name to Sunshine Silver Mining & Refining Corporation.

        Immediately prior to the closing of this offering, we intend to effect the Reorganization in which (i) SOP will convert into a Delaware corporation named Silver Opportunity Partners Corporation, (ii) each            shares of our common stock outstanding immediately prior to the Reorganization will be reclassified into (A)              shares of our common stock and (B)             shares of common stock of SOP Corporation and (iii) we will change our name from Sunshine Silver Mining & Refining Corporation to Gatos Silver, Inc. SOP currently holds our interest in the Sunshine Mine to Long-Term Sustainable Production

Sunshine Silver intends to upgrade or replace existing infrastructure atComplex, which is located in the Sunshine MineCoeur d'Alene Mining District in connection with its modernizationIdaho and rehabilitation efforts and to review process optimization alternatives. The re-commissioningis comprised of the Sunshine Mine will be designedand the Sunshine Big Creek Refinery. Through the Reorganization, we expect to allowdistribute all of our equity interest in SOP to our shareholders immediately prior to the Company to reach a safe and sustainable production rate utilizing its newly optimized facilities.completion of this offering.

        A chart of our project ownership structure after the Reorganization is set out below.

Silver Opportunity Partners LLC holds less than 0.01% interest in Minera Luz de Sol, S. de R.L. de C.V. due to requirements of the Los Gatos Project and Accelerate Exploration in the Los Gatos Region

The Company plans to accelerate its exploration program at the Los Gatos region through additional drilling with the intent of identifying additional mineralized material within the established ten additional target areas. In the near term, the Company also intends to progress the most advanced exploration sites, the Cerro Los Gatos, Esther and Amapola zones, through additional in-fill and stepout drilling (expected to recommence in the second quarter of 2013), beginning decline development (expected to commence in the first quarter of 2014) and completion of a pre-feasibility study.

Conduct Further Exploration at Sunshine Silver’s Mexican Properties Outside the Los Gatos Region and Apply for Additional Exploration Acreage

Sunshine Silver plans to expand its exploration programs at its Mexican properties outside the Los Gatos region and continue to grow its land position. The Company owns or controls a portfolio of 19 other exploration properties in Mexico covering an area of 420,895 hectares, with significant additional hectares under application

for mineral concession. There are three projects underway with significant drill results: El Doctor in Oaxaca, Santa Valeria in Chihuahua and Zacatlan in Puebla. Additional drilling is planned at these projects as well as additional targets through 2013. The Company is planning sufficient drilling in an effort to outline continuous geometry of mineralization at El Doctor, Santa Valeria and Zacatlan, which could lead to initial estimates of mineralized material.

Identify and Pursue Other Growth Opportunities that Add Value to Stockholders

Given the management and Board’s strong track record in exploration, development and asset integration, the Company may pursue acquisitions and joint ventures that are value accretive to its stockholders through the pursuit of similarly attractive silver-focused projects.

Recent Developments

Exploration drilling at the Sunshine Mine property in Idaho from accessible underground workings has resulted in the discovery of a new deeper vein referred to as the “10 vein,” a mineralized extension to the Sunshine vein in a previously unexplored area and continuity of the South Yankee Boy and Yankee Boy Split veins. Results from recent drilling are as follows:

RISK FACTORS

You should carefully consider the following risk factors that may affect our business, future operating results and financial condition, as well as the other information set forth in this prospectus, before making a decision to invest in our common stock. If any of the following risks actually occurs, our business, financial condition or results of operations would likely be materially and adversely affected. In such case, the trading price of our common stock would likely decline, and you may lose all or part of your investment. The risks below are not the only ones we face. Additional risks not currently known to us or that we currently deem immaterial may also adversely affect us.

Risks Related to Our Business and Industry

We are an exploration company that has nohave a history of negative operating history on which to base an evaluation of our businesscash flows and prospectsnet losses and we cannot provide investors with any assurance that we will generate any operating revenues at our mineral propertiesmay never achieve or ever achieve profitable operations.sustain profitability.

We were formed in December 2009have a history of negative operating cash flows and have not yet generated any operating revenue. The Sunshine Mine has not been a producing mine since 2008, prior to its acquisition by us. We anticipate that we will continue to incur operating costs without realizing any revenues at the Sunshine Mine until at least late 2014 and for the foreseeable future at the Los Gatos Project.net losses. We expect to continue to incur negative operating cash flows and net losses until such time as one or more of our mineral properties enters into commercial production and generates sufficient revenues to fund our continuing operations. IfFor the years ended December 31, 2019 and 2018, our net loss was $37.8 million and $11.7 million, respectively, and for the six months ended June 30, 2020 and 2019, our net loss was $30.0 million and $18.0 million, respectively. For the six months ended June 30, 2019, on a pro forma basis after giving effect to the Reorganization, our net loss would have been $             million. Given our history of negative operating cash flows and net losses, and potential future negative operating cash flows and net losses, we are unablemay use the net proceeds from this offering to generatefund our continuing operations. See "Use of Proceeds."

        We may never achieve or sustain profitability. The Cerro Los Gatos Mine commenced production on September 1, 2019. To become and remain profitable, we must succeed in generating significant revenues at the Sunshine Mine or theCerro Los Gatos Project, weMine, which will not be ablerequire us to earn profits or continue operations. We cannot provide investors with any assurance that we will be successful in resuming productiona range of challenging activities and is subject to numerous risks, including the risk factors set forth in this "Risk Factors" section. In addition, we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our revenues, expenses and profitability. Our failure to achieve or sustain profitability would depress our market value, could impair our ability to execute our business plan, raise capital or continue our operations and could cause our shareholders to lose all or part of their investment.

There is substantial doubt about our ability to continue as a going concern.

        Our recurring negative operating cash flows and net losses raise substantial doubt about our ability to continue as a going concern. Our ability to continue operating as a going concern is contingent upon our ability to secure sufficient financing, retire certain existing obligations and/or reduce spending to maintain operations. Based on our planned use of the net proceeds of this offering and our currently available resources, including existing cash and cash equivalents, we estimate that such funds will enable us to fund our projected operating expenses and capital expenditures for at least twelve months from the Sunshine Mine, ordate of this prospectus. This estimate is based on assumptions that may prove to be wrong, and we will ever developcould use our available capital resources sooner than we currently expect. Changing circumstances could cause us to consume capital significantly faster than we currently anticipate, and we may need to spend more than currently expected because of circumstances beyond our control. The financial statements contained elsewhere in this prospectus do not include any adjustments that might result from our inability to continue as a mine at the Los Gatos Project.going concern.

We are dependent on our two principal projects for our future operating revenue,operations, the SunshineCerro Los Gatos Mine property and the Los Gatos Project, neither of whichDistrict. The Los Gatos District (other than the Cerro Los Gatos Mine) does not currently hashave proven or probable mineral reserves.

The Sunshine Mine property and the Los Gatos Project doDistrict (other than the Cerro Los Gatos Mine) does not have identified proven and probable mineral reserves. The costs, timing and complexities of upgrading the mineralized material at the Sunshine Mine property to proven and probable reserves may be greater than we anticipate. Mineral exploration and development involves a high degree of risk that even a combination of careful evaluation, experience and knowledge cannot eliminate, and few properties that are explored are ultimately developed into producing mines. There is no assurance that our mineral exploration programs at either the Sunshine Mine property or the Los Gatos ProjectDistrict will establish the presence of any additional proven or probable mineral reserves. The failure to establish additional proven or probable mineral reserves would severely restrict our ability to implement our strategies for long-term growth.

Mineralized materialMineral reserve and mineral resource calculations at the SunshineCerro Los Gatos Mine and the Los Gatos ProjectDistrict are only estimates.

Our calculation        Calculations of mineral reserves at the Cerro Los Gatos Mine and of the mineralized materialmineral resources at the Sunshine Mine and the Los Gatos ProjectDistrict are only estimates and depend on geological interpretation and statistical inferences or assumptions drawn from drilling and sampling analysis, which might prove to be materially inaccurate. There is a degree of uncertainty attributable to the calculation of mineralized material.mineral reserves and mineral resources. Until mineralized material ismineral reserves and mineral resources are actually mined and processed, the quantity of metal and grades must be considered as estimates only and no assurance can be given that the indicated levels of metals will be produced. In making determinations about whether to advance any of our projects to development, we must rely upon estimated calculations for the mineralized materialmineral reserves and mineral resources and grades of mineralization on our properties.

The estimation of mineralized materialmineral reserves and mineral resources is a subjective process that is partially dependent upon the judgment of the persons preparing the estimates. The process relies on the quantity and quality of available data and is based on knowledge, mining experience, statistical analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available.

Estimated mineralized materialmineral reserves and mineral resources may have to be recalculated based on changes in metal prices, further exploration or development activity or actual production experience. This could materially and adversely affect estimates of the volume or grade of mineralization, estimated recovery rates or other important factors that influence mineralized materialmineral reserves and mineral resources estimates. The extent to which mineralized materialmineral resources may ultimately be reclassified as mineral reserves is dependent upon the demonstration of their profitable recovery. Any material changes in volume and grades of mineralization will affect the economic viability of placing a property into production and a property’sproperty's return on capital. We cannot provide assurance that mineralization can be mined or processed profitably.

Our mineralized material        Mineral reserve and mineral resource estimates have been determined and valued based on assumed future metal prices, cut-off grades and operating costs that may prove to be inaccurate. Extended declines in the market price for silver, lead and zinc may render portions of our mineralization uneconomic and result in reduced reported volume and grades, which in turn could have a material adverse effect on our financial performance, financial position and results of operations.

        In addition, inferred mineral resources have a great amount of uncertainty as to their existence and their economic and legal feasibility. You should not assume that any part of an inferred mineral resource will be upgraded to a higher category or that any of the mineral resources not already classified as mineral reserves will be reclassified as mineral reserves.

Our mineral exploration efforts are highly speculative in nature and may be unsuccessful.

        Mineral exploration is highly speculative in nature, involves many uncertainties and risks and is frequently unsuccessful. It is performed to demonstrate the dimensions, position and mineral characteristics of mineral deposits, estimate mineral resources, assess amenability of the deposit to mining and processing scenarios and estimate potential deposit value. Once mineralization is discovered, it may take a number of years from the initial exploration phases before production is possible, during which time the potential feasibility of the project may change adversely. Substantial expenditures are required to establish additional proven and probable mineral reserves, to determine processes to extract the metals and, if required, to construct mining and processing facilities and obtain the rights to the land and resources required to develop the mining activities.

        Development projects have no operating history upon which to base estimates of proven and probable mineral reserves and estimates of future operating costs. Estimates are, to a large extent, based upon the interpretation of geological data and modeling obtained from drill holes and other sampling techniques, feasibility studies that derive estimates of operating costs based upon anticipated tonnage and grades of material to be mined and processed, the configuration of the deposit, expected recovery rates of metal from the mill feed material, facility and equipment capital and operating costs, anticipated climatic conditions and other factors. As a result, actual operating costs and economic returns based upon development of proven and probable mineral reserves may differ significantly from those originally estimated. Moreover, significant decreases in actual or expected commodity prices may mean mineralization, once found, will be uneconomical to mine.

Our processing ability may be adversely impacted by certain circumstances.

        A number of factors could affect our ability to process the quantities of metals that we recover and our ability to efficiently handle certain quantities of processed materials, including, but not limited to, the presence of oversized material at the crushing stage; material showing breakage characteristics different than those planned; material with grades outside of planned grade range; the presence of deleterious materials in ratios different than expected; material drier or wetter than expected, due to natural or environmental effects; and materials having viscosity or density different than expected.

        The occurrence of one or more of the circumstances described above could affect our ability to process the number of tonnes planned, recover valuable materials, remove deleterious materials, and produce planned quantities of concentrates. In turn, this may result in lower throughput, lower recoveries, increased downtime or some combination of all of the foregoing. While issues of this nature are part of normal operations, there is no assurance that unexpected conditions may not materially and adversely affect our business, results of operations or financial condition.

Actual capital costs, operating costs, production and economic returns may differ significantly from those we have anticipated and there are no assurances that any future development activities will result in profitable mining operations.

The capital costs to take the Sunshine Mine into production may be significantly higher than those set forth in the Sunshine Mine Technical Report and Preliminary Economic Assessment. We may ultimately base our decisions about the development of the Sunshine Mine on a feasibility study. We have not prepared a feasibility study for the Sunshine Mine, but we may use a portion of the proceeds of the offering to produce one if we deem it necessary or appropriate to do so. Our evaluations of our business and prospects are subject to change, including after any feasibility study has been conducted, which could materially adversely affect our prospects.

Additionally, the actual amount of operating costs at the SunshineCerro Los Gatos Mine will depend upon changes in the availability and prices of labor, equipment and infrastructure, variances in ore recovery and mining rates from those assumed in the mining plan, operational risks, changes in governmental regulation, including taxation, environmental, permitting and other regulations and other factors, many of which are beyond our control. Due to any of these or other factors, the operating costs at the SunshineCerro Los Gatos Mine may be significantly higher than those set forth in the Sunshine MineLos Gatos Technical Report and Preliminary Economic Assessment.Report. As a result of higher capital and operating costs, production and economic returns may differ significantly from those set forth in the Sunshine MineLos Gatos Technical Report and Preliminary Economic Assessment and there are no assurances that any future development activities will result in profitable mining operations.


Historical production at the Sunshine Mine may not be indicativeTable of the potential for future development.Contents

There is currently no commercial production at the Sunshine Mine and, since acquiring ownership, we have never recorded any revenues from commercial production at the Sunshine Mine. You should not rely on the fact that there were historical mining operations at the Sunshine Mine as an indication that we will ever have future successful commercial operations at the Sunshine Mine. In order for us to develop new mining operations at the Sunshine Mine, we will be required to incur substantial operating expenses and capital expenditures to refurbish and/or replace existing infrastructure.

Land reclamation and mine closure may be burdensome and costly.

Land reclamation and mine closure requirements are generally imposed on mineral exploration companies, such as ours, which require us, among other things, to minimize the effects of land disturbance. Such requirements may include controlling the discharge of potentially dangerous effluents from a site and restoring a site’ssite's landscape to its pre-exploration form. The actual costs of reclamation and mine closure are uncertain and planned expenditures may differ from the actual expenditures required. Therefore, the amount that we are required to spend could be materially higher than current estimates. Any additional amounts required to be spent on reclamation and mine closure may have a material adverse effect on our financial performance, financial position and results of operations

and may cause us to alter our operations. In addition, we are required to maintain financial assurances, such as letters of credit, to secure reclamation obligations under certain laws and regulations. The failure to acquire, maintain or renew such financial assurances could subject us to fines and penalties or suspension of our operations. Letters of credit or other forms of financial assurance represent only a portion of the total amount of money that will be spent on reclamation over the life of a mine’smine's operation. Although we include liabilities for estimated reclamation and mine closure costs in our financial statements, it may be necessary to spend more than what is projected to fund required reclamation and mine closure activities. Additionally, even if we cease exploration at the Sunshine Mine we will be required to expend cash and other resources to satisfy ongoing care and maintenance obligations at the Sunshine Mine, which obligations include controlling ground water, monitoring and sampling permitted facilities and ultimately reclaiming our tailings impoundment.

We do not have sufficient funds to bring the Sunshine Mine into sustained commercial operation or to develop a mine at the Los Gatos Project, and we expect that we will require additional financing in the future.

We are an exploration company and do not currently have sufficient capital for sustained operations. We expect that the proceeds from this offering will be used to construct a processing plant for silver-bearing concentrate, construct a new refinery and bring the Sunshine Mine to sustained commercial development. We may also use a portion of the proceeds to complete a feasibility study at the Sunshine Mine. In addition, we plan to complete a pre-feasibility study, conduct exploration drilling and initiate a development decline at the Los Gatos Project. However, we do not expect that the funds raised from this offering will be sufficient to develop a mine at the Los Gatos Project. Our future financing needs may be substantial if we encounter unexpected costs or delays in re-commissioning the Sunshine Mine or developing a mine at the Los Gatos Project.

We expect to raise additional funds through equity, debt, joint venture funding or some combination thereof. Access to additional capital may not, however, be available on terms acceptable to us or at all. Failure to obtain sufficient financing may result in the delay or indefinite postponement of exploration, drilling, development or production at the Sunshine Mine or the Los Gatos Project. Furthermore, even if we raise sufficient additional capital, there can be no assurance that we will achieve profitability or positive cash flow. In addition, any future equity offering will further dilute your equity interest in us and any future debt financing will require us to dedicate a portion of our cash flow to payments on indebtedness and will limit our flexibility in planning for or reacting to changes in our business.

If theThe development of one or more of our mineral projects isthat have been, or may in the future be, found to be economically feasible we will be subject to all of the risks associated with establishing new mining operations.

        The Los Gatos Technical Report indicates that the Cerro Los Gatos Mine is a profitable silver-zinc-lead project with an estimated 11-year mine life, at modeled metals' prices. If the development of one of our other mineral projects is found to be economically feasible, the development of such developmentprojects will require obtaining permits and financing, and the construction and operation of mines, processing plants and related infrastructure. As a result, we will be subject to all of thecertain risks associated with establishing new mining operations, including:

    the timing and cost, which can be considerable, of the construction of mining and processing facilities and related infrastructure;



the availability and cost of skilled labor, mining equipment and principal supplies needed for operations, including explosives, fuels, chemical reagents, water, power, equipment parts and lubricants;



the availability and cost of appropriate smelting and refining arrangements;



the need to obtain necessary environmental and other governmental approvals and permits and the timing of the receipt of those approvals and permits;



the availability of funds to finance construction and development activities;



industrial accidents;



mine failures, shaft failures or equipment failures;



natural phenomena such as inclement weather conditions, floods, droughts, rock slides and seismic activity;



unusual or unexpected geological and metallurgicmetallurgical conditions;



exchange rate and commodity price fluctuations;



high rates of inflation;

health pandemics, including the COVID-19 pandemic;

    potential opposition from non-governmental organizations, environmental groups or local groups, which may delay or prevent development activities; and



restrictions or regulations imposed by governmental or regulatory authorities.

authorities, including with respect to environmental matters.

The costs, timing and complexities of developing ourthe projects may be greater than anticipated. Cost estimates may increase significantly as more detailed engineering work is completed on a project. It is common in mining operations to experience unexpected costs, problems and delays during construction, development and mine start-up. In addition, the cost of producing silver-bearing concentrates that are of acceptable quality to smelters may be significantly higher than expected. We may encounter higher than acceptable contaminants in our concentrates such as arsenic, antimony, mercury, copper, iron, selenium or other contaminants that, when present in high concentrations, can result in penalties or outright rejection of the metals concentrates by the smelters. Silver-bearing concentratessmelters or offtakers. For example, due to the high fluorine content at our Sunshinethe Cerro Los Gatos Mine, are knownit was necessary to contain relatively high percentagesreduce the fluorine content of arsenic and antimony.the concentrate produced at the Cerro Los Gatos Mine by providing additional cleaning stages. Accordingly, we cannot provide assurance that our activities will result in profitable mining operations at ourthe mineral properties.

Our operations involve significant risks and hazards inherent to the mining industry.

Our operations involve the operation of large pieces ofmachines, heavy mobile equipment and drilling and other heavy equipment. Hazards such as fire, explosion, floods, structural collapses,adverse environmental conditions, industrial accidents, labor disputes, unusual or unexpected geological conditions, ground control problems, cave-ins, floodingchanges in the regulatory environment, metallurgical and other processing problems, mechanical equipment failure, facility performance problems, fire and natural phenomena such as inclement weather conditions, floods and earthquakes are inherent risks in our operations. For example, in February 2012, we had a fire at the Sunshine Mine. The fire was extinguished in March 2012, access to the upper levels was reestablished in April 2012, and access to the lower levels was reestablished in June 2012. Through December 31, 2012, we have incurred $1.55 million of direct costs related to the Sunshine Mine fire. Hazards inherent to the mining industry can cause injuries or death to employees, contractors or other persons at our mineral properties, severe damage to and destruction of our property, plant and equipment, and mineral properties, and contamination of, or damage to, the environment, and can result in the suspension of our exploration activities and any future development and production activities. While the Company aimswe aim to maintain best safety practices as part of its culture, safety measures implemented by us may not be successful in preventing or mitigating future accidents.

In addition, from time to time we may be subject to governmental investigations and claims and litigation filed on behalf of persons who are harmed while at our properties or otherwise in connection with our operations. To the extent that we are subject to personal injury or other claims or lawsuits in the future, it may not be possible to predict the ultimate outcome of these claims and lawsuits due to the nature of personal injury litigation. Similarly, if we are subject to governmental investigations or proceedings, we may incur significant penalties and fines, and enforcement actions against us could result in the closing of certain of our mining operations. If claims and lawsuits or governmental investigations or proceedings are ultimately resolved against us, it could have a material adverse effect on our financial performance, financial position and results of operations. Also, if we mine on property without the appropriate licenses and approvals, we could incur liability or our operations could be suspended.

We may be materially and adversely affected by challenges relating to slope and stability of underground openings.

        Our underground mines get deeper and our waste and tailings deposits increase in size as we continue with and expand our mining activities, presenting certain geotechnical challenges, including the possibility of failure of underground openings. If we are required to reinforce such openings or take additional actions to prevent such a failure, we could incur additional expenses, and our operations and stated mineral reserves could be negatively affected. We have taken the actions we determined to be


Table of Contents

proper in order to maintain the stability of underground openings, but additional action may be required in the future. Unexpected failures or additional requirements to prevent such failures may adversely affect our costs and expose us to health and safety and other liabilities in the event of an accident, and in turn materially and adversely affect the results of our operations and financial condition, as well as potentially have the effect of diminishing our stated mineral reserves.

The mining industry is very competitive.

The mining industry is very competitive. Much of our competition is from larger, established mining companies with greater liquidity, greater access to credit and other financial resources, newer or more efficient

equipment, lower cost structures, more effective risk management policies and procedures and/or a greater ability than us to withstand losses. Our competitors may be able to respond more quickly to new laws or regulations or emerging technologies, or devote greater resources to the expansion or efficiency of their operations than we can. In addition, current and potential competitors may make strategic acquisitions or establish cooperative relationships among themselves or with third parties. Accordingly, it is possible that new competitors or alliances among current and new competitors may emerge and gain significant market share to our detriment. We may not be able to compete successfully against current and future competitors, and any failure to do so could have a material adverse effect on our business, financial condition or results of operations.

Deliveries under a sales agreement with Ocean Partners and other customer concentrate sales agreements may be suspended or cancelled by our customers in certain cases.

        Under a sales agreement with Ocean Partners USA Inc. ("Ocean Partners") and other customer concentrate sales agreements, our customers may suspend or cancel delivery of our products in some cases, such as force majeure. Events of force majeure under these agreements generally include, among others, acts of God, strikes, fires, floods, wars, government actions or other events that are beyond the control of the parties involved. Any suspension or cancellation by our customers of deliveries under our sales contracts that are not replaced by deliveries under new contracts would reduce our cash flow and could materially and adversely affect our financial condition and results of operations.

The title to some of ourthe mineral properties may be uncertain or defective, thus risking our investment in such properties.

Certain        Under the laws of our United StatesMexico, mineral resources belong to the state, and government concessions are required to explore for or exploit mineral reserves. Mineral rights consist of “patented” and “unpatented” mining claims created and maintained in accordance with the U.S. General Mining Law of 1872. Unpatented mining claims are unique U.S. property interests, and are generally considered to be subject to greater title risk than other real property interests because the validity of unpatented mining claims is often uncertain. This uncertainty arises, in part, out of the complex federal and state laws and regulations that supplement the General Mining Law. Also, unpatented mining claims and related rights, including rights to use the surface, are subject to possible challenges by third parties or contestsderive from concessions granted, on a discretionary basis, by the federal government. The validityMinistry of an unpatentedEconomy, pursuant to the Mexican mining claim, in terms of both its location and its maintenance, is dependent on strict compliance with a complex body of federal and state statutory and decisional law. In addition, there are few public records that definitively control the issues of validity and ownership of unpatented mining claims.

The Sunshine Mine property is part of a historic mining district that was established prior to 1900. The history of ownership of the properties comprising the Sunshine Mine property is complex and involves numerous individuals and entities. In addition, title to many of the mineralized veins at the Sunshine Mine property is based on ownership of the patented claims within which those veins have their apex, as under the General Mining Law the owner of a mining claim within which a mineralized vein has its apex owns the so-called “extralateral rights” to that vein as it may extend downward outside the vertical boundaries of the claim. As the vein extends downward, however, its actual location becomes less and less certain. As a result, ownership of these mineralized veins often becomes more a question of geology than of public records. Over the years, because of the age of the districtlaw and the existence of extralateral rights that renderregulations thereunder. While we and the LGJV hold title to the actual minerals beneath any particular claim more uncertain, our predecessors and adjoining landowners entered into several agreements establishing boundary lines between claims, dividing ownership of portions of claims, agreeing tomineral properties in Mexico described in this prospectus, including the sharing of ore produced from mineralized veins within claims, and agreeing to joint exploration and development activities on certain claims. There can beCerro Los Gatos Mine, through these government concessions, there is no assurance that title to the concessions comprising the Cerro Los Gatos Mine or our predecessors successfully consolidatedor the LGJV's other properties at the Sunshine Mine property so that third parties will not make claimsbe challenged or impaired. The Los Gatos concession is held by us subject to our properties or a sharethe terms of some portionan agreement with the original holder of any mineral production in the future or that we have identified every agreement establishing our property rights.

With respect to several of the patented mining claims at the Sunshine Mine property, we own the mineral estate but not the surface estate. Although we expect we would continue the development of the Sunshine Mine as an underground mine, which would not require us to make use of the surface of those patented claims where we do not own the surface estate, as we develop our mine plan for the Sunshineconcession. The Cerro Los Gatos Mine and as that plan changes over time, there can be no assurance that we will not need to useour or the surface of portions of those claims. If that need arises there can be no assurance that the owners of the surface estate of any of those claims will recognize our common law rights or be willing to enter into agreements with us to allow for such surface use.

Additionally, our mineralLGJV's other properties in Mexico may be subject to prior recorded and unrecordedunregistered agreements, transfersinterests or native land claims, and title may be affected by among other things,such undetected defects. A title defect on any of our mineral properties (or any portion thereof) could adversely affect our ability to mine the property and/or process the minerals that we mine.

        The mineral properties' mining concessions in Mexico may be terminated if the obligations to maintain the concessions in good standing are not satisfied, including obligations to explore or exploit the relevant concession, to pay any relevant fees, to comply with all environmental and safety standards, to provide information to the Mexican Ministry of Economy and to allow inspections by the Mexican Ministry of Economy. In addition to termination, failure to make timely concession maintenance

payments and otherwise comply with applicable laws, regulations and local practices relating to mineral right applications and tenure could result in reduction or expropriation of entitlements.

Title insurance is generally not available for mineral properties and our ability to ensure that we have obtained secure claim to individual mineral properties or mining concessions may be severely constrained. We rely on title information and/or representations and warranties provided by our grantors. Any challenge to our title could result in litigation, insurance claims and potential losses, delay the exploration and development of a property and ultimately result in the loss of some or all of our interest in the property. In addition, if we mine on property without the appropriate title, we could incur liability for such activities. While we have received a title opinion in relation to the Los Gatos District dated as of November 5, 2019, such opinion is not a guarantee of title and such title may be challenged.

We do not currently intend to enter into hedging arrangements with respect to silver and other minerals and our hedging activities, or our decision not to hedge, with respect to our expenses could expose us to losses. We are also subject to risks relating to fluctuations in the exchange rate of the Mexican peso to the U.S. dollar.

We do not currently intend to enter into hedging arrangements with respect to silver.silver and other minerals. As such, we will not be protected from a decline in the price of silver.silver and other minerals. This strategy may have a material adverse effect upon our financial performance, financial position and results of operations.

We report our financial statements in U.S. dollars. A portion of our costs and expenses are incurred in Mexican pesos. As a result, any significant and sustained appreciation of the Mexican peso against the U.S. dollar may materially increase our costs and expenses. Additionally, we are, and will be, exposed to the potentially adverse effects of fluctuations in input costs, such as diesel fuel, and if we borrow funds at a floating rate, interest rates. We may seek to enter into hedging arrangements to hedge some of our input costs, such as diesel fuel, and our currency exposure with respect to the portion of our costs and expenses incurred in Mexican pesos. In the future we may also seek to enter into interest rate hedge agreements in connection with future indebtedness we may incur that bears interest at a floating rate. We currently, however, have not entered into any such hedging arrangements, or made a decision to do so, and cannot assure you that we will be able to do so on acceptable terms, or at all. Even if we seek and are able to enter into hedging contracts, there is no assurance that such hedging program will be effective, and any hedging program would also prevent us from benefitting fully from applicable input cost or rate decreases. In addition, we may in the future experience losses if a counterparty fails to perform under a hedge arrangement.

Our insurance may not provide adequate coverage.

Our business and operations are subject to a number of risks and hazards, including, but not limited to, adverse environmental conditions, industrial accidents, labor disputes, unusual or unexpected geological conditions, ground control problems, cave-ins, changes in the regulatory environment, metallurgical and other processing problems, mechanical equipment failure, facility performance problems, fires and natural phenomena such as inclement weather conditions, floods and earthquakes. These risks could result in damage to, or destruction of, our mineral properties or production facilities, personal injury or death, environmental damage, delays in exploration, mining or processing, increased production costs, asset write downs, monetary losses and legal liability.

Our property and liability insurance may not provide sufficient coverage for losses related to these or other hazards. Insurance against certain risks, including those related to environmental matters or other hazards resulting from exploration and production, is generally not available to us or to other companies within the mining industry. Our current insurance coverage may not continue to be available at economically feasible premiums, or at all. In addition, we do not carryour business interruption insurance relating to


Table of Contents

our properties.properties has long waiting periods before coverage begins. Accordingly, delays in returning to any future production could produce near-term severe impact to our business. Any losses from these events may cause us to incur significant costs that could have a material adverse effect on our financial performance, financial position and results of operations.

Our business is sensitive to nature and climate conditions.

        A number of governments have introduced or are moving to introduce climate change legislation and treaties at the international, national, state/provincial and local levels. Regulations relating to emission levels (such as carbon taxes) and energy efficiency are becoming more stringent. If the current regulatory trend continues, this may result in increased costs at some or all of our business locations. In addition, the physical risks of climate change may also have an adverse effect on our operations. Extreme weather events have the potential to disrupt our exploration at our mines and may require us to make additional expenditures to mitigate the impact of such events.

Suitable infrastructure may not be available or damage to existing infrastructure may occur.

        Mining, processing, development and exploration activities depend on adequate infrastructure. Reliable roads, bridges, port and/or rail transportation, power sources, water supply and access to key consumables are important determinants for capital and operating costs. The lack of availability on acceptable terms or the delay in the availability of any one or more of these items could prevent or delay exploration, development or exploitation of our projects. If adequate infrastructure is not available in a timely manner, we cannot assure you that the exploitation or development of our projects will be commenced or completed on a timely basis, or at all, or that the resulting operations will achieve the anticipated production volume, or that the construction costs and operating costs associated with the exploitation and/or development of our projects will not be higher than anticipated. In addition, extreme weather phenomena, sabotage, vandalism, government, non-governmental organization and community or other interference in the maintenance or provision of such infrastructure could adversely affect our operations and profitability.

If we are unable to retain key members of management, our business might be harmed.

Our exploration activities and any future development and construction or mining and processing activities depend to a significant extent on the continued service and performance of our senior management team, including our Executive Chairman and

Chief Executive Officer. We depend on a relatively small number of key officers, and we currently do not, and do not intend to, have key-person insurance for these individuals. Departures by members of our senior management could have a negative impact on our business, as we may not be able to find suitable personnel to replace departing management on a timely basis.basis, or at all. The loss of any member of our senior management team could impair our ability to execute our business plan and could, therefore, have a material adverse effect on our business, results of operations and financial condition. In addition, the international mining industry is very active and we are facing increased competition for personnel in all disciplines and areas of operation. There is no assurance that we will be able to attract and retain personnel to sufficiently staff our development and operating teams.

High metalThe prices in recent years have encouraged increased mineral exploration, development and construction activity, which has increased demand for, and cost of, exploration, development and construction services and equipment.

High metal prices in recent years have encouraged increases in mineral exploration, development and construction activities, which has resulted in increased demand for, and cost of, exploration, development and construction services and equipment. There has also been a shortage of skilled workers in the mining industry in recent years particularly with respect to experienced mine construction and mine management personnel. As a result of this shortage, the wages that we are required to pay to our skilled workers have increased. In addition, employee turnover rates in the mining industry have increased as participants in the minerals industry compete for skilled personnel. Increased demand for services and equipment could result in delays if services or equipment cannot be obtained in a timely manner, and may cause scheduling difficulties due to the need to coordinate the availability of services or equipment, any of which could materially increase our project exploration and any future development and/or construction costs.

The price of silver, iszinc and lead are subject to change and a substantial or extended decline in the priceprices of silver, zinc or lead could materially and adversely affect our revenues and the value of our mineral properties.

Our business and financial performance will be significantly affected by fluctuations in the price of silver. The priceprices of silver, iszinc and lead. The prices of silver, zinc and lead are volatile, can fluctuate substantially and isare affected by numerous factors that are beyond our control. Since 2001,January 1, 2019 to August 31, 2020, the LBMA silver price of silver ranged from a low of $4.06$12.01 per ounce in November 2001on March 19, 2020 to a high of $48.44$28.33 per ounce inon August 7, 2020; the LME Official Settlement zinc price ranged from a low of $1,816 per

While1, 2019; the LME Official Settlement lead price ranged from a low of silver has increased significantly in recent years, such price movement is not$1,586 per tonne ($0.72 per pound) on March 24, 2020 to a predictorhigh of the future price of silver, which may decrease significantly as silver prices$2,265 per tonne ($1.03 per pound) on October 29, 2019. Prices are affected by numerous factors beyond our control, including:

    prevailing interest rates and returns on other asset classes;



expectations regarding inflation, monetary policy and currency values;



speculation;



governmental and exchange decisions regarding the disposal of precious metals stockpiles, including the decision by the CME Group, the owner and operator of the futures exchange, to raise silver’ssilver's initial margin requirements on futures contracts;



political and economic conditions;

demand for products containing silver.

silver, zinc and lead.

        Additionally, the COVID-19 pandemic and efforts to contain it, including restrictions on travel and other advisories issued may have a significant effect on silver, zinc and lead prices as well as demand. Because we expect to derive the substantial majority of our revenues from sales of silver, zinc and lead, our results of operations and cash flows will fluctuate as the price of silver increasesprices for these metals increase or decreases.decrease. A sustained period of declining silver prices would materially and adversely affect our financial performance, financial position and results of operations.

Changes in the future demand for the silver, zinc and lead we produce could adversely affect our future sales volume and revenues.

        Our future revenues will depend, in substantial part, on the volume of silver, zinc and lead we sell and the prices at which we sell, which in turn will depend on the level of industrial and consumer demand. Demand for silver is mostly driven by its general perception as a store of value as well as its uses in industrial processes and products, such as batteries, bearings, brazing and soldering, catalysts, electronics and photographic material, and its use by direct consumers, such as for jewelry, silverware and coins. See "Silver Industry Overview." An increase in the production of silver worldwide or changes in technology, industrial processes or consumer habits, including increased demand for substitute materials, may decrease the demand for silver. Increased demand for substitute materials may be either technologically induced, when technological improvements render alternative products more attractive for first-use or end-use than silver or allow for reduced application of silver, or price induced, when a sustained increase in the price of silver leads to partial substitution for silver by a less expensive product or reduced application of silver. Demand for zinc is primarily driven by the demand for galvanized steel, used in construction, automobile and other industrial applications. Demand for lead is primarily driven by the demand for batteries, used in vehicles, emergency systems and other industrial battery application. Any substitution of these materials may decrease the demand for the silver, zinc and lead we produce. A fall in demand, resulting from economic slow-downs or recessions or other factors, could also decrease the price and volume of silver, zinc and lead we sell and therefore materially and adversely impact our results of operations and financial condition.

We may fail to identify attractive acquisition candidates or joint ventures with strategic partners or may fail to successfully integrate acquired mineral properties or successfully manage joint ventures.

As part of our development strategy, we may acquire additional mineral properties or enter into joint ventures with strategic partners. However, there can be no assurance that we will be able to identify attractive acquisition or joint venture candidates in the future or that we will succeed at effectively managing their integration or operation. In particular, significant and increasing competition exists for mineral acquisition opportunities throughout the world. We face strong competition from other mining companies in connection with the acquisition of properties producing, or capable of producing, metals as well as in entering into joint ventures with other parties. If the expected synergies from such transactions do not materialize or if we fail to integrate them successfully into our existing business or operate them successfully with our joint venture partners, or if there are unexpected liabilities, our results of operations could be adversely affected.

        Pursuant to the Unanimous Omnibus Partner Agreement, we and Dowa must jointly approve of certain major decisions involving the LGJV, including decisions relating to the merger, amalgamation or restructuring of the LGJV and key strategic decisions, including with respect to expansion, among others. If we are unable to obtain the consent of Dowa, we may be unable to make decisions relating to the LGJV that we believe are beneficial for its operations, which may materially and adversely impact our results of operations and financial condition.

In connection with any future acquisitions or joint ventures, we may incur indebtedness or issue equity securities, resulting in increased interest expense or dilution of the percentage ownership of existing stockholders.shareholders. Unprofitable acquisitions or joint ventures, or additional indebtedness or issuances of securities in connection with such acquisitions or joint ventures, may adversely affect the price of our common stock and negatively affect our results of operations.

Our information technology systems may be vulnerable to disruption, which could place our systems at risk from data loss, operational failure or compromise of confidential information.

        We rely on various information technology systems. These systems remain vulnerable to disruption, damage or failure from a variety of sources, including, but not limited to, errors by employees or contractors, computer viruses, cyberattacks, including phishing, ransomware, and similar malware, misappropriation of data by outside parties, and various other threats. Techniques used to obtain unauthorized access to or sabotage our systems are under continuous and rapid evolution, and we may be unable to detect efforts to disrupt our data and systems in advance. Breaches and unauthorized access carry the potential to cause losses of assets or production, operational delays, equipment failure that could cause other risks to be realized, inaccurate recordkeeping, or disclosure of confidential information, any of which could result in financial losses and regulatory or legal exposure, and could have a material adverse effect on our cash flows, financial condition or results of operations. Although to date we have not experienced any material losses relating to cyberattacks or other information security breaches, there can be no assurance that we will not incur such losses in the future. Our risk and exposure to these matters cannot be fully mitigated because of, among other things, the evolving nature of these threats. As such threats continue to evolve, we may be required to expend additional resources to modify or enhance any protective measures or to investigate and remediate any security vulnerabilities.

We may be subject to claims and legal proceedings that could materially and adversely impact our financial position, financial performance and results of operations.

We may be subject to claims or legal proceedings covering a wide range of matters that arise in the ordinary course of business activities. These matters may result in litigation or unfavorable

resolution which could materially and adversely impact our financial performance, financial position and results of operations. See “Business—"Business—Legal Proceedings."

We are subject to the risk of labor disputes, which could adversely affect our business.

        Although we have not experienced any significant labor disputes in recent years, there can be no assurances that we will not experience labor disputes in the future, including protests, blockades and strikes, which could disrupt our business operations and have an adverse effect on our business and results of operation. Although we consider our relations with our employees to be good, there can be no assurance that we will be able to maintain a satisfactory working relationship with our employees in the future.

We have debt and may incur further debt in the future, which could adversely affect our financial health, limit our ability to obtain financing in the future and pursue certain business opportunities and reduce the value of your investment.

        The LGJV has debt service obligations pursuant to the agreements governing its outstanding debt. As of June 30, 2020, the LGJV had $222.8 million of debt outstanding under a term loan agreement with Dowa, dated July 11, 2017, as amended from time to time (the "Dowa Term Loan") and $60.0 million of debt outstanding under a working capital facility agreement with Dowa, dated May 30, 2019 (the "Los Gatos Working Capital Facility" and, together with the Dowa Term Loan, the "Dowa Debt Agreements"). In connection with entering into the Los Gatos Working Capital Facility, on April 16, 2019, we made a capital contribution to the LGJV of $18.2 million, which was used to repay a portion of another loan that the LGJV had with Dowa (the "MPR Loan") and Dowa agreed to convert the remaining balance under the MPR Loan in exchange for an approximate 18.5% of the equity interest of the LGJV, reducing our ownership in the LGJV to approximately 51.5%. For more information, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Dowa Debt Agreements."

        The Dowa Debt Agreements contain certain covenants and restrictions relating to the LGJV's use of the borrowings under such facilities, including: requiring the LGJV to use a substantial portion of funds from operations to make required payments of principal and interest, to retain certain levels of funds in reserve accounts and to accelerate repayment of the Dowa Term Loan for 70% of excess cash flows, as defined in the Dowa Debt Agreements. These covenants and restrictions will reduce funds available for operations and capital expenditures, future business opportunities, future dividends to us and other purposes; make the LGJV more vulnerable to economic and industry downturns and reduce flexibility in responding to changing business and economic conditions; limit flexibility in planning for, or reacting to, changes in the business and the industry in which we operate; place us at a competitive disadvantage compared to our competitors that have less debt; limit our ability to borrow more money for operations and sustaining capital or to finance acquisitions in the future; or require us to make future capital contributions to the LGJV, if needed, in order to make required payments of interest and principal. If we, as a 70.0% guarantor of the Dowa Term Loan and the Los Gatos Working Capital Facility, or the LGJV are unable to meet debt service obligations in the future, our financial position, financial performance and results of operations may be materially and adversely affected.

Our success depends on developing and maintaining relationships with local communities and stakeholders.

        Our ongoing and future success depends on developing and maintaining productive relationships with the communities surrounding our operations, including local indigenous people who may have rights or may assert rights to certain of our properties, and other stakeholders in our operating locations. We believe our operations can provide valuable benefits to surrounding communities in terms of direct employment, training and skills development and other benefits associated with ongoing payment of taxes. In addition, the purchase agreements entered into in connectionwe seek to maintain partnerships and relationships with local


Table of Contents

communities. Notwithstanding our ongoing efforts, local communities and stakeholders can become dissatisfied with our 2011 private placementsactivities or the level of benefits provided, which may result in legal or administrative proceedings, civil unrest, protests, direct action or campaigns against us. Any such occurrence could materially and adversely affect our business, financial condition or results of operations.

Our directors may have conflicts of interest as a result of their relationships with other mining companies.

        Our directors are also directors, officers and shareholders of other companies that are similarly engaged in the business of developing and exploiting natural resource properties. Consequently, there is a possibility that our directors may be in a position of conflict in the future.

Our business could be adversely affected by the effects of health epidemics, including the recent COVID-19 pandemic, in regions where we conduct our business operations.

        Our business could be adversely affected by health epidemics. For example, the outbreak of COVID-19 in the United States, Mexico and elsewhere has created significant business disruption and may adversely affect our business and operations. The outbreak has resulted in governments implementing numerous measures to contain COVID-19, such as travel bans and restrictions, particularly quarantines, shelter-in-place or total lock-down orders and business limitations and shutdowns. These containment measures are subject to change and the respective government authorities may tighten the restrictions at any time.

        In late March 2020, the Mexican government declared a national health emergency due to increasing infection rates from the COVID-19 pandemic. Pursuant to the health emergency declaration, the Mexican government ordered a temporary suspension of all "non-essential" operations nationwide in Mexico, including mining operations, in order to help combat the spread of COVID-19. In response to the order, the LGJV effected a 45-day temporary suspension of all non-essential activities at the Cerro Los Gatos Mine site, which reduced the number of employees and contractors at the site and the Chihuahua corporate office. During the temporary suspension, the LGJV implemented health protocols, allowed most administrative and technical services employees to work remotely, reduced mining and milling, completed project enhancements and finalized a mine plan upon reactivation of mining activities after the temporary suspension.

        In late May 2020, the Mexican government designated mining an essential service and allowed mines to resume production, subject to deploying COVID-19 prevention protocols. Our existing COVID-19 protocols exceeded those mandated by the Mexican government and, accordingly, the LGJV reactivated mine development and mining in late May 2020 and hired additional employees. Ore processing resumed in early June 2020. In order to maintain social distancing and best practice protocols, public areas, such as the residential camps' cafeterias, limited the number of personnel. Food service periods were extended with employees assigned specific times for meals. Face masks are required in offices and other public areas. Daily working shift times are staggered to limit the number of employees in changing areas and pre-shift work meetings. Two sterilization tunnels have been installed at the main entry gate and at the entrance to the cafeteria. All individuals entering the Cerro Los Gatos Mine site are subject to a seriesrapid test to screen for COVID-19 and, if an individual tests positive on the rapid test and on a secondary molecular test, the individual will be subject to quarantine protocols and removed from the mine site. In the event of investors, including Liberty Metals & Mining, contained customary indemnification provisions in favoran outbreak of COVID-19 on site, we could determine that a full suspension of our operations is necessary for the safety and protection of the investors.workers.

        The COVID-19 pandemic has temporarily affected our financial condition, in part due to the loss of revenue resulting from the 45-day temporary suspension of all non-essential activities at the LGJV's Cerro Los Gatos Mine site and the expenses associated with the development and implementation of


Table of Contents

COVID-19 protocols. In addition, as the LGJV reactivated mine development and mining, it implemented a scalable optimized plan with a lower employee complement and with reduced average monthly production rate at 1,750 tpd until September 2020, targeting higher ore grades. This may result in higher per tonne mining, processing and sustaining capital costs than previously anticipated. We intend to ramp up to the 2,500 tpd design capacity beginning in September 2020 with the goal of reaching the 2,500 tpd design capacity in January 2021.

        If the Mexican government were to reinstate the suspension order caused by the COVID-19 pandemic, or if all mining activities at the Cerro Los Gatos Mine site were suspended for an undefined period of time, there could be additional costs incurred, production and development delays, cost overruns and operational restart costs. In addition, given that our management travels regularly between Mexico City and the Cerro Los Gatos Mine site, any restrictions on travel within Mexico may adversely affect our management's ability to oversee ongoing mining activities at the Cerro Los Gatos Mine and our ability to achieve our business objectives and milestones.

        We may take further actions as may be required by government authorities or as we determine are in the best interests of our employees and business partners. There is no guarantee that we will not experience significant disruptions to or additional closures of some or all of our operations in the future. Such modifications to our business practices may negatively impact productivity, divert resources away from or otherwise disrupt our or the LGJV's business operations and delay and disrupt exploration and production timelines. Any long term closures or suspensions may also result in the loss of personnel or the workforce in general as employees seek employment elsewhere.

        While the full impact of this pandemic is unknown at this time, we are closely monitoring the rapid developments of the outbreak and continually assessing the potential impact on our business. Any prolonged disruption of our or the LGJV's operations and closures of facilities would delay our current exploration and production timelines and negatively impact our business, financial condition and results of operations. There are no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have, and, as a result, the ultimate impact of the outbreak is highly uncertain and subject to change. However, the COVID-19 pandemic could have a material adverse effect on our business, financial condition and results of operations and heighten many of our known risks described in this "Risk Factors" section.

Risks Related to Government Regulations and International Operations

The U.S. and Mexican governments,government, as well as state and local governments, extensively regulate mining operations, which imposesimpose significant actual and potential costs on us, and future regulation could increase those costs, delay receipt of regulatory refunds or limit our ability to produce silver and other metals.

The mining industry is subject to increasingly strict regulation by federal, state and local authorities in the United States and Mexico, including in relation to:

    limitations on land use;



mine permitting and licensing requirements;



reclamation and restoration of properties after mining is completed;



management of materials generated by mining operations; and



storage, treatment and disposal of wastes and hazardous materials.

    Table of Contents

    The liabilities and requirements associated with the laws and regulations related to these and other matters, including with respect to air emissions, water discharges and other environmental matters, may be costly and time-consuming and may restrict, delay or prevent commencement or continuation of exploration or production operations. We cannot assure you that we have been or will be at all times in compliance with all applicable laws and regulations. Failure to comply with applicable laws and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of cleanup and site restoration costs and liens, the issuance of injunctions to limit or cease operations, the suspension or revocation of permits or authorizations and other enforcement measures that could have the effect of limiting or preventing production from our operations.

    We may incur material costs and liabilities resulting from claims for damages to property or injury to persons arising from our operations. If we are pursued for sanctions, costs and liabilities in respect of these matters, our mining operations and, as a result, our financial performance, financial position and results of operations, could be materially and adversely affected. See “Business—"Business—Environmental, Health and Safety Measures.”Matters."

    Any new legislation or administrative regulations or new judicial interpretations or administrative enforcement of existing laws and regulations that would further regulate and tax the mining industry may also require us to change operations significantly or incur increased costs. Such changes could have a material adverse effect on our financial performance, financial position and results of operations.

    In addition, the operation of our Sunshine Mine in the United States is subject to regulation by the Federal Mine Safety and Health Administration, or the MSHA, under the Federal Mine Safety and Health Act of 1977 and the Occupational Safety and Health Administration, or the OSHA, under the Occupational Safety and Health Act of 1970. MSHA and OSHA inspect the Sunshine Mine on a regular basis and issue various citations and orders when they believe a violation has occurred under the relevant statute. Subsequent to passage of the Mine Improvement and New Emergency Response Act of 2006, the number of violations cited by the MSHA has significantly increased, as have the dollar penalties associated with those citations.

    Our        The Mexican properties are subject to regulation by the Political Constitution of the Mexican United States, and are subject to various legislation in Mexico, including the Mining Law, the Federal Law of Waters, the Federal Labor Law, the Federal Law of Firearms and Explosives, the General Law on Ecological Balance and Environmental Protection and the Federal Law on Metrology Standards. Our operations at ourthe Mexican properties also require us to obtain local authorizations and, under the Agrarian Law, to comply with the uses and customs of communities located within the properties. Mining, environmental and labor authorities may inspect our Mexican operations on a regular basis and issue various citations and orders when they believe a violation has occurred under the relevant statute.

    If inspections in the United States or Mexico result in an alleged violation, we may be subject to fines, penalties or sanctions, our mining operations could be subject to temporary or extended closures, and we may be required to incur capital expenditures to re-commence our operations. Any of these actions could have a material adverse effect on our financial performance, financial position and results of operations.

            In late March 2020, in response to the COVID-19 pandemic, the Mexican government ordered a temporary suspension of all "non-essential" operations nationwide in Mexico, including mining operations. In late May 2020, the Mexican government designated mining an essential service and allowed mines to resume production, subject to deploying COVID-19 prevention protocols. However, there is no certainty that the Mexican regulators will not require further limitations on, or even a full shut down of, the operations at the Cerro Los Gatos Mine in connection with COVID-19. The potential costs of complying with these COVID-19 requirements is unknown and could have a material adverse effect on us.

    Our Mexican operations are subject to additional political, economic and other uncertainties not generally associated with domesticU.S. operations.

    We currently have a significant exploration projecttwo properties in Mexico,Mexico: the Los Gatos Project, along with 19 other exploration properties inDistrict, which the country,LGJV controls, and the Santa Valeria property, which we control. Our operations are subject to significant risks inherent in exploration and resource extraction by foreign companies in Mexico. Exploration, development, production and closure activities in Mexico are potentially subject to heightened political, economic, regulatory and social risks that are beyond our control. These risks include:

      the possible unilateral cancellation or forced re-negotiation of contracts;

    contracts and licenses;

    unfavorable changes in laws and regulations;

    Table of Contents

      royalty and tax increases;



    claims by governmental entities or indigenous communities;



    expropriation or nationalization of property;



    political instability;



    fluctuations in currency exchange rates;

    social and labor unrest, organized crime, hostage taking, terrorism and violent crime;

    uncertainty regarding the enforceability of contractual rights and judgments; and



    other risks arising out of foreign governmental sovereignty over areas in which our mineral properties are located.

    Local economic conditions also can increase costs and adversely affect the security of our operations and the availability of skilled workers and supplies. Higher incidences of criminal activity and violence in the area of some of our properties could adversely affect ourthe LGJV's ability to operate in an optimal fashion or at all. Recently, we cancelledall, and may impose greater risks of theft and higher costs, which would adversely affect results of operations and cash flows.

            Acts of civil disobedience are common in Mexico. In recent years, many mining companies have been targets of actions to restrict their legally-entitled access to mining concessions or property. Such acts of civil disobedience often occur with no warning and can result in significant direct and indirect costs. We cannot provide assurance that there will be no disruptions to site access in the Niko concession, a Mexican property outside the Los Gatos region, due to ongoing gang violence, and we terminated the project.future, which could adversely affect our business.

    Additionally, the        The right to export silver-bearing concentrate and other metals may depend on obtaining certain licenses, which could be delayed or denied at the discretion of the relevant regulatory authorities, or meeting certain quotas. Furthermore, the United States has recently instituted or proposed other changes in trade policies that include the negotiation or termination of trade agreements, including free trade agreements, economic sanctions on individuals, corporations or countries, and other government regulations affecting trade between the United States and other countries. It may be time-consuming and expensive for us to alter our operations in order to adapt to or comply with any such changes. If the United States were to withdraw from or materially modify international trade agreements to which it is a party, or if other countries imposed or increased tariffs on the minerals we may extract in the future, the costs of such products could increase significantly. Any of these conditions could lead to lower productivity and higher costs, which would adversely affect our financial performance, financial position and results of operations. Generally, our operations may be affected in varying degrees by changing government regulations in the United States and/or Mexico with respect to, but not limited to, restrictions on production, price controls, export controls, currency remittance, importation of products and supplies, income and other taxes, royalties, the repatriation of profits, expropriation of mineral property, foreign investment, maintenance of concessions, licenses, approvals and permit, environmental matters, land use, land claims of local indigenous people and workplace safety.

    Any of these        Such developments could require us to curtail or terminate operations at our mineral properties in Mexico, incur significant costs to meet newly-imposed environmental or other standards, pay greater royalties or higher prices for labor or services and recognize higher taxes, which could materially and adversely affect our results of operations, cash flows and financial condition. Furthermore, failure to comply strictly with applicable laws, regulations and local practices could result in loss, reduction or expropriation of licenses, or the imposition of additional local or foreign parties as joint venture partners with carried or other interests.

            We continue to monitor developments and policies in Mexico and assess the impact thereof on our operations; however, such developments cannot be accurately predicted and could have an adverse effect on our business, financial condition and results of operations.

    We are required to obtain, maintain and renew environmental, construction and mining permits, which is often a costly and time-consuming process.process and may ultimately not be possible.

    Mining companies, including ours, need many environmental, construction and mining permits, each of which can be time-consuming and costly to obtain, maintain and renew. In connection with our current and future operations, we must obtain and maintain a number of permits that impose strict conditions, requirements and obligations, including those relating to various environmental and health and safety matters. To obtain, maintain and renew certain permits, we have been and may in the future be required to conduct environmental studies, and make associated presentations to governmental authorities, pertaining to the potential impact of our current and future operations upon the environment and to take steps to avoid or mitigate those impacts. Permit terms and conditions can impose restrictions on how we conduct our operations and limit our flexibility in developing our mineral properties. Many of our permits are subject to renewal from time to time, and applications for renewal may be denied or the renewed permits may contain more restrictive conditions than our existing permits, including those governing impacts on the environment. For example, we may be required to upgrade our wastewater treatment system in connection with the renewal of our National Pollutant Discharge Elimination System, or NPDES, permit for the Sunshine Mine. In addition, weWe may be required to obtain new permits to expand our operations, and the grant of such permits may be subject to an expansive governmental review of our operations. Alternatively, weWe may not be successful in obtaining such permits, which could prevent us from commencing, continuing or expanding operations or otherwise adversely affect our business. Renewal of existing permits or obtaining new permits may be more difficult if we are not able to comply with our existing permits. Applications for permits, permit area expansions and permit renewals can also be subject to challenge by interested parties, which can delay or prevent receipt of needed permits. In addition, theThe permitting process can vary by jurisdiction in terms of its complexity and likely outcomes. The applicable laws and regulations, and the related judicial interpretations and enforcement policies, change frequently, which can make it difficult for us to obtain and renew permits and to comply with applicable requirements. Accordingly, permits required for our operations may not be issued, maintained or renewed in a timely fashion or at all, may be issued or renewed upon conditions that restrict our ability to conduct our operations economically, or may be subsequently revoked. Any such failure to obtain, maintain or renew permits, or other permitting delays or conditions, including in connection with any environmental impact analyses, could have a material adverse effect on our business, results of operations and financial condition.

    In addition, in regardsregard to the Cerro Los Gatos Mine, the Los Gatos ProjectDistrict and other Mexican projects, Mexico has adopted laws and guidelines for environmental permitting that are similar to those in effect in the United States and South American countries. We are currently operating under permits regulating road constructionmining, processing, use of explosives, water use and drilling at our El Doctor, Los Gatos, Mina Grandedischarge and Zacatlan projects contingent upon paying annual fees and providing annual reports, which cover the work accomplished on the property,surface disturbance in relation to the Mexican government. We are also preparing a larger scale permit at the Los Gatos Project which requires a detailed environmental assessmentDistrict and impact study for the future possibility of establishing underground access for further exploration. There can be no certainty as to whether, or the terms under which, such permit will be granted. In addition, weSanta Valeria property. We will be required to

    apply for corresponding authorizations prior to any production at each of our other Mexican properties and there can be no certainty as to whether, or the terms under which, such authorizations will be granted or renewed. Any failure to obtain authorizations and permits, or other authorization or permitting delays or conditions, could have a material adverse effect on our business, results of operations and financial condition.

    We are subject to environmental and health and safety laws, regulations and permits that may subject us to material costs, liabilities and obligations.

    We are subject to environmental laws, regulations and permits in the various jurisdictions in which we operate, including those relating to, among other things, the removal and extraction of natural resources, the emission and discharge of materials into the environment, including greenhouse gas emissions, plant and wildlife


    Table of Contents

    protection, remediation of soil and groundwater contamination, reclamation and closure of properties, including tailings and waste impoundments,storage facilities, groundwater quality and availability, and the handling, storage, transport and disposal of wastes and hazardous materials. Pursuant to such requirements, we may be subject to inspections or reviews by governmental authorities. Failure to comply with these environmental requirements may expose us to litigation, fines or other sanctions, including the revocation of permits and suspension of operations. We expect to continue to incur significant capital and other compliance costs related to such requirements. These laws, regulations and permits, and the enforcement and interpretation thereof, change frequently and generally have become more stringent over time. If our noncompliance with such regulations were to result in a release of hazardous materials into the environment, such as soil or groundwater, we could be required to remediate such contamination, which could be costly. Moreover, noncompliance could subject us to private claims for property damage or personal injury based on exposure to hazardous materials or unsafe working conditions. In addition, changes in applicable requirements or stricter interpretation of existing requirements may result in costly compliance requirements or otherwise subject us to future liabilities. The occurrence of any of the foregoing, as well as any new environmental, health and safety laws and regulations applicable to our business or stricter interpretation or enforcement of existing laws and regulations, could have a material adverse effect on our business, financial condition and results of operations.

    We could be liable for any environmental contamination at, under or released from our or our predecessors’predecessors' currently or formerly owned or operated properties or third-party waste disposal sites, including the Bunker Hill Superfund Site.sites. Certain environmental laws impose joint and several strict liability for releases of hazardous substances at such properties or sites, without regard to fault or the legality of the original conduct. A generator of waste can be held responsible for contamination resulting from the treatment or disposal of such waste at any off-site location (such as a landfill), regardless of whether the generator arranged for the treatment or disposal of the waste in compliance with applicable laws. Costs associated with liability for removal or remediation of contamination or damage to natural resources could be substantial and liability under these laws may attach without regard to whether the responsible party knew of, or was responsible for, the presence of the contaminants. Accordingly, we may be held responsible for more than our share of the contamination or other damages, up to and including the entire amount of such damages. In addition to potentially significant investigation and remediation costs, such matters can give rise to claims from governmental authorities and other third parties, including for orders, inspections, fines or penalties, natural resource damages, personal injury, property damage, toxic torts and other damages.

    Our costs, liabilities and obligations relating to environmental matters could have a material adverse effect on our financial performance, financial position and results of operations.

    Legislation has previously been proposed that would significantly affect the mining industry.We may be responsible for anti-corruption and anti-bribery law violations.

    Periodically, members        Our operations are governed by, and involve interactions with, various levels of government in foreign countries. We are required to comply with anti-corruption and anti-bribery laws, including the Corruption of Foreign Public Officials Act (Canada) and the U.S. Congress have introduced bills which would supplantForeign Corrupt Practices Act (the "FCPA") and similar laws in Mexico. These laws generally prohibit companies and company employees from engaging in bribery or alterother prohibited payments to foreign officials for the provisionspurpose of obtaining or retaining business. The FCPA also requires companies to maintain accurate books and records and internal controls. Because our interests are located in Mexico, there is a risk of potential FCPA violations.

            In recent years, there has been a general increase in both the U.S. General Mining Lawfrequency of 1872, which governsenforcement and the unpatented claimsseverity of penalties under such laws, resulting in greater scrutiny and punishment to companies convicted of violating anti-corruption and anti-bribery laws.

    procedures and programs may not always be effective in ensuring that we, controlour employees, contractors or third-party agents will comply strictly with all such applicable laws. If we become subject to an enforcement action or we are found to be in violation of such laws, this may have a material adverse effect on our reputation and may possibly result in significant penalties or sanctions, and may have a material adverse effect on our cash flows, financial condition or results of operations.

    We may be required by human rights laws to take actions that delay our operations or the advancement of our projects.

            Various international and national laws, codes, resolutions, conventions, guidelines and other materials relate to human rights (including rights with respect to health and safety and the Sunshine Mine.environment surrounding our operations). Many of these materials impose obligations on government and companies to respect human rights.

The obligations of government and private parties under the various international and national materials pertaining to human rights continue to evolve and be defined.

Such opposition may be directed through legal or administrative proceedings or expressed in manifestations such as thoseprotests, roadblocks or other forms of public expression against our activities, and may have a negative impact on our reputation. Opposition by such groups to our operations may require modification of, or preclude the Sunshine Mine property. Other bills have proposed, among other things, to make permanent the patent moratorium, to impose a federal royalty on production from unpatented mining claims and to declare certain lands as unsuitable for mining. If additional legislation is enacted, it could substantially increase the cost of holding unpatented mining claims by requiring payment of royalties, and could significantly impair our ability to develop mineral estimates on unpatented mining claims. Although it is impossible to predict at this time what royalties may be imposed in the future, the imposition of such royalties could adversely affect the potential foroperation or development of, our projects or may require us to enter into agreements with such mining claims.

    Risks Related to thisThis Offering and ourOur Common Stock

    There is no existing market for our common stock and we do not know if one will develop. Even if a market does develop, the stock price in the market may not exceed the offering price.

    Prior to this offering, there has not been a public market for our common stock. We cannot predict the extent to which investor interest in our Company will lead to the development of an active trading market on the

    New York Stock Exchange, NYSE, the Toronto Stock ExchangeTSX or otherwise, or how liquid that market may become. An active trading market for our common stock may not develop and even if it does develop, may not continue upon the completion of this offering and the market price of our common stock may decline below the initial public offering price. The initial public offering price for the common stock will be determined by negotiations between us and the representatives of the underwriters and may not be indicative of prices that will prevail in the open market following this offering. Consequently, you may not be able to sell shares of our common stock at prices equal to or greater than the price you pay in this offering.

    The market price of our common stock may be volatile, which could result in substantial losses for you.

    The initial public offering price for our common stock will be determined through negotiations between us and the representatives of the underwriters. This initial public offering price may vary from the market price of our common stock after this offering. Some of the factors that may cause the market price of our common stock to fluctuate include:

      failure to identify mineral reserves at our properties;



    failure to achieve production at our mineral properties;



    actual or anticipated changes in the price of silver and base metal by-products;



    fluctuations in our quarterly and annual financial results or the quarterly and annual financial results of companies perceived to be similar to us;

    Table of Contents

      changes in market valuations of similar companies;



    success or failure of competitor mining companies;



    changes in our capital structure, such as future issuances of securities or the incurrence of debt;



    sales of large blocks of our common stock;



    announcements by us or our competitors of significant developments, contracts, acquisitions or strategic alliances;



    changes in regulatory requirements and the political climate in the United States, Mexico or both;



    litigation involving our Company, our general industry or both;



    additions or departures of key personnel;

    investors’

    investors' general perception of us, including any perception of misuse of sensitive information;



    changes in general economic, industry and market conditions;



    accidents at mining properties, whether owned by us or otherwise;



    natural disasters, terrorist attacks and acts of war; and



    our ability to control our costs.

    In addition, if        If the market for stocks in our industry, or the stock market in general, experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, financial condition or results of operations. These and other factors may cause the market price and demand for our common stock to fluctuate substantially, which may limit or prevent investors from readily selling their shares of common stock and may otherwise negatively affect the liquidity of our common stock. In the past, when the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of our shareholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. Such a lawsuit could also divert the time and attention of our management from our business.

    If any of the foregoing occurs, it could cause our stock price to fall and may expose us to lawsuits that, even if unsuccessful, could be both costly to defend against and a distraction to management.

    Our anti–takeoveranti-takeover defense provisions may cause our common stock to trade at market prices lower than it might absent such provisions.

    Our Board of Directors has the authority to issue blank check preferred stock. Additionally, our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws that we will adopt prior to the

    closing of this offering will contain several provisions that will apply after Electrum, or any person which is an express assignee or designee of Electrum, ceases to own in the aggregate more than 50% of our outstanding common stock. These provisions may make it more difficult or expensive for a third party to acquire control of us without the approval of our Board of Directors. These provisions include provisions that setsetting forth advance notice procedures for stockholders’shareholders' nominations of directors and proposals of topics for consideration at meetings of stockholders,shareholders, provisions restricting stockholdersshareholders from calling a special meeting of stockholdersshareholders or requiring one to be called, provisions limiting the ability of stockholdersshareholders to act by written consent and provisions requiring a 66 2/3% stockholder66.67% shareholder vote to amend our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws and a staggered board. Our Amended and Restated Certificate of Incorporation will also provide that Section 203 of the Delaware General Corporation Law, or DGCL, which relates to business combinations with interested stockholders, will not apply to us until such time as Electrum ceases to own more than 50% of our outstanding common stock, after which time we will be governed by those provisions.Bylaws. These provisions may delay, prevent or deter a merger, acquisition, tender offer, proxy contest or other transaction that might otherwise result in our stockholdersshareholders receiving a premium over the market price for their common stock. In addition, these provisions may cause our common stock to trade at a market price lower than it might absent such provisions.

    You will suffer immediate and substantial dilution as a result of this offering.

    The initial public offering price per share of our common stock is substantially higher than our net tangible book value per share immediately after this offering. As a result, if you purchase shares in this offering, you will pay a price per share that substantially exceeds the book value of our assets after subtracting our liabilities.liabilities, and any additional financing in the future may cause further dilution to our existing shareholders and there can be no assurance that any future additional financing will be on terms that are favorable to us or our shareholders. At an offering price of $            per share, which is the midpoint of the offering price range set forth on the front cover of this prospectus, you will incur immediate and substantial dilution of your investment in the amount of $            per share. See “Dilution.”"Dilution."

    Future sales of our common stock after the lock-up period has expired, or the perception that such sales may occur, could depress our common stock price.

    After this offering, we will have                        shares of common stock outstanding.outstanding (or                        shares of common stock outstanding if the underwriters' over-allotment option is exercised in full). This includes the shares of common stock we are selling in this offering, which may generally be resold in the public market immediately after this offering. We expect that the remaining shares of common stock, representing        % of our total outstanding shares of common stock following this offering, will become available for resale in the public market as set forth under the heading “Shares"Shares Eligible for Future Sale." All of our directors and executive officers, and the holders of substantially all of our common stock, have signed lock-up agreements for a period of 180 days following the date of this prospectus, subject to extension in the case of an earnings release or material news or a material event relating to us. Morgan StanleyBMO Capital Markets Corp., Goldman Sachs & Co. LLC and RBC Capital Markets, LLC may, in itstheir sole discretion and without notice, release all or any portion of the common stock subject to lock-up agreements. There are no agreements, understandings or intentions, tacit or explicit, to release any of the common stock subject to lock-up agreements prior to the expiration of the lock-up period. As restrictions on resale end, the market price of our common stock could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them, and we will enter into a registration rights agreement with substantially all our stockholdersshareholders in connection with this offering. See “Certain"Certain Relationships and Related Party Transactions—Registration Rights Agreement." These factors could also make it more difficult for us to raise additional funds through future offerings of our common stock or other securities.

    In addition, immediately following this offering, we intend to file a registration statement registering under the United States Securities Act of 1933, or theas amended (the "U.S. Securities Act,Act"), the shares of common stock reserved for issuance in respect of incentive awards to our directors and certain of our employees. This would result in approximately                         shares of common stock underlying options vested as of the date of this prospectus beingsuch awards becoming available for resale intoin the public markets, after the expiration ofsubject to any applicable lock-up agreements to which substantially all of those shares are subject.agreements.

    We do not currently intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

    We have never declared or paid any cash dividend on our capital stock. We do not intend to pay any cash dividends on our common stock for the foreseeable future. We currently intend to retain all future earnings, if any, to finance our business. The payment of any future dividends, if any, will be determined by our Board of Directors in light of conditions then existing, including our earnings, financial condition and capital requirements, business conditions, corporate law requirements and other factors. See “Dividend"Dividend Policy."


    Certain non-U.S. investors may be subject to U.S. income tax with respect to gain on dispositionsTable of our common stock if we are or become a U.S. real property holding corporation.Contents

    Based on our estimates of the current relative fair market values of our U.S. real property interests and other assets, we believe that we are not currently a U.S. real property holding corporation, or a USRPHC, for U.S. federal income tax purposes. However, both because the determination of the value of our mineral assets is uncertain and requires the use of subjective estimates, and because the relative fair market values of our assets will likely fluctuate over time (based on, for example, the results of the exploration and development of our properties), there can be no assurance that we are not, or will not become, a USRPHC. If we are or have been a USRPHC, certain non-U.S. investors will generally be subject to U.S. federal income tax on gain realized on a sale or other disposition of our common stock. However, for so long as our common stock is regularly traded on an established securities market (such as the New York Stock Exchange), a non-U.S. investor will not recognize taxable gain on a sale of our common stock under the rules applicable to USRPHCs unless the investor actually or constructively owns more than 5% of our common stock at any time during the five-year period ending on the date of disposition or, if shorter, its holding period for our common stock. See “U.S. Federal Tax Considerations for Non-U.S. Holders of Common Stock—Gain on Disposition of Common Stock.”

    Electrum, Liberty Metals & MiningMERS and their respective affiliates will continue to have a substantial degree of control over us after this offering, which could delay or prevent a change of corporate control or result in the entrenchment of our management and/or the Board of Directors.

    After this offering, Electrum will beneficially own, in the aggregate, approximately        % of our outstanding common stock (approximately        % if the underwriters’underwriters' over-allotment option is exercised in full). In addition, following this offering Liberty Metals & Miningand assuming no exercise by the underwriters of their over-allotment option, MERS will beneficially own, in the aggregate, approximately        % of our outstanding common stock (approximately        % if the underwriters’underwriters' over-allotment option is exercised in full). In connection with this offering, we willintend to enter into a stockholdersshareholders agreement with Electrum and Liberty Metals & MiningMERS pursuant to which Electrum and Liberty Metals & MiningMERS will have certain director nomination rights. The stockholders agreementsshareholders agreement will also provide that Electrum approval must be obtained prior to us engaging in certain actions. See “Certain"Certain Relationships and Related Party Transactions—StockholdersShareholders Agreement." As a result, Electrum will have the ability to control theour management and affairs of our Company and will have control over the outcome of matters submitted to our stockholdersshareholders for approval, including the election and removal of directors and any merger, consolidation or sale of all or substantially all of our assets.

    Our concentration of ownership and stockholdersshareholders agreement may harm the market price of our common stock by, among other things:

      delaying, deferring or preventing a change of control, even at a per share price that is in excess of the then-current price of our common stock;



    impeding a merger, consolidation, takeover or other business combination involving us, even at a per share price that is in excess of the then-current price of our common stock; or



    discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of us, even at a per share price that is in excess of the then current price of our common stock.

    Our relationship with SOP may strain our senior management resources and could potentially result in conflicts of interest.

            Immediately prior to the closing of this offering, we intend to effect the Reorganization. See "Prospectus Summary—Corporate Information and Reorganization." In addition, we intend to enter into a Management Services Agreement with SOP, pursuant to which we will provide certain executive and managerial advisory services to SOP. See "Certain Relationships and Related Party Transactions—Reorganization and Management Services Agreement." SOP will reimburse us for costs representing the proportion of our advisory services allocated to it under the Management Services Agreement. However, providing such advisory services to SOP may strain our resources and divert management's attention from our principal projects and other business concerns, which would adversely affect our business and operating results. We anticipate that at least some of our directors will also be directors of SOP, which could create, or appear to create, conflicts of interest with respect to matters involving both us and SOP.

    The requirements of being a public company may strain our resources, divert management’smanagement's attention and affect our ability to attract and retain executive management and qualified board members.members, which could make it difficult to manage our business, particularly after we are no longer an "emerging growth company."

            Following the completion of this offering, we will be required to comply with various regulatory and reporting requirements, including those required by the Securities and Exchange Commission (the "SEC"). Complying with these reporting and other regulatory requirements will be time-consuming and


    Table of Contents

    will result in increased costs to us and could have a negative effect on our business, financial condition and results of operations.

    As a public company, we will be subject to the reporting requirements of the Securities Exchange Act of 1934, or the Exchange Act, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, the Dodd-Frank Act, applicable Canadian securities laws and regulations, the listing requirements of the New York Stock ExchangeNYSE and the Toronto Stock ExchangeTSX and other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources, particularly after we are no longer an “emerging"emerging growth company." The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controlcontrols over financial reporting. In order to maintain and, if required, improve the effectiveness of our disclosure controls and procedures and internal controlcontrols over financial reporting to meet this standard, we will need to commit significant resources, hire additional staff and provide additional management oversightoversight. We will be implementing additional procedures and processes for the purpose of addressing the standards and requirements applicable to public companies. Sustaining our growth also will require us to commit additional management, operational and financial resources to identify new professionals to join us and to maintain appropriate operational and financial systems to adequately support expansion. These activities may be required. As a result, management’sdivert management's attention may be diverted from other business concerns, which could adversely affect our business and operating results.

    For as long as we remain        As an “emerging"emerging growth company”company" as defined in the JOBS Act, we mayintend to take advantage of certain temporary exemptions from various reporting requirements, that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. When these exemptions cease to apply, we expect to incur additional expenses and devote increased management effort toward ensuring compliance with them. We cannot predict or estimate the amount of additional costs we may take advantageincur as a result of these reporting exemptions until we are no longer an “emerging growth company.”becoming a public company or the timing of such costs.

    We will remain an “emerging"emerging growth company” for upcompany" until the earliest of: (i) the last day of the first fiscal year in which our annual gross revenues are $1.07 billion or more; (ii) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt securities; or (iii) the date on which we are deemed to five years, although ifbe a "large accelerated filer," which will occur as of the end of any fiscal year in which we (x) have an aggregate market value of our common stock that is held by non-affiliates exceedsof $700 million as of any June 30 before that time, we would cease to be an “emerging growth company”or more as of the following January 31.last business day of our most recently completed second fiscal quarter, (y) have been required to file annual and quarterly reports under the Exchange Act, for a period of at least 12 months and (z) have filed at least one annual report pursuant to the Exchange Act.

    We also expect that being a public company and complying with these new rules and regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee and compensation and nominating committee, and qualified executive officers.

    As a result of disclosure of information in this prospectus and in filings required of a public company, our business and financial condition will become more visible, which we believe may result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business and operating results could be adversely affected, and even if the claims do not


    Table of Contents

    result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and adversely affect our business and operating results.

    As a result of becoming a public company, we will be obligated to develop and maintain proper and effective internal controlcontrols over financial reporting. We may not complete our analysis of our internal controlcontrols over financial reporting in a timely manner, or these internal controls may not be determined to be effective, which may adversely affect investor confidence in our companyus and, as a result, the value of our common stock.

    We may be required, pursuant to Section 404 of the Sarbanes–OxleySarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal controlcontrols over financial reporting for the first fiscal year beginning after the effective date of this offering. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal controlcontrols over financial reporting, as well as a statement that our independent registered public accounting firm has issued an opinion on our internal controlcontrols over financial reporting.

    We are in the very early stages of the costly and challenging process of compiling the system and processing documentation necessary to perform the evaluation needed to comply with Section 404. We may not be able to complete our evaluation, testing and any required remediation in a timely fashion. During the evaluation and testing process, if we identify one or more material weaknesses in our internal controlcontrols over financial reporting, we will be unable to assert that our internal controls are effective.

    If we are unable to assert that our internal controlcontrols over financial reporting isare effective, or if our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal controls, we could lose investor confidence in the accuracy and completeness of our financial reports, which wouldcould cause the price of our common stock to decline, and we may be subject to investigation or sanctions by the SEC.

            

    We will be required to disclose changes made in our internal controlcontrols and procedures on a quarterly basis. However, our independent registered public accounting firm will not be required to formally attest to the effectiveness of our internal controlcontrols over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act until the later of the year following our first annual report required to be filed with the SEC and the date we are no longer an “emerging"emerging growth company”company" as defined in the JOBS Act, if we take advantage of the exemptions contained in the JOBS Act. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. Our remediation efforts may not enable us to avoid a material weakness in the future. We will remain an “emerging"emerging growth company”company" for up to five years, although if the market value of our common stock that is held by non-affiliates exceeds $700 million as of any                  before that time, we would cease to be an “emerging growth company” as of the following January 31.years. To comply with the requirements of being a public company, we may need to undertake various actions, such as implementing new internal controls and procedures and hiring additional accounting or internal audit staff.

    We are an “emerging"emerging growth company”company" and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

    We are an “emerging"emerging growth company," as defined in the JOBS Act, and we mayintend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging"emerging growth companies”companies" including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common stock less attractive if we rely on these exemptions. If


    Table of Contents

    some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

            Even after we no longer qualify as an emerging growth company, we may still qualify as a "smaller reporting company," which would allow us to take advantage of many of the same exemptions from disclosure requirements including reduced disclosure obligations regarding executive compensation in this prospectus and our periodic reports and proxy statements. We would also be exempt from the requirement to obtain an external audit on the effectiveness of internal control over financial reporting provided in Section 404(b) of the Sarbanes-Oxley Act. These exemptions and reduced disclosures in our SEC filings due to our status as a smaller reporting company mean our auditors do not review our internal control over financial reporting and may make it harder for investors to analyze our results of operations and financial prospects. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock prices may be more volatile.

    Our Amended and Restated Certificate of Incorporation and stockholdersshareholders agreement will contain a provision renouncing our interest and expectancy in certain corporate opportunities.

    Our Amended and Restated Certificate of Incorporation and stockholdersshareholders agreement provideswill provide for the allocation of certain corporate opportunities between us and Electrum and Liberty Metals & Mining.MERS. Under these provisions, neither Electrum or Liberty Metals & Mining,nor MERS, their affiliates and subsidiaries, nor any of their officers, directors, agents, stockholders, members or partners will have any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which we operate. For instance, a director of our Company who is not employed by usalso our employee and also serves as a director, officer or employee of Electrum or Liberty Metals & MiningMERS or any of their subsidiaries or affiliates may pursue certain acquisition or other opportunities that may be complementary to our business and, as a result, such acquisition or other opportunities may not be available to us. These potential conflicts of interest could have a material adverse effect on our financial performance, financial position and results of operations if attractive corporate

    opportunities are allocated by Electrum or Liberty Metals & MiningMERS to themselves or their subsidiaries or affiliates instead of to us. The terms of our Amended and Restated Certificate of Incorporation are more fully described in “Description"Description of Capital Stock”Stock" and the terms of our stockholdersshareholders agreement are more fully described in “Certain"Certain Relationships and Related Party Transactions—StockholdersShareholders Agreement."

    Our Amended and Restated Certificate of Incorporation will provide that the Court of Chancery of the State of Delaware and the federal district courts of the United States are the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

            Our Amended and Restated Certificate of Incorporation will provide that the Court of Chancery of the State of Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law:

      any derivative action or proceeding brought on our behalf;

      any action asserting a breach of fiduciary duty;

      any action asserting a claim against us arising under the Delaware General Corporation Law; and

      any action asserting a claim against us that is governed by the internal affairs doctrine.

            This provision does not apply to suits brought to enforce a duty or liability created by the Securities Act, the Exchange Act or any other claim for which the U.S. federal courts have exclusive


    Table of Contents

    jurisdiction. Our Amended and Restated Certificate of Incorporation will further provide that the federal district courts of the United States will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.

            Our Amended and Restated Certificate of Incorporation will also provide that any person or entity purchasing or otherwise acquiring or holding any interest in shares of our capital stock will be deemed to have notice of and to have consented to these choice of forum provisions. These exclusive forum provisions may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers, and other employees, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder.

            While Delaware courts have determined that choice of forum provisions are facially valid, it is possible that a court of law in another jurisdiction could rule that the choice of forum provisions to be contained in our Amended and Restated Certificate of Incorporation are inapplicable or unenforceable if they are challenged in a proceeding or otherwise. If a court were to find the choice of forum provision in our Amended and Restated Certificate of Incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions.

    We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

            We currently intend to use the net proceeds from this offering in the manner described in "Use of Proceeds." However, our Board of Directors and management will retain broad discretion in the application, and timing of the application, of the net proceeds from this offering and could spend the net proceeds in ways that do not improve our results of operations or enhance the value of our common stock. As such, we may use net proceeds of this offering in ways that an investor may not consider desirable, if our Board of Directors and management believe such use would be in our best interest. As a result, investors will be relying on the judgment of our Board of Directors and management for the application of the net proceeds from this offering. There can be no assurance regarding the results and the effectiveness of our use of the net proceeds from this offering. Our failure to apply these funds effectively could result in financial losses that could harm our business, cause the market price of our stock to decline, and delay the development of our operations.

      Overview

      Sunshine Silver Mines Corporation is        We are a U.S.-based precious metals explorationproduction, development and developmentexploration company with the objective of becoming a premier silver producer. We are currently focused on the advancementproduction and continued development of our two principal projects:the Cerro Los Gatos Mine and the further exploration and development of the Los Gatos District:

        The Cerro Los Gatos Mine, located within the Los Gatos District, Chihuahua, Mexico, consists of a 2,500 tpd polymetallic mine and processing facility that commenced production on September 1, 2019. For the year ended December 31, 2019, at the Cerro Los Gatos Mine, 357,342 tonnes were mined and 269,853 tonnes were processed at average grades of 229 g/t silver, 0.52 g/t gold, 1.97% lead and 3.03% zinc, with metallurgical recovery of 82.1% silver, 63.5% gold, 83.4% lead and 72.3% zinc. For the six-months ended June 30, 2020, at the Cerro Los Gatos Mine, 288,882 tonnes were mined and 298,331 tonnes were processed at average grades of 195 g/t silver, 0.44 g/t gold, 2.22% lead and 3.41% zinc, with metallurgical recovery of 82.2% silver, 61.8% gold, 85.1% lead and 72.4% zinc. The Los Gatos Technical Report, which has an effective date of July 1, 2020, estimates that the deposit contains 9.6 million diluted tonnes of proven and probable mineral reserves (or 5.0 million diluted tonnes of proven and probable mineral reserves on a 51.5% basis), with 6.4 million diluted tonnes of proven mineral reserves (or 3.3 million diluted tonnes of proven mineral reserves on a 51.5% basis) and 3.3 million diluted tonnes of probable mineral reserves (or 1.7 million diluted tonnes of probable mineral reserves on a 51.5% basis). Average proven and probable mineral reserve grades are 306 g/t silver, 0.35 g/t gold, 2.76% lead and 5.65% zinc.

        The Los Gatos DistrictThe Sunshine Mine, located in Idaho, is one of the highest-grade known primary-silver deposits worldwide, with an estimated 2,880,312 tonnes of mineralized material at an average silver grade of 781.7 grams/Tonne (inclusive of expected mining dilution). In December 2012, an independent preliminary economic assessment was completed on the Sunshine Mine, indicating a robust silver project.

      The Los Gatos Project, located in Chihuahua, Mexico, is comprised of a 149,083 hectare land position, constituting a new mining region. The Los Gatos Project consists of three identified silver discoveries, the Cerro Los Gatos zone, the Esther zone and the Amapola zone, and 10 other priority targets. In December 2012, an independent technical report completed on the Company’s primary zones of focus at the Los Gatos Project estimated that the Cerro Los Gatos deposit contains 5,270,000 tonnes of mineralized material at an average silver grade of 179 grams/Tonne, 2.0% lead and 4.2% zinc; the Esther deposit contains 620,000 tonnes of mineralized material at an average silver grade of 113 grams/Tonne, 0.6% lead and 1.7% zinc; and the Amapola deposit contains 480,000 tonnes of mineralized material at an average silver grade of 101 grams/Tonne, 0.1% lead and 0.2% zinc (estimates are undiluted in-situ).

      We were formed on February 2, 2011 when our predecessor, Precious Metals Opportunities LLC, converted to a Delaware corporation. On March 1, 2011, Los Gatos Ltd. merged with and into us. Prior to the merger, Los Gatos Ltd. eliminated all of its outstanding related-party debt through the issuance of preferred shares, which were subsequently exchanged for shares of our common stock in connection with the merger. In connection with the merger, outstanding ordinary shares of Los Gatos Ltd. and options to purchase ordinary shares of Los Gatos Ltd. were also converted into shares of our common stock and options to purchase shares of our common stock, respectively. The assets and liabilities of each predecessor company are presented at historical cost as this transaction was reported for accounting purposes as a combination of companies (Los Gatos Ltd. and Precious Metals Opportunities LLC) under common control. In accordance with U.S. GAAP, common control exists between the predecessor Sunshine and Los Gatos entities as both entities were primarily owned by certain trusts under the control of one individual. In accordance with U.S. GAAP, all financial reports have been prepared as if the combination of the companies under common control had occurred prior to the earliest period presented.

      Our entire source of funds to date has been proceeds from financing activities. From March 1, 2011 to June 1, 2011, we received proceeds of $163,733 through private placements of our common stock to investors. We have not received any additional funding subsequent to June 1, 2011.

      We have not yet generated any operating revenue. We anticipate that we will continue to incur significant operating costs without realizing any revenues at the Sunshine Mine until at least late 2014 or the Los Gatos

      Project for the foreseeable future. We believe that the anticipated net proceeds from this offering and our existing cash and cash equivalents will provide adequate funds for ongoing operations, further exploration in the United States and Mexico, planned capital expenditures and working capital to fund mine development, a new processing facility for commercial production of silver-bearing concentrate and a new refinery to bring the Sunshine Mine into sustained commercial production. However, we may elect to seek additional funding prior to bringing the Sunshine Mine into sustained commercial production. We expect that we will require additional funds at a later date to develop a mine at the Los Gatos Project, which depending upon the circumstances may be in the form of equity, debt, joint venture funding or some combination thereof. There can be no assurance that additional funds will be available to us on acceptable terms or at all.

      Principal Projects

      Sunshine Mine

      The Sunshine Mine is located within the Coeur d’Alene Mining District in Idaho. In May 2010, we acquired from Sterling the majority of the operating facilities and equipment at the Sunshine Mine, including a lease on the Sunshine Mine that included a purchase option for title to the Sunshine Mine. In July 2010, we closed the purchase option in the lease to obtain title to the Sunshine Mine and acquired the remaining operating facilities and equipment. The total consideration paid in cash was comprised of (i) $23,500 for the net assets acquired and liabilities assumed and (ii) $5,750 for the right, title and interest acquired in connection with the purchase option. Our consolidated land position at the Sunshine Mine property consists of approximately 3,901 hectares.

      We are undertaking significant exploration and re-development of the Sunshine Mine property. Since acquiring the Sunshine Mine, we have successfully completed or are currently working on the following significant exploration and re-development activities at the Sunshine Mine property:

      acquired additional surface rights;

      repaired surface facilities and equipment, including the Jewell shaft hoists, compressed air, water and pumping systems;

      ongoing repairs to the Jewell shaft;

      commissioned the Silver Summit hoist and completed work to enable rehabilitation of the Silver Summit shaft;

      re-established utility services to the Sunshine Mine ramp, enabling commencement of improvements required for ventilation and re-access to mining blocks;

      completed a drill hole database review for areas of immediate exploration and began compiling the entire historical geologic database to create a three dimensional model of the resources;

      designed a new development plan to re-establish access in the upper and lower mine levels for exploration and development;

      completed an independent technical report in accordance with NI 43-101 and the requirements of Industry Guide 7;

      completed an NI 43-101 compliant preliminary economic assessment to determine the costs to re-commission and operate the Sunshine Mine as a sustainable and efficient silver producer;

      defined additional mineralized material through surface and underground exploration;

      advanced the excavation of the Sterling Tunnel decline to access upper level mineralized blocks for future mining; and

      completed repairs and improvements to the Silver Summit headframe and Consil adit.

      Our objectives at the Sunshine Mine property through 2013 and 2014 are to:

      continue to define additional mineralized material through expanded surface and underground exploration;

      complete the upgrading of the Jewell shaft;

      upgrade the Silver Summit shaft to provide a secondary access to certain underground levels;

      complete a feasibility study if we deem it necessary or appropriate to do so;

      develop sufficient stope access to return the mine to production;

      commence mining in the upper portions of the mine;

      complete the construction of a new modern ore processing facility that will produce silver-bearing concentrates; and

      upgrade other existing infrastructure and re-establish access to developed portions of the resource.

      The Sunshine Mine property will require significant time and capital before this property returns to full-capacity production.

      In February 2012, air monitoring equipment detected an underground fire at the 3100 level of the Sunshine Mine. All mine personnel were safely evacuated, and the federal Mine Safety and Health Administration was notified. The fire was extinguished in March 2012, access to the upper levels of the mine was reestablished in April 2012 and access to the lower levels of the mine was reestablished in June 2012. Subsequent to regaining access to the lower levels of the mine, we determined that the fire did not enter the main shafts or cause any significant damage to the infrastructure of the Sunshine Mine. As a result, we believe the fire will not significantly impact our refurbishment activities or future mine operations. Through December 31, 2012, we have incurred $1,550 of direct costs related to the remediation of the Sunshine Mine fire. We do not expect to incur any significant additional cost related to the fire remediation.

      Los Gatos Project

      The Los Gatos Project is located approximately 120 kilometers south of the state capital of Chihuahua City in Northern Mexico and to date,is comprised of a 103,087-hectare land position, constituting a new mining district. The Los Gatos District consists of 14 mineralized zones, which include three identified silver discoveries, silver-lead-zinc deposits that contain mineral resources—the Cerro Los Gatos Mine, the Esther deposit and the Amapola zones,deposit—as well as 11 additional high-priority targets defined by high-grade drill intersections and 10 other priority targets over 100150 kilometers of outcropping quartz and calcite veins. The area is characterized by a predominant silver-lead-zinc epithermal mineralization.

      Prior to our initial acquisition of exploration concession rights in 2006, very limited historical prospecting and exploration activities had been conducted at On September 1, 2019, the Los Gatos Project. We were able to acquire concessions covering approximately 149,083 hectares, and through our exploration, we have discovered a virgin silver region containing high-grade epithermal vein style mineralization throughout our Los Gatos concession package.

      In 2008, we negotiated surface access rights with local ranch owners and obtained environmental permits for drilling. Environmental baseline data collection (climate, water, vegetation, air and social) began in May 2010 in anticipation of future development activities at the Los Gatos Project. Geological work continued with detailed surface mapping, sampling and prospecting of new zones. In 2011 and 2012, we acquired additional surface access rights to continue and expand our drilling activities at the Los Gatos Project. Data on flora, fauna, water, air, climate, security and social impacts are generally collected on a regular basis and we intend to integrate this data into future social, environmental and technical studies for the Los Gatos Project.

      To date, our primary areas of focus have been defining and extending mineralization along the Cerro Los Gatos, Esther and Amapola zones. The Cerro Los Gatos zone extends more than 2,500 meters along strike. The Esther zone extends more than 800 meters along strike. The Amapola zone extends more than 2,000 meters

      along strike and remains open along strike in both directions. As of August 2012, we have completed 345 drill holes in the Los Gatos Project totaling 160,445 meters.

      In 2012, we completed an independent technical report in accordance with NI 43-101 and the requirements of Industry Guide 7 for the combined Cerro Los Gatos, Esther and Amapola zones.

      Our objectives at the Los Gatos Project through 2013 and 2014 are to:

      expand our exploration drilling program;

      conduct social, environmental and technical work on the property with the objective of completing a pre-feasibility study on the Cerro Los Gatos, Esther and Amapola zones;

      perform additional in-fill drilling to further define mineralizationLGJV commenced production at the Cerro Los Gatos Esther and Amapola zones; and

      acquire additionalMine. A core component of the LGJV's business plan is to explore the highly prospective, mineral and surface rights.

      Theunderexplored Los Gatos Project will require significant timeDistrict with the objective of identifying additional mineral deposits that can be mined and capital beforeprocessed, possibly utilizing the Project is brought into production.

      Operating Expenses

      Exploration Expenses

      We conduct exploration activities under mining concessions in Mexico. Historically, we also conducted exploration activities on patented and unpatented mining claims in the United States, and under mining concessionswhich will be conducted in Mexico.the future by SOP following the Reorganization. We expect our exploration expenses to increase significantly as we continue to expand our exploration activities at the Sunshine Mine property, the Los Gatos ProjectDistrict and our other exploration properties. As access to the underground platforms at the Sunshine Mine is achieved, our exploration drilling costs will further increase. Our exploration expenses primarily consist of drilling costs, lease concession payments, assay costs and other geological and support costs at the Sunshine Mine property, the Los Gatos Project and our other exploration properties.

      Pre-development Expenses

      Our pre-development expenses primarily relate to mining infrastructure improvements preliminary economic assessment and scoping studies and care and maintenance activities.activities at the Sunshine Complex. Our mining infrastructure improvement expenses include shaft repair, decline excavation and other underground development costs. Our care and maintenance expenses include facility and surface repair, utility costs and mine-dewatering costscosts. Pre-development activities at the Sunshine Mine.Complex will be conducted in the future by SOP following the Reorganization.

      General and Administrative Expenses

      Our general and administrative expenses consist of salaries and benefits, stock compensation, professional and consultant fees, insurance and other general administration costs. Our general and administrative expenses are expected to increase significantly as we prepare to operate as a public company. We expect higher costs related to salaries, benefits, stock compensation, legal fees, compliance and corporate governance, accounting and audit expenses, stock exchange listing fees, transfer agent and other stockholder-relatedshareholder-related fees, directorsdirectors' and officers’officers' and other insurance costs, and other administrative costs. Immediately prior to the completion of this offering, we intend to enter into a Management Services Agreement with SOP, pursuant to which we will provide certain executive and managerial advisory services to SOP.

      Income Taxes

      As we have incurred substantial losses from our exploration and pre-development activities, we may receive further benefits in the form of deferred tax assets that can reduce our future income tax liabilities, if it is more likely than not that the benefit will be realized before expiration. WeHistorically, we have not recognized these potential benefits in our financial statements and have fully reserved for such net deferred tax assets, as we believe it is more likely than not that the full benefit of these net deferred tax assets will not be realized before expiration. At December 31, 2012,In connection with the Reorganization, we recorded a full valuation allowanceexpect to use approximately $7,100 thousand of $58,463 against these net deferred tax assets. In addition, dueassets to our net losses since inception, we have not paid income taxes to date and therefore there has been no impact on ouroffset federal income tax expenseliability.

      Comparability of Periods

      As a result of our acquisition of the Sunshine Mine in May 2010, we believe that period-over-period comparisons of our operating results are not meaningful and should not be relied upon as a good indicator of our future performance. Prior to our acquisition of the Sunshine Mine in May 2010, our operating results were derived solely from the activities of Los Gatos Ltd. and Precious Metals Opportunities LLC. We commenced activities at the Sunshine Mine after our purchase of the Sunshine Mine net assets out of bankruptcy from Sterling in May 2010. This acquisition was accounted for as a business combination and the Company applied purchase accounting to the assets acquired and liabilities assumed.

      For the year ended December 31, 2012,2019, we experienced a net loss of $59,582$37,818 thousand compared to a net loss of $41,720$11,664 thousand for the year ended December 31, 2011.2018. The $17,862$26,154 thousand increase in net loss is duewas primarily attributable to increases in pre-development and, to a lesser extent, general and administrative expenses. The primary reasons for the change are as follows:following:

        Exploration expense was consistent year over year. Exploration costs at the Sunshine Mine increased duedecreased to increased surface and underground drilling activities and increases in personnel to support the drilling activities. Exploration costs for our Mexico operations decreased slightly in 2012 due to reductions in drilling activities resulting in lower third-party drilling costs.

      Pre-development expense increased by $17,451 to $24,230$1,248 thousand for the year ended December 31, 20122019, compared to $6,779$1,709 thousand for the year ended December 31, 2011. The increase is2018, due to significant underground mining infrastructure improvements atreduced efforts on concessions outside of the Sunshine Mine that commencedLGJV district resulting in November 2011.

      lower labor costs and Mexico concessions holding costs.

      General and administrative expense increased by $643 to $14,516$4,845 thousand for the year ended December 31, 20122019, compared to $13,873$4,396 thousand for the year ended December 31, 2011. The increase was2018, primarily due to higher stock compensation expense incurred in 2012, and additional personnel costs in 2012 due to our establishment of a Denver corporate office in May 2011,increased arrangement fees, partially offset by a reductionan increase in legal, accounting and consulting costs associated withmanagement fees charged to the 2011 merger of Los Gatos Ltd. that did not recur during 2012.

The change is2018, primarily due to foreign currency fluctuations (Mexican peso)the following events that occurred during 2019: the $11,231 thousand dilution loss from LGJV ownership reduction from 70% to 51.5%, the $12,401 thousand increase in equity loss in affiliates related to the LGJV and the $2,705 thousand increase in LGJV loan arrangement fees payable exclusively by us.

      For the year ended December 31, 2011,2018, we experienced a net loss of $41,720$11,664 thousand compared to a net loss of $24,538$12,811 thousand for the year ended December 31, 2010.2017. The $17,182 increase$1,147 thousand decrease in net loss iswas primarily attributable to the following:

      Pre-development expense increased $4,996 to $6,779 in 2011 compared to $1,783 in 2010 primarily due to the May 2010 acquisition of the Sunshine Mine, an increase in employees to support the additional pre-development activities in 2011, and the commencement of mining infrastructure improvements in late 2011.

      General and administrative expense increased $8,390 to $13,873 in 2011 compared to $5,483 in 2010. The increase was primarily due to our establishment of a corporate office in May 2011, legal, accounting and consulting costs to execute our merger with Los Gatos Ltd., raise additional equity financing and prepare for our initial public offering, offset by our acquisition of the Sunshine Mine in May 2010.

      Amortization expense increased $599 to $1,372 in 2011 compared to $773 in 2010 primarily due to the May 2010 acquisition of the Sunshine Mine.

      Other expense decreased $1,454 to $437 in 2011 compared to $1,891 in 2010 primarily due to a reduction in interest expense in 2011. In January 2011, all of the outstanding related-party debt was converted into preferred shares of Los Gatos Ltd.

      Liquidity and Capital Resources

      As of June 30, 2020, and December 31, 2012,2019, we had cash and cash equivalents of $59,991$1,954 thousand and $9,085 thousand, respectively, and working capital of $61,557 compared to$2,405 thousand and $14,990 thousand, respectively. The decrease in cash and cash equivalents of $119,172 and working capital of $119,651 as of December 31, 2011. This decrease was primarily due to a net lossincreased investment in the LGJV, increased related-party receivables and other operation needs, partially offset by an increase in related-party convertible notes.

              For the six months ended June 30, 2020, we borrowed $10,000 thousand by issuing related-party convertible notes and the notes remain outstanding as of $59,582 for the year ended December 31, 2012.

      June 30, 2020. We did not have any related-party debt as of December 31, 2012 and2019. As of June 30, 2020, we could borrow an additional $5,000 thousand by issuing convertible notes under the Convertible Note Purchase Agreement (as defined herein).

              We did not have any related-party debt as of December 31, 2011. In January 2011, all of the $31,000 of related-party debt was converted into preferred shares of Los Gatos Ltd. Pursuant to our merger with Los Gatos Ltd., all Los Gatos Ltd. ordinary and preferred shares were converted into shares of our common stock.2019. We have no outstanding lines of credit or other bank financing arrangementsarrangements. We guarantee 70.0% of the Dowa Term Loan and do not anticipate additional future funding fromthe Los Gatos Working Capital Facility as of June 30, 2020. We have certain arrangement fee obligations related parties.

      Our entire source of funds to date has beenthe Cerro Los Gatos Mine as detailed in the "LGJV Arrangement Fee" above. In 2019, we received $40,465 thousand in equity proceeds from financing activities. From inception through December 31, 2012,our shareholders. In May 2019, we contributed $18,200 thousand to an LGJV entity to provide funding for a partial repayment of principal and interest related to the MPR Loan. In late May 2019, the MPR Loan was fully extinguished with a cash payment of $18,200 thousand and the conversion of the remaining $50,737 thousand of principal and interest to Dowa equity. The conversion of the remaining principal and interest increased Dowa's ownership in the LGJV entities to 48.5%. As of June 30, 2020, the approximate ownership of the LGJV entities is 51.5% in favor of the Company and 48.5% in favor of Dowa. Due to the LGJV ownership dilution, we recognized a dilution loss on affiliates of $11,231 thousand in May 2019. We have received net proceedsan option to repurchase the approximate 18.5% equity interest in the LGJV from Dowa by June 30, 2021, and only after the Los Gatos Working Capital Facility is repaid, for a total consideration of $235,111 from these financing activities.approximately $51,100 thousand and all costs incurred by Dowa in connection with its ownership of such equity interest, including, but not limited to, legal and accounting fees, capital contributions and taxes.

      We believe that, upon the anticipated net proceeds fromcompletion of this offering, and our existingwe will have sufficient cash and cash equivalentsresources to carry out our business plans for at least the next 12 months. We are focused on our forward-looking liquidity needs. We are evaluating our ongoing fixed cost structure as well as decisions related to project retention, advancement and development.

We expect that we will require additional funds at a later date to develop a minesupport operations at the Cerro Los Gatos Project,Mine which, depending upon the circumstances, may be in the form of equity, various forms of debt, joint venture funding or some combination thereof. There can be no assurance that additional funds will be available to us on acceptable terms, or at all.

      Dowa Debt Agreements

              On January 1, 2015, we entered into a joint venture with Dowa to develop the LGJV. Dowa initially acquired a 30% interest in the LGJV and the right to purchase future zinc-concentrate production at market rates.

              On July 11, 2017, we entered into a loan agreement (the "Dowa Term Loan") with Dowa whereby the LGJV could borrow up to $210,000 thousand to finance the development of the Los Gatos project. The principal amount of the Dowa Term Loan accrues interest daily at a rate of LIBOR plus 2.35%, and the interest was added to the amount borrowed until production commenced at the Los Gatos project. The LGJV is obligated to pay 14 consecutive semi-annual payments totaling the aggregate principal amount and capitalized interest beginning June 30, 2021, with payments made two business days prior to the end of each June and December. The maturity date for the Dowa Term Loan is two business days prior to December 31, 2027. The LGJV can prepay the loan from time to time, subject to a minimum amount. We guarantee 70.0% of the Dowa Term Loan. The Dowa Term Loan contains affirmative and negative covenants reasonably customary for similar facilities, with which the LGJV is in compliance in all material respects as of the date of this prospectus.

              On April 16, 2019, we entered into a memorandum of understanding with the LGJV and Dowa, whereby we made a capital contribution to the LGJV in the amount of $18,200 thousand in consideration for partial repayment of a previously existing loan with Dowa of $65,678 thousand entered into with Dowa as of January 23, 2018 (the "MPR Loan"). Under the terms of the memorandum, Dowa agreed to convert the remaining balance of $42,937 thousand outstanding under the MPR Loan in exchange for approximately 18.5% of the equity interests in the LGJV. This diluted our ownership in the LGJV to approximately 51.5%, with Dowa owning the remaining approximate 48.5%. Furthermore, the LGJV will be required to contribute dividend payments to an escrow account until an aggregate amount equal to $20,000 thousand has been deposited into the account, which is payable to Dowa as a priority dividend, as described in a priority distribution agreement dated May 30, 2019 among us, MPR, OSJ and Dowa. See "Business—The Los Gatos District—Priority Distribution Agreement." Following payment of $20,000 thousand to Dowa, dividends will be paid in accordance with the ownership of the LGJV. Under this memorandum of understanding and the terms of an option agreement dated May 30, 2019 among us, MPR, OSJ and Dowa, Dowa granted us an option to repurchase the approximate 18.5% equity interest in the LGJV from Dowa by June 30, 2021, and only after the Los Gatos Working Capital Facility is repaid, for a total consideration of approximately $51,100 thousand and all costs incurred by Dowa in connection with its ownership of such equity interest, including, but not limited to, legal and accounting fees, capital contributions and taxes. See "Business—The Los Gatos District—Option Agreement." If we do not exercise our option by June 30, 2021, the option will expire and cease to have any further effect, after which Dowa may sell all or a

      portion of the interest to a third party. As part of the memorandum of understanding, we entered into a working capital facility agreement dated May 30, 2019, with the LGJV and Dowa (the "Los Gatos Working Capital Facility"), under which Dowa agreed to provide a maximum of $60,000 thousand for the benefit of the LGJV. The interest under the Los Gatos Working Capital Facility is LIBOR plus 3%. We also guarantee 70% of this facility and are required to pay an arrangement fee on the borrowing, calculated as 15.0% per annum of 70.0% of the average daily principal amount outstanding during the relevant fiscal quarter. The Los Gatos Working Capital Facility contains affirmative and negative covenants reasonably customary for similar facilities, with which the LGJV is in compliance in all material respects as of the date of this prospectus. All principal amounts outstanding under the Los Gatos Working Capital Facility will be due on or before June 28, 2021. The full principal amount of the Los Gatos Working Capital Facility has been drawn down by the LGJV.

      Convertible Notes

              On April 20, 2020, we entered into a Convertible Note Purchase Agreement with Electrum Silver US LLC (as amended, the "Convertible Note Purchase Agreement"). Pursuant to the Convertible Note Purchase Agreement, we may issue and sell to Electrum Silver US LLC from time to time, convertible notes on the same terms under the Convertible Note Purchase Agreement until the earlier of (i) such time as the aggregate principal amount of principal indebtedness evidenced by all convertible notes issued and sold under the Convertible Note Purchase Agreement equals $15,000 thousand and (ii) April 20, 2021. Upon the consummation of a sale of equity securities in a bona fide equity financing, including this offering, that results in gross proceeds to us of at least $10,000 thousand from investors not affiliated with Electrum, the convertible notes, including any accrued but unpaid interest, may, at our option, (i) convert into shares of such equity securities at a price per share equal to the lesser of (A) 80% of the price per share of such equity securities and (B) $7.50 per share of such equity securities, subject to adjustment for any stock split (including as part of the Reorganization), stock dividend, reverse stock split, recapitalization or similar transactions, or (ii) be repaid in full. The outstanding principal amount of the convertible notes and any accrued but unpaid interest is due and payable on April 19, 2023. However, any conversion of the convertible notes into equity securities as described above shall be deemed a repayment of the convertible notes so converted. The convertible notes bear interest at a rate of 5.00% per annum, compounding annually. As of the date of this prospectus, we have issued $             thousand aggregate principal amount of convertible notes and there is $             thousand in accrued but unpaid interest.

              At December 31, 2019 and 2018, the LGJV had current assets of $70,187 thousand and $52,936 thousand, respectively. The increase in total current assets was primarily due to an increase in value added tax and trade receivables, partially offset by decreases in cash and other current assets. At December 31, 2019 and 2018, the LGJV had noncurrent assets of $398,733 thousand and $250,833 thousand, respectively. The increase in noncurrent assets was primarily due to increased mine development assets and property, plant and equipment to develop new mining areas and complete site infrastructure, partially offset by accumulated depletion and depreciation that began in 2019.

              At December 31, 2019 and 2018, the LGJV had current liabilities of $57,995 thousand and $91,663 thousand, respectively. The decrease in current liabilities was primarily due to the extinguishment of the Dowa MPR Loan, partially offset by an increase in accounts payable and accrued liabilities. At December 31, 2019 and 2018, the LGJV had noncurrent liabilities of $302,026 thousand and $156,084 thousand, respectively. The increase in non-current liabilities was primarily due to an increase in borrowings under the Dowa Term Loan and the Working Capital Facility.

              For the year ended December 31, 2019, the LGJV had a $22,103 thousand net loss compared to a $662 thousand net loss for the year ended December 31, 2018. The increase in net loss was primarily due to the start and ramp up of production in 2019, as well as beginning to depreciate the assets placed in service and to expense interest and arrangement fees costs upon achieving production. Interest and arrangement fee costs were capitalized during the construction period. For the year ended December 31, 2018, the LGJV had a $662 thousand net loss compared to a $234 thousand net loss for the year ended December 31, 2017. The increase in net loss was primarily due to foreign exchange losses as the Mexican peso declined in value relative to the U.S. dollar reporting currency.

      Stock-Based Compensation

              We recognize all employee and director stock-based compensation as a cost in our consolidated financial statements. Equity-classified awards are measured at the grant date fair value of the award. We estimate the grant date fair value using the Black-Scholes option-pricing model using estimated amounts for volatility of our stock, the expected life of the awards, the fair value of the underlying shares, the risk-free interest rate and the expected dividend yield. The related expense is included as a component of either exploration, pre-development or general and administrative expenses over the requisite service period of the award.

      (1)Does not contain product and sale royalty payments. See “—Royalties.”
      (2)The lease from Metropolitan Mines Corporation relating to certain mining claims at the Sunshine Mine property requires monthly payments of $1 until ore is produced from the Metropolitan property.

This obligation has not been included in the table above as the amount of future exploration costs is unknown.

              Our stock-based compensation includes DSUs granted to certain employees and directors, and stock options granted to employees, directors and various individuals and entities.

              In 2018, we granted 10,000 stock options at a strike price of $4.50 per share. In 2019, we granted 1,203,000 stock options at a strike price of $6.00 per share. During the six months ended June 30, 2020, we granted 1,596,667 stock options at a strike price of $6.00 per share.

              The total stock-based compensation expense incurred for the years ended December 31, 2019, 2018 and 2017 was $3,219 thousand, $2,392 thousand and $1,981 thousand, respectively. The total stock-based compensation expense incurred for the six months ended June 30, 2020 was $2,118 thousand.

      Significant Factors, Assumptions and Methodologies used in Determining Fair Value of Share Based Payments

              Stock-based compensation expense for DSU awards is based on the estimated fair value of our common stock on the grant date.

              Stock-based compensation expense for options is based on the estimated fair value for each award on the grant date. We calculate the grant date fair value based on an option pricing model using estimated amounts for risk-free interest rate, dividend yield, estimated historical volatility of our common stock, the expected life of the awards and the estimated fair value of the underlying common stock. In addition to the assumptions used to calculate the fair value of the options, we are required to estimate the expected forfeiture rate of the option awards, and only recognize stock-based compensation expense for those option awards expected to vest. We recognize stock-based compensation expense as a component of either exploration, pre-development or general and administrative expense on a straight-line basis over the requisite service period of the award.

              The following assumptions were used to compute the fair value of the options granted:

       
       Grant Date

              The following assumptions were used to compute the fair value of the options, that are required to be revalued each reporting period, as of the dates indicated:

       
       December 31, June 30,
       
       2019 2018 2017 2020

      Expected option life

       6 years 6 years 6 years 6 years

              The risk-free interest rate assumption was based on the U.S. treasury constant maturity yield at the date of the grant over the expected life of the option. No dividends are expected to be paid. We calculated the estimated volatility based on the historical volatility of a group of peer companies' common stock over the expected option life. The peer information was used because we were not publicly traded at the time of the grant, and therefore did not have the market trading history required to calculate a meaningful volatility factor. The computation of expected option life was determined based on a reasonable expectation of the option life prior to the option being exercised or forfeited. Based upon our expectation of forfeiture for these grants, we estimated a forfeiture rate of zero for our executive and director option grants, and a forfeiture rate of 10% for our employee option grants.

              As of June 30, 2020, there was approximately $7,751 thousand of unrecognized stock-based compensation expense related to option awards that we expect to recognize over a weighted average vesting period of 2.1 years.

      Common Stock Valuation

              We estimated the fair value of our common stock in 2017, 2018, 2019 and 2020 based on resource multiples, discounted cash flows, comparable property values, comparable public company equity values, changes in comparable public company equity values, and a discount for a lack of marketability. Based on this market data, the corresponding fair value of per share common stock was used in valuing the options and DSUs granted in 2017, 2018, 2019 and 2020.

      Off Balance Sheet Arrangements

      Other than the advanced royalty payments included in “—"Management's Discussion and Analysis of Financial Condition and Results of Operations—Contractual Obligations”Obligations" above, we have no significant off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to our stockholders.shareholders.

      Critical Accounting Policies

      Listed below are the accounting policies that we believe are critical to our financial statements due to the degree of uncertainty regarding the estimates or assumptions involved and the magnitude of the asset, liability or expense that is being reported.

      Equity Method Investment

              We account for our investment in affiliates using the equity method of accounting whereby, after valuing the initial investment, we recognize our proportional share of results of operations of the affiliate in its consolidated financial statements. Equity method investments are reviewed periodically for other-than-temporary decline in value. Our investment in the LGJV is presented as investment in affiliates in the consolidated balance sheet. The difference between the carrying amount of the investment in affiliates and our equity in the LGJV's net assets is due to value of mineral resources at MPR. We incur certain costs on behalf of the LGJV, primarily related to a project development loan arrangement fee. Our proportional share of such costs are reported as an investment in affiliate and the residual costs, related to Dowa's proportional ownership, are reported in the statement of loss.

      Mineral Properties and Carrying Value of Long-Lived Assets

      Mineral property acquisition costs are recorded at cost and are deferred until the viability of the property is determined. Exploration, mineral property evaluation, option payments, related acquisition costs for mineral properties acquired under option agreements, general overhead, administrative and holding costs to maintain a property on a care and maintenance basis are expensed in the period they are incurred. When proven and probable mineral reserves are determined for a property, subsequent development costs on the property are capitalized. If a project were to be put into production, capitalized development costs would be depleted on the units of production basis determined by the proven and probable mineral reserves for that project.

      Existing proven and probable mineral reserves and value beyond proven and probable mineral reserves, including mineralization other than proven and probable mineral reserves and other material that is not part of the measured, indicated or inferred resource base, are included when determining the fair value of mine site reporting

      commodities that will be obtained after taking into account losses during mining, mineralized materialmineral resources processing and treatment and ultimate sale. Estimates of recoverable minerals from such exploration stageexploration-stage mineral interests are risk-adjusted based on management’smanagement's relative confidence in such materials. In estimating future cash flows, assets are grouped at the lowest levels for which there are identifiable cash flows that are largely independent of future cash flows from other asset groups.

      We review and evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Asset impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the asset. An impairment loss is measured and recorded based on discounted estimated future cash flows. Future cash flows are estimated based on estimated quantities of recoverable minerals, expected silver and other commodity prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mineLOM plans. No impairment tests have been required during the periods presented.

      Various factors could impact our ability to achieve our forecasted production schedules from proven and probable mineral reserves. Additionally, production, capital and reclamation costs could differ from the assumptions used in the cash flow models used to assess impairment. The ability to achieve the estimated quantities of recoverable minerals from exploration stageexploration-stage mineral interests involves further risks in addition to those factors applicable to mineral interests where proven and probable mineral reserves have been identified, due to the lower level of confidence that the identified mineralized materialmineral resources could ultimately be mined economically. Assets classified as exploration potential have the highest level of risk that the carrying value of the asset can be ultimately realized, due to the still lower level of geological confidence and economic modeling.

      Income and Mining Taxes

      We recognize the expected future tax benefit from deferred tax assets when the tax benefit is considered to be more likely than not of being realized. Assessing the recoverability of deferred tax assets requires management to make significant estimates related to expectations of future taxable income. Estimates of future taxable income are based on forecasted cash flows and the application of existing tax laws in the United States and Mexico. Refer above to “—Mineral Properties and Carrying Value of Long-Lived Assets”Assets

              Mineral property acquisition costs are recorded at cost and are deferred until the viability of the property is determined. Exploration, mineral property evaluation, option payments, related acquisition costs for mineral properties acquired under option agreements, general overhead, administrative and holding costs to maintain a property on a care and maintenance basis are expensed in the period they are incurred.

              Existing proven and probable mineral reserves and value beyond proven and probable mineral reserves, including mineralization other than proven and probable mineral reserves and other material that is not part of the factors that could cause future cash flows to differ from estimates. To the extent that future cash flows and taxable income differ significantly from estimates, our ability to realize deferred tax assets recorded at the

      balance sheet date could be impacted. Additionally, future changes in tax laws in the jurisdictions in which we operate could limit our ability to obtain the future tax benefits represented by our deferred tax assets recorded at the reporting date.

      Our properties involve dealing with uncertainties and judgments in the application of complex tax regulations in multiple jurisdictions. The final taxes paidmeasured, indicated or inferred resource base, are dependent upon many factors, including negotiations with taxing authorities in various jurisdictions and resolution of disputes arising from federal, state, and Mexico tax audits. We recognize potential liabilities and record tax liabilities for anticipated tax audit issues, if any, in the United States and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes will be due. We adjust these reserves in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional charge to expense would result. If an estimate of tax liabilities proves to be greater than the ultimate assessment, a tax benefit would result. We recognize interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

      Stock-Based Compensation

      Our stock based compensation includes stock options granted to employees, directors and various individuals and entities on our former Advisory Board. On October 30, 2012 the Company granted 1,494,682 options at a strike price of $13.83 per share and all of the options granted in 2011 were cancelled.

      Common Stock Valuation

      We estimated the fair value of our common stock in March2017, 2018, 2019 and May 2011 based on a market value approach of our common stock. During March 2011, an unrelated party purchased 15% of our common stock for $13.83 per share. Subsequent to this purchase through September 30, 2011, investors purchased approximately 6% of our common stock for $13.83. Accordingly, based on this market data, a fair value of $13.83 per share of common stock was used in valuing the options granted in March and May 2011. We estimated the fair value of our common stock in July 2011, August 2011, October 2012 and February 20132020 based on resource multiples, discounted cash flows, comparable property values, comparable public company equity values, changes in comparable public company equity values, and a discount for a lack of marketability. Based on this market data, the corresponding fair value of per share common stock was used in valuing the options and DSUs granted in 2017, 2018, 2019 and 2020.

      The 2010 ordinary share valuation (which also required valuing the outstanding Los Gatos Ltd. preferred shares) was based onultimate assessment, an enterprise value and option pricing model. As an active market for our Los Gatos Ltd. shares did not exist, our analysis was based on estimates of the enterprise value discussed below attributableadditional charge to the ordinary shares of Los Gatos Ltd. From guidance in the AICPA Technical Practice Aid, we selected an option pricing model that treated Los Gatos Ltd.’s ordinary and preferred shares as call options on the enterprise value, with the exercise price based on the liquidation preference of the preferred shares. Given the liquidation

      preference of the preferred shareholders, in some cases a majority of the enterprise value was attributed to the preferred shares in the option pricing model. We calculatedexpense would result.

Additionally, our option pricing model included discount factors of 35% and 20% for lack of marketability and control by a single shareholder, respectively. Based on the assumptions used and the model described above, a value of $0.20 per share was allocated to the ordinary shares granted to an employee of a related entity on June 30, 2010. To estimate the enterprise value, we used the following information:

      A valuation of the assets (exploration properties) held by Los Gatos Ltd. by reference to comparable sales of exploration property and the likelihood of exploration success at our Los Gatos Ltd. properties. Our valuation compiled information on transactions recently completed by companies listed on various stock exchanges and having precious-metals exploration properties in similar geographic areas and political jurisdictions; specifically Mexico. From the review of numerous transactions, a number of appropriate transactions were selected for analysis to establish a range of values for the subject properties as of June 30, 2010. The likelihood of success was determined based upon the activities performed on the various exploration concessions held by Los Gatos Ltd.

      We obtained information on several underground silver-dominated, vein resources/deposits in Mexico that were either in production or the infrastructure was in construction. We estimated a value per silver equivalent ounce for each resource/deposit, where possible.

      In addition, we considered the following subsequent events in support of our valuation:

      A proposed transaction (with an unrelated party that was never consummated) to acquire a portion of Los Gatos Ltd.

      The discussions and negotiations with Liberty Metals and Mining, an unrelated party, that ultimately purchased 15% of Sunshine Silver Mines Corporation in March 2011.

      JOBS Act

      On April 5, 2012, the JOBS Act was signed into law.        The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for qualifying public companies.

      As defined in the JOBS Act, a public company whose initial public offering of common equity securities occurs after December 8, 2011 and whose annual gross revenues are less than $1.0 billion will, in general, qualifypermits us, as an “emerging"emerging growth company” untilcompany," to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to "opt out" of this provision and, as a result, we will comply with new or revised accounting standards on the earliest of:

      the last day of its fiscal year following the fifth anniversary of the date of its initial public offering of common equity securities;

      the last day of its fiscal year in which it has annual gross revenue of $1.0 billion or more;

      the daterelevant dates on which it has, during the previous three-year period, issued more than $1.0 billion in non-convertible debt; and

      the date on which itadoption of such standards is deemed to be a “large accelerated filer,” which will occur at such time as the company (a) has an aggregate worldwide market value of common equity securities held by non-affiliates of $700 million or more as of the last business day of its most recently completed second

      fiscal quarter, (b) has been required to file annual and quarterly reports under the Securities Exchange Act of 1934 for a period of at least 12 months, and (c) has filed at least one annual report pursuant to the Exchange Act.

      Under this definition, we will be an “emerging growth company” upon completion of this offering and could remain anrequired for public companies that are not emerging growth company until as late as December 31, 20    .

      We are in the process of evaluating the benefits of relying on the reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company”, we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis), and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation. However, we have electedcompanies. The decision to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) ofunder the JOBS Act and our election is irrevocable. That provision would have permitted us to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies.

      Quantitative and Qualitative Disclosures About Market Risk

      Commodity Price Risk

      We intend to engage in the production of silver and concentrates containing silver, lead, zinc and antimonygold at the SunshineCerro Los Gatos Mine and the Los Gatos Project.commenced production on September 1, 2019. Accordingly, we expect the principal source of future revenue at the LGJV to be the sale of concentrates containing silver, and to a lesser extent, lead and zinc. A significant and sustained decrease in the price of these metals from current levels could have a material and negative impact on our business, financial condition and results of operations.

      Foreign Currency Risk

      Although most of our expenditures are in U.S. dollars, certain purchases of labor, operating supplies and capital assets are denominated in other currencies, primarily the Mexican Peso.peso. As a result, currency exchange fluctuations may impact the costs of our operations. To reduce this risk, we maintain limited cash balances in foreign currencies and transact most of our purchases in U.S. dollars.

      Concentration of Risk

      We have placed nearly all of our cash investments with a single, high-quality financial institution. All cash equivalents are invested in high-quality, short-term money market instruments, including government securities, bankers’bankers' acceptances, bank notes, certificates of deposit, commercial paper and repurchase agreements of domestic and foreign issuers. At no time have we had funds invested in asset-backed commercial paper. We have not experienced any losses on our cash investments.

      SILVER INDUSTRY OVERVIEW

      The Silver Market

      Overview

      Silver is one of the eight precious, or noble, metals; the others are gold and the six platinum-group metals. Silver occurs naturally in its solid metallic state and is commonly associated with deposits of gold, copper, lead and zinc.

      As an industrial and monetary asset, silver haszinc as a dual personality that differentiates itsecondary metal. Silver is distinct from other precious metals. On the one hand, silvermetals in that it is both used in industrial applications and as an investment asset.

              Silver has a number of distinctive physical and chemical properties that makesmake it an essential component in numerous industrial applications, including its strength, malleability, conductivity and ductility, its sensitivity to and high reflectance of light and its ability to endure extreme temperature ranges. These properties restrict its substitution in most applications. Silver is one of the world's best conductors of electricity and is used in electronic components of common items such as solar panel photovoltaic cells, computers, televisions and cell phones.

      On the other hand, silver        Silver has also been used as a medium of exchange since earliest recorded history. From the time of the Roman Empire until the 19th century, most nations were on a silver standard with silver coins forming the main circulating currency. While silverit is no longer widely used as circulating currency, the metalsilver is still widely sought by investors for its store of value attributes. In particular, silver is viewed as an attractive hedge against a decrease in the value of the U.S. dollarcurrency and inflation during times of economic uncertainty.

      Silver Demand

      Silver has strong supply and        The three principal drivers of silver demand fundamentals with significant demand rooted in diverse sectors. The demand for silver is driven primarily by three uses:are industrial applications, consumer use and investment. According to GFMS,The Silver Institute's World Silver Survey 2020, demand for industrial applications is mainly driven by electrical and electronics uses, which accounted for 58.3% of industrial demand and 30.0% of total demand in 2011, industrial, consumer2019. Jewelry accounted for 20.3% of total demand and net physical investment represented 46.8%, 37.5% and 15.8%18.8% of silvertotal demand.

              Silver demand respectively.

      Industrial and consumer demand for silver, which isgrew 0.4% in 2019 to a three-year high of 991.8 million ounces, from 988.3 million ounces the form of manufactured end-products has remained relatively stable over the past decade. The loss in demand attributable to photography and silverware has been absorbedprevious year, driven by a 12.3% surge in demand for coinsnet physical investment. This was offset by declines in silverware and medallions.

      With rapid populationother industrials. Silver remains difficult to substitute in many areas, and income growth, surgingoutside of a dip in 2009, demand for consumer electronics and a burgeoning housing market, China is the largest global silver marketplace fueling industrial and consumer demand for silver. According to GFMS, silver fabricationapplications has remained broadly flat since 2007.

        Industrial DemandApplications

      Traditional industrial applications of silver include batteries, bearings, brazing and catalysts. Silver, which is the best conductor of electricity among all metals, is used in virtually all electronics. In addition to traditional industrial uses, increases in emerging applications for silver, such as in the electric powertrain and other applications that are increasingly featured in hybrid internal combustion engine cars and electric vehicles, as well as LCD and RFID technologies, are expected to continue to augment industrial demand. Emerging applications include the advent of flexible electronics in which silver batteries play a prominent role, utilizing silver’ssilver's reflectivity as a component in solar cells to produce “green”"green" electricity and utilizing silver’ssilver's antimicrobial properties in medical applications and in the prevention of algae build-up in water purification systems.

      According to GFMS, between 2009 and 2011,        Global industrial demand, forwhich represented 51.5% of total silver rose by 20.1%, to 486.5demand in 2019, totaled 511.5 million ounces.ounces, flat from 2018. A major source of the6.7% increase in silver demand from the photovoltaic sector was offset by an annual decrease in the electronics and electrical sector. Combined, China, the United States and Japan accounted for 347.1 million ounces, representing 67.9% of total 2019 industrial demand for silver was thedemand.

              The electrical and electronics sector. Silver’ssector has consistently ranked as the largest source of industrial silver demand. Silver's electrical and thermal conductive properties make it ideal for multiple high performancehigh-performance electronics and high voltage circuits, connectors and other electrical components, which are all integral parts of electronics. Such uses include switches, contacts, fuses, superconductors and printed circuit boards, which are contained in computers, mobile phones and other smart technologies. According to GFMS,The Silver Institute's World Silver Survey 2020, silver demand from the electrical and electronics sector reached 244.6297.6 million ounces in 2011,2019. At 84.7 million ounces, Japan accounted for 28.5% of 2019 electrical and electronics demand, with China (23.3%) and the second highest level on record, up 30.8%United States (21.0%) also accounting for significant demand.

              Historically, photographic uses represented a large source of silver demand, accounting for 74% of total silver demand in 1999. However, photographic use has since declined significantly, driven by the

        Consumer DemandUse

      Consumer use of silver is primarily        Silver's luster, resistance to tarnishing and malleability are properties well suited for the fabrication of jewelry silverware and coins, which rely on silver’s lustre, resistance to tarnishing and malleability. According to GFMS, the jewelry sector accounted for 15.4% of total demand for silver in 2011, followed by coins and medals with 11.4% of total demand and silverware with 4.4% of total demand.silverware. For these uses, silver is often alloyed to a small proportion of other metals, such as copper, to harden it. Sterling silver, for example, is 92.5% silver and 7.5% copper and has been the standard in many countries for silver jewelry since the 14th14th century. There has been a sharp uptick

              According to The Silver Institute's World Silver Survey 2020, in Chinese consumer2019, the jewelry sector accounted for 20.3% of total demand for silver, as GFMS data indicates that Chinesewhile silverware fabrication rose by 10%accounted for 6.0% of total demand. In 2019, demand for jewelry (201.3 million ounces) and silverware (59.8 million ounces) declined 0.9% and 8.6% year-on-year, respectively. Jewelry demand is driven primarily from South Asia and East, which accounted for 134.4 million ounces, or 66.8% of global demand in 2011 and Chinese jewelry demand continued to grow.

      Historically, photographic uses represented silver’s second largest source of demand, after industrial applications. However, photographic off-take2019.

Other large global markets include Thailand and China (representing 14.2% and 11.3%, respectively, of 2019 global demand). India is also the world's largest consumer of silverware, accounting for 41.2 million ounces, or 68.9%, of 2019 global silverware demand in the area of consumer film. In 2011, photographic uses accounted for 6.4% of total silver demand, according to GFMS.2019.

      According to GFMS, between 2009 and 2011, consumer demand for silver rose by 3.5%, to 390.1 million ounces. Despite a marginal slowdown in demand for photography, jewelry and silverware, consumer demand for silver in 2011 was supported by an increase in demand for silver coins and medals. The fabrication of coins and medals has increased gradually for much of the past decade, but growth has accelerated since the onset of the financial crisis in 2008. According to GFMS, silver demand for coins and medals in 2011 increased 18.9% from 2010, to 118.2 million ounces.

        Investment Demand

      Silver has been a store of monetary value for over 4,000 years.years, and it continues to play an important part in investor portfolio diversification. Historically, the price of silver has shown at times a high correlation to the price of gold as a result of investment demand, and has been at times viewed as an attractive hedge against a decrease in the value of the U.S. dollarcurrency and inflation, attracting investors during times of uncertainty.

              Identifiable physical investment demand increased by 12.3% to 186.1 million ounces in 2019, the largest one-year increase since 2015. The Silver Institute attributes this rise to improved safe haven demand for precious metals from uncertainties stemming from the US-China trade dispute and a manufacturing slowdown in several industrialized countries.

      Investment demand for silver has increased significantlyrepresented a significant portion of total annual silver supply over the last decade. Over the last ten years, investment in coins and metals amounted to 1.1 billion ounces, which was one-tenth of total silver supply over that period. Silver investment demand flourished in the past 10aftermath of the financial crisis and during the height of economic uncertainty in the Eurozone. Between 2013 and 2015, silver physical investment accounted for more than 22% of annual supply, with a peak of 28% recorded in 2015, according to GFMS, formerly known as Gold Fields Mineral Services ("GFMS"). In addition, silver ETP holding rose 13% to 729 million ounces, the largest year-over-year increase since 2010.

      Silver Supply

              Silver supply is primarily driven by mined silver production, which, according to The Silver Institute's World Silver Survey 2020, accounted for 81.7% of supply in 2019. Recycling largely accounted

      for the remainder of silver supply. Global silver supply increased 0.6% year-over-year in 2019 to 1,023 million ounces compared to 1,016.8 million ounces in 2018.

              Mine silver output in 2019 declined for the fourth consecutive year, falling 1.3% to 836.5 million ounces from 847.8 million ounces in 2018. These recent production declines follow 13 consecutive years with the most significant investment demand coming from investment products such as bullion funds and silver ETFs. In 2011, net investmentof growth. The decrease in silver supply was 163.9 million ounces, representing 15.8%largely driven by lower grades at primary silver mines, lower silver production from copper mines and losses from production disruptions. In Peru, Compañía de Minas Buenaventura's Uchucchacua Mine saw silver production decrease from a 27% decline in grades and experienced a 21-day strike; Hochschild Mining's Arcata Mine was placed into care and maintenance early in the year; and declining silver grades were a factor at large primary copper mines. In Mexico, Fresnillo plc achieved lower grades at several of silver demand, according to GFMS. GFMS data indicates that investors purchased nearly 300 million ounces of silverits mines; First Majestic Silver Corp.'s San Martin Mine and Endeavour Silver's El Cubo Mine were placed on care and maintenance; and blockades resulted in 2010, and strong growth in investment demand continued into 2011, as total ETF holdings reached 576 million ounces. Continued macro-economic concerns regarding the sovereign debt crisis in Europe, political problems worldwide, high unemployment in developed countries and rising inflation in developing countries were all factors that attracted investors to silver in 2011.

The remaining 71.3% of silver mined in 2019 was a by-product of lead/zinc, copper, gold and other operations. By-product silver production, which represents over two-thirds of global silver production, is typically inelastic with respect to the silver price.

              Global recycled silver supply also expanded slightly in 2019 by 1.3% to 169.9 million ounces. Industrial recycling is the largest source of recycled silver and rose for the fifth consecutive year. An increase in recycled supply was recorded across all regions, other than the Commonwealth of

      Markets and Outlook

      Over the last twenty five years, the        The price of silver which proved relatively volatile in that timeframe, increased 542.6%.has experienced significant volatility over the last 25 years. The price of silver averaged approximately $4.71 per ounce$4.71/oz from 2000 through the end of 2003. Beginning in 2004, the price of silver began to appreciate considerably, reaching a high of $48.70 per ounce$48.70/oz in April 2011.

      Rising silver prices have boosted investor interest This significant ascent in the metalprice of silver was driven in part by investors' heightened risk aversion amid concerns over the possible effects of quantitative easing measures introduced in the wake of the global financial crises of 2008 and led2009. Subsequent to April 2011, the silver price trended lower, with the average annual price declining for four consecutive years between 2012 and 2015, reaching a significant increaselow of $13.65/oz in silver’s investor base. During 2010, tradingDecember 2015. Between January 1, 2016 and August 31, 2020, the price of silver traded within a range of $12.01 and $28.33/oz.

              In 2019, the average LBMA silver price increased 3.4% year-over-year to $16.21/oz. In 2019, the price of silver reached a high of $19.31/oz, a low of $14.38/oz and ended the year at $18.05/oz. The largest contributor to silver price movements is believed to be the ongoing trade dispute between the U.S. and China, which has had the impact of strengthening the U.S. dollar and weighing on the price of silver and other precious metals. The U.S. Federal Reserve took a dovish stance through 2019, as it lowered the federal funds rate three times.

              The price of silver rallied strongly to multi-year highs in August 2020. As of August 31, 2020, the LBMA silver price has increased 52% compared to the year-end 2019 price. The recent silver price appreciation is believed to have been driven by accommodative monetary policy, aggressive stimulus measures and accelerating investment demand in the midst of the COVID-19 pandemic, as well as disrupted production and a recovery in industrial consumption. These factors have enhanced silver's appeal to investors seeking a hedge against inflation, a decrease in the value of the U.S. dollar and general economic and geopolitical uncertainty. Trading volumes at futures and options exchanges have increased significantly, and the dollar valueETPs inflows have been strong. As of August 31, 2020, silver flows among market participants nearly doubled from 2009 levels. Investor holdings in silver remained at elevated levels during 2011, and total volumes reachedhas a new highlong-term research analyst average consensus price outlook of 621.3 million ounces by late April. According to GFMS, a steep rally in the price$18.75/oz.

      In the short to mid-term, GFMS believes that the economic backdrop for investment in silver will remain supportive as monetary policy is unlikely to significantly tighten in 2012 with ongoing economic, inflation and sovereign debt concerns. This is expected to encourage investment demand for silver and enhance industrial and consumer demand.

      BUSINESS

      The Company

      Sunshine Silver Mines Corporation is a U.S.-based precious metals explorationproduction, development and developmentexploration company with the objective of becoming one ofa premier silver producer. We were formed on February 2, 2011, when our predecessor Precious Metals Opportunities LLC, which was formed in December 2009, converted to a Delaware corporation. On March 1, 2011, Los Gatos Ltd. merged with and into us to form Sunshine Silver Mines Corporation. In 2014, we changed our name to Sunshine Silver Mining & Refining Corporation. In connection with the most profitable primary silver producers, with premium assets in the world’s safest jurisdictions. The Company isReorganization, we intend to change our name to Gatos Silver, Inc.

      Our Principal Projects

              We are currently focused on the advancementproduction and continued development of its two principal projects:the Cerro Los Gatos Mine and the further exploration and development of the Los Gatos District:

        The Cerro Los Gatos Mine, located within the Los Gatos District, Chihuahua, Mexico, consists of a 2,500 tpd polymetallic mine and processing facility that commenced production on September 1, 2019. For the year ended December 31, 2019, at the Cerro Los Gatos Mine, 357,342 tonnes were mined and 269,853 tonnes were processed at average grades of 229 g/t silver, 0.52 g/t gold, 1.97% lead and 3.03% zinc, with metallurgical recovery of 82.1% silver, 63.5% gold, 83.4% lead and 72.3% zinc. For the six-months ended June 30, 2020, at the Cerro Los Gatos Mine, 288,882 tonnes were mined and 298,331 tonnes were processed at average grades of 195 g/t silver, 0.44 g/t gold, 2.22% lead and 3.41% zinc, with metallurgical recovery of 82.2% silver, 61.8% gold, 85.1% lead and 72.4% zinc. The Los Gatos Technical Report, which has an effective date of July 1, 2020, estimates that the deposit contains 9.6 million diluted tonnes of proven and probable mineral reserves (or 5.0 million diluted tonnes of proven and probable mineral reserves on a 51.5% basis), with 6.4 million diluted tonnes of proven mineral reserves (or 3.3 million diluted tonnes of proven mineral reserves on a 51.5% basis) and 3.3 million diluted tonnes of probable mineral reserves (or 1.7 million diluted tonnes of probable mineral reserves on a 51.5% basis). Average proven and probable mineral reserve grades are 306 g/t silver, 0.35 g/t gold, 2.76% lead and 5.65% zinc.

        The Los Gatos DistrictThe Sunshine Mine, located in Idaho, is one of the highest-grade known primary-silver deposits worldwide, with an estimated 2,880,312 tonnes of mineralized material at an average silver grade of 781.7 grams/Tonne (inclusive of expected mining dilution). In December 2012, an independent preliminary economic assessment was completed on the Sunshine Mine, indicating a robust silver project.

      The Los Gatos Project, located in Chihuahua, Mexico, is comprised of a 149,083 hectare land position, constituting a new mining region. The Los Gatos Project consists of three identified silver discoveries, the Cerro Los Gatos zone, the Esther zone and the Amapola zone, and 10 other priority targets. In December 2012, an independent technical report completed on the Company’s primary zones of focus at the Los Gatos Project estimated that the Cerro Los Gatos deposit contains 5,270,000 tonnes of mineralized material at an average silver grade of 179 grams/Tonne, 2.0% lead and 4.2% zinc; the Esther deposit contains 620,000 tonnes of mineralized material at an average silver grade of 113 grams/Tonne, 0.6% lead and 1.7% zinc; and the Amapola deposit contains 480,000 tonnes of mineralized material at an average silver grade of 101 grams/Tonne, 0.1% lead and 0.2% zinc (estimates are undiluted in-situ).

      In total, as of the date of this prospectus, the Company owns or controls a portfolio of 23 exploration properties in the United States and Mexico covering an area of approximately 576,336 hectares.

      Principal Projects

      The Sunshine Mine, acquired by the Company in the first half of 2010, is located within the mining-friendly Coeur d’Alene Mining District in Idaho. As a past-producing mine, the Sunshine Mine is estimated to have produced over 365 million ounces of silver from 1904 to 2008. In 1990, the last year the Sunshine Mine operated at full capacity, silver production from the Sunshine Mine was approximately 5.4 million ounces. In 2008, Sterling, the prior owner of the Sunshine Mine, ceased production and in early 2009 went into bankruptcy due to, we believe, among other factors, falling silver prices and inadequate capital.

      The Sunshine Mine has significant existing on-site infrastructure, including an operational primary shaft, which is being modernized and upgraded, and a secondary shaft, which is being refurbished. The Company’s consolidated land position at the Sunshine Mine property currently consists of approximately 3,901 hectares. The property has an abundant water supply, is connected to the electricity grid and is accessible by paved roads. The Company has all environmental permits in place to begin surface and sub-surface operations. Construction permits will be applied for as needed as the Company begins construction activities.

      The Los Gatos Project is located approximately 120 kilometers south of the state capital of Chihuahua City in Northern Mexico and to date,is comprised of a 103,087-hectare land position, constituting a new mining district. The Los Gatos District consists of 14 mineralized zones, which include three identified silver discoveries, silver-lead-zinc deposits that contain mineral resources—the Cerro Los Gatos zone,Mine, the Esther zonedeposit and the Amapola zone,deposit—as well as 11 additional high-priority targets defined by high-grade drill intersections and 10 other priority targets with over 100150 kilometers of outcropping quartz and calcite veins. The area is characterized by a predominant silver-lead-zinc epithermal mineralization. On September 1, 2019, the LGJV commenced production at the Cerro Los Gatos Mine. A core component of the LGJV's business plan is to explore the highly prospective, underexplored Los Gatos District with the objective of identifying additional mineral deposits

              Prior to our initial acquisition of exploration concession rights in April 2006, very limited historical prospecting and Competitive Advantagesexploration activities had been conducted in the Los Gatos District. We were able to acquire concessions covering approximately 103,087 hectares and, through our exploration, discovered a virgin silver region containing high-grade epithermal vein-style mineralization throughout the Los Gatos District concession package.

              In 2008, we negotiated surface access rights with local ranch owners and obtained the necessary environmental permits for drilling and road construction. Through 2015, we purchased all the surface lands required for the Cerro Los Gatos Mine development. Environmental baseline data collection began in May 2010 and was completed in 2016 and approved in 2017 to prepare for the development of future environmental studies required for the Cerro Los Gatos Mine. In 2014, we partnered with Dowa to finance and develop the Cerro Los Gatos Mine and pursue exploration in the Los Gatos District. We and Dowa formed a Mexico-incorporated co-owned operating company, MPR, which owns certain surface and mineral rights associated with the Los Gatos District. In connection with the formation of the LGJV, we entered into the Unanimous Omnibus Partner Agreement, which governs our and Dowa's respective rights over the LGJV. We own approximately 51.5% of the LGJV, with Dowa owning the remainder. Despite owning the majority interest in the LGJV, we do not exercise control over the LGJV due to certain provisions contained in the Unanimous Omnibus Partner Agreement that currently require unanimous partner approval of all major operating decisions (such as certain approvals, the creation of security interests on property, any initial public offering of the joint venture, and litigation settlements). We intend to exercise our right to repurchase an 18.5% interest in the LGJV from Dowa, increasing our ownership to approximately 70.0%. Following this increase in our ownership interest in the LGJV, we will continue to not exercise control over the LGJV due to the provisions contained in the Unanimous Omnibus Partner Agreement that currently require unanimous partner approval of all major operating decisions. See "—The Los Gatos District—Unanimous Omnibus Partner Agreement."

              We believe that we have strong support from the local community, with over 130 employees from the local community working across multiple areas involving the continued underground development, construction of the surface facilities and operation of the Cerro Los Gatos Mine. Over 99% of the approximate 540 employees at the Cerro Los Gatos Mine hail from Mexico, highlighting our commitment to the local workforce.

              Our primary areas of focus have been constructing and commissioning the Cerro Los Gatos Mine and defining and expanding the mineral resources associated with the Cerro Los Gatos Mine, the Esther deposit and the Amapola deposit. As of July 1, 2020, 739 exploration drill holes have been completed in the Los Gatos District, totaling 259,060 meters. The Los Gatos Technical Report

The mineral resource estimates for the Esther and Amapola deposits have an effective date of December 21, 2012 and have not been updated since that time. The mineral resource estimates contained in the Los Gatos Technical Report are presented on an undiluted basis without adjustment for metallurgical recovery.

              Since the acquisition of the Los Gatos District concession package, we, Dowa and the LGJV have invested approximately $500 million in the development of the Cerro Los Gatos Mine. The Cerro Los Gatos Mine is currently in production. The first lead concentrate was shipped on September 3, 2019, and the first zinc concentrate was shipped on September 4, 2019. We anticipate increasing production to the designed 2,500 tpd rate by the end of the first quarter of 2021.

      Additional Resource Growth Potential from Exploration of the Los Gatos District

              In addition to the significant existing resources at the Cerro Los Gatos Mine, the Los Gatos District also contains the Esther and Amapola deposits and 11 other mineralized zones. With control of the concessions, the ability to develop the entire 103,087-hectare land position and more than 85% of the land position yet to be explored, we expect that we will stand to benefit from mineralization beyond those already identified in the 14 mineralized zones, which include the Cerro Los Gatos Mine, the Esther deposit and the Amapola deposit.

      Assets Located in Geopolitically Safe and Established Mining Regions

      Sunshine Silver’s principal assets are located in two of the world’s premier silver regions.        The Sunshine Mine propertyLos Gatos District is located in one of the Coeur d’Alene Mining District in Idaho, which district is estimated to have produced over one billion ounces ofworld's premier silver over approximately the last century, and the Los Gatos Project is located inmining regions: the Mexican Silver Belt, which was the world’sworld's largest silver producing region in 2011. In2019. Based on a survey published in 2019 by the Fraser Institute, an independent research organization, Mexico is highly ranked among silver mining jurisdictions worldwide in terms of the attractiveness of investment. Mexico also has a long history of successful mineral development and operations, which we believe makes it a desirable jurisdiction in which to conduct mining operations due to stable political, tax and regulatory policies.

              Mexico is the largest producer of silver in the world, in addition to being locateda top-10 producer of gold, lead and zinc, among other major commodities. According to the 2019 Fraser Institute survey, Mexico ranks ahead of many countries in premier silver regions, both assets possess characteristics that differentiate them from other silver projects:

      Sunshine Mine Historical Production and Recent Accomplishments Enhance Operating SuccessSite Exploration Potential Provides Opportunity for Significant Resource Conversion Beyond Existing Mine Plan

      Sunshine Silver believes        We believe that the significant historical production at the Sunshine Mine, combined with the recent and planned mine improvements, lowers project risk and enhances the likelihood of operating success of the project. Significant time and capital investment will be required before the Sunshine Mine returns to production and the Company anticipates that it will continue to incur operating costs without realizing any revenues at the Sunshine Mine until at least 2015, including costs related to intensive underground exploration, rehabilitation and refurbishment of mine and processing infrastructure and further dewatering of underground workings. The underground workings of the Sunshine Mine consist of multiple levels developed off the main production shaft, extending from the surface to a depth of over 1,825 meters, or more than 1,000 meters below sea level.

      Since acquiring the Sunshine Mine, the Company has acquired additional surface rights and improved the existing infrastructure, repaired surface facilities and equipment and completed a number of environmental, health and safety upgrades and identified and accessed a newly discovered portion of the resource that could be mined in the near future. The Company has added experienced and highly-trained professionals to lead such improvements. The Company has accomplished the following for the Sunshine Mine:

      Initiated and expanded exploration drilling

      Discovered an extension of the Sunshine Vein across the Chance Fault, an extension of the Yankee Boy Split Vein and the new “10” vein

      Retained project engineering and development managers

      Engaged geologic resource, metallurgical, environmental, hydrologic and mine planning consultants

      Initiated metallurgical design work for a new process plant

      Initiated a third party concentrate marketing study for silver-bearing concentrates

      Managed the completion of a 3D block model for the first time in the mine’s history

      Started modernizing the Silver Summit shaft and mined two declines for exploration platforms and access within the mine

      Completed an independent technical report in accordance with NI 43-101 and the requirements of Industry Guide 7

      Completed a preliminary economic assessment, which indicated mineralized material production could begin in the second quarter of 2014

      Significant Exploration Potential for Additional Silver Resources

      Sunshine Silver believes that itsour properties have significant exploration upside with numerous opportunities to define additional mineral resources through continued exploration of its properties:exploration.

              The Los Gatos District is located in the Mexican Silver Belt, near several other silver assets owned by large public companies. The Mexican Silver Belt has experienced significant exploration success, and the Los Gatos District represents an underexplored property where there has been little historical workings or previous exploration. The Los Gatos District contains numerous significant high-grade targets throughout. Previous work done has resulted in a 190% increase in measured and indicated silver equivalent resources from March 2014 to September 2019, with additional exploration planned using proceeds from this offering.

              The property has numerous well-defined exploration targets, many of which are extensions of past-producing silver veins. In addition, Sunshine Silver has acquired additionalLGJV owns the surface rights to further consolidate its ownership of this mineralized trend. Despite being a prolific silver producing region, Sunshine Silver believes that the Coeur d’Alene Mining District is still highly under explored. Through application of modern exploration technologies and processes, Sunshine Silver has discovered an extension of the Sunshine Vein across the Chance fault and several other high-grade veins and vein extensions.

      Los Gatos Project: Sunshine Silver expects to expand5,479 hectares covering the Cerro Los Gatos Mine and the Esther and Amapola deposits and the Gavilana (Paula) and San Luis zones, and has been granted mineral concessions for all 103,087 hectares, with 17 contiguous concessions in the Los Gatos District. We have identified 14 mineralized zones within the concessions. Of the 14 mineralized zones, the LGJV has established mineral resource estimates only at the Cerro Los Gatos Mine, the Esther deposit and the Amapola deposit and has conducted drilling on only 15 kilometers out of a strike length of over 150 kilometers of quartz veining along the Los Gatos District.

              The current resources are significant, but we believe that additional resource potential remains in the immediate area. Drill testing of other high-priority targets within the Los Gatos District has been relatively limited given our focus on delineation of reserves at, and construction of, the Cerro Los Gatos Mine. As a result, the highly prospective Los Gatos District remains underexplored. Drilling at the Esther deposit to date has demonstrated good grade continuity along the system and characteristics similar to that identified during preliminary work at the Cerro Los Gatos Mine. Following potentially positive results from infill drilling at the Esther and Amapola deposits, we expect to update the resources and perform a scoping study to determine if these two deposit areas could generate economic production, representing further upside potential for the broader Los Gatos District.

              We expect to perform additional definition drilling to expand the Southeast and Northwest zones of the Cerro Los Gatos Mine and to perform additional drilling to expand the Esther and Amapola deposits, which remain open to extensions at depth. Sunshine Silver also hasIn addition to the Cerro Los Gatos Mine, the Esther deposit and the Amapola deposit, we have identified 1011 other priority targets. Sunshine Silver hasonly conducted drilling on 15 kilometers out of over 100 kilometers of strike length of quartz veining alongmineralized zones defined by high-grade drill intersections in the Los Gatos Project property’s 149,083 hectares.District.

              

      Other opportunities: Sunshine Silver owns 21 other exploration propertiesIn addition to the Los Gatos District, we have 100% control of the Santa Valeria property, located in Chihuahua, Mexico, which is comprised of 1,543 hectares and Idaho, which could provide additionalfurther opportunities for resource growth.

      Politically Stable and Mining-Friendly Jurisdictions

      Both Idaho and Mexico are jurisdictions with a long history of successful mineral development and operations. Both are considered desirable jurisdictions in which to conduct mining operations due to stable political, tax and regulatory policies. Based on a survey published in February 2012 by the Fraser Institute, an independent research organization, Idaho and Mexico rank among the top silver mining jurisdictions worldwide in terms of the attractiveness of government policies, access to infrastructure and qualified labor availability. We believe they are two of the top jurisdictions for mining investment. A number of jurisdictions other than Idaho and Mexico with silver production recently have had issues with local government, including substantial increases in mining taxes, government revocation of mining licenses and restrictions on foreign ownership. These have occurred in jurisdictions such as Peru, Chile, Argentina, Bolivia, Poland, Russia, China and Australia. According to Ernst and Young inBusinessRisksFacing Miningand Metals,resource nationalism is the number one business risk facing mining and metals investment for 2012-2013.

      Attractive Market Dynamics

      Investment demand for silver exposure remains strong, driven in part by continuedvolatility in the U.S. dollar, weakness, ongoing economic uncertainty in Europe and political unrest in the Middle East and elsewhere. Historically, silver has been viewed as an effective hedge against a decrease in the value of the U.S. dollarcurrency and inflation, attracting investors during times of uncertainty. In addition, industrial demand for silver continues to increase, driven by new emerging applications for silver such as solar energy, medical applications and water purification, which the Company believes willwe believe enhance the strong supply and demand fundamentals of silver.

      Despite this strong investment and industrial demand, the universe of primary silver companies is small, which limitshas created a scarcity of investor options for silver exposure. Sunshine Silver represents anWe believe we represent a highly attractive opportunity for investors to gain exposure to a primary silver company with two attractiveworld-class assets.

      The Sunshine Mine Property

      The technical information appearing below concerning the Sunshine Mine property, including estimates of mineralized material, was derived from the reports of Tetra Tech MM, Inc. and MTB Project Management Professionals, Inc., independent mining consultants.

      Location of the Sunshine Mine Property

      The Sunshine Mine property is located within the Coeur d’Alene Mining District in Northern Idaho. Most of the district’s production has come from within a 24.1 kilometer-long band from the Bunker Hill mine to the Galena mine. The Sunshine Mine is approximately in the center of the Bunker Hill and Galena Mine belt. The Sunshine Mine property includes both owned and leased properties containing 200 patented mining claims and 386 unpatented mining claims, for a mineral rights position of approximately 3,901 hectares.

      The Sunshine Mine property is approximately 60 kilometers east of Coeur d’Alene along U.S. Interstate 90. The Jewell Shaft, the mine’s main shaft, is located in the Big Creek Valley at Latitude 47°, 30’, 6” North, Longitude 116°, 4’, 10” West, near the base of a steep hill that lies to the east. The Mine’s infrastructure is located in proximity to the Jewell shaft. Access to the Sunshine Mine property from Coeur d’Alene is by I-90 east to the Big Creek turnoff and then south on about 4.0 kilometers of secondary paved road to the Sunshine Mine site. The nearest town is Kellogg, Idaho, which is about 7.2 kilometers from the Mine.

      Sunshine and CAMP Project

      The Company owns 185 patented and 130 unpatented mining claims covering 1,909 hectares at the Sunshine Mine property, including the CAMP Project claims below 274 meters below sea level. This property includes the Sunshine Mine and mill, the Jewell shaft, surface facilities, a tailings impoundment area and extensive underground workings, including shafts, levels, raises and ramp systems, extending to a depth of over 1,825 meters. The property also includes the ConSil mine and mill and related buildings and equipment. Exceptelsewhere in this paragraph and where the context otherwise requires, when describing the Sunshine Mine property in this prospectus we include the leases set forth below.

      Metropolitan

      The Metropolitan property consists of 2 patented and 70 unpatented mining claims covering 413 hectares. These claims lay immediately to the south of the primary workings of the Sunshine Mine and immediately to the west of the ConSil mine. At depth the claims intersect several veins that were historically mined from the Sunshine Mine.

      Other Sunshine Properties

      In addition to the Sunshine, CAMP Project and Metropolitan properties, the Company leases other claims representing 13 patented claims covering 86 hectares and 186 unpatented claims covering 1,493 hectares.

      Royalties

      Many parts of the Sunshine Mine property are subject to royalties that are payable to parties from whom mineral rights are leased or to others who have a right to royalties on certain areas of the property. Certain of these agreements have royalty payments payable when the Company begins producing and selling metal-bearing concentrate in commercial quantities. These royalties are based on proceeds paid by smelters less certain costs, including costs incurred to transport the concentrates to the smelters, called a net smelter return, or NSR, for ore produced in the property area subject to the royalties.

      All royalty payment amounts below are in thousands of dollars.

      Sunshine Mine

      The Company is required to pay between a 0% (at a silver price below $6 per ounce) and 7% (at a silver price of $10 per ounce or higher) NSR royalty under a settlement agreement with the U.S. government and the Coeur d’Alene Indian tribe. All funds from the royalty must be used to pay for the remediation, restoration and other actions to address certain environmental damage to the Coeur d’Alene River and other natural resources located in the Idaho Silver Valley. The area subject to the royalty covers substantially all of the Sunshine Mine property, owned or leased by the Company, and extends outward within a one mile boundary of the property as set forth in the settlement agreement, which includes the leases set forth above under “—Ownership and Properties.” The Company is also required to pay between a 2% (at a silver price below $5 per ounce) and 4% (at a silver price of $7 per ounce or higher) NSR royalty to Hecla Mining Company. The area subject to this royalty surrounds the Silver Summit/ConSil Mine.

      Metropolitan Mines Corporation Mining Claims

      The Company’s lease with Metropolitan Mines Corporation requires the Company to pay advanced royalties of $12.0 annually until such time as ore is produced from the Metropolitan property. Upon ore production, Metropolitan Mines Corporation is to be paid either 16% or 50% of the net proceeds from the sale of materials produced from the ore processed from these claims, depending upon the location of production.

      Chester Mining Company Mining Claims

      The Company’s lease with Chester Mining Company, or CMC, requires the Company to pay an advance royalty of $7.2 annually until such time as an NSR royalty of 4% or royalty of 20% of net profits on ore processed is payable. The net profit royalty is in lieu of and not in addition to the advance royalty and the NSR royalty. The lease also provides CMC with the option to acquire a 20% working interest in all ores, concentrates, metals or other mineral substances produced from the property. CMC may exercise this option by releasing the Company from its obligation to pay the 20% net profits royalty and by tendering an amount of cash equal to 20% of the then-current working capital fund. The initial lease term ends in 2029 and is renewable for an additional 25 years.

      Mineral Mountain Mining Claims

      The Company’s lease with Mineral Mountain Mining and Milling Company, or Mineral Mountain, requires the Company to pay a royalty of $3.6 annually or a royalty of 3% of net profits, if net profits from the ore processed from these claims exceeds such amount. The lease also provides Mineral Mountain with the option to acquire a 3% working interest in all ores, concentrates, metals or other mineral substances produced from the property. Mineral Mountain may exercise this option by releasing the Company from its obligation to pay the 3% net profits royalty and by tendering an amount of cash equal to 3% of the then-current working capital fund. The initial lease term ends in 2029 and is renewable for an additional 25 years.

      Infrastructure, Climate and Topography

      The Sunshine Mine property has a mild, northern-U.S. climate with snow, rain and fog in the winter. The Sunshine Mine property is tied into the regional power grid, water is abundant from Big Creek, and there are sufficient sources of manpower. Adequate waste disposal areas are present at both the Jewell and the Silver Summit shaft areas. A tailings pond is located on the property. The Company expects that the capacity of the tailings pond as currently configured will be sufficient for approximately ten years after commercial production resumes and that additional capacity may be added thereafter by increasing the height of the pond dam. Mineralized material processing facilities are located on site and will be refurbished or replaced. The topography is typical of northern Idaho’s countryside, hilly to mountainous and forested. The Sunshine Mine property is at an approximate elevation of 790 meters above sea level. The Jewell Shaft is located above the base of a very steep mountain, while the hoist room and other infrastructure facilities are located on a relatively level area of property at the mountain base. The Company is still evaluating potential smelting locations, related transportation and smelting contract terms for the Company’s future production.

      Geological Setting

      The Coeur d’Alene Mining District is hosted by the rocks of the Pre-Cambrian Belt super group. These sedimentary rocks were deposited approximately 1.6 billion years ago. At various times these rocks were faulted, leached, altered and re-mineralized. The Belt super group has been divided into the Pre-Ravalli group, Ravalli group, Piegan group and Missoula group. Within the District, rocks of the Pre-Ravalli, Ravalli, Missoula and Piegan groups can be found. The formations comprising the Ravalli group are, listed from oldest to youngest, the Burke, Revett, and Saint Regis Formations. The District has a history of intense faulting and folding of these rock formations. Two major east-west fault zones, the Osburn and Placer Creek faults, cut through the District.

      Mineralized material deposits in the District are localized in the 182.9 meter thick St. Regis Formation and the underlying upper members of the 914.4 meter thick Revett Formation. Four major west-northwest trending faults cut the Sunshine Mine property area, and some have been mapped for several kilometers. The faults dip steeply to the south. The main vein systems at the Sunshine Mine property include the Sunshine, Chester, Copper, Yankee Girl and West Chance veins. Mineralized silver veins are present within a zone approximately 3,810 meters long by 1,524 meters wide and over a vertical distance of 1,890 meters from the surface at 1,036.3 meters above sea level to 853.4 meters below. The mineralization is open at depth below the 1,707 meter Mine level.

      The Crescent mine is immediately adjacent to the west and the Coeur d’Alene, Coeur, Galena and Caladay mines are adjacent to the east of the Sunshine Mine. Many of the productive vein structures and faults in those adjacent mines pass directly across the Company’s mineral rights position.

      History of the Sunshine Mine Property

      The Sunshine Mine, one of the highest-grade known remaining primary silver discoveries worldwide, is estimated to have produced over 365 million ounces of silver. In 1884, the Blake brothers staked the Yankee Lode mining claim, and various contiguous holdings were consolidated to become the Sunshine

      Mining Company in 1920. In 1921, operations continued and grew at the Sunshine Mine until it was at full production by the end of 1988. In 1992, Sunshine Mining Company merged into Sunshine Precious Metals, Inc., or SPMI. From 1991-2001, there was limited production at the Sunshine Mine primarily as a result of several factors, including a drop in the price of silver and the lack of regular and consistent exploration and development activities. The Mine eventually ceased production in the first quarter of 2001 and Sunshine Mining and Refining Company, or SMRC, the parent of SPMI, declared Chapter 11 bankruptcy. Sterling acquired control of the Sunshine Mine in 2003 through a lease with SPMI, which included an option to purchase the Mine. Beginning in August 2003, and followed by the initial drilling in the fall of 2004, Sterling began an exploration program, and the process of rehabilitation of the underground areas of the Mine began in 2004. The Sunshine Mine returned to production under Sterling for a short period in late 2007. In 2008, Sterling ceased production and in early 2009 went into bankruptcy, due to, we believe, among other factors, falling silver prices ($10.79 per ounce as of December 31, 2008) and inadequate capital. At that time, SNS Silver Corporation took over care and maintenance of the Mine under contract with SPMI. In May 2010, the Company acquired, through Sterling’s bankruptcy proceedings, the majority of the operating facilities and equipment at the Sunshine Mine, including the lease on the Sunshine Mine from SPMI that included a purchase option for title to the Mine. In July 2010, the Company closed the purchase option in the lease to obtain title to the Sunshine Mine and acquired the remaining operating facilities and equipment.

      Exploration

      The Sunshine Mine is without known reserves and the proposed program is exploratory in nature. There are 3,536 historic underground drill holes on the Sunshine Mine property. The longest underground hole is approximately 914 meters. Long underground exploration holes are required to locate structures and veins because most development, except in the West Chance deposit, has been on the vein structure themselves and thus drilling platforms for shorter holes at appropriate angles to the targets have not been available. Historic exploration was primarily constrained by legal property boundaries. Potential targets were also never explored due to limited availability of drills, lack of supporting infrastructure, lack of physical access to provide suitably located drill stations and prohibitive depths from the surface. With the consolidation of the land position, long-known but previously unexplored target areas can now be explored, although some target areas will require new drifting and new drill stations cut.

      The Company is undertaking significant exploration and re-development of the Sunshine Mine property that will require significant time and capital before the property returns to production. The objectives of the current exploration program at the Sunshine Mine are to discover new high-grade veins and mineralized material shoots in areas that already have nearby development, to explore for new large veins in unexplored or under explored areas and to systematically extend known mineralized areas. Since initiating drilling in April 2011, the Company has complete 41 drill holes totaling 15,190 meters as of June 4, 2012. The primary focus of the drilling from the Sterling Tunnel has to been to follow up on open ground within the Sunshine Vein system, while also exploring the Yankee Girl Vein. During the process a new vein structure was identified west of the Sunshine Vein system, referenced as the West Chance Link Vein, with all 16 drill holes revealing significant mineralization. Accessed from the Sterling Tunnel, the Company believes mining of the West Chance Link Vein could begin in a matter of months. The West Chance Link Vein is a linking structure between the Sunshine Vein and West Chance Vein. Additionally, in-fill drilling open ground above the Sterling Tunnel elevation, about the Sunshine Vein, has also identified a new vein structure referenced as the South Yankee Boy Split.

      Since acquiring the Sunshine Mine, the Company has successfully completed or is currently working on the following significant re-development activities at the Sunshine Mine property:

      acquired additional surface rights (2010);

      repaired surface facilities and equipment, including the Jewell hoists and shaft, and compressed air, water and pumping systems;

      ongoing repairs to the Jewell shaft;

      commissioned the Silver Summit hoist and completed work to enable rehabilitation of the Silver Summit shaft;

      re-established utility services to the Sunshine Mine ramp, enabling commencement of improvements required for ventilation and re-access to mining blocks;

      completed a drill hole database review for areas of immediate exploration and began compiling the entire historical geologic database to create a three dimensional model of the resources;

      designed a new development plan to re-establish access in the upper and lower Sunshine Mine levels for exploration and development;

      completed an independent technical study in accordance with NI 43-101 and the requirements of Industry Guide 7;

      completed an NI 43-101 compliant preliminary economic assessment to determine the costs to re-commission and operate the Sunshine Mine as a sustainable and efficient silver producer;

      defined additional mineralized material through surface and underground exploration;

      advanced the excavation of the Sterling Tunnel decline to access upper level mineralized blocks for future mining; and

      completed repairs and improvements to the Silver Summit headframe and Consil adit.

      The Company’s objectives at the Sunshine Mine property through 2013 and 2014 are to:

      continue to define additional mineralized material through expanded surface and underground exploration;

      complete the upgrading of the Jewell shaft;

      upgrade the Silver Summit shaft to provide a secondary access to certain underground levels;

      complete a feasibility study if we deem it necessary or appropriate to do so;

      develop sufficient stope access to return the mine to production;

      commence mining in the upper portions of the mine;

      complete the construction of a new modern ore processing facility that will produce silver-bearing concentrates; and

      upgrade other existing infrastructure and re-establish access to developed portions of the resource.

      Sunshine Mine Mineralogy

      Over 30 veins have been named and mined at the Sunshine Mine property. The main productive vein systems in the property include the Sunshine, Chester, Polaris, Copper, Yankee Girl, West Chance, West Chance Link and South Yankee Boy Split veins. The Sunshine Vein and Chester Vein are each estimated to have produced over 90 million ounces of silver to date. Major veins strike east-west and typically dip about 65% to the south. Locally, dips range from 45º to 90º. Vein strike lengths are up to 610 meters, with dip lengths two to three times greater than that of the strike length. Major veins are located between the regional and property-wide faults at an angle of about 25º to the bounding faults. Veins vary in width from a few inches to over nine meters, but are generally between 0.3 to 1.5 meters thick. Typically, the Sunshine Mine mineralized material consists principally of tetrahedrite and galena. Tetrahedrite occurs as very fine grains in fracture filings, veinlets or discontinuous blebs in the vein-filled faults. This silver-bearing tetrahedrite is more properly called freibergite and contains 3% to 30% silver substituting for the copper in the crystal structure. Gangue minerals are predominantly siderite with lesser amounts of quartz. Galena is present in the West Chance Vein, the Silver Syndicate Vein and the Chester

      Hook Vein. Other metallic minerals seen in the gangue are pyrite, arsenopyrite, and, rarely, boulangerite, bournonite, pyrargyrite and magnetite.

      Sampling and Analysis

      Underground chip samples are collected for daily grade control and for resource estimation. Daily samples are collected underground from drift faces, stope faces, drift backs, drift ribs and raise ribs. Samples are taken by collecting chips in a horizontal channel, left to right, across the mining face. Sampling protocol for channel samples is to collect separate samples of exposed wall rock on both sides of the apparent mineralized vein, and across the mineralized structure or vein samples are collected perpendicular to the mineralized structure. Multiple samples are taken across a face based upon changes in mineralization intensity or composition. Samples are a maximum of 5.0 feet in length. Each sample face has a referenced control distance to an established survey point. After samples are collected, the geologists carry them to the surface where they are secured, inventoried and transported to the assay lab. Drifts on the veins are generally sampled at four to six foot intervals. The analyses from the face samples taken during development and from samples taken as production mining proceeded are the primary sources of data that the Company uses to estimate mineralized material at the Sunshine Mine.

      Drilling done at the Sunshine Mine for mineralized material estimation is done with diamond core drills. Core samples are collected through the vein or mineralized structure. Additional core on both sides of the mineralized zone are sampled to characterize waste dilution. No samples taken for assay are greater than five feet; large zones are broken into increments of five feet or less. When core is lost through a mineralized zone the total drill thickness of the zone is used for volume estimation. The portion of a diamond drill hole used to calculate the reserve for a given vein must be corrected to account for the true thickness of the vein at that point. The down hole length of the intercept is multiplied by the sine of the vein angle to the core axis.

      It is the drill contractor’s responsibility, subject to the logging geologist’s review, to ensure correct numbering of core boxes and for drill core recovery. The core, coarse rejects and pulps are locked in a secure location and stored. Access will only be available to approved personal. Drill holes will have collar and downhole surveys. All core is digitally photographed with a standard fixed mount camera base, having all core run intervals clearly marked on each box. A standardized paper logging form and standardized rock, mineral and alteration color codes are utilized during core logging procedures. The core is logged in detail, including lithology, structure, alteration, mineralization and bedding forms. Core recovery and rock quality data are included in the log. All structures are measured in relation to the core axis.

      After they are collected, core samples, rock chip, channel and select samples are placed in bags with identification tags and are tied closed at the sample site. The bags are marked externally with the same sample identification as the sample tag. The samples are placed in a designated location within the core logging facility until they are transported to the assay lab. The samples and a submittal sheet chain of custody are either transported to the lab by a Company employee, or are picked up directly by a lab representative. The sample tags in the bags and the submittal sheet indicate a unique number for each sample and the chemical elements that are to be analyzed.

      Historically, core and underground samples were delivered to the sample preparation facility on-site by the geologist who logged the core or took the sample. The samples were crushed and ground and delivered to the laboratory for analyses. Company employees did all of the sample preparation, analyses and posting of results on-site. Sample preparation includes discussion with supervisors about the interval, splitting of core, sampling and delivery to the laboratory. This chain of custody maintained the sample integrity.

      Samples are analyzed by American Analytical Services, a third party contractor, using Atomic absorption (AA) and induced coupled plasma techniques to determine silver, copper, lead, zinc and antimony content. AA silver values assaying over 1,134 grams per ton silver are also fire assayed for silver. The fire assay results are preferentially utilized in all calculations. American Analytical Services performs internal laboratory checks that include duplicate assays for fire and AA assays and additional duplicate assay checks for additional base metals.

      Drilling

      The current drill database contains approximately 3,536 underground drill holes. Historic core logs with appropriate descriptions exist with the exception of a single surface hole log book, which has been identified as “misplaced” during a past change of property ownership. The historical drill operators were competent and core recovery in the mineralized zone was generally 90% or higher.

      The current drilling for exploration, delineation and development conducted at the Sunshine Mine property has been performed with diamond core drills. Down-hole surveys are attempted on all diamond drill holes. The primary survey tool is a REFLEX EZ-AQ multi-shot down-hole survey camera. Core diameters range from 2.7 to 4.8 centimeters. Core recovery is generally very good, exceeding 90 percent. Core recovery can be difficult in certain faulted or shear areas. The diamond drillers will change from wireline tools to conventional tools before encountering proven areas of loss, which significantly improves recovery. Recovery issues do not materially impact the reliability of the results.

      To date three new vein structures have been defined with drilling from the Sterling Tunnel elevation. Two new silver-copper veins have been defined in the immediate hanging wall of the historic Sunshine Vein and are named the West Chance Link Vein and the South Yankee Boy Split Vein. Additionally, a new lead-silver vein, named the ”10 vein,” has been recently discovered 61 meters within the footwall of the Sunshine Vein. All veins carry economic silver-copper or lead-silver values. Drilling is continuing to define the vertical and lateral limits of the new vein structures.

      Sunshine Mine Mineralized Material Estimate

      This mineralized material estimation was completed by Tetra Tech in MicroMine® mining software utilizing data supplied by the Company. Utilizing drill hole and channel assays data, Tetra Tech created best fit vein surfaces and estimated mineralized material along those vein surfaces. Ordinary Kriging was used to estimate 3D points along a string type block model for 38 veins. This mineralized material estimate has been diluted to a fixed mine width of 1.98 meters and is an in situ resource estimate. A base-case cutoff has been applied but no other economic parameters have been considered. All metal recoveries are assumed to be 100%.

      Assay data necessary to facilitate this mineralized material estimate was derived from three sources: drill holes, level drift channel samples and stope channel samples. Drill hole assays were provided by the Company from a collated drill hole database, encompassing historic and modern drilling. Level drift channel sampling was digitized from historic level plan maps. Stope channel samples were digitized from historic stope production sheets. Because channel sampling was conducted across true thickness and drill holes were corrected for true thickness, all three data sources were able to be used simultaneously for resource estimation.

      To be classified as mineralized material, a block was required to be estimated using data points inside a search range from 27 to 46 meters. Block estimates from this pass were classified as mineralized material if certain minimum data points were met, subject to data type availability on a vein by vein basis.

      A secondary Kriging pass was made using a search ellipsoid ranging from 7.6 to 15 meters and requiring a minimum of three samples to estimate. In addition to meeting the search ellipse criteria the block estimate was required to reside within bounding strings. The bounding strings were drawn to limit block estimation along strike from previous mined out areas.

      A density of 0.283 cubic meters per tonne (m3/T) is used to convert volumes to tonnage except for the West Chance Vein where a density of 0.269 m3/T was used.

      The table below summarizes the mineralized material at the Sunshine Mine property as of December 2012 using a cutoff grade of 342.9 grams per Tonne (g/T). The mineralized material in the table below contains the expected mining dilution and mining losses and does not reflect in-situ grades.

      Location of the Los Gatos ProjectDistrict and Access

      The Los Gatos Project, an exploration stage property,District, covers approximately 149,083103,087 hectares in the south-central part of the State of Chihuahua in Northernnorthern Mexico, within the municipality of Satevó. The ProjectLos Gatos District is roughly centered on Latitude 27° 34' 17" N, Longitude 106° 21' 33" W, near the town of San José del Sitio. The Los Gatos District is located approximately 120 kilometers south of the state capital of Chihuahua City and approximately 100 kilometers northwest of the Parral Mining District and immediately northwestmining city of and surrounding the townHidalgo del Parral.


      Table of San José del Sitio, within the municipality of Satevó.Contents

      San José del Sitio is accessible by a gravelnearly 100% paved road from the turnoff of Federal Highway 24 at the 81 kilometer marker between the cities of Chihuahua and Hidalgo de Parral. The access road can be traveled by any motorized vehicle and has regular bus and supply services to the surrounding communities. The Los Gatos ProjectDistrict area is accessible by a large network of dirt and gravel roads that are used by local owners and lessees to access grazing areas for cattle and local ranches. Northern areas of the Los Gatos ProjectDistrict are also accessible from several gravel roads connecting with Mexican Federal Highway 24 between the 60 kilometer to 81 kilometer markers. In more remote areas, the rolling topography permits easy access by foot into areas where roads do not exist.

              There are a limited number of qualified workers in San José del Sitio, but, technical workers (e.g., miners, electricians, mechanics, computer technicians, etc.), heavy equipment and specialized operators can be found in the surrounding area and at Parral, 88 kilometers southeast. Primary and secondary-level technical schools are available in Valle de Zaragoza, and all levels of schooling are available in Parral and/or Chihuahua, each 2.5 hours away by vehicle.

              See "Risk Factors—The title to some of the mineral properties may be uncertain or defective, thus risking our investment in such properties" for a discussion of factors or risks that may affect access or title or the right or ability to perform work on the property.

              See Section 4.1 of the Los Gatos Technical Report for further specific information of the location of the Los Gatos District.

MPR holds the rights        In addition to the concessions of Los Gatos and Paula Adorada through exploration agreements with purchase options. These agreements have been duly recordedlisted in the Méxican Public Registry of Mines. Details of these exploration agreements are provided below.

      All royalty payments below are in thousands of dollars.

      Los Gatos Concession: MPR is required to make semi-annual payments to La Cuesta International (LCI) to obtain ownership of the concession, and is required to make a production royalty payment of 2% net smelter return on production from the Los Gatos concession and 0.5% net smelter return from lands within a one kilometer boundary of the Los Gatos concession. Once total royalty payments reach $10,000, the 2% net smelter return will decease to 0.5%. Once total payments have reached $15,000, the Los Gatos concession ownership will be transferred to the MPR.

      MPR has negotiated an agreement in principal with LCI for a cash-out and elimination of the royalty obligation in exchange for payment to LCI of $6,750 and initial payment of US $50, which will be paid once the agreement is finalized. The balance of payment is due and the settlement complete upon the successful completion of an initial public offering by the Company that includes gross proceeds of not less than $150,000. In the event that the offering is not completed before March 31, 2014, the payment amount will increase 8% per annum.

      Paula Adorada Concession: MPR may purchase the Paula Adorada concession from Grupo Factor for $500, according to a payment schedule. Once the final payment is made in 2013, the concession will be transferred to MPR with no further ongoing payment obligations to Grupo Factor.

      MPR has also filed the following mining concession applications that have not yet been titled by the México Direccion de Minas (the Department of Mines), or DGM:

              These concessions are held by MPR. The concessions have a period of validity that ranges between 2054 and 2062. MPR holds the rights to the concessions of Los Gatos and Paula Adorada subject to the terms of an agreement with the original holder of the concession. These agreements have been duly recorded in the Méxican Public Registry of Mines. Details of these agreements are provided below.

      Infrastructure, Royalty and Agreement on Los Gatos Concession

              The Los Gatos concession (title 231498) is subject to the terms of an exploration, exploitation and unilateral promise of assignment of rights agreement made between La Cuesta International, S.A. de C.V. and MPR, dated May 4, 2006. Pursuant to this agreement, title to the Los Gatos concession was transferred to MPR and in connection with the transfer MPR is required to make semi-annual advanced royalty payments of $20,000 to La Cuesta International, S.A. de C.V. until the commencement of commercial production and thereafter is required to pay a 2% net smelter returns royalty on production from the Los Gatos concession and a 0.5% net smelter returns royalty from lands within a one-kilometer boundary of the Los Gatos concession, subject to a minimum royalty payment in the same amount as the advanced royalty payment. Once total royalty payments reach $10 million, the 2% net smelter returns royalty will decrease to 0.5% and once total payments have reached $15 million, the royalty will no longer be payable. MPR paid a royalty payment of $40 thousand per year during the preproduction period. Upon commencing production, payments under this agreement were deferred until March 31, 2021 with an annual interest rate of 4.5% applied to the outstanding balance. During the deferral period, MPR will pay an advance royalty payment of $100,000 per year until January 2021. As of June 30, 2020, $14,400 thousand remained for future royalty obligations. During the term of the agreement, MPR is required to comply with all mining, environmental and other applicable laws in order to maintain its right and title to the Los Gatos concession.

      Agreement for Paula Adorada

              The Paula Adorada concession was acquired from Chihuahua-based company Grupo Factor through an option to purchase agreement in effect from 2008 to 2013. Once all obligations and payments were completed during the term of the agreement, the registered ownership of the Paula Adorada concession (title 223392) was transferred from Grupo Factor to MPR in 2014, with no remaining obligations or royalties.

      Unanimous Omnibus Partner Agreement

              The Los Gatos District is owned and operated through the Unanimous Omnibus Partner Agreement. Pursuant to this agreement, the LGJV cannot make any "Major Decisions" without first having obtained Dowa's consent or without first having obtained the consent of holders of at least 90% of the interest in the LGJV, depending on the time such Major Decisions are made. Major Decisions, as defined in the agreement, include the significant operating decisions of the LGJV, such as, among other decisions, budgeting, development and exploitation approvals, loan and outside financing approvals, expansion of area of interest, surrendering claims, the creation of security interests on property, any initial public offering of the joint venture, and litigation settlements. Therefore, despite holding a majority equity interest in the LGJV, we do not exercise control over the LGJV.

              We intend to exercise our right to repurchase an 18.5% interest in the LGJV from Dowa, increasing our ownership to approximately 70.0%. Following this increase in our ownership interest in the LGJV, we will continue to not exercise control over the LGJV due to certain provisions contained in the Unanimous Omnibus Partner Agreement that currently require unanimous partner approval of

      all major operating decisions (such as certain approvals, the creation of security interests on property, any initial public offering of the joint venture, and litigation settlements).

      Option Agreement

              On May 30, 2019 and in connection with the memorandum of understanding dated April 16, 2019, we entered into an option agreement with MPR, OSJ and Dowa, pursuant to which Dowa granted us an option to repurchase the approximate 18.5% equity interest in the LGJV by June 30, 2021, and only after the Los Gatos Working Capital Facility is repaid, for a total consideration of approximately $51.1 million and all costs incurred by Dowa in connection with its ownership of such equity interest, including, but not limited to, legal and accounting fees, capital contributions and taxes.

      Priority Distribution Agreement

              On May 30, 2019 and in connection with the memorandum of understanding dated April 16, 2019, we entered into a priority distribution agreement with MPR, OSJ and Dowa, pursuant to which we directed the LGJV to contribute dividend payments to an escrow account until an aggregate amount equal to $20 million has been deposited into the account, which is payable to Dowa as a priority dividend.

      Sales Agreements

              OSJ (the "Seller"), an entity that forms part of the LGJV, entered into a delivery contract, dated April 14, 2019, with Metagri S.A. de C.V. ("Metagri"), whereby Metagri agreed to buy and accept delivery of, and the Seller agreed to sell and deliver to Metagri, all lead concentrate that will be produced from the Cerro Los Gatos Mine until December 31, 2021. The lead concentrate will ultimately be delivered to Metagri's warehouse in Manzanillo, Mexico.

              The Seller also entered into a delivery contract, dated July 15, 2019, with Ocean Partners, whereby Ocean Partners agreed to buy and accept delivery of, and Seller agreed to sell and deliver to Ocean Partners, all zinc concentrate that will be produced from the Cerro Los Gatos Mine until June 30, 2022. The zinc concentrate will ultimately be delivered to Dowa's zinc smelter in Akita, Japan, unless otherwise agreed to by Dowa. The Seller, from time to time, will enter into memoranda of agreement setting forth the terms and conditions for the sales of zinc concentrate.

              From time to time, the Seller may enter into certain spot sale contracts should impurities in lead and zinc concentrate exceed certain specifications. Since the commencement of production, the Seller has entered into spot sale contracts due to high fluorine content for some production.

      Climate and Topography

      The Company’s present field camp is located in San José del Sitio, a community of approximately 200 persons, with electrical and water services, an elementary school and basic health services. Water resources in the region are mostly related to the Conchos River Basin, which includes the San Pedro, San Francisco de Borja and Satevó River Sub-Basins. Locally, there is significant groundwater deposits, with shallow groundwater recorded from most exploration drilling conducted by the Company. San José del Sitio is served by a 13.8-KV line, providing sufficient capacity for domestic needs but not enough for industrial needs. Larger-capacity electrical lines service the nearby city of Valle de Zaragoza, 45 kilometers to the southeast of the project area, where the 113-MW Santiago (Valle de Zaragoza) electrical sub-station is located.

      The Los Gatos ProjectDistrict area is located in the Sierras y Llanuras del Norte Physiographic Province near the boundaries between the Gran Meseta, y Cationes andCañones, the Sierras yand Llanuras Tarahumara Sub Provinces. The general physiography of the Los Gatos areaDistrict is characterized by low to middle rolling volcanic hills with local escarpments and flat valley floors. Altitudes vary with between 1,550 masl at the base of the Santo Toribio Creek and 1,780 masl at the top of the Los Gatos Hill, one of the highest peaks of the Los Gatos ProjectDistrict area.

              Vegetation is characterized by a semi-desert landscape, with typical low brush vegetation in the slopes, including lechuguilla, sotol, yucca, sage, bear grass and other types of indigenous grasses. Larger brush and trees are common along the main watercourses, with the presence of oak, cypress, poplar, huizache and mesquite, among others.

      GRAPHIC

      Geological Setting

      The Los Gatos ProjectDistrict is located in the transition zone between the Sierra Madre Occidental volcanic province of western Mexico and the Mesozoic Chihuahua basin to the east. It is also located in the general union ofcontact zone between the Sierra Madre Occidental, Chihuahua and Parral tectonostratigraphic terranes.

      The area is largely characterized by a thick sequence of Tertiary volcanic rocks that are generally dissected by a strong north-northwest bearing fault system that divides the area into the plateau and barranca sections and are

      subdivided in two major units, the Lower Volcanic Group and Upper Volcanic Group. The area is one of the largest known epithermal, precious-metal metallogenic provinces and is host to several well knownwell-known gold-silver producing mining districts in Mexico, such as Concheño, Batopilas, San Dimas-Tayoltita and Ocampo.

      The dominant rocks of the Los Gatos ProjectDistrict area are thick accumulations of intermediate tuffs and lavas, with lesser felsic rocks, and Upper Cretaceous (Cenomanian) to Lower Paleocene aged sandstones, shales and limestones correlative with the Mezcalera formation, locally metamorphosed to phyllites, quartzites and marbles near areas of igneous activity. Rocks of this oldest sedimentary sequence occur within a small horst block located to the northwest of the Cerro Los Gatos system,District, with prominent high-angle fault boundaries on the north and south, parallel to the regional trend of faulting. Intruding and deposited on the entire section are locally important rhyolite flows, flow domes and dikes, usually strongly silicified, that have all of the varied textures expected with the development of flow domes, including autobreccias,breccias, flow banding and intrusive/extrusive transitions. Each of the rocks in the section contains observable hydrothermal alteration that suggests that mineralization in the area probably occurred late in the history of the development of the volcanic section. It is important to stress, however, that economic grades of mineralization have only thus far been identified in the andesite and dacite sections.

      History of the Los Gatos ProjectDistrict

      The Los Gatos ProjectDistrict has been the subject of very limited historical prospecting and mineral exploration, including the development of shallow workings and preliminary exploration activities by Consejo de Recursos Minerales (now SGM)the Servicio Geológico Mexicano, the Mexican Geologic Survey) at the Esther, Gavilana (Paula) and San Luis zones with references to the occurrence of silver, lead and zinc. As a result, the Los Gatos Project will require significant timeThe construction and capital before the Project may be brought into production. The Company’s surfacedevelopment work has not uncovered any evidence of past modern prospecting activities in the area. The Los Gatos ProjectDistrict was initially recognized by reconnaissance activities by La Cuesta International Inc. in 2005 and later offered to Los Gatos Ltd. (parent(original parent of MPR). An initial letter of agreement for exploration work on the Los Gatos ProjectDistrict was negotiated and a final contract ratified in April 2006 between MPR and La Cuesta International S. A. de C.V. (Mexican(the Mexican subsidiary of La Cuesta International Inc.). Only minor field work was conducted during 2006-2007in 2006 and 2007 on the Los Gatos ProjectDistrict during the waiting period for the initial concession to be titled, and formal exploration activities and drilling were conducted by MPR from and after 2008.

      Exploration

      The Los Gatos Project is without known reserves and is exploratory in nature. The Los Gatos ProjectDistrict consists of three identified silver discoveries, discoveries—the Cerro Los Gatos Mine, the Esther deposit and the Amapola zones, deposit—and 1011 other identified prospectsmineralized zones with over 100150 kilometers of outcropping quartz and calcite veins.veins are also located in the Los Gatos District.

      In 2008,2007, MPR initiated its first phase of exploration in the Los Gatos ProjectDistrict area with a program of surface geological mapping and rock sampling covering approximately 60% of the original Los Gatos concession within the core of the claim block. This work, conducted through a local Mexico-based consulting group, Grupo Azta, identified in excess of 100 kilometers of strike length of quartz and calcite veins, many of which contained lead, zinc and silver mineralization. Of the 1,217 rock samples taken from surface outcrops of vein and wall rocks, 200 samples contained values in excess of 10 grams of silver per tonne.

      From June 2008 to October 2008, environmental permits were obtained, proposed drill areas were re-mapped and re-sampled, surface access rights were negotiated with local ranches, and drill access roads were constructed. In January 2009 and September 2009, reports and corresponding notices of activity were submitted to the Environmental Attorney Protection AgencySecretary of Environment and Natural Resources to cover the development of access roads and drill sites to drill 50 holes, along with a request to increase the number of drill holes to 250. Based on a report filed on December 5, 2011, the number of drill holes permitted on the Los Gatos ProjectDistrict was extended to 600 drill holes.

              Environmental baseline data collection began in May 2010 for the development of future environmental studies required for the project. Data on flora, fauna, water, air, climate, security and social impacts are generally collected on a routine basis for integration into future environmental studies required for the Los Gatos Project.

Results of the sampling identified new veins in the Esther zonedeposit and revealed four separate structures between the Esther deposit and the Cerro Los Gatos zones.Mine.

      Detailed topographic mapping has been created using Photosat, a Canadian contractor. The topography mapping was created at one meter, five meter, 10 meter and 50 meter contours from Geoeye®Geoeye® satellite coverage captured exclusively for the survey. Survey control points were established on the surface, with coordinates by total station in order to guarantee the accuracy of the survey.

      A detailed 3D Induced Polarization survey was conducted during July 2010 using SJ Geophysics, a contractor from Canada. Lines were initially spaced at 100 meters with stations every 25 meters, and later tightened to 50 meters by 25 meters. Results of the survey suggest a correlation between vein

In addition, the vein mineralization at the Esther zone suggestsdeposit suggested a similar relationship of high chargeability and low resistivity. The first holes to test the trends of mineralization from these surveys have successfully extended mineralization in both zones. As a result of the good correlation with mineralization, extensions of the surveys began in November 2010 inat both the Cerro Los Gatos Mine and Esther zones.deposit. Additionally, data is beingwas collected in the Amapola and San Agustin zones to determine the signature of mineralization in these new areas for drilling.

      Drilling

      As of August 2012, 345July 1, 2020, 739 exploration drill holes hadhave been completed by MPR for a total of 161,092in the Los Gatos District, totaling 259,060 meters.

      Drill sites are selected based on surface vein outcrops and geometric projections into the subsurface, as well as geochemical, geophysical and geological targets. Drilling is conducted using a wire line rig with diamond core capabilities. Holes begin with HQ size and are reduced, if necessary, to NQ and very rarely BQ, if difficult drilling conditions are encountered. Holes are surveyed with a Flexit EZ trac device at 50 meter intervals as the holes are completed. Surveys of drill hole surfacehole-collar coordinates locations are completed by a local contract topographer using a Topcon Total Station GTS-236W. All information pertinent to the drilling is stored in a master database in Microsoft Access®Access®. TetraTech has reviewed the drilling information to be used for modeling and found the database to be reasonably free of errors and appropriate for use in this report. Additional drilling at the Cerro Los Gatos zoneMine is aimed at upgrading the confidence of the resource and identifying mineralized extensions along strike and down dip.

      In addition to the drilling conducted at the Cerro Los Gatos Mine, the Esther deposit and the Amapola zones,deposit, MPR has conducted limited exploration drilling programs in ten other areas in the Los Gatos District which include Cieneguita, San Luis, Paula Adorada, San Agustin, Mezcalera, Torunos, Rodeo, Boca de Leon, EvaCieneguita, El Lince, El Rodeo, La Paula, Los Torunos Mezcalera, Ocelote, San Agustin, San Luis and El Lince.Wall-E/Ava. While anomalous levels of mineralization have been identified in each of these ten zones other than Wall-E/Ava, drilling data is too limited to speculate as to the presence of economic quantities of mineralization. Additional drilling will be required in each area to delineate the mineralization identified.

      The Company’s objectives at the Los Gatos Project through 2013 are to:

      expand the exploration drilling program;

      conduct social, environmental and technical work on the property with the objective of completing a pre-feasibility study on the Cerro Los Gatos, Esther and Amapola zones;

      perform additional in-fill drilling to further define mineralization at the Cerro Los Gatos, Esther and Amapola zones; and

      The Los Gatos ProjectDistrict hosts a series of quartz, quartz-calcite and calcite veins in at least eightfifteen separate vein systems that are exposed along a strike length of approximately 1230 kilometers and an outcrop belt width of

      approximately five kilometers. Vein width is generally in the order of one meter, but local wide zones up to eight meters in outcrop and true vein widths in excess of 30 meters have been identified by diamond drilling. Structurally, the veins form two sets, with north and northwest strikes and mostly steep dips. West/northwest trending fault and fracture zones probably reflect reactivated basement structures, whereas many of the north/northwest trending faults probably are associated with basin-and-range extension. Epithermal mineralization is associated with both phases of extension, so both trends have exploration potential; however, the basement architecture has overall control on the distribution of magmatic centers and hydrothermal systems.

      Mineralization at the Los Gatos ProjectDistrict is characterized by silver, lead, zinc and copper sulphides and their oxides, along with fluorite, manganese, barite and traces of gold associated with quartz and calcite veins. The veins vary in orientation from west-northwest to northwest to north-northwest to north-northeast and vary in thickness from one meter to eight meters outcrop, but with much greater true width at depth based upon diamond drilling. Study of the veins in hand specimen and thin section suggests that they are epithermal in origin and are likely of intermediate sulfidation composition, showing vein textures and gangue mineralogy that indicate a relatively high-level hydrothermal system in the boiling environment. Breccia with clasts of vein quartz indicates a protracted hydrothermal system during multiple faulting events, a positive sign for economic epithermal veins. It has been

              The Cerro Los Gatos is the most persistentMine vein system is persistent, with a general northwest trend dipping to the east, a mapped extension in the order of ten kilometers, and true widths of as much as eight30 meters and local associated veining up to 50 meters wide. Banded quartz veins and breccias are cemented by quartz, calcite and abundant manganese oxides (in surface outcrops).oxides. A study based on geological characteristics and silver-lead-zinc (arsenic-antimony-mercury) anomalous sections of the vein resulted in the discovery of the Los Gatos sub-horizontallistric-shaped mineralized horizon hosting the steeply to shallowly dipping mineralized-shoots at depth. Mineralization of interest is seen for approximately 2,500 meters in length and for an estimated average vertical extension in the order of 200 meters. High grade epithermal mineralization begins at a depth of around 100-150 meters. The reported average drilled true width of the structure is in the order of 8.9 meters. It has been interpreted that the top of the mineralized horizon at Los Gatos is generally located at an elevation of 1,3001,400 meters above sea level (masl) to 1,350 masl..

      Original exploration activities at the Esther vein system indicated the presence of a narrow quartz vein, less than one meter, with minor veining and silicification and noticeable lack of calcite. However, the presence of a small high-grade mineralized-shoot, probably 60 meters deep, attracted interest in the area. Drilling of this area also resulted in the discovery of the Esther mineralized-shoot, which has a known length of 800 meters for the main mineralized-shoot, as well as up to 1,200 meters of additional mineralized vein. The height of the mineralized interval is indicated by two drill holes to be in the order of 100 meters; most mineral intersections range in the order of two meters to eight meters, with a probable average slightly over three meters. It has been interpreted that the top of the favorable horizon at Esther is generally located about 120 meters below the surface.

      The Amapola zone is characterized by a seriesdeposit contains several vein systems at varying degrees of parallelstrike and dip that are the target of exploration. Currently, four of these veins comprise adequate Ag grade and thickness to be considered as mineralized material and geologically modeled. The four veins striking north to southinclude the Albita, Elizabeth, Cascajal and west-northwest to east-southeast with sub-vertical dip.Julia. The Amapola zone is located on the regional west-northwest trend of the Cerro Los Gatos Zone 4.5 km to the northwest, however the highest grade mineralization does not share the same strike orientation. Six mineralized veins have been identified in the Amapola zone from drilling, however most knownmineral resources are located inprincipally present on the Albita and Elizabeth veins, which are parallel and separated only bytogether comprise a few meters."corridor" of mineralization up to approximately 50 meters thick.

      Sampling, Analysis and AnalysisData Verification

      MPR has carried out sampling campaigns that have included surface, limited underground and core samples. Samples were taken by local crews under the supervision of either a geologist of MPR or one of their contractors. Sampling intervals were, in most cases, two meters, with local variations depending on vein geology, to a

      minimum of 0.8 meters where structures were found. Detailed sampling was carried out at intervals directed by geological criteria, with priority given to testing high-grade zones in the vein structures and attention also given to identifying possible mineralization in the wall rock and quartz stockwork veining.

      MPR established a sampling protocol, which was followed through the drilling campaign, that in summary includes: supervision by MPR personnel, with the verification of core handling, recovery, core accommodation and depth recording by the contractor; and core collection, measurement, core recovery, photographing, specific gravity, geotechnical information and sampling interval selection by MPR geologists.

      Detailed logging of the sample intervals is conducted once the core samples are sawed, with detailed descriptions and estimations of mineralogy and mineral content, hydrothermal alteration, veining and fracturing. Assay intervals are divided in two equal parts by diamond saw, with most sampling conducted on two meter intervals, except for specific vein intervals. Vein intervals are selected for more detailed sampling, with a minimum of 0.8 meters per interval in the sample and a maximum of two meters.


      Table of Contents

      Samples are collected in standard plastic sample bags and tagged with a unique sample number recorded for each interval. Samples are grouped by drill hole and transported by pickup truck to the ALS Chemex laboratories sample receiving location in Chihuahua City, Mexico. From the time the core samples leave the drill site to the time the samples are delivered to ALS Chemex, they are escorted and under the supervision of personnel from MPR.

      Samples are dried, crushed and pulverized by ALS Chemex in Chihuahua City. Assay orders are delivered to the lab, and a copy of the receipt obtained is filed and registered in MPR’sMPR's database. Sample pulps are then shipped by ALS Chemex to their laboratory in Vancouver, Canada for ICP analyses of silver, base metals and trace elements using a four-acid digestion technique. Gold assays are also completed using fire assay-AA preparation on 30-gram splits of the sample material.

      ALS Chemex has developed and implemented at each of its locations a Quality Management System (QMS) designed to ensure the production of consistently reliable data. As a result, the lab has received, including its sample preparation section in Guadalajara, the ISO 9001:2000 QMS registration from QMI. The ALS Laboratory Vancouver branch has also been accredited as conforming to requirements of Canadian regulations in this matter.

      MPR has set up a Quality Assurance/Quality Control (QA/QC) program to monitor the drilling program at the Los Gatos Project,District, including the use of: (1) blanks (barren silica sand or barren andesitic flow material inserted wherever the geologist deems appropriate, but no less than one for every 40 samples focused on areas of higher metal values, which could lead to contamination); (2) standards are added every 20th20th sample (MPR has purchased 12 different standards from Rocklabs Ltd.); and (3) duplicates are also analyzed every 50 samples (each batch) by placing two sample tickets in the same sample bag and having the lab generate two pulps of the same sample for analysis.

      It is believed that core sampling is representative of mineralized intersections, with minor variations due to irregularities in mineralization, and that the QA/QC programs established by MPR and the sampling process follow industry standards and are adequate forsupport the estimation of mineral resource estimates.resource.

      A review was made of available information derived from previous exploration work. This information included geological and sampling reports, drill logs, as well as assay results. Verification consisted of a general review of geological characteristics of the main mineralized areas, shown by the MPR field checking of geological maps in all areas and of sampling procedures by MPR as well as a review of all vein intersections and discussions of detailed sample handling, sampling and security procedures established by MPR. The original locations of samples reviewed were located, although most require re-painting. Tetra Tech verified several drill hole location monuments with a handheld global positioning system.

      Tetra Tech has conducted sample verification to evaluate whether the samples selected by MPR for metallurgical and hardness testing were geologically representative of the material in the mine plan. The review found that: samples were well selected with respect to various grades, alterations and host rock; there was no apparent metal domaining or zoning in the deposit; and that most of the samples fromfall within the bulk of the grade distributions and sampling of the higher-grade material has been accounted.

      Mineral Resource Estimates—Cerro Los Gatos Mine, Esther and Amapola areas. 36 samples from Cerro Los Gatos and 16 samples from Amapola were chosen. Care was taken to select a fair distribution of samples based on the deposit. Core samples were split in MPR’s sample preparation facilities in San Jose del Sitio from the remaining core halves. Tetra Tech has concluded that based on the results of the verification, MPR’s sampling can be considered reliable.

              For the Cerro Los Gatos Mine, a cut-off grade of 150 grams silver equivalent/tonne was estimated using generalized parameters, including the following: $40/tonne for mining costs; $20/tonne for processing costs; $4/tonne for general and administrative costs; 83% recovery at an assumed price of $18.00/oz silver; 92% recovery at an assumed price of $0.92/lb lead; and 77% recovery at an assumed price of $1.01/lb zinc. For the Esther deposit, a cut-off grade of 100 grams silver equivalent/tonne was estimated using generalized parameters, including the following: $40/tonne for mining costs; $20/tonne for processing costs; $3/tonne for general and administrative costs; 100% recovery at an assumed price of $22.30/oz silver; 95% recovery at an assumed price of $0.97/lb lead; and 88% recovery at an assumed price of $0.91/lb zinc. For the Amapola deposit, a cut-off grade of 100 grams silver equivalent/tonne was estimated using generalized parameters, including the following: $40/tonne for mining costs; $20/tonne for processing costs; $3/tonne for general and administrative costs; 100% recovery at an assumed price of $22.30/oz silver; 95% recovery at an assumed price of $0.97/lb lead; and 88% recovery at an assumed price of $0.91/lb zinc.

              Projected revenues from the sale of silver, zinc and lead are based upon long-term consensus prices that were the averages of long-term forecast prices that MPR obtained from various financial institutions as of the effective date of the respective mineral resource estimates. As of the effective date of the respective mineral resource estimates, the long-term consensus prices reflected the best estimate of the sales price that may be realized in the future from the mineral resources. Gold and copper, being part of the epithermal system, are included in the Mineral Resource estimate as comparisons, however they have not been considered for purposes of determining the Ag/Eq cut-off grade since copper in the final concentrates sold would not receive any payment and gold revenue is estimated at only 2.78% of the payable metal.

      The Tonnetonne and grade estimates in the block model are based on drill hole assay sample intervals. The vein widths are constrained by three-tensionalthree-dimensional solids and have not been diluted.

      To be classified as mineralized material, a block        Sample intervals were composited to two meters, which is the mode sample length. Compositing was requiredinitiated and terminated at the top and bottom of continuous selected vein samples, resulting composites were permitted to be estimated using data points inside a search ellipsoid ranging from 125one to 130 meters. The search ellipsoid long axistwo meters in length and intervals less than one meter were rejected. As part of the Kriging process, composite influence was additionally weighted by interval length to provide further normalization. Compositing greater than two meters was determined using variogram analysis. In addition to the search ellipsoid range, samples were requirednot to be sourced fromappropriate because three-meter composites would cause samples to be split and four-meter composites are too large to represent the vein across drip in some areas. At the Amapola deposit, ordinary Kriging was used. A single Kriging pass was made on each of the four veins and their secondary nearest neighbor. An inferred pass was only made for the Albita and Elizabeth veins. Similarly, at least two drill holes per estimatethe Esther deposit, grade estimation was completed using ordinary Kriging. An initial Kriging pass was made on each of the three veins and havefollowed by a relative Kriging error of less than 1.04 for Amapola, 1.25 for Esther and 1.45 for Cerro Los Gatos.secondary nearest inferred pass.

      Density of each block was determined from measured density samples within the mineralized zones and Kriged as a block attribute.

      Mineral Reserve Estimates—Cerro Los Gatos Mine

              The mineral reserve estimates include the portion of the measured and indicated resource that can be mined economically. Economic criteria and mining constraints (based on the selected mining methods) are applied to the resource blocks to define mineable blocks. Mineral reserves are determined after applying dilution and recovery factors to these mineable blocks.

              Mineral reserve estimates are calculated from the mine plan created from the September 2019 resource update. The mineral reserve estimates contained in the Los Gatos Technical Report have an effective date of July 1, 2020 and exclude 655,746 tonnes of material that has been mined through June 30, 2020. The table below shows the reconciliation of mined tonnage and grades to the modeled reserve depletion for this time period, with differences resulting primarily from different sequencing of stopes and variances in ore tonnes:

See Section 15 of the Los Gatos Technical Report.

      Mineral Processing and Metallurgical Testing

              The Cerro Los Gatos Mine is a silver-lead-zinc deposit with relatively complex mineralogy. Upon review of the metallurgical testing data, it was clear that the Cerro Los Gatos Mine mineralization responded well to a conventional sequential silver-lead-zinc flotation processing. Zinc rougher flotation tailings and zinc first cleaner scavenger tailings are combined to become the final tailings. Tailings thickener underflow (100%) is pumped to a cyanide destruction facility. Currently, all tailings are disposed of in the tailings storage facility. Once the backfill plant is in operation, and after detox, 40% of final tailings will be pumped to the backfill plant and the remaining 60% will be pumped to the tailings storage facility. Operational results have indicated that additional removal of fluorine will be required. Additional floatation cells have been added to the lead and zinc circuits, with a goal of reducing the fluorine in the final concentrates.

              The expected grades and recoveries for lead, zinc, and silver to individual flotation concentrates were further investigated by a pilot plant program at SGS Lakefield using a sample composed of a bulk sample accessed by an underground decline into the orebody. The results of that program are being

      finalized but preliminary indications generally support the study grade and recovery estimates provided herein.

              Positive lead and silver flotation results were achieved from the SGS Vancouver Metallurgical Lab. The final lead cleaner concentrates of the locked cycle tests averaged 60.9% lead at 5,404 g/t silver at average recoveries of 89% lead and 68.7% silver. The zinc cleaner concentrates averaged 54.2% at an average recovery of 66.0% due to the high willemite content.

      Mining Operations

      Cerro Los Gatos Mine Underground Development

      GRAPHIC

              The underground mine design supports a steady-state production rate of 2,500 tpd of ore. Over the life of the mine, the mine is projected to produce 81 million ounces of silver, 69 thousand ounces of gold, 878 million pounds of zinc, and 499 million pounds of lead in concentrate. The sequence of mining began with the Central Zone, which had already been accessed via the existing decline developed down to the 1400 Level. The bulk of the Central Zone will be mined using the drift-and-fill method, as the dips, widths and thicknesses of the vein structures are amenable to this mining method.

              The Northwest Zone is being mined concurrently with the Central Zone via longhole stoping methods with sublevels developed at 20 meter vertical intervals. Portions of the Northwest Zone that are thicker than nine meters (footwall to hanging wall) will be mined using transverse longhole mining. Areas that are less than nine meters in width will be mined using longitudinal longhole mining. In the Central Zone, operations confirmed that backfill deficiencies caused unstable conditions on the hanging-wall zone, as it was experienced in stope 625, where the stability problems created blocks causing the support to yield. The predicted conditions in this zone have been accurate. In the Northwest Zone, the operating geotechnical conditions have been better than the anticipated conditions. This has allowed the excavation of bigger dimensions in the stope length (more than 12 meters), and the planned activities have considered excavating more in the vertical dimension of the stope (25 meters height). Some of the stability problems found in this zone are mainly due to drilling deficiencies, which have reached areas near the hanging-wall fault zone. The 3D modeling of the Southeast Zone did not identify any issues except for potential hanging wall failure.

              Modern trackless mobile equipment is being employed for most mining activities. Load-Haul-Dump ("LHD") trucks and dedicated underground trucks are used for ore/waste loading and transport from the underground workings through an internal ramp system and portal that connects all levels to surface. Ongoing waste development to sustain the 2,500 tpd production rate averages approximately 211 meters/month during the production period.


      Table of Contents

              Based on the deposit geometry and anticipated geomechanical conditions, underground mining of the Cerro Los Gatos Mine resource will incorporate both longhole and drift-and-fill mining methods. The existing exploration decline from surface will be extended to provide primary access and delivery of services. The ramp will also be used for haulage of ore and waste from the underground operations.

      Processing and Recovery Operations

              The processing facility is designed to treat 2,500 tpd of silver, lead and zinc material at an operational availability of 92%. The processing flow sheet for the project is a standard flow sheet commonly used in the mining industry, including conventional flotation recovery methods typical for lead-zinc material. The production plant has been constructed and adjustments will continue to optimize performance. Additional flotation cells have been installed to remove fluorine from the concentrates.

              Run-of-mine ("ROM") material is crushed in a primary jaw crusher located near the underground mine portal. It is then conveyed to the processing facilities where it is ground to 80% finer than 45 microns in a semi-autogenous grinding and ball milling circuit. The ore is further processed in a flotation circuit, consisting of lead flotation followed by zinc flotation. The majority of the silver will be recovered in the lead flotation circuit and some silver will also be collected in the zinc flotation circuit. Lead sulfide is recovered in a rougher flotation bank, producing a concentrate that is then upgraded to smelter specifications in three stages of cleaning. Tails from the lead flotation section is then conditioned for zinc sulfide flotation. The process scheme for zinc flotation also includes a rougher bank and five stages of cleaning to produce smelter-grade zinc concentrates. For both lead and zinc sections, the rougher flotation concentrates are reground to 80% finer than 25 microns prior to cleaner flotation to liberate the sulfides for further upgrading. An additional deep-froth flotation cell has been added to the zinc circuit, and one additional deep-froth flotation cell will be added to the zinc and lead circuits during 2020, to remove more fluorine, a deleterious mineral for sales. Both final lead and zinc concentrates are thickened, filtered and stored in concentrate storage facilities prior to being loaded in trucks for shipment.

      Infrastructure, Permitting and Compliance Activities

              In addition to the recently constructed Cerro Los Gatos Mine processing plant and other facilities, we have a field camp located in nearby San José del Sitio, a community of approximately 264 persons, with electrical and water services, an elementary school and basic health services. Water resources in the region are mostly related to the Conchos River Basin, which includes the San Pedro, San Francisco de Borja and Satevó River Sub-Basins. Locally, there are significant amounts of water, with shallow groundwater recorded from most exploration drilling conducted by us.

              Underground development of the Cerro Los Gatos Mine commenced in 2015 and surface infrastructure development commenced in 2017. All significant surface infrastructure was completed in mid-2019 and the Cerro Los Gatos Mine commenced production of lead and zinc concentrates on September 1, 2019. The Cerro Los Gatos Mine processing plant is currently designed for 2,500 tpd capacity and the grinding circuit was engineered for expansion to 3,000 tpd in the future.

              The Cerro Los Gatos Mine is located in the Municipality of Satevó, Chihuahua, Mexico, approximately 160 kilometers southwest of the state capital of Chihuahua City and approximately 8 kilometers west of San José del Sitio, Chihuahua. The access road from Chihuahua, Mexico is newly paved. A portion of the road from San José del Sitio was rerouted to the mine site to minimize interference with the stream that runs near the mine property.

              Construction of required infrastructure has been completed, including administration offices, mine dry, fuel storage, mine maintenance shop, jaw crushing station, dome-covered crushed ore stockpile, process plant (including grinding circuit, flotation circuit, concentrate and tailing thickeners, concentrate

      loadout and tailings detoxification), tailing storage facility, electrical substation, 66 kilometers of power line connecting high voltage to the grid substation at San Francisco de Borja, assay lab, mill maintenance, dewatering wells and water cooling and distribution system, and residential camps and associated infrastructure.

              The camps consist of structural steel pre-engineered buildings capable of housing over 350 people. The camps include kitchen and cafeteria, laundry, infirmary, and other buildings required to maintain this facility. Emergency power is provided for in the camp to deliver 100% backup in the event of a power outage.

              The entire project is served by satellite-dish based internet and telephone communications.

              Power to the site is supplied via a 115 kV utility transmission line. This originates from the San Francisco de Borja substation in Satevó (Chihuahua), where a 115 kV connection has recently been installed.

              All raw water to meet potable and non-potable water demand is supplied by groundwater pumped from dewatering wells. The well water is cooled from 50°C to 40°C prior to use. Sewage water treatment systems were included to handle waste as required on the project.

              Storage and management of landfill disposal is housed in a single building, separated into two zones—one for non-hazardous waste and a second zone for hazardous waste. The hazardous waste is to be collected and disposal by a certified and authorized company per Mexican regulations.

              In 2008, we negotiated surface access rights with local ranch owners and obtained environmental permits for drilling. In April 2012, we entered into a mine and land access agreement with the local community, the Ejido La Esperanza (the "Ejido"), which provides annual land access with a renewal fee of $11,200. We also maintain an easement contract for 30 years with the Ejido for the access road to the mine.

              On December 12, 2016, MPR submitted an environmental impact statement to the Mexican Secretary of Environment and Natural Resources, which regulates the environmental aspects of mining projects and issued the permits once such statement is approved. The statement was approved in 2017. We also received approval for the permits for land use, authorization and approval for initiation of construction of mining workings and infrastructure and official alignment and number from the Municipality of Satevó, Chihuahua in June and July of 2018. In May 2019, we received approval for Environmental Unique License for the production of 2,500 tpd.

              On July 17, 2017, the Mexican Secretary of Environment and Natural Resources approved a mining exploitation project in Satevó, Chihuahua to develop work and activities (site preparation, construction, operation and others) needed to mine and explore the area. The authorized permit period is for 24 years ending July 17, 2041, with the possibility to extend for a similar period. Additionally, on September 4, 2017, we received the permitting to develop, construct and operate a project named Línea Eléctrica 115 KV Los Gatos, which consists of opening an 18-meter wide corridor over 58.0 kilometers. This project affects an area of 105 hectares to support the power lines in the municipalities of San Francisco de Borja and San Javier Satevó, Chihuahua. The authorized permit period is until September 4, 2037. We also received the relevant change of land use permitting to remove forest vegetation and fertile soil in an area of 390.6972 hectares to prepare the site and construct the infrastructure required for the mining exploitation of the Los Gatos project which expires November 1, 2020, with the option to extend.

              We are committed to safety at the Cerro Los Gatos Mine. The Cerro Los Gatos mine is built to higher environmental standards than required by Mexican law, with a fully-lined tailings impoundment facility and enclosure of the conveyors and ore storage dome. We also use state-of-the-art rescue

      Exploration, Development, and Production

              Concentrate production is currently achieving quality specifications and expected grades. The Cerro Los Gatos Mine is expected to produce, on average, 12.2 million payable silver equivalent ounces annually through the existing mine life (or 6.3 million payable silver equivalent ounces annually on a 51.5% basis), with an attractive, low-cost AISC profile. In addition to the goal of achieving the plant's 2,500 tpd design capacity, we intend to use a portion of the proceeds from this offering to complete a feasibility study, prepared in accordance with the SEC Mining Modernization Rules and NI 43-101, to expand the Cerro Los Gatos Mine production rate to 3,000 tpd. If feasible, we expect the LGJV to complete the expansion within the next three to four years.

AISC calculated as sum of total operating costs, treatment and refining charges, penalties, transportation and freight, royalties and capital costs for each year. See Section 22 of the Los Gatos Technical Report. The Los Gatos Technical Report has an effective date of July 1, 2020. The mineral resource estimates contained in the Los Gatos Technical Report have an effective date of September 6, 2019. The mineral reserve estimates and the economic analysis contained in the Los Gatos Technical Report have an effective date of July 1, 2020 and exclude 655,746 tonnes of material that has been mined through June 30, 2020. For a discussion of the mineral resource estimates and mineral reserve estimates contained in the Los Gatos Technical Report, see "—The Los Gatos District—Mineral Resource Estimates—Cerro Los Gatos Mine, Esther and Amapola Deposits" and "—The Los Gatos District—Mineral Reserve Estimates—Cerro Los Gatos Mine." For a discussion of the assumed capital and operating costs in the Los Gatos Technical Report, see "—The Los Gatos District—Capital and Operating Costs." Based on production to date, we believe that the Cerro Los Gatos Mine has the potential to produce up to 7.2 million ounces of silver equivalent on a 100% basis (3.7 million ounces of silver equivalent on a 51.5% basis) in fiscal year 2020.

              We believe there is widespread mineralization potential beyond the Cerro Los Gatos Mine, the Esther and Amapola deposits and the 11 other mineralized materialzones, as more than 85% of the land position has yet to be drilled.

              The current resources are significant, but we believe that additional resource potential remains in the immediate area. Drill testing of other high-priority targets within the Los Gatos District has been relatively limited given our focus on delineation of reserves at, and construction of, the Cerro Los Gatos Mine. As a result, the highly prospective Los Gatos District remains underexplored. Drilling at the Esther deposit to date has demonstrated good grade continuity along the system and characteristics similar to that identified during preliminary work at the Cerro Los Gatos Mine. Following potentially positive results from infill drilling at the Esther and Amapola deposits, we expect to update the resources and perform a scoping study to determine if these two deposit areas could generate economic production, representing further upside potential for the broader Los Gatos District.

              We expect to perform additional definition drilling to expand the Southeast and Northwest zones of the Cerro Los Gatos Mine and to perform additional drilling to expand the Esther and Amapola deposits, which remain open to extensions at depth. In addition to the Cerro Los Gatos Mine, the Esther deposit and the Amapola deposit, we have identified 11 other mineralized zones defined by

      Other Mexican Properties

      The Company owns or controls a portfolio of 19 other exploration properties in Mexico covering an area of 420,895 hectares, with significant additional hectares under application for mineral concession. There are three projects underway with significant drill results, El Doctor (skarn and vein silver) in Oaxaca, Santa Valeria (epithermal vein silver) in Chihuahua and Zacatlan (disseminated and vein silver) in Puebla. Additional drilling is planned at these projects as well as additional targets through 2013. The Company is planning sufficient drilling in an effort to outline continuous geometry of mineralization at El Doctor, Santa Valeria and Zacatlan which could lead to initial estimates of mineralized material.

      Other notable projects include Mine Grande (vein and disseminated silver), Los Cuates (epithermal vein silver), Las Coloradas (vein and replacement silver), San Fermin (skarn and vein silver), San Jose de Minas (disseminated and vein silver) and Pablito (epithermal vein silver). All these properties are without known reserves and are exploratory in nature. The locations of these properties are indicated in the map below.

Larger regional companies such as Coeur d’Alene Mines Corporation, Hecla Mining Company, Stillwater Mining Company and Kinross Gold Corporation in the Pacific Northwest can offer better employment terms as compared to smaller companies such as the Company.us.

      The Company        We also competescompete for mine service companies, in particularsuch as project coordinators and drilling companies. Potential suppliers may choose to provide better terms and scheduling to larger companies in the industry due to the scale and scope of their operations.

      Environmental, Health and Safety Matters

      The Company is        We are subject to stringent and complex environmental laws, regulations and permits in the various jurisdictions in which it operates. These requirements are a significant consideration for the Companyus as itsour operations involve, or may in the future involve, among other things, the removal, extraction and processing of natural resources, emission and discharge of materials into the environment, remediation of soil and groundwater contamination, workplace health and safety, reclamation and closure of waste impoundments and other properties, and handling, storage, transport and disposal of wastes and hazardous materials. Compliance with these laws, regulations and permits can require substantial capital or operating costs or otherwise delay, limit or prohibit the Company’sour development or future operation of itsour properties. These laws, regulations and permits, and the enforcement and interpretation thereof, change frequently and generally have become more stringent over time. If the Company violateswe violate these environmental requirements it may be subject to litigation, fines or other sanctions, including the revocation of permits and suspension of operations. Pursuant to such requirements, the Companywe also may be subject to inspections or reviews by governmental authorities.

      Permits and Approvals

      Numerous environmental permits and approvals are required for the Company’s current and future operations. Many of these permits are subject to renewal from time to time and can impose strict conditions, requirements or obligations on, or otherwise delay or prohibit, certain activities.

      In particular, the Company is subject to permitting requirements in connection with water discharges at the Sunshine Mine. The Company operates under a National Pollutant Discharge Elimination System, or NPDES, permit that expired in 1996 but has been administratively extended. The Company applied to the U.S. Environmental Protection Agency for a renewal of its NPDES permit in July 2007 and is awaiting a response. The NPDES permit covers, among other matters, the waste streams from mining and ore concentrating operations at the Sunshine Mine and drainage water from discontinued mining operations. Beginning in the 1990s, the predecessor began allowing the lower mined-out levels of the mine to flood, which resulted in elevated iron and manganese concentrations in the mine water. In the future, more stringent limits could be

      imposed under the NPDES permit, whether as part of the permit renewal process or otherwise. The Company believes that it will incur significant costs to upgrade the existing wastewater treatment facility to meet more stringent permit limits, including those relating to total dissolved solids.

      To obtain, maintain and renew its environmental permits, the Companywe may be required to conduct environmental studies and collect and present to governmental authorities data pertaining to the potential impact that its current or future operations may have upon the environment. For example, in order to commence underground exploration activities at the Cerro Los Gatos Project, the Company will needMine, we were required to submit an environmental analysis to the applicable governmental authorities. In May 2010, the Companywe began collection ofcollecting the environmental baseline data for the Cerro Los Gatos Project. The Company expects that data collected on flora, fauna, water, air, climate, securityMine and social impacts will be integrated into future environmental studies required forreceived the Los Gatos Project.

      The Company will require additional permits and approvals to conduct future exploration, development and processing activities, including at both the Sunshine Mine property and the Los Gatos Project. Any failure to obtain, maintain or renew required permits, or other permitting delays or conditions, may delay, limit or prohibit its current or future operations.permit in 2015.

      Hazardous Substances and Waste Management

      The Company        We could be liable for environmental contamination at or from itsour or its predecessors’our predecessors' currently or formerly owned or operated properties or third-party waste disposal sites. Certain environmental laws impose joint and several strict liability for releases of hazardous substances at such properties or sites, without regard to fault or the legality of the original conduct. A generator of waste can be held responsible for contamination resulting from the treatment or disposal of such waste at any off-site location (such as a landfill), regardless of whether the generator arranged for the treatment or disposal of the waste in compliance with applicable laws. Costs associated with liability for removal or remediation of contamination or damage to natural resources could be substantial and liability under these laws may attach without regard to whether the responsible party knew of, or was responsible for, the presence of the contaminants. In addition to potentially significant investigation and remediation costs, such matters can give rise to claims from governmental authorities and other third parties for fines or penalties, natural resource damages, personal injury and property damage.

      In connection with the Sunshine Mine, the Company is involved in the Bunker Hill Superfund Site. Pursuant to a 2001 Consent Decree that resolved certain liabilities arising under the U.S. Comprehensive Environmental Response, Compensation and Liability Act relating to the Bunker Hill site, the Company is required to pay to the U.S. government and the Coeur d’Alene Indian tribe between a 0% (at a silver price below $6 per ounce) and 7% (at a silver price of $10 per ounce or higher) NSR royalty. This Consent Decree did not resolve all liabilities associated with the Bunker Hill site, including any liability for contamination at or migrating from the Company’s owned, leased or operated properties, which are located within the Bunker Hill Superfund Site. In addition, the U.S. Department of Justice has notified the Company that it believes that the Company is not entitled to the liability protections under the Consent Decree. The Company may incur additional costs, liabilities or obligations in connection with the Bunker Hill site.

      The tailings pond at the Sunshine Mine currently receives mine water and process water discharges from the Company’s operations, as well as similar discharges from the nearby Crescent Mine. The Company expects that the capacity of the tailings pond as currently configured will be sufficient for approximately ten years after commercial production resumes and that additional capacity may be added thereafter by increasing the height of the pond dam.

      The Company is required to maintain financial assurances for certain future closure obligations, including closure obligations with respect to the tailings pond at the Sunshine Mine. As of December 31, 2012, the Company has recorded an asset retirement obligation of approximately $862 that reflects the estimated present value of future closure obligations.

      Mine Health and Safety Laws

      The Federal Mine Safety and Health Act of 1977 and the Occupational Safety and Health Act of 1970 impose stringent safety and health standards on all aspects of mining operations at the Sunshine Mine property.

      Also, Idaho has state programs for mine safety and health regulation and enforcement. In addition, the Company’s        Our Mexican properties are subject to regulation by the Political Constitution of the Mexican United States, and are subject to various legislation in Mexico, including the Mining Law, the Federal Law of Waters, the Federal Labor Law, the Federal Law of Firearms and Explosives, the General Law


      Table of Contents

      on Ecological Balance and Environmental Protection and the Federal Law on Metrology Standards. Mining, environmental and labor authorities may inspect the Company’sour operations on a regular basis and issue various citations and orders when they believe a violation has occurred under the relevant statute. Regulations and the results of inspections, whether in the United States or Mexico, may have a significant effect on the Company’sour operating costs.

      Legislative and regulatory bodies at the federal and state levels, including MSHA and OSHA, have recently promulgated or proposed various new statutes, regulations and policies relating to mine safety and mine emergency issues. Although some new laws, regulations and policies are in place, these legislative and regulatory efforts are still ongoing.        At this time, it is not possible to predict the full effect that the new or proposed statutes, regulations and policies will have on the Company’sour operating costs, but it may increase its costs and those of its competitors.

      Other Environmental Laws

      The Company is        We are required to comply with numerous other foreign, federal, state and local environmental laws, regulations and permits in addition to those previously discussed. These additional requirements include, for example, the U.S. Emergency Planning and Community Right-to-Know Act and Resource Conservation and Recovery Act and various permits regulating road construction and drilling at the Company’s Los Gatos, El Doctor, Mina GrandeMexican properties.

              We endeavor to conduct our mining operations in compliance with all applicable laws and Zacatlan zones.regulations. However, because of extensive and comprehensive regulatory requirements, violations during mining operations occur from time to time in the industry.

      Facilities and Employees

      As discussed above, the Company owns        We own and leaseslease land at the Sunshine Mine property, the Los Gatos Project and the Company’sour other exploration properties in Mexico. The Company also leases its executive office spaceMexico and at 370 17th Street, Suite 3800, Denver, Colorado, which lease expires on July 31, 2017, subject to a renewal option.the Los Gatos District through our ownership interest in the LGJV.

      As of December 31, 2012, the CompanyJune 30, 2020, we had 5710 full-time employees in the United States and 8410 full-time employees in Mexico, and the LGJV had approximately 540 employees in Mexico. The Company also has a services agreement, which will continue following the offering, with The Electrum Group LLC and several consultantsWe believe that provide additional management, accounting and financial services. See “Certain Relationships and Related Party Transactions.” The Company believes that itsour employee relations are good and plansplan to continue to hire employees as itsour operations expand. The Company expects the number of employees to increase following the offering as it increases its exploration efforts and prepares to operate as a public company. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Operating Expenses—Exploration Expenses.”

      Legal Proceedings

      From time to time, the Companywe and our affiliates may become subject to various legal proceedings that are incidental to the ordinary conduct of its business. Although the Companywe cannot accurately predict the amount of any liability that may ultimately arise with respect to any of these matters, it makeswe make a provision for potential liabilities when it deemswe deem them probable and reasonably estimable. These provisions are based on current information and legal advice and may be adjusted from time to time according to developments.

      Stonehill Capital Management LLC See Note 10, "Commitments and Highwood Partners, LP, or the Lenders, as debtors-in-possession, or DIP, lenders to SPMI, a prior owner of the Sunshine Mine, have asserted a mortgage claim against certain of the property at the Sunshine Mine that the Company acquired from SPMIContingencies" in June 2010. The DIP financing loan was made in connection with SPMI’s bankruptcy in 2000, in the amount of $5 million, but the Lenders claim that they were owed $71.2 million as of March 31, 2011, including accrued interest and penalties, and further, that this

      amount continues to accrue interest at a compounded rate of 25%. Additionally, they are seeking an award of their attorneys’ fees and costs. The Company filed a complaint in the District Court of Shoshone County, Idaho, on September 23, 2010 to declare the alleged mortgage unenforceable. The Lenders filed an action before the same court to enforce the mortgage. The two actions have been consolidated. Following the conclusion of pre-trial discovery, the Company and the Lenders submitted motions for summary judgment, which were argued before the Court on April 17, 2012. The Court issued a written order on the motions on April 19, 2012, or the Order. In its Order, the Court partially denied and partially granted each parties’ motions, holding that the Lenders’ mortgage was generally enforceable but that the Lenders were obligated, under a prior 2003 agreement with SPMI and certain of its affiliates, to release their mortgage and other liens upon receipt of an amount, or the Net Proceeds, to be determined by the Court in a subsequent hearing. For the purpose of avoiding the cost and delay inherent in conducting a further hearing and to progress the case toward a final court judgment, the Parties have stipulated that the Net Proceeds owed are $2.725 million. At a status conference held on October 5, 2012, the Court refused the Lenders’ request to certify the Order as a final order, in light of certain remaining issues between the Lenders and another party. These issues do not involve the Company’s property. A hearing to resolve all such remaining issues was scheduled for November 7, 2012, but the parties involved engaged in settlement talks and requested an adjournment of the hearing until their settlement was complete. Following such settlement, the Court is expected to enter its final judgment after which both parties have the right to appeal the Court’s April 19, 2012 summary judgment order. A hearing to determine the possible award of attorneys’ fees and costs was heldour consolidated financial statements included elsewhere in this case on November 19, 2012, at which time the Court held that no party was entitled to its attorneys’ fees and costs. On February 20, 2013, the Court held a hearing to determine termsprospectus for additional information regarding our assessment of the final judgment, and a final judgment resolving the claims is expected in the near term. The Company does not believe that this matter is likely to have a material adverse effect on its operations or financial condition. Litigation is inherently unpredictable, however, and while the Company believes it has valid arguments and defenses should the matter be reviewed on appeal, there can be no assurance as to the ultimate outcome of this action.

      The Company is from time to time involved in various legal proceedingscontingencies related to its business. Except in the above-described proceeding, management does not believe that adverse decisions in any pending or threatened proceeding or that amounts that may be required to be paid by reason thereof will have a material adverse effectlegal matters.

      Diversity

      Board of Directors

              We have not adopted a formal policy with respect to the identification and nomination of women and of other diverse attributes on the Board of Directors. Establishing and implementing a policy regarding diversity and female representation on the Board of Directors will be an element that we will take into consideration going forward.


      Table of Contents

              There is currently one woman on the Board of Directors (representing 11% of the current directors) and the Board of Directors is committed to increasing the level of women on the Board of Directors as board turnover occurs from time to time, taking into account the skills, background, experience and knowledge desired at a particular time by the Board of Directors and its committees. Accordingly, consideration of the number of women who are directors, along with consideration of whether other diverse attributes are sufficiently represented on the Board of Directors, will be an important component of the selection process for new members of the Board of Directors going forward.

              The Compensation and Nominating Committee will, within the purview of its mandate, have the responsibility to take diversity into consideration as part of the overall director selection and nomination processes and to make the identification of female candidates a search criterion. Gender diversity on the Board of Directors will be achieved by continuously monitoring the level of female representation and, where appropriate, recruiting qualified female candidates to fill positions, as the need arises, through vacancies, growth or otherwise.

              The Board of Directors has not adopted a target regarding the number of women on the Board of Directors as the Board of Directors has determined that a target would not be the most effective way of ensuring greater diversity. The Board of Directors will however consider the appropriateness of adopting such a target in the future.

      Executive Officer Positions

              In appointing individuals to executive officer positions, we weigh a number of factors, including skills, experience and personal attributes required for the position along with the level of female representation within our senior management team. There are currently no women occupying an executive officer position within the Company (0% of the executive officers). We are, however, committed to increasing the gender diversity of our executive officers going forward.

              We have not adopted a target for the number of women in executive officer positions. The Board of Directors believes the most effective way to achieve greater diversity in our senior management team is to identify high-potential women within the organization and work with them to ensure they develop the skills, acquire the experience and have the opportunities necessary to eventually occupy executive officer positions. This includes taking action to build a culture of inclusion throughout the organization. The Board of Directors will, however, continue to evaluate the appropriateness of adopting targets in the future.

      Board Committees

      The Executive Committee will consist of Stephen OrrJanice Stairs (chair), William NatbonyIgor Levental and Diana Walters.Stephen Orr.

      2012 Annual BonusStock Option Grants

      Under the terms of their employment agreements, the NEOs are eligible to receive an        On May 3, 2019, we granted annual bonus with a target amount of 50% of their base salary and a maximum payout of 100% of their base salary, depending on the achievement of certain performance metrics set by the Compensation and Nominating Committee.

      For the 2012 annual bonus, the Compensation and Nominating Committee has set performance metrics for each of our executive officers in the following categories: capital management, project development, exploration and resource management, asset management, safety and environmental. The performance metrics were reasonably challenging and represented a general set of goals for the Company,stock option awards in recognition of the fact that all members of the senior management are part of a team of which each member can contribute toward achieving those goals. The standards and relative weightings of the metrics differed among members of senior managementservices performed in fiscal year 2019 to reflect the different responsibilities carried by each executive.

      Each performance metric was assigned a weight, and to the extent practicable, all metrics were measured by objective standards. Following the end of the 2012 performance year, the Compensation and Nominating Committee assessed the achievement of each metric, which achievement ranged from 90% to 200%. For each

      metric, an achievement below 90% resulted in a zero payout with respect to that metric and a 100% achievement resulted in a target payout with respect to that metric. If all standards in a metric were not only achieved but substantially exceeded, then the Compensation and Nominating Committee may, in its discretion, recommend an achievement for that metric that exceeds 100% (to up to 200%), in which case the payout with respect to that metric would exceed target. Two performance metrics were removed from the calculation due to changing priorities during the 2012 performance year, and three new performance metrics in the categories involving comprehensive resource modeling, mine plan acceleration and production improvement, and discovery of new zones of mineralization were added to reflect significant efforts devoted to, and achievement in, these areas during the 2012 performance year. A deduction was also made in the total achievement score as a result of the mine fire that occurred in February 2012.

      On February 22, 2013, the Board approved the total achievement score and resulting payout determined from the assessment made by the Compensation and Nominating Committee described above, subject to an adjustment in the total achievement scores of Messrs. Orr and Johnson pending the result of a strategic objective that is targeted for completion in 2013 and any other adjustment in the payout to each NEO to be determined by the Board.

      The final payout to each NEO will be in the form of Deferred Stock Units. Currently, we expect each NEO to receive Deferred Stock Units for his 2012 bonus in the following amounts:

Section 203 prohibits a person who acquires more than 15% but less than 85% of all classes of our outstanding voting stock without the approval of our Board of Directors from merging or combining with us for a period of three years, unless the merger or combination is approved by a two-thirds vote of the shares not owned by such person. These provisions would apply even if the proposed merger or acquisition could be considered beneficial by some stockholders.

      Limits on Special Meetings

      Special meetings of the stockholdersshareholders may be called at any time only by the secretary at the direction of our Board of Directors pursuant to a resolution adopted by the Board of DirectorsDirectors.

      Choice of Forum

              Our Amended and Restated Certificate of Incorporation will provide that the Court of Chancery of the State of Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a breach of fiduciary duty; (iii) any action asserting a claim against us arising under the Delaware General Corporation Law; and (iv) any action asserting a claim against us that is governed by Electrum until it ceasesthe internal affairs doctrine. This provision does not apply to own more than 50%suits brought to enforce a duty or liability created by the Securities Act, the Exchange Act or any other claim for which the U.S. federal courts have exclusive jurisdiction. Our Amended and Restated Certificate of Incorporation will further provide that the federal district courts of the United States will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.

              Our Amended and Restated Certificate of Incorporation will also provide that any person or entity purchasing or otherwise acquiring or holding any interest in shares of our outstanding common stock.capital stock will be deemed to have notice of and to have consented to these choice of forum provisions. These exclusive forum provisions may limit a stockholder's ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers, and other employees, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder.

              While Delaware courts have determined that choice of forum provisions are facially valid, it is possible that a court of law in another jurisdiction could rule that the choice of forum provisions to be contained in our Amended and Restated Certificate of Incorporation are inapplicable or unenforceable if they are challenged in a proceeding or otherwise. If a court were to find the choice of forum provision in our Amended and Restated Certificate of Incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions.

      Amendments to our Governing Documents

      Generally, the amendment of our Amended and Restated Certificate of Incorporation requires approval by our Board of Directors and the vote of holders of more than 50%66.67% of the votes entitled to be cast by the outstanding capital stock in the election of our Board of Directors (which amount shall be raised to 66 2/3% of our outstanding capital stock following the time that Electrum ceases to own more than 50% of our outstanding common stock).Directors. Any amendment to our Amended and Restated Bylaws requires the approval of either a majority of our Board of Directors or holders of more than 50%66.7% of the votes entitled to be cast by the outstanding capital stock in the election of our Board of Directors (which amount shall be raised to 66 2/3% of our outstanding capital stock following the time that Electrum ceases to own more than 50% of our outstanding common stock).Directors.

      Board of Directors

      Initially, our        Our Board of Directors will consist of a single class of directors each serving one year terms. Following Electrum ceasing to own more than 50% of our outstanding common stock, our Board of Directorsand directors will be divided into three classes of directors, with each class as nearly equal in number as possible, serving staggered three year termsserve until a successor is duly elected and qualified or until a director's earlier death, removal or resignation (other than directors that may be elected by holders of our preferred shares, if any).

      Our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws provide that at such date that Electrum ceases to own more than 50% of our outstanding common stock, directors may be removed only for cause and only by the affirmative vote of the holders of 66 2/3%66.67% of our outstanding voting stock, voting together as a single class, unless approved by our Board of Directors, in which case such removal for cause shall require the affirmative vote of the holders of more than 50% of our outstanding voting stock, voting together as a single class. Prior to that date, directors may be removed by holders of a majority of our outstanding voting stock, voting together as a single class. Our Amended and Restated Certificate of Incorporation and our Amended and Restated Bylaws provide that any vacancy on our Board of Directors, including a vacancy resulting from an enlargement of our Board of Directors, may be filled by vote of a majority of our directors then in office. Furthermore, our Amended and Restated Certificate of Incorporation provides that the authorized number of directors may be changed only by resolution of our Board of Directors.

      Delaware Business Combination Statute

              We will elect to be subject to Section 203 of the Delaware General Corporation Law, which regulates corporate acquisitions. Section 203 prevents an "interested stockholder," which is defined generally as a person owning 15% or more of a corporation's voting stock, or any affiliate or associate of that person, from engaging in a broad range of "business combinations" with the corporation for three years after becoming an interested stockholder unless:

        Listingthe board of directors of the corporation had previously approved either the business combination or the transaction that resulted in the stockholder's becoming an interested stockholder;

        upon completion of the transaction that resulted in the stockholder's becoming an interested stockholder, that person owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, other than statutorily excluded shares; or

        following the transaction in which that person became an interested stockholder, the business combination is approved by the board of directors of the corporation and holders of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

              Under Section 203, the restrictions described above also do not apply to specific business combinations proposed by an interested stockholder following the announcement or notification of designated extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation's directors, if such extraordinary transaction is approved or not opposed by a majority of the directors who were directors prior to any person becoming an

      The Company will listinterested stockholder during the commonprevious three years or were recommended for election or elected to succeed such directors by a majority of such directors.

              Section 203 may make it more difficult for a person who would be an interested stockholder to effect various business combinations with a corporation for a three-year period. Section 203 also may have the effect of preventing changes in our management and could make it more difficult to accomplish transactions which our stockholders may otherwise deem to be in their best interests.

      Anti-Takeover Effects of Some Provisions

              Some provisions of our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws could make the following more difficult:

        acquisition of control of us by means of a proxy contest or otherwise, or

        removal of our incumbent officers and directors.

In the event that we do paymake distributions of cash or other property, those distributions will constitute dividends dividends you receive onfor U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed our current and accumulated earnings and profits, they will constitute a return of capital, which will first reduce your basis in our common stock, but not below zero, and then will be treated as gain from the sale of our common stock, as described below under "—Gain on Disposition of Our Common Stock."

              Dividends paid to you generally will be subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty. In order to obtain a reduced rate of withholding (subject to the discussion below under "—FATCA"), you mustwill be required to provide ana properly executed applicable Internal Revenue Service ("IRS") Form W-8BENW-8 certifying your entitlement to benefits under a treaty.

      Gain on Disposition of Our Common Stock

      You        Subject to the discussion below under "—Information Reporting and Backup Withholding," you generally will generally not be subject to U.S. federal income or withholding tax on gain realized on a sale or other taxable disposition of our common stock unless either (i) unless:

        the gain is effectively connected with your conduct of a trade or business in the United States and,(and, if required by an applicable income tax treaty, is also attributable to a permanent establishment or fixed base maintained by you in the United States,States), or (ii) the gain is subject to tax under the rules that apply to the disposition of the stock of

        we are or have been a “U.S."United States real property holding corporation,”corporation" (a "USRPHC"), as described below, at any time within the five-year period preceding the disposition or your holding period, whichever period is shorter, and our common stock has ceased to be regularly traded on an established securities market prior to the beginning of the calendar year in which the sale or disposition occurs.

              We believe that we are not, and do not anticipate becoming, a USRPHC.

      Gain        If you recognize gain on a sale or other disposition of our common stock that is effectively connected with your conduct of a trade or business in the United States will be subject to regular U.S.(and if required by an applicable income tax as iftreaty, is attributable to a permanent establishment or fixed base maintained by you werein the United States), you will generally be taxed on such gain in the same manner as a U.S. resident, subjectperson.

      A corporation is generally a USRPHC if 50% or more of the fair market value of its real property assets and its other assets used or held for use in a trade or business consist of U.S. real property interests, as defined in the Code and applicable regulations. Based on our estimates of the current relative fair market values of our U.S. real property interests and other assets, we believe we are not currently a USRPHC. However, both because the determination of the value of our mineral assets is uncertain and requires the use of subjective estimates, and because the relative fair market values of our assets will likely fluctuate over time (based on, for example, the results of the exploration and development of our properties), there can be no assurance that we are not, or will not become, a USRPHC. Even if weyou are a USRPHC, for so long as our common stock is regularly traded on an established securities market (such as the NYSE), you will not recognize taxable gain on a sale of our common stock under the rules applicable to USRPHCs unless you actually or constructively own more than 5% of our common stock at any time during the five-year period ending on the date of disposition or, if shorter, your holding period for our common stock. If our common stock was not considered to be regularly traded on an established securities market for purposes of these rules, you would be subject to U.S. federal income tax on any gain recognized on the disposition of all or a portion of our common stock in generally the same manner as described above with respect to gain that is effectively connected with the conduct of a trade or business in the United States.corporation.

Generally, our common stock will be capital property to a Holder provided the Holder does not acquire or hold our common stock in the course of carrying on a business or as part of an adventure or concern in the nature of trade.

      This summary is not applicable to (i) a purchaserHolder an interest in which is a “tax"tax shelter investment”investment", (ii) a purchaserHolder that is a “financial institution”"financial institution" for purposes of certain rules referred to as the mark-to-market rules, or (iii) a purchaserHolder that is a "specified financial institution", (iv) a Holder that is a partnership or exempt from tax under Part I of the Tax Act, (v) a Holder that reports its “Canadian"Canadian tax results”results" in a currency other than Canadian currency, or (vi) a Holder that has entered or will enter into, in respect of our common stock, a "synthetic disposition arrangement" or a "derivative forward agreement", each as defined in the Tax Act. Additional considerations, not discussed herein, may be applicable to a purchaserHolder that is a corporation that is, or becomes as part of a transaction or event or series of transactions or events that includes the acquisition of our common stock, controlled by a non-resident corporationperson or group of non-resident persons for the purposes of the foreign affiliate dumping rules in section 212.3 of the Tax Act. Such purchasersHolders should consult their own tax advisors.

      This summary is based on the current provisions of the Tax Act, and an understanding of the current administrative policies and assessing practices of the Canada Revenue Agency published in writing prior to the date hereof. This summary takes into account all specific proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, or the Proposed Amendments, and assumes that all Proposed Amendments will be enacted in the form proposed. However, no assurances can be given that the Proposed Amendments will be enacted as proposed, or at all. This summary does not otherwise take into account or anticipate any changes in law or administrative policy or assessing practice whether by legislative, administrative or judicial action nor does it take into account tax legislation or considerations of any province, territory or foreign jurisdiction, which may differ from those discussed herein.

      This summary is of a general nature only and is not, and is not intended to be, legal or tax advice to any prospective purchaser or holder of our common stock. This summary is not exhaustive of all Canadian federal income tax considerations. Accordingly, prospective purchasers of our common stock should consult their own tax advisors having regard to their own particular circumstances.

      Currency Conversion

      Generally, for purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of our common stock must be converted into Canadian dollars based on the exchange rates as determined in accordance with the Tax Act. The amount of dividends required to be included in the income of, and capital gains or capital losses realized by, a Holder may be affected by fluctuations in the Canadian / U.S. dollar exchange rate.

      Dividends

      A Holder will be required to include in computing its income for a taxation year the amount of any dividends received on our common stock. In the case of a Holder that is an individual, such dividends willnot be subject to the gross-up and dividend tax credit rules applicable to taxable


      Table of Contents

      dividends received from taxable Canadian corporations. A Holder that is a corporation willnot be entitled to deduct the amount of such dividends in computing its taxable income. The full amount of the dividends, including amounts deducted for U.S. withholding tax, if any, in respect of the dividends must be included in income. To the extent U.S. withholding tax is paid in respect of dividends paid on our common stock, the amount of such tax generally will be eligible for foreign tax credit or deduction treatment subject to the detailed rules and limitations under the Tax Act.

      Holders are advised to consult their own tax advisors with respect to the availability of a credit or deduction to them having regard to their particular circumstances.

      Dispositions

      Generally, on a disposition or deemed disposition of a share of our common stock, a Holder will realize a capital gain (or capital loss) equal to the amount, if any, by which the proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base to the Holder of the share immediately before the disposition or deemed disposition.

      The adjusted cost base to the Holder of a share of our common stock acquired pursuant to this offering will be determined by averaging the cost of such share with the adjusted cost base immediately before the time of acquisition of all other shares of our common stock owned by the Holder as capital property immediately before that time, if any.

      Generally, a Holder is required to include in computing its income for a taxation year one-half of the amount of any capital gain, or a taxable capital gain, realized in the year. Subject to and in accordance with the provisions of the Tax Act, a Holder is required to deduct one-half of the amount of any capital loss, or an allowable capital loss, realized in a taxation year from taxable capital gains realized by the Holder in the year and allowable capital losses in excess of taxable capital gains for the year may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any subsequent taxation year against net taxable capital gains realized in such years. Capital gains realized by a Holder that is an individual or trust, other than certain specified trusts, may give rise to a liability for alternative minimum tax under the Tax Act.

      To the extent U.S. tax is paid in respect of capital gains realized on the disposition or deemed disposition of a share of our common stock, the amount of such tax generally will be eligible for foreign tax credit treatment subject to the detailed rules and limitations under the Tax Act. Holders are advised to consult their own tax advisors with respect to the availability of a credit to them having regard to their particular circumstances.

      Offshore Investment Fund Property

      The rules of the Tax Act with respect to acquisition of offshore investment fund property, as would be amended by certain Proposed Amendments in Bill C-48,contains provisions (the "OIF Rules") which received its First Reading on November 21, 2012 and which is currently at Second Reading in the House of Commons, may, in certain circumstances, require a Holder to include an amount in income in each taxation year in respect of the acquisition and holding of our common stock, if (1) the value of such common stock may reasonably be considered to be derived, directly or indirectly, primarily from portfolio investments in: (i) shares of the capital stock of one or more corporations,

      (ii) indebtedness or annuities, (iii) interests in one or more corporations, trusts, partnerships, organizations, funds or entities, (iv) commodities, (v) real estate, (vi) Canadian or foreign resource properties, (vii) currency of a country other than Canada, (viii) rights or options to acquire or dispose of any of the foregoing, or (ix) any combination of the foregoing or, collectively, Investment Assets. We are of the view that our common stock should not(collectively, "Investment Assets") and (2) it may reasonably be an offshore investment fund property.

      Furthermore, in order for these rules to apply to a Holder in respect of our common stock, if, contrary to our view, it is an offshore investment fund property, it must be reasonable to concludeconcluded that one of the main reasons for the Holder acquiring, holding or holdinghaving shares of our common stock was to derive a benefit from portfolio investments in Investment Assets in such a manner that the taxes, if any, on the income, profits and gains from such Investment Assets for any particular year are significantly less than the tax that would have been applicable under Part I of the Tax Act if the income, profits and gains had been earned directly by the Holder.

              In making the determination under point (2) in the preceding paragraph, the OIF Rules provide that regard must be had to all of the circumstances, including (i) the nature, organization and operation of any non-resident entity, including the Company, and the form of, and the terms and conditions governing, the Holder's interest in, or connection with, any such non-resident entity, (ii) the extent to which any income, profit and gains that may reasonably be considered to be earned or accrued, whether directly or indirectly, for the benefit of any non-resident entity, including the Company, are subject to an income or profits tax that is significantly less than the income tax that would be applicable to such income, profits and gains if they were earned directly by the Holder, and (iii) the extent to which any income, profits and gains of any non-resident entity, including the Company, for any fiscal period are distributed in that or the immediately following fiscal period.

              If applicable, the OIF Rules generally require a Holder to include in the Holder's income for each taxation year in which such Holder owns our common stock the amount, if any, by which (i) the total of all amounts each of which is the product obtained when the Holder's "designated cost" (as defined in the Tax Act) of our common stock at the end of a month in the year is multiplied by 1/12 of the aggregate of the prescribed rate of interest for the period including that month plus two percentage points exceeds (ii) any dividends or other amounts included in computing such Holder's income for the year (other than a capital gain) from our common stock determined without reference to the OIF Rules. Any amount required to be included in computing a Holder's income in respect of our common stock under these provisions will be added to the adjusted cost base and the designated cost of our common stock to the Holder.

              The CRA has taken the position that the term "portfolio investment" should be given a broad interpretation. Notwithstanding this interpretation, we do not believe that the value of shares of our common stock should be regarded as being derived, directly or indirectly, primarily from portfolio investments in Investment Assets, though the CRA may take a different view. However, if the term "portfolio investment" should be given a broad interpretation, and even if the value of shares of our common stock may reasonably be considered to be derived, directly or indirectly, primarily from portfolio investments in Investment Assets, the OIF Rules will apply to a Holder only if it is reasonable to conclude that one of the main reasons for the Holder acquiring, holding or having our common stock was to derive a benefit from Investment Assets in such a manner that the taxes, if any, on the income, profits and gains from such Investment Assets for any particular year are significantly less than the tax that would have been applicable under Part I of the Tax Act if the income, profits and gains had been earned directly by the Holder.


      Table of Contents

      These rulesOIF Rules are complex and their application depends, in part, on the reasons for a Holder acquiring or holding our common stock. Holders are urged to consult their own tax advisors regarding the application and consequences of these rules in their own particular circumstances.

      Additional Refundable Tax

              A Holder that is, throughout its taxation year, a "Canadian-controlled private corporation" (as defined in the Tax Act) may be subject to pay a refundable tax on its "aggregate investment income" (as defined in the Tax Act), including amounts in respect of net taxable capital gains and certain dividends.

      Foreign Property Information Reporting

      In general, a Holder that is a “specified"specified Canadian entity”entity" for a taxation year or fiscal period and whose total cost amount of “specified"specified foreign property”property" (as such terms are defined in the Tax Act) including our common stock at any time in the taxation year or fiscal period exceeds CAD $100,000 will be required to file an information return for the taxation year or fiscal period disclosing certain prescribed information. Subject to certain exceptions, a taxpayer resident in Canada will generally be a specified Canadian entity. Our common stock will come within the definition of “specified"specified foreign property”property" for the purposes of the Tax Act. Penalties will apply where a Holder fails to file the required information return in respect of such Holder's "specified foreign property" on a timely basis in accordance with the Tax Act.

      In the 2010 Federal Budget, the Minister of Finance proposed to expand the existing reporting requirements with respect to “specified foreign property” so that more detailed information is available for audit use. Revised legislation reflecting such proposal has not yet been released.The reporting rules in the Tax Act are complex and this summary does not purport to explain all circumstances in which reporting may be required.

      Holders should consult their own tax advisors regarding whether they must comply with these reporting requirements including any expansion thereof pursuant to the above-mentioned 2010 Federal Budget proposal.requirements.

      Price Stabilization, Short Positions

      In connection with this offering, the underwriters may engage in activities that stabilize, maintain or otherwise affect the price of our common stock during and after this offering, including:

        stabilizing transactions;



      short sales;

      Table of Contents

        purchases to cover positions created by short sales;



      imposition of penalty bids; and



      syndicate covering transactions.

      Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of our common stock. These transactions may also include making short sales of our common stock, which involve the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering. Short sales may be “covered"covered short sales," which are short positions in an amount not greater than the underwriters’underwriters' over-allotment option referred to above, or may be “naked"naked short sales," which are short positions in excess of that amount.

      The underwriters may close out any covered short position by either exercising their over-allotment option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option.

      The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchased in this offering. Any naked short position would form part of the underwriters’ overallocationunderwriters' over-allocation position.

      The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of that underwriter in stabilizing or short covering transactions.

      As a result of these activities, the price of our common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. The underwriters may carry out these transactions on the New York Stock Exchange,NYSE, the Toronto Stock Exchange,TSX, other stock exchanges, in the over-the-counter market or otherwise. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of the shares.

      Determination of Offering Price

      Prior to this offering, there was no public market for our common stock. The initial public offering price will be determined by negotiation by us and the representatives of the underwriters. The principal factors to be considered in determining the initial public offering price include:

        the information set forth in this prospectus and otherwise available to the representatives;



      our history and prospects and the history and prospects for the industry in which we compete;



      our past and present financial performance and an assessment of our management;



      our prospects for future earnings and the present state of our development;



      the general condition of the securities market at the time of this offering;



      the recent market prices of, and demand for, publicly traded common stock of generally comparable companies; and



      other factors deemed relevant by the underwriters and us.

This material has been found to contain a sufficient amount of mineralization of an average grade of metal or metals to have economic potential that warrants further exploration evaluation. While this material is not currently or may never be classified as ore reserves, it is reported as mineralized material only if the potential exists for reclassification into the reserves category. This material cannot be classified in the reserves category until final technical, economic and legal factors have been determined. Under the SEC’s standards, a mineral deposit does not qualify as a reserve unless it can be economically and legally extracted at the time of reserve determination and it constitutes a proven or probable reserve (as defined below).Canadian Securities Administrators.

      “Ore”"NSR" means Net Smelter Return: the proceeds returned from the smelter and/or refinery to the mine owner less certain costs.

The degree of assurance, although lower than that for proven reserves, is high enough to assume continuity between points of observation.

      “Proven Reserve”is a portion of a mineral deposit that can be extracted or produced economically and legallydemonstrate, at the time of the reserve determination. The quantity of a proven reserve is computed from dimensions revealed in outcrops, trenches, workings or drill holes; grade and/or quality are computed from the results of detailed sampling and the sites for inspections, sampling and measurement are spaced so closely and the geologic character is so well definedreporting, that size, shape, depth and mineral content of a proven reserve is well-established.economic extraction can be justified.

      “Reclamation”"Reclamation"is the process by which lands disturbed as a result of mining activity are modified to support beneficial land use.

      Los Gatos was incorporated as a “shelf” holding company under the laws of Bermuda on April 24, 2006 for the purpose of coordinating the activities of subsidiaries exploring for deposits of precious and related metals and was substantially owned by CGT Management Ltd. (a limited liability company incorporated in Bermuda) (“CGT”).        The Company intends to realize value from its Los Gatos exploration portfolio over time through selective exploration/development, sale or joint ventures with third parties, as determined from time to time. The Company’sCompany's primary Mexico exploration efforts are focused on the advancementoperation of the Los Gatos Joint Venture ("LGJV") in Chihuahua Mexico with its joint venture partner, Dowa Metals and Mining Co., Ltd. ("Dowa"), which commenced production on September 1, 2019. As of December 31, 2019, the LGJV ownership is 51.5% SSMRC and 48.5% Dowa.

              On January 1, 2015, the Company entered into the LGJV to develop the Los Gatos project in northern Mexico, through("LGP") with Dowa. The LGJV operating entities consist of Minera Plata Real S. de R.L. de C.V. (“MPR”C.V ("MPR"), Operaciones San Jose del Plata S. de R.L. de C.V. and Servicios San Jose del Plata S. de R.L. de C.V. (collectively the "LGJV Entities"). The LGJV completed an advanced definitional drilling and decline development program in 2016 and completed a wholly-owned subsidiaryfeasibility study in January 2017. Dowa completed its $50,000 funding requirement on April 1, 2016; thereby initially acquiring a 30% interest in the LGJV and the right to purchase future zinc-concentrate production at market rates.

              In July 2017, the LGJV entered into a loan agreement (the "Term Loan") with Dowa whereby the LGJV could borrow up to $210,000 for LGP development, with a maturity date of December 29, 2027. Interest on the Term Loan accrues daily at LIBOR plus 2.35%, but the interest is added to the amount borrowed for repayment monthly until December 29, 2019. During 2018, the LGJV paid Dowa a $4,200 closing fee. Commencing June 30, 2021, 14 consecutive semi-annual equal payments of the Company.

      aggregate principal and capitalized interest begin. The Term Loan also requires additional principal payments equal to 70% of the LGJV excess cash flows (as defined). As of December 31, 2019, the LGJV had $221,900 outstanding, including $11,900 of interest, under the Term Loan. SSMRC is a 70% guarantor of the Term Loan should the LGJV not be able to meet its obligations under this loan agreement.

              In January 2018, the LGJV entered into a loan agreement (the "Dowa MPR Loan") with Dowa whereby the LGJV could borrow up to $65,700 to continue LGP development. Interest on this loan accrues daily at LIBOR plus 1.5% and is added to the amount borrowed. As of December 31, 2018, the LGJV had $67,800 outstanding, including $2,100 of interest, under the Dowa MPR Loan. In May 2019, the Company contributed $18,200 to the LGJV to provide funding for a partial repayment of

In May 2019, the Dowa MPR Loan was fully extinguished with a principal and interest payment of $18,200 and the conversion of the remaining principal and interest of $50,737 to additional Dowa ownership in the LGJV entities. Due to the natureLGJV ownership dilution, the Company recognized a dilution loss on affiliates of $11,231 in May 2019. Subsequent to this transaction the ownership of the Company’s activitiesLGJV entities is 51.5% SSMRC and 48.5% Dowa.

              As of December 31, 2019, the LGJV had $60,000 of principal and $8 of interest due under a working capital facility agreement ("WCF") entered into with Dowa in May 2019. The WCF bears interest at LIBOR plus 3.0% and matures June 28, 2021. The LGJV paid interest of $1,419 under this facility for the Sunshine Mine and Los Gatos exploration projects ityear ended December 31, 2019. SSMRC is deemeda 70% guarantor of the WCF should the LGJV be unable to be an exploration stage company.meet its obligations under this loan agreement.

              During 2019 and 2018, the LGJV entered into various equipment loan agreements, with repayment over four years at interest rates ranging from 5.76% to 8.67%, to finance a portion of mining equipment purchases. SSMRC has guaranteed the payment of all obligations, including accrued interest, under the equipment loan agreements.

      Mexico—Exploration

              The Company's other regional Mexico exploration efforts are conducted through its wholly-owned subsidiary, Minera Luz del Sol S. de R.L. de C.V. ("MLS").

      Liquidity

              The Company has a history of operating losses and cash outflows from operations which are both expected to continue. Based on the Company's current cash flow forecasts, there is an expected cash shortfall within one year of the issuance date of the financial statements. As a result, the Company received a financial support commitment for $18,000 from its primary shareholder, Electrum Silver US LLC, to ensure the Company is able to satisfy its obligations as a going concern through June 26, 2021. The Company will need to raise additional funds through the issuance of debt or equity to refinance or otherwise retire obligations, or to satisfy the guarantee of the LGJV WCF, as they come due after June 26, 2021. The ability to raise capital is dependent on certain matters that are outside of the Company's control, and it may not be successful in raising sufficient funds, which could lead to an event of default.

      2. Summary of Significant Accounting Policies (Continued)

      reviewed periodically for other-than-temporary decline in value. The Company's investment in the LGJV Entities is presented as Investment in affiliates in the consolidated balance sheet. The basis difference between the carrying amount of the investment in affiliates and the Company's equity in the LGJV Entities' net assets is due to value of the LGJV mineral resources. This basis difference is amortized on a units of production basis as the mineral resource is produced.

              The Company incurs certain costs on behalf of the LGJV, primarily related to a project development loan arrangement fee. The Company's proportional share of such costs are reported as an investment in affiliate and the residual costs, related to Dowa's proportional ownership, are reported in the statement of loss as arrangement fees.

      Use of estimates

      The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include mineral properties; environmental reclamation and closure obligations; valuation of stock and stock options; valuation allowances for deferred tax assets; and the fair value of financial instruments.

      Functional currency and translation of foreign currencies

      The U.S. dollar is the functional currency of the Company and its subsidiaries. Monetary assets and liabilities denominated in foreign currencies are translated intoto U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting gains or losses reported in foreign exchange (gain) loss in the computationstatement of net loss. Non-monetary assets and liabilities are translated at historical exchange rates. Expenses and other income and expense items denominated in foreign currencies are translated into U.S. dollars at average exchange rates, except for amortization which is translated at historical exchange rates.

      Cash and cash equivalents

      The Company considers all highly liquid short-term investments with a maturity of three months or less when purchased to be cash equivalents. Restricted cash, included in other current assets, consists of cash and investments which are held as collateral for a letter of credit and other extensions of credit. Restricted cash is included in other current assets.

      Investments

      Investment securities consist of publicly-traded equity securities. Short-term investments include investments with maturities greater than three months, but not exceeding 12 months. Long-term investments include investments with maturities greater than 12 months. The Company classifies its equity securities that have readily determinable fair values as available-for-sale securities. At December 31, 2012, the Company held $129 of short-term available for sale securities with an original cost of $85.

      Available-for-sale securities are recorded at fair value. Unrealized holding gains and losses, net of the related tax effect, on available-for-sale securities are excluded from earnings and are reported as a separate component of accumulated other comprehensive income until realized. Realized gains and losses from the sale of available-for-sale securities are determined on a specific-identification basis.

      2.Summary of Significant Accounting Policies—Continued

      A decline in the market value of any available-for-sale security below cost deemed to be other than temporary results in an impairment charge in the computation of net loss. To determine if an impairment is other than temporary, the Company considers all available information relevant to the collectability of the security, including past events, current conditions, and reasonable and supportable forecasts when developing estimate of cash flows expected to be collected.

      Property, plant and equipment

      Mineral property acquisition costs are recorded at cost and are deferred until the viability of the property is determined. Exploration, mineral property evaluation, option payments, related acquisition costs for mineral properties acquired under an option agreement, general overhead, administrative and holding costs to maintain a property on a care and maintenance basis are expensed in the period they are incurred. When a mineral property is determined to have proven and probable reserves, subsequent development costs are capitalized to mineral properties. For acquired mineral properties the Company allocates the acquisition cost to proven and probable reserves and value beyond proven and probable reserves. When mineral properties are developed and operations commence, the Company expects capitalized costs to beare charged to operations using the units-of-production method over proven and probable reserves. Upon abandonment or sale of a mineral property, all capitalized costs relating to the specific property are written offremoved in the period abandoned or sold and a gain or loss is recognized.

      Property, plant and equipment are recorded at cost. Amortization onof plant and equipment is calculated on the straight-line method over the estimated useful lives of the assets. The estimated useful lives of plant and equipment and buildings and improvements range from 10 to 20 years. The estimated useful lives of furniture, fixtures and computers range from 3three to 10 years.

      Impairment of long-lived assets

      Long-lived assets, such as property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. If circumstances requiredrequire a long-lived asset or asset group to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various

      Reclamation and remediation costs (assetAsset retirement obligations)obligations

      The Company has asset retirement obligations (“ARO”("ARO") arising from regulatory requirements to perform certain property and asset retirement activities at the end of the respective asset life. An ARO is recognized when incurred and is initially measured at fair value and subsequently adjusted for accretion expense and changes in the amount or timing of the estimated cash flows. The corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’sasset's remaining useful life. The ARO is based on when spending for an existing environmental disturbance is expected to occur.

      The Company estimates grant date fair value using the Black-Scholes option-pricing model using the grant date share price, estimated amounts for volatility of the Company’sCompany's stock, the expected life of the awards, the fair value of the underlying shares, the risk-free interest rate and the expected dividend yield. The related expense is included as a component of either exploration, pre-development or general and administrative expense over the requisite service period of the award.

      Net loss per share

      Pro-forma basic loss per share and diluted loss per share are computed by dividing net loss available to common stockholders by the pro-forma weighted-average number of shares outstanding for respective periods presented. The stock options have been excluded from the calculation of pro-forma dilutive earnings per share as their effect would be anti-dilutive. In accordance with Financial Accounting Standards Board Accounting Standards Codification (“ASC”) earnings per share guidance, the Company has retroactively adjusted the predecessor shares and capital outstanding to common-stock equivalent shares outstanding to determine the weighted-average number of shares outstanding for the periods presented. Changes in ownership interests during any period are weighted for the portion of the period the shares were deemed outstanding. Accordingly, the Company calculated the pro-forma weighted-average number of shares, on a common-stock-equivalent shares basis, for all reporting periods based on the following:

      1.Retroactively converted the Los Gatos ordinary and preferred shares outstanding to common-stock-equivalent shares outstanding of Sunshine Silver, at a conversion ratio of 0.15517;

      Income taxes

      Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company records interest related to unrecognized tax benefits in interest expense and penalties in income tax expense.

      On February 22, 2011, Los Gatos entered into an Agreement and Plan of Merger and Amalgamation (“Merger Plan”) with Sunshine Silver. Pursuant to the Merger Plan, on March 1, 2011, Los Gatos merged and was amalgamated with and into Sunshine Silver and the separate corporate existence of Los Gatos ceased. Each issued and outstanding Preferred Share and each issued and outstanding Ordinary Share was converted into approximately 0.15517 shares of par value $0.001 per share common stock of Sunshine Silver. The merger did not affect the shares of Sunshine Silver’s common stock existing before the merger.

      In addition, as a result of the Merger Plan, existing outstanding options to purchase one share of Los Gatos Ordinary Shares were converted by operation of law into an option to purchase approximately 0.15517 shares of Sunshine Silver common stock at an exercise price of $2.32 per share.

      4.Acquisition of the Sunshine Mine

      On May 11, 2010, the Company, through its wholly owned subsidiary SOP, acquired the net assets of Sterling’s Idaho Sunshine Mine by purchase through Sterling’s bankruptcy proceedings. Included in this purchase was Sterling’s mine lease with Sunshine Precious Metals, Inc. (“SPMI”). In July 2010, SOP exercised the option in the lease to buy the Sunshine Mine and facilities from SPMI.

      The Sunshine Mine is a past-producing mine. The Sunshine Mine suspended operations in 2008 and remains in a pre-development status. The mine facility includes extensive underground workings including shafts, levels, raises and ramp systems.

      The total consideration paid in cash was comprised of a) $23,500 for the net assets acquired and liabilities assumed and b) $5,750 for the right, title and interest acquired from SPMI. The payment for the lease was recorded in property, plant and equipment, net in the Company’s consolidated balance sheet at acquisition date. The acquisition was accounted for as a business combination. The purchase price of $29,250 was allocated to the following assets and liabilities using the estimated fair values of assets acquired and liabilities assumed at the acquisition date:

      Pursuant to the acquisition of the Sunshine Mine, the Company acquired the right to purchase, or have Sterling dissolve, all of the issued and outstanding common stock of Sterling for a payment of $500, subject to the completion of the Sterling bankruptcy proceedings. The Company exercised this right in August 2011 and purchased substantially all of the issued and outstanding common stock of Sterling for $500. The Company calculated the fair value of the August 2011 payment as of the May 2010 acquisition date. A discount rate of 6.14% was determined based on a review of comparable corporate bond yields as of the acquisition date.

      The results of the operations of the Sunshine Mine have been included in the Company’s consolidated statement of loss and comprehensive loss since the date of acquisition. The Company incurred $2,100 in acquisition costs related to the Sunshine mine acquisition. The Company follows the business combination accounting guidance related to acquisition-related costs and expenses these costs as incurred. The acquisition-related costs for the Sunshine Mine acquisition are included in general and administrative costs in the consolidated statement of loss and comprehensive loss for the year ended December 31, 2010.

All 106,616,318 Preferred Shares were issued to CGT in payment of the then outstanding advance of $527 and a reduction of long-term debt payable to CGT of $539. In addition, on October 2, 2009, Los Gatos issued 1,383,682 Ordinary Shares to CGT in payment of long term debt payable to CGT of $14.

      two vendors; and 3) 4,771,318 shares to Tigris Intl. In addition, individuals associated with various related entities purchased 11,425,956 Ordinary Shares for $114. The December 31, 2009 stock subscription receivable of $114 was paid in full on January 28, 2010.

      Certain of the Ordinary Shares issued are subject to agreements which contain a purchase option by the entity (or an affiliate of the entity) at which the respective shareholder is employed or is providing services, as the case may be. In case of termination of employment or the service relationship prior to five years from the initial vesting date set forth in each shareholder’s share purchase agreement or share award agreement, the shareholder can receive from the option holder, at the option holder’s option, payment for the shares amounting to 20% of the shares owned multiplied by the number of years from the initial vesting date to a maximum of 100% at a price determined by the Company’s board of directors. The purchase option ends five years from the initial vesting date. Additionally, certain other Ordinary Shares are subject to a partial purchase option. For the third and fourth vesting years, 40% and 20% of the shares, respectively, will be subject to the purchase option. Thereafter, these shares will no longer be subject to the purchase option.

      On June 30, 2010, the Company issued 174,949 Ordinary Shares for $2 to an employee of a related entity under the same terms as described above for Ordinary Shares. The Company recognized an additional $34 of expense to reflect the $0.20 fair value of the Ordinary Shares. The fair value was determined based on an enterprise value and option pricing model.

      On January 31, 2011, Los Gatos designated 14,542,512 unissued Ordinary Shares as Preferred Shares. On January 31, 2011, Los Gatos issued such Preferred Shares to CGT in full satisfaction of the then existing $31,198 (principal of $31,000 and interest of $198) amounts due to CGT.

      In addition, pursuant to the Merger Plan, the 6,727,561 options outstanding for the purchase of Los Gatos Ordinary Shares converted to options to purchase 1,043,938 common stock shares of Sunshine Silver at $2.32 per share on March 1, 2011.

      Stock Option Transactions

      On October 14, 2009, Los Gatos entered into stock option agreements with various individuals and entities that agreed to serve on its Advisory Board that provide for the purchase of 21,661,788 Ordinary Shares. These options vested on the date of the grant and had a stated exercise price of $0.36 per share expiring the earlier of October 14, 2019, or two years after an initial public offering. The stock options were valued using a Black-Scholes model.        The following assumptions were used to compute the fair value of the option grants:LGJV Personnel options as of December 31, 2019, 2018 and 2017:

The computation of the expected option life was determined based on a reasonable expectation of the option life prior to being exercised or forfeited. The risk-free interest rate assumption was based on the U.S. Treasury constant maturity yield at the date of the grant over the expected life of the option.

      For the year ended December 31, 2009, the Company recognized stock-based compensation of $65 related to these option grants. As of December 31, 2009, all 21,661,788 options were outstanding and exercisable

      During the year ended December 31, 2010, there were no stock options granted.

      In December 2010, options to acquire 14,934,227 Ordinary Shares were exercised by CGT, of which 14,616,139 options were acquired from an entity serving on the Advisory Board, at an exercise price of $0.36 per share resulting in $5,376 of capital contributions through reduction in related-party debt.

      At December 31, 2010, 6,727,561 options with an exercise price of $0.36 per share, expiring the earlier of October 14, 2019, or two years after an initial public offering, were outstanding.

      9. Fair Value Measurements

              

      11.Fair Value Measurements

      The Company establishes a framework for measuring the fair value of financial assets and liabilities and nonfinancial assets and liabilities which are measured at fair value on a recurring (annual) basis in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:

      Level 1:Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

      Level 2:Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

      Level 3:Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

      Financial Assets and Liabilities

      The following table summarizes the Company’s financial assets and liabilities measured at fair value on a recurring basis at December 31, 2012 and 2011 by respective level of the fair value hierarchy:

      11.Fair Value Measurements—Continued

      The Company’s short-term available for sale securities are classified within Level 1 of the fair value hierarchy. These securities are comprised of common stock, which are valued using quoted prices in active markets. The Company did not have any Level 2 or Level 3 financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2012 and 2011.

      Non-Financial Assets and Liabilities

      The Company discloses and recognizes its non-financial assets and liabilities, such as ARO, at fair value on a non-recurring basis. The estimated fair value for ARO is classified as Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions that market participants would use in the pricing of such liabilities without observable inputs and no market activity.

      Fair Value of Other Financial Instruments

      At December 31, 20122019 and 20112018 the Company’sCompany's other financial instruments consist of cash and cash equivalents, restricted cash, receivables, accounts payable and other current liabilities. The carrying amounts of these financial instruments approximate fair value due to their short maturities.

      Based upon the level of taxable income (loss) and projections of future taxable income (loss) over the periods which the deferred tax assets are deductible, management believes it is more likely than not that the Company will not realize the benefits of these deductible differences, and thus has recorded a valuation allowance against the net deferred tax asset balance of $58,463 and $30,732 as of December 31, 2012 and 2011, respectively. If the Company is profitable for a number of years and the prospects for the realization of the deferred tax assets are more likely than not, the Company will then reverse the valuation allowance and credit income tax expense.

      At December 31, 2012 the Company had $49,064 of net operating loss carryforwards in the United States expiring at various dates through 2032, and $53,491 of net operating loss carryforwards in Mexico which expire at various dates through 2022. Valuation allowances have been recorded on net operating loss carryforwards where the Company believes it is more likely than not that the net operating loss will not be realized. The Company will monitor the valuation on an ongoing basis and will make the appropriate adjustments as necessary should circumstances change.

      13.Income Taxes—Continued

      The Company has adopted the provisions of ASC 740-10,Income Taxes. The Company files income tax returns in the U.S., Mexico, and Idaho. The Company’s foreign assets and operations are owned by entities that have elected to be treated for U.S. tax purposes as unincorporated branches of a U.S. holding company and, as a result, the taxable income or loss and other tax attributes of such entities are included in the Company’s U.S. federal consolidated income tax return. The statute of limitations for tax returns filed in the U.S. and Mexico is three years and five years, respectively, from the date of filing. The Company’s 2012, 2011 and 2010 U.S. tax returns are subject to examinations by U.S. tax authorities until 2016, 2015 and 2014, respectively. The Company is no longer subject to examinations by Mexico tax authorities for years prior to 2008.

      As of December 31, 2012, the Company has not recognized any increases or decreases in unrecognized tax benefits, as it is more likely than not that all tax positions have a high probability of being upheld by the taxing authorities. The Company recognizes penalties and accrued interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. No such interest or penalties were recognized during the periods presented.

      14.Commitments and Contingencies

      The Company, in determining its accruals and disclosures with respect to loss contingencies, the Company will charge to income an estimated loss if information available prior to the issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the commitments and contingencies are expensed as incurred. If a loss contingency is not probable or reasonably

      estimable, disclosure of the loss contingency is made in the combined financial statements when it is at least reasonably possible that a material loss could be incurred.

      Environmental Contingencies

      The Company’sCompany's mining and exploration activities are subject to various laws, regulations and permits governing the protection of the environment. These laws, regulations and permits are continually changing and are generally becoming more restrictive. The Company has made, and expects to make in the future, expenditures to comply with such laws, regulations and permits, but cannot predict the full amount of such future expenditures.

      Other Contingencies

      Stonehill / Highwood Litigation

      Stonehill Capital Management LLC and Highwood Partners, LP (the “Lenders”), as debtors-in-possession, or (“DIP”), lenders to Sunshine Precious Metals, Inc. (“SPMI”), a prior owner of the Sunshine Mine, have asserted a mortgage claim against certain of the property at the Sunshine Mine that the Company acquired from SPMI in June 2010. The DIP financing loan was made in connection with SPMI’s bankruptcy in 2000, in the amount of $5,000, but the Lenders claim that they were owed $71,200 as of March 31, 2011 including accrued interest and penalties, and further, that this amount continues to accrue interest at a compounded rate of 25%. Additionally, they are seeking an award of their attorneys’ fees and costs. The Company filed a complaint in the District Court of Shoshone County, Idaho, on September 23, 2010 to declare the alleged mortgage unenforceable. The Lenders filed an action before the same court to enforce the mortgage. The two actions have been

      consolidated. Following the conclusion of pre-trial discovery, the Company and the Lenders submitted motions for summary judgment, which were argued before the court on April 17, 2012. The Court issued a written order on the motions on April 19, 2012 (the “Order”). In its Order, the Court partially denied and partially granted each party’s motions, holding that the Lenders’ mortgage was generally enforceable but that the Lenders were obligated, under a prior 2003 agreement with SPMI and certain of its affiliates, to release their mortgage and other liens upon receipt of an amount (the “Net Proceeds”) to be determined by the Court in a subsequent hearing. For the purpose of avoiding the cost and delay inherent in conducting a further hearing and to progress the case toward a final court judgment, the Parties have stipulated that the Net Proceeds owed are $2,725. At a status conference held on October 5, 2012, the Court refused the Lenders’ request to certify the Order as a final order, in light of certain remaining issues between the Lenders and another party. These issues do not involve the Company’s property. A hearing to resolve all such remaining issues was scheduled for November 7, 2012, but the parties involved engaged in settlement talks and requested an adjournment of the hearing until their settlement was complete. Following such settlement, the Court is expected to enter its final judgment after which both parties have the right to appeal the Court’s April 19, 2012 summary judgment order. A hearing to determine the possible award of attorneys’ fees and costs was held in this case on November 19, 2012, at which time the Court held that no party was entitled to its attorneys’ fees and costs. The Company intends to defend vigorously against the claims and does not believe that this matter is likely to have a material adverse effect on its operations or financial condition. Litigation is inherently unpredictable, however, and while the Company believes it has valid arguments and defenses should the matter be reviewed on appeal, there can be no assurance as to the ultimate outcome of this action.

      The Company is from time to time involved in various legal proceedings related to its business. Except in the above-described proceeding, managementManagement does not believe that adverse decisions in any pending or threatened proceeding or that amounts that may be required to be paid by reason thereof will have a material adverse effect of the Company’sCompany's financial condition or results of operations.

              As of December 31, 2019, the Company has not recognized any increases or decreases in unrecognized tax benefits, as it is more likely than not that all tax positions will be upheld by the taxing authorities. The Company reports tax penalties in income tax expense. No such penalties were recognized during the periods presented.

              Effective January 1, 2017, the Company's Mexico assets and operations are owned by entities that have elected to be treated for United States tax purposes as corporations and, as a result, the taxable income or loss and other tax attributes of such entities are stated separately from the Company's United States assets and operations and are not included in the Company's United States federal consolidated income tax return. The Company's other foreign assets and operations are owned by entities that have elected to be treated for U.S. tax purposes as unincorporated branches of a U.S. holding company and, as a result, the taxable income or loss and other tax attributes of such entities are included in the Company's U.S. federal consolidated income tax return.

              On December 22, 2017, the United States enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Act"). The Act makes broad changes to the United States tax code for corporations, including, but not limited to, (1) reducing the United States federal corporate tax rate from 35% to 21%; (2) allowing immediate deductibility for 100% of expenditures for qualified property through bonus depreciation; (3) eliminating the alternative minimum tax; and (4) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017.

      Independent Auditors' Report

      The Board of Managers
      Los Gatos Joint Venture:

              We have audited the accompanying combined financial statements of Los Gatos Joint Venture (the Company), which comprise the combined balance sheets as of December 31, 2019 and 2018, and the related combined statements of loss, combined statements of owners' capital, and cash flows for the years then ended, and the related notes to the combined financial statements.

      Management's Responsibility for the Financial Statements

              Management is responsible for the preparation and fair presentation of these combined financial statements in accordance with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of combined financial statements that are free from material misstatement, whether due to fraud or error.

      Auditors' Responsibility

              Our responsibility is to express an opinion on these combined financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined financial statements are free from material misstatement.

              An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the combined financial statements. The procedures selected depend on the auditors' judgment, including the assessment of the risks of material misstatement of the combined financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity's preparation and fair presentation of the combined financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the combined financial statements.

              We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

      Opinion

              In our opinion, the combined financial statements referred to above present fairly, in all material respects, the financial position of Los Gatos Joint Venture as of December 31, 2019 and 2018, and the results of its operations and its cash flows for the years then ended in accordance with U.S. generally accepted accounting principles.

      1. Description of Business and Basis of Preparation

              

      These combined financial statements represent the combined financial position and results of operations of the Los Gatos Joint Venture ("LGJV" or "the Company"). Unless the context otherwise requires, references to LGJV or the Company mean the Los Gatos Joint Venture.

              On January 1, 2015, the LGJV was established to develop the Los Gatos Project (LGP) in northern Mexico. The LGJV consists of Minera Plata Real S. de R.L. de C.V. ("MPR"), Operaciones San Jose de Plata S. de R.L. de C.V. and Servicios San Jose de Plata S. de R.L. de C.V. (collectively the "LGJV Entities"). Upon completion of their $50,000 funding to the LGJV, Dowa Metals & Mining, Ltd. ("Dowa") acquired a 30% interest in the LGJV Entities and the right to purchase future zinc-concentrate production at market rates. The remaining 70% interest in the LGJV entities was owned by Sunshine Silver Mining & Refining Corporation ("SSMRC"). The ownership of the LGJV Entities as of December 31, 2019 is 51.5% SSMRC and 48.5% Dowa, see footnote 9 for additional detail on LGJV Entities ownership changes.

      15.Segment Information—Continued

              In 2016, the LGJV completed an advanced definition drilling program and began decline development to provide the necessary data to complete a feasibility study. Prior to completing the feasibility study, the Company was in the exploration stage. The January 12, 2017 feasibility study ("Feasibility Study") demonstrated the economic viability of the LGP, and during the first quarter of 2017, the Company commenced the $316,000 LGP development.

      2. Summary of Significant Accounting Policies

      Risks and uncertainties

              As a mining company, the Company's revenue, profitability and future rate of growth are substantially dependent on prevailing prices for silver, zinc, lead and gold. Historically, the commodity markets have been quite volatile, and there can be no assurance that commodity prices will not be subject to wide fluctuations in the future. A substantial or extended decline in commodity prices could have a material adverse effect on the Company's financial position, results of operations, cash flows, and the quantities of reserves the Company can economically produce. The carrying value of the Company's property, plant and equipment, mine development, inventories and stockpiles are particularly sensitive to the outlook for commodity prices. A substantial or extended decline in the Company's price outlook could result in material impairment charges related to these assets. Additionally, changes in other factors such as changes in mine plans, increases in costs, geotechnical failures, and changes in social, environmental or regulatory requirements can adversely affect the Company's ability to recover its investment in certain assets and result in impairment charges.

      16.Sunshine Mine Fire

              The Company has considered and assessed the risk resulting from its concentrate sales arrangements with its customers. In the event that the Company's relationships with its customers are interrupted for any reason, the Company believes that it would be able to locate another customer to purchase its metals concentrates; however, any interruption could temporarily disrupt the Company's sale of its products and adversely affect operating results.

      2. Summary of Significant Accounting Policies (Continued)

      Use of estimates

              The preparation of financial statements in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the combined financial statements and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and various other assumptions that are believed to be reasonable given the specific circumstances. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include receivables; inventories; mineral properties; reclamation and closure obligations; valuation allowances for deferred tax assets; depreciation, depletion and accretion and the fair value of financial instruments.

      Functional currency and translation of foreign currencies

              The U.S. dollar is the LGJV's functional currency. Monetary assets and liabilities denominated in foreign currencies are translated to U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting gains or losses reported in foreign exchange (gain) loss in the computation of net loss. Non-monetary assets and liabilities are translated into U.S. dollars at historical exchange rates. Expenses and other income and expense items in foreign currencies are translated into U.S. dollars at average or historical exchange rates.

      Cash and cash equivalents

              The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

      Metal and Materials Inventories

              The Company's inventories include ore, concentrate and operating materials and supplies. The classification of ore and concentrate inventories is determined by the production stage of the ore. All inventories are stated at the lower of cost or net realizable value. Cost is determined using the average cost method for all inventories and includes applicable taxes and freight. Ore inventory represents stockpiled ore that is available for processing. Concentrate inventory represents stockpiled lead or zinc concentrate that is available for shipment or in transit to customers. Ore and concentrate inventories include applicable operating and overhead costs.

      Mine development

              The Feasibility Study established LGP's proven and probable reserves in early January 2017. Accordingly, subsequent development costs were capitalized as mine development assets until September 1, 2019 when the LGP achieved production. Subsequent to September 1, 2019, costs incurred to develop the mine are capitalized to mine development assets. Upon the commencement of production, capitalized costs are charged to operations using the units-of-production method in the period the applicable metal reserves are processed over the estimated proven and probable reserve tons directly benefiting from the capital expenditures. The LGJV incurred $7,291 and nil for the years ended December 31, 2019 and 2018, respectively, in depletion expense.

      (In thousands, except share, per share and option amounts, tonnes or as otherwise noted)

      2. Summary of Significant Accounting Policies (Continued)

              Upon abandonment or sale of a mineral property, any remaining capitalized mine development costs relating to such property will be removed from the balance sheet and a gain or loss recognized.

      Property, plant and equipment

              Property, plant and equipment are recorded at cost and depreciation is calculated on the straight-line method over the estimated useful lives of the assets. The estimated useful lives of plant and equipment and infrastructure range between three years and the end of the proven and probable reserves mine life. The estimated useful lives of furniture, fixtures and computers range from three to ten years.

      Impairment of long-lived assets

              Long-lived assets, such as property, plant and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. There were no impairments recognized for 2019 or 2018.

      Value added tax receivable and payable

              Value added taxes ("VAT") are assessed on purchases of materials, services and sales of products. The Company is entitled to recover the taxes they have paid related to purchases of materials and services. The Company collects VAT when certain products are sold to customers VAT receivables represent refundable value-added taxes paid to the Mexican government on certain transactions in Mexico. The Company records the VAT cash flows as operating activities in the combined statement of cash flows, given the short-term, refundable and operating characteristics of these cash flows.

      Reclamation and remediation costs (asset retirement obligations)

              The Company has asset retirement obligations ("ARO") arising from regulatory requirements to perform certain property and asset reclamation activities at the end of the respective asset life. An ARO is recognized when incurred and is initially measured at fair value and subsequently adjusted for accretion expense and changes in the amount or timing of the estimated cash flows. The corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and amortized over the asset's remaining useful life. The ARO is based on timing of expected spending for an existing environmental disturbance. The Company reviews, on an annual basis, unless otherwise deemed necessary, its reclamation obligation.

      2. Summary of Significant Accounting Policies (Continued)

      Revenue Recognition

              The Company generates revenue by selling silver-bearing lead and zinc concentrates. Concentrate sales are initially recorded based on 100% of the provisional sales prices, net of estimated treatment and refining charges, when it satisfies the performance obligation of transferring control of the concentrate to the customer. Concentrate revenue is initially recorded on a provisional basis based on historical prices and provisional assays. Final settlement is based on the final assays and an applicable price as determined by a future quotational period at the time of sale. Market changes in the prices of metals between the delivery and final settlement dates will result in adjustments to revenues related to previously recorded sales of concentrate.

      Income taxes

              The Company's income tax jurisdiction is Mexico. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company recognizes tax penalties in income tax expense.

      Recently issued accounting standards

      In February 2012, air monitoring2016, the FASB issued ASU 2016-02, "Leases," which will require lessees to recognize assets and liabilities for the rights and obligations created by most leases on the balance sheet. These changes become effective for the Company's fiscal year beginning January 1, 2021. The Company is still assessing the impact of the standard but does not expect there will be a material impact to the Combined Balance Sheet, Combined Statement of Income (Loss) or the Combined Statements of Cash Flows as a result of the adoption of ASU 2016-02. The Company is in the process of assessing the required disclosures of the new standard and expects to provide additional qualitative and quantitative disclosures related to its leasing arrangements upon adoption.

              In December 2019, ASU No. 2019-12 was issued to simplify and enhance accounting for income taxes. This update is effective in fiscal years, beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022, and early adoption is permitted. The Company is completing its assessment of the impact and anticipated adoption date of this guidance.

      6. Property, Plant and Equipment, net (Continued)

              The Company is required to make mineral and concession lease payments to various entities to secure its claims or surface rights. One of these agreements also requires royalty payments based on the production and sale of minerals.

      Mining Concessions and Agreement

              In Mexico, mineral concessions from the Mexican government can only be held by Mexican nationals or Mexican-incorporated companies. The concessions are valid for 50 years and are extendable provided the concessions are kept in good standing. For concessions to remain in good standing, a semi-annual fee must be paid to the Mexican government and a report must be filed each year which covers the work accomplished on the property during the previous year. These concessions may be cancelled without penalty with prior notice to the Mexican government.

              MPR is the concession holder of a series of mineral concessions granted by the Mexican government. The rights to certain concessions are held through exploration agreements with purchase options or a finder's fee agreement, as discussed below:

      La Cuesta International S.A. de C.V. (La Cuesta)

              The Company is required to make quarterly advance royalty payments and is required to pay a production royalty of a) 2% net smelter return on production from the concession until all payments reach $10,000 and b) 0.5% net smelter return on production from the concession after total payments have reached $10,000 and c) 0.5% net smelter return on production from other property within a one-kilometer boundary of the Los Gatos concession. After total payments reach $15,000, the Los Gatos concession ownership will be transferred to the Company. During the pre-production phase, the Company is obligated to complete a minimum of $100 of exploration and development work annually on the concession. The agreement has no expiration date; however, the Company may terminate the agreement upon a 30-day notice. Under this agreement, the first royalty payment is due on or before March 31, 2021, net of advance royalty payments. The Company has remitted $535 in advance royalty payments under this contract through December 31, 2019.

              As of December 31, 2019, the Company's minimum La Cuesta obligation is summarized in the table below:

      8. Related-Party Transactions

              Effective January 1, 2015, the LGJV has a management services agreement with SSMRC whereby, SSMRC provides certain consulting and administrative services. The LGJV incurred $5,100 and $3,950 for the years ended December 31, 2019 and 2018, respectively, for these services. Certain expenses incurred by the owners on behalf of the LGJV are reimbursed.

      9. Related Party Debt

              On July 11, 2017, the Company entered into a loan agreement ("Term Loan") with Dowa whereby the Company can borrow up to $210,000 for LGP development, with a maturity date of December 29, 2027. Interest on this loan accrues daily at LIBOR plus 2.35%, but the interest is added to the amount borrowed for repayment monthly until December 29, 2019. A $4,200 fee was paid to Dowa during 2018 upon the loan closing. Commencing June 30, 2021, 14 consecutive semi-annual equal payments of the aggregate principal plus accrued interest on the payment date begin. The Term Loan also requires accelerated principal payments equal to 70% of excess cash flows (as defined) from the LGP. As of December 31, 2019, the Company had $221,900 outstanding, including $11,900 of interest, under the Term Loan. In early 2019, the Company borrowed the remaining $75,000 available under the Term Loan. As of December 31, 2018, the Company had $137,300 outstanding, including $2,300 of interest, under the Term Loan. Prior to production commencing in September 2019, $7,100 of interest was capitalized to Mine Development or Property, Plant and Equipment. Subsequent to production, $3,400 of interest was expensed. During 2018, all interest was capitalized to Mine Development or Property, Plant and Equipment.

              On January 23, 2018, the Company entered into a loan agreement ("Dowa MPR Loan") whereby the Company could borrow up to $65,000 for LGP development. Interest on this loan accrues daily at LIBOR plus 1.5%. but the interest is added to the amount borrowed. All interest was capitalized to Mine Development or Property, Plant and Equipment. The amount borrowed, including accrued and unpaid interest, was due the earlier of June 30, 2019, or upon substantial completion of the LGP development. If the Dowa MPR Loan was not repaid by the maturity date, Dowa could elect to convert all or a portion of SSMRC's portion of the outstanding Dowa MPR Loan, including accrued interest, to additional equity in the LGJV Entities at 170% of SSMRC's portion of the outstanding balance ("Additional Equity"). If SSMRC's ownership in the LGJV Entities was diluted, for two years from the maturity date, SSMRC can repurchase the Additional Equity for 170% of such value plus all costs and expenses incurred by Dowa to acquire and hold the Additional Equity. In May 2019, SSMRC

      9. Related Party Debt (Continued)

      contributed $18,200 to OSJ to provide funding for a partial repayment of principal and interest related to the Dowa MPR Loan. In May 2019, the Dowa MPR Loan was fully extinguished with a principal and interest payment of $18,200 and the conversion of the remaining principal and interest of $50,737 to additional Dowa ownership in the LGJV entities. Subsequent to this transaction the ownership of the LGJV entities is 51.5% SSMRC and 48.5% Dowa.

              On May 30, 2019, the LGJV entered into a working capital facility agreement ("WCF") with Dowa whereby the LGJV could borrow up to $60,000 to fund the working capital and sustaining capital requirements of the LGP. Interest on the WCF accrues daily at LIBOR plus 3.0%. The maturity date of the WCF is June 28, 2021. As of December 31, 2019, the LGJV had $60,000 of principal and $8 of accrued interest outstanding under this facility. The Company paid interest of $1,419 under this facility for the year ended December 31, 2019.

              SSMRC incurs certain fees on behalf of the LGJV entities related to the Term Loan and WCF. Prior to production, these fees were capitalized, subsequent to production, these fees were expensed.

              Scheduled minimum debt repayments are as follows for the year ending December 31:

              During 2019, Dowa and SSMRC, contributed $50,737 and $18,200, respectively, as owners' capital to the LGJV as a result of the extinguishment of the Dowa MPR Loan. As of December 31, 2019, the ownership of the LGJV entities was 51.5% SSMRC and 48.5% Dowa. As of December 31, 2018, the ownership of the LGJV entities was 70% SSMRC and 30% Dowa.

      11. Asset Retirement Obligations

              In 2015, the Company recognized an underground fireARO related to the work performed at the 3100LGP. The Company estimated the present value of the estimated future cash flows required to revegetate the disturbed areas and perform any required monitoring. The Company used a discount rate and interest rate of 9% and 1%, respectively, to calculate the present value of this obligation, related to the disturbance of land around the mine portal, waste rock dump and road to the explosives storage area.

              In 2018, the Company recognized an ARO related to the additional development work performed at the LGP. The Company estimated the present value of the estimated future cash flows required to reclaim the disturbed areas and perform any required monitoring. The Company used a discount rate and interest rate of 7.5% and 3%, respectively, to calculate the present value.

      12. Fair Value Measurements

              The Company establishes a framework for measuring the fair value of financial assets and liabilities and nonfinancial assets and liabilities which are measured at fair value on a recurring (annual) basis in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:

              Level 1:    Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

              Level 2:    Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

              Level 3:    Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

      Financial Assets and Liabilities

              At December 31, 2019 the Company's financial instruments consist of cash and cash equivalents, receivables, restricted cash, other current assets, accounts payable and other current liabilities. The carrying amounts of these financial instruments approximate fair value due to their short maturities.

              The following table details the fair value of the Company's debt obligations as of December 31, 2019 and 2018 and are included in Level 2 of the fair value hierarchy. The Term Loan is carried at amortized cost. The fair value of the WCF approximates carrying value as the liability is secured, has a variable interest rate, and lacks credit concerns. The carrying value of the equipment loans approximate fair value as the liability is secured by the underlying equipment, guaranteed by SSMRC, and lacks

      significant credit concerns. The fair value of the Term Loan was estimated using observable inputs directly related to the obligations. The following table summarizes the fair value as of December 31:

      (1)
      Net of unamortized debt discount of $4,133 and $4,684 as of December 31, 2019 and 2018, respectively.

      Non-Financial Assets and Liabilities

              The Company discloses and recognizes its non-financial assets and liabilities, such as ARO, at fair value on a non-recurring basis. The estimated fair value for these non-financial assets and liabilities are classified as Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions that market participants would use in the pricing of such liabilities without observable inputs and no market activity.

      13. Commitments and Contingencies

              In determining accruals and disclosures with respect to loss contingencies, the Company will charge to income an estimated loss if information available prior to the issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the commitments and contingencies are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the combined financial statements when it is at least reasonably possible that a material loss could be incurred.

              The Company's mining, development and exploration activities are subject to various laws, regulations and permits governing the protection of the environment. These laws, regulations and permits are continually changing and are generally becoming more restrictive. The Company has made, and expects to make in the future, expenditures to comply with such laws, regulations and permits, but cannot predict the full amount of such future expenditures.

              From time to time, the Company may be involved in legal proceedings related to its business. Management does not believe that adverse decisions in any pending or threatened proceeding or that amounts that may be required to be paid by reason thereof will have a material adverse effect of the Company's combined financial condition or results of operations.

      14. Equipment Loans

              During 2019 and 2018, the LGJV Entities entered into equipment loan agreements, with repayment over four years at interest rates ranging from 5.76% to 8.67%, to finance a portion of

      14. Equipment Loans (Continued)

      mining equipment purchases. As of December 31, 2019, and 2018, the Company had outstanding loans of $19,915 and $18,721, respectively, and incurred $1,647 and $607 of interest, respectively. Prior to production and during 2018 all interest was capitalized to Property, Plant and Equipment. Subsequent to production in September 2019, all interest on equipment was expensed. SSMRC has guaranteed the payment of all obligations, including accrued interest, under the equipment loan agreements.

      15. Income Taxes

              The combined loss before income taxes in Mexico is $22,103 and $662 for the years ended December 31, 2019 and 2018, respectively. The combined current and deferred income tax expense for the years ended December 31, 2019 and 2018 was nil.

              A reconciliation of the actual income tax expense (benefit) and the tax computed by applying the Mexico federal rate (30%) to the loss before income taxes for the year ended December 31, is as follows:

       
       2019 2018 

      Tax benefit from continuing operations

       $(6,631)$(199)

      Nondeductible Expenses

        2,244  1,207 

      Change in Valuation Allowance

        3,773  16,052 

      NOL inflation adjustment

        41  (17,060)

      NOL expiration

        574   

      Total income tax expense (benefit)

       $ $ 

              The net operating loss (NOL) inflation rate adjustment relates to historical net operating loss carryforwards in Mexico from 2007 to 2019. These historical carryforwards have been inflation-adjusted based upon an inflation factor published by the central bank of Mexico, as any inflationary adjustment will impact the Company's basis in the net operating losses during the carryforward period.

      15. Income Taxes (Continued)

              A summary of the components of the net deferred tax assets for the year ended December 31, is as follows:

       
       2019 2018 

      Deferred tax assets

       $112 $105

        5,838  4,412

        (423) (504)

      Total deferred tax liability

        (423) (504)

      Net deferred income tax assets (liabilities)

       $ $ 

              Based upon the level of taxable income (loss) and projections of future taxable income (loss) over the periods which the deferred tax assets are deductible, management believes it is more likely than not that the Company will not realize the benefits of these deductible differences, and thus has recorded a valuation allowance against the net deferred tax asset balance of $49,567. If the Company is profitable for a number of years and prospects for the realization of the deferred tax assets are more likely than not, the Company will then reverse its valuation allowance and credit income tax expense.

              At December 31, 2019, the Company had $138,089 of net operating loss carryforwards in Mexico (including inflation adjustments) which expire at various dates through 2029. The statute of limitations for tax returns filed in Mexico is five years from the date of filing. The tax returns of the Company are no longer subject to examinations by Mexican tax authorities for years prior to 2015.

              As of December 31, 2019, the Company has not recorded any unrecognized tax benefits, as it is more likely than not that all tax positions have a high probability of being upheld by the taxing authorities. The Company recognizes penalties and accrued interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. No such interest or penalties were recognized.

      16. Subsequent Events

              On March 30, 2020, in response to the coronavirus pandemic, the Mexico government issued a temporary 30-day suspension of all non-essential activities ("Mexico Advisory"). Accordingly, the Company will temporarily suspend the non-essential LGJV activities. The Company will be able to maintain essential activities during the suspension with its existing cash, receivables and, if necessary, additional owner capital contributions.

      16. Subsequent Events (Continued)

              Due to the recent declines in the silver and zinc prices, the Company has developed an optimized mining and processing plan ("Optimized Plan") to be implemented in 2020. Should silver and zinc prices remain relatively low at the expiration of the Mexico Advisory, the Company expects to begin implementing the Optimized Plan. The Optimized Plan processes higher-grade ore, at a slightly lower throughput, to cover operating costs while metals prices remain low. The Optimized Plan provides flexibility to return to design production rates as metal prices improve.

              There are no other events or transactions requiring recognition in these combined financial statements, through April 1, 2020.

              The Company has conducted an advanced exploration drilling program and a rehabilitation program to improve certain mining infrastructure at the Sunshine Mine. The Sunshine Complex, located in the Coeur d'Alene Mining District in Idaho, is comprised of the Sunshine Mine. All mine personnel were safely evacuated,Mine and the federalSunshine Big Creek Refinery.

      Mexico—Los Gatos Project

              The Company's primary Mexico efforts are focused on the operation of the Los Gatos Joint Venture ("LGJV") in Chihuahua Mexico. On January 1, 2015, the Company entered into the LGJV to develop the Los Gatos project ("LGP") with Dowa Metals and Mining Co., Ltd. ("Dowa"). The LGJV operating entities consist of Minera Plata Real S. de R.L. de C.V ("MPR"), Operaciones San Jose del Plata S. de R.L. de C.V. ("OSJ") and Servicios San Jose del Plata S. de R.L. de C.V. (collectively the "LGJV Entities"). The LGJV completed an advanced definitional drilling and decline development program in 2016 and completed a feasibility study in January 2017. Dowa completed its $50,000 funding requirement on April 1, 2016; thereby acquiring an initial 30% interest in the LGJV and the right to purchase future zinc-concentrate production at market rates. In May 2019, Dowa increased its ownership interest to 48.5% through the conversion of the Dowa MPR Loan to equity, see Note 11 for further discussion. The LGJV ownership is currently 51.5% SSMRC and 48.5% Dowa.

              On September 1, 2019, the LGP commenced commercial production of its two concentrate products; a lead concentrate and a zinc concentrate. The LGP's lead concentrate is sold to customers within the country of Mexico while the LGP's zinc concentrate is sold to Dowa or sold to a customer within the country of Mexico.

              On March 2012, access30, 2020, in response to the upper levelscoronavirus pandemic, the Mexican government issued a temporary 30-day suspension of all non-essential activities, which was subsequently extended to May 31, 2020. Accordingly, the LGJV temporarily suspended non-essential activities. The LGJV resumed mining operations in late May 2020 as permitted by the Mexican Government.

              The Company's financial statements have been presented on the basis that it is a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has a history of operating losses and cash outflows from operations, which are expected to continue through at least 2021. Management evaluates whether conditions or events raise substantial doubt about the Company's ability to continue as a going concern within one year after the date the consolidated interim financial statements are issued. In performing this assessment,

      management considered the risks associated with its ongoing ability to fund the Company's existing operations, specifically its holding costs at the Sunshine Complex, general and administrative expenses, and the Company's obligations related to the LGJV, which includes $45 million in capital contributions to the LJGV in June 2021. The Company has received a financial support commitment for $18,000 from Electrum its primary shareholder, which matures on June 25, 2021. Based on the Company's current cash flow forecasts, there is an expected cash shortfall within one year of the mine was reestablished in April 2012, and access to the lower levelsissuance date of the mine was reestablished in June 2012.

              In April 2020, the Company received $567 under a forgivable loan, bearing 1% annual interest, related to the remediationPaycheck Protection Program ("PPP"). The PPP, established as part of the United States' Coronavirus Aid, Relief and Economic Security Act ("CARES Act"), provides loans to qualifying businesses for amounts up to 2.5 times the average monthly payroll expenses of the qualifying business. The loans and accrued interest are forgivable as long as the borrower uses the loan proceeds for eligible purposes, including payroll, benefits, rent and utilities, and maintains its payroll levels.

              The Company believes it used the loan proceeds for purposes consistent with the PPP. While the Company currently believes that its use of the loan proceeds has met the conditions for forgiveness of the loan, the Company cannot guarantee forgiveness of the loan, in whole or in part. Should the loan not be forgiven, the Company intends to repay the loan within one year.

      6. Related-Party Convertible Notes

              The Company entered into convertible promissory note agreements with Electrum Silver US LLC, during the second quarter of 2020, to borrow up to $15,000. The convertible promissory notes bear a 5% annual interest rate. Upon the Company issuing common stock in a qualified financing, as defined, prior to April 19, 2023, the principal amount then outstanding and accrued but unpaid interest under the promissory notes will automatically convert into common stock of the Company at a price per share equal to the lesser of (A) 80% of the price per share of the shares that are issued and sold by the Company in the qualified financing or (B) $7.50 per share. The convertible promissory notes and any accrued but unpaid interest is due and payable on April 19, 2023, unless converted, exchanged or otherwise paid.

At June 30, 2020 and December 31, 2019, the Company had restricted cash in the form of a certificate of deposit totaling $275 as collateral for a letter of credit issued by a financial institution as security to a governmental agency for certain of the Company's reclamation obligations.

      10. Fair Value Measurements

              The Company establishes a framework for measuring the fair value of financial assets and liabilities and nonfinancial assets and liabilities, which are measured at fair value on a recurring (annual) basis in the form of a fair value hierarchy that prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs. Financial assets and liabilities are classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy are as follows:

              Level 1:    Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.

              Level 2:    Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

      (In thousands, except share, per share, option, and stock unit amounts)

      10. Fair Value Measurements (Continued)

              Level 3:    Unobservable inputs due to the fact there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

      Financial Assets and Liabilities

              At June 30, 2020 and December 31, 2019, the Company's financial instruments consist of cash and cash equivalents, restricted cash, receivables, accounts payable and other current liabilities. The carrying amounts of these financial instruments approximate fair value due to their short maturities.

      Non-Financial Assets and Liabilities

              The Company discloses and recognizes its non-financial assets and liabilities, such as ARO, at fair value on a non-recurring basis. The estimated fair value for these non-financial liabilities are classified as Level 3 of the fair value hierarchy, as the valuation are determined based on internally developed assumptions that market participants would use in the pricing of such assets without observable inputs and no market activity.

              The Company recorded its initial investment in affiliates at fair value. The estimated fair value for this non-financial asset is classified as Level 3 of the fair value hierarchy, as the valuation was determined based on internally developed assumptions with few observable inputs and no market activity.

      11. Commitments, Contingencies and Guarantees

              In determining its accruals and disclosures with respect to loss contingencies, the Company will charge to income an estimated loss if information available prior to the issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Legal expenses associated with the commitments and contingencies are expensed as incurred. If a loss contingency is not probable or reasonably estimable, disclosure of the loss contingency is made in the financial statements when it is at least reasonably possible that a material loss could be incurred.

              The Company's mining and exploration activities are subject to various laws, regulations and permits governing the protection of the environment. These laws, regulations and permits are continually changing and are generally becoming more restrictive. The Company has made, and expects to make in the future, expenditures to comply with such laws, regulations and permits, but cannot predict the full amount of such future expenditures.

              In July 2017, the LGJV Entities entered into a loan agreement (the "Term Loan") with Dowa whereby the LGJV Entities could borrow up to $210,000 for LGP development, with a maturity date of December 29, 2027. Interest on the Term Loan accrues daily at LIBOR plus 2.35%, with the interest to be added to the amount borrowed until commencement of production. During 2018, the LGJV paid Dowa a $4,200 closing fee. Commencing June 30, 2021, 14 consecutive semi-annual equal payments of the aggregate principal and capitalized interest begin. The Company is required to pay an arrangement fee on the borrowing, calculated as 70%, of 1% of the outstanding principal balance, two business days prior to June 30 and December 31 each fiscal year until maturity, commencing after the initial

      drawdown which occurred in July 2018. The Term Loan also requires additional principal payments equal to 70% of excess cash flows (as defined). As of June 30, 2020, the LGJV had $222,783 outstanding under the Term Loan.

              On January 23, 2018, the LGJV entered into a loan agreement (the "Dowa MPR Loan") with Dowa whereby the LGJV could borrow up to $65,700 to continue LGP development. Interest on this loan accrued daily at LIBOR plus 1.5% and was added to the amount borrowed. The amount borrowed plus accrued interest was due the earlier of June 30, 2019, or upon LGP's substantial completion. If the Company's 70% portion of the Dowa MPR Loan was not repaid in full on or before the due date, Dowa could elect to convert all or a portion of the principal amount into additional LGJV ownership at a favorable conversion rate.

              The Company contributed $18,200 to the LGJV in May 2019 to provide funding for a partial repayment of principal and interest related to the Dowa MPR Loan. In late May 2019, the Dowa MPR Loan was fully extinguished with a cash payment of $18,200 and the conversion of the remaining $50,737 of principal and interest. The conversion of the remaining principal and interest increased Dowa's ownership in the LGJV entities to 48.5%. At June 30, 2020, the ownership of the LGJV entities is 51.5% SSMRC and 48.5% Dowa. Due to the LGJV ownership dilution, the Company recognized a dilution loss on affiliates of $11,231 in May 2019. SSMRC has until June 30, 2021 to repurchase the 18.5% interest for SSMRC's unpaid portion of the Dowa MPR loan amount, plus a 70% penalty and any Dowa holding costs of this incremental interest.

              On May 30, 2019, the LGJV entered into a working capital facility agreement (the "WCF") with Dowa whereby the LGJV could borrow up to $60,000 to fund the working capital and sustaining capital requirements of the LGP. Interest on this loan accrues daily at LIBOR plus 3.0% and all outstanding principal and interest matures on June 28, 2021. The Company is required to pay an arrangement fee on the borrowing, calculated as 15.0% per annum of 70.0% of the average daily principal amount outstanding under the WCF during such fiscal quarter. As of June 30, 2020, the LGJV had $60,000 outstanding under the WCF.

              The Company has guaranteed 70% of the outstanding principal and accrued interest of the Term Loan and the WCF in the event of default by the LGJV. The Company has guaranteed the payment of all obligations, including accrued interest, under the LGJV equipment loan agreements

      12. Segment Information

      Item 14.Indemnification of Directors and Officers.

      Section 145 of the Delaware General Corporation Law, or the DGCL, provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys’attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending or completed actions, suits or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee or agent to such corporation. The DGCL provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise. The Registrant’sRegistrant's Amended and Restated Certificate of Incorporation provides for indemnification by the Registrant of its directors, officers and employees to the fullest extent permitted by the DGCL. The Registrant intends to enter into indemnification agreements with each of its directors and executive officers to provide these directors and officers additional contractual assurances regarding the scope of the indemnification set forth in the Registrant's Amended and Restated Certificate of Incorporation and to provide additional procedural protections. These agreements, among other things, will require the Registrant to indemnify each director and executive officer to the fullest extent permitted by Delaware law, including indemnification for expenses such as attorneys' fees, judgments, fines and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in right of the Registrant, arising out of the person's services as a director or executive officer.

      Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’sdirector's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payments of dividends or unlawful stock repurchases, redemptions or other distributions, or (iv) for any

      transaction from which the director derived an improper personal benefit. The Registrant’sRegistrant's Amended and Restated Certificate of Incorporation provides for such limitation of liability.

      The Registrant intends to enter into indemnification agreements with each of its directors and executive officers. These agreements, among other things, will require the Registrant to indemnify each director and executive officer to the fullest extent permitted by Delaware law, including indemnification for expenses such as attorneys’ fees, judgments, fines and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in right of the Registrant, arising out of the person’s services as a director or executive officer.

      The Registrant maintains standard policies of insurance under which coverage is provided (a) to its directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act, and (b) to the Registrant with respect to payments which may be made by the Registrant to such officers and directors pursuant to the above indemnification provision or otherwise as a matter of law.

      Item 17.UndertakingsUndertakings.

              The undersigned Registrant hereby undertakes:

                (a)   Insofar as indemnification for liabilities arising under the U.S. Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions referenced in Item 14 of this Registration Statement, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the U.S. Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the U.S. Securities Act and will be governed by the final adjudication of such issue.

      The undersigned Registrant hereby undertakes:undertakes that:
