Mr. Harris has over 20 years of experience in managing mining operations in Latin America that include base metal and gold deposits, underground and open pit mines, gold and base metal processing plants and smelting and refining operations.  In evaluating Mr. Harris’s qualifications to serve as a director, the Board believes Mr. Harris experience in managing and developing mines all over the world, but specifically in Peru and Latin America, where much of Solitario’s exploration efforts have been focused, is paramount to the success of Solitario.  In addition, Mr. Harris has a strong reputation in the mining industry and has provided Solitario with numerous opportunities and introductions that Solitario would likely not have had without his association with Solitario as a Board member.  Mr. Harris currently serves on the board of directors of Aztec Metals Corp., Canarc Resources, Wealth Minerals, Inc and Cardero Resources Corp.  He is a 1949 graduate metallurgist of The Mount Morgan School of Mines (Australia).

Item 11.Executive Compensation

Compensation Discussion and Analysis

The following discussion provides information regarding the compensation program for Solitario's Named Executive Officers for 2016.

Objectives of the Company’s Compensation Program

The Compensation and Management Development Committee (the “Compensation Committee”) has responsibility for approving the compensation program for Solitario's Named Executive Officers and acts according to a charter that has been approved by the Board and is available on the Company website at www.solitarioxr.com. The compensation program is designed to attract, retain and reward our executives who contribute to Solitario's long-term success. This in turn is intended to build value for Solitario and its shareholders. The program is based upon three fundamental principles:

(1)       A substantial portion of Solitario's Named Executive Officer compensation should be performance and equity-based to achieve alignment with shareholder interests.

This principle is accomplished in two primary ways; first, through the award of stock options or, other equity awards contemplated in the equity compensation plans adopted by Solitario, in an amount and with such terms intended to encourage our Named Executive Officers to promote the long-term growth and performance of Solitario as may be reflected in the price of our Common Stock as quoted on the TSX and the NYSE-MKT.

Second, this is also reflected in terms of cash compensation in the form of cash bonuses. These bonuses are set by the Compensation Committee, in its sole discretion, in a range of zero to 100% of base salary. The extent to which bonuses are paid depends entirely on the extent to which the Compensation Committee believes Solitario has met its development, exploration, budget and shareholder goals, as set by the Compensation Committee and the current and expected financial condition of the Company. In March 2016 the Compensation Committee awarded a $60,000 bonus to Mr. Herald, a $44,000 bonus to Mr. Hunt and a $40,000 bonus to Mr. Maronick for the performance of the Named Executive Officers and the achievement of certain Company goals during 2015. The Compensation Committee considered the milestones achieved during 2015 by the Company, including (i) completion of the sale of our former interest in the Mt. Hamilton project through the sale of our interest in Mt. Hamilton LLC (“MH-LLC”) to Waterton Nevada Splitter, Ltd. (“Waterton”) for gross proceeds of $24,000,000 (the “Transaction”), (ii) the refinancing and eventual repayment, upon the closing of the Transaction, of $5,000,000 short-term debt due to RMB Australia Holdings, Ltd., and (iii) successful marketing of our interest in MH-LLC, including obtaining approval of the Transaction by holders of over 90% of our outstanding shares at our annual meeting held in August 2015. Primarily due to the limited financial resources of the Company during 2015, prior to the sale of our interest in MH-LLC, no bonuses were authorized by the Compensation Committee to be paid during 2015. The Compensation Committee considered the bonuses paid in 2016 as earned in 2015 and these bonuses are included in the summary compensation table below for each Named Executive Officer for the year ended December 31, 2015. The Compensation Committee did not award any bonuses for the year ended December 31, 2016 to any Named Executive Officer based upon their review of the performance of the price of the Company’s common stock during the year and upon the absence of a major mineral property acquisition and / or strategic investment during the year ended December 31, 2016.

(2)        Solitario's compensation program for Named Executive Officers is intended to enable the Company to compete for the best executive talent available.

The Compensation Committee believes shareholders are best served when the Company can attract and retain the highest caliber executives appropriate for a company of our size and complexity. This is done with compensation packages we believe to be fair and competitive. Our Named Executive Officers have served Solitario for many years. During 2016 and 2015 the Compensation Committee reviewed published compensation surveys and publically available compensation disclosures of several of our peer group companies (“Peer Group Companies”) for which Solitario competes for executive talent as the Compensation Committee believes that each of these public companies share some attributes of Solitario with regard to similar size to, and in a similar industry as Solitario. These Peer Group Companies included the following companies:

Vista Gold Corp.Midas Gold Corp.
Entree Gold Corp.Riverside Resources Inc.

These reviews were not used to create specific benchmarks applicable to our Named Executive Officer compensation levels. These reviews were used to inform the Compensation Committee of current standards in the industry as such standards may relate, in their independent judgment, to appropriate modifications to Solitario's existing compensation levels. During 2016, Solitario's activities were generally focused on the evaluation of mineral properties for acquisition, Solitario also evaluates potential strategic transactions as a means to acquire and on junior mining companiesinterest in new precious and base metal properties and assets with exploration potential or other potential corporate transactions that Solitario determines to be favorable to Solitario.

Solitario has recorded revenue from the sale of mineral properties for strategic investmentand assets, including the sale of certain mineral royalties in January of 2019 and the sale in April of 2018 of its interest in the formroyalty on the Yanacocha property, discussed below. Revenues from the sale or joint venture of potential merger, acquisitionproperties or sale;assets, although significant when they occur, have not been a consistent annual source of revenue and would only occur in the future, if at all, on an infrequent basis.
Solitario currently considers its carried interest in the Florida Canyon project in Peru and its interest in the Lik project in Alaska to be its core mineral property assets. Nexa Resources, Ltd. (“Nexa”), Solitario’s joint venture partner, completed a 39-hole 17,033-meter drilling program at Florida Canyon during most2019 (discussed below). Solitario is working with its 50% joint venture partner, Teck American Inc., a wholly-owned subsidiary of 2015 Solitario’s activities were more narrowly focused initially onTeck Resources Limited (both companies are referred to in this Annual Report as “Teck”) and completed a limited exploration program at the Lik project during 2019 consisting of mapping, geophysical work, relogging of prior drilling core and environmental evaluation.
As of December 31, 2019, Solitario has significant balances of cash and short-term investments that Solitario anticipates using, in part, to further the development of the Mt. Hamilton project,Florida Canyon and subsequently on the marketingLik projects and eventual sale of the Mt. Hamilton project,to potentially acquire additional mineral property assets. The fluctuations in precious metal and other commodity prices contribute to a challenging environment for mineral exploration and development, which has created opportunities as well as challenges for the potential acquisition of early-stage and advanced mineral exploration projects or other early stage exploration. Asrelated assets at potentially attractive terms.
Recent Developments
On January 22, 2019, Solitario completed the focussale of its interest in certain royalties to SilverStream SEZC, a private Cayman Island royalty and streaming company (“SilverStream”), for Cdn$600,000 (the “Royalty Sale”). The Royalty Sale covered (i) a royalty on the formerly Solitario-owned 125,000-acre polymetallic Pedra Branca palladium, platinum, gold, nickel, cobalt and chrome project in Brazil, (ii) a royalty covering 3,880 acres of non-producing exploration properties in Mexico, and (iii) a purchase option on royalties covering 11 separate non-producing properties covering over 16,500 acres in Montana. At closing of the Royalty Sale, Solitario received Cdn$250,000 in cash and a convertible note from SilverStream in the principal amount of Cdn$350,000 (the “SilverStream Note”). The SilverStream Note was originally due December 31, 2019, accrued 5% per annum simple interest, payable on a quarterly basis, and is convertible into common shares of SilverStream, at the discretion of SilverStream, by providing Solitario a notice of conversion. In December of 2019, Solitario and SilverStream agreed to extend the due date of the SilverStream Note to June 30, 2020, and to increase the interest rate to 8% per annum simple interest. All other terms of the SilverStream Note remained the same. SilverStream may only provide a notice of conversion if SilverStream has completed an initial public offering during the term of the SilverStream Note for minimum proceeds of Cdn$5,000,000, otherwise the SilverStream Note will be payable in cash at the maturity date. Pursuant to the terms of the SilverStream Note, if SilverStream were to complete an initial public offering and the SilverStream Note was converted, Solitario would receive common shares converted at 85% of the weighted average quoted price of a share of SilverStream common stock for the most recent 10-day period prior to the notice of conversion

On April 26, 2018 Solitario sold its royalty interest in the non-producing Yanacocha property (the “Yanacocha Royalty”) to a wholly owned subsidiary of Newmont Mining Corporation (“Newmont”) for approximately $502,000 in cash. The Yanacocha Royalty covered 43 concessions totaling 36,052 hectares. Newmont owns the underlying mineral concessions covered by the Yanacocha Royalty. None of the concessions covered by the Yanacocha Royalty have any reported reserves or resources. Solitario had no mineral property capitalized cost in the Yanacocha Royalty and recorded Mineral Property Revenue of $502,000 during 2018.

Mineral Exploration Properties
We hold a 50% operating interest in the Lik zinc-lead-silver property in Northwest Alaska, which is estimated to contain a large tonnage, high-grade deposit potentially mineable by open-pit methods. Teck is a 50% partner with Solitario in the Lik deposit, with Teck acting as the project manager for 2018 and 2019. A Preliminary Economic Assessment (“PEA”) was completed on the Lik deposit in 2014.
Solitario also has a 39% interest in the advanced, high-grade, Florida Canyon zinc project located in northern Peru. The project has a significant mineral resource and Solitario is fully carried to production by its joint venture partner Nexa, formerly Votorantim Metais Holdings, SA (“Votorantim”) and Compañía Minera Milpo S.A.A. (“Milpo”). Solitario and Nexa completed a PEA on the Florida Canyon deposit in August 2017. Nexa is one of the largest zinc producers in Peru. Except for the 2018-2019 drilling program, discussed below, Nexa has funded 100% of project expenditures since the inception of the Florida Canyon joint venture in 2006. Nexa will earn a 70% interest in the project by continuing to solely fund all project expenditures and committing to place the project into production based upon a positive feasibility study. After earning 70%, and at the request of Solitario, duringNexa has further agreed to finance Solitario's 30% participating interest for construction. Solitario will repay the two most recent fiscal years did not directly compare in all casesloan facility through 50% of its net cash flow distributions from the project.
In August of 2018, Solitario agreed to fund a portion of a 2018 – 2019 drilling program at the activitiesFlorida Canyon project. Solitario funded $1,580,000 of the Peer Group Companies, the Compensation Committee took the difference in focus into consideration when reviewing compensation of Solitario’s Named Executive Officers compared to the peer companies. Additionally, Solitario has traditionally maintained a very minimal staff and the difference in the number of total employees of Solitario,39-hole 17,033-meter drilling program, which currently has six employees world-wide, compared to the Peer Group Companies; do not lend itself to effective use of specific benchmarks.

Subsequent to the completion of the Transaction, the Compensation Committee, in consultation with the Named Executive Officers, in light of the then difficult financial conditions in the junior mining sector as a result of continued low precious and base metal prices as well as the reduction in Mt. Hamilton related Company activities, decided to reduce the annual salaries of its Named Executive Officers, as of October 1, 2015; with the salary of Mr. Herald being reduced from $230,000 to $198,000, the salary of Mr. Maronick being reduced from $160,000 to $150,000 and the salary of Mr. Hunt being reduced from $178,000 to $158,000. The Named Executive Officers’ salaries remained at the reduced amount during 2016, except for an increase in September 2016 to Mr. Hunt’s salary of $1,000 per month and an increase to Mr. Herald’s salary in June of $500 per month related to an increase in health care costs. At the beginning of 2015, based upon the difficult financial markets and the limited financial resources of the Company, the Compensation Committee decided to leave the ending annual 2014 salary amounts the same during 2015 with the salary of Mr. Herald at $230,000, the salary of Mr. Maronick at $164,000 and the salary of Mr. Hunt at $178,000. However, to conserve cash resources during 2015, all employees of Solitario, including its Named Executive Officers agreed to defer between 15% and 34% of the gross cash salary payments due during 2015. Upon completion of the Transaction, and given the strong financial condition of Solitario, all amounts previously deferred during 2015, were paidwas completed in the fourth quarter of 2015.

(3)        Solitario's compensation program2019 (the “Drilling Program”). The funding of the Drilling Program will be treated as an advance on Solitario’s commitment to fund 30% of any future construction and development costs of Florida Canyon under the original joint venture agreement discussed above. Accordingly, in the event the Florida Canyon project is developed, which cannot be assured at this time, the funds paid to Nexa under this agreement will reduce the amount of Solitario’s obligation to fund 30% of future development costs, and / or repay loans from Nexa for future development costs at the Florida Canyon project. As of December 31, 2019, Solitario has paid Nexa its entire funding commitment of $1,580,000, of which $1,053,000 and $527,000, respectively, were charged to exploration during 2019 and 2018.

At December 31, 2019, Solitario also owns the La Promesa gold exploration project. Solitario also holds an 85% interest in the Chambara exploration project in Peru (Nexa holds the remaining 15%), and a 9.8% equity interest in Vendetta Mining Corp. (“Vendetta”).
We conduct exploration and property evaluation activities in Peru either on our own using contract geologists, or through joint ventures operated by our partners.
Our exploration activities and those of our joint venture partners are carried out on a property-by-property basis. These activities may include prospecting, geologic mapping, sampling, geophysics and drilling. When we determine that this work indicates a project may not be economic or contain sufficient geologic or economic potential, we may impair or completely write-off the property. A significant factor in the success or failure of our activities is the price of commodities. For example, when the price of zinc or other commodities is down, we may determine that the value of our mineral exploration properties decreases; however, during such down markets it may also become easier and less expensive to locate and acquire new mineral exploration properties.

We have recorded revenue in the past from the sale of mineral properties and assets, joint venture property payments and the sale of a royalty on our formerly held Mt. Hamilton property. Proceeds from the sale or joint venture of properties and royalty sales, although potentially significant when they occur, have not been a consistent source of cash and may only occur in the future, if at all, on an infrequent basis. Accordingly, while we conduct exploration activities on our projects, we need to maintain and replenish our capital resources. Historically, we have met our need for capital through (i) the sale of mineral property royalties to SilverStream for $408,000 during 2019, (ii) the sale of our Yanacocha royalty to Newmont for $502,000 during 2018; (iii) proceeds received from the sale of our former Mt. Hamilton project in 2015; (iv) sales of our shares of common stock of Vendetta and Kinross Gold Corporation (“Kinross”); (v) borrowing in the form of short-term margin debt secured by our investment in Kinross; (vi) borrowing under long-term debt secured by our former Mt. Hamilton project (vii) joint venture delay rental payments, including payments on our Florida Canyon project; (viii) a royalty sale for $10,000,000 in 2012; (ix) issuances of common stock; (x) sales of covered call options on our Kinross common stock; and (xi) interest on short term Treasury Notes and Bank CDs. We have reduced our exposure to the costs of our exploration activities through the use of joint ventures.
We operate in one segment: mineral exploration. We currently conduct exploration activities in Peru and Alaska and evaluate properties for potential acquisition and evaluation of strategic corporate opportunities throughout North and South America. As of February 28, 2020, we had three full-time employees located in the United States and no full-time employees outside of the United States. We utilize contract managers, geologists, administrators and laborers to execute our Latin American and North American project work and acquisition evaluations.
A large number of companies are engaged in the acquisition, exploration and development of mineral properties, many of which have substantially greater technical and financial resources than we have and, accordingly, we may be at a disadvantage in being able to compete effectively for the Named Executive Officersacquisition, exploration and development of mineral properties. We are not aware of any single competitor or group of competitors that dominate the exploration and development of mineral properties. In acquiring mineral properties for exploration and development, we rely on the experience, technical expertise and knowledge of our employees, contractors and advisors, which is limited by the size of our company compared to many of our competitors who may have greater resources, including more employees or employees with more specialized knowledge and experience.
Governmental Regulations
Mineral development and exploration activities are subject to various national, state/provincial, and local laws and regulations, which govern prospecting, development, mining, production, exports, taxes, labor standards, occupational health, waste disposal, protection of the environment, mine safety, hazardous substances and other matters.  Similarly, if any of our properties are developed and/or mined those activities are also subject to significant governmental regulation and oversight. We are required to obtain licenses, permits and other authorizations in order to conduct our exploration programs.
Environmental Regulations
Our current and planned activities are subject to various national and local laws and regulations governing protection of the environment. These laws are continually changing and, in general, are becoming more restrictive. We are required to conduct our operations in compliance with applicable laws and regulations. Changes to current local, state or federal laws and regulations in each jurisdiction in which we conduct our exploration activities could, in the future, require additional capital expenditures and increased operating and/or reclamation costs. Although we are unable to predict what additional legislation, if any, might be proposed or enacted, additional regulatory requirements could impact the economics of our projects. During 2019, we had no material environmental incidents or non-compliance with any applicable environmental regulations.
Financial Information about Geographic Areas
Included in the consolidated balance sheets at December 31, 2019 and 2018, are total assets of $59,000 and $416,000, respectively, related to Solitario's operations located outside of the United States.
Available Information
We file our Annual Report on Form 10-K, our quarterly reports on Form 10-Q, current reports on Form 8-K, and any amendments to those reports electronically with the SEC. The SEC maintains a website (http://www.sec.gov) that contains periodic reports, proxy and information statements and other information regarding registrants, including the Company, that file electronically with the SEC.
Paper copies of our Annual Report to Shareholders, our Annual Report on Form 10-K, our quarterly reports on Form 10-Q, current reports on Form 8-K, and any amendments to those reports are available free of charge by writing to Solitario at its address on the front of this Form 10-K. In addition, electronic versions of the reports we file with the SEC are available on our website, www.solitarioxr.com as soon as practicable, after filing with the SEC.

Item 1A. Risk Factors
In addition to considering the other information in this Form 10-K, you should consider carefully the following factors. The risks described below are the significant risks we face and include all material risks of which we are aware. Additional risks not presently known to us or risks that we currently consider immaterial may also adversely affect our business.
Our mineral exploration activities involve a high degree of risk, and a significant portion of our business model envisions the sale or joint venture of mineral properties. If we are unable to sell or joint venture these properties, the money spent on acquisition and exploration of our mineral properties may never be fairrecovered and we could incur an impairment of our investments in our projects.
The exploration for mineral deposits involves significant financial and other risks over an extended period of time. Few properties that are explored are ultimately developed into producing mines. Major expenditures are required to determine if any of our mineral properties may have the potential to be commercially viable, be salable or joint ventured. Prior to completion of the feasibility study on our former Mt. Hamilton project, we had never established reserves on any of our properties. Significant additional expense and risks, including drilling and determining the feasibility of a project, are required prior to the executive,establishment of reserves. It is impossible to ensure that the Companycurrent or proposed exploration programs on properties in which we have an interest will be commercially viable or that we will be able to sell, joint venture or develop our properties. Whether a mineral deposit will be commercially viable depends on a number of factors, some of which are the particular attributes of the deposit, such as its size and all its employeesgrade, costs and perceived asefficiency of the recovery methods that can be employed, proximity to infrastructure, commodity prices, financing costs and governmental regulations, including regulations relating to prices, taxes, royalties, infrastructure, land use, importing and exporting of mineral products and environmental protection.
We believe the data obtained from our own exploration activities or our partners' activities to be reliable; however, the nature of exploration of mineral properties and analysis of geological information is often subjective, and data and conclusions are subject to uncertainty. Even if exploration activities determine that a project is commercially viable, it is impossible to ensure that such both internallydetermination will result in a profitable sale of the project or development either on our own or by a joint venture in the future and externally.

The Compensation Committee strivesthat such project will result in profitable commercial mining operations. If we determine that capitalized costs associated with any of our mineral interests are not likely to create a compensation program that promotes good corporate practice, encouragesbe recovered, we would incur an impairment of our Named Executive Officers to perform at a high level and promotes teamwork among our employees. The Compensation Committee takesinvestment in such property interest. All of these goals into consideration by comparison of executive payfactors may result in losses in relation to all other Solitario salaryamounts spent, which are not recoverable. We have experienced losses of this type from time to time in the past and may record mineral property impairments in the future.

We have no reported proven and probable mineral reserves, and our current projects and any projects we may acquire are not likely to offer the opportunity for near term revenues or sale proceeds. If we are unsuccessful in identifying mineral reserves in the future, we may not be able to realize any profit from our property interests.
None of our current projects have reported proven and probable mineral reserves as those terms are used in SEC Guide 7. Any mineral reserves on these projects will only come from extensive additional exploration, engineering and evaluation of existing or future mineral properties. The lack of reserves on these mineral properties could prohibit us from any near-term sale or joint venture of our mineral properties and we would not be able to realize any proceeds and or profit from our interests in such mineral properties, which could materially adversely affect our financial position or results of operations.
Mineral exploration activities are inherently dangerous and could cause us to incur significant unexpected costs, including legal liability for internal consistency,loss of life, damage to property and by comparisonenvironmental damage, any of which could materially adversely affect our financial position or results of operations.
Mining exploration operations are subject to both Peer Group Companiesthe hazards and industry salariesrisks normally related to exploration of a mineral deposit, including, but not limited to mapping and sampling, drilling, road building, trenching, assaying and analyzing rock samples, transportation over primitive roads or via small contract aircraft or helicopters and severe weather conditions. Any of the hazards of mining exploration could result in damage to life or property, environmental damage and possible legal liability for external consistency. In addition,such damage. Any of these risks could cause us to incur significant unexpected costs that could have a material adverse effect on our financial condition and ability to finance our exploration and development activities.
We have a history of losses and if we do not operate profitably in the compensation program is intended to enhance shareholder valuefuture it could have a material adverse effect on our financial position or results of operations and the Compensation Committee strivestrading price of our common stock would likely decline.
We have reported losses in 23 of our 26 years of operations. We can provide no assurance that we will be able to provide transparencyoperate profitably in the future or begin to generate significant and full disclosureconsistent sources of revenues or cash flows from operations. We have had net income in only three years in our history; during 2015, as a result of the sale of our former Mt. Hamilton project, during 2003, as a result of a $5,438,000 gain on a derivative instrument related to our investment in certain Crown warrants and during 2000, when we sold our former Yanacocha property. We cannot predict when, if ever, we will be profitable again or able to begin generating consistent revenues or cash flows from our operations or assets. If we do not operate profitably or identify and execute on outside sources of funding, we may be unable to fund our current or contemplated exploration activities, acquire new assets, or otherwise further our business plan.
Our operations outside of the United States of America may be adversely affected by factors outside of our control, such as changing political, local and economic conditions, any of which could materially adversely affect our financial position or results of operations.
Our mineral properties located in Latin America consist primarily of mineral concessions granted by national governmental agencies and are held 100% by us or in conjunction with our joint venture partners, or under lease, option or purchase agreements. Certain of our mineral properties are located in Peru and we have previously held royalties on non-producing exploration properties in Mexico, Brazil and Montana (U.S.) through January 22, 2019 when they were sold. We have acted as operator on all interested parties.

8
of our mineral properties or assets that are not held in joint ventures or are royalty interests. The success of projects held under joint ventures or royalty interests that are not operated by us are substantially dependent on the joint venture partner, over which we have limited or no control.

The Compensation Committee has no authority


Our current exploration activities, mineral properties and royalties located outside of the United States are subject to recover salary, bonusesthe laws of Peru and any other countries in which we may conduct business. Exploration and potential development activities in other countries we may conduct exploration are potentially subject to political and economic risks, including:
cancellation or stock option awardsrenegotiation of contracts;

disadvantages of competing against companies from countries that are not subject to US laws and regulations, including the U.S. Foreign Corrupt Practices Act (“FCPA”);
changes in foreign laws or regulations;
changes in tax laws;
royalty and tax increases or claims by governmental entities, including retroactive claims;
expropriation or nationalization of property;
currency fluctuations (particularly related to a change in the U.S. dollar compared to local currencies);
foreign exchange controls;
restrictions on the ability for us to hold U.S. dollars or other equity awards madeforeign currencies in offshore bank accounts;
import and export regulations;
environmental controls;
risks of loss due to Named Executive Officers. Althoughcommunity opposition to our activities, civil strife, acts of war, guerrilla activities, insurrection and terrorism; and
other risks arising out of foreign sovereignty over the Compensation Committee hasareas in which our exploration activities are conducted.

Accordingly, our current exploration activities outside of the ability to consider prior compensation (e.g. gainsUnited States may be substantially affected by factors beyond our control, any of which could materially adversely affect the value of certain of our assets or results of operations. Furthermore, in the event of a dispute arising from prior option grants or other equity awards) in setting current compensation, it has no formal procedure or requirement to do so. The Compensation Committee does not set or utilize benchmarks of any kind to set, evaluate or allocate compensation. There have been no actions taken or adjustments madesuch activities, we would likely be subject to the processexclusive jurisdiction of setting executive compensation discussed herein by the Compensation Committee subsequent to December 31, 2016.

Key Elements of Executive Compensation

The elementscourts outside of the Company’s compensation program are intended to balance long term and short term compensation for its executives and attempt to motivate executives to provide excellent leadership and achieve Company goals by linking short-term (such as salaries and benefits) and long-term incentives (such as equity based compensation)United States or may not be successful in subjecting persons to the achievement of business objectives, thereby aligning the interests of executives and shareholders. In addition the Compensation Committee recognizes the performancejurisdictions of the Company’s Common Stockcourts in the United States, which could adversely affect the outcome of a dispute.

We may not have sufficient funding for exploration and development, which may impair our results of operations and growth potential.
The capital required for exploration and development of mineral properties is often influenced bysubstantial. In the general investment climatepast we have financed operations through the sale of interests in mineral properties, including the juniorsale of our former Mt. Hamilton project in 2015, the utilization of joint venture arrangements with third parties (generally providing that the third party will obtain a specified percentage of our interest in a certain property or a subsidiary owning a property in exchange for the expenditure of a specified amount), the sale of other assets, the sale of marketable equity securities we hold, funds from the issuance of long-term debt, and the issuance of common stock. We may need to raise additional capital, or enter into new joint venture arrangements, in order to fund our obligations with respect to our properties and our exploration activities required to determine whether mineral deposits on our projects are commercially viable. New financing or acceptable joint venture partners may or may not be available on a basis that is acceptable to us. The inability to obtain new financing or joint venture partners on acceptable terms may prohibit us from continued development or exploration of our mineral properties. Without the successful sale or future development of our mineral properties through joint ventures, or on our own, we will not be able to realize any profit from our interests in such properties, which could have a material adverse effect on our financial position and results of operations.
A large number of companies are engaged in the exploration and development or sale of mineral properties, many of which have substantially greater technical and financial resources than us and, accordingly, we may be unable to compete effectively in this sector of the mining industry which could have a material adverse effect on our financial position or results of operations.
We are at a disadvantage with respect to many of our competitors in the acquisition, exploration and development or sale of mining projects. Our competitors with greater financial resources than us are better able to withstand the uncertainties and fluctuations associated with sustained downturns in the market and to acquire high quality exploration and mining properties when market conditions are favorable. In addition, we compete with other companies in the mineral properties sector to attract and retain key executives and other personnel with technical skills and experience in the mineral exploration business. There can be no assurance that we will continue to retain skilled and experienced employees or to acquire additional exploration projects. The realization of any of these risks from competitors could have a material adverse effect on our financial position or results of operations.

The title to our mineral properties may be defective or challenged which could have a material adverse effect on our financial position or results of operations.
In connection with the acquisition of our mineral properties, we conduct limited reviews of title and related matters, and obtain certain representations regarding ownership. These limited reviews and representations do not necessarily preclude third parties from challenging our title and, furthermore, our title may be defective. Consequently, there can be no assurance that we hold good and marketable title to all of our mineral interests. Additionally, we have to make annual filings to various government agencies on all of our mineral properties. If we fail to make such filings, or improperly document such filings, the validity of our title to a mineral property could be lost or challenged. If any of our mineral interests were challenged, we could incur significant costs in defending such a challenge. These costs or an adverse ruling with regards to any challenge of our titles could have a material adverse effect on our financial position or results of operations.
Our operations could be negatively affected by existing laws as well as potential changes in laws and regulatory requirements to which we are subject, including regulation of mineral exploration and ownership, environmental regulations and taxation.
The exploration and development of mineral properties is not withinsubject to federal, state, provincial and local laws and regulations in the controlcountries in which they are located in a variety of ways, including regulation of mineral exploration and land ownership, environmental regulation and taxation. These laws and regulations, as well as future interpretation of or changes to existing laws and regulations, may require substantial increases in capital and operating costs to us and delays, interruptions, or a termination of operations.
In the United States and the other countries in which we operate or own assets, in order to obtain permits for exploration or potential future development of mineral properties, environmental regulations generally require a description of the specific performanceexisting environment, including but not limited to natural, archeological and socio-economic environments, at the project site and in the region; an interpretation of the Named Executive Officers in achieving the objectives set by the Company. The key elementsnature and magnitude of potential environmental impacts that might result from such activities; and a description and evaluation of the compensationeffectiveness of the Named Executive Officersoperational measures planned to mitigate the environmental impacts. Currently, the expenditures to obtain exploration permits to conduct our exploration activities are outlined below. not material to our total exploration cost.
The Compensation Committee considers shareholder input when setting compensationlaws and regulations in all the countries in which we operate or own assets are continually changing and are generally becoming more restrictive, especially environmental laws and regulations. As part of our ongoing exploration activities, we have made expenditures to comply with such laws and regulations, but such expenditures could substantially increase our costs to achieve compliance in the future. Delays in obtaining or failure to obtain government permits and approvals or significant changes in regulation could have a material adverse effect on our exploration activities, our ability to locate economic mineral deposits, and our potential to sell, joint venture or eventually develop our properties, which could have a material adverse effect on our financial position or results of operations.
Occurrence of events for Named Executive Officers. Atwhich we are not insured may materially adversely affect our 2016 annual meetingbusiness.
Mineral exploration is subject to risks of shareholders, greater than 91%human injury, environmental liability and loss of assets. We maintain limited insurance coverage to protect ourselves against certain risks related to loss of assets for equipment in our operations and limited corporate liability coverage; however, we have elected not to have insurance for other risks because of the votes casthigh premiums associated with insuring those risks or for various other reasons including those risks where insurance may not be available. There are additional risks in connection with investments in parts of the world where civil unrest, war, nationalist movements, political violence or economic crisis are possible. These countries may also pose heightened risks of expropriation of assets, business interruption, increased taxation and a unilateral modification of concessions and contracts. We do not maintain insurance against political risk. Occurrence of events for which we are not insured could have a material adverse effect on our financial position or results of operations.
Severe weather or violent storms could materially affect our operations due to damage or delays caused by such weather.
Our exploration activities are subject to normal seasonal weather conditions that often hamper and may temporarily prevent exploration or development activities. There is a risk that unexpectedly harsh weather or violent storms could affect areas where we conduct these activities. Delays or damage caused by severe weather could materially affect our operations or our financial position.
Our business is dependent on the advisory vote on executive compensation weremarket price of certain commodities, particularly zinc, and currency exchange rates over which we have no control.
Our operations are significantly affected by changes in favorthe market price of commodities since the evaluation of whether a mineral deposit is commercially viable is heavily dependent upon the market price of the commodities related to any specific project. Because our core assets are currently in zinc related projects, the spot price of zinc is particularly important to the value of our executive compensation program.assets and future prospects. The Boardprice of Directorscommodities also affects the value of exploration projects we own or may wish to acquire or joint venture. These commodity prices fluctuate on a daily basis and are affected by numerous factors beyond our control. The supply and demand for commodities, the level of interest rates, the rate of inflation, investment decisions by large holders of these commodities, including governmental reserves, and stability of exchange rates can all cause significant fluctuations in prices. Currency exchange rates relative to the United States dollar can affect the cost of doing business in a foreign country in United States dollar terms, which is our functional currency. Consequently, the cost of conducting exploration in the countries where we operate, accounted for in United States dollars, can fluctuate based upon changes in currency exchange rates and may be higher than we anticipate in terms of United States dollars because of a decrease in the relative strength of the United States dollar to currencies of the countries where we operate. We currently do not hedge against currency or commodity fluctuations. The prices of commodities as well as currency exchange rates have fluctuated widely and future significant price declines in commodities or changes in currency exchange rates could have a material adverse effect on our financial position or results of operations.

Our business is dependent on key executives and the Compensation Committee reviewed these vote results and determined that, given the significant levelloss of support, no major re-examinationany of our executive compensation program was necessary at that time.

(1)Base Salary

The Compensation Committee attempts to provide base salary to the Named Executive Officers that is commensurate with their review ofkey executives could adversely affect our Peer Group Companies. The Compensation Committee fixed the base salary for the Named Executive Officers for 2016 (which commenced on January 1, 2016) during its meeting in September 2015. Increases or decreases in base salarybusiness, future operations and financial condition.

We are dependent on the Compensation Committee's evaluationservices of each individual Namedkey executives, including our Chief Executive Officer, performance,Christopher E. Herald, our Chief Operating Officer, Walter H. Hunt, and our Chief Financial Officer, James R. Maronick. All of those officers have many years of experience and an extensive background with Solitario and in the mining industry in general. We may not be able to replace that experience and knowledge with other individuals. We do not have "Key-Man" life insurance policies on any of our key executives. The loss of these persons or our inability to attract and retain additional highly skilled employees may adversely affect our business, future operations and financial condition.
Our business model relies significantly on other companies to joint venture our projects and we anticipate continuing this practice in the future. Therefore, our results are subject to the additional risks associated with the financial condition, operational expertise and corporate priorities of our joint venture partners.
Our Florida Canyon project and our Lik project are joint ventured with other mining companies that manage the exploration and development activities on the projects. We are the minority-interest party at Florida Canyon and a 50% partner at the Lik project, where Teck is the operator. Although our joint venture agreements provide certain voting rights and other minority-interest safeguards, the majority partner and/or operator not only manages operations, but controls most decisions, including budgets and scope and pace of exploration and development activities. Consequently, we are highly dependent on the operational expertise and financial condition of our joint venture partners, as well as their corporate priorities. For instance, even though our joint venture property may be highly prospective for exploration success, or economically viable based on feasibility studies, our partner may decide to not fund the further exploration or development of our project based on their respective financial condition or other corporate priorities. Therefore, our results are subject to the additional risks associated with the financial condition, operational expertise and corporate priorities of our joint venture partners, which could have a material adverse effect on our financial position or results of a peer group review,operations. Our Lik project requires unanimous consent by the performancejoint venture partners for annual budgets in excess of $1.0 million. Consequently, development of the entire Company relativeproject could be delayed without the unanimous consent of both parties to certain proposed actions or transactions.
We may look to joint venture with another mining company in the future to develop and/or operate our current or future projects; therefore, in the future, our results may become subject to additional risks associated with development and production of our foreign mining projects.
We are not currently involved in mining development or operation at any of our properties. In order to realize a profit from our mineral interests we have to: (1) sell our properties or interests outright at a profit; (2) form a joint venture for the project with a larger mining company with greater resources, both technical and financial, to further develop and/or operate a project; (3) develop and operate such projects at a profit on our own; or (4) create and retain a royalty interest in a property with a third party that agrees to advance the property toward development and mining. In the future, if our exploration results show sufficient promise in one of our foreign projects, not currently under joint venture, we may either look to form a joint venture with another mining company to develop and/or operate our projects or sell the property outright and retain partial ownership or a retained royalty based on the success of such project. Therefore, in the future, our results may become subject to the Company’s general goalsadditional risks associated with development and objectives,production of mining projects in general.
In the future, we may attempt to acquire a new property, or another company and the Company’s currentacquisition may require a substantial amount of capital or the issuance of Solitario equity to complete. Acquisition costs may never be recovered due to changing market conditions, or our own miscalculation concerning the recoverability of our acquisition investment. Such an occurrence could adversely affect our business, future operations and projected financial resources. No Named Executive Officers receive minimum base salary payments pursuantcondition.
We have evaluated a wide variety of acquisition opportunities involving mineral properties and companies for acquisition and we anticipate evaluating potential acquisition opportunities in the future. Some of these opportunities may involve a substantial amount of capital or the issuance of Solitario equity to successfully acquire. As many of these opportunities do not have reliable feasibility-level studies, we may have to rely on our own estimates for investment analysis. Such estimates, by their very nature, contain substantial uncertainty. In addition, economic assumptions, such as future costs and commodity prices, also contain significant uncertainty. Consequently, if we are successful in acquiring any employment agreement,new opportunities and our estimates prove to be in error, either through miscalculations or other written agreement. changing market conditions, this could have a material adverse effect on our financial position or results of operations.

However, given the unpredictability of the timing, nature and scope of information technology disruptions, we could potentially be subject to operational delays, the compromising of confidential or otherwise protected information, destruction or corruption of data, security breaches, other manipulation or improper use of our systems and networks or financial losses from remedial actions, any of which could have a material adverse effect on our cash flows, competitive position, financial condition or results of operations.
Failure to comply with the FCPA could subject us to penalties and other adverse consequences.
As a Colorado corporation, we are subject to the Named Executive Officers,FCPA and similar worldwide anti-bribery laws, which generally prohibit United States companies and their intermediaries from engaging in bribery or other improper payments to foreign officials for the purpose of obtaining or retaining business. Foreign companies, including some that may compete with our company, are not subject to U.S. laws and regulations, including the FCPA, and therefore our exploration, development, production and mine closure activities are subject to the disadvantage of competing against companies from countries that are not subject to these prohibitions.
In addition, we could be adversely affected by violations of the FCPA and similar anti-bribery laws in other jurisdictions. Corruption, extortion, bribery, pay-offs, theft and other fraudulent practices may occur from time-to-time in the countries outside of the United States in which we operate. Our mineral properties are located in countries that may have experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices.

Florida Canyon Zinc Project (Peru)
1. Property Description and Location
(Map of Florida Canyon Property formerly Bongará)
  On August 15, 2006, Solitario signed a Letter Agreement with Votorantim Metais Cajamarquilla, S.A., a wholly-owned subsidiary of Votorantim (now known as Nexa) (both companies are referred to in this Item 2 as "Nexa”) on Solitario's 100%-owned Florida Canyon zinc project (formerly called the Bongará project), On March 24, 2007, Solitario signed the Framework Agreement with Votorantim for the Exploration and Potential Development of Mining Properties, pursuant to, and replacing, the Florida Canyon Letter Agreement. In 2015 Votorantim transferred its sole discretion,interest in the Florida Canyon project to Compañía Minera Milpo S.A.A. (“Milpo”), an 80%-owned affiliate of Votorantim. In October of 2017, Milpo and Votorantim merged to form Nexa. Nexa completed an IPO raising $570 million and listed on the NYSE under the trading symbol NEXA and the TSX under the trading symbol NEXA. For the remainder of this Florida Canyon property section, all references to Votorantim, Milpo or Nexa will be collectively referred to as Nexa.
The Florida Canyon project consists of 16 concessions comprising 12,600 hectares of mineral rights originally granted to Minera Bongará S.A., our subsidiary incorporated in Peru. The property is located in the Department of Amazonas, northern Peru. Solitario's and Nexa’s property interests are held through the ownership of shares in Minera Bongará S.A., a joint operating company that holds a 100% interest in the mineral rights and other project assets. Solitario currently owns 39% of the Florida Canyon project.

During 2015 Nexa completed the steps required to earn a 61% interest in the Florida Canyon project, with Solitario retaining a 39% interest. Nexa may earn an additional 9% interest (up to a 70% shareholding interest) in Minera Bongará S.A., by sole-funding future annual exploration and development expenditures until a production decision is made. The option to earn the 70% interest can be exercised by Nexa at any time by committing to place the project into production based upon their evaluationa completed feasibility study. Nexa is the project manager. Once Nexa has committed to place the project into production based upon a feasibility study, it has further agreed to finance Solitario's 30% participating interest until production with a loan facility from Nexa to Solitario. Solitario will repay this loan facility through 50% of Solitario's cash flow distributions from the joint operating company. Solitario completed the funding of $1,580,000 of the individual Named Executive Officer in lightDrilling Program during 2019. The paid funding of the Drilling Program will be treated as an advance on Solitario’s commitment to fund 30% of any future construction development costs of Florida Canyon under the original joint venture agreement. Accordingly, in the event the Florida Canyon project is developed, which cannot be assured at this time, the funds paid to Nexa under this agreement will reduce the amount of Solitario’s obligation to fund 30% of future development costs, and / or repay loans from Nexa for future development costs at the Florida Canyon project.
According to Peruvian law, concessions may be held indefinitely, subject only to payment of annual fees to the government. In June 2020, payments of approximately $289,000 to the Peruvian government will be due in order to maintain the Florida Canyon mineral rights of Minera Bongará. Nexa is responsible for paying these costs as part of its earn-in expenditures. Peru imposes a sliding scale royalty varying from 1% to 12% of the operating profit of a mining operation. The percentage royalty is determined by rule based on the operating margin; however, the minimum royalty is 1% of the revenues.
From time to time Nexa may enter into surface rights agreements with individual landowners or communities to provide access for exploration work at the Florida Canyon project. Generally, these are short-term agreements.
Environmental permits are required for exploration and development projects in Peru that involve drilling, road building or underground mining. The requisite environmental and archeological studies were completed for all past work, but new studies are required for expanded activities planned for future years at the Florida Canyon project. Although we believe that these permits will be obtained in a timely fashion, the timing of government approval of permits remains beyond our control.
2. Accessibility, Climate, Local Resources, Infrastructure and Physiology
The Florida Canyon property is accessed from the coastal city of Chiclayo by the paved Carretera Marginal road, which is a heavily travelled paved national highway that passes approximately eight kilometers south of the deposit. The nearest town to the project is Pedro Ruiz located 15 kilometers southeast of the property. The area of the majority of past drilling and the most prospective mineralization, Florida Canyon, was previously inaccessible by road, the work to date having been done by either foot or helicopter access. Nexa has now completed approximately 30 kilometers of access road and Nexa is planning to complete the road access to the mineralized area of the project in 2020. Nexa maintains project field offices in Pedro Ruiz and a drill core processing facility and operations office in the nearby community of Shipasbamba.   
The project area elevation ranges between 1,800 and 3,200 meters above sea level. The climate is tropical with an average annual temperature of approximately 25oC. Mean annual rainfall exceeds one meter with up to two meters in the cloud forest at higher elevations. Most precipitation occurs during the rainy season, between November and April. Field work is considerably more difficult in the rainy season. Topography is steep, consisting of prominent escarpments and deep valleys. Dense jungle or forest vegetation covers the project area. With the exception of the partially completed access road and approximately 700 meters of tunneling, no infrastructure facilities have been constructed within the project area.
3. History
We discovered the Florida Canyon mineralized zone of the Florida Canyon Project in 1996. Subsequently, we joint ventured the property in December 1996 to Cominco (now Teck). Cominco drilled 80 core holes from 1997-2000. Cominco withdrew from the joint venture in February 2001, and Solitario retained its 100% interest in the project. We maintained the claims from 2001 to 2006, until the Florida Canyon Letter Agreement was signed. Nexa conducted surface drilling on an annual basis from 2006 to 2013 and from 2018 to 2019, and underground tunneling and drilling from 2010 to 2013. All significant work on the property has been conducted by our joint venture partners, Cominco and Nexa and, is described below in Section 5, “Prior Exploration.”
4. Geological Setting
The project is located within an extensive belt of Mesozoic carbonate rocks belonging to the Upper Triassic to Lower Jurassic Pucará Group and equivalents. This belt extends through the central and eastern extent of the Peruvian Andes for nearly 1000 km and is the host for many polymetallic and base metal vein and replacement deposits in the Peruvian Mineral Belt. Among these is the San Vicente Mississippi Valley Type (“MVT”) zinc-lead deposit that has many similarities to the Florida Canyon deposit and other MVT occurrences in the Project area.
The geology of the Florida Canyon area is relatively simple consisting of a sequence of Jurassic and Triassic clastic and carbonate rocks which are gently deformed into a broad northwesterly trending domal anticline. The MVT zinc-lead mineralization occurs in the carbonate facies of the Chambara (rock) Formation. This domal anticline is cut on the west by the Sam Fault and to the east by the Tesoro-Florida Fault.

5. Prior Exploration
We conducted a regional stream sediment survey and reconnaissance geological surveys leading to the discovery of the Florida Canyon area in 1996. The discovered outcropping mineralization is located in two deeply incised canyons within the limestone stratigraphy.
Subsequent to our initial work, Cominco conducted extensive mapping, soil and rock sampling, stream sediment surveys and drilling. This work was designed to determine the extent and grade of the zinc-lead mineralization, the controls of mineral deposition and to identify areas of potential new mineralization. Nexa began work in the fall of 2006 and drilled annually from 2006 through 2013. Underground exploration operations were conducted from 2011-2013. Since 2013 the most important work conducted consisted of continued access road construction and metallurgical testing. All work performed by us, Cominco, and Nexa was done by direct employees of the respective companies with the exception of the drilling, underground tunneling, helicopter services and road building, all of which were performed by third-party contractors under the direction of Cominco and Nexa.
6. Mineralization
Mineralization occurs as massive to semi-massive replacements of sphalerite and galena localized by specific sedimentary facies (rock strata) within the limestone stratigraphy and by structural feeders and karst breccias. More than three-quarters of mineralization is sulfide-dominant with the remainder being oxide-dominant. A total of 11 preferred beds for replacement mineralization have been located within the middle unit of the Chambara Formation. Mineralization is associated with the conversion of limestone to dolomite, which creates porosity and permeability within the rock formations. It is believed that mineralizing fluids passed through structurally controlled vertical feeder zones and into adjacent near-horizontal rock formations to produce mineralized vertical replacement bodies and stratigraphically controlled near-horizontal manto deposits. Drilling of stratigraphic targets has shown that certain parameters, includingcoarser-grained facies of the following:

(i)Bonuses based upon operational goals and parameters;
(ii)The desire, discussed above, to provide a substantial portion of compensation based on performance
(iii)The performance of the Company relative to Company goals including share price performance;
(iv)The financial strength of the Company, including liquid financial assets;
(v)The quality of mineral property assets, including exploration assets and mineral properties under joint venture; and
(vi)The financial strength and prospects for the smaller (junior) exploration mining industry.

stratigraphy are the best hosts for manto mineralization. Stratigraphically controlled mineralization is typically one to several meters in thickness, but often attains thicknesses of five to ten meters.

In establishing its goals

Karst features are localized along the feeder faults and locally produce "breakout zones" where mineralization may extend vertically across thick stratigraphic intervals where collapse breccias have been replaced by ore minerals. Mineralized karst structures are up to 50 meters in width (horizontal), up to 100 meters vertically, and up to hundreds of meters along strike.
Evidence for any particular year,these breakout zones is provided by the Compensation Committee strivesfollowing drill holes from various locations on the property:

San JorgeV-29756.622.691.1523.84
Dolomitization reaches stratigraphic thicknesses in excess of 100 meters locally. This alteration is thought to be related to the mineralizing event and is an important exploration tool. Continuity of the mineralization is demonstrable in areas of highest drilling density by correlation of mineralization within characteristic sedimentary facies, typical of specific stratigraphic intervals or within through-going observable structural zones in drill core. At Florida Canyon the high-angle mineralization occurs along well-defined northwest and northeast fracture systems. These structures occur in conjugate fractures, with N10º-50ºE trends present at a number of mineralized surface outcrops while trends of N50º-80ºW are identified at other showings.
7. Drilling
From 1997 through 2001, Cominco drilled 80 surface core holes totaling 24,696 meters. From 2006-2013, Nexa completed 309 surface core holes totaling 77,193 meters. From 2011-2013, Nexa completed 95 underground core holes totaling 15,144 meters. The underground drilling was conducted from 10 drill stations at generally 40-meter centers (two drill stations at 20-meter centers) and entirely within the San Jorge mineralized zone. Anywhere from three to 14 holes were drilled from each of the ten drill stations. The underground drilling was tightly spaced and designed to allow for feasibility-level reserve estimation.
From November 2018 to October 2019, Nexa completed a 39-hole, 17,033-meter core drilling program. The majority of holes were drilled 2019. The program had three major objectives: 1) extend the San Jorge near-vertical replacement body to the south and the adjacent near-horizontal manto bodies to the east; 2) offset previously drilled hole V-21 in the northern part of Florida Canyon to determine if it represented a significant near-vertical replacement body with horizontal mantos similar to the San Jorge Zone; and 3) extend horizontal mantos in the central and northern parts of the Florida Canyon drilling footprint. All three objectives were successfully achieved.

All past drilling conducted is within a footprint measuring approximately 2.5 kilometers long in a north-south direction and a little over a kilometer in an east-west direction. The entire drill pattern is within what we have informally labeled the Florida Canyon district. Within this district, several zones of strong zinc mineralization have been defined. The two zones with the largest amount of drilling are the San Jorge and the Karen-Milagros zones. We believe that additional detailed drilling of the newly delineated 1021 zone in the northern part of the Florida Canyon district has potential to add significant new resources. Drilling indicates that, for the most part, the entire Florida Canyon district remains open to expansion and the identified zones are interconnected.

8. Sampling, Analysis and Security of Samples
Core samples were transported from the drill by helicopter in sealed boxes to the processing facility in Shipasbamba where they were cut with a diamond saw. Half of the core was taken of intervals selected according to geologic criteria under the supervision of the geologist in charge and shipped in sealed bags by land. Cominco used SGS Laboratories and Nexa used ALS-Chemex, both in Lima, Peru, where all samples were analyzed by ICP. Any samples that contained greater than 1% zinc were then analyzed by wet chemistry assay for zinc and lead to provide a more accurate analysis of grade.
Since 2006, Nexa has been in control of all field activities on the project and is responsible for the security of samples. Nexa has indicated that there have been no breaches in the security of the samples. We have reviewed and engaged SRK Consulting (USA) Inc. (“SRK”) (a large independent international mining engineering firm) to review Nexa’s sampling procedures and believe that adequate procedures are in place to ensure the future security and integrity of samples. No breaches of security of samples are known to have occurred prior to Nexa’s work on the project.

9. Prefeasibility Studies
Nexa, either through its engineering staff or contracted independent mining engineering firms, has conducted prefeasibility-level studies to provide estimates of deposit size and grade, mining and processing recoveries, sizing of appropriate scale of operations, infrastructure design, and capital and operating cost estimates at a level of detail varying from preliminary economic assessment to prefeasibility levels. These studies were generally performed between 2007 and 2014.
Solitario and Nexa jointly completed a PEA for the entire project in 2017 that incorporated a variety of Nexa-generated studies into the goals provide both an incentiveanalysis. The PEA evaluation included resource estimation, mining and processing recovery estimates, a preliminary mining and processing plan, infrastructure layout, environmental considerations and an attainable goaleconomic analysis based on certain base case parameters. The PEA envisioned an underground mining operation with a 2,500 tonne per day floatation mill for processing, resulting in a 12.5-year mine life. It was assumed that provides shareholdersconcentrates would be trucked to Nexa’s Cajamarquilla zinc smelter facility in Lima Peru.
Metallurgical testing to evaluate metal recoveries and various processing options for mineralized material at Florida Canyon was conducted in 2010, 2011 and 2014. Tests to date on composited samples indicate zinc recoveries of 91.8% and lead recoveries of 81.9% in the San Jorge zone and zinc recoveries of 80.3% and lead recoveries of 71.7% in the Karen-Milagros zone. These recoveries represent averages for each zone based on sulfide dominant mineralization, but oxide material was present in the tested samples. Nexa also conducted a comprehensive geochemical testing program that demonstrated that zinc (and lead) recoveries were significantly affected by the Zn-sulfide/Zn-oxide ratio of mineralization. In general, mineralized material with greater than an 80% ratio of Zn-sulfide/Zn-oxide, recoveries are greater than 90% for Zn. Conversely, for mineralized material, with less than a 20% ratio of Zn-sulfide/Zn-oxide, recoveries are approximately 40% for Zn. Although sulfide recoveries achieved to date are very good, SRK suggests that optimization of processing and metallurgical parameters may result in improved recoveries and concentrate grade.
Other prefeasibility work completed by Nexa included drilling 16 diamond core holes in 2013 to evaluate geotechnical and hydrological parameters of the mineralized areas for both engineering and environmental purposes. In 2016, Nexa completed a geochemical/metallurgical study that more accurately defined the distribution of sulfide/oxide mineralization based on re-assaying of nearly all past drill-hole samples. This information was critical in resource estimation and accurately estimating metal recoveries.
The 2017 Florida Canyon Project PEA was completed by SRK on behalf of Nexa and Solitario in August of 2017. The NI 43-101 compliant study entitled: “Technical Report, Preliminary Economic Assessment, Florida Canyon Zinc Project,
Amazonas Department, Peru; Effective Date: July 13, 2017, Report Date: August 3, 2017;” can be found in the Company’s Canadian Sedar filings and is furnished in the Company’s U.S. Edgar filings.
10. Reserves and Resources
There are no reported mineral reserves.
11. Mining Operations
No commercial mining operations to recover metals have occurred on the project. However, in September 2010 Nexa initiated an underground tunneling program to access mineralization and completed its underground work in 2013. As of December 31, 2019, 700 meters of tunneling were completed.
12. Planned Exploration and Development
Nexa is currently working on a new NI-43101 compliant resource estimate incorporating the 2018-2019 drill hole assay results. This new estimate is expected to be completed by the end of the first quarter of 2020. Nexa is also planning to permit 84 new drilling platforms and associated interconnecting roads scattered over an area approximately six kilometers by five kilometers in 2020. These proposed platforms are located immediately south and southeast of the current Florida Canyon drilling footprint. Permitting is expected to take approximately one year. Drilling may be possible for the 2021 field season, depending upon the grant of permits and funding approvals by Nexa. Nexa is also planning to conduct a new metallurgical study beginning in the second quarter of 2020. This study is expected to be completed in the second quarter of 2020. In addition, Nexa plans to conduct additional road construction in 2020 to access local communities as part of their social commitment to these communities.

Lik Project (Alaska)
1. Property Description and Location
(Map of Lik Property) Lik.jpg
The Lik property consists of 47 contiguous Alaska state mining claims. The contiguous claims have been grouped together for the purpose of working and operating under a common plan of development for the benefit of all of the claims. The claims cover an area of approximately 6,075 acres (2,460 ha). The claims are located in the southwestern DeLong Mountains in the Wulik River drainage.
To retain the state claims, the Company is required to make annual rental payments to the State of Alaska. The estimated rental payments for 2020 are $7,000. Property holders are also required to perform assessment work with the opportunityamount dependent on the area of the State claims. Excess assessment expenditure credits may be carried forward for returna maximum of four years. If required, payments may be made in lieu of work to allow retention of the property for a period of five consecutive years. The geographical coordinates of the Lik deposit are approximately 163o 12’ W and 68o 10’ N. The figure above illustrates the location of the Lik property.

2. Acquisition History and Joint Venture Arrangement
Solitario acquired its 50% interest in the Lik property from the acquisition of Zazu Metals Corp (“Zazu”) on their investment while minimizing corporateJuly 12, 2017. As a result of the Acquisition, Zazu became a wholly owned subsidiary of Solitario. Prior to that, Zazu acquired its 50% interest in the Lik property from GCO Minerals Company, a wholly owned subsidiary of the International Paper Company (“GCO”), on June 28, 2007 by making a cash payment to GCO of $20,000,000 and shareholder riskgranting GCO a 2% net proceeds interest. GCO also owns an additional 1% net profits interest in the Lik property from a 1997 agreement.
The Company is participating in the exploration and possible development of the Lik property through a joint venture with Teck American Incorporated (50%), a wholly owned subsidiary of Teck Resources Limited (collectively “Teck”). The terms of the joint venture were governed by the Lik Block Agreement, made as of January 27, 1983, between Houston Oil & Minerals Exploration Company (“HOMEX”) and GCO. HOMEX assigned its interest in the Lik Block Agreement to Echo Bay Mines Ltd., which, in turn, assigned such interest to Teck.
Under the terms of the Lik Block Agreement, GCO held a 50% interest, and the right to increase its interest to up to 80% provided that GCO met an inflation-adjusted work commitment. The required expenditure amount was originally $25 million when defined in 1983 and increased with inflation indexing and escalations to approximately $43 million at the time Solitario acquired Zazu. As of January 27, 2018, we estimated that approximately $22 million had been incurred towards the inflation adjusted $43 million expenditure required to earn an additional 30% interest in the property.
As the Company did not spend the full inflation-adjusted expenditure amount by January 27, 2018, the Lik Block Agreement terminated. Consequently, as of December 31, 2019, Teck retains its 50% participating interest in the Lik property, and Teck and Solitario are negotiating a new a joint operating agreement that will govern all further operations relating to the extent possible. Although certain targetsLik property. We anticipate that under such joint operating agreement, Solitario, as successor to GCO, may be the operator and goals related certain operational goals, suchmay have full and exclusive control of the Lik property, its facilities and production as well as the exploration, development and mining undertaken pursuant to potential property acquisitions and/or potential merger or acquisition activities, if any, are confidential, the Compensation Committee has structured these typesLik Block Agreement. The current agreement requires unanimous approval by the parties for annual expenditures in excess of goals$1 million. In July 2018, the Company and Teck signed a Joint Exploration Agreement (“JEA”) whereby both parties agreed to fund a surface exploration program on a 50%-50% basis for 2018. In January 2019, the Company and Teck signed an Addendum to extend the JEA to January 31, 2020. However, pending the completion of a new joint operating agreement, an extension to the JEA is expected to be reasonable and obtainable by our Named Executive Officers, without undue risksigned prior to the assets of Solitario. Due to the nature of Solitario's corporate activities relating to (i) the evaluation of mineral properties for acquisition; (iii) the evaluation of strategic opportunities for a corporate merger, acquisition or sale; (iii) the saleend of the Mt.

3. Accessibility, Climate, Local Resources, Infrastructure and Physiology
Access to the Lik property is by air to a gravel surfaced airstrip located on the property. The airstrip is capable of handling multi-engine cargo planes. Charter flights may be arranged from a number of sites in northwestern Alaska. The town of Kotzebue, which is located about 90 miles from the deposit, is a seaport with commercial air service from Anchorage. Kotzebue is the center for access to the nearby Red Dog mine operated by Teck.
The nearest location for which climatic data is available is the town of Kotzebue. The average annual temperature at Kotzebue is 21.6oF, with seasonal extremes ranging between 77oF in summer to -58oF in winter. There is an average of nine inches of rain and 47 inches of snowfall per year. Snow falls are not extreme but blowing snow may form significant drifts. Strong winds are common in most parts of Alaska. Diamond drilling is possible at the Lik property between June and October.
The exposures of mineralization at the Lik property are located at about 800 feet above sea level. West of the deposit, the land rises steeply to peaks about 2,300 feet above sea level. To the southeast, the land slopes down to the Wulik River where the bottom of the valley is about 700 feet above sea level. There is sufficient space for tailings and waste rock disposal, and sufficient water is expected to be available for any proposed processing. Locally, there is vegetation on the property consisting of tundra grasses and low brush made up of willow, dwarf birch, and alder.
There is a camp located on the Lik property. The camp has been used periodically over the last twelve years and was substantially refurbished as a part the 2007 and 2008 field programs. The supply of electric power and workforce accommodation will have to be developed. There are no local resources adjacent to the Lik property. The Red Dog mine, operated by Teck, is located about 13.6 miles southeast of the deposit. Potentially, concentrates could be moved along the access road from the Red Dog mine to the port on the Chukchi Sea. The port has a shipping season in excess of 100 days.
Zazu entered into an agreement with Alaska Industrial Development and Export Agency (“AIDEA”) to enable AIDEA to begin due diligence on the proposed expansion of the port and the Red Dog road, the Delong Mountain Transportation System (“DMTS”), to potentially handle Lik concentrates. AIDEA, as owners of the DMTS, evaluated their possible role in the two parts of the proposed expansion project: the financing of a spur road connecting the Lik project to the DMTS, and the financing of any required modifications at the discretionport. The DMTS is open to multiple users such as the Company. The studied expansion would facilitate both the development of the Compensation Committee. AsLik project and handle future concentrate production from the project. The DMTS road and port system currently handles all concentrate produced by the Red Dog zinc mine of Teck. Prior to the AIDEA agreement, Zazu received a letter of Non-Objection from the Northwest Arctic Borough (“NWAB”). In this letter, the NWAB formally acknowledged its awareness of the Lik project, and that NWAB had no objection to the project.
In January 2015, AIDEA announced the completion of its study into capacity availability in its DMTS. The report concluded that there is sufficient excess capacity for the Company’s concentrate shipping needs, confirming the assumptions made in Zazu's 2014 PEA. This study aimed to closely identify the outputs of both Lik and Red Dog, if any modifications are required to the DMTS to support them, and if so, their potential cost. The study concluded that sufficient handling capacity will exist with only minor modifications required to accommodate future planned production from Lik under the analyzed PEA scenario.

4. History
The Red Dog ore deposit was originally discovered in 1970 by a geologist undertaking mapping in the De Long Mountains area on behalf of the United States Geological Survey. GCO, in joint venture with New Jersey Zinc Company and WGM Inc., carried out stream geochemical sampling and reconnaissance for color anomalies. Claims were staked in July 1976 to cover a stream geochemical anomaly on Lik Creek. HOMEX replaced New Jersey Zinc Company in the joint venture in 1976/1977.
Diamond drilling on the Lik property commenced in 1977 and targeted a gossan with a coincident soil and electromagnetic anomaly. The first hole encountered massive lead-zinc-silver-bearing sulfides. By the end of 1977, the joint venture had completed 25 line-miles of ground geophysics, a soil sampling program, and ten diamond drill holes with an aggregate depth of 5,260 feet. In 1978 and 1979, further geological, geochemical and geophysical surveys were carried out, together with the drilling of another 93 diamond drill holes aggregating 51,200 feet. A mineral resource was estimated. The joint venture continued to work in the district in the period 1980 to 1983. However, only limited diamond drilling activity continued on the Lik property. The Lik Block Agreement was signed in 1984.
In 1984, Noranda optioned the GCO holding of the Lik property. Much of Noranda’s activity was concentrated in the Lik North Area where ten diamond drill holes with an aggregate depth of 13,710 feet were completed on four sections. Noranda also drilled holes in the Lik South deposit to better define the deposit. Noranda released its interest in the Lik property after a re-organization of its holdings in the United States. From 1985 through June of 2007, when Zazu acquired its interest in the Lik property, only a limited amount of work was conducted at Lik.
Zazu completed diamond drilling programs during the 2007, 2008 and 2011 summer field seasons. From 2009 through 2014, Zazu conducted a suite of economic, engineering, environmental and metallurgical studies on the Lik property, culminating with the completion of a PEA in 2014.
5. Geological Setting
The regional geology of the Western Brooks Range area is structurally complex. The sedimentary rocks of the area have been significantly disrupted by thrust sheets. The Lik property and the other zinc-lead deposits of the Brooks Range, including Red Dog, are hosted in the Kuna Formation of the Lisburne Group. In the Western Brooks Range, the Lisburne Group includes both deep and shallow water sedimentary facies and local volcanic rocks. The rocks have been extensively disrupted by thrusting. The deep-water facies of the Lisburne Group, the Kuna Formation, are exposed chiefly in the Endicott Mountains.
On a district scale, the Lik property is hosted in the Red Dog plate of the Endicott Mountains thrust sheet. The stratigraphically lowest rocks within the Red Dog plate belong to the Kayak Shale. The top of the Kayak Shale is interbedded with rocks of the Kuna Formation. The Ikalukrok Unit has been divided into a lower laminated black shale sub-unit and an upper medium- to thick-bedded black chert sub-unit. The Ikalukrok Unit hosts all of the massive sulfide deposits in the area.
Locally, the Lik property is hosted in the upper part of the Ikalukrok Unit of the Kuna Formation. The host rocks are carbonaceous and siliceous black shale, with subordinate black chert and fine-grained limestone. These rocks strike broadly north-south and dip at about 25o to 40o to the west. The massive sulfides are overlain conformably by rocks of the Siksikpuk Formation. The sequence is overridden by allochthonous rocks that form high hills north and west of the deposits.
The mineralized sequence is cut by a number of faults. The most significant disruption is the Main Break Fault, which drops the northern end of the Lik deposit down about 500 feet. It is unclear whether there is a change in strike north of the fault, or whether the change is more apparent due to topography. The Main Break Fault strikes east-west and dips north at about 60o. There is another group of steeper faults that tend to strike northerly or northwesterly and which are interpreted as being both normal and reverse with throws of up to 330 feet.
6. Prior Exploration and the Results of the 2019 Exploration Program
The Red Dog ore deposit was originally discovered in 1970 by a geologist undertaking mapping in the De Long Mountains area on behalf of the United States Geological Survey. The Lik deposit was discover by GCO in the mid-1970’s by following up on soil color and stream geochemical anomalies. From the late 1970’s to 2011, various geochemical, geophysical and geologic activities were intermittently conducted to define drill targets. The Lik property was sporadically drill tested from the late-1970’s to 2011 by seven different companies. Details of these historical drilling campaigns are discussed above In Decemberunder the heading “History” and below under the heading “Drilling.”
The 2019 exploration program consisted of 2016,geologic mapping, geochemical sampling, re-logging of old core, XRF analysis for trace elements in old core, reinterpretation of the Compensation Committeestratigraphic and structural setting in the vicinity of the Lik deposit and ground gravity geophysical surveying. The geologic mapping program resulted in a better understanding of the stratigraphic and structural control of mineralization at Lik, and the potential trend of mineralization to the north. Geochemical sampling indicates an area of elevated geochemistry to the north that could be proximal to zinc mineralization. The gravity survey results are somewhat uncertain, but may point to an area of interest, also to the north. The stratigraphic and structural reinterpretation in the vicinity of the Lik deposit suggests the potential for stacked deposits below the Lik deposit.

7. Mineralization
The Lik deposit is a black shale-hosted stratiform zinc-lead-silver sedimentary-exhalitive (SEDEX) deposit. Mineralization is syngenetic with respect to sediment deposition. Silicification occurs within and peripheral to the main mass of sulfides. Major sulfides in decreasing order of abundance are pyrite-marcasite, sphalerite and galena. The ore textures are massive, fragmental, chaotic, and veined; they rarely show typical sedimentary layering. The portion of the ore body near the surface is oxidized. The deposit is continuous outside the Lik property onto the adjacent 100%-owned Teck property to the south. The southern continuation of the Lik deposit is referred to as the Su deposit, lying on Teck’s Su property.
Within the Lik property, the deposit is divided into two parts by the Main Break Fault. The main part of the deposit within the existing claims is referred to as the Lik South deposit. As presently tested, the Lik South deposit has a surface footprint of about 3,600 feet long and about 2,000 feet wide. It has been tested down dip to a depth of about 650 feet. The Lik South deposit remains open down dip. North of the Main Break Fault, the Lik North deposit has a surface footprint of about 2,300 feet long and about 1,150 feet wide. It has been tested down dip to a depth of about 1,000 feet. The Lik North deposit remains strongly open down dip and to the north.
The deposits strike northerly and dip westerly at about 25o to 40o. The mineralization comprises irregular, stratiform lenses. The mineralogy of the sulfides is simple and comprises pyrite, marcasite, sphalerite, and galena. Gangue minerals include quartz (as chert), clay minerals, carbonate and barite. Noranda recognized six different ore types in its logging of drill core. Typical grades of mineralized intersections within the Lik deposit are listed in the table below:

Previous work by GCO determined that no bonus was earnedsulfides were deposited in four distinct cycles. Individual cycles may be quite thin near the margins of the deposit and the thickest accumulation in a single cycle noted to date is about 45 feet thick. The base of a sulfide cycle begins abruptly with the deposition of sphalerite, galena and pyrite. Typically, the highest grades are found at or within 5-10 feet of the base of a sulfide cycle. In the central portion of the deposit several cycles are stacked and comprise a cumulative thickness of up to 100 feet of mineralization.

Zazu completed two diamond drilling programs during the year ended2007 and 2008 to further test the Lik South deposit and to obtain samples for metallurgical testing. At the end of 2008, most of the Lik South deposit had been tested on lines spaced at 200 ft. with holes spaced at about 100 ft.
The 2011 drilling program at Lik combined exploration and development drilling. The exploration drilling focused on improving resource definition, in particular near the transition zone between Lik South and Lik North and also Lik North. The development drilling focused on obtaining additional metallurgical samples and geotechnical drilling for the open pit design and foundation information to assist in infrastructure design. By the end of 2011, a total of approximately 38,328 meters (125,700 feet) of drilling in 229 holes had been completed on the Lik property by the Company (Zazu) and the previous owners. No drilling has been completed on the Lik project since 2011.
9. Sampling, Analysis and Security of Samples
Pre-Zazu Drilling
Core recoveries were typically high within the massive sulfides, but lower, more variable recoveries were obtained in the unmineralized and weakly mineralized sections. The entire core obtained from the Lik deposit, usually NQ-size, was logged on site. All of the core containing sulfide mineralization was cut using diamond saws and half of the core was sent for assay. Reference samples were not included in the sample stream. Sample lengths in massive sulfides were typically from two to three feet, but occasionally up to nine feet. Sample lengths were probably controlled by geology and the location of depth markers in the core boxes.
Most of the samples were assayed by Bondar Clegg Laboratory Group (“Bondar Clegg”) of Vancouver. At various times, the laboratory-maintained preparation facilities in Anchorage and Fairbanks Alaska. In the initial years, when the bulk of the drilling was completed, it is believed that sample preparation and analysis were carried out in Vancouver. Bondar Clegg was not a registered laboratory at that time. However, Bondar Clegg was a recognized, reputable laboratory and was experienced in the use of atomic absorption spectrophotometry.
As the entire core was logged and sampled in an isolated field camp, security was not a major concern because access to the camp was closely controlled. It is noted that four different companies (WGM, GCO, Noranda and Moneta) have completed drilling programs at the Lik property and all of them have obtained consistent results. The work was considered completed to industry standards in use at the time of the work. Sample preparation was completed in the assay laboratory.

Zazu Drilling
Drill core obtained during the 2007, 2008 and 2011 drilling campaigns was logged on site. The entire core containing sulfide mineralization was sawn using diamond saws and half of the core was sent for assay. All massive and high-sulfide cores were sampled. Visual methods were used to select sample boundaries and lengths. The mineralization at Lik is considered to be appropriately logged and sampled. It is not evident that logging or sampling is leading to any bias in the sample results. An examination of logging showed that core recovery in sulfide areas was generally very high.
Core drilled in 2007 was placed in the sample bags, the air was evacuated and replaced with nitrogen. The samples were sent to Kotzebue by charter and then by licensed carrier to Anchorage. The samples were stored under refrigeration in Anchorage. The samples were dispatched to G & T Metallurgical Services Ltd. (“G & T”) of Kamloops, British Columbia, an ISO 9001:2000 certified laboratory for precious metals and base metals. As well as completing metallurgical testing, G & T crushed and analyzed the samples. The 2008 diamond drill core was not required for metallurgical testing and core was handled normally. Sawn samples were securely bagged and boxed on site and dispatched to a facility of ALS Laboratory Group (“ALS Chemex”) located in Fairbanks, Alaska, for sample preparation. Transportation of the samples was through third-party companies that provided secure transportation services. The pulps were analyzed at ALS Chemex located in Fairbanks or Elko, Nevada. Zazu did not participate in any part of the sample preparation or analysis except for cutting core.
Check samples from the 2007 drilling program and all samples from the 2008 drilling campaign were sent to the preparation and assaying facilities of ALS Chemex (ISO 17025 accreditation). Other QA/QC procedures employed by Zazu included the use of blanks (unmineralized core from outside of the mineralized zone) and quartered core duplicates. Zazu was unable to obtain acceptable reference samples for the 2007 field season and reference samples were not included as part of the 2007 ongoing QA/QC program. Reproducibility between G & T and ALS Chemex was found to be good. A detailed description of QA/QC procedures can be found in the Solitario’s Canadian SEDAR filings and in the Company’s US Edgar filings: Technical Report; Zazu Metals Corporation, Lik Deposit, Alaska, USA; Report Date: April 23, 2014; Effective Date: March 3, 2014; prepared by JDS Energy and Mining Inc (“JDS”).

10. Prefeasibility Studies
Zazu completed a PEA in 2014 that incorporated a variety of prefeasibility level studies into the analysis. These studies included resource estimation, mining and processing recovery estimates, a preliminary mining and processing plan, infrastructure layout, environmental considerations and an economic analysis based on the base case parameters. The PEA envisioned an open pit mining operation with a 5,500 ton per day floatation mill for processing resulting in a nine-year mine life. Concentrates would be handled through the DMTS road and port system that currently handles all concentrate produced by the nearby Red Dog zinc mine of Teck. A summary of metallurgical testing and mineral processing is provided below. The PEA analyzed the Lik project as a stand-alone operation building its own independent processing, tailings and port facilities.
Zazu engaged JDS to complete the PEA on the Lik deposit in 2013. The NI 43-101 compliant study entitled: “Technical Report; Zazu Metals Corporation, Lik Deposit, Alaska, USA; Report Date: April 23, 2014; Effective Date: March 3, 2014;” can be found in the Company’s Canadian Sedar filings and is furnished in the Company’s U.S. Edgar filings. JDS is a Canadian independent and internationally recognized mining engineering firm providing engineering services internationally.
Metallurgical Testing and Mineral Processing

There have been five metallurgical test work reports issued to date on the Lik ores. The most recent and comprehensive processing and metallurgical testing programs include work performed by G&T and by SGS. Samples collected during drilling in 2007 and 2008 were composited into one Master Composite for testing at G&T in 2008, and later testing by SGS was carried out in 2010 on the remainder of the Master Composite. These key testing results have formed the basis for this economic evaluation of the Lik deposit. Results are summarized in the table below:

The metallurgical flowsheet for this PEA includes conventional crushing, grinding, and flotation processing methods. Run-of–Mine (ROM) ore will be delivered to a primary crushing plant and stored in a coarse ore stockpile awaiting reclaim into the grinding circuit. Crusher ore will be reclaimed and delivered to a two-stage grinding circuit equipped with a Semi-Autogenous Grinding (SAG) mill and a ball mill in closed circuit with cyclones.
Recoveries from these modeled methods and metallurgical testing conducted to date are anticipated to be 85% of zinc to the zinc concentrate and 69.7% of the lead to the lead concentrate. Silver is also recovered and payable at times in the zinc concentrate and more significantly in the lead concentrate.
11. Reserves
There are no reported mineral reserves.
12. Mining Operations
No commercial mining operations to recover metals have occurred on the project.
13. Planned Exploration and Development
Solitario and Teck are in discussions to jointly fund a 2020 exploration program with Teck acting as project operator. The program, if approved, consists of drilling two or three core holes totaling approximately 1,000 meters. Drill targets under consideration include an area approximately one kilometer north of Lik and also below the Lik deposit to test for stacked mineralized horizons. Drilling is expected to begin during the 2020 summer field season. We expect to reach a final decision on this program during the first quarter of 2020.

Chambara Zinc Property (Peru)
In April 2008, we signed the Minera Chambara shareholders’ agreement with Votorantim on Solitario's 100%-owned Chambara zinc project. In 2015 Votorantim transferred its interest in the Chambara project to Milpo, now Nexa. In October of 2017, Milpo and Votorantim merged to form Nexa. For the remainder of this Chambara property section, all references to Votorantim, Milpo or Nexa are collectively referred to as “Nexa.”
 The original purpose of the Chambara joint venture was to collectively pool independently owned Solitario
and Nexa properties into a jointly held joint venture. These properties were located within a large area of interest in northern Peru measuring approximately 200 by 85 kilometers, but outside of the Florida Canyon property position. Nexa originally contributed 52 mineral concessions within the area of interest totaling 52,000 hectares to Minera Chambara for a 15% interest in Minera Chambara. We contributed 9,600 hectares of mineral claims and an extensive exploration data base in our possession for an 85% interest in Minera Chambara. Existing and future acquired properties subject to the terms of the shareholders’ agreement will be controlled by Minera Chambara. Minera Chambara dropped selected concessions in 2013 and 2016 and acquired the rights to 13 new concessions totaling 11,600 hectares in 2017. This resulted in Minera Chambara holding 36,400 hectares of valid concessions that completely surround the Florida Canyon project area held by Minera Bongará. As of December 31, 20162019, Minera Chambara’s only assets are the properties and Minera Chambara has no debt. Nexa may increase its shareholding interest to 49% through cumulative spending of $6,250,000 and may further increase its interest to 70% by funding a feasibility study and providing for construction financing for Solitario's interest. If Nexa provides such construction financing, we would repay that financing, including interest, from 80% of Solitario's portion of the Named Executive Officers would notproject cash flow.
 The project has been on care and maintenance in recent years. Significant geochemical anomalies and outcropping mineralization have been identified at several locations on the Chambara property. Nexa is responsible for maintaining the property in good standing and making all concession payments to the Peruvian government. Concession costs in 2020 to be paid a bonusby Nexa are estimated to be $527,000.
La Promesa Project (Peru)
The La Promesa property, acquired in 2008, consists of three concessions totaling 2,600 hectares. Currently, our only holding costs for the year ended 2016mineral rights are annual payments of nine dollars per hectare to the Peruvian government. Total holding costs in 2020 will be approximately $34,000. A subsidiary of Newmont holds a 2% net smelter return (“NSR”) on the property.
During the past several years Solitario has conducted an active social engagement program with the community located near the La Promesa project area with the objective of obtaining a community agreement to support exploration activities, including drilling. To date, no agreement has been signed and we are planning to conduct limited exploration activities on the property in 2020. In Peru, a community agreement is required in order to obtain drilling permits. During 2020 our objectives are to complete an agreement with the local community, to conduct surface exploration, and if warranted, conduct a drilling program.
At least five high-grade polymetallic veins have been identified and sampled at surface. Two of the veins, about 300 meters apart, have been traced for at least 400 meters along strike. There appears to be a systematic trend towards greater vein thickness with depth, as the widest observed vein in outcrop occurs at the lowest elevation sampled to date. Channel sampling along 300 meters of strike length from the best exposed vein yielded the following high-grade results:

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities
Our common stock trades on the NYSE American exchange under the symbol “XPL” and on the TSX under the symbol “SLR.” Since 2008 trading volume of our common stock on the NYSE American exchange has exceeded the trading volume of our stock on the TSX by a substantial margin.
Shares authorized for issuance under equity compensation our Named Executive Officers have historically received is in the form of stock options granted pursuant to the 2006 Stock Option Incentive Plan (the “2006 Plan”) andplans
On June 18, 2013 Solitario’s shareholders approved the 2013 Solitario Exploration & Royalty Corp. Omnibus Stock and Incentive Plan (the “2013 Plan”), with. On June 29, 2017, Solitario shareholders approved an amendment to the 2013 Plan, which increased the number of shares available of common stock for issuance under the 2013 Plan from 1,750,000 to 5,750,000. Under the terms of the 2013 Plan, the Board of Directors may grant awards to directors, officers, employees and consultants. Such awards may take the form of stock options, stock appreciation rights, restricted stock, and restricted stock units. The terms and conditions of the awards are pursuant to the 2013 Plan and options are granted by the Board of Directors or a committee appointed by the Board of Directors.
On September 1, 2017, the Board of Directors granted, subject to shareholder approval at the next meeting of shareholders, 2,300,000 stock options under the 2013 Plan to officers and members of the Board of Directors (the “Conditional Options”). The Conditional Options were approved by Solitario’s shareholders at Solitario’s annual meeting on June 19, 2018. The Conditional Options have a five-year life, an exercise price of such options equal to the current market$0.77 per share, and a grant date fair value of our Common Stock at$970,000, based upon a Black-Scholes model with a volatility of 64%, and a risk-free interest rate of 1.70%. The Conditional Options vest on the schedule of 25% on date of grant. The Compensation Committee believes that a portion of our Named Executive Officers’ compensation should be performance based and tied to the long term valueapproval of the Company. The Compensation Committee also believes that our compensation policies should be fair to our shareholders,grant (June 19, 2018) and be focused25% on our long-term viability. The Compensation Committee believes the granting of stock options or other forms of equity based compensation aligns the interestseach of the Named Executive Officers and our shareholders and provides the incentive to manage the Company from the perspective of an owner of the Company. In addition, the Compensation Committee believes the vesting terms of the stock options granted from the 2013 Plan, discussed below, provide that a significant portion of the compensation will be received at a future date, which provides a tempered longer-term incentive for our Named Executive Officers as well as an incentive for them to remain with the Company.

The amount of all individual grants and the grant date of the stock options have been determined periodically by the Compensation Committee or by the full Board. All grants to date are asnext three anniversary dates of the date of grant (September 1, 2018, 2019 and 2020).

On November 1, 2018, the approval by the Compensation Committee (or the full Board if requested by the Compensation Committee) at the fair market value on the date of grant. To date, all option grants from the 2006 Plan andDirectors granted 1,623,000 stock options under the 2013 Plan vestPlan. These options have a five-year life, vested 25% on the date of grant and the remaining options vest at 25% per year on the anniversaryeach of the next three anniversary dates of the date of grant, overand have an exercise price of $0.31 per share, and a three-year period. grant date fair value of $282,000, based upon a Black-Scholes model with a an expected volatility of 64%, and a risk free interest rate of 2.98%.
On July 28, 2016January 24, 2019, the Board of Directors granted 1,699,000150,000 stock options under the 2013 Plan, which included 450,000Plan. These options to Mr. Herald, 330,000 options to Mr. Hunt,have a five-year life, vested 25% on the date of grant and 309,000 options to Mr. Maronick. On August 24, 2016,vest 25% on each of the next three anniversary dates of the date of grant, and have an exercise price of $0.28 per share, and a grant date fair value of $23,000, based upon a Black-Scholes model with a an expected volatility of 64%, and a risk free interest rate of 2.4%.

On October 28, 2015, the Board of Directors authorized a share repurchase program pursuant to which Solitario may acquire up to 2 million of its common shares. All purchases listed were made in open-market transactions through a broker dealer. During 2019 the Board of Directors extended the termination date of the repurchase program to December 31, 2020; however, the repurchase program may be suspended or discontinued at any time and does not obligate Solitario to acquire any particular amount of our shares. During the years ended December 31, 2019 and 2018, we purchased 38,400 and 263,100 shares of Solitario common stock, respectively, for an aggregate purchase price of $13,000 and $101,000, respectively. As of December 31, 2019, we have purchased a total of 969,300 shares of Solitario common stock for an aggregate purchase price of $462,000 under the share repurchase program since its inception.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with the information contained in the consolidated financial statements and notes thereto included in Item 8, "Financial Statements and Supplementary Data." Our financial condition and results of operations are not necessarily indicative of what may be expected in future years.
(a). Recent Developments
On January 22, 2019, we completed the sale of our interest in certain royalties to SilverStream SEZC, a private Cayman Island royalty and streaming company (“SilverStream”), for Cdn$600,000 (the “Royalty Sale”). The Royalty Sale covered (i) a royalty on the formerly Solitario-owned 125,000-acre polymetallic Pedra Branca palladium, platinum, gold, nickel, cobalt and chrome project in Brazil, (ii) a royalty covering 3,880 acres of non-producing exploration properties in Mexico, and (iii) a purchase option on royalties covering 11 separate non-producing properties covering over 16,500 acres in Montana. At the closing of the Royalty Sale, Solitario received Cdn$250,000 in cash and a convertible note from SilverStream in the principal amount of Cdn$350,000 (the “SilverStream Note”). The SilverStream Note was originally due December 31, 2019, accrued 5% per annum simple interest, payable on a quarterly basis, and is convertible into common shares of SilverStream, at the discretion of SilverStream, by providing a notice to us of conversion. In December of 2019, Solitario and SilverStream agreed to extend the due date of the SilverStream Note to June 30, 2020, and to increase the interest rate to 8% per annum simple interest. All other terms of the SilverStream Note remained the same. SilverStream may only provide a notice of conversion if SilverStream has completed an initial public offering during the term of the SilverStream Note for minimum proceeds of Cdn$5,000,000; otherwise the SilverStream Note will be payable in cash at the maturity date. Pursuant to the terms of the SilverStream Note, if SilverStream were to complete an initial public offering and the SilverStream Note was converted, we would receive common shares converted at 85% of the weighted average quoted price of a share of SilverStream common stock for the most recent 10-day period prior to the notice of conversion. During 2019, we recorded mineral property revenue of $408,000 for the Royalty Sale, consisting of the fair value of the cash received on the date of the sale of $185,000 and the fair value of the SilverStream Note on the date of the sale of $263,000 less the carrying value of the royalties sold of $40,000. We recorded interest income of $12,000 from the SilverStream Note during 2019. As of December 31, 2019, the SilverStream Note was recorded at $268,000, based upon the current US dollar / Canadian dollar exchange rate, and Solitario recorded a credit to exchange gain of $5,000, included in general and administrative expense during 2019.
(b). Business Overview and Summary
We are an exploration stage company at December 31, 2019 under Industry Guide 7, as issued by the SEC. We were incorporated in the state of Colorado on November 15, 1984 as a wholly owned subsidiary of Crown Resources Corporation ("Crown"). In July 1994, we became a publicly traded company on the Toronto Stock Exchange (the "TSX") through our initial public offering. We have been actively involved in mineral exploration since 1993. Our primary focus is the acquisition and exploration of zinc-related exploration mineral properties. However, we continue to evaluate other mineral properties for acquisition, and we hold a portfolio of mineral exploration properties and assets for future sale, joint venture or to create a royalty up to the development stage of the project (development activities include, among other things, completion of a feasibility study for the identification of proven and probable reserves, as well as permitting and preparing a deposit for mining). At that point, or sometime prior to that point, we would likely attempt to sell a given mineral property, pursue its development either on our own, or through a joint venture with a partner that has expertise in mining operations, or obtain a royalty from a third party that continues to advance the property. Although our mineral properties may be developed in the future by us, through a joint venture or by a third party, we have never developed a mineral property. In addition to focusing on its mineral exploration properties and the evaluation of mineral properties for acquisition, Solitario also evaluates potential strategic corporate transactions as a means to acquire and interest in new precious and base metal properties and assets with exploration potential as well as other potential corporate transactions and combinations determined to be favorable to Solitario.
Our geographic focus for the evaluation of potential mineral property assets is in North and South America; however, we have conducted property evaluations for potential acquisition in other parts of the world. At December 31, 2019, we consider our carried interest in our Florida Canyon project in Peru and our interest in the Lik project in Alaska to be our core mineral property assets. In addition, at December 31, 2019, we have one exploration property in Peru. We are conducting independent exploration activities in Peru and through joint ventures operated by our partners in Peru and the United States. We conduct potential acquisition evaluations in other countries of both South and North America.
As of December 31, 2019, we have significant balances of cash and short-term investments that we anticipate using, in part, to fund planned 2020 exploration, to further the exploration of our Lik project, conduct exploration on the La Promesa project in Peru, and to potentially acquire additional mineral property assets. The fluctuations in commodity prices of base and precious metals has contributed to a challenging environment for mineral exploration and development, which has created opportunities as well as challenges for the potential acquisition of advanced mineral exploration projects or other related assets at potentially attractive terms.
In analyzing our activities, the most significant aspect relates to results of our exploration and potential development activities and those of our joint venture partners on a property-by-property basis. When our exploration or potential development activities, including drilling, sampling and geologic testing, indicate a project may not be economic or contain sufficient geologic or economic potential we may impair or completely write-off the property. Another significant factor in the success or failure of our activities is the price of commodities. For example, when the price of zinc is down, the value of zinc-bearing mineral properties decreases; however, when the price of zinc is up it may become more difficult and expensive to locate and acquire new zinc-bearing mineral properties with potential to have economic deposits.

The potential sale, joint venture or development of our mineral properties will occur, if at all, on an infrequent basis. Historically, we have recorded revenues and met our need for capital in the past through (i) the sale of properties and assets; (ii) joint venture payments, including delay rental payments; (iii) a royalty sale on our former Mt. Hamilton property; (iv) the sale of our shares of Vendetta and Kinross common stock; (v) long-term debt secured by our mineral property; (vi) short-term margin borrowing; and (vii) issuances of common stock. During 2019 we recorded mineral property income of $408,000 from the Royalty Sale, discussed above. During 2018 we recorded mineral property income from the sale of our Yanacocha Royalty of $502,000. In 2015 we recorded a gain on the sale of our interest in Mount Hamilton LLC of $12,309,000. During June 2012, we sold a royalty interest in our Mt. Hamilton project to Sandstorm Gold Ltd. for $10,000,000. Previous to the sale of our interest in Mt. Hamilton LLC, our last significant cash proceeds from a property or asset sale were recorded in 2000 upon the sale of our former Yanacocha property for $6,000,000.  Proceeds from the sale or joint venture of properties, although significant when they occur, have not been a consistent annual source of cash and would occur in the future, if at all, on an infrequent basis. We have reduced our exposure to the costs of our exploration activities in the past through the use of joint ventures. Although we anticipate the use of joint venture funding for some of our exploration activities will continue for the foreseeable future, we can provide no assurance that these or other sources of capital will be available in sufficient amounts to meet our needs, if at all.
(c). Results of Operations
Comparison of the year ended December 31, 2019 to the year ended December 31, 2018
We had a net loss of $3,289,000 or $0.06 per share for the year ended December 31, 2019 compared to a loss of $3,598,000 or $0.06 per basic and diluted share for the year ended December 31, 2018. As explained in more detail below, the primary reasons for the decrease in net loss during 2019 compared to 2018 was a decrease in (i) general and administrative expense to $1,368,000 during 2019 compared to general and administrative expense of $1,954,000 during 2018; (ii) an increase in interest income to $252,000 during 2019 compared to interest income of $192,000 during 2018 and (iii) a reduction in the unrealized loss on marketable equity securities to $711,000 during 2019 compared to a unrealized loss on marketable equity securities of $1,058,000 during 2018. Partially offsetting these factors that served contributed to the decrease in our net loss in 2019 were (i) a reduction in mineral property sale revenue to $408,000 from the Royalty Sale during 2019 compared to $502,000 from the sale of our Yanacocha Royalty during 2018; (ii) an increase in exploration expense to $1,807,000 during 2019 compared to exploration expense of $1,254,000 during 2018 and (iii) a loss on derivative instruments of $38,000 during 2019 with no similar item during 2018. Each of these items is discussed in greater detail below.
Our primary exploration activities during 2019 and 2018 were related to the Florida Canyon drilling program, started in 2018 and completed in 2019. Solitario agreed to pay a total of $1,580,000 toward a 39-hole 17,033- meter drilling program at Florida Canyon in three tranches based upon Nexa completing a fixed number of meters of drilling (the “Drilling Program”). During the fourth quarter of 2018, Nexa completed the first tranche of drilling, and Solitario recorded $527,000 of exploration expense related to the Drilling Program during 2018 accrued as accounts payable at December 31, 2018. This compared to exploration expense of $1,054,000 related to the Drilling Program during 2019 when Nexa completed the remaining drilling commitment. In addition, we incurred other exploration expenses at Florida Canyon of $18,000 and $24,000, respectively, during 2019 and 2018 not related to the Drilling Program. Nexa is evaluating the 2020 exploration program at Florida Canyon, however Solitario is not required to provide any of the exploration funding at Florida Canyon during 2020. Solitario incurred $199,000 of exploration expense during 2019 at its Lik project in Alaska as part of a 50/50 exploration program managed by its joint venture partner, Teck. This compares to exploration expense of $125,000 at the Lik project during 2018. During 2019, Teck completed extensive re-logging, re-mapping and related field work at Lik which resulted in the increased costs during 2019 compared to 2018. We are evaluating, along with Teck, a modest drilling program. The program, if approved, consists of drilling two or three core holes totaling approximately 1,000 meters. Drill targets under consideration include an area approximately one kilometer north of Lik and also below the Lik deposit to test for stacked mineralized horizons. Solitario would be responsible for 50% of the expenditures. During 2019 and 2018 we incurred exploration expense of $92,000 and $86,000, respectively, at our La Promesa project in Peru. These expenditures primarily related to community agreements and general exploration activities. We are planning a very limited exploration effort at La Promesa during 2020 and expect our related expenditures there will be lower during 2020 than in 2019. The remaining exploration expenditures during 2019 and 2018 related to reconnaissance work, including the evaluation of potential mineral properties for acquisition. We anticipate our 2020 reconnaissance exploration expenditures will be reduced from our 2019 expenditures. Our 2020 total exploration and development budget is approximately $976,000, which reflects the significant reduction in the expenditures at Florida Canyon, La Promesa and reconnaissance exploration, and the anticipated increase in exploration at our Lik project during 2020. Although we may acquire new mineral exploration properties during 2020, our 2020 exploration budget does not reflect any costs for projects we do not currently own. Our planned exploration activities in 2020 may be modified, as necessary for any drilling programs we may undertake, changes related to potential acquisition of new properties, joint venture funding, commodity prices and deployment of our capital.

We believe a discussion of our general and administrative costs should be viewed without the non-cash stock option compensation expense which is discussed below. Excluding these costs, general and administrative costs were $1,025,000 during 2019 compared to $1,294,000 during 2018. We reduced salary and benefits expense to $427,000 during 2019 compared to $619,000 during 2018 as a result of reductions in staff and salaries. In addition, (i) legal and accounting costs decreased to $185,000 during 2019 compared to $208,000 during 2018, primarily due to reduced activity; (ii) travel and investor relation costs decreased to $271,000 during 2019 compared to $308,000 during 2018 as a result of reductions in personnel and reduced market activities; (iii) we recorded directors and officer insurance expense of $53,000 during 2019 compared to $60,000 during 2018; and (iv) other costs related to office, insurance and miscellaneous costs decreased to $89,000 during 2019 compared to $99,000 during 2018. We anticipate general and administrative costs for 2020 will be similar to the costs incurred during 2019; however, this amount may vary significantly during 2020 depending on the outcome of our property evaluations and any strategic transactions we may attempt to execute upon. We have forecast 2020 general and administrative costs to be approximately $1,122,000, excluding non-cash stock option compensation expense.

We account for our employee stock options voluntarily surrenderedunder the provisions of Accounting Standards Codification No. 718 (“ASC No. 718”). We recognize stock option compensation expense on the date of grant for cancellation25% of the grant date fair value, and subsequently, based upon a straight-line amortization of the grant date fair value of each of its outstanding options. During the year ended December 31, 2019, we recorded $343,000 of non-cash stock option expense for the amortization of our outstanding options grant date fair value with a credit to additional paid-in-capital compared to $660,000 of non-cash stock option compensation expense during 2018. The amount was higher during 2018 primarily due to the amortization of 2,300,000 Conditional Options, which were approved on June 19, 2018 by our shareholders, and we recorded $422,000 of stock option compensation related to those options during 2018 for the vested portion of the grant date fair value of those options as of the date of approval. The majority of our remaining stock option compensation during 2019 and 2018 related to the normal vesting of other outstanding options. See Note 11, “Employee Stock Compensation Plans,” to our consolidated financial statements in Item 8, “Financial Statements and Supplementary Data to this Form 10-K” for an analysis of the changes in the fair value of our outstanding stock options and the components that are used to determine the fair value.
We recorded an unrealized loss on marketable equity securities of $711,000 during 2019 in the statement of operations compared to an unrealized loss on marketable equity securities of $1,058,000 recorded during 2018. The loss in both periods was primarily related to a decrease in the value of our holdings of 11,000,000 shares of Vendetta common stock, which decreased from a fair value of $2,192,000 at December 31, 2017 to a fair value of $1,249,000 at December 31, 2018, to a fair value of $424,000 at December 31, 2019, based on quoted market prices. In addition, we acquired an additional 3,450,000 common shares of Vendetta as part of the acquisition of certain Vendetta units in July of 2019, which decreased in the allocated fair value from the date of acquisition of $165,000 to a fair value of $133,000 on December 31, 2019, each unit consisting of one common share and one warrant to acquire one common share (the 2019 Vendetta Warrants). In addition, we recorded an unrealized gain on marketable equity securities of $150,000 during 2019 compared to an unrealized loss of $108,000 on our holdings of Kinross during 2018. We adopted ASU 2016-01 in the first quarter of 2018. We recorded a cumulative-effect adjustment for the change in accounting principle to accumulated deficit of $576,000 related to the adoption of ASU 2016-01. See Note 12, “Shareholders’ Equity” to the consolidated financial statements.
As of December 31, 2019, we had 14,450,000 shares of Vendetta common stock and 3,450,000 2019 Vendetta Warrants. We may sell some of our marketable equity securities from time to time during 2020 for working capital needs; however, we do not expect to sell all of our holdings of marketable equity securities during 2020. Any proceeds we may receive from sales of marketable equity securities during 2020 will be dependent on the quoted market price of the securities sold on the date of sale and may be at prices below the fair value at December 31, 2019. See “Liquidity and Capital Resources” below.
We recorded a loss on derivative instruments of $38,000 during 2019 primarily related to a loss on our 2019 Vendetta Warrants of $47,000 based upon a Black-Scholes model. This loss in value of the 2019 Vendetta Warrants was primarily related to a reduction in the price per share of Vendetta common stock, which was Cdn$0.09 per share when Solitario acquired the 2019 Vendetta Warrants and was Cdn$0.05 on December 31, 2019. Partially offsetting this decrease was a gain of $9,000 on certain Kinross covered call options previously grantedwe sold during the third quarter of 2019. We may continue to such personssell covered Kinross call options during 2019. There were no outstanding derivative instruments during 2018.
We recorded $25,000 of depreciation and amortization during 2019 compared to $25,000 of depreciation and amortization during 2018. The majority of our depreciation relates to depreciation on equipment acquired in 2017 as part of the acquisition at the Lik project. We amortize these assets over a five-year period. We anticipate our 2020 depreciation and amortization expense will be similar to our 2019 depreciation expense.
We recorded interest income of $252,000 during 2019 compared to interest income of $192,000 during 2018. The increase during 2019 was primarily related to an increase in the value of our mark-to-market investment in United States Treasury securities, which have a life of 30 days to 17 months, as a result of declining interest rates. The increase in interest income was partially mitigated by a reduction in our outstanding balance of United States Treasuries. We anticipate our interest income will decrease in 2020 compared to 2019 as a result of the use of our short-term investments and our cash balances for ordinary overhead, operational costs, and the exploration, evaluation and or acquisition of mineral properties discussed above. See “Liquidity and Capital Resources,” below, for further discussion of our cash and cash equivalent balances.
We recorded no deferred tax expense or benefit in either 2019 or 2018 as we provide a valuation allowance for the tax benefit arising out of our net operating losses for all periods presented. See Note 7, “Income Taxes” to our consolidated financial statements in Item 8, “Financial Statements and Supplementary Data” of this Form 10-K for additional discussion of our income tax valuation allowance, deferred tax assets and our net operating losses for 2019 and 2018. We anticipate we will continue to provide a valuation allowance for these net operating losses until we are in a net tax liability position with regards to those countries where we operate or until it is more likely than not that we will be able to realize those net operating losses in the future.
We regularly perform evaluations of our mineral property assets to assess the recoverability of our investments in these assets. All long-lived assets are reviewed for impairment whenever events or circumstances change which indicate the carrying amount of an asset may not be recoverable utilizing guidelines based upon future net cash flows from the asset as well as our estimates of the geologic potential of early stage mineral property and its related value for future sale, joint venture or development by us or others. We had no mineral property impairments during 2019 or 2018.

(d). Liquidity and Capital Resources
Cash
As of December 31, 2019, we had $574,000 in cash. We intend to utilize a portion of this cash and a portion of our short-term investments, discussed below, to fund our ordinary overhead, operational costs, exploration activities and the potential acquisition of mineral properties and other assets over the next several years. We may also use a portion of these assets to repurchase shares of our common stock, pursuant to the terms of a stock buy-back program discussed below.
Short-term Investments
As of December 31, 2019, we have $6,829,000 of our current assets in United States Treasury securities (“USTS”) with maturities of 30 days to 17 months. The USTS are recorded at their fair value, based upon quoted market prices. The USTS are highly liquid and may be sold in their entirety at any time at their quoted market price and are classified as a current asset. We anticipate we will roll over that portion of our USTS not used for operating costs or mineral property acquisitions as they mature during 2020.
Marketable Equity Securities
Our marketable equity securities are classified as available-for-sale and are carried at fair value, which is based upon market quotes of the underlying securities. We owned 100,000 shares of Kinross common stock at December 31, 2019. The Kinross shares are recorded at their fair value of $474,000 at December 31, 2019. As of December 31, 2019, we own 14,350,000 shares of Vendetta common stock recorded at their fair market value of $556,000 based upon quoted market prices. In addition, we own other marketable equity securities with a fair value of $9,000 as of December 31, 2019 based upon quoted market prices. Changes in the fair value of marketable equity securities are recorded as gains and losses in the statements of operations.
Working Capital
We had working capital of $8,487,000 at December 31, 2019 compared to working capital of $11,448,000 as of December 31, 2018. Our working capital at December 31, 2019 consists primarily of our cash and cash equivalents, our investment in USTS, discussed above, and our marketable equity securities, less our current liabilities of $269,000. As of December 31, 2019, our cash balances along with our short-term investments and marketable equity securities are adequate to fund our expected expenditures over the next year.
The nature of the mineral exploration business requires significant sources of capital to fund exploration, development and operation of mining projects. We expect we will need additional capital if we decide to develop or operate any of our current exploration projects or any projects or assets we may acquire. We anticipate we would finance any such development through the use of our cash reserves, short-term investments, joint ventures, issuance of debt or equity, or the sale of other exploration projects or assets.
Stock-Based Compensation Plans
At December 31, 2019, options to acquire 4,373,000 shares of our common stock were outstanding. There are 2,774,000 options that are vested and exercisable at December 31, 2019. At December 31, 2019, our outstanding options include 150,000 options granted during 2019 that are in the money with an exercise price of $0.28 per share, which is below the market price of a share of Solitario common stock at December 31, 2019 of $0.30 per share as quoted on the NYSE American exchange. See Note 11, “Employee Stock Compensation Plans” to our consolidated financial statements in Item 8, “Financial Statements and Supplementary Data of this Form 10-K for a discussion of the activity in our 2013 Plan during 2019 and 2018. We do not anticipate that stock option exercises will be a significant source of cash during 2020.

Share Repurchase Program
On October 28, 2015, our Board of Directors approved a share repurchase program that authorized us to purchase up to two million shares of our outstanding common stock. During 2019, our Board of Directors extended the term of the share repurchase program until December 31, 2020. All shares purchased to date have reduced the number of shares of outstanding common stock. The amount and timing of any shares purchased has been and will be determined by our management and the 2006 Plan,purchases will be effected in the open market or in privately negotiated transactions based upon market conditions and other factors, including Mr. Herald, Mr. Huntprice, regulatory requirements and Mr. Maronick.capital availability and in compliance with applicable state and federal securities laws. Purchases may also be made in accordance with Rule 10b-18 of the Exchange Act. The repurchase program does not require the purchase of any minimum number of shares of common stock by the Company, and may be suspended, modified or discontinued at any time without prior notice. No purchases have been or will be made outside of the United States, including on the TSX. Payments for shares of common stock repurchased under the program are being funded using the Company’s working capital. As of December 31, 2019, since the inception of the share repurchase program, we have purchased a total of 969,300 shares for an aggregate purchase price of $462,000 and these shares are no longer included in our issued and outstanding shares. We anticipate we will continue to purchase shares under the share repurchase plan during 2020 as determined by management.
Off-balance sheet arrangements
As of December 31, 2019, and 2018, we have no off-balance sheet arrangements.
(e). Cash Flows
Net cash used in operations during the year ended December 31, 2019 increased to $2,639,000 compared to $1,357,000 for the year ended December 31, 2018 primarily as a result of (i) the Drilling Program, which included the use of cash of $1,580,000, during 2019, as discussed above, compared to no use of cash for the Drilling Program during 2018, as the payment of $527,000 for the first tranche of drilling completed during 2018, was accrued as an accounts payable in 2018 and paid in 2019 and (ii) a reduction in mineral property revenue to $408,000 during 2019 for the Royalty Sale, of which $186,000 was received in cash, compared to the sale of our Yanacocha Royalty for cash of $502,000 during 2018. Partially offsetting this increased use of cash in operations was (i) a decrease in general and administrative expense, excluding non-cash stock option compensation to $1,025,000 during 2019 compared to $1,294,000 during 2018 and (ii) additional interest income of $252,000 during 2019 compared to $192,000 during 2018. These items are discussed in further detail above under “Results of Operations.”
Net cash provided by investing activities increased to $3,109,000 during 2019 compared to net cash provided of $1,361,000 during 2018. The primary source of cash was the sale of short-term investments of $3,338,000 during 2019 compared to $1,371,000 during 2018. During 2019 we used $233,000 to purchase of Vendetta units. There were no other significant provisions or uses of cash during 2019 or 2018. We anticipate we will continue to utilize proceeds from the sale of our short-term investments to fund our operations during 2020.
The net cash used in financing activities of $13,000 during 2019 and $101,000 during 2018 were for the repurchase of common stock for cancellation, discussed above. We anticipate we will use a limited amount of cash approximating expenditures during each of the past two years for the repurchase of shares during 2020.
(f). Development Activities, Exploration Activities, Environmental Compliance and Contractual Obligations
Development Activities
We do not have any ongoing mineral development activities, which are activities for the development of mineral properties with reserves for potential mining.
Exploration Activities
A historically significant part of our business involves the review of potential property acquisitions and continuing review and analysis of properties in which we have an interest, to determine the exploration and development potential of the properties. In analyzing expected levels of expenditures for work commitments and property payments, our obligations to make such payments fluctuate greatly depending on whether, among other things, we make a decision to sell a property interest, convey a property interest to a joint venture, or allow our interest in a property to lapse by not making the work commitment or payment required. In acquiring many of our interests in mining claims and leases, we have entered into agreements, which generally may be canceled at our option. We are often required to make minimum rental and option payments in order to maintain our interest in certain claims and leases. Our net 2019 mineral and surface property rental and option payments, included in exploration expense, were $13,000. Our 2020 total exploration property rentals and option payments for properties we own, have under joint venture, or operate are estimated to be approximately $859,000. Assuming that our joint ventures continue in their current status and that we do not appreciably change our property positions on existing properties, we estimate that our joint venture partners will pay on our behalf or reimburse us approximately $816,000 of these annual payments. These obligations are detailed below under “Contractual Obligations.” In addition, we may be required to make further payments in the future if we elect to exercise our options under those agreements or if we enter into new agreements.

Environmental Compliance
We are subject to various federal, state and local environmental laws and regulations in the countries where we operate. We are required to obtain permits in advance of initiating certain of our exploration activities, to monitor and report on certain activities to appropriate authorities, and to perform remediation of environmental disturbance as a result of certain of our activities. Historically, the nature of our activities of review, acquisition and exploration of properties prior to the establishment of reserves, which may include mapping, sampling, geochemistry and geophysical studies, as well as some limited exploration drilling, has not resulted in significant environmental impacts in the past. We have historically carried on our required environmental remediation expenditures and activities, if any, concurrently with our exploration activities and expenditures. The expenditures to comply with our environmental obligations are included in our exploration expenditures in the statement of operations and have not been material to our capital or exploration expenditures and have not had a material effect on our financial position. For the years ended December 31, 2019 and 2018, we have not capitalized any costs related to environmental control facilities. We do not anticipate our exploration activities will result in any material new or additional environmental expenditures or liabilities in the near future.

(g). Exploration Joint Ventures, Royalty and Other Properties
The following discussion relates to an analysis of our anticipated property exploration plans as of December 31, 2019. Please also see Note 2, “Mineral Properties,” to the consolidated financial statements in Item 8, “Financial Statements and Supplementary Data,” and our discussion of our properties under Item 2, “Properties” of this Annual Report on Form 10-K for a more complete discussion of all of our mineral properties.
Florida Canyon
The Florida Canyon project is an advanced-stage high-grade zinc project in Peru. Based on extensive exploration and development work conducted to date, we believe the property has potential to be developed into a mine over the next several years. The project is held in a joint venture between Nexa (61%) and Solitario cancelled(39%).
Solitario and Nexa jointly completed a PEA in 2017 that incorporated a variety of Nexa-generated prefeasibility studies into the analysis. The PEA evaluation included resource estimation, mining and processing recovery estimates, a preliminary mining and processing plan, infrastructure layout, environmental considerations and an economic analysis based on certain base case parameters. The PEA envisioned an underground mining operation with a 2,500 tonne per day floatation mill for processing, resulting in a 12.5-year mine life. Concentrates would be trucked to Nexa’s Cajamarquilla zinc smelter facility in Lima, Peru.
The terrain at Florida Canyon is steep and previous project access supporting surface and underground work programs was conducted by helicopter. The lack of road access restricted the scope of field activities to further advance the project. During 2019 limited work was undertaken on road access to the project, and Nexa expects to continue to work on completing the road access during 2020. During 2019, Nexa completed the Drilling Program and several significant drill intercepts were encountered. Solitario reported the results of the drill intercepts during 2019. Nexa is evaluating the results of the Drilling Program and Solitario anticipates Nexa will continue the exploration of Florida Canyon during 2020. Should Nexa complete the road, heavy equipment will be able to enter the project area and allow feasibility related activities to proceed more efficiently. Important future activities that may be facilitated by the completion of the road are the construction of an underground tunnel into the Karen-Milagros high-grade zinc zone, detailed underground resource/reserve definition drilling, surface drilling designed to increase the project resources and additional feasibility-related studies.
Solitario’s payments of $1,580,000 related to the Drilling Program are in the form of an advance on Solitario’s commitment to fund 30% of any future development of Florida Canyon under the original joint venture agreement between Solitario and Nexa. Accordingly, in the event Florida Canyon is developed, which cannot be assured at this time, the funds paid to Nexa related to the Drilling Program, will reduce the amount of Solitario’s obligation to fund 30% of future development costs, and / or repay any loans from Nexa for future development costs at Florida Canyon.

Lik project
The Lik project is an advanced-staged high-grade zinc project. The project is held in a joint venture between Teck (50%) and Solitario (50%).
Zazu completed a PEA in 2014 that incorporated a variety of prefeasibility studies into the analysis. These studies included resource estimation, mining and processing recovery estimates, a preliminary mining and processing plan, infrastructure layout, environmental considerations and an economic analysis based on the base case parameters. The PEA envisioned an open pit mining operation with a 5,500 ton per day floatation mill for processing resulting in a nine-year mine life. Concentrates would be handled through the DMTS road and port system that currently handles all concentrate produced by the nearby Red Dog zinc mine of Teck. The PEA analyzed the Lik project as a stand-alone operation building its own independent processing, tailings and port facilities.
During 2019 Solitario and Teck jointly funded a gravity geophysical program, geologic mapping, geochemical sampling, an evaluation of past baseline environmental work for mine permitting previously initiated by Zazu, and rehabilitation work at the Lik camp. Based on this work, Teck and Solitario are evaluating a modest drilling program at Lik for 2020. The program, if approved, consists of drilling two or three core holes totaling approximately 1,000 meters. Drill targets under consideration include an area approximately one kilometer north of Lik and also below the Lik deposit to test for stacked mineralized horizons. It is anticipated Teck will manage the 2020 exploration program as the designated operator during 2020, although Solitario will remain the operator of the joint venture in subsequent years.
Other Properties
Our 2020 total exploration and development budget is approximately $976,000 for exploration and evaluation of the Lik project as well as our La Promesa project and evaluation of potential new acquisitions of properties primarily in Peru and in other regions of North and South America. We expect to carry out our exploration activities during 2020 utilizing Teck at Lik and our own employees and contract geologists on our other projects.
 (h). Discontinued Projects
We had no mineral property impairments during 2019 or 2018. We did sell certain royalty properties in the Royalty Sale during 2019, discussed above under “Recent Developments.”

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors
Solitario Zinc Corp.
Wheat Ridge, Colorado
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Solitario Zinc Corp. (the “Company”) as of December 31, 2019 and 2018, the related consolidated statements of operations, shareholders' equity, and cash flows for each of the years in the two-year period ended December 31, 2019, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
The Company's management is responsible for these financial statements. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
We have served as the Company’s auditor since 2005.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
For the years ended December 31, 2019 and 2018
1. Business and Summary of Significant Accounting Policies
Business and company formation
Solitario Zinc Corp. (“Solitario,” or the “Company”) is an exploration stage company as defined in Industry Guide 7, as issued by the United States Securities and Exchange Commission (“SEC”). Solitario was incorporated in the state of Colorado on November 15, 1984 as a wholly owned subsidiary of Crown Resources Corporation ("Crown"). In July 1994, Solitario became a publicly traded company on the Toronto Stock Exchange (the "TSX") through its initial public offering. Solitario has been actively involved in mineral exploration since 1993. Solitario’s primary business is to acquire exploration mineral properties and/or discover economic deposits on its mineral properties and advance these deposits, either on its own or through joint ventures, up to the development stage. At that point, or sometime prior to that point, Solitario would likely attempt to sell its mineral properties, pursue their development either on its own, or through a joint venture with a partner that has expertise in mining operations, or create a royalty with a third party that continues to advance the property. Solitario is primarily focused on the acquisition and exploration of zinc-related exploration mineral properties. In addition to focusing on its mineral exploration properties and the evaluation of mineral properties for acquisition. Solitario also evaluates potential strategic corporate transactions as a means to acquire an interest in new precious and base metal properties and assets with exploration potential as well as other potential corporate transactions and business combinations that Solitario determines to be favorable to Solitario.
Solitario has recorded revenue in the past from the sale of mineral properties, including the sale of certain mineral royalty properties in January 2019, discussed below, and the sale in June 2018 of its interest in the royalty on the Yanacocha property. Revenues and / or proceeds from the sale or joint venture of properties or assets have not been a consistent annual source of cash and would only occur in the future, if at all, on an infrequent basis.
Solitario currently considers its carried interest in the Florida Canyon project and its interest in the Lik project to be its core mineral property assets. Nexa Resources, Ltd. (“Nexa”), Solitario’s joint venture partner, is continuing the exploration and furtherance of the Florida Canyon project and Solitario is monitoring progress at Florida Canyon. Solitario is working with its 50% joint venture partner, Teck American Incorporated, a wholly owned subsidiary of Teck Resources Limited (both companies are referred to as “Teck”), in the Lik deposit to further the exploration of the Lik project, and to evaluate potential development plans for the Lik project.
As of December 31, 2019 and 2018, Solitario has significant balances of cash and short-term investments that Solitario anticipates using, in part, to further the development of the Florida Canyon project and the Lik project and to potentially acquire additional mineral property assets. The fluctuations in precious metal and other commodity prices has contributed to a challenging environment for mineral exploration and development, which has created opportunities as well as challenges for the potential acquisition of early-stage and advanced mineral exploration projects or other related assets at potentially attractive terms.
Recent Developments
On January 22, 2019, Solitario completed the sale of its interest in certain royalties to SilverStream SEZC, a private Cayman Island royalty and streaming company (“SilverStream”) for Cdn$600,000 (the “Royalty Sale”). The Royalty Sale covered (i) a royalty on the formerly Solitario-owned 125,000-acre polymetallic Pedra Branca palladium, platinum, gold, nickel, cobalt and chrome project in Brazil, (ii) a royalty covering 3,880 acres of non-producing exploration properties in Mexico, and (iii) a purchase option on royalties covering 11 separate non-producing properties covering over 16,500 acres in Montana. At closing of the Royalty Sale, Solitario received Cdn$250,000 in cash and a convertible note from SilverStream in the principal amount of Cdn$350,000 (the “SilverStream Note”). The SilverStream Note was originally due December 31, 2019, accrued 5% per annum simple interest, payable on a quarterly basis, and is convertible into common shares of SilverStream, at the discretion of SilverStream, by providing Solitario a notice of conversion. In December of 2019, Solitario and SilverStream agreed to extend the due date of the SilverStream Note to June 30, 2020, and to increase the interest rate to 8% per annum simple interest. All other terms of the SilverStream Note remained the same. SilverStream may only provide a notice of conversion if SilverStream has completed an initial public offering during the term of the SilverStream Note for minimum proceeds of Cdn$5,000,000, otherwise the SilverStream Note will be payable in cash at the maturity date. Pursuant to the terms of the SilverStream Note, if SilverStream were to complete an initial public offering and the SilverStream Note was converted, Solitario would receive common shares converted at 85% of the weighted average quoted price of a share of SilverStream common stock for the most recent 10-day period prior to the notice of conversion. During 2019, Solitario recorded mineral property revenue of $408,000 for the Royalty Sale, consisting of the fair value of the cash received on the date of the sale of $185,000 and the fair value of the SilverStream Note on the date of the sale of $263,000 less the carrying value of the royalties sold of $40,000. Solitario recorded interest income of $12,000 from the SilverStream Note during 2019. As of December 31, 2019, the SilverStream Note was recorded at $268,000, based upon the current US dollar / Canadian dollar exchange rate, and Solitario recorded a credit to exchange gain of $5,000, included in general and administrative expense during 2019.

Financial reporting
The consolidated financial statements include the accounts of Solitario and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("generally accepted accounting principles") and are expressed in US dollars.
Revenue recognition
Solitario has recorded revenue from the sale of exploration mineral properties and joint venture property payments. Solitario’s policy is to recognize revenue from the sale of its exploration mineral properties (those without reserves) on a property by property basis, computed as the cash received and / or collectable receivables less any capitalized cost. Payments received for the sale of exploration property interests that are less than the properties cost are recorded as a reduction of the related property's capitalized cost. In addition, Solitario’s policy is to recognize revenue on any receipts of joint venture property payments in excess of its capitalized costs on a property that Solitario may lease to another mining company.
Solitario has recognized revenue during 2019 of $408,000 related to the Royalty Sale, discussed above, and of $502,000 during 2018 from the sale of its former Yanacocha exploration mineral property. Solitario expects any property sales in the future to be on an infrequent basis. Prior to the Yanacocha sale, the last proceeds from joint venture property payments was in 2015 and Solitario does not expect to record joint venture property payments on any of its currently held properties for the foreseeable future. Historically, Solitario’s revenues have been infrequent and significant individual transactions and have only been from sales to well known or vetted mining companies. Solitario has never had a return on any of its sales recorded as revenue in its history and does not anticipate it will recognize any estimated returns on its current or future recorded revenues.
Use of estimates
The preparation of financial statements in conformity with generally accepted accounting principles 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Some of the more significant estimates included in the preparation of Solitario's financial statements pertain to: (i) the recoverability of mineral properties related to its mineral exploration properties and their future exploration potential; (ii) the fair value of stock option grants to employees; (iii) the ability of Solitario to realize its deferred tax assets; (iv) Solitario's investment in marketable equity securities; and (v) the collectability of the SilverStream Note.
In performing its activities, Solitario has incurred certain costs for mineral properties. The recovery of these costs is ultimately dependent upon the sale of mineral property interests or the development of economically recoverable ore reserves and the ability of Solitario to obtain the necessary permits and financing to successfully place the properties into production, and upon future profitable operations, none of which is assured.
Cash and cash equivalents
Cash equivalents include investments in highly liquid money-market securities with original maturities of three months or less when purchased. At December 31, 2019, approximately $554,000 of Solitario’s cash and cash equivalents are held in brokerage accounts and foreign banks, which are not covered under the Federal Deposit Insurance Corporation (“FDIC”) rules for the United States.
Short-term investments
At December 31, 2019, Solitario has United States Treasury securities (“USTS”) with maturities of 30 days to 17 months recorded at their fair value of $6,829,000. Solitario’s short-term investments are recorded at their fair value, based upon quoted market prices. The short-term investments are highly liquid and may be sold in their entirety at any time at their quoted market price and are classified as a current asset.

 Mineral properties
Solitario expenses all exploration costs incurred on its mineral properties prior to the establishment of proven and probable reserves through the completion of a feasibility study. Initial acquisition costs of its mineral properties are capitalized. Solitario regularly performs evaluations of its investment in mineral properties to assess the recoverability and/or the residual value of its investments in these assets. All long-lived assets are reviewed for impairment whenever events or circumstances change which indicate the carrying amount of an asset may not be recoverable, utilizing established guidelines based upon undiscounted future net cash flows from the asset or upon the determination that certain exploration properties do not have sufficient potential for economic mineralization.
Derivative instruments
Solitario accounts for its derivative instruments in accordance with ASC 815, "Accounting for Derivative Instruments and Hedging Activities" (“ASC 815”).  During 2016, Solitario acquired its initial investment in Vendetta Mining Corp. (“Vendetta”) units, including the 2016 Vendetta Warrants (defined below). During 2017, Solitario exercised all of the 2016 Vendetta Warrants. During 2019, Solitario acquired additional Vendetta units, which included 2019 Vendetta Warrants (defined below). Changes in fair value of the 2019 Vendetta Warrants are recognized in the statements of operations in the period of change as gain or loss on derivative instruments. Solitario has entered into covered calls from time to time on its investment in Kinross marketable equity securities. Solitario has not designated its covered calls as hedging instruments and any changes in the fair value of the covered calls and its warrants are recognized in the statements of operations in the period of the change as gain or loss on derivative instruments.
Fair value
Financial Accounting Standards Board ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”) establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. For certain of Solitario's financial instruments, including cash and cash equivalents accounts payable and the SilverStream Note, the carrying amounts approximate fair value due to their short-term maturities. Solitario's short-term investments in USTS, its marketable equity securities and any covered call options against those marketable equity securities are carried at their estimated fair value based on quoted market prices. See Note 9, “Fair Value of Financial Instruments,” below.
Marketable equity securities
Solitario's investments in marketable equity securities are classified as available-for-sale and are carried at fair value, which is based upon surrender.quoted prices of the securities owned. Solitario records investments in marketable equity securities as available-for-sale for investments in publicly traded marketable equity securities for which it does not exercise significant control and where Solitario has no representation on the board of directors of those companies and exercises no control over the management of those companies. The cost of marketable equity securities sold is determined by the specific identification method. Changes in fair value are recorded as unrealized gain or loss in the consolidated statement of operations.
Foreign exchange
The United States dollar is the functional currency for all of Solitario's foreign subsidiaries. Although Solitario's South American exploration activities during 2019 and 2018 were conducted primarily in Peru, a portion of the payments for the land, leasehold and exploration agreements as well as certain exploration activities are denominated in United States dollars. Foreign currency gains and losses are included in the results of operations in the period in which they occur.
Income taxes
Solitario accounts for income taxes in accordance with ASC 740, “Accounting for Income Taxes” (“ASC 740”). Under ASC 740, income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due plus deferred taxes related to certain income and expenses recognized in different periods for financial and income tax reporting purposes. Deferred tax assets and liabilities represent the future tax return consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred taxes are also recognized for operating losses and tax credits that are available to offset future taxable income and income taxes, respectively. A valuation allowance is provided if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Accounting for uncertainty in income taxes
ASC 740 clarifies the accounting for uncertainty in income taxes recognized in a company's financial statements. ASC 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. ASC 740 provides that a company's tax position will be considered settled if the taxing authority has completed its examination, the company does not plan to appeal, and it is remote that the taxing authority would reexamine the tax position in the future. These provisions of ASC 740 had no effect on Solitario's financial position or results of operations. See Note 7, “Income Taxes,” below.
Earnings per share
The calculation of basic and diluted earnings (loss) per share is based on the weighted average number of shares of common stock outstanding during the years ended December 31, 2019 and 2018. Potentially dilutive shares, consisting of outstanding common stock options for 4,373,000 and 5,223,160, respectively, Solitario common shares were excluded from the calculation of diluted earnings (loss) per share for the year ended December 31, 2019 and 2018 because the effects were anti-dilutive.
Employee stock compensation and incentive plans
Solitario classifies all of its stock options as equity options in accordance with the provisions of ASC 718, “Compensation – Stock Compensation.” See Note 11, “Employee Stock Compensation Plans,” below.
Recently adopted accounting pronouncements
On January 1, 2019, Solitario adopted Accounting Standards Update No. 2016-02 Leases (“ASU 2016-02”) which requires the application of ASC 842 and the recognition of right-of-use assets and related liabilities associated with all leases that are not short-term in nature. As a result of the adoption of ASU 2016-02, Solitario recorded both an operating lease asset for its Wheat Ridge, Colorado office of $82,000 and an operating lease liability of $82,000 related to the same lease. The adoption of ASU 2016-02 did not require the recording of any other assets or liabilities on our condensed consolidated balance sheets and had an immaterial effect on Solitario’s consolidated statement of operations for 2019 and its consolidated statement of cash flows for 2019. Solitario has elected the practical expedient option to use January 1, 2019, the effective date of adoption, as the initial date of transition and not to restate comparative prior periods and to carry forward historical lease classification. See Note 4, “Operating Leases” for more information and disclosures regarding Solitario’s leases.
Recently issued accounting pronouncements
In 2018, the SEC adopted amendments to the disclosure requirements for mining registrants. Under these new rules, SEC Industry Guide 7 will be rescinded and replaced with the disclosure standards under new Regulation S-K Subpart 1300. SEC Industry Guide 7 remains in effect, subject to a transition period. Solitario will be required to comply with the new rules for fiscal years 2021 and after. Accordingly, future adjustment to estimates of mineralized material will occur due to the differing standards under the new requirements including, but not limited to, the replacement of any estimate of mineralized material with an estimate of “mineral resources.”
The FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurements of Credit Losses on Financial Statements (“ASU No. 2016-13”). Among other things, these amendments require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. ASU No. 2016-13 is effective for Solitario for fiscal year, and interim periods within those fiscal years, beginning after December 15, 2019. Solitario does not expect the adoption of ASU No. 2016-13 to have a material impact on its consolidated financial position or results of operations.

Exploration property
Solitario's exploration mineral properties at December 31, 2019 and 2018 consist of use rights related to its exploration properties, and the value of such assets is primarily driven by the nature and amount of economic mineral ore believed to be contained, or potentially contained, in such properties. The amounts capitalized as mineral properties include concession and lease or option acquisition costs. Capitalized costs related to a mineral property represent its fair value at the time it was acquired. At December 31, 2019, none of Solitario’s exploration properties have production (are operating) or contain proven or probable reserves. Solitario's exploration mineral properties represent interests in properties that Solitario believes have exploration and development potential. Solitario's mineral use rights generally are enforceable regardless of whether proven and probable reserves have been established.
In addition to its capitalized exploration properties, Solitario has an interest in its Florida Canyon exploration concessions, which are currently subject to a joint venture agreement where joint venture partners made stand-by joint venture payments to Solitario prior to January 1, 2015. Solitario recorded joint venture property payment revenue received in excess of capitalized costs. Per the joint venture agreement, as of December 31, 2019, no further standby joint-venture payments are due to Solitario on the Florida Canyon project. At December 31, 2019 and 2018, Solitario has no remaining capitalized costs related to its Florida Canyon joint venture.
On January 22, 2019, Solitario completed the Royalty Sale, discussed above under “Recent Developments” to SilverStream for Cdn$600,000. At closing of the Royalty Sale, Solitario received Cdn$250,000 in cash and the SilverStream Note with a principal amount of Cdn$350,000, and a maturity date of December 31, 2019, which was subsequently extended to June 30, 2020. During the nine months ended September 30, 2019, Solitario recorded mineral property revenue of $408,000 from the Royalty Sale, consisting of the fair value of the cash received on the date of the sale of $185,000 and the fair value of the SilverStream Note on the date of the sale of $263,000, less the carrying value of the royalties sold of $40,000.
On April 26, 2018, Solitario sold the Yanacocha Royalty to Newmont for $502,000 in cash. Newmont owns the underlying mineral concessions covered by the Yanacocha Royalty. None of the concessions covered by the Yanacocha Royalty have any reported reserves or resources. Solitario had no mineral property capitalized cost in the Yanacocha Royalty and recorded Mineral Property Revenue of $502,000 during 2018.
Discontinued projects
Solitario did not abandon or impair any of its properties during 2019 or 2018 and did not record any mineral property write-downs during the years ended December 31, 2019 or 2018.

Asset Retirement Obligation
In connection with the acquisition of Zazu, Solitario recorded an asset retirement obligation of $125,000 for Solitario’s estimated reclamation cost of the existing disturbance at the Lik project. This disturbance consists of an exploration camp including certain drill sites and access roads at the camp. The estimate was based upon estimated cash costs for reclamation as determined by the permitting bond required by the State of Alaska, for which Solitario has retained a reclamation bond insurance policy in the event Solitario or its 50% partner, Teck, do not complete required reclamation.
Solitario has not applied a discount rate to the recorded asset retirement obligation as the estimated time frame for reclamation is not currently known, as reclamation is not expected to occur until the end of the Lik project life, which would follow future development and operations, the start of which cannot be estimated or assured at this time. Additionally, no depreciation will be recorded on the related asset for the asset retirement obligation until the Lik project goes into operation, which cannot be assured.
3. Marketable Equity Securities
On May 2, 2016, Solitario purchased 7,240,000 units of Vendetta for aggregate consideration of $289,000. Each unit included one common share of Vendetta and one warrant which allow the holder to purchase one share of Vendetta common stock at a price of Cdn$0.10 per share for a period of two years (the “2016 Vendetta Warrants”). The purchase price of the units of $289,000 was allocated between the Vendetta common shares and the 2016 Vendetta Warrants based upon total fair values on the date of purchase. The Vendetta common stock was allocated a purchase cost of $186,000 and the 2016 Vendetta Warrants were allocated a purchase cost of $103,000. During 2017 Solitario exercised all of its 2016 Vendetta Warrants and sold 3,480,000 shares of Vendetta common stock.
On July 31, 2019, Solitario purchased 3,450,000 Vendetta units for aggregate consideration of $233,000. Each unit consisted of one share of Vendetta common stock and one warrant which allows the holder to purchase one additional share of Vendetta common stock at a purchase price of Cdn$0.13 per share for a period of three years (the “2019 Vendetta Warrants”). The purchase of the units on July 31, 2019 increased Solitario’s holdings of Vendetta common shares to 14,450,000 shares. On the purchase date Solitario recorded marketable equity securities of $165,000 for the Vendetta shares acquired and $68,000 for the 2019 Vendetta Warrants based upon an allocation of the purchase price of the Vendetta units, based upon (i) the fair value of the Vendetta common shares received, based upon the quoted market price for Vendetta common shares and (ii) the fair value of 2019 Vendetta Warrants based upon a Black Scholes model, using the stock price of Cdn$0.09, volatility of 79%, a term of three years and a discount rate of 1.5%. During 2019, Solitario charged loss on derivative instruments $47,000 for the change in the value of the 2019 Vendetta Warrants.
As of December 31, 2019, Solitario owned 14,500,000 shares of Vendetta common stock which are carried at their fair value based upon the quoted market price of Vendetta, whose common shares are listed on the TSX venture exchange, and included in marketable equity securities.
The following tables summarize Solitario’s marketable equity securities and adjustments to fair value:

 $1,585 

During 2019 Solitario added 3,450,000 shares of Vendetta through the purchase of the Vendetta units, discussed above, and recorded an increase in marketable equity securities of $165,000. Solitario did not acquire any marketable equity securities during 2018. Solitairo did not sell any marketable equity securities during 2019 or 2018. Solitario recorded a loss on marketable equity securities of $711,000 and $1,058,000, respectively, during 2019 and 2018 for the change in the fair value of its marketable equity securities.
4. Operating Lease
Solitario adopted ASU 2016-02 effective January 1, 2019 and accounts for its leases in accordance with ASC 842. Solitario leases one facility, its Wheat Ridge, Colorado administrative office (the “WR Lease”), that has a term of more than one year. Solitario has no other material operating lease costs. The WR Lease is classified as an operating lease and has a term of 14 months at December 31, 2019, with no renewal option. At December 31, 2019, the right-of-use office lease asset for the WR Lease is classified as other assets and the related liability separated between current and non-current office lease liabilities in the consolidated balance sheet. Lease expense is recognized on a straight-line basis over the lease term, with variable lease payments recognized in the period those payments are incurred. During 2019, Solitario recognized $40,000 of non-cash lease expense for the WR Lease included in general and administrative expense. Cash lease payments of $37,000 were made on the WR Lease during 2019 and this amount, less $3,000 of imputed interest during 2019, reduced the related liability on the WR Lease. The discount rate within the WR Lease is not determinable and Solitario applied a discount rate of 5% based upon Solitario’s estimate of its cost of capital in recording the WR Lease.

6. Revenue mineral property sale
On January 22, 2019, Solitario completed the sale of its interest in certain royalties to SilverStream, discussed above and recorded mineral property revenue of $408,000 for the Royalty Sale, consisting of the fair value of the cash received on the date of the sale of $185,000 and the fair value of the SilverStream Note on the date of the sale of $263,000 less the carrying value of the royalties sold of $40,000.
At closing of the Royalty Sale, Solitario received Cdn$250,000 in cash and the SilverStream Note in the principal amount of Cdn$350,000. As of December 31, 2019, the SilverStream Note is due June 30, 2020 and accrues interest at 8% per annum simple interest. Solitario recorded interest income of $12,000 from the SilverStream Note during 2019. As of December 31, 2019, the SilverStream Note was recorded at $268,000, based upon the current US dollar / Canadian dollar exchange rate, and Solitario recorded a credit to exchange gain of $5,000 related to the SilverStream Note, included in general and administrative expense during 2019.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of foreign earnings.
While the Tax Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions, the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) provisions. The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. The Company currently has no profitable foreign subsidiaries. Therefore, this provision currently has no impact on the Company.
The BEAT provisions in the Tax Act eliminates the deduction of certain base-erosion payments made to related foreign corporations and impose a minimum tax if greater than regular tax. The Company does not expect it will be subject to this tax and therefore has not included any tax impacts of BEAT in its consolidated financial statements for the years ended December 31, 2019 and 2018.
As a result of the ownership change resulting from Solitario’s acquisition of Zazu Metals (Alaska) Corp, utilization of its United States Federal and State of Alaska net operating losses will be limited due to the annual limitation provided by Section 382 of the Internal Revenue Code.
During 2019, the valuation allowance increased primarily due to the addition of deferred tax assets related to current year net operating losses. During 2018, the valuation allowance decreased primarily due to the adjustments to deferred taxes that were part of the Zazu acquisition and the disposition of royalties that were part of the Yanacocha sale.
At December 31, 2019, Solitario has unused US Federal Net Operating Loss carryovers of $17,576,000 and unused US State Net Operating Loss carryovers of $18,174,000 which begin expiring in 2027. As a result of the ownership change of Zazu Metals (Alaska) Corp, utilization of some of these federal and state losses will be limited due to the annual limitation provided by Section 382 of the Internal Revenue Code. Solitario has unused Capital Loss carryovers of $10,416,000 for US Federal and US State purposes which begin expiring in 2020. Solitario has Canadian loss carryforwards of $9,611,000 which begin expiring in 2027. Other foreign loss carryforwards for which Solitario has provided a full valuation allowance related to Solitario’s exploration activities in Peru. The Peru losses do not expire.
Solitario adopted ASC 740, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 requires that Solitario recognize in its consolidated financial statements, only those tax positions that are “more-likely-than-not” of being sustained as of the adoption date, based on the technical merits of the position. As a result of the implementation of ASC 740, Solitario performed a comprehensive review of its material tax positions in accordance with recognition and measurement standards established by ASC 740. The provisions of ASC 740 had no effect on Solitario’s financial position, cash flows or results of operations at December 31, 2019 or December 31, 2018, or for the years then ended as Solitario had no unrecognized tax benefits.
Solitario and its subsidiaries are subject to the following material taxing jurisdictions: United States Federal, State of Colorado, State of Alaska, Canada and Peru. Solitario’s United States federal, Canada and State of Alaska returns for years 2017 and forward and Solitario’s Peru and State of Colorado returns for tax years 2015 and forward are subject to examination. Solitario’s policy is to recognize interest and penalties related to uncertain tax benefits in income tax expense. Solitario has no accrued interest or penalties related to uncertain tax positions as of December 31, 2019, or December 31, 2018 or for the years then ended.
8. Derivative Instruments:
Covered call options
From time to time Solitario has sold covered call options against its holdings of Kinross. The business purpose of selling covered calls is to provide additional income on a limited portion of shares of Kinross that Solitario may sell in the near term, which is generally defined as less than one year and any changes in the fair value of its covered calls are recognized in the statement of operations in the period of the change. During 2019 Solitario sold covered calls against its holdings of Kinross for $9,000 in cash, all of which expired unexercised during 2019. As of December 31, 2019, there were no remaining liabilities related to call options.
Vendetta Warrants
At December 31, 2019 Solitario held 2019 Vendetta Warrants which give Solitario the right to purchase 3,450,000 Vendetta common shares for Cdn$0.13 per share through July 31, 2022. At December 31, 2019, Solitario recorded 2019 Vendetta Warrants at their fair value of $21,000 based upon a Black Scholes model with a stock price of Cdn$0.05, a term of 2.6 years, a volatility of 65%, and an interest rate of 1.6%. Solitario recorded a loss on derivative instruments related to the 2019 Vendetta Warrants of $47,000 during 2019.

9. Fair Value of Financial Instruments:
For certain of Solitario's financial instruments, including cash and cash equivalents, the SilverStream Note, payables and short-term debt, the carrying amounts approximate fair value due to their short maturities. Solitario's marketable equity securities, including its investment in shares of Kinross common stock, Vendetta common stock and TNR Gold Corp (“TNR”) common stock, are carried at their estimated fair value based on publicly available quoted market prices.
Solitario applies ASC 820 that establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. ASC 820 also requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy for which these assets and liabilities must be grouped, based on significant levels of inputs as follows:
Level 1: Quoted prices in active markets for identical assets or liabilities;
Level 2: Quoted prices in active markets for similar assets and liabilities and inputs that are observable for the asset or liability; or
Level 3: Unobservable inputs in which there is little or no outstanding optionsmarket data, which require the reporting entity to develop its own assumptions.
The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement. During the years ended December 31, 2019 and 2018, there were no reclassifications in financial assets or liabilities between Level 1, 2 or 3 categories.
The following is a listing of Solitario’s financial assets and liabilities required to be measured at fair value on a recurring basis and where they are classified within the hierarchy as of December 31, 2019:

Items measured at fair value on a recurring basis:
Short-term investments: At December 31, 2019 and 2018, Solitario’s holdings of short-term investments consist of USTS recorded at their fair value based upon quoted market prices.
Marketable equity securities: At December 31, 2019 and 2018, the fair value of Solitario’s holdings in shares of Vendetta, Kinross, and TNR marketable equity securities are based upon quoted market prices.
2019 Vendetta Warrants: At December 31, 2019 the fair value of Solitario’s 2019 Vendetta Warrants is based upon a Black Scholes model, using market inputs.
During the year ended December 31, 2019, Solitario did not change any of the valuation techniques used to measure its financial assets and liabilities at fair value.
10. Commitments and Contingencies:
In acquiring its interests in mineral claims and leases, Solitario has entered into lease agreements, which may be canceled at its option without penalty. Solitario is required to make minimum rental and option payments in order to maintain its interests in certain claims and leases. See Note 2, “Mineral Properties,” above. Solitario estimates its 2020 property rentals and option payments for properties Solitario owns, has under eitherjoint venture or Solitario operates to be approximately $859,000. Assuming that Solitario’s joint ventures continue in their current status and that Solitario does not appreciably change its property positions on existing properties, approximately $816,000 of these annual payments are paid or are reimbursable to us by Solitario’s joint venture partners. Solitario may be required to make further payments in the 2006future if it acquires new properties or enters into new agreements.
Solitario has recorded an asset retirement obligation of $125,000 related to its Lik project in Alaska. See Note 2, “Mineral Properties,” above.
Solitario leases office space under a non-cancelable operating lease for the Wheat Ridge, Colorado office which provides for total minimum annual rent payments of $43,000 through March of 2021.
11. Employee Stock Compensation Plans:
On June 18, 2013, Solitario’s shareholders approved the Solitario Resources Corporation Omnibus Stock Incentive Plan or(the “2013 Plan”). Under the terms of the 2013 Plan, as amended, a total of December 31, 2016.

In the future, our5,750,000 shares of Solitario common stock are reserved for awards to directors, officers, employees and directors may receive additional equity based awards pursuant toconsultants.

12. Shareholders’ equity and accumulated other comprehensive income
We adopted ASU 2016-01, “Financial Instruments – Overall (subtopic 825-10) Recognition and Measurement of Financial Assets and Liabilities,” (“ASU 2016-01”). ASU 2016-01 revises the classification and measurement of investment in whichcertain equity investments and the presentation of certain fair value changes for certain financial liabilities measured at fair value. ASU 2016-01 requires the change in fair value of many equity investments to be recognized in net income. Solitario adopted ASU 2016-01 in the first quarter of 2018. Solitario recorded a Changecumulative-effect adjustment for the change in Controlaccounting principle from other comprehensive income in the equity section of the consolidated balance sheet to accumulated deficit of $576,000 related to the adoption of ASU 2016-01.
13. Share Repurchase Program
On October 28, 2015, Solitario’s Board of Directors approved a share repurchase program that authorized Solitario to purchase up to two million shares of its outstanding common stock. During 2019 Solitario’s Board of Directors extended the expiration date of the share repurchase program through December 31, 2020. During the years ended December 31, 2019 and 2018, Solitario purchased 38,400 and 263,100 shares of Solitario common stock, respectively, for an aggregate purchase price of $13,000 and $101,000, respectively. As of December 31, 2019, Solitario has purchased a total of 969,300 shares for an aggregate purchase price of $462,000 under the share repurchase program since its inception.
13. Subsequent events
Solitario has evaluated events subsequent to December 31, 2019 to assess the need for potential recognition or disclosure in this report. Such events were evaluated through the date these financial statements were available to be issued. Based upon this evaluation, it was determined that no subsequent events occurred that require recognition or disclosure in the financial statements.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None
Item 9A. Controls and Procedures
The management of Solitario is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in the CIC) occurs equal to 2.5 times the base salaryRule 13a-15(e) of the Named Executive Officer. In addition any unvested stock options heldExchange Act). During the fiscal period covered by this report, Solitario's management, with the Named Executive Officer will vest upon the Change in Control. The CIC provides an additional gross up for any taxes due as a result of Excise Tax, as defined by Section 4999 of the Code.

Generally, the CIC defines a "Change in Control" as (i) a person acquiring more than 50% of the outstanding stock of the Company, (ii) the shareholders of the Company approving a merger or acquisition whereby more than 50% of the outstanding shares held prior to the vote will be held by a new person or corporation, (iii) the shareholders of the Company approving the sale or disposition of substantially all of the company's assets or (iv) the shareholders of the Company approving a plan of liquidation or dissolution of the Company. During 2015, the Company determined that the Transaction did not constitute a Change in Control as defined in each CIC and did not trigger any compensation due to an officer that is a party to a CIC.

Benefits are payable under each CIC after a Change in Control if the Named Executive Officer terminates his employment for "good reason," or is terminated by the Company, other than for "cause." "Good reason" is generally defined as a reduction in the compensation, level of responsibility or forced relocation, among other things. "Cause" is generally defined in the CIC as the conviction of a felony, gross and willful failure to perform assigned duties, and dishonest conduct that is intentional and materially injurious to the Company.

Tax Implications of Executive Compensation

Under Section 162(m) of the Code, the Company generally receives a tax deduction for compensation on payments which total less than $1,000,000 paid to our Named Executive Officers, unless that compensation is performance based. The total non-performance based compensation for any of our Named Executive Officers did not exceed $1,000,000 during 2016, nor do we anticipate it will exceed $1,000,000 for the foreseeable future.

Stock Ownership Guidelines

Solitario has not established formal stock ownership guidelines for our Named Executive Officers. The Company's Insider Trading Policy prohibits the Named Executive Officers, as well as other insiders, who may have access to material inside information, from purchasing, selling, entering into short sale transactions, engaging in hedging or offsetting transactions regarding Solitario's Common Stock during periods where such persons have access to material inside information.

Compensation Policies with Regard to Risk Management

The Board is responsible for the overall risk management of the Company. Solitario is subject to the inherent risks involved in the exploration and development of mineral properties and shareholders should carefully review Item 1A, “Risk Factors,” in our Annual Report on Form 10-K for the year ended December 31, 2016. However, Solitario does not have any compensation plans or incentives for our Named Executive Officers or any employee for any risk taking activity or risk management activities. Solitario does not engage in activities that have traditional incentives for financial risk taking activities, such as buying or selling derivatives or other similar instruments, other than our limited use of derivatives to reduce our exposure to our holdings of Kinross common stock and the holdings of Vendetta Mining Corp. (“Vendetta”) warrants, which were acquired during 2016.

Roleparticipation of the Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of Solitario’s internal control over financial reporting and the design and operation of Solitario’s disclosure controls and procedures (as defined in Compensation Decisions

TheRule 13a-15(e) of the Exchange Act). This evaluation of the effectiveness of our internal control over financial reporting was based on the framework and criteria established in Internal ControlIntegrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on such evaluations, Solitario’s Chief Executive Officer (“CEO”) annually reviewsand Chief Financial Officer have concluded that, as of December 31, 2019, Solitario’s internal control over financial reporting is effective and that its disclosure controls and procedures are effective to ensure that information required to be disclosed by Solitario in reports that it files or submits under the performance of all other NamedExchange Act is recorded, processed, summarized and reported within the required time periods and are designed to ensure that information required to be disclosed in its reports is accumulated and communicated to Solitario’s management, including the Chief Executive Officers. The performance ofOfficer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. There were no changes in internal control over financial reporting during the CEO is reviewed by the Chairman of the Compensation Committee. The conclusions and recommendations, which include salary, bonus and equity grants, if any, are presented to the Compensation Committee, which has absolute discretion in modifying or applying any of the recommendations for the Named Executive Officers. The Compensation Committee presents its conclusions and recommendations to the Board for their input and review.

Potential Payments upon Termination or Change in Control

As noted under "Compensation Discussion and Analysis" above, the Company entered into certain change in control agreements on March 14, 2007 with the following Named Executive Officers: Christopher E. Herald, James R. Maronick and Walter H. Hunt (as defined above, each such agreement being a “CIC”). The terms of the CICs are more fully described under "Change in Control Agreements"information set forth in the "Compensation Discussion and Analysis" section above. The potential payments to each Named Executive Officer are described below in the event of an assumed change in control as defined in the applicable CIC as of December 31, 2016.

Walter H, Hunt, COO  407,500   —     —     400,000 

(1)Two and one half times base salary as of December 31, 2016. Paid as a lump sum payment.
(2)None of our Named Executive Officers have any outstanding options or equity awards at December 31, 2016. Accordingly, there was no intrinsic value from the acceleration of any unvested options owned by the Named Executive Officer as of December 31, 2016.
(3)The change in control provides for a gross-up for taxes in the event the combined salary and all other compensation, triggered by a change in control, results in Excise Tax, as defined by Section 4999 of the Code. The CIC provide for additional cash compensation to pay the Named Executive Officer for the Excise Tax, which is 20% of all compensation in excess of the base salary amount, when the total payments, including the fair value from acceleration of vesting for unvested options, under the CIC exceed three times base salary. We have estimated that no tax gross up would have been due or payable as of December 31, 2016 because the total compensation, including the fair value from the acceleration of any outstanding unvested options would not exceed three times the base salary.
