Cautionary Note to the Form 10-K (this “Amendment”) amends the Annual Report on Form 10-KU.S. Residents Concerning Disclosure of Mineral Resources

Bunker Hill Mining Corp. (“Bunker Hill,” “we,” “us,” “our” or the “Company”) is a U.S. domestic issuer for U.S. Securities and Exchange Commission (“SEC”) purposes, it is required to report its financial results under U.S. Generally Accepted Accounting Principles (“U.S. GAAP”), and its shares of common stock trade on the year ended June 30, 2029 filed on October 22, 2019Canadian Securities Exchange (the “Form 10-K”“CSE”) and the OTCQB Venture Market. However, certain prior regulatory filings made in Canada contain or incorporate by reference therein certain disclosure that satisfies the additional requirements of Canadian securities laws, which differ from the requirements of United States’ securities laws. Unless otherwise indicated, all resource estimates included in those Canadian filings, and in the documents incorporated by reference therein, had been prepared in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) classification system. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.

Canadian standards, including NI 43-101, may differ from the requirements of subpart 1300 of Regulation S-K (“S-K 1300”). Thus, resource information contained, or incorporated by reference, in the Company’s Canadian filings, and in the documents incorporated by reference therein, may not be comparable to similar information disclosed by companies reporting mineral reserve and mineral resource information under S-K 1300.

The purposeterms “mineral reserve,” “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms as defined in accordance with NI 43-101 and CIM standards. Pursuant to S-K 1300, the SEC now recognizes estimates of this Amendment“measured mineral resources,” “indicated mineral resources” and “inferred mineral resources.” In addition, the SEC has amended its definitions of “proven mineral reserves” and “probably mineral reserves” to be substantially similar to the corresponding standards of the CIM.

Investors are cautioned that while terms are substantially similar to CIM standards, there are differences in the definitions and standards under S-K 1300 and the CIM standards. Accordingly, there is to restate and amend previously issued financial statements. In November 2020, it was determinedno assurance any mineral reserves or mineral resources that the Company may report as “proven reserves,” “probable reserves,” “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources” under NI 43-101 will be the same as the reserve or resource estimates prepared under the standards adopted under S-K 1300.

Investors are also cautioned that while the SEC now recognizes “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources,” investors should not assume that any part or all of mineral deposits in these categories will ever be converted into mineral reserves.

Mineralization described using these terms has underaccrued for invoices issueda great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an “measured mineral resource,” “indicated mineral resource” or “inferred mineral resource” will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures.

ITEM 1. BUSINESS

Our Business

Overview

The Company’s sole focus is the United Statesdevelopment and restart of its 100% owned flagship asset, the Bunker Hill mine (the “Mine”) in Idaho, USA. The Mine remains the largest single producing mine by tonnage in the Silver Valley region of northwest Idaho, producing over 165 million ounces of silver and 5 million tons of base metals between 1885 and 1981. The Bunker Hill Mine is located within Operable Unit 2 of the Bunker Hill Superfund site (EPA National Priorities Listing IDD048340921), where cleanup activities have been completed.

In early 2020, a new management team comprised of former executives from Barrick Gold Corp. assumed leadership of the Company. Since that time, the Company conducted multiple exploration campaigns, published multiple economic studies and Mineral Resource Estimates, and advanced the rehabilitation and development of the Mine. In December 2021, it announced a project finance package with Sprott Private Resource Streaming & Royalty Corp. (“Sprott”), an amended Settlement Agreement with the U.S. Environmental Protection Agency ("EPA"(“the EPA”) for excess water treatment costs relating to years ended June 30, 2018, and 2019 and interest payable on the outstanding EPA balance, which resulted in an understatementpurchase of liabilities for 2018 and 2019, an understatement of opening deficit for 2019 and closing deficit for 2018 and 2019, and an understatement of exploration expenses and net losses for 2018 and 2019.

Current Operations

Overview

The Company was incorporated for the initial purpose of engaging in mineral exploration activities at the Mine. The Company has moved into the development stage concurrent with (i) purchasing the Mine and development activities.  On August 28, 2017,a process plant, (ii) completing successive technical and economic studies, including a Prefeasibility Study, (iii) delineating mineral reserves, and (iv) conducting the Company announced that it signed a definitive agreement (the “Agreement”) for the leaseprogram of activities outlined above.

Lease and option to purchasePurchase of the Bunker Hill Mine (the “Mine”)

The Company purchased the Bunker Hill Mine in Idaho. The “Bunker Hill Lease with OptionJanuary 2022, as described below.

Prior to Purchase” is betweenpurchasing the Mine, the Company andhad entered into a series of agreements with Placer Mining Corporation (“Placer Mining”), the currentprior owner, of the Mine.

On October 2, 2018, the Company announced that it was in default of its Lease with Option to Purchase Agreement with Placer Mining. The default arose as a result of missed lease and operating cost payments, totaling $400,000, which were due at the end of September and on October 1, 2018. As per the Agreement, the Company had 15 days, from the date notice of default was provided (September 28, 2018), to remediate the default by making the outstanding payment. While Management worked with urgency to resolve this matter, Management was ultimately unsuccessful in remedying the default, resulting infor the lease being terminated. On November 13, 2018, the Company announced that it was successful in renewing the lease.

The 24-month lease continues until October 31, 2019. The lease period can be extended by a further 12 months at the Company’s discretion.  Under the revised terms of its agreement, during the term of the lease, the Company must make $60,000 monthly mining lease payments.  A monthly amount of $140,000 is deferred and becomes payable if the Company exercises its purchase option, making the deferred amount payable.  The Company is accruing for these payments and includes them in accounts payable.

The Company has an option to purchase the Bunker Hill Mine assets (“Mine. The first of these agreements was announced on August 28, 2017, with subsequent amendments and/or extensions announced on November 1, 2019, July 7, 2020, and November 20, 2020.

Under termscredited toward the purchase price of the agreement, there is a 3% net smelter return royaltyMine as having been previously paid by the Company) and $2,000,000 in shares of common stock of the Company (“NSR”Common Shares”) on sales during the Lease and a 1.5% NSR on the sales after. The Company agreed to make an advance payment of $2,000,000, credited toward the purchase option is exercised,price of the Mine, which post-acquisition NSR is capped at $60 million.had the effect of decreasing the remaining amount payable to purchase the Mine to an aggregate of $3,400,000 payable in cash and $2,000,000 in Common Shares of the Company.

In addition to the

The Amended Agreement also required payments to Placer Mining, pursuant to an agreement with the United States Environmental Protection Agency (“EPA”)EPA whereby for so long as Bunkerthe Company leases, owns and/or occupies the Bunker Hill Mine, the Company willwould make payments to the EPA on behalf of the current ownerPlacer Mining in satisfaction of the EPA’s claim for historical water treatment cost recovery.  Theserecovery in accordance with the Settlement Agreement reached with the EPA in 2018. Immediately prior to the purchase of the Mine, the Company’s liability to EPA in this regard totaled $11,000,000.

The Company completed the purchase of the Bunker Hill Mine on January 7, 2022. The terms of the purchase price were modified to $5,400,000 in cash, from $3,400,000 of cash and $2,000,000 of Common Shares. Concurrent with the purchase of the Mine, the Company assumed incremental liabilities of $8,000,000 to the EPA, consistent with the terms of the amended Settlement Agreement with the EPA that was executed in December 2021 (see “EPA 2018 Settlement Agreement & 2021 Amended Settlement Agreement” section below).

EPA 2018 Settlement Agreement & 2021 Amended Settlement Agreement

Bunker Hill entered into a Settlement Agreement and Order on Consent with the EPA on May 15, 2018. This agreement limits the Company’s exposure to the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) liability for past environmental damage to the mine site and surrounding area to obligations that include:

In December 2021, in conjunction with its intention to purchase the mine complex, the Company entered into an amended Settlement Agreement (the “Amendment”) between the Company, Idaho Department of Environmental Quality, US Department of Justice and the EPA modifying the payment schedule and payment terms for recovery of historical environmental response costs at Bunker Hill Mine incurred by the EPA. With the purchase of the mine in early 2022, the remaining payments if all are made, willof the EPA cost recovery liability were assumed by the Company, resulting in a total $20 million.of $19,000,000 liability to the Company, an increase of $8,000,000. The agreement calls for payments starting with $1 millionnew payment schedule included a $2,000,000 payment to the EPA within 30 days after a fully ratified agreementof execution of this amendment, which was signed (whichmade.

The remaining $17,000,000 will be paid on the following dates:

On January 25, 2022, the Company announced that it had entered into a non-binding Memorandum of Understanding (“MOU”) with the EPA to amend and defer payments.

The Company also has received invoices from the EPA for water treatment chargesTeck Resources Limited (“Teck”) for the periodspurchase of a comprehensive package of equipment and parts inventory from December 2017 to October 2019. This was for a total of $3,269,388, with $1,209,530 additional accruals required as at June 30, 2019. The Company is having discussions withits Pend Oreille site (the “Process Plant”) in eastern Washington State, approximately 145 miles from the EPA to review and, where appropriate, have the additional water treatment charges amended. The unpaid EPA balance is subject to interest at the rate specified for interest on investments of the EPA Hazardous Substance Superfund.

Management believes this amended lease and option will provide the Company time to complete exploratory drilling, produce a mine plan and raise the money needed to move forward.  Management continues to push forward and advance the time line to realizing shareholder value.

The Bunker Hill Mine wasby road. The package comprises substantially all processing equipment of value located at the largest producing mine in the Coeur d'Alene zinc, leadsite, including complete crushing, grinding and silver mining district in northern Idaho.  Historically, the mine produced over 35M tonnesflotation circuits suitable for a planned ~1,500 ton-per-day operation at Bunker Hill, and total inventory of ore grading on average 8.76% lead, 3.67% zinc,nearly 10,000 components and 155 g/t silver (Bunker Hill Mines Annual Report 1980). 

parts for mill, assay lab, conveyer, field instruments, and electrical spares. The Company believespaid a $500,000 non-refundable deposit in January 2022.

On March 31, 2022, the Company announced that there are numerous targets of opportunity left in the mine from top to bottom, and particularly on a strike to the west where more recent past drilling has resulted in major discoveries such as the Quill body of mineralized material.

Government Regulation and Approval

The current exploration

Exploration and development activities, and any future mining operations, are subject to extensive laws and regulations governing the protection of the environment, waste disposal, worker safety, mine construction, and protection of endangered and protected species. The Company has made, and expects to make in the future, significant expenditures to comply with such laws and regulations. Future changes in applicable laws, regulations and permits or changes in their enforcement or regulatory interpretation could have an adverse impact on the Company’s financial condition or results of operations.

It is anticipated that it may be necessary to obtain the following environmental permits or approved plans prior to commencement of mine operations:

Property Description

The Company’s agreement with Placer Mining Corporation includesCompany has mineral rights to 434approximately 440 patented mining claims covering 5769.467 acres of thoseover 5700 acres. Of these claims, 35 include surface ownership overof approximately 259.1259 acres. The transactionIt also includeshas certain parcels of fee property which includesinclude mineral and surface rights but are not patented mining claims. Mining claims and fee properties are located in Townships 47, 48 North, Range 2 East, Townships 47, 48 North, Range 3 East, Boise Meridian, Shoshone County, Idaho. The agreement specifically excludes the following: the Machine Shop Building and Parcel, including all fixed equipment located inside the building and personal property located upon the parcel; unmilled ore on deck and residual lead/zinc ore mined and broken, but not removed from the Bunker Hill Mine; the historic Caledonia Mine; the Crystal Vug; and the Silver Ridge exploration property.

Surface rights were originally owned by various previous owners of the claims until the acquisition of the properties by Bunker Limited Partners (“BLP”).  BLP sold off surface rights to various parties over the years while maintaining access to conduct mining operations and exploration activities as well as easements to a cross over and access other of its properties containing mineral rights. Said rights were reserved to its assigns and successors in continuous perpetuity. Idaho Law also allows mineral right holders access to mine and explore for minerals on properties to which they hold minerals rights.

Title to all patented mining claims included in the transaction was transferred from Bunker Hill Mining Co. (U.S.) Inc. by Warranty Deed in 1992. The sale of the property was properly approved of by the U.S. Trustee and U.S. Bankruptcy Court.  

Over 90% of surface ownership of patented mining claims not owned by Placer Mining Corp. is owned by different landowners. These include: Stimpson Lumber Co.; Riley Creek Lumber Co.; Powder LLC.; Golf LLC.; C & E Tree Farms; and Northern Lands LLC.

Patented mining claims in the State of Idaho do not require permits for underground mining activities to commence on private lands. Other permits associated with underground mining may be required, such as water discharge and site disturbance permits. The water discharge is being handled by the EPA at the existing water treatment plant.CTP. The Company expects to take on the water treatment responsibility in the future and obtain an appropriate discharge permit.  If

below.

Competition

The Company competes with other mining and exploration companies in connection with the acquisition of mining claims and leases on zinc and other base and precious metals prospects as well as in connection with the recruitment and retention of qualified employees. Many of these companies are much larger than the Company, have greater financial resources and have been in the mining business for much longer than it has. As such, these competitors may be in a better position through size, finances and experience to acquire suitable exploration and development properties. The Company may not be able to compete against these companies in acquiring new properties and/or qualified people to work on its current project, or any other properties that may be acquired in the future.

Given the size of the world market for base precious metals such as silver, lead and zinc, relative to the number of individual producers and consumers, it is believed that no single company has sufficient market influence to significantly affect the price or supply of these metals in the world market.

Employees

Employees

The Company has ten employees. The balance of the Company’s operations is currently managed by John Ryan, President and CEO and Wayne Parsons, Chief Financial Officer.contracted for as consultants.

Reports to Security Holders

The Company files reports with the SEC under section 15d of the Securities Exchange Act of 1934.1934 (the “Exchange Act”). The reports will be filed electronically. All copies of any materials filed with the SEC may be read at the SEC'sSEC’s Public Reference Room at 100 F Street, NE, Room 1580, Washington, D.C. 20549. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 1-800-SEC-0330. The SEC also maintains an Internet site that will contain copies of the reports that are filed electronically. The address for the SEC Internet site is http://www.sec.gov.www.sec.gov.

ITEM 1A. RISK FACTORS

Not Applicable.

As a Smaller Reporting Company, this item is not required under SEC rules. However, the Company believes that it is important to have an understanding of the risks associated with an investment in the Company. In addition, these risk factors are incorporated by reference in press releases and other Company publications for purposes of the Private Securities Reform Act of 1995.

General Risk Factors

The Company’s ability to operate as a going concern is in doubt.

The audit opinion and notes that accompany the Company’s Financial Statements disclose a going concern qualification to its ability to continue in business. The accompanying Financial Statements have been prepared under the assumption that the Company will continue as a going concern. The Company is an exploration and development stage company and has incurred losses since its inception. The Company has incurred losses resulting in an accumulated deficit of $71,592,559 as of December 31, 2022 and further losses are anticipated in the development of its business.

The Company currently has no historical recurring source of revenue and its ability to continue as a going concern is dependent on its ability to raise capital to fund its future exploration and working capital requirements or its ability to profitably execute its business plan. The Company’s plans for the long-term return to and continuation as a going concern include financing its future operations through sales of its Common Shares and/or debt and the eventual profitable exploitation of the Mine. Additionally, the volatility in capital markets and general economic conditions in the U.S. and elsewhere can pose significant challenges to raising the required funds. These factors raise substantial doubt about the Company’s ability to continue as a going concern.

The Company’s consolidated financial statements do not give effect to any adjustments required to realize its assets and discharge its liabilities in other than the normal course of business and at amounts different from those reflected in the accompanying Financial Statements.

The Company will require significant additional capital to fund its short-term obligations, continue its operations and remain in compliance with its debt agreements.

Neither the Company nor any of the directors of the Company nor any other party can provide any guarantee or assurance that the Company will be able to raise sufficient capital to satisfy the Company’s short-term obligations. The Company does not have sufficient funds to satisfy its short-term financial obligations, even after consideration of its recently completed equity financing. As at December 31, 2022, the Company had $708,105 in cash and total current liabilities of $10,155,582 and total liabilities of $59,106,835. The Company will likely require additional capital by the end of the second quarter of 2023 in order to continue its operations. Further, if the Company does not raise sufficient additional capital, the Company will be in breach of its debt agreements, including under the RCD, CD1, CD2 and Bridge Loan.

The Company may not be able to secure the Stream or alternative funding from Sprott or another capital provider.

Neither the Company nor any of the directors of the Company nor any other party can provide any guarantee or assurance that the Stream, the final contemplated tranche of the full $66,000,000 project financing package, will be finalized or close, or any other funding from Sprott. The Stream remains subject to Sprott internal approvals, full project funding, further technical and other due diligence and satisfactory documentation. If the Stream, or a portion thereof, does not close there is no guarantee that alternative capital can be raised on terms favorable to the Company, or at all.

Any additional equity funding, for which there can be no guarantee or assurance with regard to any amount or terms thereof, will dilute existing shareholders.

A concentrate offtake agreement with Teck Resources may not be reached, which could result in less favorable commercial terms for the sale of concentrates envisaged to be produced by the Bunker Hill Mine and could also impact the Company’s ability to secure offtake financing. Regardless of actions taken by Teck, there can be no assurance that the Company will be able to secure or close offtake financing, which could have an adverse effect on the Company’s financial position and negative impact the Company’s ability to secure additional funding from Sprott or an alternative capital provider.

The Company may not be able to execute a concentrate offtake agreement for the sale of concentrates to Teck Resources at its Trail smelter, as contemplated with Teck’s option to acquire 100% of zinc and lead concentrate produced in the first five years at the Bunker Hill Mine. If such an agreement cannot be reached, the Company may not be able to sell its zinc and lead concentrate to Teck, which could result in difficulties securing alternative commercial arrangements for the sale of concentrate, less favorable commercial terms in the event that alternative commercial arrangements can be secured, and/or higher transportation and other costs. In addition, the Company may not be able to secure or close offtake financing, regardless of whether an agreement is reached with Teck; the terms of any offtake financing might not be favorable to the Company; and/or the Company may incur substantial fees and costs related to such financing. The Company’s inability to secure or close offtake financing, or arrange a suitable alternative, may have an adverse effect on the Company’s operations and financial position, including its ability to secure the Stream from Sprott.

The Bunker Hill Mine restart is now expected to take place in 2024, with first concentrate production targeted for mid-2024. Changes to this timeline, or other factors impacting the restart project budget, could increase the Company’s required capital needs through the completion of the project, which would adversely affect the Company’s ability to secure additional funding, thereby adversely affecting its financial condition.

On February 28, 2023, the Company announced that primarily due to the inability to procure certain long-lead items that were planned to be ordered by February 2023, and longer estimated delivery times thereof, the Company now expects the Bunker Hill Mine restart to be achieved in 2024. On March 10, 2023, the Company announced that it has maintained the integrity of its total pre-production budget, under the assumption of first concentrate production in the second quarter of 2024.

In the event that the Company is unable to secure sufficient funding to materially advance the restart of the Mine in the second quarter of 2023, from Sprott or an alternative capital provider, it is likely that the restart timeline will be further delayed with a potentially materially adverse effect on the pre-production budget.

Notwithstanding financing-related risks, the Company’s pre-production budget estimates are subject to change based on factors beyond its control, including but not limited to cost inflation and supply chain dynamics. An increase in the Company’s pre-production budget estimates could have a materially adverse impact on its ability to secure project financing. This could have a material adverse effect on its financial condition, results of operations, or prospects. Sales of substantial amounts of securities may have a highly dilutive effect on the Company’s ownership or share structure. Sales of a large number of shares of the Company’s Common Shares in the public markets, or the potential for such sales, could decrease the trading price of the Common Shares and could impair the Company’s ability to raise capital through future sales of Common Shares. The Company has not yet commenced commercial production at any of its properties and, therefore, has not generated positive cash flows to date and has no reasonable prospects of doing so unless successful commercial production can be achieved at the Mine. The Company expects to continue to incur negative investing and operating cash flows until such time as it enters into successful commercial production. This will require the Company to deploy its working capital to fund such negative cash flow and to seek additional sources of financing. There is no assurance that any such financing sources will be available or sufficient to meet the Company’s requirements, or if available, available upon terms acceptable to the Company. There is no assurance that the Company will be able to continue to raise equity capital or to secure additional debt financing, or that the Company will not continue to incur losses.

Payment bonds securing $17,000,000 due by the Company to the EPA for cost recovery may not be renewable or may only be renewable on terms that are unfavorable to the Company, which would adversely affect its financial condition or cause a default under the revised settlement agreement with the EPA and Sprott.

In 2022, the Company secured financial assurance in the form of payment bonds in accordance with the revised settlement agreement with the EPA, in relation to $17,000,000 of payments due to the EPA for cost recovery between 2024-2029. These bonds are renewed annually, and currently require $6,476,000 of collateral in the form of letters of credit. To the extent that the parties providing the payment bonds demand additional collateral beyond the current requirements, or other unfavorable terms or conditions, the Company may not be able to renew the payment bonds on favorable conditions, or at all. This could have a materially adverse impact on the Company, including a potential default under the revised settlement agreement with the EPA.

The Company has a limited operating history on which to base an evaluation of its business and prospects.

Since its inception, the Company has had no revenue from operations. The Company has no history of producing products from the Bunker Hill property. The Mine is a historic, past producing mine with very little recent exploration work. Advancing the Mine through the development stage will require significant capital and time, and successful commercial production from the Mine will be subject to completing the requisite studies, permitting and re-commissioning of the Mine, constructing a processing plant, and other related works and infrastructure. As a result, the Company is subject to all of the risks associated with developing and establishing new mining operations and business enterprises, including:

The costs, timing, and complexities of exploration, development, and construction activities may be increased by the location of its properties and demand by other mineral exploration and mining companies. It is common in exploration programs to experience unexpected problems and delays during drill programs and, if commenced, development, construction, and mine start-up. In addition, the Company’s management and workforce will need to be expanded, and sufficient housing and other support systems for its workforce will have to be established. This could result in delays in the commencement of mineral production and increased costs of production. Accordingly, the Company’s activities may not result in profitable mining operations, and it may not succeed in establishing mining operations or profitably producing metals at any of its current or future properties, including the Mine.

The Company has a history of losses and expects to continue to incur losses in the future.

The Company has incurred losses since inception, has had negative cash flow from operating activities, and expects to continue to incur losses in the future. The Company has incurred the following losses from operations during each of the following periods:

The Company expects to continue to incur losses unless and until such time as the Mine enters into commercial production and generates sufficient revenues to fund continuing operations. The Company recognizes that if it is unable to generate significant revenues from mining operations and dispositions of its properties, the Company will not be able to earn profits or continue operations. At this early stage of its operation, the Company also expects to face the risks, uncertainties, expenses, and difficulties frequently encountered by smaller reporting companies. The Company cannot be sure that it will be successful in addressing these risks and uncertainties and its failure to do so could have a materially adverse effect on its financial condition.

Epidemics, pandemics or other public health crises, including COVID-19, could adversely affect the Company’s business.

The Company’s operations could be significantly adversely affected by the effects of a widespread outbreak of epidemics, pandemics or other health crises, including the recent outbreak of respiratory illness caused by the novel coronavirus (“COVID-19”), which was declared a pandemic by the World Health Organization on March 12, 2020. The Company cannot accurately predict the impact COVID-19 or some future variant would have on its operations and the ability of others to meet their obligations with the Company, including uncertainties relating to the ultimate geographic spread of the virus, the severity of the disease, the duration of the outbreak, and the length of travel and quarantine restrictions imposed by governments of affected countries. In addition, a significant outbreak of contagious diseases in the human population could result in a widespread health crisis that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn that could further affect the Company’s operations and ability to finance its operations.

The Russia/Ukraine crisis, including the impact of sanctions or retributions thereto, could adversely affect the Company’s business.

The Company’s operations could be adversely affected by the effects of the escalating Russia/Ukraine crisis and the effects of sanctions imposed against Russia or that country’s retributions against those sanctions, embargos or further-reaching impacts upon energy prices, food prices and market disruptions. The Company cannot accurately predict the impact the crisis will have on its operations and the ability of contractors to meet their obligations with the Company, including uncertainties relating the severity of its effects, the duration of the conflict, and the length and magnitude of energy bans, embargos and restrictions imposed by governments. In addition, the crisis could adversely affect the economies and financial markets of the United States in general, resulting in an economic downturn that could further affect the Company’s operations and ability to finance its operations. Additionally, the Company cannot predict changes in precious metals pricing or changes in commodities pricing which may alternately affect the Company either positively or negatively.

Risks Related to Mining and Exploration

The Company is in the development stage.

The nature of mineral exploration and production activities involves a high degree of risk and the possibility of uninsured losses.

Exploration for and the production of minerals is highly speculative and involves much greater risk than many other businesses. Most exploration programs do not result in the discovery of mineralization, and any mineralization discovered may not be of sufficient quantity or quality to be profitably mined. The Company’s operations are, and any future development or mining operations the Company may conduct will be, subject to all of the operating hazards and risks normally incidental to exploring for and development of mineral properties, including, but not limited to:

Any of these risks can materially and adversely affect, among other things, the development of properties, production quantities and rates, costs and expenditures, potential revenues, and production dates. If the Company determines that capitalized costs associated with any of its mineral interests are not likely to be recovered, the Company would incur a write-down of its investment in these interests. All these factors may result in losses in relation to amounts spent that are not recoverable, or that result in additional expenses.

Commodity price volatility could have dramatic effects on the results of operations and the Company’s ability to execute its business plan.

The price of commodities varies on a daily basis. The Company’s future revenues, if any, will likely be derived from the extraction and sale of base and precious metals. The price of those commodities has fluctuated widely, particularly in recent years, and is affected by numerous factors beyond its control including economic and political trends, expectations of inflation, currency exchange fluctuations, interest rates, global and regional consumptive patterns, speculative activities and increased production due to new extraction developments and improved extraction and production methods. The effect of these factors on the price of base and precious metals, and therefore the economic viability of the Company’s business, could negatively affect its ability to secure financing or its results of operations.

The Company’s development and production plans, and cost estimates, in the Technical Report Summary may vary and/or not be achieved.

There is no certainty that the Technical Report Summary will be realized. The decision to implement the Mine restart scenario to be included in the Technical Report Summary will not be based on a feasibility study of mineral reserves demonstrating economic and technical viability, and therefore there is increased risk that the Technical Report Summary results will not be realized. If the Company is unable to achieve the results in the Technical Report Summary, it may have a material negative impact on the Company and its capital investment to implement the restart scenario may be lost.

Costs charged to the Company by the Idaho Department of Environmental Quality (“IDEQ”) for treatment of wastewater fluctuate a great deal and are not within the Company’s control.

The Company is billed annually for water treatment activities performed by the IDEQ for the EPA. The water treatment costs that Bunker Hill is billed for are partially related to the EPA’s direct cost of treating the water emanating from the Bunker Hill Mine, which are comprised of lime and flocculant usage, electricity consumption, maintenance and repair, labor and some overhead. Rate of discharge of effluent from the Bunker Hill Mine is largely dependent on the level of precipitation within a given year and how close in the calendar year the Company is to the spring run-off. Increases in water infiltrations and gravity flows within the mine generally increase after winter and result in a peak discharge rate in May. Increases in gravity flow and consequently the rate of water discharged by the mine have a highly robust correlation with metal concentrations and consequently metals loads of effluent.

Hydraulic loads (quantities of water per unit of time) and metal loads (quantities of metals per unit of volume of effluent per unit of time) are the two main determinants of cost of water treatment by the EPA in the relationship with the Bunker Hill Mine because greater metal loads consume more lime and more flocculent and more electricity to remove the increased levels of metals and make the water clean. The scale of the treatment plant is determined by how much total water can be processed (hydraulic load) at any one point in time. This determines how much labor is required to operate the plant and generally determines the amount of overhead required to run the EPA business.

The EPA has completed significant upgrades to the water treatment capabilities of the CTP and is now capable of producing treated water than can meet a much higher discharge standard (which Bunker Hill will be forced to meet beyond May 2023). While it was understood that improved performance capability would increase the cost of operating the plant, it was unclear to EPA, and consequently to Bunker Hill, how much the costs would increase by.

These elements described above, and others, impact the direct costs of water treatment. A significant portion of the total amount invoiced by EPA each year is indirect cost that is determined as a percentage of the direct cost. Each year the indirect costs percentage changes within each region of the EPA. Bunker Hill has no ability to impact the percentage of indirect cost that is set by the EPA regional office. Bunker Hill also has no advanced notice of what the percentage of indirect cost will be until it receives its invoice in June of the year following the billing period. The Company remains unable to estimate EPA billings to a high degree of accuracy.

Estimates of mineral reserves and resources are subject to evaluation uncertainties that could result in project failure.

Its exploration and future mining operations, if any, are and would be faced with risks associated with being able to accurately predict the quantity and quality of mineral resources/reserves within the earth using statistical sampling techniques. Estimates of any mineral resource/reserve on the Mine would be made using samples obtained from appropriately placed trenches, test pits, underground workings, and intelligently designed drilling. There is an inherent variability of assays between check and duplicate samples taken adjacent to each other and between sampling points that cannot be reasonably eliminated. Additionally, there also may be unknown geologic details that have not been identified or correctly appreciated at the current level of accumulated knowledge about the Mine. This could result in uncertainties that cannot be reasonably eliminated from the process of estimating mineral resources/reserves. If these estimates were to prove to be unreliable, the Company could implement an exploitation plan that may not lead to commercially viable operations in the future.

Any material changes in mineral resource/reserve estimates and grades of mineralization will affect the economic viability of placing a property into production and a property’s return on capital.

As the Company has not commenced actual production, mineral resource estimates may require adjustments or downward revisions. In addition, the grade of ore ultimately mined, if any, may differ from that indicated by future feasibility studies and drill results. Minerals recovered in small scale tests may not be duplicated in large scale tests under on-site conditions or in production scale.

The Company’s exploration activities may not be commercially successful, which could lead the Company to abandon its plans to develop the Mine and its investments in exploration.

The Company’s long-term success depends on its ability to identify mineral deposits on the Mine and other properties the Company may acquire, if any, that the Company can then develop into commercially viable mining operations. Mineral exploration is highly speculative in nature, involves many risks, and is frequently non-productive. These risks include unusual or unexpected geologic formations, and the inability to obtain suitable or adequate machinery, equipment, or labor. The success of commodity exploration is determined in part by the following factors:

Substantial expenditures are required to establish proven and probable reserves through drilling and analysis, to develop metallurgical processes to extract metal, and to develop the mining and processing facilities and infrastructure at any site chosen for mining. Whether a mineral deposit will be commercially viable depends on a number of factors that include, without limitation, the particular attributes of the deposit, such as size, grade, and proximity to infrastructure; commodity prices, which can fluctuate widely; and government regulations, including, without limitation, regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals, and environmental protection. The Company may invest significant capital and resources in exploration activities and may abandon such investments if the Company is unable to identify commercially exploitable mineral reserves. The decision to abandon a project may have an adverse effect on the market value of the Company’s securities and the ability to raise future financing.

The Company is subject to significant governmental regulations that affect its operations and costs of conducting its business and may not be able to obtain all required permits and licenses to place its properties into production.

The Company’s current and future operations, including exploration and, development of the Mine, do and will require permits from governmental authorities and will be governed by laws and regulations, including:

Specifically, it may be necessary to obtain the following environmental permits or approved plans prior to commencement of mine operations:

If these permits are required, there can be no assurance that the Company will be able to obtain them in a timely manner or at all.

Companies engaged in exploration activities often experience increased costs and delays in production and other schedules as a result of the need to comply with applicable laws, regulations, and permits. Failure to comply with applicable laws, regulations, and permits may result in enforcement actions, including the forfeiture of mineral claims or other mineral tenures, orders issued by regulatory or judicial authorities requiring operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment, or costly remedial actions. The Company cannot predict if all permits that it may require for continued exploration, development, or construction of mining facilities and conduct of mining operations will be obtainable on reasonable terms, if at all. Costs related to applying for and obtaining permits and licenses may be prohibitive and could delay its planned exploration and development activities. The Company may be required to compensate those suffering loss or damage by reason of the mineral exploration or its mining activities, if any, and may have civil or criminal fines or penalties imposed for violations of, or its failure to comply with, such laws, regulations, and permits.

Existing and possible future laws, regulations, and permits governing operations and activities of exploration companies, or more stringent implementation of such laws, regulations and permits, could have a material adverse impact on the Company’s business and cause increases in capital expenditures or require abandonment or delays in exploration. The Mine is located in Northern Idaho and has numerous clearly defined regulations with respect to permitting mines, which could potentially impact the total time to market for the project.

The Company’s activities are subject to environmental laws and regulations that may increase its costs of doing business and restrict its operations.

Both mineral exploration and extraction require permits from various federal, state, and local governmental authorities and are governed by laws and regulations, including those with respect to prospecting, mine development, mineral production, transport, export, taxation, labor standards, occupational health, waste disposal, toxic substances, land use, environmental protection, mine safety and other matters. There can be no assurance that the Company will be able to obtain or maintain any of the permits required for the exploration of the mineral properties or for the construction and operation of the Mine at economically viable costs. If the Company cannot accomplish these objectives, its business could fail. The Company believes that it is in compliance with all material laws and regulations that currently apply to its activities but there can be no assurance that the Company can continue to remain in compliance. Current laws and regulations could be amended, and the Company might not be able to comply with them, as amended. Further, there can be no assurance that the Company will be able to obtain or maintain all permits necessary for its future operations, or that it will be able to obtain them on reasonable terms. To the extent such approvals are required and are not obtained, the Company may be delayed or prohibited from proceeding with planned exploration or development of the mineral properties.

The Company’s activities are subject to extensive laws and regulations governing environmental protection. The Company is also subject to various reclamation-related conditions. Although the Company closely follows and believes it is operating in compliance with all applicable environmental regulations, there can be no assurance that all future requirements will be obtainable on reasonable terms. Failure to comply may result in enforcement actions causing operations to cease or be curtailed and may include corrective measures requiring capital expenditures. Intense lobbying over environmental concerns by non-governmental organizations has caused some governments to cancel or restrict development of mining projects. Current publicized concern over climate change may lead to carbon taxes, requirements for carbon offset purchases or new regulation. The costs or likelihood of such potential issues to the Company cannot be estimated at this time.

The legal framework governing this area is constantly developing, therefore the Company is unable to fully ascertain any future liability that may arise from the implementation of any new laws or regulations, although such laws and regulations are typically strict and may impose severe penalties (financial or otherwise). The proposed activities of the Company, as with any exploration company, may have an environmental impact which may result in unbudgeted delays, damage, loss and other costs and obligations including, without limitation, rehabilitation and/or compensation. There is also a risk that the Company’s operations and financial position may be adversely affected by the actions of environmental groups or any other group or person opposed in general to the Company’s activities and, in particular, the proposed exploration and mining by the Company within the state of Idaho and the United States.

Environmental hazards unknown to the Company, which have been caused by previous or existing owners or operators of the Mine, may exist on the properties in which the Company holds an interest. Many of the properties in which the Company has ownership rights are located within the Coeur d’Alene Mining District, which is currently the site of a Federal Superfund cleanup project. It is possible that environmental cleanup or other environmental restoration procedures could remain to be completed or mandated by law, causing unpredictable and unexpected liabilities to arise.

Regulations and pending legislation governing issues involving climate change could result in increased operating costs, which could have a material adverse effect on the Company’s business.

A number of governments or governmental bodies have introduced or are contemplating legislative and/or regulatory changes in response to concerns about the potential impact of climate change. Legislation and increased regulation regarding climate change could impose significant costs on the Company, on its future venture partners, if any, and on its suppliers, including costs related to increased energy requirements, capital equipment, environmental monitoring and reporting, and other costs necessary to comply with such regulations. Any adopted future climate change regulations could also negatively impact the Company’s ability to compete with companies situated in areas not subject to such limitations. Given the emotional and political significance and uncertainty surrounding the impact of climate change and how it should be dealt with, the Company cannot predict how legislation and regulation will ultimately affect its financial condition, operating performance, and ability to compete. Furthermore, even without such regulation, increased awareness and any adverse publicity in the global marketplace about potential impacts on climate change by the Company or other companies in its industry could harm the Company’s reputation. The potential physical impacts of climate change on its operations are highly uncertain, could be particular to the geographic circumstances in areas in which the Company operates and may include changes in rainfall and storm patterns and intensities, water shortages, changing sea levels, and changing temperatures. These impacts may adversely impact the cost, production, and financial performance of the Company’s operations.

There are several governmental regulations that materially restrict mineral exploration. The Company will be subject to the federal regulations (environmental) and the laws of the State of Idaho as the Company carries out its exploration program. The Company may be required to obtain additional work permits, post bonds and perform remediation work for any physical disturbance to the land in order to comply with these laws. While the Company’s planned exploration program budgets for regulatory compliance, there is a risk that new regulations could increase its costs of doing business and prevent it from carrying out its exploration program.

Land reclamation requirements for the Company’s properties may be burdensome and expensive.

Although variable depending on location and the governing authority, land reclamation requirements are generally imposed on mineral exploration companies (as well as companies with mining operations) in order to minimize long-term effects of land disturbance.

Reclamation may include requirements to:

To date, the Company has not been subject to reclamation or bonding obligations in connection with its past or potential future development activities. If these obligations were to occur in the future, or if the Company is required to carry out reclamation work, the Company must allocate financial resources that might otherwise be spent on further exploration and development programs.

Social and environmental activism may have an adverse effect on the reputation and financial condition of the Company or its relationship with the communities in which it operates.

There is an increasing level of public concern relating to the effects of mining on the nature landscape, in communities and on the environment. Certain non-governmental organizations, public interest groups and reporting organizations (“NGOs”) who oppose resource development can be vocal critics of the mining industry. In addition, there have been many instances in which local community groups have opposed resource extraction activities, which have resulted in disruption and delays to the relevant operation. While the Company seeks to operate in a socially responsible manner and believes it has good relationships with local communities in the regions in which it operates, NGOs or local community organizations could direct adverse publicity against and/or disrupt the operations of the Company in respect to one or more of its properties, regardless of its successful compliance with social and environmental best practices, due to political factors, activities of unrelated third parties on lands in which the Company has an interest or the Company’s operations specifically. Any such actions and the resulting media coverage could have an adverse effect on the reputation and financial condition of the Company or its relationships with the communities in which it operates, which could have a material adverse effect on the Company’s business, financial condition, results of operations, cash flows or prospects.

The mineral exploration and mining industry is highly competitive.

The mining industry is intensely competitive in all of its phases. As a result of this competition, some of which is with large established mining companies with substantial capabilities and with greater financial and technical resources than the Company’s, the Company may be unable to acquire additional properties, if any, or financing on terms it considers acceptable. The Company also competes with other mining companies in the recruitment and retention of qualified managerial and technical employees. If the Company is unable to successfully compete for qualified employees, its exploration and development programs may be slowed down or suspended. The Company competes with other companies that produce its planned commercial products for capital. If the Company is unable to raise sufficient capital, its exploration and development programs may be jeopardized or it may not be able to acquire, develop, or operate additional mining projects.

The silver industry is highly competitive, and the Company is required to compete with other corporations and business entities, many of which have greater resources than it does. Such corporations and other business entities could outbid the Company for potential projects or produce minerals at lower costs, which would have a negative effect on the Company’s operations.

Metal prices are highly volatile. If a profitable market for its metals does not exist, the Company may have to cease operations.

Mineral prices have been highly volatile and are affected by numerous international economic and political factors over which the Company has no control. The Company’s long-term success is highly dependent upon the price of silver, as the economic feasibility of any ore body discovered on its current property, or on other properties the Company may acquire in the future, would, in large part, be determined by the prevailing market price of the minerals. If a profitable market does not exist, the Company may have to cease operations.

A shortage of equipment and supplies could adversely affect the Company’s ability to operate its business.

The Company is dependent on various supplies and equipment to carry out its mining exploration and, if warranted, development operations. Any shortage of such supplies, equipment, and parts could have a material adverse effect on the Company’s ability to carry out its operations and could therefore limit, or increase the cost of, production.

Joint ventures and other partnerships, including offtake arrangements, may expose the Company to risks.

The Company may enter into joint ventures, partnership arrangements, or offtake agreements, with other parties in relation to the exploration, development, and production of the properties in which the Company has an interest. Any failure of such other companies to meet their obligations to the Company or to third parties, or any disputes with respect to the parties’ respective rights and obligations, could have a material adverse effect on the Company, the development and production at its properties, including the Mine, and on future joint ventures, if any, or their properties, and therefore could have a material adverse effect on its results of operations, financial performance, cash flows and the price of its Common Shares.

The Company may experience difficulty attracting and retaining qualified management to meet the needs of its anticipated growth, and the failure to manage its growth effectively could have a material adverse effect on its business and financial condition.

The success of the Company is currently largely dependent on the performance of its directors and officers. The loss of the services of any of these people could have a materially adverse effect on the Company’s business and prospects. There is no assurance the Company can maintain the services of its directors, officers or other qualified personnel required to operate its business. As the Company’s business activity grows, the Company will require additional key financial, administrative and mining personnel as well as additional operations staff. There can be no assurance that these efforts will be successful in attracting, training and retaining qualified personnel as competition for people with these skill sets increase. If the Company is not successful in attracting, training and retaining qualified personnel, the efficiency of its operations could be impaired, which could have an adverse impact on the Company’s operations and financial condition. In addition, the COVID-19 pandemic may cause the Company to have inadequate access to an available skilled workforce and qualified personnel, which could have an adverse impact on the Company’s financial performance and financial condition.

The Company is dependent on a relatively small number of key employees, including its Chief Executive Officer (the “CEO”) and Chief Financial Officer (the “CFO”). The loss of any officer could have an adverse effect on the Company. The Company has no life insurance on any individual, and the Company may be unable to hire a suitable replacement for them on favorable terms, should that become necessary.

The Company may be subject to potential conflicts of interest with its directors and/or officers.

Certain directors and officers of the Company are or may become associated with other mining and/or mineral exploration and development companies which may give rise to conflicts of interest. Directors who have a material interest in any person who is a party to a material contract or a proposed material contract with the Company are required, subject to certain exceptions, to disclose that interest and generally abstain from voting on any resolution to approve such a contract. In addition, directors and officers are required to act honestly and in good faith with a view to the best interests of the Company. Some of the directors and officers of the Company have either other full-time employment or other business or time restrictions placed on them and accordingly, the Company will not be the only business enterprise of these directors and officers. Further, any failure of the directors or officers of the Company to address these conflicts in an appropriate manner or to allocate opportunities that they become aware of to the Company could have a material adverse effect on the Company’s business, financial condition, results of operations, cash flows or prospects.

The Company’s results of operations could be affected by currency fluctuations.

The Company’s properties are currently all located in the U.S. and while most costs associated with these properties are paid in U.S. dollars, a significant amount of its administrative expenses are payable in Canadian dollars. There can be significant swings in the exchange rate between the U.S. dollar and the Canadian dollar. There are no plans at this time to hedge against any exchange rate fluctuations in currencies.

Title to the Company’s properties may be subject to other claims that could affect its property rights and claims.

There are risks that title to the Company’s properties may be challenged or impugned. The Mine is located in Northern Idaho and may be subject to prior unrecorded agreements or transfers and title may be affected by undetected defects.

The Company may be unable to secure surface access or purchase required surface rights.

Although the Company obtains the rights to some or all of the minerals in the ground subject to the mineral tenures that the Company acquires, or has the right to acquire, in some cases the Company may not acquire any rights to, or ownership of, the surface to the areas covered by such mineral tenures. In such cases, applicable mining laws usually provide for rights of access to the surface for the purpose of carrying on mining activities; however, the enforcement of such rights through the courts can be costly and time consuming. It is necessary to negotiate surface access or to purchase the surface rights if long-term access is required. There can be no guarantee that, despite having the right at law to access the surface and carry on mining activities, the Company will be able to negotiate satisfactory agreements with any such existing landowners/occupiers for such access or purchase of such surface rights, and therefore the Company may be unable to carry out planned mining activities. In addition, in circumstances where such access is denied, or no agreement can be reached, the Company may need to rely on the assistance of local officials or the courts in such jurisdiction, the outcomes of which cannot be predicted with any certainty. The Company’s inability to secure surface access or purchase required surface rights could materially and adversely affect its timing, cost, or overall ability to develop any mineral deposits the Company may locate.

The Company’s properties and operations may be subject to litigation or other claims.

From time to time the Company’s properties or operations may be subject to disputes that may result in litigation or other legal claims. The Company may be required to take countermeasures or defend against these claims, which will divert resources and management time from operations. The costs of these claims or adverse filings may have a material effect on its business and results of operations.

Mineral exploration and development is subject to extraordinary operating risks. The Company currently insures against these risks on a limited basis. In the event of a cave-in or similar occurrence, the Company’s liability may exceed its resources and insurance coverage, which would have an adverse impact on the Company.

Mineral exploration, development and production involve many risks. The Company’s operations will be subject to all the hazards and risks inherent in the exploration for mineral resources and, if the Company discovers a mineral resource in commercially exploitable quantity, its operations could be subject to all of the hazards and risks inherent in the development and production of resources, including liability for pollution, cave-ins or similar hazards against which the Company cannot insure or against which the Company may elect not to insure. Any such event could result in work stoppages and damage to property, including damage to the environment. As of the date hereof, the Company currently maintains commercial general liability insurance and umbrella liability insurance against these operating hazards, in connection with its exploration program. The payment of any liabilities that arise from any such occurrence that would not otherwise be covered under the current insurance policies would have a material adverse impact on the Company.

Mineral exploration and development are dependent on adequate infrastructure.

Exploration, development and processing activities depend, to one degree or another, on adequate infrastructure. Reliable roads, bridges, power sources and water supply are important elements of infrastructure, which affect access, capital and operating costs. The lack of availability of acceptable terms or the delay in the availability of any one or more of these items could prevent or delay exploration or development of the Company’s mineral properties. If adequate infrastructure is not available in a timely manner, there can be no assurance that the exploration or development of the Company’s mineral properties will be commenced or completed on a timely basis, if at all. Furthermore, unusual or infrequent weather phenomena, sabotage, government or other interference in the maintenance or provision of necessary infrastructure could adversely affect its operations.

Exploration operations depend on adequate infrastructure. In particular, reliable power sources, water supply, transportation and surface facilities are necessary to explore and develop mineral projects. Failure to adequately meet these infrastructure requirements or changes in the cost of such requirements could affect the Company’s ability to carry out exploration and future development operations and could have a material adverse effect on the Company’s business, financial condition, results of operations, cash flows or prospects.

The Company may purchase additional mining properties.

If the Company loses or abandons its interests in its mineral properties, there is no assurance that it will be able to acquire another mineral property of merit or that such an acquisition would be approved by the CSE, OTCQB or any other applicable security exchanges. There is also no guarantee that the CSE, OTCQB or any other applicable security exchanges, will approve the acquisition of any additional properties by the Company, whether by way of an option or otherwise, should the Company wish to acquire any additional properties.

The Company’s operations are dependent on information technology systems that may be subject to network disruptions

The Company’s operations depend on information technology (“IT”) systems. These IT systems could be subject to network disruptions caused by a variety of sources, including computer viruses, security breaches and cyber-attacks, as well as disruptions resulting from incidents such as cable cuts, damage to physical plants, natural disasters, terrorism, fire, power loss, vandalism and theft. The Company’s operations also depend on the timely maintenance, upgrade and replacement of networks, equipment, IT systems and software, as well as pre-emptive expenses to mitigate the risks of failures. Any of these and other events could result in information system failures, delays and/or increase in capital expenses. The failure of information systems or a component of information systems could, depending on the nature of any such failure, adversely impact the Company’s reputation and results of operations.

Although to date the Company has not experienced any material losses relating to cyber-attacks or other information security breaches, there can be no assurance that the Company will not incur such losses in the future. The Company’s risk and exposure to these matters cannot be fully mitigated because of, among other things, the evolving nature of these threats. As a result, cyber security and the continued development and enhancement of controls, processes and practices designed to protect systems, computers, software, data and networks from attack, damage or unauthorized access remain a priority. As cyber threats continue to evolve, the Company may be required to expend additional resources to continue to modify or enhance protective measures or to investigate and remediate any security vulnerabilities.

The Company is a reporting issuer and reporting requirements under applicable securities laws may increase legal and financial compliance costs

The Company is subject to reporting requirements under applicable securities law, the listing requirements of the CSE, the OTCQB, the SEC and other applicable securities rules and regulations. Compliance with these requirements can increase legal and financial compliance costs, make some activities more difficult, time-consuming or costly, and increase demand on existing systems and resources. Among other things, the Company is required to file annual, quarterly and current reports with respect to its business and results of operations and maintain effective disclosure controls and procedures and internal controls over financial reporting. In order to maintain and, if required, improve disclosure controls and procedures and internal controls over financial reporting to meet this standard, significant resources and management oversight is required. As a result, management’s attention may be diverted from other business concerns, which could harm the Company’s business and results of operations. The Company may need to hire additional employees to comply with these requirements in the future, which would increase its costs and expenses.

Risks Related to the Common Shares

The Company’s Common Share price may be volatile and as a result, investors could lose all or part of their investment.

In addition to volatility associated with equity securities in general, the value of an investor’s investment could decline due to the impact of any of the following factors upon the market price of the Common Shares:

The Company’s Common Share price on the CSE has experienced significant price and volume fluctuations. Stock markets in general have experienced extreme price and volume fluctuations, and the market prices of securities have been highly volatile. These fluctuations are often unrelated to operating performance and may adversely affect the market price of the Common Shares. As a result, an investor may be unable to sell any Common Shares such investor acquires at a desired price.

Potential future sales under Rule 144 may depress the market price for the Company’s Common Shares.

In general, under Rule 144, a person who has satisfied a minimum holding period of between 6 months and one-year and any other applicable requirements of Rule 144, may thereafter sell such shares publicly. A significant number of the Company’s currently issued and outstanding Common Shares held by existing shareholders, including officers and directors and other principal shareholders, are currently eligible for resale pursuant to and in accordance with the provisions of Rule 144. The possible future sale of the Company’s Common Shares by its existing shareholders, pursuant to and in accordance with the provisions of Rule 144, may have a depressive effect on the price of its Common Shares in the over-the-counter market.

The Company’s Common Shares are currently deemed a “penny stock”, which may make it more difficult for investors to sell their Common Shares.

The SEC has adopted regulations which generally define “penny stock” to be any equity security that has a market price less than $5.00 per Common Share or an exercise price of less than $5.00 per Common Share, subject to certain exceptions. The Company’s s securities are covered by the penny stock rules, which impose additional sales practice requirements on broker-dealers who sell to persons other than established customers and “accredited investors”. The term “accredited investor” refers generally to institutions with assets in excess of $5,000,000 or individuals with a net worth in excess of $1,000,000, exclusive of their principal residence, or annual income exceeding $200,000 or $300,000 jointly with their spouse. The penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document in a form prepared by the SEC which provides information about penny stocks and the nature and level of risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its salesperson in the transaction and monthly account statements showing the market value of each penny stock held in the customer’s account. The bid and offer quotations, and the broker-dealer and salesperson compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be given to the customer in writing before or with the customer’s confirmation. In addition, the penny stock rules require that prior to a transaction in a penny stock not otherwise exempt from these rules, the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction. These disclosure requirements may have the effect of reducing the level of trading activity in the secondary market for the stock that is subject to these penny stock rules. Consequently, these penny stock rules may affect the ability of broker-dealers to trade its securities. The Company believes that the penny stock rules may discourage investor interest in and limit the marketability of its Common Shares.

The Company has never paid dividends on its Common Shares.

The Company has not paid dividends on its Common Shares to date, and it does not expect to pay dividends for the foreseeable future. The Company intends to retain its initial earnings, if any, to finance its operations. Any future dividends on Common Shares will depend upon the Company’s earnings, its then-existing financial requirements, and other factors, and will be at the discretion of the Board.

FINRA has adopted sales practice requirements, which may also limit an investor’s ability to buy and sell the Company’s Common Shares.

In addition to the “penny stock” rules described above, FINRA has adopted rules that require that in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative low-priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA believes that there is a high probability that speculative low-priced securities will not be suitable for at least some customers. FINRA requirements make it more difficult for broker-dealers to recommend that their customers buy the Company’s Common Shares, which may limit an investor’s ability to buy and sell its stock and have an adverse effect on the market for the Common Shares.

Investors’ interests in the Company will be diluted and investors may suffer dilution in their net book value per share of Common Shares if the Company issues additional employee/director/consultant options or if the Company sells additional Common Shares and/or warrants to finance its operations.

In order to further expand the Company’s operations and meet its objectives, any additional growth and/or expanded exploration activity will likely need to be financed through sale of and issuance of additional Common Shares, including, but not limited to, raising funds to explore the Mine. Furthermore, to finance any acquisition activity, should that activity be properly approved, and depending on the outcome of its exploration programs, the Company likely will also need to issue additional Common Shares to finance future acquisitions, growth, and/or additional exploration programs of any or all of its projects or to acquire additional properties. The Company will also in the future grant some or all of its directors, officers, and key employees and/or consultants options to purchase Common Shares as non-cash incentives. The issuance of any equity securities could, and the issuance of any additional Common Shares will, cause the Company’s existing shareholders to experience dilution of their ownership interests.

If the Company issues additional Common Shares or decides to enter into joint ventures with other parties in order to raise financing through the sale of equity securities, investors’ interests in the Company will be diluted and investors may suffer dilution in their net book value per share of Common Shares depending on the price at which such securities are sold.

The issuance of additional shares of Common Shares may negatively impact the trading price of the Company’s securities.

The Company has issued Common Shares in the past and will continue to issue Common Shares to finance its activities in the future. In addition, newly issued or outstanding options, warrants, and broker warrants to purchase Common Shares may be exercised, resulting in the issuance of additional Common Shares. Any such issuance of additional Common Shares would result in dilution to the Company’s shareholders, and even the perception that such an issuance may occur could have a negative impact on the trading price of the Common Shares.

The Common Shares could be influenced by research and reports that industry or securities analyst may be published.

The trading market for the Common Shares could be influenced by research and reports that industry and/or securities analysts may publish about the Company, its business, the market or its competitors. The Company does not have any control over these analysts and cannot assure that such analysts will cover the Company or provide favorable coverage. If any of the analysts who may cover the Company’s business change their recommendation regarding the Company’s stock adversely, or provide more favorable relative recommendations about its competitors, the stock price would likely decline. If any analysts who may cover the Company’s business were to cease coverage or fail to regularly publish reports on the Company, it could lose visibility in the financial markets, which in turn could cause the stock price or trading volume to decline.

The Company is subject to the continued listing or trading criteria of the CSE and the OTCQB, and its failure to satisfy these criteria may result in delisting or removal of trading of its Common Shares from the CSE and the OTCQB.

The Company’s Common Shares are currently listed for trading on the CSE and quoted on the OTCQB. In order to maintain the listing on the CSE and the quotation on the OTCQB or any other securities exchange the Company may trade on, the Company must maintain certain financial and share distribution targets, including maintaining a minimum number of public shareholders. In addition to objective standards, these exchanges may delist the securities of any issuer if, in the exchange’s opinion: its financial condition and/or operating results appear unsatisfactory; if it appears that the extent of public distribution or the aggregate market value of the security has become so reduced as to make continued listing inadvisable; if the Company sells or disposes of its principal operating assets or ceases to be an operating company; if the Company fails to comply with the listing requirements; or if any other event occurs or any condition exists which, in their opinion, makes continued listing on the exchange inadvisable.

If the CSE, the OTCQB or any other exchange or quotation service were to delist or remove the trading of the Common Shares, investors may face material adverse consequences, including, but not limited to, a lack of trading market for the Common Shares, reduced liquidity, decreased analyst coverage, and/or an inability for the Company to obtain additional financing to fund its operations.

The Company faces risks related to compliance with corporate governance laws and financial reporting standards.

The Sarbanes-Oxley Act of 2002, as well as related new rules and regulations implemented by the SEC and the Public Company Accounting Oversight Board, require changes in the corporate governance practices and financial reporting standards for public companies. These laws, rules and regulations, including compliance with Section 404 of the Sarbanes-Oxley Act of 2002 relating to internal control over financial reporting, referred to as Section 404, materially increase the Company’s legal and financial compliance costs and make certain activities more time-consuming and burdensome.

metals between 1885 and 1981. The Bunker Hill Mine is located within Operable Unit 2 of the Bunker Hill Superfund site (EPA National Priorities Listing IDD048340921), where cleanup activities have been completed.

The Bunker Hill Mine

The Mine is one of the most storiedwell-known base metal and silver mines in American history. Initial discovery and development of the Bunker Hill Mine property began in 1885, and from that time until the mineMine closed in 1981 it produced over 35.8 million tons of ore at an average mined grade of 8.76% lead, 4.52 ounces per ton silver, and 3.67% zinc, which represented 162Moz of silver, 3.16M lbs. of lead and 1.35M lbs. of zinc (Bunker Limited Partnership,1985)Partnership, 1985). Throughout the long95-year operating history of the mine, there were over 40 different orebodies discovered and mined, primarily consisting of Zinc-Lead-Silverlead-silver-zinc mineralization. Although known for its significant lead and zinc production, 45-50% of the Net Smelter Value of its historical production came from its silver. The Bunker HillCompany and Sullivan Mining Company had a strong history of regular dividend payments to shareholders from the time the Company went public in 1905 until it was acquired in a hostile takeover by Gulf Resources in 1968.

When the mineMine first closed in 1981, it was estimated to still contain significant resources (Bunker Limited Partnership, 1985). The Mine and Smelter Complex were closed in 1981 when Gulf Resources was not able to continue to comply with new regulatory structures brought on by the passage of environmental statutes and as then enforced by the Environmental Protection Agency (the “EPA”).EPA. The Bunker Hill Lead Smelter, Electrolytic Zinc Plant and historic milling facilities were demolished about 25 years ago, and the area became part of the “National Priority List” for cleanup under EPA regulations, thereby pausing development of the Bunker Hill Mine for over 30 years.

The majority of the cleanup of the old smelter, zinc plant, and associated sites has now been completed and management believes the Mine is now poisedwell positioned for further development and an eventual return to production.  The

A more detailed description of the Mine can be found in the “Technical Report Summary” section of this report, including the current Mineral Resource Estimate, Mineral Reserves, an economic summary, property description and ownership, geology and mineralization, environmental studies and permitting, metallurgical testing, mining method, recovery methods, and current exploration and development.

Restart Project Activities

In early 2020, a new management team comprised of former executives from Barrick Gold Corp. assumed leadership of the Company. Since that time, the Company has been in contactconducted multiple exploration campaigns, published multiple economic studies and Mineral Resource Estimates, and advanced the rehabilitation and development of the Mine. In December 2021, it announced a project finance package with government officials who have expressed strong supportSprott Private Resource Streaming & Royalty Corp., an amended Settlement Agreement with the EPA, and cooperationthe purchase of the Bunker Hill Mine, setting the stage for a rapid restart of the Mine.

In January 2022, with the closing of the purchase of the Bunker Hill Mine, the funding of the $8,000,000 Royalty Convertible Debenture and $6,000,000 Series Convertible Debenture, and the announcement of an MOU for the purchase of the Pend Oreille process plant from a subsidiary of Teck Resources Limited, the Company effortsembarked on a program of activities with the goal of achieving a restart of the Mine. Key milestones and achievements from January 2022 onwards have included the closing of the purchase of the Pend Oreille process plant, the demobilization of the process plant to return the mineBunker Hill site, the completion of demolition activities at the Pend Oreille site, a Prefeasibility Study envisaging the restart of the Mine, and the completion of the primary portion of the ramp decline connecting the 5 and 6 Levels of the Bunker Hill Mine.

The following information does not purport to beingbe a productivecomplete summary of the Technical Report Summary, is subject to all the assumptions, qualifications and procedures set out in the Technical Report and is qualified in its entirety with reference to the full text of the Technical Report Summary. Each of the Qualified Persons of the Technical Report Summary is an independent qualified person under the definitions of §229.1300 (Item 1300 of Regulation S-K) (each a “Qualified Person”, and together the “Qualified Persons”) and have approved the summary of the Technical Report Summary below.

Summary

The Technical Report Summary describes the mining asset. and processing operations at the Company’s 100% owned Bunker Hill Mine located near the town of Kellogg, Idaho.

3

The Technical Report Summary considers a processing approach at Bunker where Pb, Ag and Zn mineralization is mined underground. Mineralized material will be conventionally milled and then concentrated by flotation of lead and silver (Pb/Ag) followed by flotation of zinc (Zn). Metal rich concentrates will then be sold to smelters in North America or overseas. Mill tailings will be deposited underground in the historic mining voids located throughout the Project.

Economic and Life of Mine highlights of the Technical Report Summary are listed in Table 1-3 and Table 1-4. Table 1-1 lists the Mineral Resource Estimate for the Bunker Hill Mine and Table 1-2 lists the Mineral Reserves for the Bunker Hill Mine. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves.

Mineral Resource Estimate

Geostatistics and estimates of mineralization were prepared by Resource Development Associates Inc. Industry accepted grade estimation techniques were used to develop global mineralization block models for the Newgard, Quill and UTZ zones. The Mineral Resource Estimate considers underground mining and mill processing as a basis for reasonable prospects of eventual economic extraction. The total Mineral Resource estimate for the Bunker Hill Mine is listed in Table 1-1 at a cutoff grade of NSR 70 $/ton. Mineral Resources are classified according to §229.1302(d)(1)(iii)(A) (Item 1302(d)(1)(iii)(A) of Regulation S-K).

(7) Totals may not add up due to rounding

(8) Mineral Resources are reported exclusive of Mineral Reserves. The reserves disclosed in the report represent measured mineral resources and indicated resources that were evaluated with modifying factors related to underground mining.

Mineral Reserves

Mineral Reserves have been estimated for the Quill, Newgard and UTZ sections of the Project. Measured and Indicated (M & I) Mineral Resources were converted to Probable Mineral Reserves for the mine. Measured Mineral Resources were converted to Probable Mineral Reserves because of uncertainties associated with modifying factors that were taken into account in the conversion from Mineral Resources to Mineral Reserves.

Measured and Indicated Resources were converted to Probable Mineral Reserves by evaluating operating cost, projected metal revenues and estimated stope shapes and geometries. The general widths, plunge and shape of the Quill and Newgard mineralization lends itself well to transverse (perpendicular to strike) long hole open stoping (LHOS) with fill utilizing rubber tire equipment. The UTZ deposit is more amenable to cut-and-fill (CF) methods due to its shape and geometry. Extraction of the planned mine shapes is assumed to be 100% of the NSR $80/ton plan. Breakeven NSR is $70/ton for LHOS and $75/ton for cut-and-fill stopes.

Mineral Reserves were classified in accordance with §229.1302(e)(2) (Item 1302(e)(2) of Regulation S-K). The mineral reserve statement is presented in Table 1-2. Mineral Reserves are estimated at an NSR value cutoff of $80/short ton at the reference point of saleable mill concentrates with an effective date of August 29, 2022.

Property Description and Ownership

The Bunker Hill lodeMine is located in NorthernShoshone County, Idaho with portions of the mine located within the cities of Kellogg and Wardner, Idaho in northwestern USA. The Kellogg Tunnel, which is the main access to the mine, is located at 47.53611°N latitude, 116.1381W longitude. The approximate elevation for the above cited coordinates is 2366 ft.

On December 15, 2021 BHMC signed a Purchase and Sale Agreement (PSA) with Placer Mining Corporation and both William and Shirley Pangburn to acquire full ownership of the subsequently listed mineral titles in addition to other Surface Rights and Real Property associated with land and structures of the Bunker Hill Mine.

On January 7, 2022, the Company closed the purchase of the Bunker Hill Mine. Mine assets were purchased for $7,700,000, with $300,000 of previous lease payments and a deposit of $2,000,000 applied to the purchase, resulting in cash paid at closing of approximately $5,400,000. The EPA obligation of $19,000,000 was discovered on September 9, 1885assumed by prospectors who had journeyed to IdahoBunker Hill as part of a gold rushthe acquisition.

Geology and Mineralization

The Northern Idaho Panhandle Region in the nearby Murray District. Early development was completed by Jim Wardner, a local mine developer who constructed the first milling facility.

In 1887 Simeon G. Reed purchased the claims and mill and incorporatedwhich the Bunker Hill Mine is located is underlain by the Middle Proterozoic-aged Belt-Purcell Supergroup of fine-grained, dominantly siliciclastic sedimentary rocks which extends from western Montana (locally named the Belt Supergroup) to southern British Columbia (locally named the Purcell Supergroup) and Sullivan Mining and Concentrating Company.is collectively over 23,000 feet in total stratigraphic thickness.

As the tonnage of ore in the mine increased, it became apparent that a mill of larger capacity was needed, and in 1891 a new mill of 400-ton capacity was built in the main valley below the confluence of Milo Creek with the South Fork of the Coeur d'Alene River. To transport ore to this mill, an aerial tramway with a horizontal length of 10,000 feet was constructed from Milo Gulch. This tramway served to transport all mine ore until the two-mile long Kellogg Tunnel was completed in 1902.

Two men stand out in the early history of the company. They are Frederick W. Bradley and Stanly A. Easton. Bradley first became associated with the company as a young engineer in 1890. In 1893 he was named general manager of the operation, and in 1897 he became the company's fourth president, a position he held until his death in 1933. He brought to Kellogg another young California engineer, Stanly Easton, who became general manager in 1903 and succeeded Bradley as President. Under the guidance of these two menMineralization at the Bunker Hill Company grew from a small mining and concentrating venture to a large, integrated mining and smelting operation with a national presence.

On May 25, 1917, Bunker Hill and Sullivan joined with the Hecla Mining Company in forming the Sullivan Mining Company, which purchased and operated the Star mine near Mullan, Idaho, approximately 15 miles to the east. The ore from the Star mine had a relatively high zinc content and necessitated the construction of an electrolytic zinc plant which was the first plant constructed of this type. The technological process that was devised for the plant was recognized as a significant new developmentMine is hosted almost exclusively in the metallurgical fieldUpper Revett formation of the Ravalli Group, a part of the Belt Supergroup of Middle Proterozoic-aged, fine-grained sediments. Geologic mapping and made possibleinterpretation progressed by leaps and bounds following the widespread userecognition of zinc in such applications as galvanizing.

From its early days and through two major world warsa predictable stratigraphic section at the Bunker Hill Company operatedMine and enabled the measurement of specific offsets across major faults, discussed in the following section. From an exploration and mining perspective, there were two critical conclusions from this research: all significant mineralized shoots are hosted in quartzite units where they are cut by vein structures, and the location of the quartzite units can be projected up and down section, and across fault offsets, to target extensions and offsets of known mineralized shoots and veins.

Mineralization at Bunker Hill Mine falls in four categories, described below from oldest to youngest events:

Bluebird Veins (BB): W—NW striking, SW-dipping, variable ratio of sphalerite-pyrite-siderite mineralization. Thick, tabular cores with gradational margins bleeding out along bedding and fractures.

Stringer/Disseminated Zones: Disseminated, fracture controlled and bedding controlled blebs and stringer mineralization associated with Bluebird Structures, commonly as an independenthalos to vein-like bodies or as isolated areas where brecciated quartzite beds are intersected by the W-NW structure and well-knownfold fabrics.

Galena-Quartz Veins (GQ): E to NE striking, S to SE dipping, quartz-argentiferous galena +/-siderite-sphalerite-chalcopyrite-tetrahedrite veins, sinuous-planar with sharp margins, cross-cut Bluebird Veins.

Hybrid Zones: Formed at intersections where GQ veins cut BB veins, with open space deposition of sulfides and quartz in the vein refraction in quartzite beds, and replacement of siderite in the BB vein structure by argentiferous galena from the GQ Vein.

Environmental Studies and Permitting

Because the mine is on patented mining claims (privately-owned land), only a limited number of permits are required for mining and smelting companymilling operations. These relate to: (1) air quality and was listed onemissions from crushing, milling and processing and (2) any refurbishment of surface buildings that may require construction permits.

Section 9, Paragraph 33 of that agreement stipulates that BHMC must obtain a National Pollutant Discharge Elimination System (“NPDES”) permit for effluent discharged by Bunker Hill Mine by May 14, 2023. This obligation exists and the deadline will occur at a point in time where restart activities are planned to occur.

BHMC will initiate a voluntary Environmental, Social and Health Impact Assessment (“ESHIA”) for the activities described in the 1970s compelled Bunker HillTechnical Report Summary and for its business model as a whole. This study is projected for completion in 2024 and will conform to spend large sumsISO, IFC and GRI standards.

Metallurgical Testing

Resource Development Inc. (Rdi) initiated metallurgical test work on plant improvements in order to complythree samples designated Newgard, Quill and Utz with newly enacted federal air and water pollution laws. The Company also made major efforts to reclaim surrounding hillsides which had been denuded by the effectsprimary objective of decades of airborne smelter effluents and timbering for mining purposes.

Flotation testing was completed through locked-cycle testing, the results of 1981 with resulting declineswhich are displayed in metal prices led to Gulf Resources' decisiontable 1-5

Table 1-5 Summary of Locked-Cycle Flotation Test Results

The open-cycle and locked-cycle tests were completed at a primary grind of P₈₀ 270 mesh for rougher flotation. Rougher scavenger flotation was included in August 1981 to close its Bunker Hill operations and put the company up for sale. In 1982 the company was sold to the Bunker Limited Partnership (“BLP”) whose principal owners were Harry Magnuson, Duane Hagadone, Jack Kendrick and Simplot Development Company (the Simplot company dropped out of the partnership in 1987). Although the new company ultimately reopened the mine,both the lead and zinc smeltingcircuits to increase the amount of value sent to the cleaner stages. Regrind of the lead rougher concentrate with a pebble mill was completed to a particle size of approximately P₈₀ 400 mesh for cleaner flotation. No regrind was completed with the zinc rougher concentrate.

BHMC has contracted SGS Canada Inc (SGS) to conduct a metallurgical study to further evaluate and refiningoptimize metal recovery for the Bunker Hill Project. The primary objective of the test program is to complete metallurgical test work to improve met results over the Pre-feasibility Study (PFS) performed by Rdi for the Bunker Hill Project.

Mining Method

Long-hole stoping with fill (LHOS), cut-and-fill and possibly room-and-pillar mining with fill are the only methods viable for sustained operations remained closed.today. LHOS is the preferred mining method with limited cut-and-fill mining at Bunker Hill Mine. Room-and-pillar mining is not in the current plan. Timbered ground support has been replaced with newer ground support technology of rock bolts, mesh, shotcrete and steel sets as required.

As noted,

Beginning in October of 2021 and completed in April of 2022, BHMC conducted a geotechnical investigation of the underground conditions at the Bunker Hill Mine. Data collection involved a data analysis of RQD values logged with previous exploration drilling, geotechnical logging of recently drilled rock cores and an extensive investigation of pre-existing underground excavations and development. Ground conditions are generally good to excellent at Bunker Hill Mine and the rest of the mines in the Silver Valley. Bunker Hill Mine does not have a history of rock burst events that are frequent in the deeper mines to the east.

Recovery Methods

Bunker Hill plans to re-construct a crush-grind-flotation-concentration mill from the nearby Pend Oreille (PO) mine was briefly reopened from 1988 to 1990 by BLP. This reopening resulted in northern Washington on the Bunker Hill Kellogg Mine Yard. There currently is a large effort being madebuilding that housed the historic machine shop at the Bunker Hill mine that will first need to drillbe dismantled and define the zinc-rich Quill ore body and to expand and improve the ramp systemremoved for modern rubber-tired mining methods. Although exceptional progress was made in defining new mineralization and in meeting other goals, the operations were underfunded and targeted production goals were not met. Combined with low metal prices dueaccess to the recessionexisting slab. The future structures to house the grind-flotation-concentration circuit, as well as the secondary crushing circuit and concentrate storage facilities will need to be constructed.

The process consists of the early 1990s, BLP closed the mine in January, 1991a primary and shortly thereafter filed for bankruptcy. On May 1, 1992,secondary ore crushing circuit, then a primary grinding circuit followed by two separate flotation circuits to recover lead, zinc, silver and gold into two separate concentrate products; a lead, silver, gold concentrate and a zinc concentrate. Approximately 648,000, short tons of ore will be processed a year at a rate of 1,800 stpd, or 79 stph at 95% availability.

Current Exploration and Development

Bunker Hill has a rare exploration opportunity available at the Bunker Hill Mine and has embarked on a new path to fully maximize the potential. A treasure trove of geologic and production data has been organized and preserved in good condition in the mine office since the shutdown of major mine operations in the early 1980s. This data represents 70+ years of proper scientific data and sample collection, with high standards of accuracy and precision that were generally at or above industry standards at the time.

Geology and Mineralization

Geology

The Coeur d’Alene Mining District is one of the most prolific mining districts in North America. It has been in constant production since its discovery in the 1880s, historically is the second largest silver-producing area in the world, and is one of the largest zinc and lead producers as well. Over 100 mines historically have reached commercial production in the District and currently hosts two major mines, the Lucky Friday/Gold Hunter owned by Hecla Mining Company, and the Galena Mine, owned by America’s Silver. A number of other mines including the Sunshine, the Crescent, and the Coeur Mine have the potential to be re-started should silver prices rise sufficiently to justify reactivation.

The District is underlain by members of the Precambrian Belt Super Group. The metasedimentary rocks are predominantly fine-grained quartzite, siltites and argillites. The District is structurally complex with multiple folding and faulting events being evident.  The WNW-trending Osburn fault runs through the district and has about 15 miles of right lateral displacement.

Mineralized zones in the district are generally parallel to sub-parallel to the Osburn fault. Numerous mines, including the Bunker Hill, are located south of the Osburn fault and occupy the steeply dipping to overturned north limb of a WNW-trending fold.

Mineralization

The mineralization at Bunker Hill is hosted in localized, structurally controlled shear zones and strati-form zones of significant width. The mineral bodies are grouped into three different types.

The NW trending Bluebird mineral zones are zinc rich and consist of sphalerite in excess of galena with variable amount of pyrite in a gangue of greyish quartz and minor siderite. This mineralized material is commonly localized in smaller parasitic folds, broken by reverse shears (Meyer, 1982).

The Jersey type mineral bodies consist principally of veins containing galena with lesser amounts of sphalerite, chalcopyrite and tetrahedrite (Meyer, 1981).  These NE to N trending veins are referred to as “link” veins as they extend between the NW trending Cate and Dull faults, or other faults in the mine. Gangue minerals are primarily white quartz with lesser siderite.

“Hybrid” mineral bodies comprise the third type and are associated with zones of brecciation located at the junctions of major faults. These are multi-stage systems where “Bluebird” type fracture zones were reopened and brecciated prior to flooding by galena from the newly opened ‘link’ veins. The galena penetrated and partially replaced the previous minerals and filled remaining open spaces (Meyer, 1981).

Mine and Mill Operations

Starting with the original Bunker Hill and Sullivan claims, the Bunker Hill Mine eventually encompassed 620 patented mining claims totaling 6,200 acres. From the discovery cuts some 3600 feet above sea level, over 20 major ore zones were mined to nearly 1600 feet below sea level, a vertical distance of about one mile.

Four major mining methods were historically employed in the Bunker Hill Mine. The oldest is square set or cut and fill. These methods employ support of the stope where the vein is mined with sets of timbers and/or rock bolts, and then sand-fill is pumped from the surface as the mining activity moves to a higher elevation. The broken ore was scraped into chutes by compressed air powered slushers and dropped into ore pockets on the level below.

The second method called shrink stoping is similar to the above, but no ground support is required. Instead the broken ore is used as both ground support and a mining floor and the full mining cut is completed prior to withdrawing the ore from the stope. Air powered slushers or compressed air operated mucking machines on rubber tires were historically used.

A third mining method is known as room and pillar mining. In this operation, no timber is required but pillars of ore are left in place as supports until the stoping moves to a higher elevation, at which time sand fill is pumped in to provide the floor for the next cut. As the ore is broken, rubber tired, compressed air operated mucking machines picked it up putting it into a box on the back of the loader. It was then transported to a chute in the stope where it dropped into the ore pocket on a lower level.

The fourth method is sublevel blasthole stoping. Diesel powered equipment cuts horizontal slices every forty feet in the ore zones. Then long holes are drilled in the pillars between horizontal slices. The holes are blasted allowing the ore to fall to the bottom slice and scooped up by diesel powered loaders and transported to ore passes. This method was used above the Kellogg Tunnel, and ore was transported by gravity to the tunnel and hauled out by train to the surface.

From the ore pockets on the various levels of the mine below the Kellogg Tunnel, ore trains powered by battery driven locomotives transported the ore to ore pockets located at the shaft. In the shaft, large steel buckets, called skips, were loaded and hoisted to the Kellogg Tunnel level where the ore was dumped into two large concrete bins. Drawn from these storage areas by gravity, the ore was next transported two miles to the surface in 22-car ore trains pulled by trolley and diesel locomotives.

Blasthole stoping, cut and fill, and shrinkage stoping methods are likely to be employed in the restart of the Bunker Hill Mine. mine can reasonably be expected to generate a positive return on investment with an after-tax IRR of 36% based on the reserves presented. It is reasonable to expect the conversion of Inferred resources to Indicated resources and indicated resources to measured resources to continue. Inferred Mineral Resources are considered too geologically speculative to have economic considerations applied to them to be classified as a Mineral Reserve.

The main improvementTechnical Report Summary is based on all available technical and productivity gain over historic operations will be the widespread usescientific data available as of rubber-tired equipment, which will be used for mucking and transport of the broken mineralized material. The upper part of the mine is largely already developed with ramps, which will be usedAugust 29, 2022. Mineral Resources are considered by the Company for rubber-tired access. MostQP to meet the reasonable prospects of these ramps were completed by the Bunker Hill Companyeventual economic extraction due two main factors; 1) cut-off grades are based on scientific data and ramp expansion also occurred during the Bunker Limited Partnership mine reopening.

Company engineers have already inspected many portions of the ramp system in the upper part of the mine and the ramps are generally in very good shape and will only require minor repair and clean-up.

An existing water treatment plant which was originally built by the Bunker Hill Company remains in operation and is operated by the United States Environmental Protection Agency (the “E.P.A.”) through a local contractor. This plant has received numerous upgrades and capacity improvements in the last twenty-five years. All mine water which is discharged from the Bunker Hill Mine has been treated by the E.P.A. during the ownership of the mine by Placer Mining.

Completed Work and Future Plan of Operations

The Company has undertaken a due diligence program to assure itself of the viability of a restart of the Bunker Hill Mine. This necessitated an extensive review of the records that were present primarily at the Bunker Hill Mine offices. At those offices there are tens of thousands of pages of reports and records which detail the operations of the mine from its earliest days to the time of the shutdown in 1991 by BLP.

In addition to reports, there are several thousand historical maps of all scales and sizes as well as historical mineral diagrams which detail the mineral bodies that remained in the mine at the time of closure in January, 1991. These reports are not compliant with Canada National Instrument 43-101 and cannot be used for the purposes of establishing reserves pursuant to that standard.

The Company has satisfied itself that there is a large amount of remaining zinc/lead/silver mineralization in numerous zones within the Bunker Hill Mine. The Company is now developing a plan to bring a number of these zones into N.I. 43-101 compliance through new sampling and drilling programs. The Company has identified several zones as having highest priority. The Company has prioritized zones capable of providing production in the near term, these being the UTZ Zone, the Newgard Zone and the Quill Zone. These three mineral zones will be the first to be N.I. 43-101 verified and will provide the majority of the early feed upon mine start-up.

The Bunker Hill Mine main level is termed the nine level and is the largest level in the mine and is connected to the surface by the approximately 12,000 foot-long Kellogg Tunnel. Three major inclined shafts with associated hoists and hoistrooms are located on the nine level. These are the No. 1 shaft, which is used for primary muck hoisting in the main part of the mine; the No. 2 shaft, which is a primary shaft for men and materials in the main part of the mine; and the No. 3 Shaft, which is used for men, materials and muck hoisting for development in the northwest part of the mine.

The top stations of these shafts and the associated hoistrooms and equipment have all been examined by Company personnel and are in moderately good condition. The Company believes that all three shafts remain in a condition that they are repairable and can be bought back into good working order over the next few years.

The water level in the mine is held at approximately the ten level of the mine, roughly 200 feet below the nine level. The mine was historically developed to the 27 level, although the 25 level was the last major level that underwent significant development and past mining. Each level is approximately 200 feet vertically apart.

The southeastern part of the mine was historically serviced by the Cherry Raise, which consisted of a two-compartment shaft with double drum hoisting capability that ran at an incline up from the nine level to the four level. The central part of the mine was serviced upward by the Last Chance Shaft from the nine level to the historic three or four level. Neither the Cherry Raise or the Last Chance shaft are serviceable at this time. However, the upper part of the mine from eight level up to the four level has been developed by past operators by a thorough-going rubber tire ramp system, which is judged to be about 65% complete.

The Company has already repaired the first several thousand feet of the Russell Tunnel, which is a large rubber tire capable tunnel with an entry point at the head of Milo Gulch. This tunnel will provide early access to the UTZ Zone. The Company has inspected a great deal of the ramp system between the eight level and the four level, and the ramps are in good shape with only minor repair and rehabilitation needed. The Company has made development plans to provide interconnectivity of the ramp system from the Russell Tunnel at the four level down to the eight level, with further plans to extend the ramp down to the nine level. Thus rubber-tired equipment will be used for mining and haulage throughout the upper mine mineral zones, which have already been identified, and for newly found zones.

The Kellogg Tunnel will be used as a tracked rail haulage tunnel for supply of men and materials into the mine and for haulage of mined material out of the mine. Historically the Kellogg Tunnel (or “KT” for short) was used in this manner when the mine was producing upwards of 3000 tons per day of mined material. The Company has inspected the KT for its entire length and has determined that significant timbered sections of the tunnel will need extensive repairs. These are areas that intersect various faults passing through the KT at normal to oblique angles and create unstable ground.

The Company has also determined that all of the track, as well as spikes, plates and ties holding the track will need to be replaced. Additionally, the water ditch that runs parallel to the track will need to be thoroughly cleaned out and new timber supports and boards that keep the water contained in its path will need to be installed. All new water lines, compressed air lines and electric power feeds will also need to be installed. The total cost estimate for this KT work is still in process at the time of the date of this report, but the time estimate for these repairs is approximately eighteen months.

It is anticipated that earliest production will come from the upper levels of the mine where company personnel have observed mining faces of mineralized material that are readily mineable, as they were left behind by past operators in a more or less fully developed state.

The Company anticipates constructing its own milling facility near the mouth of the Kellogg Tunnel. Initially the mill capacity will be 1500 tons per day, and the mill will be designed for ready expansion when needed.

The Company has identified multiple tailings disposal sites to the west-northwest of where the mill will be located.

As noted above, the EPA for several decades has provided mine water treatment services for the Bunker Hill Mine. When the Company begins its lease of the mine, it is planned that the EPA will be providing water treatment services under contract with the Company and such services will continue for at least five years or more. Although no firm agreement has yet been reached, recent discussions with the EPA also indicate that overflows from the mill or decant from the tailings facilities could also be treated at the water treatment plant under the same treatment contract.

If all of the mine water, mill outflows, and tailings discharges can be treated by the EPA treatment plant as currently contemplated, the Company will be initially relieved of the need to obtain a water discharge permit. Upon initiating mine production from the UTZ, Newgard, and Quill zones at rates of approximately 1500 tons per day, the Company would anticipate mining approximately 540,000 tons per year of material. The three aforementioned zones are believed to have sufficient mineral to supply the Company mining needs for approximately 8 years.

Once the repairs are completed to the Kellogg Tunnel, mineralized material haulage will be able to immediately occur out of this tunnel, which will enhance the production capabilities of the mine by several magnitudes. Some mineralized material will continue to be transported by rubber-tired equipment directly out the Russel Tunnel, but the majority of mineralized material will be dropped down existing internal passes and be hauled out of the KT on rail. By this time in the restart program the Company would expect to be in production at around 1500 tons per day, which is approximately the planned mill capacity. If all items proceed as planned, the Company believes a steady state production of 1500 tons per day is achievable in approximately 36 months from the time of takeover of operations.

Additionally, once the KT repairs are completed, work on the repairs of the shafts and hoists can proceed with greater speed and the lower levels of the mine can be dewatered. The shaft work and pumping should commence at about year two of mine operations.

Numerous other past-producing mineral bodies will begin to be revealed as the water levels are lowered and the mine is drained to the fullest. Some of these mineral bodies are lead-silver rich zones such as the Emery, Shea, Veral and the “J”, while others will add more material containing zinc such as the Tallon, Rosco, or Tony, while still others are best described as polymetallic such as the New Landers or the Francis.

The Company geologists and engineering personnel have studied the past records thoroughly and conclude that very good exploration and discovery potential exists at depth on downward rakes of known structures. Strata-bound zones such as the Newgard, Quill and Tallon await drilling to the west, while both the southeast and northwest limits of the main original Bunker Hill structure, in the heart of the Cate/Dull fault system, still remain viable as targets for future discovery of new mineral bodies or extensions of past mined structures.

Technical Report

On September 6, 2018, the Company filed on SEDAR a National Instrument 43-101 (“NI 43-101”) technical report on its Bunker Hill property.

The technical report included:

1.A 10-12 million ton Exploration Target comprised of the Quill/Newgard zones.  For comparison purposes, the historical resource estimate for the whole Bunker Hill property is 9.1 million tons grading 5.08% Zn, 2.35% Pb and 40 g/t Ag (or 1.29 ounces per ton); 

2.Results of Independent Sampling showing grades for the Quill/Newgard zones (Levels 9 & 10) averaging 20% Zn, 14%

Pb and 247 g/t Ag (or 7.90 ounces per ton), which exceed average historic grades; and

3.a Plan for a US$7.7 million Exploration Program to upgrade the historic resources to a NI 43-101 Indicated Resource. 

Additionally, as noted, the Company currently has in its possession, and has had access to, numerous historical technical reports that were completedaccessible in the past by highly qualified parties.mining operations as well as by using generally accepted mining and processing costs that are similar to many projects in Idaho.

Recommendations

Continued analysis and interpretation of the geophysical survey results should aid to guide future exploration activities outside of historical mine working areas. Additional exploration drilling with the advancement of underground mine development is also advised due to the proximity of future development to under-explored areas of historical workings. Continued digitization and interpretation of historical mapping and research will aid to guide future underground and surface exploration activities.

Completion of issued for construction (IFC) level drawings for the mineral processing facilities is recommended.

Completion of IFC level engineering drawings related to the paste backfill plant are recommended. Final tails product material generated from additional metallurgical testing will work to optimize binder compositions and have the potential to reduce backfill OPEX costs.

Additional geotechnical studies are recommended with the advancement of underground development. Continued geotechnical diamond drilling associated with future resource delineation and exploration drilling activities will provide a better sample set for rock strength testing and geotechnical logging. Future underground development will also allow for the investigation of previously mined areas and association of historical span allowances based on previous ground support methods.

Additional resource delineation and conversion drilling and mine block modeling should continue to increase the conversion of Inferred to Indicated Resources.
