Nature and Continuance of Operations Bunker Hill Mining Corp. (“we”, “us”, “Bunker Hill”, or the “Company”) was incorporated under the laws of the state of Nevada, U.S.A. on February 20, 2007, under the name Lincoln Mining Corp. Pursuant to a Certificate of Amendment dated February 11, 2010, the Company changed its name to Liberty Silver Corp., and on September 29, 2017, the Company changed its name to Bunker Hill Mining Corp. The Company’s registered office is located at 1802 N. Carson Street, Suite 212, Carson City, Nevada 89701, and its Canadian office is located at 300-1055 West Hastings Street, Vancouver, British Columbia, Canada, V6E 2E9. As of the date of this Form 10-Q, the Company had one subsidiary, Silver Valley Metals Corp. (“Silver Valley”, formerly American Zinc Corp.), an Idaho corporation created to facilitate the work being conducted at the Bunker Hill Mine in Kellogg, Idaho (“Bunker Hill Mine”). The Company was incorporated for the purpose of engaging in mineral exploration, and exploitation activities, and is currently focused on the development and planned operations of the Bunker Hill Mine. Bunker Hill holds a 100 % interest in the historic Bunker Hill Mine located in the town of Kellogg, Idaho. The Bunker Hill Mine previously operated between 1885 and 1981 producing over 165 million ounces of silver and 5 million tons of base metals during that time. We are currently focused on the construction of the Bunker Hill Mine mill facilities and upgrades to the Bunker Hill Mine historic underground infrastructure as well as further delineating the mine’s mineral resources. 2. Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed interim consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the U.S. and the rules and regulations of the U.S. Securities and Exchange Commission for interim financial information. Accordingly, they do not include all the information and footnotes necessary for a comprehensive presentation of financial position, results of operations, shareholders’ deficiency, or cash flows. It is management’s opinion, however, that all material adjustments (consisting of normal recurring adjustments) have been made which are necessary for a fair financial statement presentation. The unaudited condensed interim consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K, which contains the annual audited consolidated financial statements and notes thereto, together with the Management’s Discussion and Analysis, for the year ended December 31, 2025. The interim results for the period ended March 31, 2026 are not necessarily indicative of the results for the full fiscal year. The unaudited condensed interim consolidated financial statements are presented in United States dollars, which is the Company’s functional currency. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes for items such as mineral reserves, useful lives and depreciation methods, potential impairment of long-lived assets, sale of mineral properties for the accounting of the conversion of the royalty convertible debenture (the “RCD”), deferred income taxes, settlement pricing of commodity sales, fair value of stock based compensation, accrued liabilities, estimation of asset retirement obligations and reclamation liabilities, convertible debentures, stream obligation, and warrants. Estimates are based on historical experience and various other assumptions that the Company believes to be reasonable. Actual results could differ from those estimates. 3.

Included in long-term deposit is a down payment for additional mining-related mobile equipment which the Company intends to lease from Caterpillar Inc. 5. Mill Facilities On May 13, 2022, the Company purchased a comprehensive package of equipment and parts inventory from Teck Resources Limited (“Teck”) a related party as of June 5, 2025 (note 15). The package comprised substantially all processing equipment of value located at the Pend Oreille mine site, including complete crushing, grinding and flotation circuits suitable for a planned ~1,500 ton-per-day operation at the Bunker Hill site, and total inventory of nearly 10,000 components and parts for mill, assay lab, conveyer, field instruments, and electrical spares. The process plant was purchased in an assembled state in the seller’s location, and included major processing systems, significant components, and a large inventory of spare parts. The Company has disassembled it, transported it to the Bunker Hill site, and reassembled it. The Company determined that the transaction would be accounted for as an asset acquisition, with the process plant representing a single asset, with the exception of the inventory of spare parts, which has been separated out on the condensed interim consolidated balance sheets as a non-current asset. As the plant was demobilized, transported and reassembled, installation and other costs associated with these activities were captured and capitalized as components of the asset.

A sale of mineral properties of $ 1,324,199 corresponding to the issuance of the royalty was recognized on the interim consolidated balance sheets. On January 17, 2025, as consideration for Sprott advancing the debt facility, as described in note 9, the Company granted a royalty for 0.5 % of life-of-mine gross revenue from mining claims considered to be historically worked, contiguous to current accessible underground development, and covered by the Company’s 2021 ground geophysical survey. A 0.35 % rate will apply to claims outside of these areas. On June 5, 2025, the 0.5 % royalty was amended to apply to both primary and secondary claims comprising the Project. A sale of mineral properties of $ 383,789 corresponding to the issuance of the royalty on the interim consolidated balance sheets.

These Sprott transactions were treated as a sale of mineral interest. The portion of the mineral interest sold was determined based on an analysis of discounted life-of-mine royalty payments relative to discounted future cash flows generated from the mine net of capital and operating costs, applied to the carrying value of the Bunker Hill Mine as of above funding dates, before consideration of the sale of mineral properties. This analysis utilized a discount rate of 15% and long-term metal prices of $1.20/lb, $0.95/lb and $27.29/oz for zinc, lead and silver respectively. 11 7.

Pursuant to the terms of the Amended Settlement, upon purchase of the Bunker Hill Mine and the satisfaction of financial assurance commitments (as described below), the $ 19,000,000 of cost recovery liabilities were to be paid by the Company to the EPA on the following dates: Schedule of Amended Settlement Environmental Protection Agency Agreement Date Amount Within 30 days of Settlement Agreement $ 2,000,000 November 1, 2024 $ 3,000,000 November 1, 2025 $ 3,000,000 November 1, 2026 $ 3,000,000 November 1, 2027 $ 3,000,000 November 1, 2028 $ 3,000,000 November 1, 2029 $ 2,000,000 plus accrued interest In addition to the changes in payment terms and schedule, the Amended Settlement includes a commitment by the Company to secure financial assurance for the principle outstanding in the form of performance bonds or letters of credit deemed acceptable to the EPA. The financial assurance can be drawn on by the EPA in the event of non-performance by the Company of its payment obligations under the Amended Settlement (the “Financial Assurance”). The amount of the bonds will decrease over time as individual payments are made. During the year ended December 31, 2024, the Company made a $ 3,000,000 payment to the EPA bringing the principal of the cost recovery liability to $ 14,000,000 as of December 31, 2025 and March 31, 2026. As of March 31, 2026, and December 31, 2025, the Company had two payment bonds of $ 9,999,000 and $ 4,001,000 in place to secure this liability. The collateral for the payment bonds is comprised of restricted cash of $ 2,975,000 for March 31, 2026 and December 31, 2025 shown within current assets and land pledged by third parties, with whom the Company has entered into an agreement that contemplates a monthly fee of $ 20,000 (payable in cash or common stock of the Company, at the Company’s election) the “Financing Cooperation Agreement”. In the fourth quarter of 2025 the EPA agreed to forebear enforcement of any late payments pursuant to the first amendment of the Amended Settlement Agreement to facilitate ongoing discussion of a potential second amendment to the Amended Settlement Agreement, including the payment due in November 2025. The EPA reserved all rights to resume collection of late payments in the event a Second Amendment of the 2021 Amended Settlement Agreement is not finalized. 12 The Company recorded accretion expense on the liability of $ 344,163 and $ 408,013 for the three months ended March 31, 2026 and March 31, 2025, respectively, bringing the net liability to $ 10,658,707 (previously accrued interest of $ 156,743 ) as of March 31, 2026. Water Treatment Charges – Idaho Department of Environmental Quality (“IDEQ”) Separate to the cost recovery liability pursuant to the EPA Settlement Agreement, the Company has agreed to pay ongoing water treatment charges. The Company is currently charged a monthly amount of $ 100,000 by the IDEQ as instalments toward the cost of treating water at the CTP. Upon receipt of an invoice from the IDEQ for actual CTP costs incurred, a reconciliation is performed relative to payments made, with an additional amount due or refund received as applicable. 9. Promissory Notes Payable, Convertible Debentures, and Silver Loan $6,000,000 Convertible Debenture (“CD1”) CD1 bore interest at an annual rate of 7.5 %, payable in cash or shares at the Company’s option on principal of $ 6,000,000 . The CD1 is secured by a pledge of the Company’s properties and assets. In August 2024, the Company and Sprott agreed to amend the maturity date of CD1 from March 31, 2026, to March 31, 2028, and that CD1 would remain outstanding until the new maturity date unless the Company elects to exercise its option of early repayment. The Company determined that the amendments to the terms of the CD1 should not be treated as an extinguishment of the CD1 and have therefore been accounted for as a modification. The CD1 was convertible into Common Shares at a price of Canadian Dollars (“C$”) C$ 10.50 per Common Share, subject to stock exchange approval. In June 2025, the Company and Sprott agreed to amend the rate of interest of CD1 reducing it from 7.5 % to 5.0 % per annum, and the current conversion price, being the U.S. dollar equivalent of C$ 10.50 per Common Share, was reduced to $ 3.675 . The Company determined that the amendments to the terms of the CD1 should be treated as an extinguishment of the CD1. The new debt was bifurcated between host debt and the conversion option valued at $ 3,912,661 (net of transaction costs of $ 52,161 ) and $ 1,928,753 respectively, as of June 5, 2025. The debt and the conversion option were fair valued using a binomial lattice methodology based on a modified Cox-Ross-Rubenstein (“CRR”) approach. $15,000,000 Series 2 Convertible Debenture (“CD2”) CD2 bore interest at an annual rate of 10.5 %, payable in cash or shares at the Company’s option on principal of $ 15,000,000 . CD2 is secured by a pledge of the Company’s properties and assets. In August 2024, the Company and Sprott agreed to amend the maturity date of CD2 from March 31, 2026, to March 31, 2029 , and that CD2 would remain outstanding until the new maturity date unless the Company elects to exercise its option of early repayment. The Company determined that the amendments to the terms of the CD2 should not be treated as an extinguishment of the CD2 and have therefore been accounted for as a modification. In June 2025, the Company and Sprott agreed to amend the rate of interest of CD2 reducing it from 10.5 % to 5.0 % per annum, and the current conversion price, being the U.S. dollar equivalent of C$ 10.15 per Common Share, was reduced to $ 3.675 . The Company determined that the amendments to the terms of the CD2 should be treated as an extinguishment of the CD2. The new debt was bifurcated between host debt and the conversion option valued at $ 8,164,765 (net of transaction costs of $ 130,401 ) and $ 6,482,376 respectively, as of June 5, 2025. The debt and the conversion option were fair valued using a binomial lattice methodology based on a modified CRR approach. Prior to the extinguishment on June 5, 2025, the Company determined that in accordance with ASC 815 Derivatives and Hedging, each debenture will be valued and recorded as a single instrument, with the periodic changes to fair value accounted through earnings, profit and loss. 13 The gain (loss) on changes in fair value of convertible debentures recognized on the condensed interim consolidated statements of income (loss) and comprehensive income (loss) during the three months ended March 31, 2026 and March 31, 2025, was $ nil and $ 78,364 , respectively. The portion of changes in fair value that is attributable to changes in the Company’s credit risk is accounted for within other comprehensive income. During the three ended March 31, 2026, and March 31, 2025, the Company recognized $ nil and $ 540,898 respectively, within other comprehensive income. Interest expense on the pre-extinguished CD1 and CD2 for the three months ended March 31, 2025 was $ 499,315 . The Company recorded accretion expense on host debt of CD1 of $ 154,259 and $ nil for the three months ended March 31, 2026 and March 31, 2025 respectively, bringing the net liability to $ 4,395,869 as of March 31, 2026. The Company recorded accretion expense on host debt of CD2 of $ 324,130 and $ nil for the three months ended March 31, 2026 and March 31, 2025 respectively, bringing the net liability to $ 9,176,141 as of March 31, 2026. At March 31, 2026 interest of $ 262,500 ($ 268,333 at December 31, 2025) is included in interest payable on the condensed interim consolidated balance sheets. For the three months ended March 31, 2026, and March 31, 2025, the Company recognized $ 9,800 and $( 284,741 ), respectively, gain (loss) on debt settlement on the condensed interim consolidated statements of income (loss) and comprehensive income (loss) as a result of settling interest by issuance of shares. $4,000,000 Series 3 Convertible Debenture (“CD3”) The Company closed the $ 4,000,000 CD3 on June 5, 2025 (note 15). CD3 bears interest at an annual rate of 5.0 %, payable in cash or shares at the Company’s option, and matures on June 5, 2030 . CD3 is secured by a pledge of the Company’s properties and assets and CD3 is convertible into Common Shares at a price of $ 0.105 per Common Share, subject to the stock exchange approval. The new debt was bifurcated between host debt and the conversion option valued at $ 2,268,397 (net of transaction costs of $ 174,576 ) and $ 1,558,941 respectively, as of June 5, 2025. The debt and the conversion option were fair valued using a binomial lattice methodology based on a modified CRR approach. The Company recorded accretion expense on host debt of CD3 of $ 122,112 and $ nil for the three months ended March 31, 2026 and March 31, 2025, bringing the net liability to $ 2,644,820 as of March 31, 2026. At March 31, 2026, interest of $ nil ($ nil at December 31, 2025) is included in interest payable on the condensed interim consolidated balance sheets. The Company performs quarterly testing of the covenants in the CD1, CD2, CD3 and was in compliance with all such covenants as of March 31, 2026. The Stream On June 23, 2023, all conditions were met for the closing of the Stream, and $ 46,000,000 was advanced to the Company. The Stream was secured by the same security package that is in place with respect to the RCD, CD1, and CD2. The Stream was repayable by applying 10% of all payable metals sold until a minimum quantity of metal is delivered consisting of, individually, 63.5 million pounds of zinc, 40.4 million pounds of lead, and 1.2 million ounces of silver (subsequently amended, as described below). Thereafter, the Stream was repayable by applying 2% of payable metals sold. The delivery price of streamed metals was 20% of the applicable spot price. The Company incurred $ 740,956 of transactions costs directly related to the Stream which were capitalized against the initial recognition of the Stream. The Company determined that in accordance with ASC 815 derivatives and hedging, the Stream does not meet the criteria for treatment as a derivate instrument as the quantities of metal to be sold thereunder are not subject to a minimum quantity, and therefore a notional amount is not determinable. The Company has therefore determined that in accordance with ASC 470, the stream obligation should be treated as a liability based on the indexed debt rules thereunder. The initial recognition has been made at fair value based on cash received, net of transaction costs, and the discount rate calibrated so that the future cash flows associated with the Stream, using forward commodity prices, equal the cash received. The measurement of the stream obligation is accounted for at amortized cost with accretion at the discount rate. Subsequent changes to the expected cash flows associated with the Stream will result in the adjustment of the carrying value of the stream obligation using the same discount rate, with changes to the carrying value recognized in the condensed interim consolidated statements of income (loss) and comprehensive income (loss). 14 The Company determined the effective interest rate of the Stream obligation to be 10.6 % and recorded accretion expense on the liability of $ nil and $ 945,295 for the three months ended March 31, 2026 and March 31, 2025 respectively recognized in the consolidated statement of (loss) and comprehensive (loss), accretion expense on the liability of $ nil and $ 563,705 for the three months ended March 31, 2026 and March 31, 2025 respectively, capitalized into the process plant (note 5) on the condensed interim consolidated balance sheets and gain (loss) on revaluation of the liability of $ nil and $ 4,669,460 for the three months ended March 31, 2026 and March 31, 2025, respectively. The revaluation is because of a change in projections of the key assumptions: The key assumptions used in the revaluation are production of 700,000,000 lbs of zinc, 385,000,000 lbs of lead, 8,700,000 oz of silver over 14 years and long-term commodity prices of 1.20 $/lb to 1.28 $/lb for zinc, 0.91 $/lb to 0.93 $/lb for lead, 27.76 $/oz to $31.96 $/oz for silver, and timing of production. On June 5, 2025, the existing metals purchase agreement (the “Metals Purchase Agreement”) dated June 23, 2023, by and among the Company, Silver Valley, and Sprott Streaming, pursuant to which Sprott Streaming previously advanced a $ 46,000,000 deposit to Silver Valley, was terminated and exchanged (the “Exchange Agreement”) for (i) 200,000,000 shares of the Company’s common stock; (ii) the CD3; and (iii) an additional 1.65 % life-of-mine gross revenue royalty (note 6) on primary and secondary claims comprising the Bunker Hill Mine. Silver Loan On August 8, 2024, the Company entered into definitive agreements with Monetary Metals Bond III LLC, an entity established by Monetary Metals & Co., for a silver loan in an amount of U.S. dollars equal to up to 1.2 million ounces of silver, to be advanced in one or more tranches, in support of the re-start and ongoing development of the Bunker Hill Mine (the “Silver Loan”). In June 2025, the Company and Monetary Metals & Co. agreed to amend the rate of interest of the silver loan reducing it from 15 % to 13.5 % effective August 9, 2025. In consideration for Monetary Metals’ participation in the June 5, 2025 restructuring transactions of Bunker Hill and Silver Valley, Bunker Hill agreed to pay the following fees to Monetary Metals: a fee in the amount of $ 249,000 due and payable on August 8, 2025 and $ 249,000 due and payable on August 8, 2026. The Company determined that the amendments to the terms of the Silver Loan should not be treated as an extinguishment of the Silver Loan and have therefore been accounted for as a modification. On January 30, 2026, the Company closed the final tranche of the Silver Loan in the principal amount of $ 4,763,110 , being the number of U.S. dollars equal to 50,958 ounces of silver . After deduction of financing costs and the three months ending February 8, 2026 interest payment on the principle amount of ounces outstanding and prepaying some of the May 8, 2026 interest payment the Company received $ nil . The Company determined that in accordance with ASC 815 Derivatives and Hedging, the Silver Loan is valued and recorded as a single instrument, with the periodic changes to fair value accounted through earnings, profit and loss. The fair value of the Silver Loan was determined using the Black-Derman-Toy (“BDT”) model. BDT models the evolution of interest rates over time using a binomial tree structure by capturing level of interest rates and volatility and estimates the value of the prepayment option by assessing how the borrower’s incentive to prepay changes with interest rate movements. The key inputs include: Schedule of Estimates Value of Prepayment Option by Assessing Interest Rate Movements Reference Valuation Date Maturity Date Contractual Interest Rate Interest Rate Volatility Risk-free rate Credit Spread Risk- adjusted rate Tranche 1-6 Dec 31, 2025 Aug 8, 2027 13.5 % 24.4 % 3.47 % 7.78 % 19.04 % Tranche 1-7 Mar 31, 2026 Aug 8, 2027 13.5 % 30.0 % 3.72 % 8.87 % 20.38 % 15 The resulting fair values of the Silver Loan at March 31, 2026, and December 31, 2025, were as follows: Reference March 31, 2026 December 31, 2025 Silver Loan $ 84,846,065 $ 80,950,239 The loss on changes in fair value of Silver Loan recognized on the condensed interim consolidated statements of income (loss) and comprehensive income (loss) during the three months ended March 31, 2026, and March 31, 2025, were $ 4,905,892 and $ 6,068,932 respectively. The portion of changes in fair value that is attributable to changes in the Company’s credit risk is accounted for within other comprehensive income during the three months ended March 31, 2026, were $ ( 1,010,066 ) , and $ 1,491,644 related to 3 month ended March 31, 2025 . The Company performs quarterly testing of the covenant of the Silver Loan and was in compliance with all such covenants as of March 31, 2026. $15,000,000 Debt Facility On June 23, 2023, the Company closed a $ 21,000,000 debt facility with Sprott which was available for draw at the Company’s election for a period of 2 years. Any amounts drawn will bear interest of 10 % per annum, from the later of the Funding Date and June 30, 2027, to the date of repayment in full, at the rate of per cent 15.0 % per annum, which is payable annually in cash or capitalized at the Company’s election. The maturity date of any drawings under the Debt Facility will be June 30, 2030 . For every $ 5,000,000 or part thereof advanced under the Debt Facility, the Company will grant a new 0.5% life-of-mine gross revenue royalty, on the same terms as the Royalty, to a maximum of 2.0% on the Primary Claims and 1.4% on the Secondary Claims. The Company may buy back 50% of these royalties for $ 20,000,000 . On January 31, 2025, the Company drew $ 6,000,000 on the debt facility. On January 17, 2025, the Company drew $ 5,000,000 on the debt facility. The proceeds were bifurcated between host debt and the underlying sale of mineral interest to Sprott (note 6). On December 12, 2024, the Company drew $ 5,000,000 on the debt facility. The proceeds were bifurcated between host debt and the underlying sale of mineral interest to Sprott (note 6). On December 19, 2024, the Company drew $ 5,000,000 on the debt facility. The proceeds were bifurcated between host debt and the underlying sale of mineral interest to Sprott (note 6).

The Company determined that the amendments to the terms of the debt facility should not be treated as an extinguishment of the debt facility and have therefore been accounted for as a modification. The Company recorded accretion expense on the debt facility of $ 207,600 and $ 281,005 for the three months ended March 31, 2026 and March 31, 2025 respectively, and accretion on the liability of $ 378,505 and $ 244,535 for the three months ended March 31, 2026 and March 31, 2025, respectively capitalized into the process plant bringing the net liability to $ 15,745,647 as of March 31, 2026.

Commitments and Contingencies EPA and IDEQ Obligations As stipulated in the agreement with the EPA and as described in Note 8, the Company is required to make two types of payments to the EPA and IDEQ, one for historical water treatment cost-recovery to the EPA, and the other for ongoing water treatment. Water treatment costs incurred through December 2021 are payable to the EPA, and water treatment costs incurred thereafter are payable to the IDEQ. The IDEQ (as done formerly by the EPA) invoices the Company on an annual basis for the actual water treatment costs, which may exceed the recognized estimated costs significantly. When the Company receives the water treatment invoices, it records any liability for actual costs over and above any estimates made and adjusts future estimates as required based on these actual invoices received. The Company is required to pay for the actual costs regardless of the periodic required estimated accruals and payments made each year. During 2025, the Company commenced discussions with the EPA and the IDEQ to advance a second amendment to the Amended Settlement Agreement. Specifically, the Company is seeking a restructure of the ongoing obligations to the EPA and IDEQ. Discussions continued through the first quarter of 2026 and remain ongoing. Crescent Legal Proceeding On July 28, 2021, a lawsuit was filed in the U.S. District Court for the District of Idaho brought by Crescent Mining, LLC (“Crescent” or “Plaintiff”). The named defendants include Placer Mining, Robert Hopper Jr., and the Company. The lawsuit alleges that Placer Mining and Robert Hopper Jr. intentionally flooded the Crescent Mine during the period from 1991 and 1994, and that the Company is jointly and severally liable with the other defendants for unspecified past and future costs associated with the presence of acid mine drainage in the Crescent Mine. The Plaintiff requested unspecified damages. On September 20, 2021, the Company filed a motion to dismiss Crescent’s claims against it, contending that such claims are facially deficient.  On March 2, 2022, the court granted in part and denied in part the Company’s motion to dismiss. The court granted the Company’s motion to dismiss in respect of Crescent’s cost recovery claim under CERCLA Section 107(a), and declaratory judgment, tortious interference, trespass, nuisance and negligence claims. These claims were dismissed without prejudice. The court denied the motion to dismiss filed by Placer Mining Corp. for Crescent’s trespass, nuisance and negligence claims. Crescent later filed an amended complaint on April 1, 2022. Placer Mining Corp. and Bunker Hill Mining Corp are named as co-defendants. Bunker Hill responded to the amended filing, refuting and denying all allegations made in the complaint except those that are assertions of fact as a matter of public record. The Company believes Crescent’s lawsuit is without merit and is defending the claims on behalf of itself and Placer Mining Corp. pursuant to an indemnification granted by Company of Placer Mining Corp. granted pursuant to the sale and purchase agreement executed between the companies for the Mine on December 15, 2021. During 2025, the Company attended a mediation session with the plaintiff. The lawsuit continues to advance through the discovery and pre-trail phase, in which information is gathered and exchanged. 13. Deferred Tax liability A valuation allowance is provided for deferred tax assets for which it is more likely than not that the related tax benefits will not be realized. The Company analyzes its deferred tax assets and, if it is determined that the Company will not realize all or a portion of its deferred tax assets, it will record or increase a valuation allowance. Conversely, if it is determined that the Company will likely ultimately be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced. 14.
