BUNKER HILL MINING CORP

Item 2.01. Completion of Acquisition or Disposition of Assets. The information set forth in the Introductory Note and under Item 3.02 and Item 5.03 of this Current Report on Form 8-K is incorporated by reference in its entirety into this Item 2.01. At the effective time of the Arrangement (the “ Effective Time ”), among other things: Each Silver47 shareholder received 0.1724 (the “Exchange Ratio”) shares of common stock, par value $0.000001 per share, of Bunker Hill (“Bunker Hill Common Stock” and each share of Bunker Hill Common Stock, a “Bunker Hill Share”) in exchange for each Silver47 Share held immediately prior to the completion of the Arrangement (the “Consideration Shares”); provided that no fractional Bunker Hill Shares were issued in the Arrangement, and where the aggregate number of Bunker Hill Shares to be issued to a person as consideration under or as a result of the Arrangement resulted in a fraction, the number of Bunker Hill Shares received by that securityholder was rounded down to the nearest whole Bunker Hill Share, and no person was entitled to any compensation in respect of a fractional Bunker Hill Share. Each Silver47 option (a “Silver47 Option”) outstanding immediately prior to the Effective Time, whether vested or unvested, was exchanged for an option (each, a “Replacement Option”) to acquire Bunker Hill Shares equal to (rounded down to the nearest whole number) the number of Silver47 Shares subject to such Silver47 Option immediately prior to the Effective Time multiplied by the Exchange Ratio, with the exercise price per Bunker Hill Share subject to a Replacement Option equal to the exercise price per Silver47 Share subject to the corresponding Silver47 Option immediately before the Effective Time divided by the Exchange Ratio (with the aggregate exercise price payable on any particular exercise rounded up to the nearest whole cent). Each Replacement Option is exercisable until the original expiry date of the corresponding Silver47 Option, except that Replacement Options held by or on behalf of an individual who did not continue as a director, officer, employee or consultant of Bunker Hill or any of its affiliates (including Silver47) following 60 days after the Closing Date expire on the earlier of (i) the original expiry date of the Silver47 Option and (ii) the date that is 120 days following the Closing Date. Each Silver47 restricted share unit (a “Silver47 RSU”) outstanding immediately prior to the Effective Time, whether vested or unvested, was deemed to be immediately and unconditionally vested and was settled by Silver47 at the Effective Time, net of applicable withholdings, in exchange for Silver47 Shares, which were transferred to Bunker Hill under the Plan of Arrangement, after which the holders were treated as Silver47 shareholders for purposes of the Arrangement. Each Silver47 warrant (a “Silver47 Warrant”) outstanding immediately prior to the Effective Time, whether vested or unvested, was exchanged for a warrant (each, a “Replacement Warrant” and, together with the Replacement Options, “Replacement Convertible Securities”) to acquire from Bunker Hill a number of Bunker Hill Shares equal to the number of Silver47 Shares subject to the Silver47 Warrant immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded down to the nearest whole Bunker Hill Share, with the exercise price per Bunker Hill Share subject to a Replacement Warrant equal to the exercise price per Silver47 Share subject to the corresponding Silver47 Warrant immediately before the Effective Time divided by the Exchange Ratio (with the aggregate exercise price payable on any particular exercise rounded up to the nearest whole cent). Replacement Warrants otherwise have the same terms, including expiry, as the corresponding Silver47 Warrants, subject to the exercise limitations and cashless exercise rights set forth in the applicable Supplemental Warrant Agreement, as described below. In connection with the Arrangement, Bunker Hill, Silver47, Odyssey Trust Company, as resigning warrant agent, and Computershare Trust Company of Canada, as successor warrant agent (and, in the case of the supplemental indenture relating to the June 17, 2025 warrant indenture, Summa Silver Corp.), entered into Supplemental Warrant Agreements, dated as of November 6, 2026 (the “ Supplemental Warrant Agreements ”), relating to the warrant agreements, dated June 17, 2025, September 16, 2025, and January 14, 2026, governing certain Silver47 Warrants (the “ Existing Warrant Agreements ”). The Supplemental Warrant Agreements provide for the resignation of Odyssey Trust Company as warrant agent, the appointment of Computershare Trust Company of Canada as successor warrant agent and the transfer to Computershare Trust Company of Canada of the rights, powers, duties and obligations of the warrant agent under the Existing Warrant Agreements. The Supplemental Warrant Agreements also add provisions to the Existing Warrant Agreements pursuant to which, if Bunker Hill determines that no registration statement registering the Bunker Hill Shares issuable upon exercise of the applicable Replacement Warrants is effective, or that the use of any such registration statement is suspended, no holder will be permitted to exercise such Replacement Warrants unless an exemption from the registration requirements of the Securities Act of 1933, as amended (the “ Securities Act ”), and applicable state securities laws is available. In that event, until the earlier of (i) such registration statement becoming effective or ceasing to be suspended and (ii) 5:00 p.m. (Vancouver time) on August 1, 2027, September 16, 2028 or January 14, 2029, as applicable, such Replacement Warrants may also be exercised on a cashless basis in accordance with the formula set forth in the applicable Supplemental Warrant Agreement if the current market price of the Bunker Hill Shares exceeds the applicable exercise price. In addition, if Bunker Hill determines that U.S. state securities laws are not preempted with respect to exercises of such Replacement Warrants, Bunker Hill may elect, by written notice to the warrant agent, to permit such exercises on a cashless basis in accordance with such formula. The foregoing description of the Supplemental Warrant Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the Supplemental Warrant Agreements, which are filed as Exhibits 4.1, 4.2 and 4.3 to this Current Report on Form 8-K and are incorporated by reference herein.

Item 3.02. Unregistered Sales of Equity Securities. The information disclosed under Item 2.01 is incorporated into this Item 3.02 in its entirety. On the Closing Date, Bunker Hill issued approximately 36,325,517 Consideration Shares, and the outstanding Silver47 Options and the outstanding Silver47 Warrants were exchanged for approximately 2,907,755 Replacement Options and approximately 10,993,476 Replacement Warrants, respectively. The securities issued pursuant to the Arrangement Agreement on the Closing Date were issued in reliance upon Section 3(a)(10) of the Securities Act. The Consideration Shares represent approximately 43% of the outstanding shares of Bunker Hill Common Stock immediately following the Effective Time. Section 3(a)(10) of the Securities Act exempts from the registration requirements under the Securities Act the issuance of securities which have been approved, after a hearing upon the substantive and procedural fairness of the terms and conditions of the relevant transaction, at which all persons to whom it is proposed the securities will be issued shall have the right to appear, by any court expressly authorized by law to grant such approval. Prior to the special meeting of Silver47 shareholders, Silver47 obtained an interim order from the Supreme Court of British Columbia (the “ Court ”) providing for notice to all persons to whom the Consideration Shares and the Replacement Convertible Securities would be issuable and confirming their right to appear at the hearing for the final order. Following a hearing at which Silver47 securityholders that received Consideration Shares and Replacement Convertible Securities had the right to appear, the Court issued a final order on November 2, 2026 declaring the substantive and procedural fairness of the terms and conditions of the Plan of Arrangement to such Silver47 securityholders.

Item 3.03. Material Modification to Rights of Security Holders. The information set forth in Item 5.03 of this Current Report on Form 8-K is incorporated by reference in its entirety into this Item 3.03.
