• Offtake Amendments: The Company, through its wholly-owned subsidiary Silver Valley Metals Corp, has entered into the previously announced amending agreements with respect to existing zinc and lead offtake agreements between Teck and Silver Valley. As a result of these amendments, among other amendments, the offtakes will now apply to life-of-mine production rather than the original 5-year term.

The Company satisfied the shareholder approval requirements of the TSX-V applicable to the issuance of the Common Shares to the Participating Directors, as Non-Arm’s Length Parties, by way of the Stockholder Consent.

• Amendments to the Monetary Metals Silver Loan: The Company and Silver Valley completed the previously announced amendment of the existing secured promissory note purchase agreement dated August 8, 2024 (as previously amended) and secured promissory note with Monetary Metals Bond III LLC, as further described in the Company’s news release dated May 16, 2025.

• Amendments to Existing Security and Intercreditor Arrangements: The Company amended its existing security and intercreditor arrangements with Sprott Streaming, Monetary Metals and MineWater to, among other things, reflect the termination of the Metals Purchase Agreement and other certain other transactions described herein, and to account for Teck under such arrangements. Concurrently with the Equity Financings, the Company entered into an amended and restated intercreditor agreement with the Original Intercreditor Parties and Teck, which among things, deferred certain royalty payments and imposed restrictions on early prepayment of principal amounts under outstanding debt obligations of the Company for so long as amounts are outstanding under the SP Facility, and allowed certain portions of Teck’s security interest under the SP Facility to be granted on a first priority basis, as further described in the Company’s news release dated May 16, 2025.

• Equity Payment: The Company, together with Silver Valley, entered into the previously announced equity payment agreement with C & E Tree Farm, L.L.C., pursuant to which the Company issued 4,761,905 Units to C&E at a deemed price equal to the Offering Price to satisfy US$500,000 of the purchase price payable under an existing option agreement between Silver Valley and C&E, dated March 3, 2023. Each Unit issued pursuant to the Equity Payment Agreement consists of one Common Share and one-half of one Warrant, with each whole Warrant exercisable for one additional Warrant Share at an exercise price of C$0.25 per Warrant Share for a period of three (3) years following the date of issuance, being June 5, 2028.

All securities issued pursuant to the restructuring transactions described above (i) are subject to a four months plus one day hold period in accordance with applicable Canadian securities laws and, if applicable, the policies of the TSX-V and (ii) have not been registered under the U.S. Securities Act or any U.S. state securities laws and may not be offered or sold in the United States without registration under the U.S. Securities Act and all applicable state securities laws or compliance with requirements of an applicable exemption therefrom.

In connection with the transactions described herein (including the Sprott Subscription), Sprott Streaming was issued an aggregate of 259,802,380 Common Shares, 5,000,000 Warrants and convertible debentures of which the principal amount is convertible into up to 38,320,000 Common Shares. As a result, Sprott Streaming now owns or exercises control over approximately 29.6% of the issued and outstanding Common Shares (or, assuming the exercise of all warrants and the conversion of the full principal amount of the convertible debentures now held by Sprott, approximately 39.1% on a partially diluted basis) and is considered a “Control Person” of the Company. The Company obtained the Stockholder Consent for, among other things, the restructuring transactions with Sprott Streaming and the Sprott Subscription, including the creation of Sprott Streaming as a Control Person of the Company, in satisfaction of the applicable shareholder approval requirements of the TSX-V.

The Company has also entered into an investor rights agreement with Sprott Streaming dated June 5, 2025, pursuant to which, among other things, Sprott Streaming has the right to appoint one nominee (or an observer) to the board of directors of Bunker Hill, subject to certain customary exceptions. A copy of the Sprott Investor Rights Agreement will be filed by the Company as a material agreement and will be made available on the Company’s SEDAR+ profile.

Given that Sprott is a “Non-Arm’s Length Party” (as such term is defined in the policies of the TSX-V), the amendment and restatement of the Debt Facility and the granting of the Second Royalty each constituted a “Reviewable Disposition” under TSX-V Policy 5.3 – Acquisitions and Dispositions of Non-Cash Assets and were therefore subject to the TSX-V requirement to provide evidence of value. The Company satisfied this requirement by way of the Stockholder Consent.

Related Party Transactions

Each of the transactions described above with (i) Sprott Streaming, including the issuance of Common Shares in connection therewith, as well as the issuance of Units to Sprott Streaming pursuant to the Sprott Subscription, and (ii) directors and officers of the Company, including the issuance of Common Shares to the Participating Directors in connection therewith, as well as the issuance of Units to directors and officers of the Company under the Brokered Private Placement, constituted a “related party transaction” within the meaning of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions. The Company relied on the exemptions from the formal valuation and minority shareholder approval requirements provided under Sections 5.5(g) and 5.7(e) under MI 61-101 related to the financial hardship of the Company.

Amendment to Articles of Incorporation

The Company also received the approval of a majority of its stockholders, by way of the Stockholder Consent, to proceed with the previously announced amendment and restatement of its articles of incorporation to, among other things, increase the total number of shares of capital stock that the Company is authorized to issue from 1,510,000,000 shares to 2,510,000,000 shares.
