KELLOGG, Idaho and VANCOUVER, British Columbia, Dec. 29, 2025 (GLOBE NEWSWIRE) -- Bunker Hill Mining Corp. (“Bunker Hill” or the “Company”) (TSXV:BNKR | OTCQB:BHLL) announces that it has elected to issue an aggregate of 1,578,430 shares of common stock of the Company (the “Interest Shares”) in full satisfaction of the interest payable as of December 31, 2025 under certain debt instruments (collectively, the “Interest Payments”), including (i) an aggregate of 450,980 Interest Shares to certain holders of 5.0% Series 1 secured convertible debentures (the “Series 1 Debentures”) for the aggregate interest of US$76,666.67 owing thereunder, (ii) an aggregate of 1,127,450 Interest Shares to certain holders of 5.0% Series 2 secured convertible debentures (the “Series 2 Debentures”) for the aggregate interest of US$191,666.67 owing thereunder, together with the Series 1 Debentures and the Series 2 Debentures, the “Debt Instruments”) for the aggregate interest of US$268,333.33 owing thereunder in connection with advances to the Company. The Series 1 Debentures and Series 2 Debentures mature on March 31, 2028 and March 31, 2029, respectively.

In accordance with the terms of the Debt Instruments, the Company will issue the Interest Shares at a price of USD$0.17 (approximately C$0.23) per Interest Share based on 90% of the 10-day volume weighted average trading price of the shares of common stock of the Company on the TSX Venture Exchange (the “TSX-V”) on the trading days beginning on December 12, 2025 and ending on December 29, 2025 (the “Pricing Period”).

In connection with the Interest Payments, the Company will issue an aggregate of 1,503,266 Interest Shares to certain managed accounts of Sprott Private Resource Streaming and Royalty Corp. (“Sprott”) and, accordingly, the issuance of such Interest Shares to Sprott will constitute a “related party transaction” within the meaning of Multilateral Instrument 61-101 – Protection of Minority Shareholder Approval (“MI 61-101”). The Company intends on relying on exemptions from the formal valuation and minority shareholder approval requirements under MI 61-101 as neither the fair market value of the Interest Shares to be issued to Sprott, nor the consideration received for such Interest Shares, will exceed 25% of the Company’s market capitalization. The Company did not file a material change report more than 21 days prior to the election to issue the Interest Shares as the Pricing Period only ended yesterday on December 26, 2025.

In addition to the Interest Shares, the Company has elected to issue shares of common stock of the Company (the “Shares for Services”) in exchange for general consulting services provided under a consulting agreement between the Company and Henderson House Holdings, LLC (the “Consultant”) dated August 1, 2025 (the “Consulting Agreement”). The Consultant was engaged to support the Company with government relations and financing initiatives from Washington, DC. In accordance with the terms of the Consulting Agreement, the Company will issue the Shares for Services, equal to US$15,000.00 per month, and awarded quarterly, over a 12-month period (the “Shares for Services Payment”). The Consulting Agreement also provides for a six percent (6%) cash bonus on any funds raised or awarded as a result of actions, referrals or relationships secured by the Consultant for the Company, as well as bonus awards of 0.5% paid in cash or one percent (1%) paid in shares of common stock of the Company for the following Company milestones:

• Company raise/funding exceeds $60,000.00;
• Company raise/funding exceeds $100,000,000;
• Company raise/funding exceeds $175,000,000; and
• Company raise/funding exceeds $250,000,000.

The Company has elected to issue an aggregate 328,831 Shares for Services to satisfy the Shares for Services Payment for the period beginning on August 1, 2025 and ending on November 30, 2025. The Company will issue the Shares for Services at a price of C$0.1913 per Share for Services based on the 20-day volume weighted average trading price of the shares of common stock of the Company on the TSX-V on the trading days beginning on November 3, 2025 and ending on November 28, 2025.

The issuance of the Interest Shares is subject to the terms and conditions of the Debt Instruments and the issuance of the Shares for Services is subject to the terms and conditions of the Consulting Agreement. Both the Interest Shares and the Shares for Services are subject to the receipt of all regulatory approvals, including, without limitation, the approval of the TSX-V. Once issued, the Interest Shares and the Shares for Services will each be subject to a four-month and one-day hold period in accordance with applicable Canadian securities laws. The Interest Shares and the Shares for Services have not been, and will not be, registered under the United States Securities Act of 1933, as amended (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 in compliance with the requirements of an applicable exemption therefrom.
