BUNKER HILL ANNOUNCES ELECTION TO ISSUE SHARES IN SATISFACTION OF INTEREST PAYMENT OBLIGATIONS

Bunker Hill Mining Corp. has elected to issue an aggregate of 15,378,473 shares of common stock of the company in full satisfaction of the interest payable as of June 30, 2025, under certain debt instruments, including: (i) an aggregate of 1,291,667 interest shares to certain holders of 5.0 per cent Series 1 secured convertible debentures for the aggregate interest of $103,333.33 (U.S.) owing thereunder; (ii) an aggregate of 4,260,417 interest shares to certain holders of 5.0 per cent Series 2 secured convertible debentures for the aggregate interest of $340,833.33 (U.S.) owing thereunder; and (iii) an aggregate of 9,826,389 interest shares to the lenders under a 10-per-cent loan facility for the aggregate interest of $786,111.11 (U.S.) 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. The loan facility matures on June 30, 2030.

In accordance with the terms of the debt instruments, the company will issue the interest shares at a price of eight U.S. cents (approximately 11 cents) per interest share based on 90 per cent of the 10-day volume-weighted average trading price of the shares of common stock of the company on the TSX Venture Exchange on the trading days beginning on June 13, 2025, and ending on June 26, 2025.

In connection with the interest payments, the company will issue an aggregate of 15,163,195 interest shares to certain managed accounts of Sprott Private Resource Streaming and Royalty Corp. 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. 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 per cent 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 June 26, 2025.

The issuance of the interest shares is subject to the terms and conditions of the debt instruments as well as the receipt of all regulatory approvals, including, without limitation, the approval of the TSX-V. Once issued, the interest shares will be subject to a four-month-and-one-day hold period in accordance with applicable Canadian securities laws.
