Bunker Hill Announces Filing of Amended Pre-Effective U.S. Registration Statement and Updates on Equity Financing

TORONTO, Feb. 14, 2023 - Bunker Hill Mining Corp. (the "Company") (CSE: BNKR; OTCQB: BHLL) announces that it has filed an amended pre-effective registration statement on Form S-1 (the "Amended Registration Statement") with the United States Securities and Exchange Commission (the "SEC"), in connection with a previously announced proposed commercially reasonable "best efforts" marketed public offering (the "Offering") of common stock in the capital of the Company (the "Offered Shares").

As previously announced, the proposed Offering is envisaged to be conducted in the United States solely by means of a prospectus (the "US Prospectus") to be filed following the effectiveness of a final registration statement on Form S-1 (the "Final Registration Statement"), if such effectiveness occurs. The Offering is also envisaged to be conducted in Canada by means of a short form prospectus (the "Canadian Prospectus") to be filed concurrent with the effectiveness of the Final Registration Statement. Consequentially, the Offered Shares may not be sold in the United States or any of the provinces or territories of Canada (collectively, the "Qualifying Jurisdictions"), nor may offers to buy be accepted in the Qualifying Jurisdictions, prior to the time the Final Registration Statement and the Canadian Prospectus are effective and receipted, respectively, if such effectiveness or receipt occurs.

The Amended Registration Statement includes an assumed offering price of US$0.09 per Offered Share (the "Offering Price"). The actual Offering Price will be determined between the Company and the placement agents and will be included in the US Prospectus in the event that effectiveness of a Final Registration Statement is achieved and the Offering is completed.

The proposed Offering envisages a minimum Offering size of US$6.5 million and a maximum Offering size of US$11.0 million. The Company intends to use the net proceeds of the proposed Offering, if any, for the completion of a number of key milestones for the restart and development of the Bunker Hill Mine, as well as for working capital and general corporate purposes.

The Offering is being conducted by Echelon Capital Markets and Roth Capital Partners, LLC, as co-lead agents and co-bookrunners, along with Laurentian Bank Securities Inc. (collectively, the "Agents") on a commercially reasonable "best efforts" basis. Roth is acting as exclusive placement for the Offering in the U.S., while Echelon and Laurentian are acting as Agents in Canada.

Before investing, readers should review the US Prospectus which will be filed following effectiveness of the Final Registration Statement, if such effectiveness occurs, and other documents the Company has filed with the SEC, for more complete information regarding the Company and the Offering referenced herein. Readers may obtain these documents for free by visiting EDGAR on the SEC website at www.sec.gov.

A copy of the Company's preliminary short form prospectus dated November 21, 2022 is available to view on the Company's SEDAR profile at www.SEDAR.com. The Company has not yet filed the Canadian Prospectus nor received a receipt for the Canadian Prospectus from the applicable securities regulatory authorities in Canada (the "Securities Commissions"), and the Canadian Prospectus remains subject to regulatory approval. There is no guarantee the Company will receive regulatory approval to file the Canadian Prospectus. The Canadian Prospectus will be available to view on the Company's SEDAR profile at www.SEDAR.com if and when the Company receives a receipt for the Canadian Prospectus from the Securities Commissions.
