Bunker Hill Announces Marketed Public Offering

TORONTO, Nov. 22, 2022 - Bunker Hill Mining Corp. (the "Company") (CSE: BNKR) is pleased to announce that it has filed a preliminary short form prospectus (the "Prospectus") with the securities commissions in each of the provinces of Canada, other than Quebec (the "Canadian Jurisdictions"), in connection with a commercially reasonable "best efforts" marketed public offering of common stock of the Company (the "Offered Shares") for minimum aggregate gross proceeds of C$7,000,000 (the "Minimum Offering") and maximum aggregate gross proceeds of C$12,000,000 (the "Maximum Offering").

Concurrently with the filing of the Prospectus with the securities commissions in the Canadian Jurisdictions, the Company has filed a registration statement (the "Registration Statement") with the United States Securities and Exchange Commission (the "SEC") with respect to the sale of the Offered Shares in the United States. Sales of the Offered Shares in the United States will be on the same terms as sales of the Offered Shares in Canada, and aggregate sales of the Offered Shares in Canada and the United States will together constitute the Offering. The Registration Statement is not yet effective, and the Offered Shares may not be sold, nor may offers to buy be accepted, prior to the time the registration statement becomes effective.

The Offering will be priced in the context of the market, with the final terms of the Offering to be determined at the time of pricing. There can be no assurance as to whether or when the Offering may be completed, or as to the actual size or terms of the Offering. The Offering will be conducted by Echelon Capital Markets ("Echelon") and Roth Capital Partners, LLC ("Roth", and together with Echelon, the "Lead Agents") as co-lead agents and co-bookrunners, along with Laurentian Bank Securities Inc. ("Laurentian" and, together with the Lead Agents, the "Agents") as co-manager.

The Company intends to grant the Agents an option exercisable, in whole or in part, at any time not later than the 30th day following the closing of the Offering, to purchase up to an additional 15% of the shares of common stock of the Company (the "Common Shares") offered in the proposed Offering for market stabilization purposes and to cover over-allotments, if any.

The proposed Offering will be completed (i) by way of a final short form prospectus to be filed in the Canadian Jurisdictions; (ii) by way of a final prospectus to be filed in the United States; and (iii) outside Canada and the United States on a basis which does not require the qualification or registration of any of the Company's securities under domestic or foreign securities laws. Pending closing of the Offering, all subscription funds will be deposited and held by the Agents in trust. If the Minimum Offering is not met or the closing date does not occur within a prescribed period from the date a receipt is issued for the final short form prospectus or such other time as may be agreed between purchasers and the Agents, the Offering will be discontinued and all subscription monies will be returned to purchasers.

Closing of the Offering is subject to customary closing conditions, including but not limited to, the Minimum Offering being met and the receipt of all necessary approvals, including (i) the approval of the securities commissions in the Canadian Jurisdictions, (ii) the SEC shall have declared the Registration Statement effective, and (iii) the approval of the Canadian Securities Exchange (the "CSE") to list the Offered Shares (as well as the Common Shares issuable pursuant to the exercise of compensation warrants to be issued to the Agents upon the successful closing of the Offering) and the securities regulatory authorities.

The Company intends to use the net proceeds of the Offering, if any, for the completion of a number of key milestones for the restart and development of the Bunker Hill mine located in Shoshone County, Idaho, United States (the "Bunker Hill Mine"), as well as for working capital and general corporate purposes. Such milestones include: (i) completion of the ramp decline connecting the 5 and 6 levels of the mine; (ii) completion of demolition of the existing maintenance shop; (iii) completion of plant engineering and civil works for installation of the process plant; and (iv) finalization of the purchase of the new ball mill, which is the key anticipated remaining component of the process plant required to restart the mine.

Forward-looking statements may be identified by such terms as "believes", "anticipates", "expects", "estimates", "may", "could", "would", "will", or "plan". Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties. Although these statements are based on information currently available to the Company, the Company provides no assurance that actual results will meet management's expectations. Risks, uncertainties and other factors involved with forward-looking information could cause actual events, results, performance, prospects and opportunities to differ materially from those expressed or implied by such forward-looking information.
