KELLOGG, Idaho and VANCOUVER, British Columbia, March 05, 2026 (GLOBE NEWSWIRE) -- Bunker Hill Mining Corp. (“Bunker Hill” or the “Company”) (TSX-V: BNKR | OTCQB: BHLL), is pleased to announce that it has closed its previously announced “best efforts” private placement offering of units (the “LIFE Units”) of the Company. The Company issued 150,808,332 LIFE Units (approximately 4,308,809 LIFE Units on a post-consolidated basis¹) at a price of C$0.18 per LIFE Unit (C$6.30 on a post-consolidated basis¹) for gross proceeds of C$27,145,500 (the “Brokered Offering”), which included the full exercise of the agents’ overallotment option.

The Company also issued 8,926,668 additional LIFE Units (approximately 255,048 LIFE Units on a post-consolidated basis¹) at a price of C$0.18 per LIFE Unit (C$6.30 on a post-consolidated basis¹) for gross proceeds of C$1,606,800 under a concurrent private placement, on a non-brokered basis (the “Non-Brokered Offering”, and together with the Brokered Offering, the “Offering”).

Concurrently with the Offering, a cornerstone investor exercised existing common share purchase warrants at C$0.17 per warrant (C$5.95 on a post-consolidated basis¹) for additional proceeds to the Company of C$5,000,000 (the “Warrant Exercise”), resulting in aggregate gross proceeds of C$33,752,300 to the Company from the Brokered Offering, the Non-Brokered Offering, and the Warrant Exercise.

Each LIFE Unit consists of one share of common stock of the Company (a “Common Share”) and one common share purchase warrant of the Company (a “Warrant”). Each Warrant entitles the holder thereof to purchase one additional Common Share at an exercise price of C$0.30 per share (C$10.50 on a post-consolidated basis^1,2) for a period of 36 months from issuance.

The Offering was completed by a lead agent and sole bookrunner, on its own behalf and on behalf of a syndicate of agents (the “Agents”). A finder assisted in respect of the Brokered Offering (the “Finder”).

The Company intends to use the net proceeds of the Offering to provide working capital for the ramp-up of the Bunker Hill Mine to commercial production, for exploration and for general corporate purposes.

The Offering was completed on a prospectus-exempt basis pursuant to the ‘listed issuer financing exemption’ under Part 5A of National Instrument 45-106 – Prospectus Exemptions, as modified by Coordinated Blanket Order 45-935 Exemptions from Certain Conditions of the Listed Issuer Financing Exemption of the Canadian Securities Administrators (together, the "LIFE Exemption").

In connection with the closing of the Brokered Offering, the Company paid to the Agents aggregate cash fees in the amount of C$1,579,290 and issued to the Agents an aggregate of 8,782,833 non-transferrable compensation options (“Compensation Options”), representing: (i) 6.0% of the gross proceeds of the Brokered Offering, other than the gross proceeds raised from certain sales pursuant to a president’s list (the “President’s List Sales”); and (ii) 3.0% of the gross proceeds raised from President’s List Sales (in each case, less any amount of cash fees and Compensation Options issued to the Finder). Each Compensation Option is exercisable to acquire one Common Share at a price of C$0.18 (C$6.30 on a post-consolidated basis^1,3) per share for a period of 24 months from issuance.

The Company paid to the Finder a cash fee of C$47,820, representing: 3.0% of the gross proceeds of the Brokered Offering from subscribers introduced by the Finder to the Company (the “Introduced Subscribers”); and issued to certain principals of the Finder an aggregate of 256,667 Compensation Options representing 3.0% of the LIFE Units sold under the Brokered Offering to the Introduced Subscribers. The purchase of LIFE Units by certain insiders of the Company constituted a “related party transaction” within the meaning of TSX Venture Exchange (“TSXV”) Policy 5.9 and Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101”). The Company has relied on the exemptions from the valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a) of MI 61-101 in respect of such insider participation. Insider participation accounted for an aggregate of 300,000 LIFE Units (approximately 8,571 on a post-consolidated basis) sold under the Offering.

This press release does not constitute an offer to sell or a solicitation of an offer to buy any of the securities in the United States. The securities have not been registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), or any state securities laws and may not be offered or sold within the United States or to or for the account or benefit of a U.S. person (as defined in Regulation S under the U.S. Securities Act) unless registered under the U.S. Securities Act and applicable state securities laws or an exemption from such registration is available.

The LIFE Units issued are not subject to a statutory hold period under applicable Canadian securities laws, in accordance with the Listed Issuer Financing Exemption. The LIFE Units are subject to a minimum six-month hold period in accordance with applicable U.S. securities laws. The Company has agreed to file within five business days, a registration statement to register the resale of the LIFE Units and to use commercially reasonable efforts to have the registration statement declared effective by the U.S. Securities and Exchange Commission (the “SEC”) within 60 days after the initial filing date of the registration statement.

Forward-looking statements are not comprised of historical facts. Forward-looking statements include estimates and statements that describe the Company’s future plans, objectives or goals, including words to the effect that the Company or management expects a stated condition or result to occur. Forward-looking statements may be identified by such terms as “believes”, “anticipates”, “expects”, “estimates”, “may”, “could”, “would”, “will”, “plan” or variations of such words and phrases.

Forward-looking statements in this news release include, but are not limited to, statements regarding the intended use of the net proceeds of the LIFE Offering; and the Company’s ability to secure sufficient project financing to complete the construction of the Bunker Hill Mine and move it to commercial production in a manner that maximizes shareholder value.

Forward-looking statements reflect material expectations and assumptions, including, without limitation, expectations and assumptions relating to: Bunker Hill’s ability to receive sufficient project financing for the construction of the Bunker Hill Mine on an acceptable timeline, on acceptable terms, or at all; our ability to service our existing debt and meet the payment obligations thereunder; further drilling and geotechnical work supporting the planned restart and operations at the Bunker Hill Mine; the future price of metals; and the stability of the financial and capital markets. Factors that could cause actual results to differ materially from such forward-looking statements include, but are not limited to, those risks and uncertainties identified in public filings made by Bunker Hill with the SEC and with applicable Canadian securities regulatory authorities, and the following: Bunker Hill’s ability to use the net proceeds of the LIFE Offering in a manner that will increase the value of stockholders’ investments; the dilution of current stockholders as a result of the consummation of the LIFE Offering; the Company’s ability to obtain all necessary regulatory and stock exchange approvals with respect to the LIFE Offering and the Reverse Stock Split, including the approval of the TSXV and the Stockholder Consent; Bunker Hill’s ability to operate as a going concern and its history of losses; Bunker Hill’s inability to raise additional capital for project activities, including through equity financings, concentrate offtake financings or otherwise; the fluctuating price of commodities; capital market conditions; restrictions on labor and its effects on international travel and supply chains; failure to identify mineral resources; further geotechnical work not supporting the continued development of the Bunker Hill Mine or the results described herein; failure to convert estimated mineral resources to reserves; the preliminary nature of metallurgical test results; the Company’s ability to raise sufficient project financing, on acceptable terms or at all, to restart and develop the Bunker Hill Mine and the risks of not basing a production decision on a feasibility study of mineral reserves demonstrating economic and technical viability, resulting in increased uncertainty due to multiple technical and economic risks of failure which are associated with this production decision including, among others, areas that are analyzed in more detail in a feasibility study, such as applying economic analysis to resources and reserves, more detailed metallurgy and a number of specialized studies in areas such as mining and recovery methods, market analysis, and environmental and community impacts and, as a result, there may be an increased uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including increased risks associated with developing a commercially mineable deposit, with no guarantee that production will begin as anticipated or at all or that anticipated production costs will be achieved; the Company requiring additional capital expenditures than anticipated, resulting in delays in the expected restart timeline; failure to commence production would have a material adverse impact on the Company’s ability to generate revenue and cash flow to fund operations; failure to achieve the anticipated production costs would have a material adverse impact on the Company’s cash flow and future profitability; delays in obtaining or failures to obtain required governmental, environmental or other project approvals; political risks; changes in equity markets; uncertainties relating to the availability and costs of financing needed in the future; the inability of the Company to budget and manage its liquidity in light of the failure to obtain additional financing, including the ability of the Company to complete the payments pursuant to the terms of the agreement to acquire the Bunker Hill Mine complex; inflation; changes in exchange rates; fluctuations in commodity prices; delays in the development of projects; and capital, operating and reclamation costs varying significantly from estimates and the other risks involved in the mineral exploration and development industry.
