On June 11, 2026, the stockholders of Bunker Hill Mining Corp. (the “Company”) approved amendments to the Company’s Restricted Stock Unit Plan (the “Amended RSU Plan”) and Stock Option Plan (the “Amended Option Plan”) at the Company’s annual meeting of stockholders.

Amended Restricted Stock Unit Plan

The Amended RSU Plan increases the maximum number of shares of common stock issuable thereunder from 2,648,555 shares to 3,501,396 shares, representing 7.5% of the Company’s issued and outstanding common shares as of April 28, 2026.

The Amended RSU Plan also revises the insider participation limits to provide that the maximum number of shares issued under the Amended RSU Plan and any other security-based compensation arrangement of the Company during any 12-month period to insiders of the Company, as a group, may not exceed 10% of the Company’s issued and outstanding common shares, calculated as of the applicable grant date.

In addition, the Amended RSU Plan removes certain restrictions previously applicable to consultants, permits participation by persons providing investor relations services to the Company, revises the stockholder approval requirements applicable to certain plan amendments, and clarifies the Board’s authority to make amendments necessary to comply with applicable regulatory requirements, including the requirements of the Toronto Stock Exchange (“TSX”).

The Amended RSU Plan further includes administrative, housekeeping and compliance-related amendments to reflect the Company’s graduation from the TSX Venture Exchange (“TSX-V”) to the TSX, including revisions to participant eligibility provisions, replacement of certain TSX-V-specific provisions and terminology, and related conforming changes.

Amended Stock Option Plan

The Amended Option Plan revises the minimum exercise price of options granted thereunder to provide that the exercise price of an option may not be less than the closing price of the Company’s common shares on the TSX on the date of grant.

The Amended Option Plan also removes certain vesting restrictions and other requirements previously applicable to options granted to persons providing investor relations services, revises the insider participation limits to conform to TSX requirements, removes certain limitations applicable to consultants and investor relations service providers, and clarifies the Board’s authority to make amendments necessary to comply with applicable regulatory requirements, including the requirements of the TSX.

The Amended Option Plan further includes administrative, housekeeping and compliance-related amendments to reflect the Company’s graduation from the TSX-V to the TSX, including revisions to participant eligibility provisions, replacement of certain TSX-V-specific provisions and terminology, and related conforming changes.

A more detailed description of the Amended RSU Plan and the Amended Option Plan is contained in the Company’s definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission on May 13, 2026 (the “Proxy Statement”) under the headings “Approval of Amendments to the Restricted Stock Unit Incentive Plan” and “Approval of Amendments to the Stock Option Plan,” respectively, which descriptions are incorporated herein by reference.

Certain statements in this news release are forward-looking and involve a number of risks and uncertainties. Such forward-looking statements are within the meaning of that term in Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended, as well as within the meaning of the phrase ‘forward-looking information’ in the Canadian Securities Administrators’ National Instrument 51-102 – Continuous Disclosure Obligations (collectively, “forward-looking statements”). 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 Company’s objectives, goals or future plans, including the restart and development of the Bunker Hill Mine and the anticipated timing thereof. 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 restart and ongoing development of the Bunker Hill Mine on acceptable terms or at all; 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 U.S. Securities and Exchange Commission (the “SEC”) and with applicable Canadian securities regulatory authorities, and the following: the Company’s inability to raise additional capital for project activities, including through equity financings, concentrate offtake financings or otherwise; capital market conditions; restrictions on labor and its effects on international travel and supply chains; failure to identify mineral resources; failure to convert estimated mineral resources to reserves; the preliminary nature of metallurgical test results; the Company’s ability 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; 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. Although the Company believes that the assumptions and factors used in preparing the forward-looking statements in this news release are reasonable, undue reliance should not be placed on such statements or information, which only applies as of the date of this news release, and no assurance can be given that such events will occur in the disclosed time frames or at all, including as to whether or when the Company will achieve its project finance initiatives, or as to the actual size or terms of those financing initiatives. The Company disclaims any intention or obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, other than as required by law. No stock exchange, securities commission or other regulatory authority has approved or disapproved the information contained herein.

Readers are cautioned that the foregoing risks and uncertainties are not exhaustive.
