BUNKER HILL ANNOUNCES COMPLETION OF REVERSE STOCK SPLIT

Bunker Hill Mining Corp. has completed the previously announced one-for-35 reverse stock split of its common stock (par value of 0.0001 U.S. cent) and preferred stock (par value of 0.0001 U.S. cent). The shares of common stock will begin trading on a postconsolidation basis on the TSX Venture Exchange at market open today, March 6, 2026.

Reverse stock split

As of close of business on March 5, 2026, there were 1,596,641,338 common shares issued and outstanding. Immediately following the reverse stock split, a total of approximately 45,618,323 common shares are expected to be issued and outstanding, subject to adjustments for rounding. There are no shares of preferred stock outstanding. The exercise or conversion price and the number of common shares issuable under any of the company's outstanding convertible securities and equity incentive plans, as applicable, have been proportionately adjusted in connection with the reverse stock split in accordance with their terms.

The new Cusip number for the common shares is 120613823, and the new ISIN (international securities identification number) is US1206138232. Registered stockholders of Bunker Hill who hold their common shares in certificated form will receive a letter of transmittal with instructions for surrendering certificates representing their preconsolidated common shares. Such stockholders will need to return to Computershare Investor Services Inc., as registrar and transfer agent, a completed letter of transmittal, together with such surrendered certificates, in order to receive a certificate or direct registration system (DRS) advice statement for their postconsolidated common shares. Registered stockholders whose preconsolidated common shares are represented by a DRS advice statement are not required to return a completed letter of transmittal to Computershare and instead will be automatically issued a new DRS advice statement for the number of postconsolidated common shares held. Holders of convertible securities are also not required to return any letter of transmittal in respect of their convertible securities.

The reverse stock split remains subject to the final approval of the TSX-V.

LIFE (listed issuer financing exemption) offering closing clarification

Further to the company's press release dated March 5, 2026, the company wishes to clarify that each unit offered pursuant to the company's offering conducted pursuant to the listed issuer financing exemption, as further described therein, consists of one common share and one-half of one common share purchase warrant of the company. Each whole warrant entitles the holder thereof to purchase one additional common share at an exercise price of 30 cents per share ($10.50 on a postconsolidation basis) for a period of 36 months from issuance.
