BIGHORN METALS CORP. ANNOUNCES TWO-FOR-ONE FORWARD STOCK SPLIT AND ENGAGEMENT OF DS MARKET SOLUTIONS INC. FOR MARKET-MAKING SERVICES

Bighorn Metals Corp.'s board of directors has approved a subdivision of the company's issued and outstanding common shares on a two-for-one basis, subject to any shareholder approval required under the company's articles or applicable law. Each shareholder will receive one additional common share for each common share held. The company believes that the stock split may enhance the liquidity and marketability of its common shares, and make them more accessible to a broader range of investors. However, there can be no assurance that the stock split will achieve these objectives.

The record date for the stock split will be Sept. 23, 2026. The common shares are expected to commence trading on the Canadian Securities Exchange on a split-adjusted basis at the opening of trading on the record date. Shareholders of record as of the close of trading on the record date will be entitled to receive the additional common shares. The stock split remains subject to acceptance by the CSE.

The company currently has 22,713,635 common shares issued and outstanding. Following completion of the stock split, the company will have 45,427,270 common shares issued and outstanding.

The number of common shares issuable upon exercise of the company's outstanding warrants and stock options, and the applicable exercise prices, will be proportionately adjusted to reflect the stock split in accordance with their respective terms and applicable CSE requirements.

The stock split will be completed using the pushout method. Shareholders are not required to surrender their existing share certificates or take any other action. The company's transfer agent, Endeavor Trust Corp., will distribute DRS advices representing the additional common shares to registered shareholders. Beneficial shareholders who hold their common shares through an intermediary will have their accounts updated by their intermediary. The company expects its Cusip number and ISIN to remain unchanged, subject to confirmation from the applicable clearing agencies.

The company also announces that it has engaged the services of DS Market Solutions Inc. to provide equity trading advisory and liquidity provider services in accordance with the policies of the Canadian Securities Exchange. DS Market will trade common shares of the company on the CSE and other trading venues with the objective of maintaining a reasonable market and improving the liquidity of the company's common shares.

Under the terms of the engagement, DS Market will receive compensation of $6,000 per month, payable monthly in advance. The engagement is effective Sept. 4, 2026, on a month-to-month basis, and may be terminated by either party upon 30 days of notice. There are no performance factors contained in the engagement and DS Market will not receive shares or options as compensation. DS Market and the company are unrelated and unaffiliated entities, and at the time of the engagement, neither DS Market nor its principals have any interest, directly or indirectly, in the securities of the company.
