NEWS RELEASE

September 25, 2025 – Vancouver, BC, Canada – Kirkstone Metals Corp. (formerly, Dunbar Metals Corp.) (the “Company”) (TSXV: KSM) is pleased to announce that Tim Henneberry has joined the board of directors of the Company effective immediately. Mr. Henneberry fills the vacancy created by Elizabeth Mitchell, who has stepped down from the board to focus on other ventures. The board of directors of the Company thanks Ms. Mitchell for her service to the Company.

Mr. Henneberry is a Professional Geoscientist registered in British Columbia with 45 years experience in domestic and international exploration and production for precious and base metals, uranium and industrial minerals. After focusing his early career in precious metal production, he shifted to junior mining consulting and shortly thereafter to the management side of junior mining.

Adoption of Equity Incentive Plan and Grant

The Company also announces that its board of directors has approved the adoption of a new omnibus equity incentive plan (the Incentive Plan) to replace the Company’s existing stock option plan. The Incentive Plan continues to limit the number of outstanding incentive securities to 10% of the issued and outstanding common shares of the Company at any given time but now provides for the grant of other types of incentive securities such as restricted share units (“RSUs”), deferred share units and stock options. In accordance with the policies of the TSX Venture Exchange, the new Incentive Plan must be ratified by shareholders. The Company intends to seek shareholder ratification at the next annual general meeting of shareholders.

In connection with the adoption of the new Incentive Plan, the Company has granted 500,000 restricted share units (“RSUs”) to certain directors and officers. The RSUs vest and convert to common shares of the Company after twelve months, subject to the continued eligibility of the holder and ratification of the grant and the Incentive Plan by shareholders.
