DRILLING RESUMES ON THE NIGHTHAWK GOLD/SILVER PROJECT, NEVADA

Drilling has resumed on Bitterroot Resources Ltd.'s 100-per-cent-owned Nighthawk gold/silver project. Nighthawk is located on BLM-managed (U.S. Bureau of Land Management) federal land, approximately 25 miles west of the historic Tonopah gold/silver district in the Walker Lane belt of west-central Nevada.

Drilling is expected to test up to five targets for structurally controlled epithermal gold/silver mineralization. While drilling was paused, several of the previously identified targets were further refined using ambient/active seismic geophysical surveys and proprietary processing software. The seismic surveys were designed to improve target resolution.

The Nighthawk project is contiguous with A2 Gold's Castle project, comprising the past-producing open-pit/heap-leach Boss mine and the undeveloped, near-surface Castle, Berg and Black Rock gold deposits.

Additional information on the Nighthawk gold/silver project is available on the company's website.

About Bitterroot Resources Ltd.

Through its U.S. subsidiary, Trans Superior Resources Inc., Bitterroot owns a 100-per-cent, royalty-free interest in the 219-claim Nighthawk gold/silver project near Tonopah, Nev. Trans Superior also owns a 51-per-cent interest in the LM nickel/copper project in the highly prospective Roland area of the Baraga basin in Michigan's Upper Peninsula. The Baraga basin hosts the United States' only operating nickel/copper mine, Talon Metals Corp.'s (previously Lundin Mining's) Eagle mine, plus the Boulderdash and Roland prospects, which are being aggressively explored by Talon. Bitterroot's LM prospect and Talon's Roland prospect are likely parts of the same nickel/copper-mineralized conduit system. More drilling is planned at LM, subject to financing. Bitterroot also owns 5.9 per cent of Perseverance Metals Inc., a nickel/copper exploration company focused in Quebec and Michigan. Perseverance's management plans to drill new magmatic nickel/copper targets in the Upper Peninsula in early 2026.
