Drilling Paused on the Nighthawk Gold/Silver Project, Nevada

Bitterroot Resources Ltd. (symbol BTT, TSX-Venture Exchange) has paused drilling at the Company’s 100%-owned Nighthawk Gold/Silver Project in the Walker Lane Belt of west-central Nevada. The drilling contractor has advised that it is unable to continue due to recurring mechanical issues. All drilling equipment is being demobilized from the site. Another Nevada-based contractor is expected to restart the drill program in late January 2026.

Drilling will test for structurally-controlled, near-surface oxidized epithermal gold/silver mineralization and intrusion-hosted base and precious metals mineralization. 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. The Nighthawk claims are located on Federally-managed (BLM) land in Esmeralda County, approximately 50 kilometres west of Tonopah, NV.

Additional information on the Nighthawk Gold/Silver Project is available on the Company’s website www.bitterrootresources.com.
