Bitterroot contractor starts drilling at Nighthawk

Executive Summary

• Bitterroot Resources Ltd. has initiated a 10-hole, 3,000- to 4,000-metre reverse circulation (RC) drilling program at its 100%-owned Nighthawk gold/silver project in Nevada.
• The drilling targets untested Miocene-age structures and potential intrusions covered by alluvium and colluvium, aiming to identify structurally controlled, near-surface oxidized epithermal gold/silver mineralization and intrusion-hosted base/precious metals.
• The program is expected to continue until late December 2025, with results anticipated in the latter part of Q1 2026.

Key Details

• Drilling Program Scope: 10-hole reverse circulation (RC) program totaling 3,000 to 4,000 metres.
• Location: Nighthawk gold/silver project, Walker Lane belt of west-central Nevada, on federally managed (BLM) land in Esmeralda County, approximately 50 kilometres west of Tonopah.
• Target Geology: Untested Miocene-age structures and potential intrusions; structurally controlled, near-surface oxidized epithermal gold/silver mineralization; intrusion-hosted base and precious metals mineralization.
• Exploration History: Targets developed via regional exploration, outcrop examination, detailed aeromagnetic survey, prospecting, and soil geochemical surveys.
• Historical Data: Nighthawk hosts gold/silver-mineralized boulders with grades ranging from 0.83 to 38 grams gold/tonne, associated with anomalous soil geochemistry.
• Project Context: Located several kilometres immediately west of and contiguous with third-party claims covering the past-producing Boss mine and the undeveloped Castle, Berg, and Black Rock gold deposits.
• Timeline: Drilling expected to continue until late December 2025; results expected as early as the latter part of Q1 2026.
• Qualified Person: Charles Greig, MSc, PGeo.
