Resolution Minerals hits one-third of Idaho drill campaign

Resolution Minerals has completed about a third of its 2026 drilling program at the Horse Heaven project in Idaho as the U.S. pushes to secure domestic supplies of antimony and tungsten. The work is testing gold and critical mineral targets near a major gold project in central Idaho, with early samples now at the lab.

Why it matters: - The Horse Heaven project targets antimony and tungsten, two minerals the United States considers critical for defense, semiconductor, industrial and clean energy uses. - U.S. policymakers and manufacturers are looking for domestic alternatives as global trade restrictions tighten, including Chinese export controls. - Horse Heaven sits in a strategically watched mining district in central Idaho, next to Perpetua Resources' permitted Stibnite Gold Project.

What happened: - Resolution Minerals Ltd completed 16 diamond drill holes at the Golden Gate South prospect in Idaho. - The drilling totaled 4,470 metres, or 14,665 feet. - The completed work represents about one-third of the company’s planned 13,700-metre, 45-hole 2026 drilling program. - Two drill rigs remain active as the campaign continues. - The company’s current campaign is advancing at the Horse Heaven Antimony-Tungsten-Gold-Silver Project in central Idaho.

The details: - The drill program is designed to define the scale and continuity of gold mineralisation at Golden Gate North and Golden Gate South. - The program is also testing tungsten mineralisation around the historic Golden Gate Tungsten Mine. - Resolution Minerals is testing a broader tungsten soil anomaly in the area. - All completed drill core has been logged and photographed. - Geological teams have recorded lithology, alteration and mineralisation before sampling. - The first two batches of samples, covering drill holes HH-GG26-001 through HH-GG26-004, have been sent for multi-element laboratory analysis. - Assay results are expected as they become available. - Craig Lindsay, Resolution’s CEO of U.S. Operations, said the drill rate at Golden Gate South has been strong and that core logging and sampling are current.

Between the lines: - The project is being framed as part of a broader U.S. push to reduce reliance on overseas critical mineral supply chains. - Resolution Minerals is using the drilling program to test whether Horse Heaven could host more than one mineral system, which could raise the district’s strategic value. - The company’s selection for FAST-41 Transparency Coverage at its nearby Antimony Ridge prospect adds a federal-process tailwind for the broader land package. - The market is paying close attention to projects that can potentially supply defense-linked minerals inside the U.S.

What's next: - Resolution Minerals will continue drilling at Golden Gate South and the surrounding targets. - More assay results should come in as the first sample batches are processed. - The company will use the results to evaluate the scale of gold and tungsten mineralisation across Horse Heaven. - The broader exploration program is expected to continue assessing whether the district hosts significant gold and critical mineral systems.

The bottom line: - Resolution Minerals is making steady progress on a drill campaign aimed at minerals the U.S. wants closer to home, and the next assay results will help show whether Horse Heaven has district-scale potential.
