Resolution Minerals Commences Drilling at U.S.-Based Horse Heaven Critical Metals Project

Resolution Minerals Ltd has officially commenced drilling at its Horse Heaven Gold-Antimony-Tungsten Project in Idaho, U.S.A., strategically located adjacent to Perpetua Resources’ Stibnite Gold Mine – a project with a market capitalization of approximately A$3 billion.

The Phase 1 drilling program, now underway, targets high-grade gold, antimony, and tungsten mineralization at the Golden Gate prospect and across other emerging zones, including past-producing antimony and tungsten mines. The program will include up to 3,000 meters of diamond core drilling in the initial phase and has the potential to expand to 6,000 meters across 20 holes.

Key Highlights

  • Drill Program Underway: Phase 1 drilling commenced following contractor appointment, U.S. Forest Service approval, and bonding completion. Initial drilling will comprise ~3,000 meters with potential to double scope.
  • High-Value Strategic Metals: The program aims to confirm historical gold intersections and assay for previously unsampled critical minerals — antimony and tungsten.
  • Exceptional Past Drill Results: Notable intercepts include:
    • 85.34 m @ 0.937g/t Au (incl. 38.10 m @ 1.459 g/t Au)
    • 105.16 m @ 0.787 g/t Au (incl. 51.82 m @ 0.990 g/t Au)
    • 30.48 m @ 1.354 g/t Au
  • Strategic Importance to the U.S. : With no domestic antimony production, the U.S. is 100% import-reliant. Horse Heaven could become a key source of military-grade antimony.
  • Environmental Baseline Studies Commencing: These will underpin the next phase of permitting and support expanded drilling operations.
  • U.S. Government Engagement: RML has engaged leading strategic advisors Thorn Run Partners and Clewett Global Services to advance government relations and access federal incentives.
  • OTCQB Listing Expected Imminently.

Resolution CEO of U.S. Operations Craig Lindsay commented:

"Drilling is now underway. This is an important milestone for Resolution and we are pleased with progress. This would not be possible without the welcome support of the local town of Yellow Pine and the US Forest Service as we move forward with developing the next source of critical metals to meet the United States’ growing domestic demand."

Next Steps

  • Complete Phase 1 drilling by October 2025.
  • Launch environmental studies to support expanded operations.
  • Advance stakeholder engagement with U.S. Government and regulatory bodies.
