Highlights

  • Resolution Minerals acquires Horse Heaven Project in the US.
  • NSW projects reveal significant gold-antimony exploration features.
  • Portfolio strengthened with diversified critical minerals focus.

Resolution Minerals Ltd (ASX:RML) has expanded its critical minerals portfolio with the addition of the Horse Heaven Gold Antimony, Silver and Tungsten Project in Idaho, United States. This move enhances the company’s position in the exploration sector, aligning with broader trends among ASX100 companies seeking to secure resources across strategic minerals.

The Horse Heaven Project is a brownfield site featuring historically mined zones — the Golden Gate Fault Zone and Antimony Ridge Fault Zone. Both areas remain open for further exploration and are associated with known mineralisation trends, providing opportunities for future geological work.

Exploration Progress Across New South Wales

LiDAR Surveys Reveal Rich Historical Workings

In New South Wales, Resolution Minerals has advanced exploration on the Drake East Gold Antimony Project. A LiDAR survey revealed hundreds of features interpreted as historical workings, likely linked to vein-style gold and antimony mineralisation. These insights offer a clearer picture of the site’s geological potential and historical resource activity.

Review of Spur South Gold Copper Project

Alongside gold and antimony, Resolution is reviewing its Spur South Gold Copper Project, considered prospective for porphyry-skarn style gold-copper systems. The project’s location, near a major gold-copper deposit, further supports its exploration interest within a region already known for significant mineral resources.

Diversified Project Portfolio

Resolution’s current portfolio spans gold, antimony, silver, tungsten, copper, and uranium interests. With both Horse Heaven in the US and Drake East in NSW, the company holds a distinctive position as an antimony-focused explorer on the ASX. Additional project assessments include evaluating the George Project for ultra-high purity quartz and uranium-bearing palaeo-channel deposits.

The company’s strategy continues to focus on advancing its key projects while keeping tenements in good standing. Ongoing project reviews and openness to new acquisitions aim to sustain its momentum in the critical minerals space.
