Resolution Minerals Ltd (ASX:RML, OTC:RLMLF) has strengthened its antimony-gold portfolio during the June 2025 quarter, following the acquisition of the Horse Heaven Gold Antimony, Silver and Tungsten Project in Idaho, United States.
The brownfield Horse Heaven Project builds on the company’s recent acquisition of the Drake East and Neardie antimony projects in New South Wales. Horse Heaven hosts two historically mined, structurally controlled prospects — the Golden Gate Fault Zone (GGFZ) and Antimony Ridge Fault Zone (ARFZ) — both open in all directions and associated with non-JORC compliant mineral resources.
Previous drilling has confirmed significant mineralisation.

Exploration insights from NSW projects
During the quarter, Resolution reported final results from a LiDAR survey at the Drake East Gold Antimony Project, which identified more than 700 features interpreted as historical workings. These are believed to relate to vein-style gold and antimony mineralisation.
In addition, the company completed a review of its Spur South Gold Copper Project in NSW. The project is considered prospective for porphyry-skarn style gold-copper systems, with the major Cadia-Ridgeway deposit, owned by Newmont, located just 25 kilometres to the east.
Diversified critical minerals portfolio
Resolution now holds a diversified portfolio focused on gold and antimony, complemented by silver, tungsten, copper and uranium interests. The Horse Heaven and Drake East Projects position the company among the ASX’s leading antimony-focused explorers.
Project reviews continued during the quarter, including assessment of the George Project’s potential for ultra-high purity quartz (UHPQ) and its significant uranium-bearing palaeo-channel deposits.
The company also maintained its tenements in good standing and remains open to acquisition and divestment opportunities across its portfolio.
