Resolution Minerals Ltd (ASX:RML) has announced significant gold discoveries at its Golden Gate Prospect, located within the Horse Heaven Gold-Antimony-Tungsten-Silver Project in Idaho, USA. The company’s maiden drill program has yielded broad intervals of near-surface gold mineralisation, confirming the existence of a large, open intrusion-related gold system.
Recent drilling results highlighted the success of three diamond holes, all ending in gold mineralisation. Notably, hole HH-GG25-003C reported a remarkable down hole interval of 253.0 meters at 1.50 grams per tonne (g/t) gold from surface, with additional intervals of 111.9 meters at 2.31 g/t gold and 18.3 meters at 3.98 g/t gold. The highest assay result recorded so far in this hole was an impressive 5.91 g/t gold over a width of 1.5 meters.
Another significant hole, HH-GG25-002C, reported a down hole interval of 265.2 meters at 0.60 g/t gold, including 89.9 meters at 1.15 g/t gold. These findings come shortly after a previous report on October 28, 2025, which detailed another successful drill hole, HH-GG25-001C, achieving 189.2 meters at 1.30 g/t gold from a depth of 34 meters.
Expanding Exploration Efforts
The results from these drilling activities position Golden Gate as a promising site for continued exploration. All three drill holes have returned broad gold mineralisation from surface, demonstrating a level of continuity that is rare at this stage of a drilling program. Craig Lindsay, CEO of US Operations for Resolution Minerals, expressed enthusiasm over these results, stating, “These results confirm that Golden Gate hosts a large, robust gold system with all holes returning broad gold mineralisation from surface and finishing in mineralisation.”
The project is strategically located within a region rich in critical minerals and aligns with U.S. government priorities. The geology, sulphides, and alteration observed at Golden Gate bear similarities to the nearby Stibnite gold-antimony deposit, located approximately 16 kilometers away.
Resolution Minerals is taking immediate action to capitalise on these findings. A Reverse Circulation drill rig is being mobilised to Golden Gate to follow up on the initial results, and assay batch results from seven additional core holes are expected to be released progressively in the coming months.
Future Directions for Horse Heaven Project
The Horse Heaven project is shaping up as a large-scale, multi-commodity initiative, with potential for not just gold, but also antimony, silver, and tungsten. The company is pursuing a dual-track strategy that focuses on both gold exploration and resource definition, while also advancing pathways for other critical minerals.
In addition to the drilling at Golden Gate, Resolution Minerals is nearing completion of a project-wide stream sediment program designed to refine drill targeting across the broader Horse Heaven tenure. Once assay results from this program are analysed, the company will integrate them into the next phase of regional exploration.
At Antimony Ridge, the company is applying for a drill permit to explore deeper extensions of known shallow antimony mineralisation. A portable drill rig has been trialled in this area, with results pending. The company is also collecting representative samples of stibnite-silica vein mineralisation for initial metallurgical test work and mineralisation characterisation studies.
In summary, the recent discoveries at Golden Gate underscore the potential of the Horse Heaven project, and with ongoing exploration activities, Resolution Minerals is positioning itself to uncover further valuable resources in this promising district.
