Resolution Minerals conducted a 2026 diamond drilling campaign at the 100% owned Horse Heaven antimony-tungsten-gold-silver project in Idaho. The program involved drilling 42 holes totaling 12,236 metres at the Golden Gate prospect to define the scale of gold and tungsten mineralisation.

Following the completion of the drilling, the company reported significant gold assay results. Recent drilling at the Golden Gate South prospect extended the gold mineralised zone to an approximate width of 600 metres. High-grade intercepts were recorded, including 1.0m at 14.8 g/t gold and 12 g/t silver in hole HH-GG26-004C, as well as 1.0m at 7.0 g/t gold in hole HH-GG26-005C. Company leadership indicated these results may represent feeder zones and suggest mineralisation could extend continuously between the Golden Gate South and Golden Gate North areas.

As the company advances the project, it is targeting a maiden resource estimate for Golden Gate in the first quarter of 2027. Results for 36 additional drill holes remain pending. Beyond exploration, Resolution Minerals is pursuing a ‘mine-to-metals’ strategy, which includes developing domestic U.S. processing solutions for critical minerals like tungsten and antimony to support national mineral security.
