Resolution Minerals (ASX:RML) has completed 42 diamond core drill holes totalling 12,236m at its Horse Heaven Antimony-Tungsten-Gold-Silver Project in Idaho, US.
The company finished drilling at the Golden Gate North and Golden Gate South prospects, with assay results pending for 39 holes. Resolution confirms core logging is complete across all drill metres, with samples to be dispatched for multi-element analysis within the coming week.
The 2026 program represents the largest exploration campaign ever conducted at Horse Heaven, targeting extensions of gold and tungsten mineralisation around historical mine workings and a broad tungsten anomaly in soil samples.
Chief Executive of US Operations Craig Lindsay says he is ‘exceedingly pleased’ by the completion of drilling.
“I thank the team and the drillers for this accomplishment. This work marks a major step forward in the development of the project,” Lindsay says.
The drilling follows results from the first three holes released this year, which extended gold mineralisation at least 2,000m south from Golden Gate North to Golden Gate South.
The best intercept to date shows 305.7m @ 0.64 grams per tonne gold (Au) from surface, including 17.25m @ 1.19g/t Au from 264.85m.
Previous drilling in 2025 delivered multiple broad gold intercepts, including 253m @ 1.50g/t Au; and 189.2m @ 1.30g/t Au from 34.1m, including 70.8m @ 2.24g/t Au from 128.8m.
The program also targeted tungsten mineralisation, with scheelite identified visually using shortwave ultraviolet light in early drill holes. Scheelite occurs with quartz and manganese in veins within heavily oxidised quartz-feldspar altered granite.
Horse Heaven sits immediately adjacent to Perpetua Resources‘ (TSX:PPTA) recently permitted Stibnite Gold Project. Both Golden Gate and Antimony Ridge have been selected for FAST-41 transparency coverage from the US Permitting Council, accelerating permitting timelines.
The company expects to release assay results over coming months as they are received from the laboratory.
Resolution holds 729 US federal lode mining claims covering 5,900 hectares at Horse Heaven, comprising 719 mining claims and 10 lode mining claims in the Oberbillig Group.
Resolution Minerals is a mineral explorer focused on discovering and developing precious and critical battery metals, including antimony, gold, tungsten, and copper.
