Resolution Minerals (ASX: RML) has completed its 2026 diamond drilling campaign at the Horse Heaven antimony-tungsten-gold-silver project in Idaho, finishing 42 holes for 12,236 metres at the Golden Gate prospect.
The program targeted extensions to known gold and tungsten mineralisation across Golden Gate North and Golden Gate South, with an average hole depth of about 290m.
Assay results remain pending for 39 holes and are expected to be released progressively over coming months, with all core logging completed and the final samples due to be dispatched for multi-element analysis within a week.
The campaign follows earlier results that extended gold mineralisation at least 2,000m south of Golden Gate North and supported Resolution’s interpretation of a broader mineralised system at Golden Gate South.
Largest Campaign Completed
The 12,236m campaign was designed to define the scale and extent of gold and tungsten mineralisation across the Golden Gate area.
“The 2026 drill program marks the largest exploration program ever conducted at Horse Heaven,” chief executive officer of US operations Craig Lindsay said.
“I thank the team and the drillers for this accomplishment, [which] marks a major step forward in the development of the project.”
Drilling also tested a substantial tungsten-in-soil anomaly at Golden Gate South and areas around historical scheelite mine workings at Golden Gate North, where scheelite has previously been identified in drill core.
Resolution logged all core for geology, alteration, and mineralisation, with geologists also using shortwave ultraviolet light to identify scheelite, a tungsten-bearing mineral.
Earlier Gold Results
Results from the first three holes reported from this year’s program identified broad gold mineralisation, including 305.7m at 0.64 grams per tonne gold from surface in one hole.
That interval included 17.25m at 1.19g/t gold from 264.85m, while drilling from 2025 had previously returned 189.2m at 1.30g/t gold and 253m at 1.5g/t gold from separate holes.
Resolution says the first three 2026 holes extended gold mineralisation at least 2,000m south from Golden Gate North to Golden Gate South, where soil sampling, geophysics and geological mapping have also contributed to its interpretation.
The remaining assays will provide further evidence on the continuity, scale, and grade of both the gold and tungsten systems targeted by the completed campaign.
US Positioning Gains Visibility
Golden Gate sits within Resolution’s wider Horse Heaven project, which also includes Antimony Ridge and is immediately adjacent to Perpetua Resources’ Stibnite gold project.
Golden Gate and Antimony Ridge have been selected by the US Permitting Council for FAST-41 Transparency Coverage, which is intended to accelerate permitting timelines across the relevant prospects.
Resolution also began trading on Nasdaq on 9 September through an American depositary receipt structure, which the company expects to improve its visibility among US investors, institutions and government organisations.
With drilling now complete, near-term attention shifts to the outstanding assay flow as Resolution assesses the extent of gold and tungsten mineralisation defined by its largest Horse Heaven exploration campaign to date.
