Resolution Minerals Ltd (ASX:RML, OTCQB:RLMLF, FRA:NC3) has completed its major 2026 diamond drilling program at the Horse Heaven Antimony-Tungsten-Gold-Silver Project in Idaho.
The drill program comprised 42 holes drilled for 12,236 metres across the Golden Gate North and South prospects.
The program, the largest exploration campaign undertaken at Horse Heaven, targeted extensions to known gold mineralisation as well as tungsten around historic workings and a broad soil anomaly at Golden Gate South.
Assay results for gold and tungsten from 39 holes remain pending and will be reported progressively over the coming months.
Golden Gate mineralisation extended
Results from the first three holes reported from this year’s program have already extended gold mineralisation at least 2,000 metres south of Golden Gate North, supporting Resolution’s classification of Golden Gate South as a new discovery.
The standout intercept so far is 305.7 metres at 0.64 g/t gold from surface in HH-GG26-003C, including 6.5 metres at 1.33 g/t from 62 metres and 17.25 metres at 1.19 g/t from 264.85 metres.
That builds on broad intersections from Resolution’s 2025 program, including 253 metres at 1.5 g/t gold, 189.2 metres at 1.30 g/t, 265.2 metres at 0.60 g/t and 240.8 metres at 0.64 g/t.
Resolution CEO of US Operations Craig Lindsay stated: “The 2026 drill program marks the largest exploration program ever conducted at Horse Heaven.”
“We await gold and tungsten assay results from the drillhole samples with anticipation… This work marks a major step forward in the development of the project.”

Tungsten remains key target
Alongside gold, the 2026 program tested tungsten mineralisation around the historical Golden Gate Tungsten mine and a significant tungsten-in-soil anomaly at Golden Gate South.
Scheelite, a tungsten-bearing mineral, has been visually identified in drill core using shortwave ultraviolet light, with assays expected to determine the grade and extent of mineralisation.
All drill core has now been logged, with geology, alteration and mineralisation recorded and the remaining samples being prepared for multi-element analysis.
Horse Heaven gains US profile
Horse Heaven sits immediately adjacent to Perpetua Resources’ recently permitted Stibnite Gold Project, while both Golden Gate and Antimony Ridge have been selected for FAST-41 Transparency Coverage by the US Permitting Council, supporting an accelerated permitting pathway.
Resolution also began trading on the Nasdaq on September 9 via an ADR structure, broadening its exposure to US investors as it advances Horse Heaven as a potential domestic source of tungsten and antimony.
