Resolution Minerals Ltd (ASX:RML, OTCQB:RLMLF) has completed 16 diamond core holes at the Golden Gate South prospect within its Horse Heaven Antimony-Tungsten-Gold-Silver Project in Idaho, marking strong progress in a major 2026 drill campaign targeting gold and tungsten extensions.
The company said 4,470 metres had been drilled across the completed holes, representing about one-third of the planned 13,700-metre program, with two drill rigs operating on site.
Resolution’s Horse Heaven Antimony-Tungsten-Gold-Silver Project – Relationship of Antimony Ridge (Sb) with Golden Gate (Au) and Golden Gate Tungsten (W).
Sixteen holes completed
Resolution has drilled the holes to planned total depths at Golden Gate South, with the completed holes including HH-GG26-001 to HH-GG26-007 and HH-GG26-010 to HH-GG26-018.
The average hole depth is around 279 metres, with the program designed to test the scale and extent of gold mineralisation along strike and at depth across Golden Gate North and Golden Gate South.
The drilling is also targeting tungsten mineralisation around the historical Golden Gate Tungsten mine and a broader tungsten soil anomaly at Golden Gate South.
Core logged and samples dispatched
All core from the completed holes has been logged, with company geologists and contractors recording geology, alteration and mineralisation. The core has also been inspected for scheelite, a tungsten ore mineral, with detailed photographs and interval records taken where scheelite was identified.
Resolution has dispatched two large batches of core samples for multi-element analysis, including all samples from holes HH-GG26-001 to HH-GG26-004.
Craig Lindsay, Resolution’s CEO of US operations, said the company was pleased with the pace of drilling at Golden Gate South.
“I am exceedingly pleased with the drill rate we are achieving at Golden Gate South. All core needs to be carefully logged, including but not limited to lithology, alteration and mineralisation, then appropriately sampled. On this front, we are up to date. We have also submitted two large batches of samples,for which we are certainly looking forward to receiving the results.”
Strategic Idaho location
Golden Gate forms part of Resolution’s broader Horse Heaven project in Idaho, immediately adjacent to Perpetua Resources’ recently permitted Stibnite Gold Project, a large antimony-gold development.
The Horse Heaven project comprises 729 US federal lode mining claims covering 14,580 acres, including 719 mining claims and 10 lode mining claims referred to as the Oberbillig Group. The company said the mining claims were understood to be in good standing.
The project area hosts gold, antimony, tungsten and silver mineralisation associated with hydrothermally altered and fractured granodiorites.
Drilling builds on earlier gold hits
The current campaign follows previous Golden Gate drilling that delivered broad gold intercepts, including 197.5 metres at 1.26 g/t gold, 265.2 metres at 0.60 g/t gold and 253.0 metres at 1.50 g/t gold.
The 2026 Golden Gate program is designed to define the scale and extent of tungsten and gold mineralisation, starting at Golden Gate South.
The Golden Gate drill program remains ongoing, with up to 45 holes and 13,700 metres of diamond core drilling planned. Resolution said drill hole results would be released on an ongoing basis as the campaign progresses.
