Resolution Minerals (ASX: RML) advances Horse Heaven drill campaign with one-third of 2026 program complete

1 July 2026 – Adelaide, Australia | Resolution Minerals Ltd (ASX:RML; OTCQB:RLMLF) has completed one-third of its planned 2026 drilling campaign at the Horse Heaven Antimony-Tungsten-Gold-Silver Project in Idaho, USA, with sixteen diamond drill holes completed at the Golden Gate South prospect as the Company advances exploration of gold and tungsten mineralisation.

A total of 4,470 metres has now been drilled across the sixteen completed diamond core holes, with the program progressing on schedule using two drill rigs. The campaign forms part of a planned 13,700-metre, 45-hole exploration program designed to define the scale and extent of gold mineralisation at Golden Gate North and Golden Gate South, while also targeting tungsten mineralisation associated with the historic Golden Gate Tungsten Mine and surrounding soil anomalies. 

All completed drill core has been logged and photographed, with geological teams recording lithology, alteration and mineralisation before sampling. The first two batches of samples, covering holes HH-GG26-001 to HH-GG26-004, have been dispatched for multi-element laboratory analysis, marking the next stage of the exploration program. 

Golden Gate is located within Resolution's Horse Heaven Project in Idaho and sits immediately adjacent to Perpetua Resources' recently permitted Stibnite Gold Project, one of the largest antimony-gold developments in the United States. The drilling update follows continued momentum at Horse Heaven, including the recent selection of the Antimony Ridge prospect for FAST-41 Transparency Coverage under the US Permitting Council.

Craig Lindsay, Resolution's CEO of US Operations, stated:

"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."

With approximately one-third of the drilling campaign now complete, Resolution expects to continue advancing the program over coming months, with assay results from the first completed holes to be released as they become available. The 2026 campaign is expected to provide further insight into the potential scale of gold and tungsten mineralisation across the Golden Gate system and support the Company's broader exploration strategy at Horse Heaven.
