Highlights
- Drilling at Golden Gate South confirmed a second mineralised shear zone and extended the Golden Gate gold system beyond a 1.5-kilometre strike length.
- Diamond hole HH-GG25-009C intersected 172.2 metres at 0.463 g/t gold, including 27.6 metres at 0.89 g/t gold, and ended in mineralisation.
- Diamond hole HH-GG25-010C returned 225.5 metres of gold mineralisation from surface to end of hole.
- Combined results from Golden Gate North and South indicate broad, near-surface gold mineralisation.
- RML shares rose 10.638% during morning trading on 9 February.
Shares in Resolution Minerals Ltd (ASX:RML) (OTCQB:RLMLF) rose during morning trading on 9 February, with the stock last trading at AUD 0.052, up 10.638%. The increase followed the company’s announcement of a new gold discovery at Golden Gate South within its 100%-owned Horse Heaven Gold-Antimony-Tungsten-Silver Project in Idaho, USA.
Recent drilling intersected broad intervals of near-surface gold mineralisation, extending the Golden Gate system beyond 1.5km strike-length.
Discovery Confirms Second Mineralised Shear Zone
The Golden Gate South discovery confirms the presence of a second mineralised shear zone and expands the known footprint of the Golden Gate gold system.
As part of its maiden 2025 drilling campaign at the Horse Heaven Project, RML completed three diamond core drill holes at the Golden Gate South prospect for a total of 887 metres. Drill holes HH-GG25-008C and HH-GG25-010C were designed to test gold anomalies identified from surface rock sampling. Drill hole HH-GG25-009C was positioned to follow up historical gold intercepts recorded in holes 87-GGR-4, 87-GGR-10 and 87-GGR-45, which are also associated with a low-resistivity CSAMT anomaly.
Diamond drill hole HH-GG25-009C intersected a downhole interval of 172.2 metres grading 0.463 g/t gold, including 27.6 metres at 0.89 g/t gold, with peak values of 3.3 g/t gold over 1.5 metres.
A second diamond hole, HH-GG25-010C, intersected gold mineralisation from surface to end of hole, returning 225.5 metres at 0.14 g/t gold. This result confirms the presence of broad, near-surface mineralisation. Both holes concluded in mineralisation, reinforcing the potential for further extensions below current drilling depths.
Furthermore, HH-GG25-010C hole also intersected near-surface tungsten mineralisation in multiple shallow veins, supporting the project’s multi-commodity potential across gold, antimony and tungsten.
Golden Gate System Extends Over 1.5km
Combined drilling results from Golden Gate North and Golden Gate South now define a mineralised strike length exceeding 1.5 kilometres. Previous drilling at Golden Gate North delivered wide gold intervals, including 189.2 metres at 1.3 g/t gold and 253 metres at 1.5 g/t gold, with mineralisation also remaining open at depth.
Plans Ahead
Looking ahead, the company plans to-
- Conduct an expanded drilling program at Golden Gate from as early as May, targeting further extensions of gold discoveries at Golden Gate North and Golden Gate South.
- Commission a maiden JORC mineral resource estimate at Golden Gate North following completion of the 2026 drilling campaign.
- Test tungsten mineralisation near the historic Golden Gate Tungsten Mine and along the Golden Gate Fault, where soil sampling has identified a tungsten anomaly.
- Advance a new exploration permit to expand the project footprint.
- Undertake initial metallurgical testing, samples from the 2026 Golden Gate drilling program have been submitted.
The Golden Gate South discovery represents a significant step in expanding the Golden Gate gold system at the Horse Heaven Project. With mineralisation identified in all reported drill holes and remaining open along strike and at depth, Resolution Minerals plans further drilling during the 2026 field season. Upcoming work will focus on extending known mineralisation and progressing toward a maiden JORC-compliant mineral resource estimate at Golden Gate North.
