Highlights
- Resolution Minerals has completed 763m of drilling across the first three holes of its 2026 Golden Gate drill campaign.
- The drill holes intersected sulphide mineralisation including pyrite and arsenopyrite within altered, faulted, sheared and veined granites.
- A second MP1500 diamond core drill rig has been mobilised to site to accelerate drilling activities at Golden Gate.
- The campaign is targeting both gold and tungsten mineralisation at Golden Gate South and Golden Gate North.
Resolution Minerals Ltd (ASX:RML) (OTCQB:RLMLF) has reported encouraging early results from its 2026 drilling campaign at the Golden Gate target within the Horse Heaven Antimony-Tungsten-Gold-Silver Project in Idaho, USA. The first three holes completed under the program have encountered key indicators of potential gold and tungsten mineralisation, supporting the company’s broader exploration objectives across the project area.
Early Drilling Encounters Extensive Mineralisation Indicators
The company has completed 763m of drilling to date in three drill holes - HH-GG26-001C, HH-GG26-002C and HH-GG26-003C, which intersected extensive sulphide mineralisation, including pyrite and arsenopyrite, within highly altered faulted, sheared and veined granites. These geological features are considered comparable to those identified in previously mineralised holes at Golden Gate North and Golden Gate South.
The three holes were drilled approximately 500m south of the 2025 drilling area at Golden Gate South.
Drill Program Expanding with Additional Rig
The 2026 campaign is planned to include up to 13,700m (45,000 feet) of diamond core drilling across 45 holes.
To accelerate exploration, the company has mobilised a second MP1500 diamond core drill rig, which is expected to begin operations next week.
Focus on Gold and Tungsten Potential
The current campaign is focused on evaluating both gold and tungsten mineralisation at Golden Gate. The drilling program has commenced south of the Golden Gate South target and will later extend to areas north of Golden Gate North. The company is evaluating the broader scale potential across both target zones, where mineralisation remains open in multiple directions.
Current drilling is also aimed at testing known tungsten mineralisation at Golden Gate South, including a 500m by 600m coincident gold and tungsten soil anomaly. Future drilling phases are expected to assess extensions of this anomaly as well as continuations of historically mined mineralised zones. Tungsten mining previously took place at Golden Gate, with the last recorded production occurring in 1980.
