Resolution Minerals (ASX: RML) has encountered additional gold and significant tungsten mineralisation in drilling at the Golden Gate Fault Zone within its Horse Heaven antimony-gold project in the US.
The company reported broad intervals of near-surface mineralisation in the final five holes of last year’s shallow reverse circulation program at Golden Gate North.
Best results include 8 metres at 0.14% tungsten from 79.3m within 21m at 0.06% tungsten from 70.1m, 99m at 0.23 grams per tonne gold from surface including 20m at 0.35g/t from 0m and 9.1m at 0.65g/t from 89.9m, and 133.7m at 0.55g/t gold from 376.5m including 15.6m at 1.1g/t from 166.7m.
They complement assays from diamond core drilling at the same target that included 197.5m at 1.26g/t gold from 34m, 265.2m at 0.6g/t gold from surface, and 253m at 1.5g/t gold from surface.
Continuous or Parallel Deposits
Resolution has planned more drilling to determine if the Golden Gate North and Golden Gate South targets form a continuous single discovery or represent two parallel deposits.
The “combined” deposit is reported to be open in all directions, along strike to the northeast and southwest (which is the orientation of the controlling shear zone), across strike to the northwest and southeast and at depth.
The gold envelope is already believed to be of considerable size, with identified mineralisation covering a strike length of 1,500m and a width of 300m.
The company’s drilling focus for 2026 at Golden Gate is to further define the size
and shape of the Golden Gate North and Golden Gate South gold deposits with a combination of diamond core and reverse circulation holes.
‘A Major Gold Discovery’
Executive director Aharon Zaetz called the results from the Golden Gate campaigns “exceptional”.
“Every hole drilled by us at Golden Gate has intercepted significant intervals of gold mineralisation—it is easy to conclude that the 2025 campaign has resulted in a major gold discovery, currently open ended in all directions,” he said.
“It is a gold discovery totally in keeping with the intrusive-related, shear-hosted exploration model we have for the original Golden Gate Fault Zone and it is a credit to our technical team for recognising such potential.”
Resolution will also use the 2026 drilling campaign to define a maiden resource estimate for Golden Gate.
