Scale is the story at Golden Gate North. Resolution Minerals reported on October 26 that assays from the first three holes of its 2026 season at the Horse Heaven antimony-tungsten-gold-silver project in Idaho confirm a gold zone at least 500 metres long, 200 metres wide and 300 metres deep — in ground that sits immediately beside Perpetua Resources' recently permitted Stibnite gold project.
- HH-GG26-032C: 324 metres at 0.49 g/t Au from surface, including 92.4 metres at 0.54 g/t Au from 215.7 m, 25.5 metres at 0.82 g/t Au from 190.2 m and 8.7 metres at 1.05 g/t Au from 62.5 m.
- HH-GG26-031C: 322 metres at 0.37 g/t Au from surface, including 30.8 metres at 0.88 g/t Au from 76.2 m.
- HH-GG26-039C: 134.2 metres at 0.40 g/t Au from surface, including 51.7 metres at 0.53 g/t Au from 82.5 m — drilled almost 500 metres north of the other two holes.
- The zone is open: mineralization remains open northeast and southwest, and gold-in-soil results suggest potential for a further ~500 metres north and a similar distance south.
- Most of the program is still unreported: the completed 2026 program drilled 42 diamond holes for 12,236 metres across Golden Gate North and South; assays are incomplete for more than 32 holes, and initial tungsten assays are also awaited.
Why the geometry matters more than the grade
None of these intercepts is high-grade — the long runs sit between 0.37 and 0.49 g/t gold. What they establish is continuity: two fan holes mineralized from surface nearly to the bottom of the hole, and a third hole half a kilometre north carrying the same broad, low-grade signature. That is the shape of a bulk-tonnage system rather than a narrow vein, and it extends the 2025 discovery drilling — which included 253.0 metres at 1.50 g/t Au in HH-GG25-003C — down-dip to at least 300 metres. The open question the company is now pointing at is the roughly 2,000-metre corridor between Golden Gate North and Golden Gate South, about 2 km apart, which its planned 2027 program — currently being permitted — is designed to test, alongside infill and the northern extension.
Horse Heaven is a four-metal project: alongside the gold, Resolution is working the Antimony Ridge system and historical tungsten stockpiles, and says a processing plan for those stockpiles and metallurgical testing are advancing in parallel.
The honesty box
Every interval in this release is a downhole length, not a true width — the company states the intervals do not necessarily represent true widths, so the zone's real thickness is not yet established. There is no mineral resource estimate at Golden Gate: "500 metres long, 200 wide, 300 deep" describes drilled mineralization, not a compliant resource, and no economic study exists. The grades in the new holes are lower than the best 2025 intercepts the release cites alongside them — continuity is improving while headline grade is moderating, and both facts belong in the picture. The further-500-metres extensions rest on gold-in-soil anomalies, which are surface indicators, not drilling. And with more than 32 of 42 holes still unassayed, this is the first three holes of a large program, not its verdict.
What to watch
The remaining 32-plus assay releases from Golden Gate North and South, the first tungsten assays from the 2026 program, permitting progress on the 2027 corridor program, and any move toward a maiden resource estimate.
