10 November 2025 – Adelaide, Australia: Resolution Minerals Ltd (ASX: RML) is pleased to announce that Reverse Circulation (RC) drilling is now underway at the Golden Gate Prospect, located within the Horse Heaven Project in Idaho, USA. The program aims to rapidly follow up on the significant new gold discovery recently confirmed through diamond drilling.
Key Highlights
-
RC rig mobilised to Golden Gate: A three-hole, 2,789 ft (850 m) RC drill program has commenced to extend the footprint of the new gold discovery.
-
Testing strike, width, and depth extensions: Drilling will step out from maiden discovery holes HH-GG25-001C, HH-GG25-002C, and HH-GG25-003C, all of which ended in mineralisation.
-
Large intrusion-related gold system: Results from the core program confirmed Golden Gate as a large, open gold system situated only 6 km from the fully permitted Stibnite Gold-Antimony Mine.
-
Efficient program design: The RC drilling is being undertaken within the existing permit area, offering a fast, cost-effective means to expand the mineralised footprint ahead of a larger 50-hole program currently in permitting.
-
Ongoing newsflow: Results will be released progressively as assays become available, complementing remaining Phase 1 diamond core results.
Advancing a Significant Gold System
The new RC program is strategically designed to test northern and southern strike extensions, western width extensions, and depth continuity of the mineralised system.
-
Hole DS18-4 targets the northern strike and western width extension of HH-GG25-001C, HH-GG25-002C, and HH-GG25-003C (planned depth: 984 ft / 300 m).
-
Hole DS16-3 targets depth, width, and southern strike extensions of HH-GG25-001C and HH-GG25-002C (planned depth: 820 ft / 250 m).
-
Hole DS19-2 targets the southern strike extension of HH-GG25-003C (planned depth: 984 ft / 300 m).
All work is being conducted within the bounds of the existing exploration permit.
RML’s CEO of US Operations, Craig Lindsay, said:
“The first three diamond core holes at Golden Gate all intersected broad, continuous gold mineralisation from surface and each of them ended in mineralisation. That is a standout results for a maiden program and confirms Gold Gate as a new gold discovery in a highly prospective and strategically important U.S critical minerals district. By bringing an RC rig onsite now, we are able to rapidly and cost-effectively step out from the discovery zone to begin defining the scale of the system. The aim of this program is simple, to extend the mineralised footprint and set up the platform for our much larger 50-hole follow-up drill program. With drilling now underway, remaining core assays to come, and project wide exploration continuing, we are positioned for strong and sustained newsflow as we advance Golden Gate.”
Project Context
The Golden Gate Prospect lies within the Horse Heaven Project, which hosts two major antimony-gold-silver-tungsten targets, Golden Gate and Antimony Ridge. The project is strategically located near the Stibnite Gold Project, an advanced-stage development considered one of the largest known antimony-gold resources in the United States.
