Drilling at Golden Gate, Focused on Gold and Tungsten Mineralisation, is Advancing Rapidly with Encouraging Mineralisation in All Holes Drilled to Date.
- May 21, 2026 (Source) — HIGHLIGHTS
Key indicators of potential gold and tungsten mineralisation have been identified in the first three holes (HH-GG26-001C, HH-GG26-002C, and HH-GG26-003C) of the Company’s 2026 Drill Program (“Drill Program”). - Pervasive metal sulphides have been logged within highly altered sheared, faulted and veined granites that share characteristics very similar to previous well-mineralised holes at Golden Gate North and Golden Gate South.
- The Drill Program is progressing swiftly with three drill holes completed, cumulatively drilled to 763m (or 2,505 ft) total depth.
- To fast track the program further, a second drill rig has arrived on site and is expected to be turning early next week.
- The Drill Program is designed to get some measure of the scalability and extent of gold mineralisation and tungsten mineralisation at Golden Gate North and Golden Gate South.
Resolution Minerals Ltd (ASX: RML; OTCQB: RLMLF) (“Resolution” or the “Company”) is pleased to report outstanding drilling progress with its 2026 Drill Program, with a total of 763m (2,505 ft) of drilling completed to date in three holes (HH-GG26-001C, HH-GG26-002C, and HH-GG26-003C). Each hole was targeting potential tungsten and gold mineralisation south of Golden Gate South.
HH-GG26-001C, HH-GG26-002C, and HH-GG26-003C are centred approximately 500 metres south of the 2025 drilling area at Golden Gate South (HH-GG25-009C & 010C) (Figure 3).
Highly encouraging sulphide mineralisation (pyrite, arsenopyrite) associated with intense alteration of a granite, together with interpreted large-scale shearing and brecciation and areas of intense veining, have been observed in HH-GG26-001C, HH-GG26-002C (Figure 4), and HH-GG26-003C.
These features are present in well mineralised holes at Golden Gate North and at Golden Gate South.
These three drill holes are the first of the Company’s large 2026 Golden Gate Drill Program, comprising up to 13,700 planned metres (45,000 ft) of diamond core drilling, and 45 planned holes. The Drill Program is targeting tungsten and gold mineralisation known at Golden Gate.
A second MP1500 diamond core drill rig has arrived on site and is expected to be drilling early next week.
Golden Gate is located within RML’s Horse Heaven Antimony-Tungsten-Gold-Silver Project in Idaho, USA, immediately adjacent to the recently permitted Perpetua Resources’ Stibnite Gold Project.
Bill Breen, Technical Lead Geologist, stated: “I’m tremendously excited by the style and extent of mineralisation and alteration observed in core of our very first holes of the current program. This is simply because this style of mineralisation elsewhere at Golden Gate is associated with significant gold and tungsten mineralisation. The fact that these holes are drilled in a previously undrilled area, some 500 metres south of the gold mineralisation identified in the southern-most holes in last year’s drill program, only adds to the positive weight of these initial results .”
Gold Mineralisation – Scale: The drill program has started south of the Golden Gate South target. The same program will include areas north of the Golden Gate North target. There is very significant scalability combining both target areas, especially where such mineralisation is open-ended in all directions.
Tungsten Mineralisation: Drilling is also targeting tungsten mineralisation known at Golden Gate South, including a large 500m x 600m coincident gold and tungsten soil anomaly. Later drilling is designed to test extensions of this gold-tungsten soil anomaly and also to further test extensions of mineralisation historical mined. Tungsten was previously mined at the Golden Gate, most recently in 1980.

Mineralisation includes disseminated and massive dark sulphides of pyrite (2-10%) and arsenopyrite (1-20%) in association with quartz veins and sericitic altered quartz feldspar intrusive.
Middle Image: Photo of drill core sample from Drillhole HHGG26-001C 59.5-60.5m (195 ft to 199 ft) downhole depth showing a section of highly altered and mineralised drill core. Mineralisation includes disseminated and veinlets of pyrite (1-5%) and arsenopyrite (0.5-5%) in association with fractured quartz veins and sericitic altered quartz feldspar intrusive.
Right Image: Photo of drill core sample from Drillhole HHGG26-00C 42-43.5m (137 ft to 142 ft) downhole depth showing asection of highly altered and mineralised drill core. Mineralisation includes disseminated and veinlets of pyrite (0.5-4%) and arsenopyrite (0.5-3%) in association with quartz veinlets and sericitic altered quartz feldspar intrusive.
Cautionary Statement: Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations.
The Company notes that visual observations pertaining to the percentage levels of sulphide minerals pyrite and arsenopyrite were estimated by qualified geologists in the field who are familiar with this style of mineralisation. Such percentages were based on the whole rock estimates.
The Company anticipates assay results for these core sections, and other sections of core warranting assay testing to be available in 6 to 8 weeks
