HIGHER GRADE GOLD INTERCEPTS OF 1M @ 14.8 G/T Au INDICATING FEEDER ZONES
HIGHLIGHTS
- Gold assays returned from a further three holes at Golden Gate South: Gold assay results from a further three drillholes have been returned from the southern-most section (drill fence) at Golden Gate South within Horse Heaven Project in Idaho USA, comprising HH-GG26-004C, 005C and 006C.
- Highest gold grades to date on same section as previous wide intercepts of gold mineralisation: Individual drill samples show the highest gold grades recorded to date in drilling at Horse Heaven in drill holes HH-GG26-004C and 005C, suggesting higher grade “feeder zones” (Figure 1, 2).
- Best gold intercept downhole: 1.0m @ 14.8 g/t gold (Au) from 62.1m in HH-GG26-004C;
- Also high grade interval of: 1.0m @ 7.0 g/t Au from 58.05m in HH-GG26-005C; with
- Results confirm a ~600-metre-wide gold mineralised zone at Golden Gate South: Significant gold mineralisation has been identified in all six diamond core drill holes on the southernmost drill section (drill fence), although less continuous on the western side, extending gold mineralisation to a zone approximately 600 metres wide at Golden Gate South (Figures 1,4). New higher grade feeder zones suggest new areas and targets for gold mineralisation.
- Most continuous new gold intercept of 10.2 metres @ 1.83 g/t Au from 58.05m downhole in drill hole HH-GG26-005C;
- Also gold intercept of 7.2 m @ 2.35 g/t Au from 58.1m in drillhole HH-GG26-004C;
- Follows previously reported gold intercept downhole of 305.7m @ 0.64 g/t Au from surface in drill hole HH-GG26-003 (see ASX announcement 24 August 2026).
- Initial tungsten assays and further gold results awaited to define mineralisation: Assays pending for 36 drill holes that targeted a combination of both gold and tungsten mineralisation at Golden Gate South.
- Background gold story developing while advancing critical minerals (tungsten – antimony): Assays results from the first six drillholes demonstrate a developing gold project, with a new gold discovery, while the tungsten and antimony projects are advancing at Horse Heaven Project.
September 15, 2026 (Source) — Resolution Minerals Ltd (ASX: RML; NASDAQ: RML) (“Resolution” or the “Company”) reports further gold assays from another three drill holes, revealing the highest gold grades to date in drilling at RML’s 100% owned Horse Heaven Antimony-Tungsten-Gold-Silver Project (“Horse Heaven”), Idaho, USA. The results extend the gold mineralised zone to approximately 600-metre-wide at the recent discovery of near-surface gold mineralisation at Golden Gate South (Figure 1, 4).
Assays were received for three drill holes HH-GG26-004C, HH-GG26-005C and HH-GG26-006C, all drilled in the same east-west drill section (drill fence) as previously reported drill holes HH-GG26-001C, 002C and 003C at the southern-most end of Golden Gate South (Table 1).

Results extend gold mineralisation on same drill section
Results extend the gold mineralised zone at Golden Gate South to approximately 600-metres-wide.
Significant gold mineralisation has been identified in all six diamond core drill holes on the southernmost drill section (drill fence), although less continuous on the western side (Figures 1,2,4).
Most continuous new gold intercept of 10.2 metres @ 1.83 g/t Au from 58.05m downhole in drill hole HH-GG26-005C and 7.2 m @ 2.35g/t Au from 58.1m downhole in drillhole HH-GG26-004C. This follows previously reported wide zones of gold mineralisation downhole (see ASX announcement 24 August 2026), including:
Drill hole HH-GG26-003C: 305.7 metres @ 0.64 g/t Au from surface;
Including: 17.25m @ 1.19g/t Au from 264.85m downhole;
Drill hole HH-GG26-002C: 32.6m @ 0.49 g/t Au from surface; and
87.87 m @ 0.52 g/t Au from 48.97m-136.84 m downhole
Drill hole HH-GG26-001C: 49.5m @ 0.58 g/t Au from surface.
Craig Lindsay, Resolution’s CEO of US Operations, stated:
“The assay results continue to show a wide gold mineralised zone at Golden Gate South, with high grade zones that may indicate something more – and all of this provides additional support to our view that mineralisation extends continuously from Golden Gate South to Golden Gate North. More results should be available soon. The gold story is developing well while we advance the critical minerals of tungsten and antimony in tandem.”
New higher grade feeder zones suggest new areas and targets for gold mineralisation
The higher-grade results are noticeably different in style to the wide gold mineralised zones, which suggests higher grade “feeder zones”. Potential exists to locate broad gold mineralised zones adjacent to these feeder zones.
All six drill holes reported to date were designed to test the southern extension of the Golden Gate Shear Zone, which at this location is developed within sheared and faulted Cretaceous granodiorite of the Idaho Batholith. The different drill orientations were selected to evaluate the geometry and geological controls of the target zone. Gold mineralisation appears to be related to steeply dipping features that splay off the key regional structure, the Golden Gate Shear Zone.
The drill holes often have long low-grade sections in the deeper part of the drill holes. The Company is drill testing new areas. Drilling was designed that each drill hole pierced the maximum width in a drill section to ensure that the entire length was tested for parallel veins adjacent to the key regional structure, the Golden Gate Shear Zone.
Outcomes of the gold mineralisation intersected to date
Assays results from the first six drillholes demonstrate a developing gold project, with a new gold discovery, while the tungsten and antimony projects are advancing at Horse Heaven Project.
Objectives of the 2026 Drill Program
The objective of RML’s large 2026 Golden Gate Drill Program was to target and define the scale and extent of tungsten and gold mineralisation at Golden Gate. The 2026 drill program was recently successfully completed, with 42 diamond core holes drilled for 12,236m (40,144 ft) as part of the Horse Heaven Project. The average hole depth is approximately 290m. 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.
Initial tungsten assays and further gold results awaited to define mineralisation
Assays pending for 36 drill holes that targeted a combination of both gold and tungsten mineralisation at Golden Gate South.
