Resolution Minerals Ltd (RML.AX) Drill Program Successfully Completed at Horse Heaven

Adelaide, Sep 11, 2026 AEST (ABN Newswire) - Resolution Minerals Ltd (ASX:RML) (NC3:FRA) (RLMLF:OTCMKTS) announced that a total of forty two (42) diamond core holes have been completed at the Golden Gate North and Golden Gate South Prospects, for a total of 12,236m (40,144 ft) to finish the planned 2026 drill program at the Horse Heaven antimony-tungsten-gold-silver project ("Horse Heaven"), Idaho, USA (Figure 1*).

Core logging is complete, recording geology, alteration and mineralisation. All drill metres have been logged (and photographed) by Company geologists or full-time contractors, including inspection by UV light to identify scheelite, a tungsten ore-mineral.

HIGHLIGHTS

- Forty-Two drill holes completed at Horse Heaven's Golden Gate Prospect: 42 diamond core holes have been drilled for 12,236m (40,144 ft) successfully completing the planned 2026 drill program at Golden Gate, part of the Horse Heaven Project. The average hole depth is approximately 290m.

- Assay results pending on 39 holes: Assay results pending for gold and tungsten from 39 drillholes, with results to be reported over coming months as they are received.

- Wide intercepts of gold mineralisation previously reported: Gold mineralisation has been previously reported from Golden Gate from the first three holes of the 2026 drill program and the 2025 program, including:

o Best gold intercept this year to date: 305.7 metres @ 0.64 g/t gold (Au) from surface in HH-GG26-003C, including 17.25m @ 1.19g/t Au from 264.85m (ASX announcement 24 August 2026).

o Best gold intercepts in last year's drill program were: 189.2m @ 1.30 g/t Au from 34.1m, in HH-GG25-001C, including 70.8m @ 2.24 g/t Au from 128.8m and 253m @ 1.5 g/t Au in HH-GG25-003C (ASX announcements 2 December 2025 & 18 March 2026).

- Major extension to gold mineralisation previously reported at Golden Gate South: Results from the first three holes released to date this year have extended gold mineralisation at least 2,000 metres south of Golden Gate North, confirming "discovery status" at Golden Gate South (see ASX announcement 24 August 2026).

- Target tungsten mineralisation: The drilling program was also designed to identify the extent of tungsten mineralisation around previous mine workings at the historical Golden Gate Tungsten mine and explore a broad tungsten anomaly in soil samples at Golden Gate South. Known scheelite occurrences in early drillholes were identified visually using a shortwave ultraviolet light (see ASX announcement 1 July 2026 and 13 July 2026).

- Core logging and sample dispatch: All the drilled core has been logged and the final drill hole samples will be dispatched for multi-element analysis within the coming week.

- NASDAQ trading successful: RML has been well-received by the US market, as demonstrated by the stock achieving its highest-ever value traded on its first day trading on NASDAQ (9 September 2026). RML.NAS is trading as an ADR (200:1), which has boosted the Company's visibility and exposure to U.S. investors, institutions and U.S. government organisations and personnel. This elevated presence in the U.S. is expected to benefit RML as it develops Horse Heaven into a potential supplier of American-made tungsten and antimony and aims to provide critical metal supply chain security to the U.S. Administration.

Craig Lindsay, Resolution's CEO of US Operations, stated:

"I am exceedingly pleased to announce the completion of all the planned drillholes at Golden Gate. We await gold and tungsten assay results from the drillhole samples with anticipation. The 2026 drill program marks the largest exploration program ever conducted at Horse Heaven. I thank the team and the drillers for this accomplishment. This work marks a major step forward in the development of the project."

Golden Gate is located within Resolution's Horse Heaven Antimony-Tungsten-Gold-Silver Project in Idaho, USA, and immediately adjacent to Perpetua Resources' Stibnite Gold Project, a large, recently permitted Antimony-Gold project. Both Golden Gate and Antimony Ridge have been selected for FAST-41 Transparency Coverage from the US Permitting Council, accelerating the permitting timelines for an ongoing permitting program at both prospects and the entire Horse Heaven project.

Wide intercepts of gold mineralisation, previously reported, with higher grade zones:

Gold mineralisation has been identified in allthree previously reported diamond core drill holes with assay results from this year's drilling, extending gold mineralisation at least 2000 metres south from Golden Gate North to Golden Gate South. The best gold intercept in this year's drilling to date shows gold mineralisation extending from surface downhole to the base of hole in drill hole HH-GG26-003C.

Drill hole HH-GG26-003C: 305.7 metres @ 0.64 g/t Au from surface;

- Including: 6.5m @ 1.33g/t Au from 62.0m downhole;
- 17.25m @ 1.19g/t Au from 264.85m downhole;

Major extension to gold mineralisation confirms discovery status at Golden Gate South

Significant pervasive gold mineralisation was identified in all three diamond core drill holes with reported assay results to date from this season's drilling. Results extended gold mineralisation at least 2,000 metres south of Golden Gate North, confirming "discovery status" at Golden Gate South. Drilling assay results, soil sampling, geophysics and geological mapping has now confirmed the discovery and presence of gold mineralisation at Golden Gate South (ASX announcement 24 August 2026).

Successful Phase 1 drilling last year (2025) for gold mineralisation

This season's drilling follows the successful Phase 1 drilling campaign in 2025, which totalled 3,780 metres (10,100 ft) across 14 drill holes. All Phase 1 drill holes intersected gold mineralisation from surface and delivered multiple broad gold intercepts, including:

- 253m @ 1.5 g/t Au (HH-GG25-003C);

- 189.2m @ 1.30 g/t Au (HH-GG25-001C);

- 265.2m @ 0.60 g/t Au (HH-GG25-002C); and

- 240.8m @ 0.64 g/t Au (HH-GG25-004C) (ASX announcements 2 December 2025 & 18 March 2026).

Drill holes targeted tungsten and gold mineralisation at Golden Gate

Drill holes have targeted both gold and tungsten mineralisation, including a significant tungsten in soil anomaly identified at Golden Gate South and around previously mined scheelite at Golden Gate North.

Scheelite is known to occur at Golden Gate (ASX Announcement 8 September 2025). In 2025 diamond core drilling scheelite is reported to occur with quartz and manganese in veins in heavily oxidised quartz-feldspar altered granite. In the Company's 2026 drill program at Golden Gate, scheelite has again been identified.

Known scheelite occurrences in the early drillholes were identified visually using a shortwave ultraviolet light (ASX announcement 1 July 2026 and 13 July 2026). The Company anticipates assay results from this core in coming weeks.

Objectives of the 2026 Drill Program

The objectives of RML's large 2026 Golden Gate Drill Program, of over 12,000 metres (40,000 ft) of diamond core drilling, across 42 holes, was to target and define the scale and extent of tungsten and gold mineralisation at Golden Gate, starting at Golden Gate South. 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.
