Resolution Minerals Ltd (RML.AX) Drill Program Progressing well at Horse Heaven Project

Adelaide, July 1, 2026 AEST (ABN Newswire) - Resolution Minerals Ltd (ASX:RML) (NC3:FRA) (RLMLF:OTCMKTS) announces that a total of sixteen diamond core holes have been drilled at the Golden Gate South Prospect, for a total of 4,470m. A third of the total planned drill holes have been completed in the planned 13,700 metre-program (45,000 ft) at Horse Heaven, Idaho, USA (Figure 1*).

HIGHLIGHTS

- Sixteen holes completed at Golden Gate South: Sixteen diamond core holes have been drilled to planned total depths at the time of this announcement. These include HH-GG26-001 to 007, and HH-GG26-010 to HH-GG-018.

- Total metres drilled at Golden Gate South: A total of 4,470m has been drilled across completed drill holes. The average hole depth is approximately 279m.

- Core logging and sample dispatch: All the drilled core in completed holes has been logged. Samples from HH-GG26-001 to HH-GG26-004 have been dispatched for multi-element analysis.

- Two drill rigs: The planned 2026 Golden Gate drill program, of up to 13,700 metres (45,000 ft) in up to 45 drill holes, is progressing well with two drill rings on site. Approximately one third of the drilling has been completed.

- Aim to define scale of gold mineralisation: The drill program is designed to define the scale and extent (along strike and at depth) of gold mineralisation at Golden Gate North and Golden Gate South, as mentioned in RML's previous announcement (ASX announcement 30 April 2026).

- Target tungsten mineralisation: The drilling program is 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.

Holes completed to date include: HH-GG26-001, HH-GG26-002, HH-GG26-003, HH-GG26-004 (refer also to Figure 2), HH-GG26-005, HH-GG26-006, HH-GG26-007, HH-GG26-010, HH-GG26-011, HH-GG26-012, HH-GG26-013, HH-GG26-014, HH-GG26-015, HH-GG26-016, HH-GG26-017, and HH-GG-018 (Table 1*) (Figures 3 and 4*).

Core logging is progressing, recording geology, alteration and mineralisation. All the metres drilled have been logged (and photographed) by Company geologists or full-time contractors. All core from the completed holes has been inspected to identify scheelite, a tungsten ore-mineral. Where scheelite has been identified, detailed core photos and intervals have been recorded.

Two large sample-batch of core samples have been despatched for multi-element analysis. These include all samples for holes HH-GG26-001 to HH-GG26-004.

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

"I am exceedingly pleased with the drill rate we are achieving at Golden Gate South. All core needs to be carefully logged, including but not limited to lithology, alteration and mineralisation, then appropriately sampled. On this front, we are up to date. We have also submitted two large batches of samples,for which we are certainly looking forward to receiving the results."

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. This very positive drilling update follows the selection of Antimony Ridge for FAST-41 Transparency Coverage from the US Permitting Council, announced on 8 April 2026.

Objectives of the 2026 Drill Program and Drill Permit

The objectives of RML's large 2026 Golden Gate Drill Program, of up to 13,700 metres (45,000 ft) of diamond core drilling, across up to 45 holes, is 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.
