I am pleased to announce the completion of all 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.
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 drill holes, with results to be reported over the 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:
- Best gold intercept this year to date: 305.7 metres @ 0.64 g/t gold (Au) from surface in HH-GG26-003C (ASX announcement 24 August 2026).
- Best gold intercepts in last year’s drill program were: 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.
