Resolution Minerals Completes Record Drill Program With 39 Gold and Tungsten Results Due
Key Takeaways
- Resolution Minerals has completed its largest-ever exploration program at Horse Heaven, finishing 42 diamond core holes totalling 12,236 metres at the Golden Gate prospect in Idaho.
- 39 holes are awaiting assay results for gold and tungsten, to be released progressively over coming months — the single most important near-term catalyst for the stock.
- The first three 2026 holes have already confirmed discovery status at Golden Gate South, extending gold mineralisation at least 2,000 metres south of Golden Gate North.
- The best 2026 intercept to date — HH-GG26-003C — returned 305.7m @ 0.64 g/t Au from surface, with a higher-grade zone of 17.25m @ 1.19 g/t Au, building on 2025's standout result of 253m @ 1.5 g/t Au.
- RML began trading on NASDAQ on 9 September 2026 as an ADR at a 200:1 ratio, broadening its reach to US investors and institutions as critical mineral supply chain interest intensifies.
2026 drill program complete at Horse Heaven as assay results loom
Resolution Minerals has completed its largest-ever exploration program at the Horse Heaven Project in Idaho, USA, finishing 42 diamond core holes for a total of 12,236 metres (40,144 ft) at the Golden Gate prospect. With the drilling work now done, investor attention shifts to the results: 39 holes are awaiting assay for gold and tungsten, with results expected to be released progressively over coming months.
Craig Lindsay, CEO of US Operations
“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… This work marks a major step forward in the development of the project.”
The drilling phase is complete. The data phase is about to begin.

What the drilling targeted — and what’s already been found
The 2026 program targeted both gold and tungsten mineralisation across Golden Gate North and Golden Gate South. Three holes from this year’s campaign have already returned assay results, and the numbers from both the 2025 and 2026 programs give a clear sense of what the remaining 39 holes may be chasing.
Best 2026 intercept to date:
- HH-GG26-003C: 305.7m @ 0.64 g/t Au from surface, including 17.25m @ 1.19 g/t Au from 264.85m
Best 2025 intercepts:
- HH-GG25-003C: 253m @ 1.5 g/t Au
- HH-GG25-001C: 189.2m @ 1.30 g/t Au, including 70.8m @ 2.24 g/t Au from 128.8m
Results from the first three 2026 holes have extended gold mineralisation at least 2,000 metres south of Golden Gate North, confirming “discovery status” at Golden Gate South. That is a significant footprint expansion built on just three holes — the remaining 39 results will define how large this system could be.
On the tungsten side, scheelite (the tungsten ore mineral) has been visually identified in drill core using shortwave ultraviolet light across multiple holes, confirming tungsten potential alongside the gold. All core has been logged and photographed, and the final drill hole samples are expected to be dispatched for multi-element analysis within the week following the announcement.
Tungsten development at Golden Gate carries additional historical weight: the site has prior production history, and scheelite identified in recent core confirms the modern exploration program is building on a mineralised system with established precedent.
Program scale at a glance
| Program | Holes Completed | Total Metres | Key Targets | Status |
|---|---|---|---|---|
| 2025 (Phase 1) | 14 | 3,780m (10,100 ft) | Gold mineralisation | Results reported |
| 2026 | 42 | 12,236m (40,144 ft) | Gold and tungsten mineralisation | 39 holes awaiting assay |
Why tungsten and antimony put Horse Heaven on the US radar
Tungsten and antimony are both classified as critical minerals by the US government, meaning domestic supply is considered a national security priority.
The US currently relies heavily on imports of both metals, which is why projects capable of producing American-made tungsten and antimony are attracting significant attention from government agencies and investors alike. RML’s stated goal is to develop Horse Heaven as a potential supplier of American-made tungsten and antimony to address US critical mineral supply chain security.
The project’s strategic positioning reinforces this angle. Horse Heaven is immediately adjacent to Perpetua Resources’ Stibnite Gold Project, a large, recently permitted antimony-gold project in Idaho. The proximity places Horse Heaven within an emerging critical minerals corridor in the region.
The Antimony Ridge vein system sits within the same Horse Heaven land package and adds a structurally distinct layer to the project, with antimony-silver veining that reinforces the critical mineral credentials RML is building across the Idaho corridor.
Both the Golden Gate and Antimony Ridge prospects have received FAST-41 Transparency Coverage from the US Permitting Council. FAST-41 is a federal framework designed to improve coordination and transparency in the environmental review and permitting process for major infrastructure projects. The coverage is expected to accelerate permitting timelines for an ongoing permitting programme at both prospects and across the broader Horse Heaven project.

NASDAQ debut and what’s next for investors
RML began trading on NASDAQ on 9 September 2026 as an American Depositary Receipt (ADR) at a ratio of 200:1. An ADR allows US investors to buy shares in a foreign-listed company through a US exchange, without needing to access the ASX directly. On its first day of trading, the stock achieved its highest-ever value traded, reflecting a strong initial reception from US market participants.
The elevated US presence is expected to benefit RML as it develops Horse Heaven within the US critical minerals supply chain narrative, broadening its reach to US investors, institutions, and government organisations.
The key near-term watchpoints for investors are:
- Assay results from 39 holes covering gold and tungsten, to be released on a rolling basis over coming months
- Final drill hole samples dispatched for multi-element analysis within the week of the announcement
- Continued NASDAQ trading and US investor engagement as the results flow
The volume and quality of assay results arriving over the coming months will be the primary catalyst for RML’s near-term newsflow. With the largest exploration programme ever run at Horse Heaven now complete, the data phase is where the story either accelerates or recalibrates.
