Resolution Minerals Ltd (ASX: RML; OTCQB: RLMLF) (“Resolution” or the “Company”) has announced that it has been officially requested by His Excellency, The Hon Dr Kevin Rudd AC, the Australian Ambassador to the United States, to provide a detailed briefing on its Horse Heaven Gold-Antimony-Tungsten Project in Idaho, U.S.

The request comes in advance of the upcoming meeting between Australian Prime Minister Anthony Albanese and U.S. President Donald Trump in Washington D.C. on 20 October 2025, where critical minerals are set to feature prominently in bilateral discussions.
The inclusion of Resolution’s Horse Heaven Project in such high-level diplomatic exchanges underscores both the Project’s strategic importance and Australia’s growing role in securing responsible mineral supply chains for its key allies.
A Strategic Project with Global Significance
The Horse Heaven Project is located adjacent to Perpetua Resources’ Stibnite Antimony & Gold Mine in Idaho, a development with a market capitalisation of around A$3 billion. This proximity to a proven, world-class operation reinforces the potential of Horse Heaven to become a major player in the supply of Gold, Antimony, and Tungsten—all of which are listed on the U.S. Critical Minerals List.
The Project comprises 729 federal lode mining claims covering over 14,580 acres. It hosts past-producing mines and several high-priority target zones, including the Golden Gate and Antimony Ridge prospects. Historical production has already demonstrated mineralisation of Gold, Antimony, and Tungsten, and current drilling programs are confirming and expanding these results.
The Project’s significance lies in its capacity to contribute to the U.S. ambition of establishing a secure domestic supply of antimony, an element critical to defence, semiconductors, flame retardants, and energy storage.
CEO’s Statement on Diplomatic Recognition
Resolution’s CEO of U.S. Operations, Craig Lindsay, highlighted the importance of the recognition: “Resolution Minerals appreciates the opportunity to brief Ambassador Rudd on the Horse Heaven Project ahead of the Prime Minister’s visit to Washington.”
He further added:
“Horse Heaven is a significant Australian-led project in the United States, with historical and potential future production of gold, antimony and tungsten, which are all critical to industrial and defence applications. The briefing reflects the constructive cooperation between Australia and the U.S. on the development of secure, transparent critical mineral supply chains.”
“We look forward to contributing to this dialogue and providing an update on our progress of our work in Idaho.”

Antimony Market Dynamics
The timing of this recognition coincides with strong growth in the global antimony market. The global antimony market was valued at USD 2.17 billion in 2023 and is projected to reach USD 3.30 billion by 2030, expanding at a CAGR of 6.1% (2024–2030), as per the findings of Grand View Research.
Key insights include:
- Asia Pacific remained the largest revenue-generating region in 2023.
- Trioxides accounted for the largest revenue share by type.
- Flame retardants represented the leading application segment.
With the U.S. currently heavily reliant on imported antimony, projects such as Horse Heaven and its neighbour Stibnite are of strategic importance in reducing dependency and securing onshore supply.
Gold Price Surge Supporting Project Economics
The Horse Heaven Project also benefits from favourable gold market conditions. As of 14 October 2025, gold was trading at USD 4,139 per ounce (AUD 6,356.93/oz), with prices recording a 12.49% increase over the past month and a 57.71% rise year-to-date.
This sustained rally in gold prices, coupled with demand for antimony and tungsten, strengthens the economic case for Horse Heaven’s development and enhances Resolution’s long-term growth prospects.
U.S. Strategic Push for Critical Minerals
The U.S. Government has identified antimony and tungsten on its 2025 Draft List of Critical Minerals. These elements play vital roles in military applications, advanced electronics, and clean energy infrastructure.
Washington is moving to accelerate the development of domestic supply through expedited permitting, grants, and equity participation. This policy backdrop creates a favourable environment for Horse Heaven, with Australia seen as a trusted partner in advancing secure supply chains.
Project Development and Next Steps
Resolution has already completed its Phase 1 drilling campaign at Horse Heaven and is awaiting results. Additional exploration programs, including stream sediment surveys, mapping, and rock chip sampling, are underway, with results expected to be released progressively to the market.
The Project’s location near the town of Cascade, Idaho, provides access to upgraded infrastructure being developed for the adjacent Stibnite Mine. Historically, the region has been a prolific source of critical minerals, particularly during World War II and the Korean War, when Stibnite alone accounted for 90% of U.S. antimony production.
Growing Recognition at the Diplomatic Level
The briefing request from Ambassador Dr. Kevin Rudd represents a milestone for Resolution Minerals. It signals formal acknowledgement of the Project’s relevance not only to the U.S. but also to the strategic interests of the Australian Government.
By aligning itself with Australia’s national strategy to strengthen critical minerals cooperation with the U.S., Resolution positions itself at the centre of one of the most geopolitically significant sectors in modern industry.
Investors Outlook
Resolution Minerals’ shares have shown strong market performance, reflecting investor confidence in the Company’s strategic positioning. As of 14 October 2025, Resolution shares traded at $0.062, up 37.78% on the day, with a market capitalisation of $111.5 million.
Performance highlights:
- 1 Week: +44.19%

- YTD 2025: +416.67%
- 1 Year: +287.50%
- Outperformed the sector by +273.55% over one year
- Outperformed ASX 200 by +276.76% over one year
This exceptional run reflects growing investor awareness of the strategic importance of Antimony and the Horse Heaven Project’s potential role in securing supply.
With global antimony demand set to rise sharply, favourable gold prices, and strong U.S.–Australia government alignment, investors are positioning Resolution Minerals as a critical player in the next phase of critical minerals development.
