Resolution Minerals (ASX: RML) has made a decisive move to position itself at the forefront of America's critical mineral independence agenda, dispatching high-grade antimony samples grading up to 49.8% from its Horse Heaven project to Kingston Process Metallurgy for comprehensive metallurgical testing. The company has simultaneously appointed Tribeca Capital as corporate adviser to support its early 2026 NASDAQ listing and broader U.S. expansion strategy, forming a crucial part of Resolution Minerals critical mineral supply chain strategy.
The timing couldn't be more strategic. With antimony classified as a critical mineral essential for defence applications, Resolution's Horse Heaven project in Idaho's historically significant Stibnite mining district represents a rare opportunity to rebuild domestic U.S. supply chains. Recent surface sampling has delivered exceptional results, with grades reaching 49.8% antimony, 1,420 g/t silver, and 3.12 g/t gold.

The company has successfully guided numerous projects from inception to commercial production, making it an ideal partner for Resolution's ambitious timeline.
Understanding Critical Minerals: Why Antimony Matters for National Security
Antimony represents one of the most strategically important critical minerals for U.S. national security. This metalloid serves as an essential component in flame retardants, lead-acid batteries, and military applications including ammunition and defence equipment manufacturing.
Critical minerals are raw materials that are considered vital to the economic and national security of a nation but subject to supply chain vulnerabilities. These materials typically exhibit two key characteristics: they are essential for key technologies and industries, and their supply chains are dominated by a small number of countries or sources.
The strategic significance becomes clear when considering supply chain vulnerabilities. China currently dominates global antimony production, controlling approximately 60% of world supply. This concentration creates substantial national security risks for Western nations, particularly given antimony's irreplaceable role in defence manufacturing.
For investors, this supply chain dynamic creates compelling opportunities. Government initiatives to rebuild domestic critical mineral capacity, combined with potential non-dilutive funding programmes, position well-located projects like Horse Heaven to capture significant value as strategic assets rather than traditional commodity plays.
Tribeca Capital Partnership Strengthens U.S. Market Position
The appointment of Tribeca Capital as corporate adviser signals Resolution's commitment to maximising its U.S. market opportunity. Tribeca's mandate encompasses several critical areas within the Resolution Minerals critical mineral supply chain strategy framework:
Strategic Development Initiatives:
• Downstream strategy development including new processing technologies and metallurgy optimisation
• Offtake partner identification and sales agreement facilitation
• Additional acquisition opportunities including project areas, material stockpiles, and processing facilities
• Corporate M&A opportunity evaluation and execution
Market Access and Capital:
• NASDAQ listing support targeting early 2026 completion with initial F-20 Form first draft already completed
• Access to extensive global investor, broker, and institutional networks
• Government engagement utilising political relationships in Australian and U.S. spheres
"Resolution has real potential to be one of the key leaders within the US in meeting the Trump Administration's critical minerals national security agenda."

Horse Heaven Project: Past-Producing Asset Ready for Revival
The Horse Heaven Gold-Antimony-Silver-Tungsten Project occupies a premium position in Idaho's Yellow Pine Mining District, covering 5,644 hectares across 729 federal lode claims. The project's strategic location becomes even more compelling considering its shared boundary with Perpetua Resources' $2.8 billion market value Stibnite Gold-Antimony Project.
| Historical Production Data | Details |
|---|---|
| Active Production Periods | World War I, World War II through 1950s |
| Primary Target | U.S. military demand fulfilment |
| Infrastructure | 1,000m of historical trenching across 300m vertical height |
| Processing Method | High-grade ore shipped and processed off-site |
The Antimony Ridge Fault Zone represents the primary mineralisation corridor, hosting a shear-hosted antimony-gold-silver mineral system exposed across 1,000 metres of surface trenching. Recent sampling has validated the historical potential with exceptional grades including 19.15% antimony, 70.5g/t silver, and 4.65g/t gold.
The geological setting indicates a shear-hosted disseminated oxide gold system overprinted by a secondary antimony-silver system. During World War I, World War II, and through to the 1950s, antimony was produced at Antimony Ridge through a sequence of three trenches to support U.S. military demand.
