 Antimony focus: Resolution Minerals partners with Kingston Process Metallurgy - ICYMI



Resolution Minerals and Kingston Process Metallurgy Join Forces

Resolution Minerals Ltd (ASX:RML) has made a decisive move in advancing its U.S. antimony strategy by partnering with Kingston Process Metallurgy (KPM), a Canadian leader in process development and metallurgical testing. KPM will conduct comprehensive test work on ore samples from Resolution’s Horse Heaven Project in Idaho, USA. The study will include chemical assays, mineralogical analysis, and bench-scale concentration testing to create an optimal “flowsheet” for processing antimony-rich ore. The collaboration aims to establish a clear, commercially viable path from exploration to production, ultimately contributing to a secure U.S. domestic supply chain for this vital mineral.


Exceptional Grades from Antimony Ridge Strengthen Project Outlook

Resolution’s Antimony Ridge prospect has delivered outstanding surface rock chip results, with grades reaching up to 49.8% antimony (Sb), 1,420 g/t silver (Ag), and 3.12 g/t gold (Au). These remarkable grades not only enhance the project’s attractiveness but also support a strong economic case for downstream processing. The high-grade mineralization positions Horse Heaven as a standout project in North America’s critical minerals landscape, offering a potential competitive edge in cost efficiency and resource quality.

Aligning with U.S.–Australia Critical Minerals Strategy

The partnership between Resolution and KPM aligns perfectly with the broader U.S.–Australia critical minerals agenda, which aims to secure stable and ethical supply chains for materials essential to defence, renewable energy, and advanced manufacturing. Antimony has been recognized as a critical mineral by the U.S. government due to its applications in flame retardants, semiconductors, and military-grade alloys. By conducting metallurgical work in North America and targeting U.S. processing facilities, Resolution Minerals is positioning itself as a strategic contributor to the Western critical minerals ecosystem.

Corporate Expansion and U.S. Market Ambitions

In a parallel move to strengthen its corporate structure, Resolution Minerals has appointed Tribeca Capital as its corporate adviser. The appointment signals a major step toward expanding in the U.S. market and possibly listing on the Nasdaq by early 2026. Tribeca will assist in investor engagement, M&A advisory, government relations, and strategic partnerships. Furthermore, Tribeca has backed Resolution through a A$2 million placement, showcasing investor confidence in the company’s downstream antimony strategy and its long-term growth potential in the North American market.

Next Steps, Key Risks, and Outlook

The next major milestone for Resolution will be the release of metallurgical test results from KPM, expected soon. These findings will inform bulk sampling, pilot-scale processing, and final product design. Resolution also plans to pursue non-dilutive U.S. government funding opportunities and explore offtake agreements with industrial partners. However, investors should remain mindful of potential challenges, such as metallurgical complexities, regulatory delays, and market fluctuations in antimony prices.
