US antimony supply targeted by Resolution Minerals

Resolution Minerals (ASX:RML) is commencing exploration at its Horse Heaven Gold, Antimony, Silver, and Tungsten Project in Idaho, USA, with a 20-hole drilling program set to begin in August. This initiative is strategically significant given the U.S.'s complete reliance on imported antimony and aligns with a proposed $2.5 billion federal investment in critical minerals. While the project is in its greenfield stage, the board's decision to fund exploration prior to formal transaction completion signals strong internal confidence in defining potential gold, antimony, and tungsten resources, with initial assay results expected later this year and into early next.

Analysis

Resolution Minerals (ASX:RML) is launching an exploration program at its Horse Heaven Project in Idaho, a strategically significant move targeting a critical U.S. supply chain vulnerability. The United States currently lacks any domestic antimony production, relying entirely on imports, which positions this project to potentially benefit from a proposed $2.5 billion federal investment in critical minerals. While the project is at a high-risk greenfield stage, the company is proceeding with a 20-hole, 20,000-foot drilling program scheduled for August, with initial assay results expected later this year and into early 2026. A strong signal of internal confidence is the board's decision to approve capital spending on exploration prior to the formal transaction's completion. The initial exploration targets at Antimony Ridge, Golden Gate, and V2 Creek represent a small portion of the total 55-square-kilometre project area, suggesting considerable long-term upside if the maiden drilling program proves successful.

Key Decisions for Investors

• Investors should monitor the upcoming August drilling program and subsequent assay results as the primary near-term catalysts, as positive findings are essential to de-risk this greenfield asset.
• Given the project's early stage, positions should be sized for a high-risk, high-reward profile, as the company's valuation will be highly sensitive to the initial drilling outcomes.
• Consider the strategic premium associated with a potential domestic US antimony supply, as the project's alignment with stated US policy to reduce import reliance for critical minerals could attract significant government and market interest.
