Resolution Minerals Rocks on with Tungsten Concentrate at Horse Heaven

Why It Matters

The breakthrough suggests a fast‑track path to commercial tungsten production, bolstering the supply of a critical mineral essential for defense and clean‑energy technologies. It also positions Resolution to unlock additional value from antimony and gold within the same project.

Key Takeaways

• 52.3% WO3 concentrate produced from historic stockpiles.
• Upgrade ratio of 19 times versus 1.85% WO3 feed.
• Recoveries reached up to 75.5% using gravity separation.
• Simple low‑cost processing could accelerate project timeline.
• Phase 2 drilling of 13,700 m planned for May 2026.

Pulse Analysis

The global push for clean‑energy and advanced manufacturing has heightened demand for tungsten, a metal prized for its high melting point and strength. Resolution Minerals’ Horse Heaven project in Idaho taps a legacy resource, turning low‑grade historic ore into a high‑purity concentrate. By achieving a 52.3% WO₃ grade with a 19‑fold upgrade, the company demonstrates that even modest stockpiles can meet the stringent specifications of downstream smelters, potentially shortening the path from mine to market.

Resolution’s test work leverages gravity‑based separation, a technique that exploits the density contrast between scheelite and lighter gangue minerals. The process delivered up to 75.5% recovery, indicating that the ore can be upgraded without expensive reagents or complex circuitry. This low‑cost, scalable approach not only reduces capital expenditure but also aligns with environmental expectations for minimal chemical usage. Parallel trials on antimony and gold-bearing material suggest a multi‑metal strategy, diversifying revenue streams and enhancing the project's overall economics.

Looking ahead, the upcoming 13,700‑metre Phase 2 diamond drilling campaign aims to delineate the extent of gold and tungsten mineralisation, a critical step toward a maiden resource estimate. Successful results could attract strategic partners and secure offtake agreements, especially as governments prioritize domestic sources of critical minerals. For investors, the combination of proven processing, a clear drilling roadmap, and alignment with broader supply‑chain imperatives makes Resolution Minerals a compelling watch in the evolving critical‑minerals landscape.
