Resource Estimate
Stillwater Reports Rhodium Results and Highlights Defined Chromium at Stillwater West, Montana, USA
Updated Resource Estimate Progress

Executive Summary
- Stillwater Critical Minerals reported rhodium (Rh) assay results from its 2025 resource expansion drill campaign at the Stillwater West project in Montana.
- The company defined a significant chromium resource of 2.3 billion pounds (Blbs) contained chromium at the 100%-owned Stillwater West project.
- Rhodium drilling intercepts confirmed widespread mineralization, with holes CM2025-01 and IM2025-01 showing grades up to 0.167 g/t Rh over 1.22m.
- Results will be incorporated into an updated NI 43-101 Mineral Resource Estimate (MRE) targeted for release in the first half of 2026.
- The five-year average and current spot price for rhodium is approximately US$10,000/oz, highlighting the economic potential of the defined mineralization.
Material Impact
- The news confirms progress toward the updated MRE announced in October 2025, which was scheduled for H1 2026.
- Defining a specific chromium resource of 2.3 Blbs adds material value to the project's critical mineral portfolio beyond nickel and PGEs.
- Rhodium is ranked as a priority critical mineral by the U.S. government for potential GDP disruption, enhancing the strategic profile of the asset.
- However, this news is part of an ongoing drill campaign leading to a known milestone (the H1 2026 MRE), making it largely expected rather than a surprise discovery.
- The stock price has declined significantly from January highs ($0.62) to current levels ($0.30), suggesting the market may have already priced in exploration progress or is awaiting the final resource estimate.
