Stillwater Critical Minerals Reports on Rhodium and Chromium Resources

Stillwater Critical Minerals Corp. recently announced significant rhodium assay results from its 2025 drill campaign in Montana. These results highlight widespread rhodium mineralization at potential co-product levels within the Chrome Mountain and Iron Mountain resource areas. The assays, reaching up to 0.167 g/t Rh, demonstrate the district-scale nature of the polymetallic system.

The current Mineral Resource Estimate, which includes 115,000 ounces of rhodium, is poised for an update in the first half of 2026. This estimate underscores Stillwater West as the largest known rhodium and chromium resource in the United States.

Rhodium is recognized as a critical mineral in the U.S., essential for emissions control and defense-related applications. The project also includes significant amounts of nickel, copper, cobalt, and platinum group metals, highlighting its strategic importance, particularly due to the U.S.'s reliance on imports for such critical minerals.
