Property-Wide Geophysical Survey Completed With Demonstraton Continuity Of  Mineralization

VANCOUVER - Stillwater Critical Minerals Corp. reported the completion of a property-wide geophysical airborne survey and a breakthrough in 3D geologic modeling of the lower Stillwater Igneous Complex. This new data will drive continued advancement of the project including drill campaigns and the expansion of mineral resources, among other objectives at its flagship Stillwater West Ni-PGE-Cu-Co + Au project in Montana.

Property-wide geophysical surveys completed in September 2024 informed the first-ever detailed 3D geologic model of the lower Stillwater Igneous Complex. The model demonstrates continuity of mineralization across the 9.5-kilometer length of lower Stillwater Igneous Complex which hosts the Company's current resources in five deposits at Stillwater West project. Historically, continuity of mineralization across the entire surface expression of the magmatic layers of the Stillwater Igneous Complex has been demonstrated primarily by Sibanye-Stillwater's J-M Reef deposit, a high-grade PGE-bearing nickel-copper sulphide deposit that spans more than 40km and supports the highest-grade palladium-platinum mines in the world.

Stillwater's current resources of 1.6 billion pounds of nickel, copper and cobalt, and 3.8 million ounces of palladium, platinum, rhodium, and gold are hosted in five deposits that remain open for expansion along trend and at depth across 9.5-kilometers at the center of the 61-square-kilometer Stillwater West project, which is adjacent to Sibanye-Stillwater along approximately 32km of strike within the Stillwater Igneous Complex.

President and CEO, Michael Rowley, said, "The team's work this year regarding both the airborne survey and also the detailed geologic model confirm the expansion potential we see in several possible mining scenarios at Stillwater West and inform our campaigns to reach that objective. Together we have successfully leveraged a substantial database including approximately 40,000 meters of drilling to date to complete the first ever geologic model of the lower part of this famously productive and metal-rich American mining district, with a focus on magmatic nickel-copper sulphide mineralization. That wealth of data, combined with Glencore plc's backing and in-house expertise from similar geology in South Africa's Bushveld Igneous Complex, has positioned us exceptionally well with robust inventories of nickel, copper, cobalt, platinum group elements and chromium in an active American mining district at a time when the US is aggressively looking to diminish the current heavy import reliance of nine of the commodities we have inventoried."
