Executive Summary

Stillwater Critical Minerals Corp. announced the retention of contractors and imminent mobilization of drill rigs for its largest-ever exploration and resource expansion campaign at its 100%-owned Stillwater West project in Montana.
The 2026 drill program targets expanding mid- to high-grade polymetallic sulphide mineralization within and adjacent to existing resources at Chrome Mountain and Iron Mountain.
Primary objectives include delineating higher-grade nickel-copper-PGE sulphide zones, testing new sulphide zones in the lower Stillwater Igneous Complex, and completing ground geophysical surveys to refine targets.
The campaign is explicitly designed to support an upcoming updated NI 43-101 Mineral Resource Estimate (MRE) expected in the near-term.
Strategic partner Glencore plc continues to provide strong support, aligning with U.S. critical mineral security initiatives.
The company highlighted its broader portfolio, including a 49% interest in Drayton-Black Lake (Ontario), Kluane (Yukon), Duke Island (Alaska), and a back-in right on Yankee-Dundee (BC).
Management plans to attend key industry conferences including Fastmarkets (June), Montana Mining Association (July), and the Precious Metals Summit (September).

Material Impact

Historical Context: The company has been systematically advancing its exploration programs. Previous releases in February, March, and May 2026 reported wide, high-grade Ni-Cu-Co-PGE-Au sulphide intercepts and confirmed rhodium/chromium mineralization, all feeding into the planned updated MRE.
Progression: The June 2026 mobilization is the logical next step following the successful 2025 drilling campaign and the December 2025 bought-deal financing that secured C$17 million. It confirms management's execution capability and capital deployment.
Impact on Stock: The news is positive but expected. It does not introduce new strategic partnerships, M&A, or breakthrough economic studies. The market has already priced in the exploration progress and the Glencore backing. The material impact is limited to maintaining investor interest and validating the near-term catalyst (updated MRE).
Expectations vs. Reality: Fully in line with previous guidance. No surprises in scope, funding, or strategic direction.
