Stillwater Critical Minerals Expands 2026 Exploration Program and Provides Project Update

Stillwater Critical Minerals Corp. has launched its largest exploration program to date at the Stillwater West project in Montana, adding a third drill rig and mobilizing field crews. The company is currently in the final stages of its updated 2026 Mineral Resource Estimate, which incorporates results from multiple drilling campaigns and expanded geological modeling.

To de-risk the project, Stillwater Critical Minerals has established strategic technical partnerships with Fleet Space Technologies for passive seismic Ambient Noise Tomography and Simcoe Geoscience for infill surface Induced Polarization lines. Primary objectives include expanding near-surface resources at Chrome Mountain and Iron Mountain by targeting higher-grade nickel-copper-PGE sulphide mineralization, as well as testing new zones in the lower Stillwater Igneous Complex.

The project hosts 1.6 billion pounds of nickel, copper, and cobalt; 3.8 million ounces of platinum, palladium, rhodium, and gold; and 2.3 billion pounds of defined chromium. Stillwater Critical Minerals benefits from proximity to Sibanye-Stillwater’s producing operations, leveraging existing infrastructure, power, water, rail, and skilled labor.

Stillwater Critical Minerals Corp. (PGE) released details on July 9, 2026, confirming the mobilization and technical scope of its 2026 drill program. This announcement serves as an operational follow-up to the program previously announced on June 10, 2026, and June 15, 2026. The company is adding a third rig and engaging geophysical partners, actions that align with management’s stated plan to feed the upcoming H1 2026 Mineral Resource Estimate (MRE).

The release introduces no new material surprises, valuation changes, or strategic shifts. Instead, it reinforces the existing exploration timeline and capital deployment strategy. Because drill program updates are routine and immediate price-sensitive data—specifically assay results—remains pending, the market impact is expected to be incremental at best.

Stillwater Critical Minerals Corp. (PGE) is an exploration-stage company focused on securing critical mineral supply in the USA. Its flagship asset is the 100%-owned Stillwater West Project in Montana, located within the Stillwater Igneous Complex adjacent to Sibanye-Stillwater’s producing mines. The project targets ten U.S. critical minerals: nickel, copper, cobalt, palladium, platinum, rhodium, gold, chromium, ruthenium, and iridium.

The company’s portfolio also includes a 49% interest in the Drayton-Black Lake project in Ontario, the Kluane PGE-Ni-Cu project in Yukon, the Duke Island project in Alaska, and the Yankee-Dundee project in British Columbia. Stillwater Critical Minerals is in the exploration and development phase, with no production history or economic studies completed to date.
