Stillwater Critical Minerals – Updated MRE More Than Doubles The Mineral Resources at Stillwater West – Ongoing Infill Drilling, Future PEA

We are joined by Michael Rowley, President & CEO of Stillwater Critical Minerals (TSX.V: PGE – OTCQB: PGEZF), to provide the key metrics and takeaways from updated and expanded Mineral Resource Estimate (MRE), over double the prior resources, for its flagship Stillwater West Ni-PGE-Cu-Co + Au project in Montana, USA.   We also unpack the larger value proposition at the Stillwater West project as far as what it would mean to a major metals producer and potential suitor in a development scenario, and what it would mean for both the state of Montana and the USA overall as a domestic supply of critical minerals.

 

The updated estimate includes 805.1 million tonnes of Inferred Mineral Resources grading 0.34% total nickel equivalent (“NiTEq”) containing 4.8 billion pounds of nickel, copper and cobalt, and 7.4 million ounces of platinum, palladium, gold and rhodium in a base-case model using a 0.20% NiTEq cut-off grade.

• The resource also includes a further 29.4 million tonnes of Indicated Mineral Resources grading 0.38% NiTEq containing 190 million pounds of nickel, copper and cobalt, and 0.359 Moz of platinum, palladium, gold and rhodium.
• Higher cut-off grades at 0.35% and 0.50% NiTEq are also presented as a sensitivity representing higher-grade zones.

 

The 2026 MRE reflects a substantial advancement in the Company’s understanding of the Stillwater West mineral system, incorporating additional drilling, robust verification of historical data, refined geological and structural interpretations supported by comprehensive geophysical survey coverage, and an updated geologic and resource model. The updated estimate provides a stronger technical foundation for continued resource expansion, planned metallurgical testing and mining studies to support the advancement of one of North America’s largest undeveloped polymetallic critical mineral systems.

 

2026 Mineral Resource Estimate Highlights

 

• Resource estimate comprises 29.4 million tonnes of Indicated and 805.1 million tonnes of Inferred Mineral Resources containing 3.01 Blbs nickel, 1.52 Blbs copper, 283 Mlbs cobalt, 2.28 Moz platinum, 3.97 Moz palladium, 864 thousand ounces gold, and 310 Koz rhodium at 0.20% NiTEq cut-off.
• First definition of an Indicated Mineral Resource, marking an important milestone in the advancement of the Stillwater West project and reflecting substantially increased geological confidence.
• Significantly expanded resource estimate for priority critical minerals including nickel, copper, cobalt, and rhodium, making Stillwater West the largest known rhodium deposit in North America and the largest nickel and cobalt deposit in an active US mining district.
• Expansion of Inferred chromium resource to 6.6 Blbs confirming the Stillwater complex as one of the only past-producing and current significant resources in the United States. No economic or recovery assumptions have been made about chromium which co-occurs with the other metals, and it is not included in the NiTEq calculations.
• Four zones are modeled across the central 10-kilometers of the project area, with the updated geological model combining the previously separate CZ and Central deposits at Iron Mountain.
• Stillwater West is uniquely positioned to become a primary source of 10 commodities now listed as critical, given their location immediately adjacent to Sibanye-Stillwater’s operating mine complex in Montana.

 

Mike shares how the geological model is holding together precisely as expected, using the South African Bushveld Igneous Complex as analog, and how their five “Platreef-style” (or contact-type) Ni-Cu-Co-PGE+Au deposits may tie together in a larger sense.  3 drill rigs have been turning at both Iron Mountain and Chrome Mountain, and assays are pending from fresh drill core still coming off the mountain during the 2026 program.
