Stillwater Critical Minerals Engages Mine Technical Services to Complete an Updated Mineral Resource Estimate at Stillwater West in Montana, USA
None
On October 27, 2025, Stillwater Critical Minerals announced it has engaged Mine Technical Services (MTS) to complete an updated NI 43-101 Mineral Resource Estimate (MRE) for its flagship Stillwater West project in Montana. The company reaffirmed the timeline for completion in the first half of 2026.
The updated MRE will incorporate data from 14 drill holes (5,781 meters) from the 2023 and 2025 exploration programs. The company also confirmed that the 2025 drill campaign is now complete, with all assay results pending. Management highlighted that the team from MTS was responsible for defining the resources at Ivanhoe's Platreef Mine, drawing a parallel between the geology of the two projects.
This news is a procedural update that confirms the company is executing its stated plan. The timeline for the updated MRE in H1 2026 was previously announced on September 15, 2025, so this news meets expectations but does not introduce a new material catalyst.
The positive aspects are: - Execution: The company is moving forward on a key milestone. Engaging a reputable firm like MTS, known for its work on similar large-scale polymetallic deposits, adds credibility to the upcoming resource update. - Drilling Completion: The completion of the 2025 drill program is a significant operational milestone.
However, the impact is routine and not material for the following reasons: - No New Data: The release contains no new exploration data. The market is still awaiting the assay results from the 5,781 meters of drilling, which are the true near-term catalyst. The qualitative statement about intersecting "near-surface magmatic sulphide zones" is encouraging but standard language for an exploration company; it is not a substitute for assay results. - Expected Timeline: The H1 2026 target for the MRE is unchanged.
Overall, the news is a positive confirmation of progress, but the key value driver remains the pending drill results. The market has already priced in the expectation of an updated MRE; this news simply formalizes the process.
Stillwater Critical Minerals Corp. is a Canadian mineral exploration company focused on its flagship Stillwater West project in Montana, USA. The project is a large-scale Nickel-Copper-Cobalt-PGM + Gold deposit located adjacent to Sibanye-Stillwater's producing PGM mines. The company's strategy is to define a large, polymetallic resource of critical minerals in a top-tier US jurisdiction, leveraging favorable geology analogous to South Africa's Platreef district. The project hosts ten commodities designated as critical by the U.S. government.
The company also holds non-core assets, including the Kluane project in Yukon and royalty/equity interests in the Drayton-Black Lake and Duke Island projects.
The Stillwater West project has a NI 43-101 Inferred Mineral Resource (January 2023) of 1.6 billion pounds of nickel, 1.1 billion pounds of copper, and 3.8 million ounces of PGE+Au. The company is actively drilling to expand this resource. All claims on the Stillwater West project are subject to a 2% Net Smelter Return (NSR) royalty, which can be bought down to 1%.
