## Minestarters Atlas summary

Stillwater Critical Minerals has engaged Mine Technical Services to perform an updated NI 43-101 compliant Mineral Resource Estimate for the Stillwater West project in Montana. The update, expected in H1 2026, will incorporate data from the 2023 and 2025 drilling campaigns. The project is a significant source of multiple US-listed critical minerals, including nickel, copper, and platinum group metals.

- Positive factor: Engagement of specialized technical team \(MTS\) with Platreef experience

- Positive factor: Inclusion of recent 2025 drilling data in upcoming update

- Positive factor: Strategic importance of critical minerals portfolio

- Negative factor: The announcement is about an upcoming estimate, not the release of new numbers

- Negative factor: Current resource is 100% Inferred

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
