The update also significantly expands the Inferred resource to 805.1 Mt at 0.34% NiTEq, containing substantial amounts of nickel, copper, cobalt, and platinum group metals. Reasoning: The update establishes a maiden Indicated resource and significantly expands the Inferred resource, representing a major step in project de-risking and scale. - Positive factor: Establishment of maiden Indicated resource - Positive factor: Substantial tonnage growth in Inferred category - Positive factor: Significant contained metal increase - Positive factor: Large-scale polymetallic system - Positive factor: Strategic location adjacent to operating mines Facts used in scoring: 14 ## Classification and evidence **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The company has established its first Indicated Mineral Resource of 29.4 Mt. Evidence · text > establishes our first Indicated Mineral Resource **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: The update includes the first definition of an Indicated Mineral Resource. Evidence · text > First definition of an Indicated Mineral Resource **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: The Inferred resource has been significantly expanded. Evidence · text > More Than Doubles Stillwater West Inferred Mineral Resource **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: Timothy O. Kuhl and Dr. Ted Eggleston are named as independent Qualified Persons. Evidence · text > The Qualified Person for the estimate is Mr. Timothy O. Kuhl, RM SME **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The estimate was prepared in accordance with NI 43-101 standards. Evidence · text > in accordance with National Instrument 43-101 **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: The NiTEq base case cut-off grade of 0.20% is clearly stated. Evidence · text > using a 0.20% NiTEq cut-off grade ## Extracted facts Stored fact records: 14.

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.
