The Inferred resource has expanded to 181.4 Mt at 0.36% CuEq, now incorporating platinum, palladium, and gold for the first time. Reasoning: The update expands the Inferred resource tonnage by 23% and introduces new precious metal components \(Pt, Pd, Au\) for the first time, significantly increasing the metal content and complexity of the estimate. - Positive factor: Significant tonnage growth in Inferred category - Positive factor: Inclusion of PGEs and gold enhances metal diversity and value - Positive factor: Large-scale porphyry system with critical mineral potential - Positive factor: Open to expansion at depth and along strike - Negative factor: Resource is entirely Inferred category - Negative factor: Significant portion of resource based on historic drill holes Facts used in scoring: 6 ## Classification and evidence **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The entire 181.4 Mt resource is described as an Inferred resource. Evidence · text > expands the Inferred resource tonnage **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The technical report was prepared in accordance with NI 43-101 standards. Evidence · text > prepared in accordance with National Instrument 43-101 Standards **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.

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.
