The 2026 PEA reports a significantly improved economic profile with a base case NPV \(5%\) of $3.5B and an IRR of 93%, supported by an extended 14-year mine life. Reasoning: The updated PEA shows substantial economic improvements in NPV, IRR, and mine life compared to the previous study, driven by higher price assumptions and improved payability. - Positive factor: Significant NPV improvement \(doubled from prior PEA\) - Positive factor: Strong IRR of 93% in base case - Positive factor: Extended mine life from 11 to 14 years - Positive factor: Increased metal payability for gold and silver - Positive factor: Strong capital efficiency ratio \(7.6x\) - Negative factor: Project is in preliminary stage \(PEA\) - Negative factor: Includes significant Inferred resource component Facts used in scoring: 2 ## Classification and evidence **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 **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document presents an updated Mineral Resource Estimate \(2026 MRE\).

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.
