The updated MRE reports 5.7 Mt of Measured and Indicated resources at 79 g/t Ag and 0.42 g/t Au, though total contained metal has decreased compared to the 2017 estimate due to improved modeling rigor. Reasoning: The update provides a more robust and transparent resource using contemporary modeling, though it results in a reduction of contained metal compared to the 2017 estimate due to more rigorous methodology. - Positive factor: NI 43-101 compliant - Positive factor: QP signed - Positive factor: QA/QC disclosed - Positive factor: underground mining parameters applied - Negative factor: reduction in reported contained ounces compared to 2017 MRE - Negative factor: significant portion in Inferred category Facts used in scoring: 12 ## 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: Technical report prepared in accordance with NI 43-101 standards. Evidence · text > prepared in accordance with National Instrument 43-101 **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: Mr. Simon Mortimer \(FAIG \#7795\) of Atticus Geoscience Consulting Ltd. is named as the independent Qualified Person. Evidence · text > prepared by independent Qualified Person, Mr. Simon Mortimer **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions QA/QC checks using blanks, core duplicates, and certified reference material.

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.
