The reserves support a 15-year mine life with a post-tax NPV of US$254 million at a 5% discount rate. Reasoning: The announcement of the company's first mineral reserves at Moss Mine is a major de-risking milestone with strong economic indicators. - Positive factor: First mineral reserve declaration for the company - Positive factor: Strong project economics with US$254M NPV - Positive factor: High return on invested capital acquisition - Positive factor: No initial capital required - Positive factor: Significant exploration upside mentioned - Negative factor: Low grade \(0.327 g/t Au\) - Negative factor: Ongoing royalty litigation with Royal Gold Inc. 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 reserve estimate was prepared in accordance with NI 43-101. 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: Mohsin Hashmi, P.Eng. is named as the Qualified Person. Evidence · text > prepared by Mohsin Hashmi, P.Eng., a Qualified Person **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 cut-off grade of 0.14 g/t Au is explicitly stated. Evidence · text > Mineral Reserves are reported using a cut-off grade of 0.14 g/t Au ## Extracted facts Stored fact records: 2.

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.
