The estimate includes 1.14 Mt at 5.46 g/t gold in the Indicated category and 0.19 Mt at 2.99 g/t gold in the Inferred category, based on a 0.92 g/t Au cut-off. Reasoning: The announcement of a maiden MRE with a strong Indicated grade and high-density drilling provides significant de-risking for the Pepas deposit. - Positive factor: Maiden Mineral Resource Estimate established - Positive factor: High Indicated grade of 5.46 g/t Au - Positive factor: Close-spaced drilling \(15-30m\) supports classification - Positive factor: NI 43-101 compliant with QP sign-off Facts used in scoring: 2 ## Classification and evidence **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable. Why it applies: First formal MRE for the Pepas deposit. Evidence · text > completion of a maiden Mineral Resource estimate \("MRE"\) for the Pepas deposit **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: Significant portion of the resource is in the Indicated category. Evidence · text > 1.14 Mt at 5.46 g/t Au in Indicated classification **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The MRE was prepared in accordance with NI 43-101 standards. Evidence · text > disclosed to National Instrument 43-101 \("NI 43-101"\) **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. Galen White, a Qualified Person, supervised the estimate. Evidence · text > prepared under the supervision of Mr. Galen White... Mr. White is a Qualified Person \("QP"\) **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 reporting cut-off grade of 0.92 g/t Au is clearly stated. Evidence · text > reporting cut-off grade of 0.92g/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.
