The combined leach pad M&I resource now totals 49.25 million ounces of silver equivalent. Reasoning: Significant upgrade of leach pad resources to Measured and Indicated categories, providing high-confidence material for the upcoming Pre-Feasibility Study. - Positive factor: Category Upgrade - Positive factor: Tonnage Growth - Positive factor: QP/CP Signed - Positive factor: NI 43-101 Compliant Facts used in scoring: 6 ## Classification and evidence **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: Upgrade of LP1 from Indicated to Measured/Indicated and LP2 from Inferred to Indicated. Evidence · text > resulting in an upgrade of previously Indicated resources on LP1 to the Measured and Indicated \("M&I"\), and Inferred to Indicated on LP2. **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource estimate is part of a technical report prepared by a Qualified Person in compliance with NI 43-101. Evidence · text > A copy of the National Instrument 43-101 \("NI 43-101"\) technical report \(the "Report"\) on the Project will be filed on the SEDAR+ shortly **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.
