The project hosts a significant gold and silver resource, with an Indicated gold resource of 1.44 Moz at 9.47 g/t Au and an Inferred resource of 0.52 Moz at 8.85 g/t Au. Reasoning: The document provides an updated project summary including a high-grade gold and silver resource estimate \(MRE\) and validates development progress with new LiDAR survey data. - Positive factor: High-grade gold resource - Positive factor: Strong M&I ratio - Positive factor: Strategic infrastructure proximity - Positive factor: Advanced engineering support via LiDAR - Negative factor: Underground mining complexity - Negative factor: Reliance on third-party processing Facts used in scoring: 4 ## 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 resource estimate is explicitly stated as an updated NI 43-101 MRE. Evidence · text > The Company's updated NI43-101 Mineral Resource Estimate \(MRE\) **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: Kyle Mehalek, P.E., is named as the QP who reviewed and approved the technical disclosure. Evidence · text > Kyle Mehalek, P.E.., is the QP within the meaning of NI 43-101 and has reviewed and approved the technical disclosure ## Extracted facts Stored fact records: 4.

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.
