Combined M&I resources now total 228 koz at 3.98 g/t Au, representing a 42% increase in contained gold compared to the 2021 estimates. Reasoning: The update shows substantial growth in contained gold ounces and high-grade underground continuity, significantly de-risking the project via proximity to existing infrastructure. - Positive factor: Significant contained gold growth in both M&I \(42%\) and Inferred \(28%\) categories - Positive factor: Strategic proximity to existing Bachelor Mill infrastructure \(within 900m\) - Positive factor: High-grade underground resources \(up to 4.45 g/t Au\) - Positive factor: Robust QA/QC disclosure including independent verification by ALS Facts used in scoring: 4 ## Classification and evidence **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured.

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.
