The updated MRE now totals 742,000 Indicated ounces and 69,000 Inferred ounces of gold. The PEA highlights compelling economics, including a post-tax NPV\(5%\) of US$104 million and an IRR of 49% at consensus gold prices, with an average annual gold production of 30,000 ounces over a 4-year mine life. Reasoning: CopAur Minerals announced a substantial 52% increase in its gold resource estimate and positive preliminary economic assessment results for the Kinsley Mountain Gold Project, indicating strong potential for project advancement and value creation. - Positive factor: Significant 52% growth in total contained gold ounces in the Mineral Resource Estimate \(MRE\) - Positive factor: Positive Preliminary Economic Assessment \(PEA\) results with strong post-tax NPV and IRR at consensus gold prices - Positive factor: High-grade Secret Canyon zone contributes significantly to the Indicated resource - Positive factor: NI 43-101 compliant MRE and PEA, signed off by Qualified Persons - Positive factor: Project located in a favorable jurisdiction \(Nevada\) - Negative factor: PEA is preliminary in nature and based on mineral resources, not reserves, carrying inherent uncertainty - Negative factor: Significant portion of the resource is in the Inferred category, which has lower confidence - Negative factor: Some cutoff grades are variable or not explicitly stated for combined categories, potentially affecting comparability Facts used in scoring: 16 ## Classification and evidence **Tonnage Growth** Polarity: positive Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved.

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.
