The project features an ~13-year mine life with an average annual production of approximately 92,786 oz of gold and an AISC of US$1,568/oz. Reasoning: The announcement of a positive PEA with robust economics and a high-confidence resource base \(97% Indicated\) is a significant development for a junior explorer. - Positive factor: Strong base case economics \(43% IRR, US$498M NPV\) - Positive factor: High sensitivity to gold price \(85% IRR at spot\) - Positive factor: High proportion of Indicated resource \(97% of mill feed\) - Positive factor: Free-milling mineralization noted - Negative factor: PEA level accuracy \(±30%\) - Negative factor: Inclusion of Inferred resources in the economic model - Negative factor: Project is in Mali \(Tier-3 jurisdiction\) Facts used in scoring: 3 ## Classification and evidence **PEA Only** Polarity: neutral Definition: Only Class 4 / Initial Assessment economics available. Not bankable. Why it applies: The announcement is for a Preliminary Economic Assessment \(PEA\). Evidence · text > Preliminary Economic Assessment \(the "PEA" or "Study"\) **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The project contains a significant Indicated resource component. Evidence · text > 1.283 Moz Au indicated resource **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The project includes an Inferred resource component. Evidence · text > 0.09 Moz Au inferred resource **Free Milling** Polarity: positive Story-specific tag Definition: Simple, clean ore amenable to standard processing without oxidation. Why it applies: Metallurgical test work indicates predominantly free-milling mineralization. Evidence · text > mineralization is predominantly free-milling **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: Mark Kenwright, FAusIMM CP\(Geo\) is named as the Qualified Person. Evidence · text > approved by Mr. Mark Kenwright, FAusIMM CP\(Geo\) **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The source explicitly discloses a revised resource estimate Evidence · text > updated mineral resource estimate ## 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.
