The update shows a 37% increase in M&I Mineral Resources to 10.6 Moz gold and a 40% increase in Proved & Probable Ore Reserves to 7.0 Moz gold compared to 2025 levels. Reasoning: Significant increases in both M&I Mineral Resources \(37%\) and Proved & Probable Ore Reserves \(40%\) across the portfolio, driven by project growth and optimization. - Positive factor: Tonnage Growth - Positive factor: Contained Metal Growth - Positive factor: Category Upgrade - Positive factor: QP/CP Signed - Positive factor: JORC Compliant Facts used in scoring: 20 ## Classification and evidence **Tonnage Growth** Polarity: positive Definition: Tonnage increase reaching the strong tier vs prior estimate, with grade maintained or improved. Why it applies: M&I Mineral Resources increased by 37% \(2.9 Moz\) compared to 2025. Evidence · text > reflecting a 2.9 Moz or 37% increase **Contained Metal Growth** Polarity: positive Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes. Why it applies: Proved and Probable Ore Reserves increased by 2.0 Moz \(40%\) compared to 2025. Evidence · text > representing a 2.0 Moz or 40% increase **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: Estimates are reported in accordance with the 2012 JORC Code. Evidence · text > reported in accordance with the 2012 Australasian Code **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: Competent Persons Daniel Saunders and Adrian Ralph are named and provide consent. Evidence · text > based on, and fairly represents, information and supporting documentation prepared by Daniel Saunders, a Competent Person ## Extracted facts Stored fact records: 20.

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.
