The resource comprises 23.6Mt at 25.8% Mn and 12.5Mt at 54.9% Fe, with over 90% of the manganese resource classified as Measured and Indicated. Reasoning: Landmark maiden resource for a high-grade manganese and iron deposit with exceptional grade and scale. - Positive factor: Maiden resource establishment - Positive factor: High grade manganese and iron - Positive factor: High M&I percentage \(>90%\) - Positive factor: Significant DSO potential Facts used in scoring: 2 ## Classification and evidence **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: The release defines a landmark maiden Mineral Resource Estimate for the Wandanya Deposit. Evidence · text > landmark maiden Mineral Resource Estimate \(MRE\) **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: Over 90% of the manganese resource is in Measured and Indicated categories. Evidence · text > Over 90% of the manganese resource and 100% of the iron resource are in Measured and Indicated categories ## 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.
