The acquisition, valued at A$714,000 \(illustrative\), significantly increases total resources by 126.5% and Indicated Resources by 486.6%, with resource growth materially outpacing equity dilution. The company now shifts focus to unlocking value through resource growth, development studies, and strategic opportunities for its expanded portfolio. Reasoning: Yari Resources has completed the acquisition of the Arcadia Coal Project, significantly expanding its Queensland coal resource portfolio to over 500Mt, with resource growth materially outpacing equity dilution. - Positive factor: Acquisition of Arcadia Coal Project completed - Positive factor: Significant increase in total coal resources \(126.5%\) - Positive factor: Substantial growth in Indicated Resources \(486.6%\) - Positive factor: Resource growth materially outpaced equity dilution - Positive factor: Strategic consolidation in the Bowen Basin Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 29 ## Classification and evidence **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The document explicitly states that the coal resources are reported under JORC Code \(2012\). Evidence · text > Yari’s reported JORC Coal Resources to 504.9Mt **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: Mr Mark Biggs is named as a Competent Person who has approved the statement as a whole, and the original Arcadia resource was prepared by JB Mining Services Pty Ltd. Evidence · text > Mr Biggs has approved the Statement as a whole and consents to its inclusion in this report in the form and context in which it appears. **Tonnage Growth** Polarity: positive Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved. Why it applies: Total resources increased by 126.5% and Indicated Resources increased by 486.6% due to the acquisition. Evidence · text > total resources increase 126.5% and Indicated Resources increase 486.6% **Category Upgrade** Polarity: positive Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal. Why it applies: Indicated Resources increased by 486.6%, significantly improving the confidence level of the overall resource portfolio. Evidence · text > Indicated Resources increase 486.6% **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document announces an expanded resource base for the company following an acquisition, combining existing estimates. Evidence · text > Expanded resource base and growth assessment **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: A significant portion of the combined resource, 307.2Mt, is classified as Inferred, which is a speculative category.

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.
