The study demonstrated that XRT sorting can effectively identify and reject zero-grade mafic and intermediate volcanic material, which constitutes 20-25% of the current resource envelope. Reasoning: The ore sorting study successfully demonstrated the ability to reject zero-grade material using XRT, which could significantly improve future project economics by reducing waste processing. - Positive factor: effective waste rejection - Positive factor: potential for improved economics - Positive factor: preliminary validation of SBS - Negative factor: visual estimation only - Negative factor: small sample size Facts used in scoring: 3 ## Classification and evidence **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: The sorting study was conducted on a small sample size \(76kg\) using visual estimation. Evidence · text > Due to the small size of the sample, the results of the dynamic testing are predicated on visual estimation **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The document reports an inferred resource component. Evidence · text > Inferred resources totalling 2,215,000 tonnes **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The document reports an indicated resource component. Evidence · text > Indicated gold resource totalling 16,190,000 tonnes ## Extracted facts Stored fact records: 3.

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.
