The results include high-grade silver-equivalent intercepts that extend the known mineralisation at depth within the Discovery zone. Reasoning: Infill drilling at the Discovery zone has extended mineralisation at depth with high-grade silver-equivalent intercepts, though specific QA/QC protocols are not detailed in this release. - Positive factor: Step-Out Extension - Positive factor: High-grade intercepts - Negative factor: No QA/QC Disclosure Facts used in scoring: 4 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Results extend the mineralisation at depth beyond the previously defined exploration target. Evidence · text > extend the mineralisation at depth with the majority of holes ending in mineralisation **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: The release does not mention specific QA/QC protocols, lab certification, or QP sign-off. Evidence · text > Additional laboratory results are expected over the coming weeks **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The announcement explicitly describes the program as Phase 4 infill drilling. Evidence · text > Phase 4 infill drilling ## Extracted facts Stored fact records: 4.

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.
