The results delineate a substantial high-grade zone at Target A1 that remains open at depth and along strike. Reasoning: High-grade silver-copper-zinc intercepts reported at Target A1, extending the known mineralised footprint. - Positive factor: high-grade silver intercepts - Positive factor: continuation beyond target boundary - Positive factor: Discovery Zone remains open at depth and strike - Negative factor: true widths unknown - Negative factor: assays for 8 holes still pending Facts used in scoring: 10 ## Classification and evidence **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The document explicitly states that true widths for the reported intervals remain unknown. Evidence · text > true widths for these intervals remain unknown **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 disclose QA/QC procedures, lab certification, or QP sign-off. Evidence · text > Results have been released for 29 of the 39 RC drill-holes ## Extracted facts Stored fact records: 10.

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.
