Recent results include a new shallow mineralization zone at Pepas West and the first porphyry intersection at El Cedro. Reasoning: The company is successfully advancing multiple prospects \(Pepas, APTA, El Cedro\) with new drill intersections, though some recent results are low-grade. - Positive factor: New mineralization zone identified at Pepas West - Positive factor: Immediate porphyry intersection at El Cedro - Positive factor: Multiple drilling rigs active across three prospects - Negative factor: Low-grade intercepts at APTA \(MAP108\) - Negative factor: Pepas West geometry may require high-density shallow drilling Facts used in scoring: 5 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The document does not explicitly detail QA/QC protocols like blanks or standards, though it mentions drilling and assays. Evidence · text > Gold intersections are reported using a lower cut-off of 0.3 g/t Au over 3 metres. **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 lacks specific mention of laboratory certification, QP sign-off, or specific QA/QC methods used. Evidence · text > Gold intersections are reported using a lower cut-off of 0.3 g/t Au over 3 metres. ## Extracted facts Stored fact records: 5.

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.
