Verification sampling by an independent P.Geo confirmed high-grade silver intercepts, including 991 g/t Ag over 0.7m, supporting a transition toward underground access. Reasoning: Verification sampling confirms high-grade silver at surface, and the company has formally engaged Peruvian authorities to secure access permits. - Positive factor: High-grade silver surface mineralization confirmed - Positive factor: Permitting process initiated for underground access - Positive factor: QA/QC oversight by P.Geo - Negative factor: No QA/QC samples \(blanks/standards\) inserted in verification sampling - Negative factor: Regulatory timelines for permits are subject to review Facts used in scoring: 8 ## 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: Release mentions samples were bagged, labelled, and sealed, and analyzed by an ISO 9001-certified laboratory. Evidence · text > All samples were bagged, labelled, and sealed in the field using single-use security ties, transported by the author to Lima, Peru, and analyzed by Certimin S.A., an ISO 9001–certified laboratory **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Silver grades of 869 g/t and 991 g/t are exceptionally high for an epithermal system. Evidence · text > 869 g/t silver , with associated lead and zinc, from a 0.5-metre surface vein channel sample 991 g/t silver from a 0.7-metre surface vein channel sample **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 author explicitly states that no additional quality control samples \(blanks, standards, or duplicates\) were inserted. Evidence · text > No additional quality control samples \(blanks, standards, or duplicates\) were inserted due to the limited number of samples collected ## Extracted facts Stored fact records: 8.

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.
