Notable intercepts include up to 58.2 g/t Au and 631 g/t Ag, demonstrating continuity along the Dos de Mayo vein. Reasoning: The release reports high-grade gold and silver intercepts that extend previously known mineralization, supported by robust QA/QC disclosures. - Positive factor: High-grade intercepts - Positive factor: Strike continuity confirmed - Positive factor: QA/QC disclosed - Positive factor: Epithermal deposit type - Negative factor: Assays pending for several holes Facts used in scoring: 6 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 58.2 g/t Au and 631 g/t Ag are exceptionally high grades for an epithermal system. Evidence · text > returned 58.2 g/t Au and 631 g/t Ag over 0.41 metres **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 release details specific QA/QC procedures, including certified reference materials, blanks, and SGS laboratory accreditation. Evidence · text > including inserting certified reference material samples and blank samples into sample batches **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling confirmed and extended the previously announced mineralization. Evidence · text > confirmed and extended the previously announced high-grade gold-silver mineralization ## Extracted facts Stored fact records: 6.

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.
