Results include silver assays up to 1,159 g/t Ag at the new Minas Nuevas zone and significant strike extensions of the Paulina Breccia and Las Guasimas systems. Reasoning: Discovery of high-grade silver-lead-zinc mineralization via LiDAR-guided surface sampling, extending known strike lengths and identifying new zones. - Positive factor: High-grade silver intercepts \(1,159 g/t\) - Positive factor: Discovery of new polymetallic zones \(Minas Nuevas\) - Positive factor: Extension of known mineralization along strike on MF2 - Positive factor: District-scale potential demonstrated by 10km mineralized system - Positive factor: QA/QC disclosed with certified lab and QP sign-off - Negative factor: Sampling is surface-based \(channel/grab\) rather than drill-core - Negative factor: Grab samples are only indicative Facts used in scoring: 34 ## 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 implementation of industry standard practices, including certified reference materials and blanks, with SGS lab accreditation. Evidence · text > The lab is accredited to ISO/IEC 17025:2017. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Silver assay of 1,159 g/t is exceptionally high. Evidence · text > assays up to 1,159 g/t Ag ## Extracted facts Stored fact records: 34.

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.
