The results include new silver-rich veins at Minas Nuevas and strike extensions of the Paulina Breccia and Las Guasimas zones. Reasoning: Discovery of high-grade silver-rich veins and extension of known mineralization along strike at El Potrero, validating LiDAR-based targets. - Positive factor: High-grade silver intercepts \(1,159 g/t\) - Positive factor: Extension of mineralization along strike - Positive factor: District-scale potential demonstrated - Positive factor: Polymetallic nature \(Au-Ag-Pb-Zn\) - Negative factor: Sampling via grab/surface methods \(indicative only\) Facts used in scoring: 8 ## Classification and evidence **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 **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 NI 43-101 standards, certified reference materials, blanks, and SGS lab accreditation. Evidence · text > The technical results contained in this news release have been reported in accordance with National Instrument 43-101 Standards **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Mineralization has been extended along strike on the MF2 block. Evidence · text > continued field work has extended the previously announced silver-lead-zinc \(Ag-Pb-Zn\) mineralization along strike ## 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.
