The inaugural program also identified a new parallel shear zone and significant antimony mineralization, suggesting strong critical-metal potential. Reasoning: Inaugural drilling program at the 1350 Zone has returned exceptional silver-equivalent grades and discovered a new parallel structure, significantly expanding the exploration potential of the Greyhound Property. - Positive factor: exceptional silver grades - Positive factor: discovery of new parallel shear zone - Positive factor: critical mineral \(antimony\) presence - Positive factor: QA/QC disclosed - Negative factor: poor drill recoveries at Bulldog target - Negative factor: true widths not yet determined Facts used in scoring: 10 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 4,859 g/t AgEq is exceptionally high grade. Evidence · text > standout high-grade intercept in GH25-05 returned 4,859 g/t AgEq\* over 0.15 m **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Discovery of a previously unknown shear zone parallel to the main shear. Evidence · text > uncovered a previously unknown mineralized structure parallel to the main Greyhound shear **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 ALS Labs \(ISO 17025 accredited\), use of blanks, duplicates, and standards. Evidence · text > ALS Labs \(an independent ISO-IEC 17025:2017 and ISO 9001:2015 accredited geo-analytical laboratory \) **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: Not applicable as QA/QC is disclosed. ## Extracted facts Stored fact records: 10.
