Drilling intersected high-grade gold, including 19.7 g/t Au and 13.7 g/t Au, with visible gold observed in several intervals. Reasoning: Significant new discovery \(Argus West\) with high-grade intercepts and visible gold, demonstrating structural control and expansion potential near a known discovery. - Positive factor: Discovery of new gold zone \(Argus West\) 250m from Argus North - Positive factor: High-grade intercepts including 19.7 g/t Au and 13.7 g/t Au - Positive factor: Visible gold observed in multiple holes - Positive factor: Step-out drilling successfully extending mineralization strike and depth - Positive factor: Discovery occurs in both volcanic and sedimentary host rocks Facts used in scoring: 9 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drill holes MC25-213 and MC25-199 are described as step-out holes 250m and 430m from Argus North. Evidence · text > Results reported today from Argus West include two step-out drill holes, MC25-213 and MC25-199 **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 details specific QA/QC protocols, including blanks, standards, duplicates, and certified lab accreditation \(ISO 17025\). Evidence · text > The Company maintains a robust QA/QC program that includes the collection and analysis of duplicate samples and the insertion of blanks and standards **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 19.7 g/t Au intercept is exceptionally high for an orogenic gold system. Evidence · table > 19.7 Context: 1.0 **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The new Argus West zone is located 250m from the existing Argus North discovery. Evidence · text > discovery of a new zone of near-surface gold mineralization, 250 meters \(" m "\) southwest of the Argus North Zone ## Extracted facts Stored fact records: 9.

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.
