This result represents the widest continuous mineralization encountered at the discovery to date and extends the zone footprint by 50m to the south. Reasoning: The drill hole MC25-232 delivered the widest continuous gold mineralization to date at Argus North, significantly expanding the discovery footprint and confirming structural controls. - Positive factor: Significant width expansion \(208m\) - Positive factor: Step-out drilling confirmed structural corridor - Positive factor: High-grade sub-intervals \(up to 15.2 g/t Au\) - Positive factor: Discovery footprint extended 50m south Facts used in scoring: 7 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The 208m intercept extends the southern footprint of the Argus North zone by 50 metres. Evidence · text > extending the southern footprint of the zone by an additional 50 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: Release details specific QA/QC protocols, including use of blanks, standards, and certified labs \(MSA and ALS\). 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: The 1.0m interval at 11.0 g/t Au and 1.0m at 15.2 g/t Au are exceptionally high grade for this context. Evidence · table > 15.2 Context: 1.0 ## Extracted facts Stored fact records: 7.

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.
