Drill holes TM26-193 and TM26-194 returned significant gold intercepts at surface, including grades up to 0.832 g/t Au over 15.0 metres. Reasoning: The announcement reports a new discovery at the Star Target with significant intercepts that extend the known mineralized footprint, supported by robust QA/QC disclosures. - Positive factor: New discovery 500m west of existing pit limit - Positive factor: Significant interval lengths at surface - Positive factor: Grades exceed current MRE cut-off - Positive factor: QA/QC protocols and accredited labs disclosed - Negative factor: True width not disclosed for intercepts Facts used in scoring: 9 ## 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 includes detailed QA/QC protocols, including accredited labs \(Activation and AGAT\) and use of standards/blanks/duplicates. Evidence · text > Activation Laboratories Ltd., Thunder Bay, Ontario, ISO/IEC 17025:2017 is the primary independent analytical service provider. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The Star Target is described as a new discovery 500 metres west of the current optimized pit limit. Evidence · text > New discovery 500 metres west of the current optimized pit constraining the Company's current MRE. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: True width is not disclosed for the reported drill intercepts. Evidence · table > unknown Context: 73.50 ## Extracted facts Stored fact records: 9.
