Hole S-076 successfully penetrated a major fault zone and intersected strong visual copper mineralization at approximately 525 metres depth, targeting a known high-grade horizon. Reasoning: The company successfully reached a targeted deep horizon with strong visual mineralization, though actual grades are not yet confirmed by assays. - Positive factor: successful penetration of principal fault system - Positive factor: strong visual copper mineralization at depth - Positive factor: testing continuation of known high-grade horizon - Negative factor: assay results pending - Negative factor: visual estimates cannot be relied upon Facts used in scoring: 5 ## 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: The release mentions a Qualified Person \(Jeremy Hanson, P. Geo.\) has reviewed and approved the technical aspects. Evidence · text > Qualified Person Jeremy Hanson, P. Geo., a Qualified Person as that term is defined under NI 43-101, is an independent contractor of the Company and has reviewed and approved the technical aspects of this news release. **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The program is described as resource-definition drilling to fill gaps within known mineralization. Evidence · text > western extension of resource-definition drilling ## Extracted facts Stored fact records: 5.

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.
