Drillhole PIU13 intersected a 468m wide porphyry system grading 0.50% Cu and 0.30 g/t Au, including a high-grade 164m interval at 0.70% Cu. Reasoning: Initial discovery drilling at Piuquenes North confirmed a large, high-grade porphyry copper-gold system within a significant geophysical anomaly. - Positive factor: discovery of new porphyry copper-gold system - Positive factor: large continuous intercept \(468m\) - Positive factor: high-grade core \(164m at 0.70% Cu\) - Positive factor: geophysical anomaly confirmed by drilling - Positive factor: proximate to known high-grade projects - Negative factor: only a small part of the MT anomaly tested - Negative factor: intervals are downhole/uncorrected Facts used in scoring: 12 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling at Piuquenes North is described as initial discovery drilling at a newly generated and previously undrilled target. Evidence · text > initial discovery drilling at Piuquenes North **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).
