Drillhole CDH013 intersected 322m at 0.51% Cu, extending the mineralized footprint to the northwest. Reasoning: Significant step-out drilling at Cobrasco porphyry intersected high-grade copper \(0.65% Cu over 200m\) and expanded the known footprint. - Positive factor: Step-out drilling successfully extended the mineralized footprint to the northwest - Positive factor: High-grade copper intercepts \(up to 2.2% Cu in 2m samples\) in a porphyry system - Positive factor: Significant width of mineralization \(322m\) at economic grades - Positive factor: QA/QC protocols and independent laboratory \(ALS\) clearly disclosed - Negative factor: Apparent widths reported without true width disclosure Facts used in scoring: 7 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: CDH013 was collared on a new pad 350m northwest of Pad 3, expanding the footprint. Evidence · text > significant step-out drilling at its Cobrasco porphyry copper-molybdenum discovery **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 systematic insertion of standards, blanks, and duplicates, and names ALS as the laboratory. Evidence · text > The Company’s QA/QC program includes the systematic insertion of certified reference materials, coarse and fine blanks, coarse-reject duplicates and pulp duplicates **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: The document explicitly states that reported interval widths are downhole lengths and may not represent true widths. Evidence · text > Reported interval widths are downhole lengths and may not represent the true widths of mineralization. ## 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.
