The drilling also successfully extended the Tenorita mineralized trend by 200 metres to a total length of 1.9 kilometres. Reasoning: Exceptional copper grades reported \(21.84% Cu\) and significant strike extension of the Tenorita trend, supported by QA/QC disclosure. - Positive factor: Bonanza intercept of 21.84% Cu - Positive factor: Step-out extension of Tenorita trend by 200m - Positive factor: QA/QC disclosed with ALS-Patagonia lab - Positive factor: High-grade infill results - Negative factor: Drilling stopped due to artisanal mining void Facts used in scoring: 14 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 21.84% Cu is an exceptionally high-grade zone. Evidence · text > 1 metre graded 21.84% copper, the highest sample recorded from drilling at Buen Retiro to date **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The Tenorita trend was extended by 200 metres. Evidence · text > Reverse-circulation drilling extended the main mineralized trend within Tenorita by 200 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 mentions ALS-Patagonia lab and 12% QA/QC sample insertion. Evidence · text > Samples are prepared and analyzed at the ALS-Patagonia laboratory in Copiapó, and quality assurance and quality control samples inserted by the company make up about 12% of primary core samples. ## Extracted facts Stored fact records: 14.
