The holes intersected a multiphase porphyry copper system, confirming the presence of copper sulphides within a previously untested geophysical anomaly. Assay results are currently pending. Reasoning: The release confirms the presence of a multiphase porphyry copper system at a new target \(Piuquenes North\) based on visual logging, but lacks assay data to confirm grade. - Positive factor: Confirmation of porphyry system at previously untested target - Positive factor: Successful testing of MT geophysical anomaly - Positive factor: Presence of visible chalcopyrite and bornite - Negative factor: Assay results are pending - Negative factor: No numeric grades reported Facts used in scoring: 4 ## 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 details QA/QC program including standards, blanks, and duplicates. Evidence · text > The Company implemented a quality assurance and quality control \(QA/QC\) program that included the insertion of certified reference materials, blanks, and duplicates **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: While procedures are mentioned, actual assay results are pending, so the effectiveness of the QA/QC for these specific intercepts cannot be verified. Evidence · text > Assay results for both PIU12 and PIU13 are pending. ## Extracted facts Stored fact records: 4.

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.
