Additionally, the company is conducting magneto-telluric \(MT\) geophysical surveying at the Jiguata porphyry copper project to better define alteration systems. Reasoning: The update signals active field progression through both new drilling and advanced geophysical surveying at two distinct projects. - Positive factor: Commencement of drilling at a new target \(Chirsposo Sur\) - Positive factor: Ongoing geophysical surveying \(MT\) at Jiguata to de-risk porphyry targets - Positive factor: Historical high-grade intercepts at Gaby and Chirsposo support district potential - Negative factor: Most targets are currently in early exploration/untested stages Facts used in scoring: 6 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling is commencing at the previously untested Chirsposo Sur target. Evidence · text > Drilling is commencing at its La Higuera IOCG Project... at the previously untested Chirsposo Sur target **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

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.
