## Minestarters Atlas summary

Andina Copper has completed two drill holes \(PIU12 and PIU13\) at the Piuquenes North target, confirming a multiphase porphyry copper system. The drilling successfully intersected the targeted Magnetotelluric \(MT\) geophysical anomaly, with visible chalcopyrite and bornite mineralization observed. Assay results are currently pending.

Reasoning: The announcement confirms the discovery of a new porphyry copper system at a previously untested target, successfully validating a geophysical anomaly, though actual grades are not yet available.

- Positive factor: Confirmation of porphyry system at new target

- Positive factor: Successful testing of MT geophysical anomaly

- Positive factor: Presence of chalcopyrite and bornite observed visually

- Negative factor: Assay results are pending

- Negative factor: No numeric grades reported

- Negative factor: Visual logging only

Facts used in scoring: 2

## 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: The release details a QA/QC program including certified reference materials, 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: Not applicable as QA/QC is disclosed, but the lack of assay results is a notable limitation.

Evidence · text

> Assay results for both PIU12 and PIU13 are pending.

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
