## Minestarters Atlas summary

Andina Copper has confirmed a new porphyry copper-gold discovery at Piuquenes North, Argentina, with drillhole PIU13 returning 468m at 0.50% Cu and 0.30 g/t Au. The mineralization is hosted within a large, largely untested geophysical anomaly, suggesting significant expansion potential.

Reasoning: The drill results confirm a new porphyry discovery with substantial width and strong copper grades, testing a large geophysical target.

- Positive factor: discovery of new porphyry copper-gold system

- Positive factor: significant width and grade \(468m @ 0.50% Cu\)

- Positive factor: large untested geophysical anomaly

- Positive factor: proximity to known high-grade projects

- Negative factor: only a small portion of the MT anomaly tested

Facts used in scoring: 12

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Discovery of a new porphyry system at the previously undrilled Piuquenes North target.

Evidence · text

> confirms the discovery of a new porphyry copper-gold system at Piuquenes North

**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 protocols including certified labs \(ALS\), blanks, standards, 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

## 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.
