## Minestarters Atlas summary

Andina Copper has reported drill results from the Piuquenes East project, including a 208 m intercept at 0.31% Cu. Additionally, a new Magnetotelluric \(MT\) survey has identified a large, deep-seated anomaly at Piuquenes North, which the company plans to test with upcoming drilling.

Reasoning: The release reports significant drill intercepts at Piuquenes East and defines a large, high-priority MT anomaly at Piuquenes North, suggesting potential for system expansion.

- Positive factor: expansion of known porphyry mineralization

- Positive factor: new high-priority geophysical target defined

- Positive factor: visual confirmation of mineralization persistence

- Negative factor: assays for PIU09 are pending

Facts used in scoring: 6

## 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 includes a Qualified Person \(QP\) sign-off by Francisco Montes.

Evidence · text

> Francisco Montes, a consultant of Andina Copper Corp and a “qualified person” \(“QP”\)

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling at Piuquenes East is described as expanding known porphyry mineralization.

Evidence · text

> Ongoing drilling at Piuquenes East continues to expand known porphyry copper-gold mineralization

## 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.
