## Minestarters Atlas summary

Capstone Copper has completed the acquisition of the San Pietro copper concessions in Chile's Atacama Region, consolidating its position in the Mantoverde-Santo Domingo copper district. The acquisition adds 16,000 hectares of prospective ground and an Inferred Mineral Resource of 492 million tonnes grading 0.23% copper and 0.05 g/t gold. This strategic move aims to leverage existing infrastructure, unlock exploration upside, and support future integrated district development.

Reasoning: Capstone Copper has completed a strategic acquisition of the San Pietro copper concessions, significantly expanding its land position in the Atacama region of Chile, adding a substantial Inferred Mineral Resource, and consolidating a key copper district.

- Positive factor: District consolidation

- Positive factor: Increased land position

- Positive factor: Immediate mineral inventory addition

- Positive factor: Significant exploration upside

- Positive factor: Strategic fit with existing operations

- Positive factor: Leverages existing and planned infrastructure

- Negative factor: Acquired resource is entirely Inferred

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 43

## Classification and evidence

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: The San Pietro project's resource is reported as an 'Inferred Mineral Resource of 492 million tonnes'.

Evidence · text

> Inferred Mineral Resource of 492 million tonnes

**All Inferred**

Polarity: negative

Definition: 100% of resource is Inferred category — very early stage, no engineering confidence.

Why it applies: The entire resource for the Rincones and Colla deposits at San Pietro is classified as Inferred, with no Measured or Indicated categories reported.

Evidence · text

> Inferred Mineral Resource of 492 million tonnes

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The San Pietro resource is explicitly stated as an 'NI 43-101 compliant Inferred Mineral Resource'.

Evidence · text

> NI 43-101 compliant Inferred Mineral Resource

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: The Mineral Resource was completed by 'independent qualified persons \(Dr. Bruce David, PhD, FAusIMM and Susan Lomas, P.Geo\)'.

Evidence · text

> independent qualified persons \(Dr. Bruce David, PhD, FAusIMM and Susan Lomas, P.Geo\)

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The resource is reported 'using a cut-off grade of 0.3%'.

Evidence · text

> using a cut-off grade of 0.3%

## 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.
