## Minestarters Atlas summary

Puma Exploration has announced high-grade copper and silver results from its 2025 field exploration program at the Legacy Project in New Brunswick. The results confirm multiple occurrences of copper, silver, and gold located outside and adjacent to the historical Legacy Deposit.

Reasoning: The announcement reports high-grade copper \(12%\) and silver \(152 g/t\) occurrences that extend the mineralized footprint outside the historical deposit area.

- Positive factor: high-grade copper intercepts

- Positive factor: high-grade silver intercepts

- Positive factor: extension outside historical deposit

Facts used in scoring: 2

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The results confirm occurrences outside and adjacent to the historical Legacy Deposit area.

## 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.
