## Minestarters Atlas summary

Tertiary Minerals PLC has identified a 400-metre-long higher-grade silver-copper-zinc zone at its Mushima North project in Zambia. The drilling results indicate that the mineralisation extends beyond the current Exploration Target and remains open at depth.

Reasoning: The announcement reports a significant new higher-grade silver-copper-zinc zone at the Mushima North project that extends beyond previous targets.

- Positive factor: higher-grade zone identified

- Positive factor: mineralisation extends beyond Exploration Target

- Positive factor: remains open at depth

Facts used in scoring: 3

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling shows mineralisation extending beyond the current Exploration Target.

## 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.
