## Minestarters Atlas summary

Tertiary Minerals has reported Phase 4 drilling results from its Mushima North project in Zambia, extending silver-copper-zinc mineralisation beyond the previous Exploration Target depth. The results include several high-grade silver equivalent intercepts, including 22m at 105 g/t AgEq.

Reasoning: New drilling has successfully extended the known mineralisation depth and returned several high-grade silver equivalent intercepts.

- Positive factor: extension of mineralisation at depth

- Positive factor: high-grade silver equivalent intercepts

- Positive factor: extension beyond existing Exploration Target

- Negative factor: full depth and sulphide transition untested

Facts used in scoring: 6

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling has extended mineralisation beyond the depth of the existing 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.
