Analysis by Minestarters Atlas
Minestarters Atlas analysis
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 factors
- extension of mineralisation at depth
- high-grade silver equivalent intercepts
- extension beyond existing Exploration Target
Negative factors
- full depth and sulphide transition untested
Facts used in scoring: 6

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.
