Summary
Tertiary Minerals plans to conduct up to 1,000 metres of diamond drilling at its Mushima North project in Zambia to test for a deeper, higher-grade sulphide deposit. The campaign follows recent high-grade silver-equivalent intercepts and aims to expand on the existing exploration target. Drilling is expected to begin after a shareholder meeting on 28 October, pending approval of a recent £1 million placement.
Reasoning: The company is announcing a new drilling campaign to test depth extensions of a known discovery, following a recent capital raise.
Positive factors
- Planned deeper drilling to test for higher-grade sulphide system
- Recent high-grade silver equivalent intercepts reported
- Upcoming maiden mineral resource estimate expected by end of 2026
Negative factors
- Drilling commencement is subject to shareholder approval of recent placement
Facts used in scoring: 2
Classification and evidence
Infill Drillingneutral

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.
