Tertiary reports seven more Mushima North holes, with mineralisation extending deeper

Tertiary Minerals released further Phase 4 drilling results from Mushima North, Zambia, on 7 September 2026.

Selected intersections

All seven newly reported holes intersected near-surface mineralisation, and most ended in mineralisation. The quoted intervals are downhole lengths; true widths are unknown.

Interpretation

The results support further investigation of depth continuity and higher-grade zones. They do not establish a new mineral resource or demonstrate processing recoveries.

The previously stated 15–30 million tonnes at 40–60g/t silver equivalent remains an exploration target, with the associated uncertainty. Equivalent grades also depend on metal-price and recovery assumptions.

Further laboratory results are expected in coming weeks. Those results and geological modelling will determine whether the target can advance toward a supported resource estimate.
