AVZ Minerals continues to kick goals at its Manono lithium project in Africa with recent drilling to facilitate ground-water monitoring returning wide intercepts of high-grade lithium mineralisation, extending the known ore envelope an additional 90 metres beyond the current pit design. New drill intercepts include a stunning 98.0m grading 1.79 per cent lithium oxide and 1,174 parts per million tin from only 2m down-hole.
