Update yesterday from AVZ's () (OTCMKTS:AZZVF) (FRA:3A2) Nigel Ferguson tells Proactive's Andrew Scott they've received further high-grade lithium and tin mineralisation from its mineral resource drilling at the Manono lithium and tin project in the Democratic Republic of Congo. It drilled 203.3 metres at 1.59% lithium and 1,014 ppm tin from pit floor ‘wedge’ at Roche Dure. The assay results come from the first four of nine planned diamond drill holes at Roche Dure in previously undrilled areas beneath the historical pit, which were inaccessible and underwater during the earlier resource drilling programs.
