The first tranche payment for Aim-listed Bushveld Minerals’ $17.2-million acquisition of Evraz Group’s Vametco vanadium mine operation, in the North West, has been delayed until July 22 to allow the parties to wrap up amendments to the purchase agreement. Bushveld and financing partner Yellow Dragon, which, together, established the 45:55 special purpose vehicle Bushveld Vametco to acquire the assets, are also finalising working capital and net debt adjustments.
