General comments

Subject category Comment text
Deposit CONCENTRATOR IS LOCATED AT EPOCH, THE CONCENTRATES WILL BE DELIVERED TO THE BINDURA SMELTER. THE BINDURA PLANT HAS RECENTLY BEEN EXPANDED TO DEAL WITH CONCENTRATES FROM SHANGANI AND FROM EPOCH, AND IN MID 1976, PRODUCTION OF ELECTROLYTIC NICKEL WAS 2,500 TPY. THIS IS EXPECTED TO HAVE DOUBLED BY 1980. THERE ARE NO PUBLISHED FIGURES AVAILABLE FOR THE INDIVIDUAL MINES OUTPUT.
