General comments

Subject category Comment text
Deposit BENEFICIATION CONSISTS OF FLOTATION OF THE MOUNT CHARLOTTE AND FIMISTON ORES IN SEPARATE MILLS. THE CONCENTRATES ARE MIXED BEFORE ROASTING, AND THEN TREATED BY CYANIDATION AND ZINC DUST PRECIPITATION BEFORE MELTING TO BULLION. THE BULLION IS ASSUMED TO BE SHIPPED BY AIR TO THE PERTH MINT; SHIPPING COSTS ARE INSIGNIFICANT COMPARED TO THE VALUE OF THE BULLION.
