Subject category Comment text
Deposit GOLD IS ALL FREE MILLING; IT OCCURS AS COARSE, WHICH IS RECOVERED BY GRAVITY AMALGAMATION AND FINE WHICH IS PROCESSED THROUGH CIL CYANIDATION. EACH TYPE IS SMELTED SEPARATELY TO BULLION. THE BULLION IS ASSUMED TO BE SHIPPED BY AIR TO THE PERTH MINT. THE SHIPPING COST IS INSIGNIFICANT COMPARED TO THE VALUE OF THE BULLION.
