Gold metallurgy was excellent. Greater than 9007o of the gold will report to a gravity concentrate. Flotation will recover a further SYo of the gold with the bulk of the copper into a salable copper concentrate. The grind fineness appears to have little effect on the metallurgical performance of the ore.
