The grinding circuit consists of two parallel lines, each having one twin pinion semiautogenous (SAG) mill (36''X20'') and one twin pinion ball mill (26''''). The gravity circuit currently recovers approximately 25% of the gold. The remaining gold in ore is sent to cyanidation followed by carbon in pulp (CIP) gold recovery.
