Operations

Ore is treated using a two-stage crushing process, followed by a two-stage grinding circuit that consists of a semi-autogenous grinding mill and a ball mill. Most of the ground ore is fed to a gravity circuit that recovers about two-thirds of the gold, which is then smelted on site to form dor bars.
