Ore is mined principally by longitudinal AVOCA and modified AVOCA stoping, with transverse stoping used in the wider PQ Deeps zone. Processing comprises underground and surface crushing, rod and ball milling, gravity concentration, intensive cyanide leaching, carbon-in-pulp adsorption, elution, electrowinning and refining. Current reserves and exclusive resources are dated December 31, 2025, while exploration is targeting reserve replacement, the two-kilometre Mine Trend Extension and near-mine satellite opportunities.
