Stope voids are backfilled with cemented hydraulic fill or waste rock. Mine access is via a boxcut and decline from the surface. Ore is treated through three-stage crushing, ball milling, flotation and dewatering circuits to produce a gold-rich pyrite concentrate that is exported for smelting. Total gold produced during the year was 36,358 ounces.
