Kusasalethu is located about 90km from Johannesburg, near the border of Gauteng and North West provinces, in the West Witwatersrand Basin where it mines the Ventersdorp Contact Reef as its primary ore body. The mine comprises twin vertical and twin sub-vertical shaft systems, and uses conventional mining methods in a sequential grid layout. Mining is conducted to a depth of 3 388m and is Harmony’s deepest mine. Ore mined is treated at the Kusasalethu plant. A shortened life of mine plan was implemented in FY16. This plan aims to optimise the mine’s cash flow at a higher grade and create a stronger operating margin while providing the flexibility necessary to access the high-grade payshoot of the Ventersdorp Contact Reef below infrastructure, should economic circumstances allow.
