The processing of surface rock dumps uses excess capacity available at our underground mining operations:
Waste rock dumps acquired with Mponeng are treated at the Mponeng and Kusasalethu plants.
- At our Free State operations, this depends on the availability of spare mill capacity at our functioning gold plants.
- Waste and waste rock dump deliveries to the Kusasalethu plant supplement mining volumes to ensure sufficient backfill is available for use as support in stoping areas.
- Waste rock dumps in the vicinity of Orkney are treated at the Great Noligwa and Mispah plants.
- Milling of waste rock dumps at the Doornkop plant began in FY18.
- Waste rock dumps acquired with Mponeng are treated at the Mponeng and Kusasalethu plants.
