The sale of the Vaal River mining operations was completed on 28 February, 2018. The Vaal River mining operations, which share a milling and treatment circuit and are located around 180km from Johannesburg, near the Vaal River, on the Free State-North West Province border included:
- Kopanang, which is bound to the south by the Jersey Fault, has a single shaft system to a depth of 2,334m. It exploits the Vaal Reef almost exclusively, producing gold as its primary output and uranium oxide as a by-product. Kopanang Mine and related assets and liabilities have been sold to Heaven-Sent SA Sunshine Investment Company Limited.
- Moab Khotsong, is located in the Free State and has a single shaft system mining to a depth of 3,100m. Given the geological complexity of the Vaal Reef, the mine’s principal reef, scattered mining is employed. Moab Khotsong Mine and related assets and liabilities has been sold to Harmony Gold Mining Company Limited.
