Kloof is a large, shallow to ultra-deep level gold mining and processing operation located in the Far West Rand Goldfield of the Witwatersrand Basin, near the town of Westonaria in the Gauteng Province of South Africa, 70km west of Johannesburg.

As of 31 December 2020, Kloof had surface and underground gold Mineral Reserves of 4.7 million ounces and Mineral Resources of 33 million ounces. underground gold mineral reserves of 4.7 million oz and mineral resources of 33 million oz.

At Kloof, we are focused on optimising the mineral resource, stabilising production profiles at current performance levels, reducing pay limits through quality mining and cost reduction, targeting secondary reefs on an incremental basis above existing infrastructure and the mining of low-grade surface reserves to fill excess metallurgical capacity.

    Kloof was one of the three original assets acquired by Sibanye when Goldfields International completed its February 2013 unbundling transaction. Mining operations have been carried out in the West Rand since the late 19th century and at Kloof in its current form since 2000 when a number of existing mining operations were amalgamated.

    Gold and uranium mineralisation is contained in paleo-placer conglomerates, that are locally known as reefs. The principal mining activity takes place on the Ventersdorp Contact reef with additional reefs mined including the Middlevlei, Kloof and Libanon reefs. The orebody is accessed from the surface via vertical shafts, with the deepest operating level some 3,347m below surface. Mining is focused on open ground and pillars using scattered conventional breast, mini-longwall stoping. Mining operations also take place on surface rock dumps.

    The current mine infrastructure consists of seven shaft complexes, four with sub-shafts and five of which are producing. Two gold processing plants, with No. 1 carbon-in-pulp processing primarily surface rock dump material, and No. 2 carbon-in-pulp processing primarily underground ore at a rate of 347 tonnes per day.

    Tailings are contained in two tailings storage facilities with a combined capacity of 63.6Mt (a surplus of 35Mt over life-of-mine deposition requirements).

    Kloof has a converted mining right issued under the Mineral and Petroleum Resources Development Act valid until 29 January 2027 in respect of a total mining area of 20,087 hectares.
