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

As of 31 December 2018, Driefontein has total surface and underground gold mineral reserves of 3.32 million oz and mineral resources of 19.22 million oz.   

At Driefontein, we’re focused on optimising the mineral resource, stabilizing production profiles at current performance levels, reducing pay limits through quality mining and cost reduction and targeting secondary reefs on an incremental basis above existing infrastructure.

    Driefontein was one of the assets acquired by Sibanye when Goldfields International completed its February 2013 unbundling transaction. Mining operations have been carried out in the Far West Rand Goldfields since the late 19th century and at Driefontein since the 1930’s.

    Gold and uranium mineralization is contained in paleo-placer conglomerates, locally termed reefs. The principal mining activity takes place on the Carbon Leader Reef, which constitutes almost 62% of Driefontein’s mineral reserves. Additional reefs mined include the Ventersdorp Contact Reef and the Middlevlei Reef.  The orebody is accessed from surface via vertical shafts, with the deepest operating level some 3,240 m 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 six producing shaft complexes, including four sub-shafts, one tertiary shaft and one single lift shat, and three gold processing plants – No. 1 carbon-in-pulp, processing underground ore and low-grade surface rock dump material, and No. 2 carbon-in-pulp and No. 3 carbon-in-leach, each processing only low-grade surface rock dump material.

    Ore is processed at Driefontein at a rate of approximately 240 kilotonnes per month. Tailings are contained in three tailings storage facilities with a combined capacity of 79.4 m tonnes (a surplus of 40.9 m tonnes over life-of-mine deposition requirements).

    Driefontein has a converted mining right issued under the Mineral and Petroleum Resources Development Act valid until 29 January 2037 in respect of a total mining area of 8,561.2 ha while an application to incorporate the Driefontein 4 tailings storage facility into the Driefontein mining right is currently pending.

    The surface rock dumps at Driefontein were depleted in 2018. Driefontein’s two surface treatment plants will be utilised in connection with the Far West Gold Recoveries Project by DRDGOLD.
