Blyvoor, which incorporates Doornfontein mine, has underground mining and surface retreatment operations. It is situated near Carletonville, 70km south-west of Johannesburg.
Crown is the world's largest gold surface tailings retreatment facility, reprocessing the large and numerous sand and slimes dumps along the reefs that stretch from east to west just to the south of Johannesburg's central business district.
Ergo was established in 2007 as a joint venture between DRDGOLD and Mintails Limited to recover annd treat surface tailings in the Elsburg Tailings Complex. Now wholly owned by DRDGOLD, Ergo has a network of surface rights that provide access to surface tailings deposited across the western, central and eastern Witwatersrand.
ERPM is situated on the Witwatersran Basin near the town of Boksburg, 25km to the east of Johannesburg. Underground mining was suspended in October 2008 following the cessation of the pumping of underground water for safety reasons. ERPM’s gold production comes from its Cason surface retreatment operation, with the tailings processed through Crown’s Knights plant.
