In the bargain it has divested from most of its polished diamond business and exploration and development projects. Currently the company operates five mines in South Africa - Cullinan mine, the Koffiefontein mine and the three fissure mines, Helam, Sedibeng and Star. It also owns one mine in Tanzania after it recently acquired the Williamson mine from De Beers, and is awaiting final approval of its bid for De Beers Kimberley Underground operations.
