A diamond mine in a kimberlite deposit consisting of two dykes, one of which is associated with two pipes. The diamond grades and qualities of the different kimberlite bodies varied considerably. In general, diamonds from the pipes were of poorer quality than those from the dykes. Some parts of the latter contained diamonds of exceptional quality. The mine was considered marginal, and the underground portion was closed following a major accident in the 1990s. In recent years some re-treatment of tailings dumps has taken place, but this has now also ceased.

Later became known as Rovic Diamond Mine.

Located about 40 km east of Boshof.
