A small diamond mine in a kimberlite pipe, owned by De Beers. The pipe forms part of a cluster of eleven intrusions, most of which are uneconomic. It was discovered in 1906 and worked for about 5 years through weathered ground and a concentration zone near the surface. Below 40 feet, when fresher hard kimberlite was encountered, the diamond grades dropped dramatically, forcing the mine to close in 1912. It was subsequently acquired by De Beers and is currently being redeveloped as a new mine.

Located north of Kroonstad.
