Witwatersrand field. A small diamond mine in a kimberlite pipe, discovered in 1890 and mined from a single shaft until the start of the Boer War in 1899. Mining continued after the war until a major aquifer, which was encountered at a depth of 259m, forced the mine to close. It was eventually re-opened by Samada Diamonds Pty Ltd and closed again in the early 1990s.
Located about 7.5 km from Welkom.
