A diamond mine in a kimberlite pipe, owned by Auridiam Zimbabwe Pty Ltd. It was discovered by De Beers in 1974 during an exploration programme in Zimbabwe. In 1991, the property was acquired by Auridiam. Production started in 1992, and operations were gradually scaled up, but the mine was closed in 1998 due to low diamond prices. Located 12.5 km NW of Beitbridge.
