HISTORY: De Beers geologists discovered the Jwaneng pipe in 1973 and, following an agreement with the Botswana government in 1978 on the development of the mine by Debswana, production began in 1982. In 1990, a recrush plant was commissioned, introducing an additional diamond-recovery stage, and in 1995 a fourth stream expansion project to increase ore treatment by one third and carat production by more than 20% was completed.
