Deposit Type

  • Kimberlite


Summary:

Four small diamond pipes (B/K1, B/K9, B/K12 and B/K15) were discovered between 1967 and 1972 in an area 20km east of the Orapa kimberlite pipe. These pipes were grouped to form the Damtshaa Mine, the youngest of the Debswana mines which began operation in 2003, and are managed along with Letlhakane Mine from the Orapa operation. The ore grade for B/K9 and B/K12, the kimberlites currently mined, is about 29 cpht and annual production is a maximum of about 330,000 carats. B/K9, at 11.5 hectares, is the larger of the two mined pipes and has a current area of excavation of about 21 hectares, and a depth below surface of 50m. B/K12 pipe area at surface measures 3.2 hectares and the current area of excavation is 7 hectares, with the pit bottom 63m below ground level.


Mining Methods

  • Truck & Shovel / Loader


Summary:

First discovered in 1966, the Orapa Regime (cluster) consists of Orapa, Letlhakane and Damtshaa Mines, which are open-pit operations using traditional truck and shovel methods, and clustered in a radius of under 25km in the Central District of Botswana.
