Once the ore has been exposed, we break it up before taking it to be processed.
Our open-pit mines - in Botswana, Canada and South Africa - are impressive feats of engineering, traversed by a variety of Earth moving machinery, hydraulic shovels and trucks with 250 tonne payloads. The layout of each mine depends on the size and shape of the diamond deposit as well as the characteristics of the host rock. When an open-pit mine reaches a certain depth, we may continue to mine the kimberlite pipe by constructing an underground mine.
