LETŠENG DIAMOND MINE
The Letšeng kimberlites are unique and have been a source of intrigue for geologists since their discovery. Not only are the diamond populations atypical, but the way the pipes were formed and their emplacement history is rather unusual. Several features of the two Letšeng pipes (Main and Satellite) differentiate them from the Kimberly-type Pyroclastic Kimberlites and impact our understanding of the distribution diamonds within the pipes.
GHAGHOO DIAMOND MINE
Since mining operations began at Ghaghoo, the focus was on confirming the De Beers historical resource and reserve estimates for the higher grade VKSE domain. Mining started in the south eastern portion of the pipe in the relatively undiluted VKSE ore and progressed towards the central zone containing abundant country rock dilution.
