Summary:

The Liqhobong Mine lease area contains a cluster of at least five diamondiferous kimberlite bodies; namely the Main Pipe, Satellite Pipe, Discovery Blow, the Blow and a NW-SE striking dyke that is traceable from the perimeters of both the Main and Satellite Pipes. The surface areas of these pipes and blows are ~8.5 hectares, 1.6 hectares, 0.15 hectares and 0.1m hectares respectively. All the currently known five diamondiferous kimberlites of the Liqhobong cluster are within a strike length of at least 2.5 km (Leroux, 2010). Both blows and the Satellite Pipe are generously endowed with kimberlite indicator minerals (KIMs) occurring as xenocrysts. The main pipe is comparatively less enriched in the kimberlite indicator minerals but has abundant olivine macrocrysts and mantle xenoliths, the latter which commonly bear the KIMs.
