It said the Lulo kimberlite bulk sample KBS/164/02, totalling 365m3 of kimberlite material was processed through the Lulo Kimberlite Bulk Sample Plant, yielding 16.32 carats at a recovered grade of 4.47cphm3, with the largest diamond recovered weighing 2.38 carats.

This is the highest grade yet recovered from a Lulo kimberlite bulk sample and is very encouraging for an early-stage sample.
Kimberlite L164 is located south (upstream) of the Canguige Catchment area and was placed on the priority kimberlite bulk sample list due to its indicator mineral content.
Kimberlite L056 is located near mining block 57 and is adjacent to the Canguige catchment.
