Tsodilo Resources Ltd (CVE:TSD) updated on its BK16 kimberlite project in Botswana, where it is carrying out a bulk sampling program.
The prospect lies within the famous Orapa kimberlite cluster, one of the most prolific diamond-producing areas in the world.
A third parcel of 279 diamonds totalling 43.95 carats has now been delivered to Gaborone in preparation for acid cleaning.
After the diamonds have been acid treated they will be stored at secure facilities with the other BK16 diamonds for valuation and breakage studies, the firm said.
Meanwhile, the processing of the dense media separation (DMS) concentrates of the large diameter drill (LDD) samples through the Bourevestnik (BV) Polus-M X-ray recovery unit has been completed.
Elsewhere, the processing of the DMS concentrates of the LDD tailing samples is still continuing.
"Final diamond counts and weights; detailed breakage descriptions and resorption characteristics; definitions of habit, colour, size distributions; sample grade calculations; and commercial characteristics will be compiled and finalized once all samples and audit samples have been processed, and sorted," Tsodilo said in today's regulatory release.
