Lucara Diamond (TSX:LUC) has provided results from the mini bulk sample program on the BK02 kimberlite located 30 kilometres east of the Karowe Mine and an update on other exploration programs.
As quoted in the press release:
A total of 274.33 carats were recovered from the processing of 5,916 tonnes of BK02 for a sample grade of 4.6 cpht (carats per hundred tonne). The largest diamond recovered was a 5.48 carat brownish octahedron (see attached photo). In addition, a total of 24 stones were recovered greater than 1 carat in weight including 3 diamonds in excess of 2 carats.
Sample results confirm that the BK02 kimberlite has a coarse size distribution similar to that observed at Lucara’s Karowe Mine (see attached chart). A limited drill programme is planned for BK02 to better delineate the kimberlite, define internal geology and collect material for microdiamond analyses.
The sample was collected by excavator and trucked to the Karowe Mine where processing was conducted through a 15 tonne per hour custom built Bulk Sample Plant (BSP). Final diamond recovery from DMS concentrate was completed at the BSP using conventional XRay luminescence technology. Diamonds were exported to the Lucara Sales and Sorting office in Gaborone for final cleaning and sizing.
