Botswana – Lucara Diamond Corp., the Botswana-focused diamond miner, has recovered a 341.9 carat gem quality diamond from its 100%-owned Karowe mine.

The stone was recovered while processing fragmental kimberlite from the central and south lobe interface.

The Type IIa diamond shows exceptional colour and clarity and will be sold along with two other greater than 100 carat diamonds which have also been recovered.

Plant Optimization Project Progress

Excellent progress continues to be made on the plant optimization project at Karowe. Construction activities are essentially complete and commissioning activities of the final sections has commenced.

Tracer testing of the new XRT diamond recovery machines has been completed. A small volume of material was processed through the machines to check material handling aspects which lead to the recovery of a 7.8 carat diamond. It is expected that the new recovery and XRT sections will be integrated into the main treatment plant before the end of April 2015.

William Lamb, President and CEO, comments, “The recovery of this magnificent stone once again confirms the quality of diamonds contained within the Karowe resource. Timing of the sale of these exceptional stones is still to be decided.”

“The surprise recovery of the 7.8 carat diamond from the very small quantity of material processed during commissioning of the XRT machines demonstrates the excellent recovery capability of this exciting technology. The final integration of the last sections into the process plant will provide improved mine planning flexibility and allow us to once again access material from all three lobes and more importantly provide the ability to mine sustainably from the high value south lobe in the future.”

Karowe has become recognised for its large, gem quality stones. The company has held a few large-stone auctions to accomodate the sale of these large stones.
