Canadian miner recovers a 341.9 carat gem in Botswana


Canadian junior diamond miner, Lucara Diamond has recovered a 341.9 carat gem quality diamond from its Karowe Mine in Botswana.


With operations in Botswana and Lesotho, Lucara Diamonds on Tuesday said the stone was recovered while processing fragmental kimberlite from the central and south lobe interface in the mine, north-central Botswana.
According to the company the type IIa diamond shows exceptional colour and clarity and is scheduled for sale along with two other greater than 100 carat diamonds, recovered.
“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,” said William Lamb, President and Chief Executive Officer of Lucara.
Meanwhile installation of tracer testing of the new XRT diamond recovery machines started last year has been completed at Karowe Mine. Lucara said 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.
According to Lucara, the XRT technology is capable of delivering separation efficiencies equal to conventional wet processing methods while reducing operational costs and enhancing downstream processing. Enditem
