Lucara Unearths 692ct. Rough at Karowe
Lucara Diamond Corp. has recovered a 692.3-carat diamond from its Karowe mine in Botswana, the second massive rough from the deposit this month.
The white, type IIa stone came from the EM/PK(S) unit in the south lobe, known for its large, high-quality rough, Lucara said Monday. The miner found the diamond via its XRT unit, which uses X-ray technology to identify huge stones in large pieces of ore before they get broken up.
The new discovery is the fourth diamond over 300 carats that Lucara has unearthed so far this year, including one earlier this month: a high-quality white, type IIa rough weighing 1,080.1 carats, which the miner announced on August 8.
