Vancouver-based diamond producer Lucara Diamonds, which operates the Karowe mine, in Botswana, has lowered its full-year production guidance to between 265 000 ct and 285 000 ct, compared with the previously targeted 290 000 ct to 310 000 ct, as a result of lower mined ore volumes in the second quarter. The diamond miner pointed out that mining contractor Aveng Moolman had experienced equipment availability issues at the start of the quarter, ended June 30, resulting in lower-than-planned mined ore volumes.
