Gem lowers full-year production guidance

London-listed Gem Diamonds, which operates the Letšeng mine, in Lesotho, has lowered its production guidance for the full-year to December 31 to between 110 000 ct and 114 000 ct, compared with the previously guided 123 000 ct to 127 000 ct. The diamond miner noted in a trading update to shareholders on October 28 that the processing plants at Letšeng had experienced a number of interruptions and unplanned downtime during the third quarter of the year as a result of a breakdown of the jaw crusher in the primary crushing area (PCA), unplanned failures of key mainstream units at both plants, extreme weather conditions and intermittent external power outages and lost shifts as a result of cross-border travel limitations owing to Covid-19.
