Murowa Diamonds recorded a seven percent increase in diamonds recovered during the fourth quarter of 2014, to 130 000 carats from 116 000 carats in the third quarter.
According to Rio Tinto’s fourth quarter 2014 operations review the increase was influenced by an increase in ore processed. Ore processed at the mine jumped from 153 000 tonnes in the third quarter to 160 000 tonnes during the quarter under review.
