Diamond production from the Diavik mine in Canada jumped 22 percent in the third quarter as processing volumes and recovered grades both increased, Dominion Diamond Corporation reported.
Output rose to 1.54 million carats in the three months that ended September 30. Processing volumes grew 22 percent because of higher ore availability, particular from pipe A-418, which experienced poor ground conditions in the same period a year ago.
Dominion’s share of production stood at 618,000 carats, according to the miner, which owns 40 percent of the project. Rio Tinto, which owns the remainder, said its share of output was 927,000 carats.
In the first nine months of the year, total mine production increased 2 percent to about 5 million carats. Dominion’s share of output was 2 million carats and Rio Tinto’s 3 million carats.
