Harry Winston Diamond Corporation (TSX:HW,NYSE:HWD) announced the Diavik Diamond Mine produced 1.93 million carats from 0.52 million tonnes of ore processed in the third quarter of 2012.

As quoted in the press release:

The 19% decline in ore processed in the quarter was due to a shift in production from the lower grade, lower value A-418 open pit to higher grade and higher value ore from the underground mining of the A-154 pipes. Open pit mining of the A-418 kimberlite pipe concluded in September, although processing of open pit ore from the A-418 kimberlite pipe will continue into the fourth calendar quarter of 2012.
