Harry Winston Diamond Corporation (TSX:HW,NYSE:HWD) announced the Diavik diamond mine produced 1.79 million carats in the second quarter of 2012.
As quoted in the press release:
For the first half of the calendar year 2012, the Diavik Diamond Mine produced 3.4 million carats from 1.1 million tonnes of ore processed compared to production of 3.1 million carats from 1.0 million tonnes of ore processed in the comparable period of the prior year. Ore volumes processed for the first half of the current year included production from the A-154 South underground using the sub-level retreat mining method that commenced in July 2011. Diamonds recovered for the current year are also higher than in the comparable period of the prior year due partially to increased high-grade ore and lower mud-rich type B ore mined from the A-418 kimberlite pipe in 2012.
