The Harry Winston Diamond Corporation has issued its second quarter report for the Diavik Diamond Mine, of which it owns 40%. The company stated that the mine had produced 1.79 million carats out of .5 million tons of ore in Q2. The carats were 11% higher and the ore was 4% higher than in the same period last year. For the first half of 2011, Diavik yielded 3.14 million carats from 1 million tons of ore.

The target for Diavik for 2011 remains at 6.9 million carats, with the forecast for the second half of the year to be higher than the first half. Sub-level retreat mining at A-154 South is expected to yield a higher grade ore. It began in early July.

Harry Winston will have held three rough diamond sales by the end of July. May and June sales showed rising prices. For instance, the rough diamond price per carat of Diavik A-154 South ore was $165 in May and $180 in June. The price per carat of ore from A-154 North was $215 in May and $230 in June.

An updated mine plan will be released later this year.
