Dominion Diamond Corporation  issued an updated reserves and resources statement and an updated “reserves-only” life of mine plan for the Diavik Diamond Mine recently.  The Company added an additional 3.9 million tonnes containing approximately 13.0 million carats to the mineral reserves.

“As of December 31, 2014, the Diavik Diamond Mine had 18.1 million tonnes of proven and probable mineral reserves containing 53.3 million carats of diamonds (compared to 16.4 million tonnes of proven and probable mineral reserves containing 46.8 million carats as of December 31, 2013),” the Company said in its statement on reserves and resources on a 100% basis for the Diavik Joint Venture, in which it has a 40% share.

At the A-21 pipe, 3.7 million tonnes containing 10 million carats have been upgraded to proven reserve material, the Company stated. Also, at the A-154 North pipe, 0.24 million tonnes of inferred resources at depth were upgraded to probable mineral reserve status. “Within the remaining reserve at the A-154 North pipe, 0.5 million tonnes were promoted from probable reserve to proven reserve, supported by sampling in the active mine which improved confidence for production forecasting,” the Company added. “Routine mine sampling, delineation drilling and mine surveying have increased forecast grade to the existing mineral reserves at the A-154 South, A-154 North and A-418 pipes.”
