    Jul 30, 2014During the three months ended June 30, 2014, the Company recognized a noncash writedown on longterm lowgrade ore stockpile inventory of $13.4 million, as a result of an increase in costs added to lowgrade ore stockpiles during the quarter. Fewer ounces mined during the quarter resulted in an increase in the per ounce cost of inventory

  • Mine stockpile design to minimise environmental impact

    Putting the ore onto stockpiles before shipment serves a double purpose. The stockpiles provide a quantity buffer between the arrival of ore trains from the mine and the more irregular departure of ships. But of just as much importance is the effect of stockpiles in blending out variations in ore composition.
