2015 Fourth Quarter and Full Year Operational Results

  • Record gold production of 146,417 ounces in the fourth quarter as a result of improved grades, bringing total gold production to 505,558 ounces for the year, representing an increase of 11% year-over-year.
  • The mill facility processed 5.2 million tonnes (Mt) of ore or an average of 56,015 tonnes per day (tpd). Although the mill reached record milling rates of 2,750 tpoh during the quarter, mill operating time was at 85% due to unscheduled downtime to replace the SAG mill pulp lifters and the 410-conveyor belt. Both were expected to last to the fourth quarter planned shutdown.
  • Mill operating time for the fourth quarter was at 86%, in line with projections with a planned shutdown in November to replace SAG and ball mill liners on both lines and replace a damaged ball mill trunnion. For the year, mill operating time averaged 84%, slightly below budget of 86%. Higher milling rates (2,680 tpoh) compensated for lower plant operating time.
  • A total of 22 Mt (ore and waste) was mined during the fourth quarter (equivalent to mining rates of 239,000 tpd for Phase 1 and 2). For the year, a total of 90.7 Mt was mined (including 7.1 Mt for Phase 2 pre-stripping), an increase of 18% over 2014.
  • At the end of December, the run-of-mine ore stockpiles totaled 4.8 Mt grading 0.68 g/t (equivalent to 100,000 ounces of gold).
