2016 Copper Production (tonnes)

    Total copper production (1) 24,600  28,100  32,000  29,900  114,600           108,000

    Totals may not add due to rounding. (1) Total production includes copper in
    concentrate and cathode production. (2) Total copper production guidance of
    108,000 tonnes (+/- 5%) reflects guidance provided on January 18, 2016.
    Production guidance at Pinto Valley and Minto was increased, offsetting reduced
    Cozamin guidance on July 26, 2016.

 "Capstone's 2016 consolidated copper production exceeded guidance, driven primarily by outperformance at Pinto Valley and Minto," said Darren Pylot, President and CEO of Capstone. "Record setting production at both these operations contributed to a year of exceptional operating performance."

Operational Highlights 

  • Copper production at Pinto Valley exceeded expectations, with throughput above plan for the quarter and year. Throughput averaged 56,800 tonnes per day ("tpd") and 56,200 tpd for the fourth quarter and full year, respectively. The operation continued to demonstrate the mine's potential, achieving a new daily throughput record of over 64,000 tpd in December.
  • At Cozamin, the average grade for the quarter of 1.63% copper offset lower than planned mill throughput, with production ending the year at the previously lowered guidance target. Development rates continued to improve through the fourth quarter.
  • At Minto, copper production for the quarter met expectations while full year throughput, grade and recoveries all exceeded plan. In the fourth quarter the mill processed stockpiles, supplemented by underground mining, which continued through the quarter.

    Pinto Valley gold production reaches payable levels from time to time. Any
    payable gold production will be reported in the period revenue is received. At
    Minto, final gold production is not available since assaying is conducted
    off-site, but is estimated above. (3) Grade and recoveries were estimated based
    on concentrate production. *Silver and gold have not been estimated in the
    Pinto Valley resource model. Only recovered silver and payable gold is reported
    for this mine.
