The Jaguar/Bentley Copper-Zinc-Silver Mine is comprised of two underground mines, Jaguar and Bentley. Reserves at Jaguar were exhausted at the end of 2012 and all mill feed now comes from the higher Zn grade Bentley mine. The operation produces both zinc and copper concentrates with the majority of silver reporting to the copper concentrate. Zinc Production reached 400kt/a in 2015 down from 430kt/a in 2014, production is expected to continue to decline going forward. Based on reported ore reserves the Bentley deposit has a mine life to 2017.
