01/13/2015

Vancouver, British Columbia - Capstone Mining Corp. (“Capstone”) (TSX: CS) today announced operating results for the three and twelve months ended December 31, 2014 for its three operating mines: Pinto Valley, Cozamin and Minto. Combined production totalled 23,100 and 103,300 tonnes of copper (in concentrates and cathode) in the fourth quarter and full year 2014, respectively, with additional by-products of zinc, molybdenum, lead, silver and gold.

Total copper production(3) 27,200 27,300 25,700 23,100 103,300 104,800

Totals may not add due to rounding. (1) 2014 guidance +/- 5%. (2) Pinto Valley quarterly production has been adjusted to reflect reconciliations from smelter to mine that lagged in the first part of the year. Adjustments will be done on a monthly basis going forward. (3) Total production includes copper in concentrate and cathode production.

“All three of our operating mines were within the range of their production guidance for 2014, and exited the year running at, or very close to, plan,” said Darren Pylot, President and CEO of Capstone. “Our primary focus continues to be on reducing costs and increasing mill reliability at our Pinto Valley operation and a review of maintenance operating systems is continuing.”

Fourth Quarter Operational Highlights

  • Payable copper shipped for the quarter from all three mines was 23,751 tonnes.
  • At Pinto Valley, throughput was 4% lower than planned for the quarter and grade was slightly lower than planned.
  • At Cozamin, throughput remained strong, however grade was lower than planned. Ongoing ground support remediation activities delayed access to some of the higher grade areas of the mine.
  • At Minto, the mine plan called for a lower fourth quarter as processing transitioned primarily to stockpiled ore, supplemented with underground material from the M-Zone through November and Area 118 underground where mining commenced in December. The mill will continue to process underground and stockpiled ore, with surface mining on hold until receipt of the required permits, expected in March.

(1) Adjustments based on final settlements will be made in future periods. (2) Pinto Valley quarterly production has been adjusted to reflect reconciliations from smelter to mine that lagged in the first part of the year. Adjustments will be done on a monthly basis going forward. (3) Final gold production is not available since assaying is conducted off-site, but is estimated above. (4) Grade and recoveries were estimated based on concentrate production. *Silver has not been estimated in the Pinto Valley resource model. Only recovered silver is reported for this mine.

About Capstone Mining Corp.

Capstone Mining Corp. is a Canadian base metals mining company, focused on copper. We are committed to the responsible development of our assets and the environments in which we operate. Our three producing mines are the Pinto Valley copper mine located in Arizona, US, the Cozamin copper-silver mine in Zacatecas State, Mexico and the Minto copper mine in Yukon, Canada. In addition, Capstone has two copper development projects; the large scale 70% owned copper-iron Santo Domingo project in Region III, Chile, in partnership with Korea Resources Corporation, and the 100% owned copper-zinc Kutcho project in British Columbia, Canada, as well as exploration properties in Chile. Using our cash flow and strong balance sheet as a platform, Capstone's strategy is to continue to grow with mineral resource and reserve expansions and exploration, and through acquisitions in politically stable, mining-friendly regions. We will pace our growth with our financial capacity, ensuring we retain, as a priority, sufficient financial flexibility to meet the requirements of our existing operations and our committed development projects, while maintaining an adequate cushion to deal with market volatility and operating risks inherent in the mining industry. Our headquarters are in Vancouver, Canada and we are listed on the Toronto Stock Exchange (TSX). Further information is available at www.capstonemining.com.
