Operational Highlights

• Pinto Valley grade and recoveries more than offset lower than planned throughput. One of the six ball mills was down for 25 days in May, as a result of a gear failure. Repairs were completed by June 4, and the mill operated at capacity for the month of June.
• At Cozamin, strong throughput offset slightly lower grade than planned. Grade is forecasted to improve in the third quarter in accordance with the 2014 mine plan.
• At Minto, lower grade than expected in the open pit was largely offset by continuing very strong throughput and recoveries. The mill achieved a quarterly throughput record of 4,124 tonnes per day. Ore from the underground M-Zone began feeding the mill in April, with grade and tonnage as planned.
• Payable copper shipped for the quarter from all three mines was 24,564 tonnes.

Production Outlook

Capstone's 2014 guidance for 102,000 tonnes 5% of copper in concentrates, at a C1 cash cost(1) of US$1.90 to US$2.00 per pound of payable copper, net of by-product credits and selling costs, remains unchanged.

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.
