Profitable Growth Producing Copper, Gold, Silver and Zinc in Canada and Mexico

Message: Capstone Mining Record 2014 First Quarter Production Results

VANCOUVER, British Columbia, April 10, 2014 /PRNewswire/ --

First quarter production of 27,600 tonnes of copper

Capstone Mining Corp. ("Capstone") (TSX: CS) today announced operating results for the three months ending March 31, 2014 of its three operating mines: Pinto Valley, Cozamin and Minto. Combined production totalled 27,600 tonnes of copper (in concentrates and cathode), with additional by-products of zinc, molybdenum, lead, silver and gold.

Q1 2014 Production (tonnes)

    Pinto Valley
    Copper in concentrates       16,700
    Copper cathode                  600
    Pinto Valley Total           17,300
    Copper in concentrates        5,100
    Copper in concentrates        5,200
    Total Copper production[(1)] 27,600

Totals may not add due to rounding. (1) Total production includes copper in concentrate and cathode production.

"All three of our mines performed very well this quarter, with Pinto Valley meeting our expectations and Cozamin and Minto also delivering as planned," said Darren Pylot, President and CEO of Capstone. "Our primary focus remains on stabilizing operations and reducing costs at Pinto Valley. We completed the transfer of all the enterprise operating systems to Capstone in the first quarter and are continuing with a number of initiatives designed to enhance the stability and predictability of production at Pinto Valley."

Operational Highlights

  • Pinto Valley production finished the first quarter essentially on plan, with grade and recoveries offsetting a minor shortfall in throughput. A number of initiatives are underway related to production stability, with March showing an improvement over the first two months of the quarter.
  • Cozamin is also on plan, with average throughput for February and March of over 3,800 tonnes per day making up for an unplanned transformer outage that affected production in January. The higher throughput over the course of the quarter offset minor shortfalls in grade and recovery.
  • Minto also exited Q1 on plan, with strong throughput, mill availability and recoveries compensating for slightly lower grades. The mill achieved a monthly throughput production record in March of 4,222 tonnes per day.
  • Payable copper shipped for the quarter from all three mines was 26,600 tonnes.

(1) Adjustments based on final settlements will be made in future periods.

(2) Final gold production is not available since assaying is conducted off-site, but is estimated as above.

(3) Grade and recoveries were estimated for the first quarter based on concentrate production. *Silver production at Pinto Valley is not yet available since assays are conducted offsite. Capstone will commence reporting of Pinto Valley silver starting later in 2014.

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, committed to the responsible development of our assets and the environments in which we operate. We are focused on copper, with three producing mines; the Pinto Valley copper-molybdenum mine located in Arizona, US, the Cozamin copper-silver-zinc-lead mine in Zacatecas State, Mexico and the Minto copper-gold-silver mine in Yukon, Canada. In addition, Capstone has two development projects; the large scale 70% owned Santo Domingo copper-iron-gold project in Region III, Chile, in partnership with Korea Resources Corporation, and the 100% owned Kutcho copper-zinc-gold-silver project in British Columbia, Canada, as well as exploration properties in Chile and Mexico. 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

Alternative Performance Measures

The item marked with (1) "C1 Cash Cost per Pound of Payable Copper Produced" is an Alternative Performance Measure. This performance measure is included because this statistic is a key performance measure that management uses to monitor performance. Management uses this statistic to assess how the Company is performing to plan and to assess the overall effectiveness and efficiency of mining operations. This performance measure does not have a meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies.
