Second quarter production of 19.3 million pounds of copper in concentrates


Vancouver, British Columbia - Capstone Mining Corp. ("Capstone") (TSX: CS) today announced operating results for the three and six months ended June 30, 2013 of its two operating mines, Cozamin and Minto. Combined production totalled 19.3 and 37.9 million pounds of copper in concentrates in the second quarter and year-to-date period, respectively, with additional by-products of zinc, lead, silver and gold.

"Both operations continued to run well in the quarter, each breaking mill throughput records," said Darren Pylot, President and CEO of Capstone. "At Cozamin, we were able to completely make up for the first quarter production shortfall and ended the quarter with production back on plan. At Minto, year-to-date production is on plan, and we are adding resources to ensure we catch up mining from the pit wall failure that occurred in the fourth quarter of 2012."

Operational Highlights for the Three and Six Months Ended June 30, 2013
  • Production of 19.3 and 37.9 million pounds of copper contained in concentrates, respectively.
  • By-product production of 4.2 and 9.2 million pounds of zinc, 1.1 and 2.0 million pounds of lead and 478,573 and 880,845 ounces of silver in concentrates. Final gold production is not available since assaying is conducted off-site, but is estimated at 2,839 and 6,341 ounces for the respective periods.
  • At Cozamin, additional short and long term sources of water were secured, resulting in higher second quarter throughput rates that have production for the year back on plan as of June 30. In the second quarter, the mill broke both monthly (3,685 tonnes per day in May) and quarterly (3,548 tonnes per day) throughput records.

    Costs on a per pound basis are higher than planned due to the effect of a strengthening Mexican Peso, additional costs to secure water sources and higher contractor costs for haulage. Costs for the remainder of the year are expected to run at the top end of Cozamin's 2013 C1 cash cost(1) guidance of $1.00 to $1.10 per pound.
  • At Minto, operations continued to improve in the second quarter. The mill is running very well and broke a monthly throughput record, processing 4,154 tonnes per day in May. Ore that was deferred from the fourth quarter of 2012, due to the stability issues in the west pit highwall, was accessed in the first quarter and the mining rate now needs to increase to get to the high grade ore planned for later in the year. Site personnel have taken advantage of additional dig faces to increase the mining rate, and are working with the mining contractor to improve operating flexibility and productivity. Expenditures for the quarter were in line with expectations; however, unit costs were lower than expected due to additional deferral of stripping costs.

Alternative Performance Measure

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. This performance measure should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.

Cautionary Note to United States Investors

This news release contains disclosure that has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of U.S. securities laws. Without limiting the foregoing, this news release uses the terms "indicated" and "inferred" resources. U.S. investors are cautioned that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. U.S. investors are cautioned not to assume that all or any part of indicated resources will ever be converted into reserves. U.S. investors should also understand that "inferred resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of "inferred resources" will ever be upgraded to a higher category. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically. Accordingly, information concerning descriptions of mineralization and resources contained in this news release may not be comparable to information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.
