Totals may not add due to rounding. (1) Total copper production guidance of 90,000 tonnes (+/- 5%) and Pinto Valley guidance reflects guidance provided on January 20, 2015. Production guidance at Minto was increased, offsetting reduced Cozamin guidance on September 9, 2015. (2) Total production includes copper in concentrate and cathode production.
 

"Capstone's 2015 copper production met guidance, with outperformance at Pinto Valley and Minto offsetting the production challenges at Cozamin that occurred early in the year," said Darren Pylot, President and CEO of Capstone. "Pinto Valley had a very strong fourth quarter with record quarterly throughput of over 54,000 tonnes per day, demonstrating significant improvement and exceeding our expectations."

Fourth Quarter Operational Highlights

  • Payable copper shipped for the quarter from all three mines was 22,300 tonnes.
  • Pinto Valley had an exceptional quarter, posting daily, monthly and quarterly throughput records under Capstone's ownership of 60,500, 54,800 and 54,100 tonnes per day ("tpd"), respectively. Both grade and recovery were as planned for the quarter.
  • At Cozamin, the average grade for the quarter of 1.75% copper offset slightly lower mining rates and mill throughput. The mine is continuing to work towards increasing developed stopes, but has largely overcome the issues leading to the production shortfall experienced early in the year.
  • At Minto, a pocket of high grade underground ore in excess of 3% copper in close proximity to existing development was opportunistically mined and processed, resulting in higher grade for the quarter than planned. Stripping of the Minto North pit is proceeding well and the lower-grade ore was reached as expected in December.

(1) Adjustments based on final settlements will be made in future periods. (2) The Pinto Valley molybdenum circuit did not operate in the fourth quarter as a result of below break-even molybdenum prices. (3) Pinto Valley gold production reaches payable levels from time to time. Any payable gold production will be reported in the period revenue is received. At Minto, 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 and gold have not been estimated in the Pinto Valley resource model. Only recovered silver and payable gold 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 extend the lives of our current mines with mineral resource and reserve expansions, maintain optionality on the Santo Domingo development project, prudently progress the exploration portfolio and grow 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.
