Second quarter production of 27,700 tonnes of copper

VANCOUVER, July 10, 2014 /PRNewswire/ - Capstone Mining Corp. ("Capstone") (TSX: CS) today announced operating results for the three and six months ending June 30, 2014 of its three operating mines: Pinto Valley, Cozamin and Minto. Combined production totalled 27,700 and 55,300 tonnes of copper (in concentrates and cathode) in the second quarter and year-to-date periods, respectively, with additional by-products of zinc, molybdenum, lead, silver and gold.

Q2 2014 Production (tonnes)          
  Q1   Q2   YTD
Pinto Valley          
  Copper in concentrates 16,700   16,900   33,600
  Copper cathode 600   500   1,100
  Pinto Valley Total 17,300   17,400   34,700
  Copper in concentrates 5,100   5,200   10,300
  Copper in concentrates 5,200   5,100   10,300
Total Copper production(1) 27,600   27,700   55,300

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

"At the midway mark of the year our copper production is on plan with all operations performing well," said Darren Pylot, President and CEO of Capstone. "With operations at Pinto Valley now fully ramped up and essentially stabilized at targeted throughput rates we can direct all of our focus on continued cost and business improvements at Pinto Valley."

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.

(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 above. (3) Grade and recoveries were estimated based on concentrate production. Year-to-date includes a 38 tonne adjustment to payable copper related to inventory and final settlements for Pinto Valley. *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.
