Improving output at Capstone’s Pinto Valley, strong Minto performance offset Q2 shortfall at Cozamin

Rising grades and an improving performance at base metals producer Capstone Mining’s Pinto Valley, in Arizona, and strong results from Minto, in Canada’s Yukon Territory,  offset the second-quarter production shortfall at Cozamin, in Zacatecas state, Mexico. TSX-listed Capstone on Monday announced operating results for the three and six months ending June 30, reporting consolidated output of 21 100 t of copper for the quarter and 44 800 t of red metal during the first six months of 2015, with added by-products of zinc, molybdenum, lead, silver and gold.
