"Copper production in the second quarter from Pinto Valley and Cozamin was within our guided range," said Darren Pylot, President and CEO of Capstone. "An optimization review at Pinto Valley is underway, with a number of opportunities identified that are expected to have a positive impact on production going forward."

"The Minto sale to Pembridge Resources Plc is expected to close later this month," continued Mr. Pylot.

Operational Summary 

• At Pinto Valley, production increased compared with the first quarter as result of higher than planned grade and improved recoveries. Production remains within the guided range at the mid point of the year, with the mine plan calling for rising grade in the second half of the year versus the first half.
• At Cozamin, copper production for the quarter was as planned. Zinc production increased from the prior quarter as processing of zinc development ore began to ramp up from the San Rafael zinc zone.
• At Minto, production for the quarter was lower than planned as a number of modifications to the mine plan were made. The transaction for the sale of Minto to Pembridge Resources is expected to be completed within the next few weeks.
