Overview

“Despite challenging worldwide economic conditions and the softness in copper prices, second quarter results were in line with our expectations and are on target to meet our guidance for the year,” said Darren Pylot, President and CEO of Capstone. “Both operations ran well, copper production increased and cash costs decreased compared to the first quarter of 2012, generating cash flow from operating activities of $28.7 million in the quarter.”

“Our operating cash flow, combined with our cash balance, credit facility and the Korea Resources Corporation joint venture and financing agreement for our Santo Domingo project, give us considerable financial flexibility in these uncertain markets, allowing us to advance our growth plans,” continued Mr. Pylot.
