Second Quarter Operational Review

Processed ore was in line with Company budget for the second quarter. The increase in higher copper output for the quarter relative to Q2-2016 is explained by a higher copper head grade and an increase in copper recovery. In the case for gold production, a planned lower head grade and a decrease in the gold recovery resulted in lower gold output over Q2-2016.

Copper recoveries were higher than the same period last year, while gold recoveries during the quarter were in line with Company projections. Gold recovery decreased slightly as expected driven by a 10% increase in the copper content in the concentrate to 22.34% (20.30% in Q2-2016). This increase in the copper content in the concentrate provides a net economic benefit offsetting the resulting decrease in gold recovery. The Company will continue to explore increasing the copper content in the concentrate in the following quarters while increasing the gold recovery.

The operation remains on track to deliver on set guidance throughout the remainder of the year.
