Operations Update:

Mt. Milligan Mine

The Company began the commissioning and start-up phase of Mt. Milligan in the fourth quarter of 2013, and Mt. Milligan Mine reached commercial production, defined as operation of the mill at 60% design capacity mill throughput for 30 days, as of February 18, 2014. The ramp-up at Mt. Milligan continues to progress with mine pit grades as expected, metal recoveries in the mill currently above expectations and mill throughput steadily improving. The Company continues to expect that mill throughput will achieve 75% to 85% of design capacity by the end of 2014. During the first quarter of 2014, the Company made three shipments of copper and gold concentrate under its sales agreements and received provisional payments for two of those shipments. The timing of the gold and copper concentrate shipments and related provisional payments from Mt. Milligan are based on the structure of the Company's sales agreements.

Thompson Creek Mine

At Thompson Creek Mine, molybdenum production for the first quarter of 2014 was better than expected primarily due to higher ore grades and mill recoveries. Typical spring runoff water conditions in late March, which are expected to continue during the second quarter, have impacted mining at the bottom of the pit, where ore grades are higher. Continued efforts to trench water away from the active dig faces have allowed mining at the bottom of the pit to continue, and stockpiled ore has been used to supplement feed to the mill.

Endako Mine

At Endako Mine, molybdenum production for the first quarter of 2014 was lower than expected. Although the mill is optimized to achieve design mill recoveries and better than designed mill throughputs, operational challenges in maintaining a consistent feed from the mine to the mill, tailings operational issues, and lower than expected ore grades during the first quarter adversely impacted production results.
