    1 Adjusted EBITDA removes unrealized gains/ losses on derivative
      instruments and foreign exchange gains/ losses



Jim O'Rourke, President and CEO of Copper Mountain, remarked "This quarter marks our 6(th) consecutive quarter of improved production. This continued improvement is a result of the mines focus on integrating the three temporary portable crushers into the circuit to pre-crush a portion of the SAG mill feed. These temporary solutions have been successful in increasing throughput and will remain in place until the permanent secondary crusher is installed this summer. The 2014 first quarter production results are in line with our annual production guidance of 80 -90 million pounds of copper, despite some unscheduled downtime in March. The operational highlights for this first quarter include better than expected grade, improved mill availability and steady progress in mill throughput. These combined factors contributed to record production during the quarter".

Mr. O'Rourke continued, "Overall, construction of the secondary crusher is progressing on budget and on schedule for a mid-summer 2014 start-up. Structural steel is being erected and foundations for the new conveyor systems are in progress."

Copper Mountain Mine

During the period, the company completed a total of three shipments of concentrate containing approximately 19.7 million pounds of copper to Japan for smelting and recorded revenues, net of smelter charges and pricing adjustments, of $61.2 million, realizing a gross profit of $1.1 million. The total cash cost of copper sold for the three months ended March 31, 2014 was US$2.08 per pound of copper after gold and silver by-product credits.

The Copper Mountain Mine achieved record first quarter copper production. Total production for the three months ended March 31(st), 2014 at Copper Mountain Mine was 19.1 million pounds of copper, 5,400 ounces of gold and 105,300 ounces of silver. This represents a 35% growth in copper production from the same period last year.

SAG Mill throughput was improved during the quarter as a result of adding the third portable crusher late last year. Copper production during the quarter was in line with guidance, despite some unscheduled down time in March resulting from a ball mill transformer failure. Mill crews completed repairs in a timely manner and identified the root cause of the transformer failure. A permanent solution has been identified and will be implemented across all six mill transformers over the next four months. During the quarter the mill averaged 91% availability.

A permanent secondary crusher is being installed at the site at a capital cost of $40 million. Progress is on budget and on schedule for a mid-summer start-up. This crusher will replace the three temporary high cost portable crushers and will provide 100% minus 2 inch feed to the SAG mill. Currently the mill is operating at the planned capacity of 32,000 tpd with about 35% of the mill feed being crushed to the 2 inch size range.

Mining activities continued to shift more towards Pit 3 during the quarter and mining in the Pit 2 area shifted more towards the southwest end of the Pit. During the quarter a total of 13.6 million tonnes of material was mined, including 4.1 million tonnes of ore and 9.5 million tonnes of waste. The mine moved an average of approximately 160,000 tonnes of material per day. The Komatsu haul fleet continues to have favourable mechanical availability.
