Thompson Creek Metals Company Inc. ("Thompson Creek" or the "Company") today announced that the Company's new Mt. Milligan mine commenced production of copper-gold concentrate in September 2013. Concentrate is being accumulated and stored at site until the Company commences transportation for off-site treatment and refinement. Transportation and sale of concentrate are expected to commence in the fourth quarter.
Since commencement of production, the mill has produced approximately 500 tonnes of saleable concentrate having a specification of approximately 25% copper and 30 grams per tonne gold. During the present phased start-up of the mill, the throughput rate is 1,500 to 2,000 tonnes per hour. The processing plant is currently operating with one of the two ball mills. The second ball mill, along with its primary related flotation circuit, and the pebble crusher are still in the commissioning and start-up phase. The full production design throughput rate for the mill is 2,750 tonnes per hour.
Kevin Loughrey, Chairman and Chief Executive Officer of Thompson Creek, said, "The production of copper-gold concentrate is another important milestone for Mt. Milligan and our Company.
