Increased Production At Mt. Mount Milligan

DENVER, CO - Jacques Perron , President and Chief Executive Officer of Thompson Creek Metals Company, said, "During the first quarter, we remained focused on improving our safety performance, optimizing operations at Mount Milligan, and containing costs at our molybdenum operations. We are pleased with the quarter over quarter increases in throughput, and payable copper and gold production at Mount Milligan, and the 30% decrease in our unit cash costs on a by-product basis, resulting from much higher gold sales revenue compared to the first quarter of 2015. We ended the quarter with approximately $169 million of working capital, which included approximately $139 million of cash."

Perron continued, "Activities relating to the construction of the permanent secondary crushing circuit at Mount Milligan are progressing on schedule and on budget, and we expect to complete construction and commissioning by year end."
