DENVER, June 2, 2015 /PRNewswire/ - Thompson Creek Metals Company Inc. TC TCM ("Thompson Creek" or the "Company") announced today an update on mill operations and throughput at Mount Milligan Mine.  Over the past few months, various adjustments and modifications were made at Mount Milligan to address operational challenges experienced during the first quarter of 2015. While additional improvements are expected to be completed in the second half of this year, during the month of May, daily mill throughput averaged 50,686 tonnes, and tonnage per operating hour averaged 2,198, compared to 39,569 tonnes and 1,889 tonnes per hour, respectively, for the first quarter of 2015.  Mill availability in May was approximately 96%, compared to 87% in the first quarter.

Throughout the month of May, we experienced steady weekly increases in daily throughput. Additional improvements will be made during future scheduled maintenance shutdowns in the third and fourth quarters of this year, which will impact mill availability; however, we expect to see continuous improvement in average daily mill throughput for the remainder of the year.  We would like to thank our Mount Milligan employees for their tenacity as they worked through the operational challenges in a positive and collaborative manner and recognize their hard work and dedication to continue to improve our performance to achieve our objectives."
