Imperial Reports 2014 Production

January 26, 2015

Vancouver, January 26, 2015 | Imperial Metals Corporation (III-TSX) reports its 2014 annual base and precious metals production from Mount Polley, Huckleberry and Sterling mines was 41.5 million pounds copper, 33.0 thousand ounces gold and 166.4 thousand ounces silver. Production in 2014 was impacted by the interruption of Huckleberry operations due to a SAG mill bull gear failure on February 26, and the suspension of Mount Polley operations due to the tailings dam breach on August 4. The production represents 97.6%, 92.8% and 102.6% respectively of the targeted copper, gold and silver production reported in the Management’s Discussion & Analysis in the third quarter report.

Commissioning of the Red Chris mine is well underway, and mill operations are expected to commence in late January or early February with production ramp up to follow. This is a significant milestone for the Company. The exploration and development of the Red Chris mine has been a primary focus for Imperial since the property was acquired in 2007.

Power was delivered to the Red Chris mine on November 7, 2014. The Iskut extension of the Northwest Transmission Line (NTL) was built by Highway 37 Power Corp., a subsidiary of Imperial, from the terminus of the NTL at the Bob Quinn substation to a newly constructed substation at Tatogga Lake. A 16 kilometre 287kV power line which connects the Red Chris mine to the Tatogga substation was built by Imperial.

Commissioning of various sections of the 25kV site power systems began immediately following energization of the 287kV power line. The crushing and conveying system is now operational in preparation for commissioning the mill. The reclaim water system has been commissioned, and water supply loops in the plant have been charged with water. The SAG and ball mills are in the final stage of commissioning. Mining is well underway on both the East and Main zones. Mining will initially be from two pits, which will eventually form one large pit.


On August 4, 2014 the tailings dam at Mount Polley mine breached. Since then, Imperial and Mount Polley personnel, and a team of experts with global experience have been working on the rehabilitation and restoration of the breach and surrounding affected areas.

As part of the rehabilitation of lower Hazeltine Creek, two sediment ponds were commissioned in the fourth quarter, resulting in a significant reduction (in excess of 95%) in the turbidity of the water draining into Quesnel Lake. Rehabilitation and restoration work is now focusing on the upper reaches of Hazeltine Creek, and its outlet from Polley Lake.

Approval has been obtained to commence tailings dam embankment repair to a sufficient height so the anticipated Spring runoff does not impact the environment. The government appointed independent expert review panel investigating the root cause of the dam failure is expected to issue their report by January 31, 2015. Alternatives for a modified restart of mine operations have been studied and consulted on with First Nations, and an application has been submitted to the province. In the restart plan, mining would begin in the Cariboo pit with tailings deposited into the Springer pit.

Imperial maintains its resolve to mitigate the effects of the breach. The Company continues to work together with regulators, the local community, the Xat’sull First Nation and the Williams Lake Indian Band.

Mount Polley production for the period up to August 4 when operations were suspended was 24.5 million pounds copper, 25.9 thousand ounces gold and 74.7 thousand ounces silver. Production in 2015 is dependent upon receiving regulatory permission to restart operations.

At Huckleberry the failure of the SAG mill bull gear on February 26 resulted in an interruption of operations until April 6, when the SAG mill was able to continue operating with the damaged bull gear rotating in the opposite direction. Installation of the new bull gear on the SAG mill was completed in December, and the mill has been operating well since.

Imperial’s share of copper production from Huckleberry in 2014 was 17.0 million pounds copper and 91.6 thousand ounces silver, 94.5% and 105% respectively of the targeted production. Imperial’s share of the targeted production for 2015 is approximately 22.0 million pounds copper.
