Endako Mine
Owner: Thompson Creek Metals Company Inc.
 
The Endako Mine is a primary, surface molybdenum mine located near Fraser Lake, 100 miles northwest of Prince George, British Columbia. The mine is operated as a joint venture with Thompson Creek holding a 75% interest and Sojitz Corporation, a Japanese company, holding a 25% interest.
 
The Endako Mine is a fully integrated facility that began operations in 1965. It includes a concentrator that processes ore through crushing, grinding, and flotation circuits into molybdenum disulfide concentrate, and a multiple-hearth roasting facility that converts the concentrate into technical grade molybdenum oxide.
 
Processing capacity at Endako is approximately 31,000 tons of ore per day. In April 2008, the Corporation began an expansion and modernization project that would increase the mill capacity to 55,000 tons per day. While the expansion project was suspended in December 2008 in response to the economic downturn, it was resumed in August 2009. Construction of a new mill building and installation of new processing equipment is expected to be completed by the end of 2011.
 
The Endako Mine consists of three pits. The Endako Pit, the largest, was the focus of mining activity for many years. In January 2008, mining activity shifted entirely to the Denak West pit and during 2008 the Corporation moved the in-pit crusher from the Endako Pit to an area between the Denak West and Denak East pits and began installing an overland conveyor from that location to the mill. The conveyor commenced transporting ore to the mill in March 2009. Plans call for the creation of a single pit by mining the walls between the three existing pits.
 
Mine life was estimated in 2007 at approximately 26 years assuming a long-term molybdenum price of US$10 per pound and updated costs. Based on existing mineral reserves, the mine life will be reduced to about 16 years when the new mill is operational and is processing ore at the expected rate of 55,000 tons per day. The new reserves and mine life calculations are as of February 14, 2011 and assume a molybdenum price of US$15.00 per pound and updated costs.Click here to view the 43-101 technical report dated February 14, 2011 on the mineral resources and mineral reserve estimates and the life of mine plan.
 
1 The mineral reserve and mineral resource estimates for the Endako Mine are based on a 43-101 technical report prepared for Thompson Creek entitled "Technical Report Endako Molybdenum Mine" and dated February 14, 2011 and filed on SEDAR on February 24, 2011. The mineral reserve estimates for the Endako Mine were prepared by Mr. Marek with a cut-off grade of 0.030% molybdenum sulfide. Mineral reserves are stated on a 100% basis; Thompson Creek owns 75% of the Endako Mine. The mineral reserves at the Endako Mine were estimated using an average long-term molybdenum price of US$12.00 per pound.
 
2 The mineral resources for the Endako Mine were estimated using optimized pit shells at a molybdenum price of US$15.00 per pound. Other than metal price, the same pit shell parameters and modifying factors used to determine the mineral reserves were used to determine the mineral resources. Mr. Marek was the qualified person for the estimation of mineral resources.
