Thompson Creek Announces Increased Reserves and Extended Mine Life for the Endako Mine18:32 EDT Monday, September 12, 2011NYSE: TCTSX: TCM, TCM.WTTSX-V: TRX.WTDENVER, CO, Sept. 12, 2011 /CNW/ - Thompson Creek Metals Company Inc. (the "Company" or "Thompson Creek"), a growing, diversified North American mining company, today announced a 9% increase in mineral reserves from 286.2 million to 312.2 million pounds of contained molybdenum at its Endako molybdenum mine located near Fraser Lake, British Columbia, extending its mine life by nearly 2 years through 2028.Kevin Loughrey, Chairman and Chief Executive Officer of Thompson Creek, commented, "The updated reserves estimate illustrates the significant value of the Endako mine.  The current report has revised our reserves estimates as a result of improved engineering, refined geological modeling and new drilling data.  We believe the resource base at the Endako mine will continue to expand with our 2011 drilling program and future  exploration."Thompson Creek plans to conduct 70,955 feet of drilling at Endako in 2011, with the results of such drilling expected to be reported in the second quarter of 2012.  Thompson Creek is currently constructing a new mill facility at Endako which is expected to increase throughput from 31,000 to 55,000 tons per day, increase recovery from 75% to 79%, and increase total annual production from approximately 11 to 16 million pounds per year (with the Company's 75% share increasing from 6-8 to 11-12 million pounds per year).  The new mill facility is on schedule for completion in the first quarter of 2012.The new mineral reserves and resources estimates were prepared by the Endako mine staff and verified by John M. Marek, P.E. of Independent Mining Consultants ("IMC"), a qualified person as defined in National Instrument 43-101.  The new reserves and resources estimates update those previously released on February 24, 2011.  The new mineral reserves and resources estimates are based on a geologic block model of the Endako deposits assembled by IMC in June 2011 using available diamond drilling data through October 2010 and selected blast hole data through May 31, 2011.  The reserves evaluation used a cut-off grade of 0.018% Mo and were estimated using a long-term molybdenum price of $13.50 CDN/lb or $12.00 US/lb using an exchange rate of CDN$1.125/US$1.00.  The mineral resources evaluation used a cut-off grade of 0.015% Mo pit shells at a molybdenum price of $16.50 CDN/lb or $15.00 US/lb using an exchange rate of CDN$1.10/US$1.00.Endako's proven and probable mineral reserves are estimated to be 340.3 million tons at an average grade of 0.046% Mo containing 312.2 million pounds of molybdenum.  These mineral reserves consist of proven reserves of 140.9 million tons at an average grade of 0.047% Mo containing 133 million pounds of molybdenum and probable reserves of 199.3 million tons at an average grade of 0.045% Mo containing 179.2 million pounds of molybdenum. The previous estimates showed proven and probable mineral reserves of 311.0 million tons at an average grade of 0.046% Mo containing 286.2 million pounds of molybdenum.  The updated estimate adds roughly 26 million pounds of contained molybdenum to the Company's present reserves.Endako's measured and indicated mineral resources (excluding proven and probable mineral reserves) are estimated to be 63.2 million tons at an average grade of 0.030% Mo containing 38.0 million pounds molybdenum.  This includes measured mineral resources of 19 million tons at an average grade of 0.029% Mo containing 10.9 million pounds of molybdenum and indicated mineral resources of 44.3 million tons at an average grade of 0.031% Mo containing 27.1 million pounds of molybdenum.  The previous estimates showed measured and indicated mineral resources of 88.4 million tons at 0.034% Mo containing 60.9 million pounds of molybdenum.The Endako mine also has inferred mineral resources of 54.4 million tons at an average grade of 0.035% Mo containing 37.8 million pounds of molybdenum.  The previous estimates showed inferred mineral resources of 61.5 million tons at an average grade of 0.037% Mo containing 45.0 million pounds of molybdenum.In connection with the new reserve estimates, the mine planning team at Endako developed a new mine plan based on the June 2011 block model.  The resulting plan, which takes into account the increase in production rate attributable to the operation of the new mill facility, extends the life of the mine by 20 months through 2028.  Mr. Marek reviewed the Company's new 18-year mine plan and concluded that "the production targets, mine operating cost forecasts, and the capital cost forecasts are reasonable."Mineral reserves and mineral resources are stated herein in short tons (English) units. Details of the new estimates and mine plan are available in a National Instrument 43-101 technical report filed on SEDAR (www.sedar.com).About Thompson Creek Metals Company Inc.Thompson Creek Metals Company Inc. is a growing, diversified North American mining company.   The Company produces molybdenum at its 100%-owned Thompson Creek Mine in Idaho and Langeloth Metallurgical Facility in Pennsylvania and its 75%-owned Endako Mine in northern British Columbia.  The Company is also in the process of constructing the Mt.
