Thompson Creek Announces Davidson Deposit Feasibility Study

• The Davidson Deposit feasibility study estimates that the development of the Davidson Deposit would require a capital expenditure of C$109 million.
• Molybdenum production is estimated at approximately four million pounds per year over a 10-year period. 
• The average annual cash costs are estimated to be US$9.46 per pound. 
• The estimated pre-tax internal rate of return (IRR) is 20% and payback is 3.4 years from the start of full production at the assumed molybdenum prices including a long-term price of US$14 per pound starting in 2012.
• The sensitivity analysis shows the IRR would increase to 43% if molybdenum prices are 20% higher than assumed.

Toronto, ON - April 2, 2008 - Thompson Creek Metals Company Inc. (TSX: TCM / NYSE: TC) (the "Company"), one of the world's largest publicly traded, pure molybdenum producers, today announced the results of the feasibility study on the development of the underground Davidson Deposit near Smithers, British Columbia.

"The Davidson Deposit feasibility study indicates positive project economics," said Kevin Loughrey, Chairman and Chief Executive Officer.  "This is the case even though we make an assumption that molybdenum prices in the later years of the study will be considerably lower than we are receiving currently. We intend to review the details of the study and make a decision in the next few months on whether to proceed with the project.

"We will also be discussing the project with Sojitz Corporation, our joint venture partner with a 25% interest in the Endako Mine, where the Davidson ore would be processed if the project goes ahead. Sojitz has indicated an interest in partial ownership of the Davidson Deposit.

"While the underground Davidson Deposit within Hudson Bay Mountain (nine kilometres northwest of Smithers) has a considerable measured and indicated mineral resource containing molybdenum, the Company requested a feasibility study on mining only a limited portion of the deposit," Mr. Loughrey stated. "This allows us to mine the molybdenum as soon as possible and provides the best opportunity for our shareholders to benefit from high molybdenum prices.

"Our internal expansion projects, consisting of the proposed Davidson mine as well as the Endako expansion conditionally approved by the Board of Directors on March 13, 2008, will comprise a large part of the Company's capital expenditures in the 2008-2010 period," Mr. Loughrey stated. "Total expansion and sustaining capital expenditures over the three years are expected to be approximately C$600 million, with expenditures in any year ranging from C$150 million to C$300 million depending on project timing. We expect that the Company will be able to fund these capital expenditures from internal cash flow.

"Our Endako joint venture partner, Sojitz Corporation, has approved the planned Endako Mine expansion and will participate in the expansion with the company. This project includes increasing the processing capacity of the mill from 28,000 to 50,000 tonnes per day beginning in 2010. Sojitz will contribute 25% of the C$373.6 million total capital cost for the expansion. Thompson Creek's share of the capital cost will be C$280 million.

"We are also pleased to announce that the Endako Mine has received regulatory approval to resume mining in the Endako Pit where a rock slide interrupted activity last November. This provides us with greater flexibility in the months ahead at the Endako Mine where we currently are mining in the Denak West Pit," Mr. Loughrey added.

Davidson Deposit Feasibility Study

The Davidson Deposit feasibility study, compiled by Hatch Ltd. with contributions from several consulting firms, evaluates the potential for mining 2,000 tonnes per day over a 10-year period of the highest-grade molybdenum-containing ore from the deposit and trucking it 200 kilometers to the Endako Mine for processing.

The study assumes that 7.3 million tonnes of proven and probable mineral reserves plus 0.5 million tonnes of sub-grade material will be mined and processed over 12 years, of which 10 years would be at full production. The average grade is estimated at 0.265% contained molybdenum (Mo).

Total molybdenum production after milling and roasting is estimated at 40.3 million pounds Mo or an annual production rate of approximately 4.5 to 5.0 million pounds Mo during the initial full production years, tapering down to average approximately four million pounds per year over the study period.

Mining permits are assumed to be issued in November 2008. First production is expected in August 2009 with full production beginning in April 2010.

The report estimates that capital expenditures of C$109 million would be required to develop the project. This estimate combines a McIntosh Engineering projection of C$65.7 million for underground development and equipment costs and a Hatch estimate of C$43.3 million for surface infrastructure.

The underground development would include the construction of a three-kilometre adit as a haulage ramp from the base of the mountain upward toward the deposit at an incline of approximately 10% and the enlargement of an existing two-kilometre adit to be used for air-intake ventilation and as a secondary access to the deposit.

Major items of surface infrastructure would include a water treatment plant, access roads, on-site buildings, and ore-handling facilities at Endako.

The study estimates operating costs would be C$54.40 per tonne of ore milled, including milling and roasting costs at the Endako Mine.

The average cash cost over the project period is estimated at US$9.46 per pound of molybdenum produced. All cost estimates assume an exchange value for the Canadian dollar of US$0.90.

The study assumes an average molybdenum price over the production period of US$16.13, or about half the current level. The analysis assumes a molybdenum price of US$27 per pound in 2009, US$23 per pound in 2010, US$17.50 per pound in 2011 and US$14 per pound thereafter. The current price for technical grade molybdenum oxide is approximately US$34 per pound.

Based on these estimates for capital cost, operating cost and molybdenum prices, the study estimates an internal rate of return (IRR) before income tax of 20% and a project payback of  3.4 years from the start of full production.

Sensitivity analysis performed by Hatch shows an increase in the IRR to 32% if molybdenum prices are 10% higher than the assumed levels and to 43% if molybdenum prices are 20% higher than the assumed levels. The IRR would be 7% if molybdenum prices are 10% lower than the assumed levels and the project would not have a positive return if molybdenum prices are 20% lower than the assumed levels.

Davidson Mineral Resources and Reserves

The Davidson mine analysis is  based on estimates of mineral resources as of April 10, 2007 by Giroux Consultants Ltd. to the specifications of National Instrument 43-101 and in accordance with the CIM Standards. Based on a cut-off of 0.12% Mo, measured and indicated mineral resources are estimated to be 77.2 million tonnes with an average grade of 0.169% Mo and contained Mo of 288 million pounds. Measured mineral resources are estimated at 45.9 million tonnes with an average grade of 0.18% Mo and contained Mo of 182 million pounds. Indicated mineral resources are estimated at 31.3 million tonnes with an average grade of 0.154% Mo and contained Mo of 106 million pounds.

The study notes that the project's assumed economics, including a long-term molybdenum price of US$14 per pound, result in a cut-off grade of 0.173% Mo. At a cut-off grade of 0.18% Mo, the measured and indicated mineral resources available are approximately 22.7 million tonnes with an average grade of 0.234% Mo and contained Mo of 117 million pounds. Measured mineral resources are estimated at 17.2 million tonnes with an average grade of 0.241% Mo and contained Mo of 91.3 million pounds. Indicated mineral resources are estimated at 5.5 million tonnes with an average grade of 0.215% Mo and contained Mo of 26 million pounds.

The mineral resources at different cut-off grades were estimated by Gary Giroux, P.Eng. of Giroux Consultants Ltd., a "qualified person" as defined in National Instrument 43-101.  

The Company requested that the feasibility study focus on an initial 10-year mine plan. In order to achieve optimum economics, the mine plan is based on a declining cut-off grade strategy starting with a cut-off grade of 0.24% Mo for primary stopes in the first three years of production. This is then lowered to 0.21% Mo for some primary and secondary stopes and lowered again to 0.18% Mo for secondary stopes.

Based on this approach, proven and probable mineral reserves are estimated at 7.3 million tonnes with an average grade of 0.265% Mo and contained Mo of 43 million pounds. Proven mineral reserves are estimated at 6.6 million tonnes with an average grade of 0.268% Mo and contained Mo of 38.9 million pounds, and probable mineral reserves are estimated at 719,000 tonnes with an average grade of 0.238% Mo and contained Mo of 3.8 million pounds.

The mining of mineral reserves over the project period would not inhibit the ability of the Company to mine the remainder of mineral resources available in the Davidson Deposit. 

The mineral reserves were estimated by Ken Collison, P.Eng., Chief Operating Officer, Thompson Creek Metals Company Inc., who is a "qualified person" as defined under National Instrument 43-101, and who has reviewed and approved the contents of this news release.
