Commitments and Contingencies         In the normal course of operations, TCM may be subject to litigation. As of December 31, 2010, there are no material litigation matters.         On December 16, 2010, TCM received a copy of a Notice of Application filed in the Federal Court of Canada by the Nak'azdli First Nation ("Nak'azdli") seeking a judicial review of the decision of the Canadian Minister of Industry approving TCM's acquisition of Terrane. Nak'azdli claims that the Minister failed to consult adequately with Nak'azdli before approving the acquisition. TCM is not named as a party to the judicial review and no claims are made against TCM. TCM intends to take appropriate steps to participate in the judicial review to the extent necessary to ensure that the interests of TCM are protected. Although the Notice of Application states that Nak'azdli are seeking a variety of remedies, including setting aside of the Minister's decision, TCM does not believe that this judicial review will have a material impact on TCM's results of operations or financial condition. TCM is committed to working with First Nations, including Nak'azdli, concerning employment, training and other benefits in connection with the Mt. Milligan Project.         In May 2010, TCM received notification of a petition filed by the Stellat'en First Nation in the Supreme Court of British Columbia claiming that the British Columbia Ministry of Energy, Mines and Petroleum Resources has not fulfilled its duty to consult with or accommodate Stellat'en's asserted aboriginal rights and title interests in relation to the mill expansion project at the Endako Mine. The petition names TCM, a 75% owner of the Endako Mine, as one of the parties involved but does not cite TCM in any of its claims regarding the lack of consultation.         In the normal course of operations, TCM enters into agreements for the purchase of molybdenum. As of December 31, 2010, TCM had commitments to purchase approximately 7.7 million pounds of molybdenum sulfide concentrate throughout 2011, to be priced at a discount to the market price for molybdenum oxide at the time of purchase.         As of December 31, 2010, TCM had contractual obligations related to the mill expansion project at the Endako Mine of $32.6 million (75% share) and contractual obligations related to Mt. Milligan of $105.5 million.         On December 9, 2009, TCM entered into a credit support agreement with British Columbia Hydro and Power Authority ("BC Hydro") related to the mill expansion project at the Endako Mine. Under this agreement, TCM is required to post financial assurance in an amount equal to BC Hydro's estimated out-of-pocket costs for work on the expansion project, estimated at C$16.5 million. Subsequent to the commissioning of the new mill and subject to annual measurements of incremental revenues following the mill's commissioning, some or all of this financial assurance may, thereafter, be released in amounts equal to the incremental revenues generated until such time as the full amount of financial assurance has been released or until such time as the expiration period has been reached. The new mill facility is currently scheduled for completion in late 2011. The amount of the guarantee as of December 31, 2010 was C$16.5 million. As part of the financial guarantee, TCM provided a surety bond to BC Hydro for C$11.2 million for additional financial assurance. The surety bond can be drawn down in the event of a shortfall in incremental revenues after the commissioning of the new mill facility, as discussed above. At this time, TCM does not anticipate having to post any additional financial assurance with respect to the BC Hydro credit support agreement.         As of December 31, 2010, a shortfall in Endako's future electric power usage that would result in incremental payments to BC Hydro cannot be determined and is not deemed to be probable. As such, no accrual has been recorded. An accrual for any expected shortfall will be recorded if and when it is determined that a shortfall is probable and a reasonable estimate can be made. </td></tr></table> 16.
