DENVER, CO, May 20, 2011 /PRNewswire/ - Thompson Creek Metals Company Inc. (the "Company" or "Thompson Creek"), today announced the closing of its previously announced private placement of $350,000,000 in aggregate principal amount of its 7.375% Senior Unsecured Notes due 2018.  The notes are fully and unconditionally guaranteed by the following wholly-owned subsidiaries of Thompson Creek: Thompson Creek Metals Company USA, Thompson Creek Mining Co., Thompson Creek Mining Ltd., Langeloth Metallurgical Company LLC, Terrane Metals Corp., Berg General Partner Corp., Berg Metals Limited Partnership, Cyprus Thompson Creek Mining Company, Long Creek Mining Company, Blue Pearl Mining Inc., Thompson Creek Services ULC and Mt. Emmons Moly Company.  The notes are not convertible into equity of Thompson Creek.  The Company intends to use the proceeds from the notes offering to fund development of its Mt. Milligan copper-gold mine and for general working capital.

The Company also announced its entry into an amendment to its revolving credit facility (the "Credit Facility Amendment") that provides for certain changes to the negative covenants in the revolving credit facility to permit the issuance of the notes as well as giving the Company more flexibility to issue additional debt and make investments and capital expenditures. The Credit Facility Amendment changes the minimum consolidated liquidity test from an on-going covenant that is required to be satisfied at the end of each fiscal quarter to a condition that is only required to be satisfied for 90 days after the Company makes additional borrowings or issues additional letters of credit under the revolving credit facility. The Credit Facility Amendment also modifies the leverage ratio thresholds that are used to determine the interest rate and fees applicable to the revolving credit facility. As a result of these modifications, the Company's borrowing cost under the revolving credit facility will not increase as a result of the issuance of the notes.

The notes have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.  No prospectus has been filed in respect of the notes in Canada, and such notes were issued on a basis exempt from the prospectus requirements, and subject to certain resale restrictions in Canada, under applicable Canadian securities laws.
