Thompson Creek Metals Company Announces Adjournment of

DENVER, CO--(Marketwired - May 9, 2013) - Thompson Creek Metals Company Inc. ( NYSE : TC ) ( TSX : TCM ) ("Thompson Creek" or the "Company") announced that at its 2013 Annual and Special Meeting of Shareholders held earlier today, its shareholders voted to approve the re-election of the Company's Board of Directors, to appoint the Company's independent registered public accounting firm and to approve the compensation of the Company's named executive officers on an advisory basis. The meeting was then adjourned with respect to the proposals to approve the Company's amended and restated long-term incentive plan and amended and restated employee stock purchase plan. The meeting will reconvene on May 29, 2013, allowing shareholders additional time to vote on such proposals.

The rules of the New York Stock Exchange require the affirmative vote of the holders of a majority of all shares of the Company's common stock outstanding to approve the Company's amended and restated equity plans, which is a higher voting standard than was required to approve the Company's other proposals. In addition, brokers do not have discretionary authority to vote on the equity plans and must receive voting instructions from beneficial owners of shares held in street name in order for the shares to be voted on the equity plans. Less than half of the Company's outstanding shares of common stock have been voted on the equity plan proposals. A significant percentage of the votes cast on each of these proposals were voted in favor of such proposals.

"The equity plan proposals are very important to the Company because they enable us to attract, retain and reward high caliber employees and directors and to align the interests of employees and directors with those of our shareholders," stated Kevin Loughrey, the Chairman and Chief Executive Officer of Thompson Creek. "We are encouraged by the favorable support that we have received to date from our shareholders who have voted on the equity plan proposals. Given the higher voting standards and the non-routine nature of the proposals, though, we want to make sure that all shareholders have sufficient time to vote their preferences. We encourage shareholders who have not yet executed a proxy to do so. This will help save us further solicitation costs on the proposals and ensure that they are represented."

During the period of the adjournment, Thompson Creek will continue to solicit proxies from its shareholders with respect to the proposed amended and restated equity plans. Shareholders who have not already done so are encouraged to vote on the proposals. Shareholders who have already voted need not take any action on the proposals, although they may change their votes for the equity plan proposals by executing a new proxy, revoking a previously given proxy or attending the adjourned meeting and voting in person, as set forth in the Company's proxy statement.

The meeting adjournment will be until 10:00 a.m., Mountain Time, on Wednesday, May 29, 2013, at the Company's offices at 26 West Dry Creek Circle, Littleton, CO 80120.

Thompson Creek's proxy materials were filed on www.sec.gov and www.sedar.com on March 27, 2013 and were mailed to shareholders on or about March 27, 2013. Shareholders are urged to read such proxy materials.

If you have not yet voted or wish to change your vote on the second and third proposals found in the Company's proxy statement, the Company urges you to vote pursuant to the instructions provided in your voting instruction form or proxy card. You may also contact Morrow & Co. at (800) 267-0201 if you need assistance with voting.

As noted above, at the meeting today, the Company's shareholders re-elected Denis C. Arsenault, Carol T. Banducci, James L. Freer, James P. Geyer, Timothy J. Haddon, Kevin Loughrey and Thomas J. O'Neil to the Board of Directors, each of whom will serve until the 2014 annual meeting, or until his or her successor is duly elected and qualified. In addition, the Company's shareholders appointed KPMG LLP as the Company's independent registered public accounting firm from its engagement through the 2014 annual meeting, and authorized the Company's Board of Directors to fix its remuneration. The Company's shareholders also approved, on an advisory basis, the compensation of the Company's named executive officers. Detailed results of the vote for the election of directors are set out below.
