DEREGISTRATION OF SECURITIES

Thompson Creek Metals Company Inc. (the “Registrant”) is filing this Post-Effective Amendment No. 1 with respect to each of the following Registration Statements on Form S-8: Registration No. 333-169681 (the “2010 Registration Statement”), Registration No. 333-192493 (the “2013 Registration Statement”), and Registration No. 333-195915 (the “2014 Registration Statement” and, together with the 2010 Registration Statement and the 2013 Registration Statement, the “Registration Statements”) to deregister any and all securities that remain unissued or unsold under the Registration Statements.

Pursuant to the 2010 Registration Statement, the Registrant initially registered (a) 1,000,000 shares of the Registrant’s common stock under the Thompson Creek Metals Company Inc. 2010 Employee Stock Purchase Plan and (b) 3,557,782 shares of the Registrant’s common stock under the Thompson Creek Metals Company Inc. 2010 Long-Term Incentive Plan.

Pursuant to the 2013 Registration Statement, the Registrant registered 700,000 shares of its common stock issuable pursuant to (i) the vesting and exercise of stock options to purchase 400,000 shares of common stock under the Stock Option Inducement Award Agreement, dated November 21, 2013, between the Registrant and Jacques Perron and (ii) the vesting of 300,000 restricted share units under the Restricted Share Unit Inducement Award Agreement, dated November 21, 2013, between the Registrant and Jacques Perron.

Pursuant to the 2014 Registration Statement, the Registrant registered (x) 2,000,000 shares of the Registrant’s common stock under the Amended and Restated Thompson Creek Metals Company Inc. 2010 Employee Stock Purchase Plan and (y) 9,203,994 shares of the Registrant’s common stock (the “LTIP Shares”) under the Amended and Restated Thompson Creek Metals Company Inc. 2010 Long-Term Incentive Plan (the “LTIP”). The LTIP Shares included 2,203,994 shares of the Registrant’s common stock that were authorized for issuance under the Thompson Creek Metals Company Inc. Amended Incentive Stock Option Plan and which were previously registered on a Registration Statement on Form S-8 (Registration No. 333-153219) that was later de-registered.

The Thompson Creek Metals Company Inc. 2010 Employee Stock Purchase Plan, Thompson Creek Metals Company Inc. 2010 Long-Term Incentive Plan, Amended and Restated Thompson Creek Metals Company Inc. 2010 Employee Stock Purchase Plan, Amended and Restated Thompson Creek Metals Company Inc. 2010 Long-Term Incentive Plan, Stock Option Inducement Award Agreement and Restricted Share Unit Inducement Award Agreement are referred to herein, collectively, as the “Prior Plans”, and the shares of common stock registered pursuant to the Registration Statements are referred to herein, collectively, as the “Previously Registered Shares”.

On October 20, 2016, the Registrant completed the previously announced arrangement (the “Arrangement”) pursuant to which Centerra Gold Inc. (“Centerra”) acquired all of the outstanding common shares of the Registrant and, as a result, the Registrant became a wholly-owned subsidiary of Centerra.  As part of the Arrangement, the securities issued under the Prior Plans were exchanged for securities of Centerra and the Registrant terminated all offerings of the Previously Registered Shares and related plan interests pursuant to the Registration Statements.

In accordance with the undertakings made by the Registrant in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the securities that had been registered for issuance that remain unsold at the termination of the offering, the Registrant hereby removes from registration all such securities of the Registrant registered but unsold under the Registration Statements.
