Re:    Form S-3 Registration Statement

Dear Sirs:

We have acted as British Columbia counsel to Thompson Creek Metals Company Inc., a corporation continued under the laws of British Columbia (the "Company") in connection with a Registration Statement on Form S-3 (the "Registration Statement") filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Act"), relating to the proposed public offering by the Company from time to time of an indeterminate amount of: (A) common shares in its capital, no par value (the "Common Stock"); (B) its debt securities ("Debt Securities") to be issued under one or more indentures which are filed as exhibits to the Registration Statement; (C) first preferred shares, no par value (the "Preferred Stock"), which may be represented by contractual entitlements to Preferred Stock (the "Depositary Shares"); (D) warrants; (E) stock purchase contracts; (F) stock purchase units; (G) guarantees of obligations under the Debt Securities by one or more of the Company’s wholly-owned subsidiaries listed as additional registrants in the Registration Statement (each a “Subsidiary Guarantee”); or (H) any combination of the foregoing (collectively, the "Securities" and individually, a “Security”), including Subsidiary Guarantees by the following subsidiaries of the Company incorporated or organized in British Columbia, Canada (collectively, the “British Columbia Guarantors”): Berg General Partner Corp., Berg Metals Limited Partnership (“Berg LP”), Blue Pearl Mining Inc., Terrane Metals Corp. and Thompson Creek Services ULC.

The Securities may be sold by the Company from time to time as set forth in the Registration Statement (as the same may be amended), the prospectuses which form a part of the Registration Statement (the "Prospectus") and as to be set forth in one or more supplements to the Prospectus or term sheet (each, a "Prospectus Supplement").

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of:

(i)the Registration Statement;

(ii) for each of the Company and the British Columbia Guarantors that is a corporation, its Certificate of Incorporation, Amalgamation or Continuance, Notice of Articles and Articles, and for Berg LP, its Certificate of Limited Partnership and Limited Partnership Agreement (collectively, the “Constating Documents”);

(iii) the Indenture, dated May 11, 2012, between the Company and Wells Fargo Bank, National Association, as Trustee (the “Base Indenture”), as supplemented by the

First Supplemental Indenture, dated May 11, 2012, among the Company, the subsidiary guarantors named therein and Wells Fargo Bank, National Association, as Trustee (the “Supplemental Indenture” and together with the Base Indenture, the “Indenture”), each filed as exhibits to the Registration Statement; and

(iv) certificates of (i) good standing for each of the British Columbia Guarantors, other than Berg LP, and (ii) existence for Berg LP, each dated as ofMarch 12, 2014, issued by the Registrar of Companies of British Columbia (the “Certificates of Good Standing”);

(v) certain resolutions (“Resolutions”) of the board of directors of each the Company (the "Board") and the British Columbia Guarantors, adopted on May 3, 2012 and March 11, 2014 relating to the Supplemental Indenture and the registration of the Securities;

(vi) officer’s certificates of the Company and each of the British Columbia Guarantors (collectively, the “Officer Certificates”), as to certain factual matters affecting the Company and the British Columbia Guarantors, and certifying copies of the Constating Documents and the Resolutions, as applicable.

In arriving at the opinion expressed below, we have relied on, without independent investigation, and have assumed:

(i) the genuineness of all signatures on each document that we have examined;

(ii) the authenticity of all documents submitted to us as originals, the conformity with the originals of all documents submitted to us as copies, whether photostatic, telecopied or otherwise;

(iii) the legal power, capacity and authority of all natural persons signing in their individual capacity;

(iv) the accuracy of all factual matters contained in the Officer Certificates and the attachments thereto;

(v) the Board, including any appropriate committee appointed thereby, and appropriate officers of the Company will take all necessary corporate action to approve the issuance, if any, of each respective Security (each, a "Board Action") and such action will be consistent with the procedures and terms described in the Registration Statement and in accordance with the Constating Documents, Applicable Law (as hereinafter defined), and the rules and regulations of the Toronto Stock Exchange;

(vi) that the laws of the Province of British Columbia will be chosen to govern any agreement relating to the issuance of any stock purchase contract or stock purchase unit, and that such choice is a valid and legal provision. We have assumed that any agreement providing for the issuance of stock purchase contracts or stock purchase units will be duly authorized, executed and delivered by the trustee or stock purchase contract agent, if any (in each case, a "Counterparty"), as the case may be, and that any stock purchase contracts or stock purchase units that may be issued will be

manually authenticated, signed or countersigned, as the case may be, by duly authorized officers of a Counterparty, as the case may be. We have further assumed that any any agreement relating to the issuance of any stock purchase contract or stock purchase unit will be in a standard form and contain no provisions contrary to Applicable Law, including those relating to: (a) public policy considerations which may limit the rights of parties thereto to obtain remedies, (b) claims may become time barred or may be or become subject to set off or counterclaim, (c) provisions in stock purchase contract that imposes penalties or forfeitures, or provides for the recovery of fees and expenses, may be unenforceable to the extent that they would require a party to pay any amounts to another person in respect of fines, penalties or costs levied against or imposed upon such person, or exceeding those awarded to or recoverable by such person, pursuant to applicable laws or the order of a court, (d) Canadian courts will not give monetary judgment in any currency other than that of Canada and such judgment may be based on a rate of exchange in existence on a day other than the date of payment of such judgment, and (e) determinations or demands made pursuant to a stock purchase contract in the exercise of discretion purported to be given to any person in, under or by the stock purchase contract may be unenforceable if made in an unreasonable or arbitrary fashion.

(vii) that in the event the Securities will be sold pursuant to an underwriting or purchase agreement, such agreement will be filed as an exhibit to the Registration Statement under to a Current Report on Form 8-K; and

(viii) that at the time of any distribution of, or trade in, Securities, no order, ruling or decision is in effect that restricts any trade in such securities or that affects anyone who engages in any such trade.

In addition, we have examined and relied, to the extent we deemed proper, on a certificate of an officer of the Company and each of the British Columbia Guarantors as to factual matters, and on originals or copies certified or otherwise identified to our satisfaction, of all such corporate records of the Company and the British Columbia Guarantors and such other instruments and certificates of public officials and other persons as we have deemed appropriate.

For the purposes of the opinion expressed in paragraph 6 below relating to the corporate existence of the British Columbia Guarantors, we have relied on the Constating Documents and the Certificates of Good Standing and we have assumed no change in status of such entities from the date of such certificates.

The Company and each of the British Columbia Guarantors (i) are validly existing under Applicable Law, and (ii) have all requisite corporate or limited partnership power and authority, as applicable, to execute, deliver and perform their respective obligations under the Indenture and the Subsidiary Guarantees to which each such British Columbia Guarantor is a party. The entry into the Supplemental Indenture by each of the British Columbia Guarantors has been duly authorized by each British Columbia Guarantor by all necessary corporate or limited partnership action, and the Supplemental Indenture has been duly executed and delivered by each of the British Columbia Guarantors. The Subsidiary Guarantee of the Debt Securities pursuant to the Indenture by each of the British Columbia Guarantors, upon being duly authorized by all necessary corporate or limited partnership action, as applicable, and executed and delivered by an authorized signatory in accordance with Applicable Law, will be validly authorized, executed and delivered under Applicable Law.

We understand that you wish to file this opinion letter as an exhibit to the Registration Statement, and we hereby consent thereto. Such consent is not an admission that we are in the category of persons whose consent is required under Section 7 of the Act, or the rules and regulations promulgated thereunder. In addition, we also consent to Perkins Coie LLP relying on this opinion for the purpose of delivering its opinion to the Company dated as of the date hereof, in respect of the Registration Statement.
