VANCOUVER, Nov. 20, 2014 - Taseko Mines Ltd. ("Taseko") (TSX:TKO, NYSE MKT:TGB) and Curis Resources Ltd. ("Curis") (TSX: CUV) are pleased to announce today the completion of the previously announced statutory plan of arrangement pursuant to which Taseko has acquired all of the issued and outstanding Curis common shares (the "Transaction"). Under the terms of the Transaction, Curis shareholders will receive 0.438 of a Taseko common share for each Curis common share held. Outstanding options to acquire Curis common shares will be exchanged for Taseko common sharesbased on an exchange formula set forth in the plan of arrangement implementing the Transaction. As a result of the Transaction, Curis has become a wholly owned subsidiary of Taseko.

The Transaction was approved by securityholders of Curis at a special meeting held on November 10, 2014. The British Columbia Supreme Court issued a final order approving the Transaction on November 17, 2014. Curis common shares are expected to cease trading and be de-listed from the Toronto Stock Exchange after the close of trading on or about November 25, 2014. Applications will also be made for Curis to cease to be a reporting issuer in the applicable jurisdictions.

Russell Hallbauer, President and CEO of Taseko, commented, "We strongly believe this transaction creates significant, long-term value for Taseko shareholders. The advanced-stage Florence Copper Project is a high quality asset located in Arizona with large copper reserves, a favourable capital and operating cost structure and access to key infrastructure. With the Curis acquisition now complete we can focus on project development and permitting initiatives for the Florence Copper Project. We feel the project is at the stage where Taseko management can support the Arizona-based Florence project team to achieve significant milestones in the near-term."
