indicated)

VANCOUVER, Sept. 8, 2014 /PRNewswire/ – Taseko Mines Limited (TSX:TKO, NYSE
MTK:TGB) (“Taseko” or the “Company”) announces that it has entered into
a definitive agreement (the “Agreement”) whereby Taseko will acquire
all of the issued and outstanding common shares of Curis Resources Ltd.
(“Curis”) under a plan of arrangement pursuant to the Business Corporations Act (British Columbia) (the “Transaction”). Curis is a mineral exploration
and development company whose principal asset is the Florence Copper
Project (“Florence”), an in situ copper recovery and solvent
extraction/electrowinning (“SX/EW”) project located adjacent to the
town of Florence in central Arizona, USA. The Florence deposit contains
approximately 2.4 billion pounds of copper reserves with an average
grade of 0.36% TCu, contained within a measured and indicated resource
of 2.8 billion pounds of copper with an average grade of 0.33% TCu.

Under the terms of the Agreement, each Curis shareholder will receive
0.438 of a Taseko common share for each Curis common share held (the
“Offer”), representing consideration of $1.055 per share based on
Taseko’s 20-day volume weighted average price (“VWAP”) for the period
ending September 5, 2014. The Offer represents a 21% premium to Curis’
20-day VWAP and a 31% premium to Curis’ 60-day VWAP, each for the
period ending September 5, 2014, and based on Taseko’s 20-day VWAP and
60-day VWAP during the same period. Following the completion of the
Transaction, Curis shareholders, excluding Taseko, will hold 12% of the
pro forma company, calculated using basic shares outstanding.

Russell Hallbauer, President and CEO of Taseko stated, “The addition of
the Florence Copper Project to Taseko continues to strengthen the
Company’s near-term development pipeline with an advanced-stage
project. The project is located in a favourable mining jurisdiction
with access to key infrastructure, including power, rail, natural gas
and roads. We believe our board and combined management teams have both
the permitting and technical experience to advance this opportunity to
production in a timely manner. From an operational perspective, Taseko
has the technical experience to effectively build and operate the
Florence SX/EW facilities. The SX/EW plant at our Gibraltar Mine, which
was restarted in 2007, is not unlike the facility which will be
constructed at Florence. If our Gibraltar plant was processing the same
oxide copper grade as Florence, it would produce at roughly half the
capacity of Florence.”

“Florence adds diversity to our pipeline of development projects. There
are very few copper projects in secure jurisdictions which have first
quartile operating costs, such as Florence, and the timing of
anticipated production from the project could be ideal for the next
copper price cycle. Florence’s low initial capital costs should allow
us to manage the project’s funding requirements through to production.”
continued Mr. Hallbauer.

“With our Aley Niobium Project also entering the environmental
assessment phase, we could potentially have two projects ready for
construction in the next 24 months. In an era with few economically
viable projects available, we are in an enviable position.” concluded
Mr. Hallbauer.

Commenting on the Transaction, David Copeland, President and CEO of
Curis stated, “With the announcement today of the acquisition of Curis
by Taseko, I believe there is an opportunity for shareholders of Curis
to benefit from both retained exposure to our Florence Copper Project
and Taseko’s continuing success in operating the Gibraltar Mine and
developing the New Prosperity and Aley Projects. The Transaction also
provides Curis shareholders with access to additional financial
resources to de-risk the funding of the Florence Copper Project,
ownership in a mature, cash flowing producer, as well as enhanced
trading liquidity and analyst coverage.”

Summary of the Transaction

The Transaction is structured as a plan of arrangement and subject to
Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101”) since Taseko currently owns 12,916,667 common shares of
Curis, representing approximately 17.3% of Curis’ outstanding common
shares. The Transaction is subject to the approval of the Supreme
Court of British Columbia and (i) at least two-thirds of the votes cast
by Curis shareholders, (ii) two-thirds of the votes cast by Curis
shareholders and option holders voting as a single class, and (iii) a
majority of the votes cast by disinterested Curis shareholders (as
required by MI 61-101), at a special meeting of Curis shareholders,
which is expected to be held in October 2014. Prior to executing the
Agreement, the board of directors of Curis obtained a formal valuation
from Deloitte LLP as required by MI 61-101. The formal valuation was
prepared under the supervision of a special committee of the board of
directors of Curis consisting of independent directors (the “Special
Committee”) and will be included in the management information circular
to be mailed to Curis shareholders. All Curis shareholders will be
treated on the same basis and no additional consideration or benefit is
available to any Curis shareholder. All Curis option holders will
receive an amount of Taseko shares equal to the ‘in the money’ value of
their Curis options outstanding at the closing date, less any
applicable withholdings.

In addition to the aforementioned approvals, completion of the
Transaction is subject to other customary conditions, including the
receipt of all necessary regulatory approvals. The Transaction is
expected to close in October, 2014.

In the event that the Transaction is not completed, Curis has agreed to
pay Taseko a termination fee of $3 million, under certain
circumstances. Curis has also provided Taseko with certain other
customary rights, including a right to match any superior offers.

The Special Committee, following a review of the terms and conditions of
the Agreement and consideration of a number of factors unanimously
recommended the Transaction to Curis’ Board of Directors. The Special
Committee and the Board of Directors have received an opinion from
Paradigm Capital that as of the date of the opinion and subject to the
assumptions outlined therein, the consideration payable to Curis
shareholders (other than Taseko) under the transaction is fair, from a
financial point of view to Curis. Curis’ Board of Directors, after
receiving the recommendation of the Special Committee and advice from
its advisors (including the opinion from Paradigm Capital), has
unanimously determined that the Transaction is in the best interests of
Curis and is fair to Curis shareholders (other than Taseko) and will
recommend that Curis shareholders (other than Taseko) vote in favour of
the Transaction. All of the directors and senior officers of Curis have
entered into customary lock-up agreements with Taseko pursuant to
which, among other things, they have agreed to vote their shares in
favour of the Transaction.

As part of the Transaction, Taseko has agreed to provide US$2 million of
unsecured short-term financing pursuant to a convertible loan agreement
entered into by Taseko and Curis concurrent with the Agreement. The
proceeds of the loan are intended to ensure Curis has sufficient
liquidity to operate through closing of the Transaction. Taseko has the
right to convert any indebtedness outstanding under the convertible
loan into common shares of Curis at a price of $0.90 per Curis share.

About Curis and Florence Copper

Florence Copper’s March 2013 Pre-Feasibility Study outlines average
annual production of approximately 75 million pounds copper at average
cash operating costs of US$1.11 per pound with an initial capital
requirement of approximately US$210 million.

Florence Copper is engaged in the final stages of permitting for the
Phase 1 Production Test Facility (“PTF”) for an in-situ copper recovery
project in Arizona, USA. The PTF includes a 24-well in-situ recovery
well field and a state of the art solvent extraction/electrowinning
plant that will produce copper cathode. The PTF will assist in the
demonstration of the science and safety of the in-situ process and
provide an opportunity for the public to fully engage and understand
this modern copper extraction technology. Concurrently, Florence Copper
continues to advance engineering, testwork, environmental studies and
permitting for Phase 2 commercial operations.
