Taseko Commences Judicial Review Application

December 2, 2013

VANCOUVER, Dec. 2, 2013 /PRNewswire/ – Taseko (TSX: TKO) (NYSE MKT: TGB) (the
“Company”) has commenced a federal judicial review, seeking to set
aside certain findings of a review panel report relating to the
Company’s New Prosperity Gold-Copper Project environmental assessment.

Taseko is asking the court for a declaration that certain panel findings
relating to seepage and water quality be set aside, and that the Panel
failed in certain respects to comply with principles of procedural

The judicial review will address the question of whether Natural
Resources Canada (“NRCan”) – and in turn the panel – made a fundamental
error when determining expected seepage rates from the tailings storage
facility. Taseko believes the evidence is clear that NRCan failed to
account for a liner that would be part of the tailings storage facility
– thus modeling the wrong project design and assuming water would seep
into open ground.

The Canadian Environmental Assessment Agency (“CEAA”) requested Taseko’s
response to several questions regarding this matter and the Company has
provided that information in letters dated November 8 and November 15,
2013 to the Minister of Environment and to CEAA respectively which are
publicly available.

“Taseko had no choice but to file this application in order to comply
with a 30 day time limit,” said Taseko President and CEO Russell
Hallbauer. “But we remain of the view that the federal government
should allow the project to proceed to the next stage of detailed
permit-level examination and if so the judicial review would not need
to proceed,” added Mr. Hallbauer.

The panel found that the project was not likely to have significant
adverse effects in approximately 30 different areas including human
health, salmon habitat and wildlife. Those findings are not being

15, 2013 letters to the Minister of Environmental are available at
