Taseko Updates Operating Status of Gibraltar

TASEKO UPDATES OPERATING STATUS OF GIBRALTAR

July 17, 2017, Vancouver, BC – Taseko Mines Limited (TSX: TKO; NYSE MKT : TGB) ( “Taseko” or the

"Company") is updating the operating status of Gibraltar.

Due to uncontrolled wildfires in the Cariboo, an evacuation order has been issued for Williams Lake and a

number of other smaller communities in the region. This has impacted our employees’ ability to travel to

the mine and Gibraltar has now been temporarily idled. It is unclear when milling and mining operations

will recommence.

There are no fires in the immediate area of Gibraltar which pose any threat to the mine.

This is an evolving situation which management is actively managing to ensure Gibraltar is restarted as

soon as possible.
