December 5, 2019, Vancouver, BC - Taseko Mines Limited (TSX: TKO; NYSE American: TGB; LSE: TKO) ("Taseko" or the "Company") announces the following:

"The Tŝilhqot'in Nation as represented by Tŝilhqot'in National Government and Taseko Mines Limited have entered into a dialogue, facilitated by the Province of British Columbia, to try to obtain a long term solution to the conflict regarding Taseko's proposed gold-copper mine currently known as New Prosperity, acknowledging Taseko's commercial interests and the opposition of the Tŝilhqot'in Nation to the Project. While the details of this process are confidential, in order to facilitate a dialogue the parties have agreed to a standstill on certain outstanding litigation and regulatory matters which relate to Taseko's tenures and the area in the vicinity of Teztan Biny (Fish Lake)."

Any statements that express, or involve discussions as to, expectations, believes, plans, objectives, assumptions or future events or performance that are not historical facts, are forward-looking statements.  Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as "outlook", "anticipate", "project", "target", "believe", "estimate", "expect", "intend", "should" and similar expressions.
