TASEKO PROPOSES NAME CHANGE AT UPCOMING ANNUAL GENERAL MEETING

Taseko Mines Ltd. has filed its notice of meeting, management information circular and related documents with securities regulators in connection with its coming annual general meeting of holders of common shares of the company.

The meeting materials, which have been mailed to shareholders, can also be accessed on-line on Taseko's website and under the company's profile on SEDAR+.

Proposed name change

At the coming meeting, the company is proposing a name change to reflect its growing business and expanded asset base in North America. Management believes that it is the right time for a new name that reflects the company today and where it is headed. Subject to shareholder approval at this year's AGM, Taseko will become Trekor Metals Ltd.

Stuart McDonald, president and chief executive officer of Taseko, commented: "Over the last two decades, Taseko has been on a journey -- steadily growing our business and unlocking value in our high-quality portfolio of development assets. We've seized opportunities that others have overlooked and built value for shareholders and the communities where we operate. Our journey will continue as Trekor, a name that embodies our values and reflects our ambition to continue to grow North America's copper sector."
