NOTICE AND ACCESS NOTIFICATION TO SHAREHOLDERS

ANNUAL GENERAL MEETING OF SHAREHOLDERS

You are receiving this notification because Taseko Mines Limited (the "Company" or "Taseko") has decided to use the notice and access model for the delivery of meeting materials to its shareholders in respect of its Annual General Meeting of Shareholders to be held on Wednesday, July 8, 2020 (the "Meeting"). Under notice and access, instead of receiving paper copies of the Company's Notice of Annual General Meeting, form of Proxy and Information Circular (the "Information Circular") (collectively, the "Proxy Materials") shareholders are receiving this Notice and Access Notification ("notification") with information on how they may access the Proxy Materials electronically. Together with this notification, shareholders will receive a proxy or a voting instruction form, as applicable, allowing shareholders to vote by proxy, so their votes will be counted in the resolution votes at the Meeting. This alternative means of delivery is an environmentally responsible and cost-effective way to deliver Proxy Materials to the Company's shareholders.
