TASEKO ANNOUNCES AT-THE-MARKET OFFERING

Taseko Mines Ltd. has entered into an equity distribution agreement dated May 3, 2023, providing for an at-the-market equity offering program with National Bank Financial, Canaccord Genuity and Stifel GMP, and their respective U.S. affiliates.

The ATM will allow Taseko, through the agents, to offer and sell from time to time in Canada and the United States, through the facilities of the Toronto Stock Exchange and the NYSE American LLC, such number of common shares as would have an aggregate offering price of up to $50-million (U.S.). Sales of the common shares, if any, will be made in transactions that are deemed to be at-the-market distributions as defined in National Instrument 44-102 (Shelf Distributions) and an at-the-market offering as defined in Rule 415 under the U.S. Securities Act of 1933, as amended, including sales made by the agents directly on the TSX, the NYSE American, or any other trading market for common shares in Canada and the United States, or as otherwise agreed between the agents and the company. The company has applied to the TSX and NYSE American for listing of the common shares that may be issued under the ATM, and sales will be subject to the receipt of the required stock exchange approvals. The common shares sold under the ATM will also be admitted to trading on the London Stock Exchange.

The ATM will be effective until May 26, 2025, unless terminated before such date in accordance with the equity distribution agreement. The timing and extent of the use of the ATM will be at the discretion of the company. Accordingly, total gross proceeds from sales made under the ATM, if any, could be significantly less than $50-million (U.S.).

The company intends to use any proceeds from the ATM for its general corporate purposes, which may include: (i) capital expenditures for the company's Gibraltar mine; (ii) expenses associated with the development of the company's Florence copper project; (iii) expenditures on Taseko's other projects; and (iv) general corporate and working capital purposes.

The sale of the company's common shares through the ATM will be made pursuant to, and qualified in Canada by, a prospectus supplement dated May 3, 2023, to the base shelf prospectus of the company dated April 25, 2023, and in the United States pursuant to a prospectus supplement dated May 3, 2023, to the company's final base shelf prospectus contained in the company's effective registration statement on Form F-10 (file No. 333-271142), filed with the U.S. Securities and Exchange Commission. The prospectus supplement (together with the base prospectus) will be available on the SEDAR website maintained by the Canadian Securities Administrators, and the U.S. prospectus supplement (together with the related base prospectus) will be available on the SEC's website. Printed or electronic copies of the documents can also be requested by contacting the company's corporate secretary by mail at 1200, 1040 West Georgia St., Vancouver, B.C., Canada, V6E 4H1, by e-mail at investor@tasekomines.com or by phone at 1-778-373-4533.
