Taseko ANNOUNCES 2020 FINANCIAL & OPERATIONAL UPDATE

January 11, 2021, Vancouver, BC - Taseko Mines Limited (TSX: TKO; NYSE American: TGB; LSE: TKO) ("Taseko" or the "Company") is pleased to provide an update on 2020 financial and operational performance.

Stuart McDonald, President of Taseko, commented, "Given the volatility and challenges brought about by COVID-19 over the past year and the state of the global economy just nine months ago, we are very pleased with our 2020 financial results and optimistic about the year ahead. Adjusted EBITDA* for 2020 is expected to be in the range of $105-110 million, up from $51 million in 2019. Gibraltar produced 123 million pounds of copper for the year and 2.3 million pounds of molybdenum. Looking ahead to 2021, we expect copper production of approximately 125 million pounds from Gibraltar."

Mr. McDonald continued, "Copper prices have continued to strengthen and many analysts are forecasting higher prices going forward, based on the strong demand environment, expected government stimulus programs and investments in renewable energy infrastructure, combined with ongoing mine supply challenges. The current copper price of approximately US$3.65 per pound is roughly US$0.80 per pound higher than the average price in 2020, and at current prices we would have generated around $200 million of Adjusted EBITDA* in 2020, so we are very optimistic about our financial outlook this year.

The improved market conditions are timely as we continue to advance all financing options for the Florence copper project. We ended the year with a cash balance of $85 million, up from $53 million at the end of 2019."

Mined ore grades in October and November impacted production in the fourth quarter, but we finished with a strong December with concentrator throughput above design capacity along with increased copper grades. Additionally, increased oxide ore and ore hardness in the initial Pollyanna Pit benches affected recoveries and throughput in the fourth quarter, both of which have been rectified," concluded Mr. McDonald.

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP performance measure and represents net income before interest, income taxes, and depreciation and also eliminates the impact of a number of items that are not considered indicative of ongoing operating performance.

Adjusted EBITDA is presented as a supplemental measure of the Company's performance and ability to service debt. Adjusted EBITDA is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the industry. Adjusted EBITDA does not have any standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other companies.

Adjusted EBITDA is determined and presented on a consistent basis from period to period and a preliminary estimated range of Adjusted EBITDA for the year ended December 31, 2020 is presented above. We have not yet finalized our operating or financial results for this period, and our actual financing results for the year ended December 31, 2020 remain subject to the completion of our quarter-end and year-end closing process, which includes review by management and our audit committee. While carrying out such procedures, we may identify items that would require us to make adjustments to this preliminary estimated range of Adjusted EBITDA set forth above. As a result, our actual Adjusted EBITDA could be outside of the ranges set forth above and such differences could be material. Additionally, our estimate of Adjusted EBITDA is a forward-looking statement based solely on information available to us as of the date of this press release and may differ materially from our actual operating and financial results as a result of developments that occur after the date of this press release. Therefore, you should not place undue reliance on the preliminary estimate of our Adjusted EBITDA. See "Caution Regarding Forward-Looking Information."

The preliminary estimates of our Adjusted EBITDA have been prepared by, and are the responsibility of, our management. Our independent registered public accountants have not audited, reviewed or performed any procedures with respect to such preliminary estimates of our operating results. Accordingly, KPMG LLP expresses no opinion or any other form of assurance with respect

thereto. The information presented herein should not be considered a substitute for the financial information to be filed with the SEC in our Annual Report on Form 40-F for the year ended December 31, 2020 once it becomes available. We have no intention or obligation to update the preliminary estimates of our operating and financial results set forth below prior to filing that Annual Report.

A reconciliation of Adjusted EBITDA for the nine months ended September 30, 2020 can be found on page 23 of Taseko's Third Quarter MD&A.
