## Exhibit 99.1

**Exhibit 99.1**

**Taseko ANNOUNCES improved economics FOR its fLORENCE COPPER PROJECT**

**March 30, 2023, Vancouver, BC -** Taseko Mines Limited (TSX: TKO; NYSE American: TGB; LSE: TKO) ("Taseko" or the "Company") is pleased to announce the results of recent technical work and updated economics for its 100%-owned Florence Copper Project, located in Arizona, U.S.A (the 'Florence Copper Project" or "Florence Copper"). The Company has filed a new technical report entitled "NI 43-101 Technical Report - Florence Copper Project, Pinal County, Arizona" dated March 30, 2023 (the "Technical Report") on SEDAR. The technical report was prepared in accordance with NI 43-101 and incorporates updated capital and operating costs for the commercial production facility and refinements made to the operating models, based on the Production Test Facility ("PTF") results.

The technical work completed by Taseko in recent years has been extensive and has de-risked the project significantly. The PTF operated successfully over an 18-month period and provided a valuable opportunity to test operational controls and strategies which will be applied in future commercial operations. In addition, a more sophisticated leaching model has been developed and calibrated to the PTF wellfield performance. This detailed modeling data, along with updated costing, has been used to update assumptions for the ramp up and operation of the commercial wellfield and processing facility.

Project Highlights:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net present value of US$930
million (after-tax, at an 8% discount rate)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Internal rate of return
of 47% (after-tax)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Payback period of 2.6
years

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Operating costs (C1) of
US$1.11 per pound of copper

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Annual production capacity
of 85 million pounds of LME grade "A" cathode copper

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 22 year mine life

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total life of mine production
of 1.5 billion pounds of copper

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total estimated initial
capital cost of US$232 million remaining

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Long-term copper price
of US$3.75 per pound

Stuart McDonald, President & CEO of Taseko, stated, "Despite global cost inflation in recent years, the Florence Copper Project continues to demonstrate robust economics and remains one of the lowest capital intensity copper development projects in the world. The operational experience and technical information that we gained through the PTF testwork has been invaluable and we're well positioned to build and operate the commercial-scale ISCR facility. The new Technical Report includes updated capital cost estimates based on detailed engineering and recent contractor and vendor quotations. The main cost increases relate to construction labour and wellfield drilling costs which impact both initial and sustaining capital costs."

"The inflationary environment we have been in has also driven copper prices higher. With a lack of new mines being developed today and copper's critical role in the global energy transition, the long-term price outlook remains very attractive for copper producers. The low-carbon, low impact production method at Florence Copper is expected to make it a preferred supplier of green, low carbon copper in the US domestic market. With procurement of long-lead items well advanced, we are ready to commence construction of the commercial facility following the issuance of the final UIC permit in the coming months," Mr. McDonald concluded.

**In-Situ Copper Recovery ("ISCR")**

The extraction method proposed for the Florence Copper Project is ISCR. ISCR extracts copper by injecting a weak sulfuric acid solution, referred to as raffinate, through targeted portions of the mineral deposit using an array of injection wells. The raffinate passes through natural fractures and voids in the deposit and dissolves the copper mineralization. The copper laden solution, known as pregnant leach solution ("PLS"), is collected in recovery wells where it is pumped to the surface for processing. Copper is extracted from the PLS using solvent extraction and electrowinning ("SX/EW") techniques producing a saleable copper cathode product.

**Production Test Facility ("PTF")**

Florence Copper operated a demonstration scale ISCR facility referred to as the PTF, where leaching under commercial operating conditions was completed between December 2018 to June 2020. The PTF facilities included an ISCR wellfield, an SX/EW processing plant, an acidic reverse-osmosis water treatment plant, a water impoundment, run-off pond, and associated infrastructure. The PTF wellfield was comprised of four injection wells, nine recovery wells, seven observation wells, and four multilevel sampling wells.

The purpose of the PTF was to demonstrate hydraulic control and confirm the oxide ore zone behaves hydrologically as an equivalent porous media thereby ensuring protection of underground sources of drinking water. Secondly, the PTF provided an opportunity to test operational controls and strategies to inform future commercial scale operations.

The PTF well field is located on the northern portion of the deposit specifically selected in a challenging hydrogeological position to demonstrate hydraulic control. The well field is situated at the edge of a graben with major faults running though the surrounding area. The location was also selected to represent the ore to be leached at the start of commercial production.

The well field was designed using the same well spacing and construction methods as those planned for the commercial-scale ISCR facility. Hydraulic performance data generated during PTF testing and operations have provided important information supporting the design and operations planning for the commercial-scale well field.

Leaching of the PTF wellfield began in December 2018 and continued under commercial operating conditions until June 2020, after which fresh acid addition was stopped and the leaching phase was ramped down and concluded with the shutdown of the process plant by end of October 2020. The PTF well field was then subsequently transitioned into a rinsing phase which is currently still in progress.

The PTF was successful in demonstrating that copper could be produced feasibly and also that hydraulic control of process solutions in the ISCR well field could be established and maintained to ensure protection of underground sources of drinking water. It has also further confirmed that the oxide ore zone behaves hydraulically as an equivalent porous media.

PTF operations provided valuable data to test operational controls and strategies to inform future commercial scale operations. Employment of strategies such as reverse flow, use of inflatable packers to target areas of the formation, and varying acid application rates through increased raffinate injection flows and or acid strengths all proved to be beneficial tools to effectively manage the leaching operation.

**Sweep Efficiency**

Sweep efficiency is defined as the fraction of the pore space contacted or 'swept' by the injected solution as it flows from injection to recovery well. Sweep efficiency increases over time as leaching progresses and more ore is contacted by process solutions. The ultimate sweep efficiency achieved over the duration of leaching indicates the proportion of the ore from which copper will be recovered.

The geophysical monitoring for the central recovery well found that all of the monitored ore zone was contacted by leach solutions in the first five weeks of leaching and achieved 90% overall. This result confirms the projected long-term sweep efficiency of 90% used in the model.

**Overall Recovery Plan**

The total copper recovery to cathode is projected to be 65.8% at an estimated acid consumption of 6.0 lbs/lb copper. PLS grade feeding the SX/EW plant will average 1.7 g/L of copper over the life of the project.

**SX/EW Plant Operations**

The SX/EW process plant operations commenced in mid-March 2019, following a four-month initial leaching period, and was shut down in October 2020, four months after fresh acid addition to raffinate was stopped resulting in a subsequent depletion of PLS copper grades feeding the plant. For the entire PTF operational run, the plant operated at a high average availability of 99.9% and produced a total of 1.1 million pounds of high-grade copper cathode product from the ISCR leach solutions.

**Note to United States Investors**

This news release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. Canadian reporting requirements for disclosure regarding mineral properties are governed by National Instrument 43-101 - Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators ("NI 43-101"). Taseko's estimates of "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" have been prepared in accordance with these NI 43-101 requirements.

Effective February 2019, the United States Securities and Exchange Commission ('SEC') adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers like Taseko whose securities are registered with the SEC under the Exchange Act and as a result, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources". In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be "substantially similar" to the corresponding definitions under the CIM Standards, as required under NI 43-101. For this reason, information contained in this news release regarding the Company's Florence Copper Project may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements under the United States securities laws and the rules and regulations thereunder.

For further information on the differences between the disclosure requirements for mineral properties in the United States and NI 43-101, please refer to the company's Annual Information Form, a copy of which has been filed under Taseko's profile on SEDAR at sedar.com and the company's Form 40-F, a copy of which will be filed on EDGAR at edgar.com.

Note: All currency amounts are stated in US dollars. Measurement units used in this release are in imperial (US).

The Technical Report includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no assurance that the Technical Report will be realized. Investors are encouraged to read the full text of the Technical Report which has been filed on SEDAR and will be also filed on EDGAR (www.sec.gov) and made available on the Taseko website.
