$28 million

. Adjusted net income* was

$5 million

, or

$0.02

per share.

Total Operating Costs (C1)* (US$ per pound) (CNW Group/Taseko Mines Limited)

Stuart McDonald

, President and CEO of Taseko, stated, "An average realized copper price of

US$4.02

per pound in the first

quarter helped to drive our strong financial performance. Production in the first quarter was 25 million pounds of copper and

234 thousand pounds of molybdenum. Copper head grades for the period were on plan, averaging 0.22%, but production was

slightly below plan due to unexpected mill downtime and operational issues with the primary crushers. Mining advanced deeper

into the

Gibraltar

pit which is the sole source of mill feed this year, and waste stripping ramped up in the new Connector pit.

Initial tons of oxide ore were also mined from the Connector pit and have been placed on leach pads for future production

when the Gibraltar SX/EW plant restarts.

We have decided to defer the in-pit crusher move until the spring of 2024, to coincide with planned work on SAG mill #1 to

minimize concentrator downtime."

Mr. McDonald added, "In the first quarter, we increased our effective interest in

Gibraltar

to 87.5%, after acquiring a 12.5%

stake from one of our joint venture partners. The transaction closed in mid-March and provides immediate 17% growth in our

attributable copper production. Additionally, the five-year deferred payment structure allows Taseko to focus our financial

resources on the construction of the commercial facility at

Florence

."

"In March, we filed a new technical report

**

for the Florence Copper project. The report includes updated capital cost

estimates based on detailed engineering and recent contractor and vendor quotations. Operating and sustaining capital costs

have also been updated, and refinements have been made to the operating models based on the Production Test Facility

("PTF") results. The project has been significantly de-risked in recent years and has an after-tax Net Present Value (8%) of

US$930 million

using a long-term copper price of

US$3.75

per pound. The EPA permitting process continues to advance and

we expect a favourable outcome in the coming months. We are ready to start construction of the commercial production facility

as soon as the final Underground Injection Control permit is issued," continued Mr. McDonald.

"Considering global economic uncertainties, copper markets remain remarkably stable and continue to support a healthy price

of about

US$3.85

per pound. Demand for our product remains strong and the long-term supply/demand fundamentals appear

to be favourable. In the short-term, we continue to maintain our price protection strategy, which provides a minimum copper

price of

US$3.75

per pound for most of

Gibraltar's

production for the balance of 2023. Our original production guidance of 115

million pounds (+/-5%) for 2023 remains unchanged," concluded Mr. McDonald.

OPERATIONS ANALYSIS

First Quarter Review

Gibraltar

produced 24.9 million pounds of copper for the quarter, a 7% decrease over the fourth quarter. Copper production in

the quarter was impacted by low mill availabilities due to poor crusher performance and extended mill shutdowns to

troubleshoot mechanical issues. As a result, mill throughput was approximately 12% below plan for the period.

Copper head grades of 0.22% were in line with recent quarters and management expectations. Copper recoveries in the first

quarter were 80.7% and while above the average achieved for 2022, were impacted by operating variability in the

concentrators.

Mine operations went as planned in the quarter and a total of 24.1 million tons were mined. The ore stockpiles increased by

0.4 million tons in the first quarter and 0.8 million tons of oxide ore from the Connector pit was placed on the heap leach pads.

This oxide ore will be processed in future years when

Gibraltar's

solvent extraction and electrowinning ("SX/EW") plant is

restarted.

Total site costs* at

Gibraltar

of

$112.8 million

were

$6.6 million

higher than last quarter due to greater diesel fuel consumption

from the higher mining rates and increased mill maintenance costs incurred to address mechanical issues.

Molybdenum production was 234 thousand pounds in the first quarter. At an average molybdenum price of

US$32.79

per

pound and with inclusion of the impact of favorable provisional price adjustments, molybdenum generated a by-product credit of

US$0.37

per pound of copper produced in the first quarter.

Off-property costs per pound produced* were

US$0.37

and were generally in line with recent quarters.

Total operating costs per pound produced (C1)* were

US$2.82

for the quarter, compared to

US$3.13

in the same period in

2022 with key variances summarized in the bridge graph below:

GIBRALTAR

OUTLOOK

The

Gibraltar

pit will continue to be the sole source of mill feed in 2023 and the quarterly production profile is expected to be

less variable than 2022 due to improving quality and consistency of ore as mining progresses deeper into the pit. Waste

stripping will continue in the new Connector pit and initial mill feed from this pit is planned for 2024. The in-pit crusher that

currently sits over the Connector ore zone was planned to be relocated in the third quarter of this year, but will now be

deferred to spring of 2024. This results in increased mill production in the current year, and allows the timing of the crusher

move to align with a maintenance shutdown that is required for the mill #1 SAG mill.

The technical information contained in this MD&A related to the

Gibraltar

mine has been reviewed and approved by

Richard

Weymark

, P.Eng., MBA, VP Engineering, who is a Qualified Person in accordance with the requirements of NI 43-101.

Gibraltar

is expected to produce 115 million pounds of copper (+/-5%) in 2023 on a 100% basis.

Strong metal prices combined with our copper hedge protection continues to provide stable operating margins at the

Gibraltar

mine. Copper prices in the first quarter averaged

US$4.05

per pound which is slightly higher than the 2022 average of

US$3.99

per pound. Molybdenum prices are currently

US$20.88

per pound, which is 11% higher than the average price in 2022. The

Company currently has copper price collar contracts in place that secure a minimum copper price of

US$3.75

per pound for 52

million pounds of copper until

December 31, 2023

.

ACQUISITION OF ADDITIONAL 12.5% INTEREST IN

GIBRALTAR

On

March 15, 2023

, the Company completed the acquisition of an additional 12.5% interest in the

Gibraltar

mine from Sojitz.

Gibraltar

is operated through a joint venture which is owned 75% by Taseko and 25% by Cariboo Copper Corporation

("Cariboo"). Under the terms of the agreement, Taseko has acquired Sojitz's 50% interest in Cariboo and now holds an

effective 87.5% interest in the

Gibraltar

mine. The other 50% of Cariboo is held equally by Dowa Metals & Mining Co., Ltd.

("Dowa") and Furukawa Co. Ltd. ("Furukawa").

The acquisition price consists of a minimum amount of

$60 million

payable over a five-year period and potential contingent

payments depending on

Gibraltar

mine copper revenues and copper prices over the next five years. An initial

$10 million

has

been paid to Sojitz on closing and the remaining minimum amount will be paid in

$10 million

annual instalments over the next five

years. There is no interest payable on the minimum amounts and the amounts payable to Sojitz are secured against

shareholder loans owing from Cariboo to Taseko.

The contingent payments are payable annually for five years only if the average LME copper price exceeds

US$3.50

per pound

in a year. The payments will be calculated by multiplying

Gibraltar

mine copper revenues by a price factor, which is based on a

sliding scale ranging from 0.38% at

US$3.50

per pound copper to a maximum of 2.13% at

US$5.00

per pound copper or

above. Total contingent payments cannot exceed

$57 million

over the five-year period, limiting the acquisition cost to a

maximum of

$117 million

.

Taseko will become a party to the existing Cariboo shareholders agreement with Dowa and Furukawa. There will be no change

to the offtake contracts established in 2010 and Dowa and Furukawa will continue to receive 30% of

Gibraltar's

copper

concentrate offtake. There will be no impact to the operation of the Gibraltar Joint Venture.

FLORENCE

COPPER

The Company is awaiting the issuance of the final Underground Injection Control ("UIC") permit from the U.S. Environmental

Protection Agency ("EPA"), which is the final permitting step required prior to construction commencing on the commercial

production facility. The EPA is currently addressing comments that were received during the public comment period, which

was held in the fall of 2022. Public comments submitted to the EPA have demonstrated strong support for the Florence

Copper project among local residents, business organizations, community leaders and state-wide organizations.

In

December 2022

, the Company signed agreements with Mitsui & Co. (U.S.A.) Inc. ("Mitsui") to form a strategic partnership

to develop Florence Copper. Mitsui has committed to an initial investment of

US$50 million

which is conditional on receipt of

the final UIC permit, with proceeds to be used for construction of the commercial production facility. The initial investment will

be in the form of a copper stream agreement on 2.67% of the copper produced at Florence Copper. In addition, Mitsui has the

option to invest an additional

US$50 million

(for a total investment of

US$100 million

) for a 10% equity interest in Florence

Copper.

Detailed engineering and design for the commercial production facility is substantially completed and procurement activities are

well advanced. The Company has purchased the major processing equipment associated with the SX/EW plant and the

equipment has now been delivered to the

Florence

site. The Company is well positioned to transition into construction once the

final UIC permit is received. The Company incurred

$9.9 million

of capital expenditures at the

Florence

project in the first

quarter of 2023.

In

March 2023

, the Company announced the results of recent technical work and updated economics for the Florence Copper

project. 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.

LONG-TERM GROWTH STRATEGY

Taseko's strategy has been to grow the Company by acquiring and developing a pipeline of complementary projects focused

on copper in stable mining jurisdictions. We continue to believe this will generate long-term returns for shareholders. Our other

development projects are located in British Columbia.

Yellowhead Copper Project

Yellowhead Mining Inc. ("Yellowhead") has an 817 million tonnes reserve and a 25-year mine life with a pre-tax net present

value of

$1.3 billion

at an 8% discount rate using a

US$3.10

per pound copper price based on the Company's 2020 NI 43-101

technical report. Capital costs of the project are estimated at

$1.3 billion

over a 2-year construction period. Over the first 5

years of operation, the copper equivalent grade will average 0.35% producing an average of 200 million pounds of copper per

year at an average C1* cost, net of by-product credit, of

US$1.67

per pound of copper. The Yellowhead copper project

contains valuable precious metal by-products with 440,000 ounces of gold and 19 million ounces of silver with a life of mine

value of over

$1 billion

at current prices.

The Company is preparing to advance into the environmental assessment process and is undertaking some additional

engineering work in conjunction with ongoing engagement with local communities including First Nations. The Company is also

collecting baseline data and modeling which will be used to support the environmental assessment and permitting of the

project.

New Prosperity Gold-Copper Project

In late 2019, the Tŝilhqot'in Nation, as represented by Tŝilhqot'in National Government, and Taseko entered into a confidential

dialogue, with the involvement of the Province of

British Columbia

, in order to obtain a long-term resolution of the conflict

regarding Taseko's proposed copper-gold mine previously known as New Prosperity, acknowledging Taseko's commercial

interests and the Tŝilhqot'in Nation's opposition to the project.

This dialogue has been supported by the parties' agreement, beginning

December 2019

, to a series of one-year standstills on

certain outstanding litigation and regulatory matters relating to Taseko's tenures and the area in the vicinity of Teẑtan Biny (Fish

Lake). The standstill agreement was most recently extended for a fourth one-year term in

December 2022

, with the goal of

providing time and opportunity for the Tŝilhqot'in Nation and Taseko to negotiate a final resolution.

The dialogue process has made tangible progress in the past 12 months but is not complete. In agreeing to extend the

standstill through 2023, the Tŝilhqot'in Nation and Taseko acknowledge the constructive nature of discussions to date, and the

future opportunity to conclude a long-term and mutually acceptable resolution of the conflict that also makes an important

contribution to the goals of reconciliation in

Canada

.

Aley Niobium Project

Environmental monitoring and product marketing initiatives on the Aley niobium project continue. The converter pilot test is

ongoing and is providing additional process data to support the design of the commercial process facilities and will provide final

product samples for marketing purposes. The Company has also initiated a scoping study to investigate the potential

production of niobium oxide at Aley to supply the growing market for niobium-based batteries.

The Company will host a telephone conference call and live webcast on Thursday, May 4, 2023 at 11:00 a.m. Eastern Time (8:00 a.m. Pacific) to discuss these results. After opening remarks by management, there will be a

NON-GAAP PERFORMANCE MEASURES

This document includes certain non-GAAP performance measures that do not have a standardized meaning prescribed by

IFRS. These measures may differ from those used by, and may not be comparable to such measures as reported by, other

issuers. The Company believes that these measures are commonly used by certain investors, in conjunction with conventional

IFRS measures, to enhance their understanding of the Company's performance. These measures have been derived from the

Company's financial statements and applied on a consistent basis. The following tables below provide a reconciliation of these

non-GAAP measures to the most directly comparable IFRS measure.

Total operating costs and site operating costs, net of by-product credits

Total costs of sales include all costs absorbed into inventory, as well as transportation costs and insurance recoverable. Site

operating costs are calculated by removing net changes in inventory, depletion and amortization, insurance recoverable, and

transportation costs from cost of sales. Site operating costs, net of by-product credits is calculated by subtracting by-product

credits from the site operating costs. Site operating costs, net of by-product credits per pound are calculated by dividing the

aggregate of the applicable costs by copper pounds produced. Total operating costs per pound is the sum of site operating

costs, net of by-product credits and off-property costs divided by the copper pounds produced. By-product credits are

calculated based on actual sales of molybdenum (net of treatment costs) and silver during the period divided by the total

pounds of copper produced during the period. These measures are calculated on a consistent basis for the periods presented.

Q1 2023 includes the impact from the March 15, 2023 acquisition of Cariboo from Sojitz, which increased the Company's Gibraltar mine ownership from 75% to 87.5%.

Adjusted net income (loss)

Adjusted net income (loss) removes the effect of the following transactions from net income as reported under IFRS:

Unrealized foreign currency gain/loss;

Unrealized gain/loss on derivatives; and

Loss on settlement of long-term debt and call premium, including realized foreign exchange gains.

Management believes these transactions do not reflect the underlying operating performance of our core mining business and

are not necessarily indicative of future operating results. Furthermore, unrealized gains/losses on derivative instruments,

changes in the fair value of financial instruments, and unrealized foreign currency gains/losses are not necessarily reflective of

the underlying operating results for the reporting periods presented.

Adjusted EBITDA

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, many of which present Adjusted EBITDA when reporting their results. Issuers of "high yield" securities also present

Adjusted EBITDA because investors, analysts and rating agencies consider it useful in measuring the ability of those issuers to

meet debt service obligations.

Adjusted EBITDA represents net income before interest, income taxes, and depreciation and eliminates the impact of a number

of items that are not considered indicative of ongoing operating performance. Certain items of expense are added and certain

items of income are deducted from net income that are not likely to recur or are not indicative of the Company's underlying

operating results for the reporting periods presented or for future operating performance and consist of:

Unrealized foreign exchange gains/losses;

Unrealized gain/loss on derivatives;

Amortization of share-based compensation expense.

and economic conditions generally and in particular with respect to the demand for copper and other metals we produce;

uncertainties and costs related to the Company's exploration and development activities, such as those associated with

continuity of mineralization or determining whether mineral resources or reserves exist on a property;

uncertainties related to the accuracy of our estimates of mineral reserves, mineral resources, production rates and timing

of production, future production and future cash and total costs of production and milling;

uncertainties related to feasibility studies that provide estimates of expected or anticipated costs, expenditures and

economic returns from a mining project;

uncertainties related to the ability to obtain necessary licenses permits for development projects and project delays due to

third party opposition;

uncertainties related to unexpected judicial or regulatory proceedings;

changes in, and the effects of, the laws, regulations and government policies affecting our exploration and development

activities and mining operations, particularly laws, regulations and policies;

changes in general economic conditions, the financial markets and in the demand and market price for copper, gold and

other minerals and commodities, such as diesel fuel, steel, concrete, electricity and other forms of energy, mining

equipment, and fluctuations in exchange rates, particularly with respect to the value of the U.S. dollar and Canadian dollar,

and the continued availability of capital and financing;

the effects of forward selling instruments to protect against fluctuations in copper prices and exchange rate movements

and the risks of counterparty defaults, and mark to market risk;

the risk of inadequate insurance or inability to obtain insurance to cover mining risks;

the risk of loss of key employees; the risk of changes in accounting policies and methods we use to report our financial

condition, including uncertainties associated with critical accounting assumptions and estimates;

environmental issues and liabilities associated with mining including processing and stock piling ore; and

labour strikes, work stoppages, or other interruptions to, or difficulties in, the employment of labour in markets in which we

operate mines, or environmental hazards, industrial accidents or other events or occurrences, including third party

interference that interrupt the production of minerals in our mines.
