PROSPECTUS SUPPLEMENT

To a Short Form Base Shelf Prospectus dated April 25, 2023

NEW ISSUE May 3, 2023

TASEKO MINES LIMITED

Up to US$50,000,000 of Common Shares

This prospectus supplement (this "Prospectus Supplement") of Taseko Mines Limited (the "Company" or "Taseko"), together with the short form base shelf prospectus dated April 25, 2023 (the "Base Prospectus" and, together with the Prospectus Supplement, the "Prospectus"), qualifies the distribution of common shares (the "Offered Shares") of Taseko, having an aggregate sale price of up to US$50,000,000 (or the equivalent in Canadian dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold) (the "Offering"). See "Plan of Distribution".

The outstanding common shares of the Company (the "Common Shares") are listed for trading on the Toronto Stock Exchange (the "TSX") under the symbol "TKO", on the NYSE American LLC (the "NYSE American") under the symbol "TGB", and on the London Stock Exchange (the "LSE") under the symbol "TKO".  On May 2, 2023, the last trading day prior to the date of the public announcement of the Offering, the closing price of the Common Shares on the TSX was C$2.24, on the NYSE American was US$1.64 and on the LSE was GB£1.30. Taseko has applied to list the Offered Shares distributed hereunder on the TSX and the NYSE American. Listing will be subject to Taseko fulfilling all listing requirements of the TSX and the NYSE American. The Offered Shares will also be admitted to trading on the LSE.

Taseko is permitted under a multijurisdictional disclosure system adopted by the securities regulatory authorities in Canada and the United States to prepare this Prospectus Supplement and the accompanying Base Prospectus in accordance with the disclosure requirements of Canada. Prospective investors in the United States should be aware that such requirements are different from those of the United States. Financial statements included or incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") and are audited in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), however, are also subject to Canadian auditing and auditor independence standards and thus may not be comparable to financial statements of United States companies.

i

Purchasers of the Offered Shares should be aware that the acquisition or disposition of the Offered Shares may have tax consequences both in the United States and in Canada. Such consequences for purchasers who are resident in, or citizens of, the United States or who are resident in Canada may not be described fully herein. Prospective purchasers are advised to consult their own tax advisors regarding the application of Canadian or United States federal income tax laws to their particular circumstances, as well as any other provincial, state, foreign and other tax consequences of acquiring, holding or disposing of the Offered Shares and related securities. See "Certain Canadian Federal Income Tax Considerations" and "Material United States Federal Income Tax Considerations for U.S. Holders".

Your ability to enforce civil liabilities under the U.S. federal securities laws may be affected adversely because Taseko is incorporated under the laws of Canada, some of its officers and directors and some or all of the experts named in this Prospectus Supplement and the accompanying Base Prospectus are Canadian residents, and a substantial portion of its assets are located outside of the United States.

NEITHER THE SEC, NOR ANY STATE SECURITIES REGULATOR HAS APPROVED OR DISAPPROVED THE SECURITIES OFFERED HEREBY OR PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

Taseko has entered into an equity distribution agreement dated May 3, 2023 (the "Distribution Agreement"), with National Bank Financial Inc. ("NBF"), Canaccord Genuity Corp. ( "Canaccord") and Stifel Nicolaus Canada Inc. ("Stifel" and, together with NBF and Canaccord, the "Canadian Agents") and National Bank of Canada Financial Inc. ("NBF US"), Canaccord Genuity LLC ("Canaccord US") and Stifel, Nicolaus & Company, Incorporated ("Stifel US" and together with NBF US and Canaccord US, the "U.S. Agents" and, together with the Canadian Agents, the "Agents"), pursuant to which the Company may offer and issue the Offered Shares from time to time through the Agents in accordance with the terms of the Distribution Agreement. The Offering is being made concurrently in Canada under the terms of this Prospectus Supplement and in the United States under the terms of the Company's registration statement (the "U.S. Registration Statement") on Form F-10 (SEC File No. 333-271142), as amended, filed with the United States Securities and Exchange Commission (the "SEC"), of which this Prospectus Supplement forms a part.

Sales of the Offered Shares, if any, under this Prospectus Supplement and the accompanying Base Prospectus are anticipated to be made in transactions that are deemed to be "at-the-market distributions" as defined in National Instrument 44-102 - Shelf Distributions ("NI 44-102") and an "at-the-market offering" as defined in Rule 415 under the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), involving sales made directly on the TSX, the NYSE American, or on any other trading market for the Common Shares in Canada or the United States. The Agents are not required to sell any specific number or dollar amount of Common Shares but will use their commercially reasonable efforts consistent with their normal sales and trading practices to sell the Offered Shares offered by this Prospectus Supplement following the instruction of Taseko to proceed with sales of Offered Shares under the Distribution Agreement. Subject to the pricing parameters in a placement notice, the Offered Shares will be distributed at the market prices prevailing at the time of the sale. As a result, prices at which Offered Shares are sold may vary as between purchasers and during the period of distribution. See "Plan of Distribution". There is no minimum amount of funds that must be raised under the Offering. This means that the Offering may terminate after only raising a small portion of the offering amount set out above, or none at all.  The Canadian Agents will only sell Offered Shares on marketplaces in Canada, and the U.S. Agents will only sell Offered Shares on marketplaces in the United States. See "Plan of Distribution".

Taseko will pay the Agents up to 3% of the gross proceeds from the sale of the Offered Shares pursuant to the Distribution Agreement (the "Commission"). In addition, the Company has agreed to reimburse certain expenses of the Agents in connection with the Distribution Agreement.  See "Plan of Distribution" for a description of compensation payable to the Agents.

The net proceeds that Taseko will receive from sales of the Offered Shares will vary depending on the number of shares actually sold and the offering price for such shares, but will not exceed US$50,000,000 in the aggregate. See "Use of Proceeds" for how the net proceeds, if any, from sales under this Prospectus Supplement will be used.

In connection with the sale of the Offered Shares on our behalf, the Agents may be deemed to be an "underwriter" within the meaning of Section 2(a)(11) of the U.S. Securities Act, and the compensation of the Agents may be deemed to be underwriting commissions or discounts. The Company has agreed to provide indemnification and contribution to the Agents against certain liabilities, including liabilities under the U.S. Securities Act.

ii

No Agent of the at-the-market distribution, and no person or company acting jointly or in concert with an Agent, may, in connection with the distribution, enter into any transaction that is intended to stabilise or maintain the market price of the securities or securities of the same class as the securities distributed under this Prospectus Supplement, including selling an aggregate number or principal amount of securities that would result in the Agents creating an over-allocation position in the securities.

An affiliate of NBF, National Bank of Canada ("NBC") is a lender to the Company under the Company's US$50 million revolving credit facility (the "Credit Facility"). Consequently, the Company may be considered to be a connected issuer of NBF under applicable securities laws in certain Canadian provinces and territories. See "Plan of Distribution - Conflict of Interest".

An investment in the Offered Shares is highly speculative and involves significant risks that you should consider before purchasing such Offered Shares. You should carefully review the "Risk Factors" section of this Prospectus Supplement, the accompanying Base Prospectus and the documents incorporated by reference herein and therein as well as the information under the heading "Cautionary Note Regarding Forward-Looking Information".

Peter Mitchell and Rita Maguire, directors of the Company, reside outside of Canada. Peter Mitchell and Rita Maguire have each appointed McMillan LLP, located at Suite 1500 - 1055 West Georgia Street, Vancouver, British Columbia V6E 4N7, as their agent for service of process in British Columbia.  Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person or company that is incorporated, continued or otherwise organized under the laws of a foreign jurisdiction or resides outside of Canada, even if the party has appointed an agent for service of process. See "Agent for Service of Process".

The head office of the Company is located at 12th Floor, 1040 West Georgia Street, Vancouver, British Columbia, V6E 4H1.  The registered office of the Company is located at Suite 1500, 1055 West Georgia Street, Vancouver, British Columbia V6E 4N7.

All references in this Prospectus Supplement to "dollars", "C$" or "$" are to Canadian dollars, unless otherwise stated. References to "US$" or "U.S.$" are to United States dollars.

Prospective investors should rely only on the information contained in or incorporated by reference into this Prospectus Supplement and the accompanying Base Prospectus. Neither the Company nor the Agents have authorized anyone to provide prospective investors with different or additional information. Information contained on the Company's website shall not be deemed to be a part of this Prospectus Supplement or the accompanying Base Prospectus or incorporated by reference herein or therein and should not be relied upon by prospective investors for the purpose of determining whether to invest in the Offered Shares. Neither the Company nor the Agents are making an offer of the Offered Shares in any jurisdiction where such offer is not permitted. A prospective investor should assume that the information appearing in this Prospectus Supplement or the accompanying Base Prospectus is accurate only as of the date on the front of those documents and that information contained in any document incorporated by reference herein or therein is accurate only as of the date of that document unless specified otherwise. The Company's business, financial condition, results of operations and prospects may have changed since the date of this Prospectus Supplement.

IMPORTANT NOTICE ABOUT INFORMATION IN THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this Prospectus Supplement, which describes the terms of the Offered Shares being offered and also adds to and updates information contained in the accompanying Base Prospectus and the documents incorporated by reference therein. The second part, the accompanying Base Prospectus, gives more general information, some of which may not apply to the Offered Shares being offered under this Prospectus Supplement. This Prospectus Supplement is deemed to be incorporated by reference into the Base Prospectus solely for the purpose of the Offering constituted by this Prospectus Supplement. Other documents are also incorporated, or are deemed to be incorporated by reference, into the Base Prospectus and reference should be made to the Base Prospectus for full particulars thereof.

The Company has filed the Base Prospectus with the securities commissions in each Canadian province and territory (the "Canadian Qualifying Jurisdictions") in order to qualify the offering of the securities described in the Base Prospectus in accordance with National Instrument 44-102 - Shelf Distributions ("NI 44-102").  The British Columbia Securities Commission issued a receipt dated April 26, 2023 in respect of the final Base Prospectus as the principal regulatory authority under Multilateral Instrument 11-102 - Passport System, and each of the other commissions in the Canadian Qualifying Jurisdictions is deemed to have issued a receipt under National Policy 11-202 - Process for Prospectus Review in Multiple Jurisdictions. 

The Base Prospectus also forms part of the U.S. Registration Statement that we filed with the SEC under the U.S. Securities Act utilizing the multijurisdictional disclosure system.  The U.S. Registration Statement was declared effective by the SEC under the U.S. Securities Act on April 27, 2023 (SEC File No. 333-271142).  The U.S. Registration Statement incorporates the Base Prospectus with certain modifications and deletions permitted by Form F-10. This Prospectus Supplement is being filed by us with the SEC in accordance with the instructions to the SEC Form F-10.

Investors should rely only on the information contained in or incorporated by reference in this Prospectus Supplement and the accompanying Base Prospectus. The Company has not authorized anyone to provide investors with different or additional information. Neither the Company nor the Agents are making an offer of the Offered Shares in any jurisdiction where such offer is not permitted. An investor should assume that the information appearing in this Prospectus Supplement or the accompanying Base Prospectus is accurate only as of the date on the front of those documents and that information contained in any document incorporated by reference herein or therein is accurate only as of the date of that document unless specified otherwise. The Company's business, financial condition, results of operations and prospects may have changed since those dates.

Market data and certain industry forecasts used in this Prospectus Supplement and the accompanying Base Prospectus and the documents incorporated by reference herein and therein were obtained from market research, publicly available information and industry publications. The Company believes that these sources are generally reliable, but the accuracy and completeness of this information is not guaranteed. The Company has not independently verified such information, and it does not make any representation as to the accuracy of such information.

The Company's annual consolidated financial statements that are incorporated by reference into this Prospectus Supplement and the accompanying Base Prospectus have been prepared in accordance with IFRS, as issued by the IASB and are audited in accordance with the standards of the PCAOB. This Prospectus Supplement and the accompanying Base Prospectus are part of the Company's U.S. Registration Statement. This Prospectus Supplement and the accompanying Base Prospectus do not contain all of the information set forth in the U.S. Registration Statement, certain parts of which are omitted in accordance with the rules and regulations of the SEC, or the schedules or exhibits that are part of the U.S. Registration Statement. Investors in the United States should refer to the U.S. Registration Statement and the exhibits thereto for further information with respect to the Company and the Offered Shares.

Material Risks

The Company's actual results could differ materially from those anticipated. Management has identified the following risk factors which could have a material impact on the Company or the trading price of its Common Shares:

•uncertainties about the future market price of copper and the other metals that we produce or may seek to produce;

•changes in general economic conditions, the financial markets, inflation and interest rates and in the demand and market price for our input costs, such as diesel fuel, reagents, 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;

•uncertainties related to the Florence Copper Project execution plan, including inflation risk and the potential impact of supply chain disruptions on our construction schedule, which could impact the transition into construction operations after the final permit is received from the EPA;

S-3

•uncertainties relating to the satisfaction of the conditions for the advance of the US$50 million deposit under our copper stream agreement with Mitsui for the construction of the Florence Copper commercial facility and our US$25 million equipment commitment from Bank of America Leasing and Capital, LLC;

•uncertainties relating to our ability to secure premium pricing for copper produced at the Florence Copper facility based on its low-carbon characteristics;

as well as those factors referred to in the "Risk Factors" section of this Prospectus Supplement and the accompanying Base Prospectus.

Material Assumptions

The forward-looking statements in this Prospectus Supplement are based on material assumptions, including the following, which may prove to be incorrect:

•the price of copper and other metals will not decline significantly or for a protracted period of time;

•our mining operations will not experience any significant production disruptions that would materially affect our production forecasts or our revenues;

•our estimates regarding future capital and operating costs, including factoring in potential inflation impacts, at Gibraltar will be accurate;

•the results from our operations of the Production Test Facility ("PTF") and updated technical report at Florence Copper will continue to support that commercial operations at Florence Copper are technically and economically feasible;

•we will be able to obtain any remaining construction financing necessary for us to advance Florence Copper to a positive construction decision and eventual commercial production;

•we will be able to obtain the required permits necessary for us to proceed with construction and commercial operations at Florence Copper;

•we will be able to satisfy the conditions for the advance of the US$50 million deposit under our copper stream agreement with Mitsui for the construction of the Florence Copper facility;

•potential supply chain disruptions and associated logistical challenges will not significantly impact our planned capital projects, including our expected development of Florence Copper;

•potential future litigation regarding Florence Copper will not materially impede or delay our ability to proceed with construction and commercial operations at Florence Copper;

•there are no changes to any existing agreements or relationships with affected First Nations groups which would materially and adversely impact our operations;

•there are no adverse regulatory changes affecting any of our operations;

•exchange rates, inflationary pressure on prices of key consumables, costs of power, labour, material costs, supplies and services, and other cost assumptions at our projects are not significantly higher than prices assumed in planning;

•our mineral reserve and resource estimates and the assumptions on which they are based, are accurate;

•our estimates of reclamation liabilities, mine closure costs and bonding needs are accurate;

•we will continue to generate positive cash flows from Gibraltar and be able to secure additional funding necessary for the development and continued advancement of Gibraltar and our development projects, including Florence Copper;

S-5

•our ability to execute our business plans for 2023 and beyond, as discussed in the anticipated use of proceeds; and

•our ability to satisfy the requirements of the TSX and the NYSE American in connection with the listing of the Offered Shares each respective stock exchange.

This list is not exhaustive of the factors that may affect any of our forward-looking statements. Forward-looking statements are statements about the future and are inherently uncertain, and our actual achievements or other future events or conditions may differ materially from those reflected in the forward-looking statements due to a variety of risks, uncertainties and other factors, including, without limitation, those referred to in this Prospectus Supplement and the accompanying Base Prospectus under the heading "Risk Factors" and in the 2022 AIF.

Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. The forward-looking statements contained in this Prospectus Supplement, the accompanying Base Prospectus and the documents incorporated by reference herein and therein are based on the beliefs, expectations and opinions of management as of the date hereof. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers and investors should not place undue reliance on forward-looking statements. Taseko does not intend to update forward-looking statements, except as required by law.

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING
CANADIAN MINERAL PROPERTY DISCLOSURE STANDARDS

We are permitted under a multijurisdictional disclosure system adopted by the securities regulatory authorities in Canada and the United States to prepare this Prospectus Supplement in accordance with the disclosure requirements of Canada. Prospective investors in the United States should be aware that such requirements are different from those of the United States.

The Company is subject to the reporting requirements of the applicable Canadian securities laws, and as a result reports the mineral reserves and mineral resources of the projects it has an interest in according to Canadian standards. Technical disclosure regarding our properties included herein and in the documents incorporated herein by reference has not been prepared in accordance with the requirements of U.S. securities laws.

Unless otherwise indicated, all mineral reserve and mineral resource estimates included in this prospectus and the documents incorporated by reference herein have been prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements (the "SEC Modernization Rules") for issuers whose securities are registered with the SEC under the United States Securities Exchange Act of 1934, as amended (the "Exchange Act"). The SEC Modernization Rules replaced the historical disclosure requirements for mining registrants that were included in SEC Industry Guide 7. As a foreign private issuer that files its annual report on Form 40-F with the SEC pursuant to the multijurisdictional disclosure system, the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Standards. If the Company ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the multijurisdictional disclosure system, then the Company will be subject to the SEC Modernization Rules which differ from the requirements of NI 43-101 and the CIM Standards.

As a result of the adoption of the SEC Modernization Rules, 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 CIM Standards that are required under NI 43-101.  Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms are "substantially similar" to CIM Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.

THE COMPANY

The following description of the Company is, in some instances, derived from selected information about us contained in the documents incorporated by reference into this Prospectus Supplement. This description does not contain all of the information about us and our properties and business that you should consider before investing in any securities. You should carefully read the Prospectus Supplement and the accompanying Base Prospectus, including the section titled "Risk Factors", as well as the documents incorporated by reference into this Prospectus Supplement and the accompanying Base Prospectus, before making an investment decision.

Taseko is a copper-focused mining company that seeks to create long-term shareholder value by acquiring, developing, and operating large tonnage mineral deposits in North America which are capable of supporting a mine for decades. The Company's principal operating asset is the 87.5% owned Gibraltar mine, which is located in central British Columbia and is one of the largest copper mines in North America. Taseko also owns Florence Copper, which is projected to be a low-cost copper producer, expected to manufacture high quality copper cathode in the United States, with potential to secure premium pricing based on its low-carbon characteristics. Taseko also owns the Yellowhead copper, New Prosperity gold-copper, and Aley niobium projects.

S-9

Name, Address and Incorporation

Taseko was incorporated on April 15, 1966 under the laws of the Province of British Columbia and is governed by the Business Corporations Act (British Columbia). The Company’s registered office is located at Suite 1500, 1055 West Georgia Street, Vancouver, British Columbia, V6E 4N7, and its operational head office is located at 12th Floor, 1040 West Georgia Street, Vancouver, British Columbia, V6E 4H1. Taseko operates its business through its subsidiaries, as described in the 2022 AIF.

Taseko is a reporting issuer in all of the provinces and territories of Canada. The Common Shares are listed on the TSX and LSE under the trading symbol "TKO" and on the NYSE American under the trading symbol "TGB".

Inter-Corporate Relationships

The following illustrates Taseko's corporate structure, as more particularly detailed in the 2022 AIF:

S-10

Gibraltar

Our principal operating asset is our 87.5% interest in the Gibraltar mine in British Columbia, Canada. Gibraltar is the second largest open pit copper mine in Canada, having produced 97 million pounds of copper and 1.1 million pounds of molybdenum (on a 100% basis) in 2022. Gibraltar has an expected mine life of at least 22 years based on proven and probable sulphide mineral reserves of 676 million tons at a grade of 0.25% copper as of December 31, 2022.¹

Between 2006 and 2013, the Company expanded and modernized the Gibraltar mine ore concentrator, added a second ore concentrator, increased the mining fleet and made other production improvements at the mine. Following this period of mine expansion and capital expenditure, Gibraltar has achieved a stable level of operations and the Company's focus is on further improvements to operating practices to reduce unit costs and increase production.  The Company increased its effective ownership stake in Gibraltar from 75% to 87.5% in 2023.

Florence Copper

Taseko is proceeding with the development of Florence Copper in Arizona. Once completed and in operation, Florence Copper is projected to be a low-cost producer of low carbon copper in the United States.

The development of Florence Copper is occurring in two phases. For the first phase, Florence Copper completed construction of a PTF in 2018 with PTF wellfield operations commencing in the fourth quarter of 2018. Operation of the PTF wellfield performed to its design and the small-scale Solvent Extraction/ Electrowinning (“SX/EW”) plant produced 1.1 million pounds of copper cathode before the leaching test phase was completed in June 2020. The PTF operation is now finishing its final rinsing process which is expected to be completed later this year. The second phase of Florence Copper will be the construction and operation of the commercial in-situ copper recovery facility.

In December 2020, the Company received the Aquifer Protection Permit from the Arizona Department of Environmental Quality. The Company is awaiting the issuance of the commercial UIC permit from the 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 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.

Detailed engineering and design for the commercial production facility is substantially completed and procurement activities are well advanced. The Company has purchased the major long-lead processing equipment associated with the SX/EW plant and the equipment has now been delivered to the Florence site.

The Company's latest technical report on Florence published on March 30, 2023 estimates remaining capital costs for the commercial facility of US$232 million. At a copper price of US$3.75 per pound, Florence Copper is expected to generate an after-tax internal rate of return of 47%, an after-tax net present value of US$930 million at an 8% discount rate, and an after-tax payback period of 2.6 years. 

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, which is exercisable by Mitsui within a three-year period following completion of construction of the commercial production facility.  As part of the arrangement, Taseko and Mitsui have entered into an offtake contract for 81% of the copper cathode produced at Florence Copper during the initial years of production. Refer to the 2022 AIF for additional details regarding the Mitsui copper stream arrangement.

In January 2023, the Company received an underwritten commitment for US$25 million from Banc of America Leasing and Capital, LLC. Proceeds from this financing will be available to fund costs associated with the SX/EW plant for the Florence Copper commercial production facility. Financing is subject to execution of definitive documentation, customary closing conditions, and receipt of the UIC permit.

S-11

Other Development Projects

We have a diverse pipeline of wholly-owned development projects at various stages of technical and economic feasibility studies, including the Yellowhead copper project, the Aley niobium project, and the New Prosperity gold and copper project.

Business Strategy

Our 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.  All of our producing and development projects are located in British Columbia and Arizona. Our project focus is currently on the development of Florence Copper.

RISK FACTORS

Investing in our securities is speculative and involves a high degree of risk due to the nature of our business and the present stage of its development. The following risk factors, as well as risks currently unknown to us, could materially adversely affect our future business, operations and financial condition and could cause them to differ materially from the estimates described in forward-looking statements relating to the Company, or its business, property or financial results, each of which could cause purchasers of our securities to lose part or all of their investment:

• the risk factors set out in our 2022 AIF under "Risk Factors";

• the risk factors identified in our 2022 Annual MD&A and our Interim MD&A;

• the risk factors set out in the Base Prospectus under "Risk Factors"; and

• the risk factors set out below.

In addition, you should consider carefully the risk factors and cautionary language included throughout each of the above documents, and in the other documents that we have incorporated into this Prospectus by reference. These risks are not the only risks we face; risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business, financial condition, results of operations and prospects.

Risks Related to the Offering and the Common Shares

No certainty regarding the net proceeds to the Company.

There is no certainty that any Offered Shares will be sold under the Offering or that the full offering amount of US$50,000,000 will be raised under the Offering. The Agents have agreed to use their commercially reasonable efforts to sell, on the Company's behalf, the Offered Shares designated by the Company, but the Company is not required to request the sale of the maximum amount offered or any amount and, if the Company requests a sale, the Agents are not obligated to purchase any Offered Shares that are not sold. As a result of the Offering being made with no minimum amount and only as requested by the Company, the Company may raise substantially less than the maximum total offering amount or nothing at all.

Discretionary use of proceeds.

While information regarding the use of proceeds from the sale of the Offered Shares is described under the heading "Use of Proceeds", we retain broad discretion over the use of the net proceeds from the Offering. The Company has identified certain forward-looking plans and objectives for the proceeds, but the Company's ability to achieve such plans and objectives could change as a result of a number of internal and external factors, such as the impact that continued exploration and evaluation activities may have on the Company's future evaluation and development plans and anticipated costs and timelines, and access to sufficient capital and resources. Because of the number and variability of factors that will determine our use of such proceeds, the Company's ultimate use might vary substantially from its planned use. You may not agree with how the Company allocates or spends the proceeds from the Offering. We may pursue acquisitions, collaborations or other opportunities that do not result in an increase in the market value of our securities, including the market value of our Common Shares, and that may result in or increase our losses from operations.

S-12

To the extent that Taseko applies any of the proceeds from the sale of the Offered Shares to the development of the Florence Copper project, investors are cautioned that Taseko will require additional funds beyond the proceeds from this Offering that are applied to Florence development costs.  Taseko may draw additional funding from the following sources, however no final determination has been made by Taseko regarding the definitive sources of funding and there is no assurance that all funding will be available if and when required: (i) cash from existing operations, (ii) investment commitments under the Mitsui agreement, (iii) equipment financing commitments, and (iv) Taseko's undrawn revolving credit facility. Further, Taseko may determine to access additional sources of financing, such as project debt financing, royalties/metal stream financing and/or additional equity sales, in respect of which no financing commitments have been obtained at present.  To the extent that Taseko raises funds from the Offering with the objective of funding the development of Florence Copper but Taseko does not proceed with the development for any reason, then Taseko will use such funds for general, corporate and administrative expenditures.

The Offered Shares will be sold in "at-the-market" offerings, and investors who buy Offered Shares at different times will likely pay different prices.

Investors who purchase Offered Shares in this Offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. The Company will have discretion, subject to market demand, to vary the timing, prices, and numbers of Offered Shares sold, and there is no minimum or maximum sale price. Investors may experience a decline in the value of their Offered Shares as a result of share sales made at prices lower than the prices they paid.

Future sales may affect the market price of the Common Shares.

In order to finance future operations, the Company will need to raise funds through the issuance of either additional Common Shares or the issuance of debt instruments or other securities which may or may not be convertible into Common Shares.  The Company cannot predict the size of future issuances of Common Shares or the issuance of debt instruments or other securities convertible into Common Shares or the dilutive effect, if any, that future issuances and sales of the Company's securities will have on the market price of the Common Shares.  These sales may have an adverse impact on the market price of the Common Shares.

Our Common Shares are subject to various factors that have made share prices volatile.

The market price of our Common Shares may be subject to large fluctuations, which may not necessarily be related to the financial condition, operating performance, underlying asset values or prospects of Taseko. These factors include macroeconomic developments in North America and globally, market perceptions of the attractiveness of particular industries and volatile trading due to unpredictable general market or trading sentiments. The market price of the Common Shares may be affected by many other variables which are not directly related to our success and are, therefore, not within our control, including other developments that affect the market for all resource sector securities, the breadth of the public market for the Common Shares and the attractiveness of alternative investments.

The market price of the Common Shares is also likely to increase or decrease in response to a number of events and factors, including: our operating performance and the performance of competitors and other similar companies; volatility in commodity prices; the arrival or departure of key personnel; the number of Common Shares to be publicly traded after an offering pursuant to any prospectus supplement; the public's reaction to our press releases, material change reports, other public announcements and our filings with the various securities regulatory authorities; changes in earnings estimates or recommendations by research analysts who track the Common Shares or the shares of other companies in the resource sector; changes in general economic and/or political conditions; acquisitions, strategic alliances or joint ventures involving us or our competitors; and the factors listed under the heading "Cautionary Note Regarding Forward-Looking Statements".

S-13

Multiple listings on the TSX, NYSE American and LSE may lead to an inefficient market in the Company's shares.

Multiple listing of the Common Shares will result in differences in liquidity, settlement and clearing systems, trading currencies, prices and transaction costs between the exchanges where the Common Shares will be quoted. These and other factors may hinder the transferability of the Common Shares between the three exchanges.

The Common Shares are quoted on TSX, NYSE American, and the LSE. Consequently, the trading in and liquidity of the Common Shares will be split between these three exchanges. The price of the Common Shares may fluctuate and may at any time be different on the TSX, the NYSE American and the LSE. This could adversely affect the trading of the Common Shares on these exchanges and increase their price volatility and/or adversely affect the price and liquidity of the Common Shares on these exchanges. The Common Shares are quoted and traded in Canadian Dollars on the TSX, in US Dollars on the NYSE American, and in pounds sterling on the LSE. The market price of the Common Shares on those exchanges may also differ due to exchange rate fluctuations.

No assurance of active or liquid market.

No assurance can be given that an active or liquid trading market for the Common Shares will be sustained. If an active or liquid market for the Common Shares fails to be sustained, the prices at which such shares trade may be adversely affected. Whether or not the Common Shares will trade at lower prices depends on many factors, including the liquidity of the Common Shares, prevailing interest rates and the markets for similar securities, general economic conditions and the Company's financial condition, historic financial performance and future prospects.

There is no assurance that we will pay dividends in the future.

We have not paid any dividends on our Common Shares to date.  Payment of any future dividends, if any, will be at the discretion of our board of directors after taking into account many factors, including our operating results, financial condition, and current and anticipated cash needs.  Accordingly, there is no assurance that we will pay any future dividends on our Common Shares.

We may be a Passive foreign Investment Company for our current taxable year and/or future taxable years which could have adverse U.S. federal income tax consequences for U.S. Holders.

Potential investors in Offered Shares that are U.S. Holders (defined below in "Material United States Federal Income Tax Considerations for U.S. Holders") should be aware that there is a risk that we (i) may be a "passive foreign investment company" (a "PFIC") for the tax year ending December 31, 2023, and (ii) may be a PFIC in subsequent years. If we are a PFIC for any year during a U.S. Holder's holding period, then such U.S. Holder generally will be subject to a special, highly adverse tax regime, including special adverse U.S. tax rules with respect to so-called "excess distributions" received on Offered Shares. Gain realized upon a disposition of Offered Shares (including upon certain dispositions that would otherwise be tax-free) also will be treated as an excess distribution. Excess distributions are punitively taxed and are subject to additional interest charges. Additional special adverse rules also apply to U.S. Holders who own Offered Shares if we are a PFIC and have a non-US subsidiary that is also a PFIC, as could happen with respect to certain subsidiaries of the Company. A U.S. Holder might be able to make an election with respect to Offered Shares to mitigate the adverse tax rules that apply to PFICs, but any such election may accelerate the recognition of taxable income, may result in the recognition of ordinary income and may not eliminate all adverse U.S. consequences that would result from our being a PFIC. See "Material United States Federal Income Tax Considerations for U.S. Holders". Each investor who is a U.S. Holder should consult its own tax advisor regarding the tax consequences of the PFIC rules and the acquisition, ownership, and disposition of the Offered Shares.

CONSOLIDATED CAPITALIZATION

Since December 31, 2022, the date of our financial statements for the most recently completed financial period, there have been no material changes in our consolidated share and debt capital other than as outlined under "Prior Sales". For information on the issuance of Common Shares pursuant to the exercise of stock options, deferred share units ("DSUs") and preferred share units ("PSUs"), see "Prior Sales".

S-14

DESCRIPTION OF SECURITIES

The authorized share capital of the Company consists of an unlimited number of Common Shares without par value, of which 288,471,846 shares were issued and outstanding as at the date of this Prospectus Supplement. The holders of Common Shares are entitled to receive notice of any meeting of the shareholders of the Company and to attend and vote thereat, except those meetings at which only the holders shares of another class or of a particular series are entitled to vote.  Each Common Share entitles its holder to one vote.  The holders of Common Shares are entitled to receive on a pro-rata basis such dividends as the board of directors may declare out of funds legally available therefor.  In the event of the dissolution, liquidation, winding-up or other distribution of our assets, such holders are entitled to receive on a pro-rata basis all of assets of the Company remaining after payment of all of liabilities.  The Common Shares carry no pre-emptive or conversion rights.

USE OF PROCEEDS

The net proceeds of the Offering, if any, are not determinable in light of the nature of the distribution. Sales of Offered Shares, if any, will be made in transactions that are deemed to be "at-the-market distributions" as defined in NI 44-102 and an "at-the-market offering" as defined in Rule 415 under the U.S. Securities Act, including sales made by the Agents directly on the TSX and the NYSE American or any other trading market for the Common Shares in Canada or the United States. The net proceeds of any given distribution of Offered Shares through the Agents in "at-the-market distributions" and an "at-the-market offering" under the Distribution Agreement will represent the gross proceeds of the Offering, after deducting the Commission and the expenses of the Offering. The gross proceeds of the Offering will be up to US$50,000,000. There is no minimum amount of funds that must be raised under the Offering. This means that the Offering may terminate after raising only a portion of the Offering amount set out above, or none at all. See "Plan of Distribution".

The use of proceeds will be used by Taseko for its general corporate purposes, which may include (i) capital expenditures for Gibraltar, (ii) expenses associated with the development of Florence Copper, (iii) expenditures on Taseko's other projects, and (iv) general corporate and working capital purposes.

The main business objectives the Company intends to accomplish using the net proceeds of the Offering, together with the Company's current liquidity sources including cash-flow from operations, are (i) to continue production from Gibraltar, (ii) to develop Florence Copper, subject to receipt of the UIC permit from the EPA, as discussed further in the 2022 AIF, (iii) to advance development work on Taseko's other projects, and (iv) to otherwise to advance the general corporate objectives of Taseko.

Although the Company intends to use the net proceeds from the Offering as set forth above, the actual allocation of the net proceeds may vary from those allocations set out above, depending on the amount of proceeds raised, the time periods in which the proceeds are raised, future developments in relation to the financing and advancement of Florence Copper or other projects or unforeseen events, including those listed under "Risk Factors" of the Prospectus and the 2022 AIF. For example, if only a portion of the net proceeds are raised, such proceeds could all be allocated to general, corporate and administrative expenses and not apportioned as described in the use of proceeds table above. Potential investors are cautioned that notwithstanding the Company's current intentions regarding the use of the net proceeds of the Offering, there may be circumstances where a reallocation of the net proceeds may be advisable for reasons that management believes, in its discretion, are in the Company's best interests.

Qualified Person

Richard Weymark, P. Eng., MBA, Vice President Engineering of the Company, is the qualified person, within the meaning of NI 43-101, who has reviewed and confirmed that the above-noted use of net proceeds allocations are reasonable.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is, as of the date hereof, a general summary of the principal Canadian federal income tax considerations under the Income Tax Act (Canada) (the "Tax Act") and the regulations thereunder (the "Regulations") generally applicable to a holder who acquires Offered Shares as beneficial owner pursuant to this Prospectus Supplement and who, at all relevant times, for the purposes of the Tax Act, deals at arm's length with the Company and the Agents, is not affiliated with the Company or the Agents, and will acquire and hold such Offered Shares as capital property (each, a "Holder"), all within the meaning of the Tax Act. Offered Shares will generally be considered to be capital property to a Holder unless the Holder holds or uses the Offered Shares or is deemed to hold or use the Offered Shares in the course of carrying on a business of trading or dealing in securities or has acquired them or is deemed to have acquired them in a transaction or transactions considered to be an adventure in the nature of trade.

This summary does not apply to (a) a Holder that is a "financial institution" for purposes of the mark-to-market rules contained in the Tax Act; (b)  a Holder an interest in which would constitute a "tax shelter investment" as defined in the Tax Act; (c)  a Holder that is a "specified financial institution" as defined in the Tax Act; (d)  a Holder that is a corporation resident in Canada for the purposes of the Tax Act that is or becomes, or does not deal at arm's length for purposes of the Tax Act with a corporation resident in Canada that is or becomes, as part of a transaction or event or series of transactions or events that includes the acquisition of the Offered Shares, controlled by a non-resident person, or group of non-resident persons not dealing with each other at arm's length, for purposes of the foreign affiliate dumping rules in Section 212.3 of the Tax Act; (e) a Holder that reports its "Canadian tax results", as defined in the Tax Act, in a currency other than Canadian currency; (f)  a Holder that is exempt from tax under the Tax Act; (g) a Holder that receives dividends on the Common Shares under or as part of a "dividend rental arrangement" as defined in the Tax Act; (h) a Holder that has entered into, or will enter into, a "synthetic disposition arrangement" or a "derivative forward agreement" with respect to the Offered Shares, as those terms are defined in the Tax Act; or (i) a Holder that is otherwise of special status or in special circumstances. Such Holders should consult their own tax advisors with respect to an investment in Offered Shares.

This summary does not address the deductibility of interest by a Holder who has borrowed money or otherwise incurred debt in connection with the acquisition of Offered Shares.

This summary is based upon the current provisions of the Tax Act and the Regulations in force as of the date hereof, any specific proposals to amend the Tax Act and the Regulations (the "Tax Proposals") which have been announced by or on behalf the Minister of Finance (Canada) prior to the date hereof, the current provisions of the Canada-United States Tax Convention (1980) (the "Canada-U.S. Tax Convention"), and our understanding of the current published administrative policies and assessing practices of the Canada Revenue Agency (the "CRA"). This summary assumes that the Tax Proposals will be enacted in the form proposed and does not take into account or anticipate any other changes in law, whether by way of judicial, legislative or governmental decision or action, nor does it take into account provincial, territorial or foreign income tax legislation or considerations, which may differ from the Canadian federal income tax considerations discussed herein. No assurances can be given that the Tax Proposals will be enacted as proposed or at all, or that legislative, judicial or administrative changes will not modify or change the statements expressed herein.

This summary is not exhaustive of all possible Canadian federal income tax considerations applicable to an investment in Offered Shares. This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or income tax advice to any particular Holder. Holders should consult their own income tax advisors with respect to the tax consequences applicable to them based on their own particular circumstances.

Currency Conversion

Generally, for purposes of the Tax Act, all amounts relating to the acquisition, holding, or disposition of Offered Shares must be determined in Canadian dollars. Any such amount that is expressed or denominated in a currency other than Canadian dollars must be converted into Canadian dollars using the relevant exchange rate determined in accordance with the Tax Act.

S-18

Residents of Canada

The following portion of this summary is generally applicable to a Holder who, for purposes of the Tax Act, is resident or deemed to be resident in Canada at all relevant times (each, a "Resident Holder"). Certain Resident Holders whose Offered Shares might not otherwise qualify as capital property may be entitled to make an irrevocable election pursuant to subsection 39(4) of the Tax Act to have the Offered Shares, and every other "Canadian security" (as defined by the Tax Act) owned by such Resident Holder in the taxation year of the election and in all subsequent taxation years, deemed to be capital property. Resident Holders should consult their own tax advisors for advice as to whether an election under subsection 39(4) of the Tax Act is available or advisable in their particular circumstances.

Taxation of Dividends

Dividends received or deemed to be received on the Offered Shares will be included in computing a Resident Holder's income. In the case of a Resident Holder who is an individual (including certain trusts), dividends (including deemed dividends) received on the Offered Shares will be included in the Resident Holder's income and be subject to the gross-up and dividend tax credit rules applicable to taxable dividends received by an individual from taxable Canadian corporations, including the enhanced gross-up and dividend tax credit for "eligible dividends", if any, that are properly designated as such by the Company. There may be limitations on the ability of the Company to designate dividends as eligible dividends.

In the case of a Resident Holder that is a corporation, dividends (including deemed dividends) received on the Offered Shares will be included in the Resident Holder's income and will normally be deductible in computing such Resident Holder's taxable income, subject to all restrictions under the Tax Act. In certain circumstances, subsection 55(2) of the Tax Act will treat a taxable dividend received by a Resident Holder that is a corporation as proceeds of disposition or a capital gain. Resident Holders that are corporations should consult their own tax advisors having regard to their own circumstances.

A Resident Holder that is a "private corporation" or "subject corporation" (as such terms are defined in the Tax Act) may be liable to pay a tax (refundable in certain circumstances) under Part IV of the Tax Act on dividends received or deemed to be received on the Offered Shares to the extent that such dividends are deductible in computing the Resident Holder's taxable income for the year.

Dividends received by a Resident Holder who is an individual (including certain trusts) may result in such Resident Holder being liable for minimum tax under the Tax Act. Resident Holders who are individuals should consult their own tax advisors in this regard.

Disposition of Offered Shares

A Resident Holder who disposes of, or is deemed to have disposed of, an Offered Share (other than to the Company, unless purchased by the Company in the open market in the manner in which shares are normally purchased by any member of the public in the open market) will realize a capital gain (or incur a capital loss) equal to the amount by which the proceeds of disposition in respect of the Offered Share exceed (or are exceeded by) the aggregate of the adjusted cost base to the Resident Holder of such Offered Share immediately before the disposition or deemed disposition and any reasonable expenses incurred for the purpose of making the disposition. Generally, the adjusted cost base to a Resident Holder of an Offered Share at any particular time will be determined by averaging the cost of that Offered Share with the adjusted cost base of all other Common Shares held as capital property at that time by the Resident Holder. The tax treatment of capital gains and capital losses is discussed in greater detail below under the subheading "Taxation of Capital Gains and Losses".

Taxation of Capital Gains and Losses

Generally, one-half of any capital gain (a "taxable capital gain") realized by a Resident Holder must be included in the Resident Holder's income for the taxation year in which the disposition occurs. Subject to and in accordance with the provisions of the Tax Act, one-half of any capital loss incurred by a Resident Holder (an "allowable capital loss") must generally be deducted from taxable capital gains realized by the Resident Holder in the taxation year in which the disposition occurs. Allowable capital losses in excess of taxable capital gains for the taxation year of disposition generally may be carried back and deducted in the three preceding taxation years or carried forward and deducted in any subsequent year against taxable capital gains realized in such years, in the circumstances and to the extent provided in the Tax Act.

S-19

A capital loss realized on the disposition of an Offered Share by a Resident Holder that is a corporation may in certain circumstances be reduced by the amount of dividends which have been previously received or deemed to have been received by the Resident Holder on the Offered Share. Similar rules may apply where a corporation is, directly or indirectly through a trust or partnership, a member of a partnership or a beneficiary of a trust that owns Offered Shares. A Resident Holder to which these rules may be relevant is urged to consult its own tax advisor.

A Resident Holder that is throughout the relevant taxation year a "Canadian-controlled private corporation" (as defined in the Tax Act) or a "substantive CCPC" (as proposed to be defined in the Tax Act in Tax Proposals released on August 9, 2022) may be liable to pay an additional tax (refundable in certain circumstances) on its "aggregate investment income" (as defined in the Tax Act) for the year, which is defined to include an amount in respect of taxable capital gains.

Capital gains realized by a resident who is an individual (including certain trusts) may result in such Resident Holder being liable for minimum tax under the Tax Act. Resident Holders who are individuals should consult their own tax advisors in this regard.

Non-Residents of Canada

The following portion of this summary is generally applicable to a Holder who, for purposes of the Tax Act and at all relevant times, is neither resident nor deemed to be resident in Canada and does not use or hold, and will not be deemed to use or hold, Offered Shares in a business carried on in Canada (each, a "Non-Resident Holder"). The term "U.S. Holder," for the purposes of this summary, means a Non-Resident Holder who, for purposes of the Canada-U.S. Tax Convention, is at all relevant times a resident of the United States and is a "qualifying person" within the meaning of the Canada-U.S. Tax Convention eligible for the full benefits of the Canada-U.S. Tax Convention. In some circumstances, persons deriving amounts through fiscally transparent entities (including limited liability companies) may be entitled to benefits under the Canada-U.S. Tax Convention. U.S. Holders are urged to consult their own tax advisors to determine their entitlement to benefits under the Canada-U.S. Tax Convention and related compliance requirements based on their particular circumstances.

Special considerations, which are not discussed in this summary, may apply to a Non-Resident Holder that is an insurer that carries on an insurance business in Canada and elsewhere or an authorized foreign bank (as defined in the Tax Act). Such Non-Resident Holders should consult their own advisors.

Taxation of Dividends

Subject to an applicable tax treaty or convention, dividends paid or credited, or deemed to be paid or credited, to a Non-Resident Holder on the Offered Shares will be subject to Canadian withholding tax under the Tax Act at the rate of 25% of the gross amount of the dividend. Such rate is generally reduced under the Canada-U.S. Tax Convention to 15% if the beneficial owner of such dividend is a U.S. Holder. The rate of withholding tax is generally further reduced to 5% if the beneficial owner of such dividend is a U.S. Holder that is a company that owns, directly or indirectly, at least 10% of the voting stock of the Company. Non-Resident Holders should consult their own tax advisors to determine their entitlement to benefits under any applicable tax treaty or convention based on their particular circumstances.

Disposition of Offered Shares

A Non-Resident Holder will not be subject to tax under the Tax Act in respect of any capital gain realized by such Non-Resident Holder on a disposition of Offered Shares, unless the Offered Shares constitute "taxable Canadian property" (as defined in the Tax Act) of the Non-Resident Holder at the time of the disposition and are not "treaty-protected property" (as defined in the Tax Act) of the Non-Resident Holder at the time of the disposition.

Generally, as long as the Offered Shares are listed on a designated stock exchange (which currently includes the TSX) at the time of their disposition by a Non-Resident Holder, the Offered Shares will not constitute taxable Canadian property of such Non-Resident Holder unless, at any time during the 60-month period immediately preceding the disposition, the following two conditions are met concurrently: (a) the Non-Resident Holder, persons with which the Non-Resident Holder does not deal at arm's length, partnerships whose members include, either directly or indirectly through one or more partnerships, the Non-Resident Holder and/or persons which do not deal at arm's length with the Non-Resident Holder, or any combination of the foregoing, owned 25% or more of the issued shares of any class or series of shares of the capital stock of the Company, and (b) more than 50% of the fair market value of the Offered Shares was derived directly or indirectly, from one or any combination of real or immovable property situated in Canada, "Canadian resource properties", "timber resource properties" (each as defined in the Tax Act), and options in respect of or interests in, or for civil law rights in, any such property (whether or not such property exists).  Notwithstanding the foregoing, Offered Shares may also be deemed to be "taxable Canadian property" of a Non-Resident Holder in other circumstances under the Tax Act.

S-20

The Offered Shares of a U.S. Holder will generally constitute "treaty-protected property" for purposes of the Tax Act unless the value of the Offered Shares is derived principally from real property situated in Canada. For this purpose, "real property" has the meaning that term has under the laws of Canada and includes any option or similar right in respect thereof and in any case, includes usufruct of real property, rights to explore for or to exploit mineral deposits, sources and other natural resources and rights to amounts computed by reference to the amount or value of production from such resources.

If Offered Shares are taxable Canadian property of a Non-Resident Holder and are not treaty-protected property of the Non-Resident Holder at the time of their disposition, the consequences above under "Residents of Canada - Disposition of Offered Shares" and "Residents of Canada - Taxation of Capital Gains and Losses" will generally apply.

Non-Resident Holders whose Offered Shares may constitute taxable Canadian property should consult their own advisors.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR U.S. HOLDERS

Subject to the limitations and qualifications stated herein, this discussion sets forth material U.S. federal income tax considerations relating to the acquisition, ownership and disposition by U.S. Holders (as hereinafter defined) of the Offered Shares. The discussion is based on the Internal Revenue Code of 1986, as amended (the "Code"), its legislative history, Treasury regulations thereunder (whether final, temporary or proposed), published rulings and court decisions, and the Canada-U.S. Tax Convention, all as currently in effect and all subject to change at any time, possibly with retroactive effect. This summary applies only to U.S. Holders. This discussion of a U.S. Holder's tax consequences addresses only those persons that acquire Offered Shares in the Offering pursuant to this Prospectus Supplement and that hold those Offered Shares as capital assets (generally, property held for investment). This summary also does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis, or the tax consequences of transactions effected prior or subsequent to, or concurrently with, the acquisition of any Offered Shares. We have not and will not seek any rulings from the Internal Revenue Service ("IRS") regarding the matters discussed below, and there can be no assurance that the IRS will not take positions concerning the tax consequences of the acquisition, ownership or disposition of Offered Shares that are different from those discussed below.

This summary provides only a general discussion and is not a complete analysis of all potential tax consequences arising from an investment in the Offered Shares. In addition, it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder's particular circumstances, including non-U.S. tax consequences, state and local tax consequences, estate and gift tax consequences, alternative minimum tax consequences, and tax consequences applicable to U.S. Holders subject to special rules, such as:

• banks, insurance companies, and certain other financial institutions;

• U.S. expatriates and certain former citizens or long-term residents of the United States;

• persons holding Offered Shares as part of a hedging transaction, "straddle," wash sale, conversion transaction or integrated transaction or persons entering into a constructive sale with respect to Offered Shares;

• persons whose "functional currency" for U.S. federal income tax purposes is not the U.S. dollar;

• brokers, dealers or traders in securities, commodities or currencies;

• tax-exempt entities, qualified retirement plans, individual retirement accounts, other tax-deferred accounts or government organizations;

S-21

• S corporations, partnerships, or other entities or arrangements classified as partnerships or otherwise treated as pass-through entities for U.S. federal income tax purposes;

• regulated investment companies or real estate investment trusts;

• persons who acquired the Offered Shares pursuant to the exercise of any employee stock option or otherwise as compensation;

• persons required to accelerate the recognition of any item of gross income with respect to the Offered Shares as a result of such income being recognized on an applicable financial statement;

• persons holding the Offered Shares in connection with a trade or business, permanent establishment, or fixed base outside the United States; and

• persons who own (directly or through attribution) 10% or more (by vote or value) of our outstanding Common Shares.

If an entity or arrangement that is classified as a partnership (or other pass-through entity) for U.S. federal income tax purposes holds Offered Shares, the U.S. federal income tax treatment of an owner of such entity will generally depend on the status of the owner and the activities of the entity. Any entity treated as a partnership (or other pass-through entity) and owners in of such entities are encouraged to consult their own tax advisors as to the particular U.S. federal income tax consequences of acquiring, holding and disposing of Offered Shares.

For the purposes of this summary, a "U.S. Holder" is a holder who, for U.S. federal income tax purposes, is a beneficial owner of Offered Shares and is:

• An individual who is a citizen or resident of the United States;

• a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia;

• an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust if (1) a U.S. court is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have authority to control all substantial decisions of the trust or (2) the trust has a valid election in effect to be treated as a U.S. person under applicable Treasury regulations.

PERSONS CONSIDERING AN INVESTMENT IN OFFERED SHARES SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES APPLICABLE TO THEM RELATING TO THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE OFFERED SHARES, INCLUDING THE APPLICATION OF U.S. FEDERAL, STATE, LOCAL AND NON-U.S. TAX LAWS.

Passive Foreign Investment Company Rules

If we are classified as a passive foreign investment company ("PFIC") in any taxable year, a U.S. Holder will be subject to special rules generally intended to reduce or eliminate any benefits from the deferral of U.S. federal income tax that a U.S. Holder could derive from investing in a non-U.S. corporation that does not distribute all of its earnings on a current basis.

A non-U.S. corporation will be classified as a PFIC for any taxable year in which, after applying certain look-through rules, either:

• at least 75% of its gross income is passive income (such as interest income); or

• at least 50% of its gross assets (determined on the basis of a quarterly average) is attributable to assets that produce passive income or are held for the production of passive income.

We will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other corporation, the equity of which we own, directly or indirectly, 25% or more (by value). We will also be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any partnership, the equity of which we own, directly or indirectly, 25% or more by value (a "look-through partnership"). In addition, if we own, directly or indirectly, less than 25% (by value) of the equity of a an entity classified as a partnership for U.S. federal income tax purposes, our proportionate share of the income of the partnership will be treated as passive income, and the partnership interest will be treated as a passive asset, except that, in the event that we satisfy an "active partner" test, we may treat less-than-25% owned partnerships as look-through partnerships, unless we elect otherwise.

S-22

The determination of PFIC status is inherently factual, is subject to a number of uncertainties, and can be determined only annually after the close of the tax year in question. Additionally, the analysis depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. There can be no assurance that the Company will or will not be determined to be a PFIC for the current tax year or any prior or future tax year, and no opinion of legal counsel or ruling from the IRS concerning the status of the Company as a PFIC has been obtained or will be requested. U.S. Holders should consult their own tax advisors regarding the PFIC status of the Company.

If we are classified as a PFIC in any year that a U.S. Holder owns any Common Shares, we will continue to be treated as a PFIC with respect to such U.S. Holder in all succeeding years during which the U.S. Holder owns any Common Shares, regardless of whether we continue to meet the tests described above unless (i) we cease to be a PFIC and the U.S. Holder has made a "deemed sale" election under the PFIC rules or (ii) the U.S. Holder either (x) makes a Qualified Electing Fund Election (a "QEF Election") for all taxable years during such U.S. Holder's holding period in which we are a PFIC, or (y) our Common Shares qualify as "marketable" and the U.S. Holder makes a "mark-to-market" election for all taxable years during such U.S. Holder's holding period in which we are a PFIC (a U.S. Holder who does not make either election described in this clause (ii), a "Non-Electing U.S. Holder"). If the "deemed sale" election is made, a U.S. Holder will be deemed to have sold such U.S. Holder's Common Shares at their fair market value and any gain from such deemed sale would be subject to the "excess distribution" rules described below. After the deemed sale election, so long as we do not become a PFIC in a subsequent taxable year, the U.S. Holder's Common Shares with respect to which such election was made will not be treated as shares in a PFIC and the U.S. Holder will not be subject to the rules described below with respect to any "excess distribution" the U.S. Holder receives from us or any gain from an actual sale or other disposition of the Common Shares. U.S. Holders should consult their tax advisors as to the possibility and consequences of making a deemed sale election if such election becomes available.

For each taxable year we are treated as a PFIC, a U.S. Holder who is a Non-Electing U.S. Holder will be subject to special tax rules for any “excess distribution” such U.S. Holder receives and any gain such U.S. Holder recognizes from a sale or other disposition (including, under certain circumstances, a pledge) of Offered Shares. Absent the making of a QEF Election or a mark-to-market election, distributions received by a Non-Electing U.S. Holder in a taxable year that are greater than 125% of the average annual distributions a U.S. Holder received during the shorter of the three preceding taxable years or the U.S. Holder’s holding period for the Offered Shares will be treated as an excess distribution. Under these special tax rules:

• the excess distribution or gain will be allocated ratably over a U.S. Holder's holding period for the Offered Shares;

• the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we became a PFIC, will be treated as ordinary income; and

• the amount allocated to each other year will be subject to the highest tax rate in effect for that year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

The tax liability for amounts allocated to years prior to the year of disposition or excess distribution cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the Offered Shares cannot be treated as capital, even if a U.S. Holder holds the Offered Shares as capital assets. Special rules will limit the foreign tax credits that a U.S. Holder may claim on distributions received from us if we are a PFIC.

In addition, if we are a PFIC, a U.S. Holder (including a U.S. Holder that is not a Non-Electing U.S. Holder) will generally be subject to similar rules with respect to distributions that we receive from, and our dispositions of the stock of, any of our direct or indirect subsidiaries that also are PFICs (any such subsidiary, a “lower-tier PFIC”), as if such distributions were indirectly received by, and/or dispositions were indirectly carried out by, such U.S. Holder. U.S. Holders should consult their tax advisors regarding the application of the PFIC rules to our subsidiaries.

If a U.S. Holder makes an effective QEF Election, the U.S. Holder will be required to include in gross income each year, whether or not we make distributions, as capital gains, such U.S. Holder's pro rata share of our net capital gains and, as ordinary income, such U.S. Holder's pro rata share of our earnings in excess of our net capital gains. Currently, we do not expect that we would provide the information necessary for U.S. Holders to make a QEF Election if we determine that we are a PFIC. Thus, prospective investors should assume that a QEF Election will not be available.

S-23

Certain adverse rules will apply to a U.S. Holder if we are a PFIC whether or not the U.S. Holder makes a QEF Election.  For example, a U.S. Holder that pledges Offered Shares as security for a loan will be treated as making a taxable disposition of the Offered Shares if we are a PFIC, except as may be provided in Treasury Regulations.  In addition, a U.S. Holder who acquires Offered Shares from a decedent will not receive an increase in tax basis of the Offered Shares if we are a PFIC. Under Proposed Treasury Regulations, which if finalized as proposed would be retroactively effective, a U.S. Holder that has not made a timely QEF election would be required to recognize gain (but could not recognize loss) on certain transfers of Offered Shares that would otherwise be tax-deferred, such as exchanges pursuant to corporate reorganizations or gifts.

U.S. Holders may make a mark-to-market election with respect to the Offered Shares if we are a PFIC in order to avoid the tax rules applicable to excess distributions made by a PFIC, provided that the Offered Shares are "marketable." Offered Shares will be marketable if they are "regularly traded" on certain U.S. stock exchanges or on a foreign stock exchange that meets certain conditions. For these purposes, the Offered Shares will be considered regularly traded in any calendar year during which they are traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Any trades, the principal purpose of which is to meet this requirement, will be disregarded. The Offered Shares are listed on the NYSE American, which is a qualified exchange for these purposes. Consequently, if the Offered Shares remain listed on the NYSE American and are regularly traded, we expect that the mark-to-market election would be available to U.S. Holders if we are a PFIC. Each U.S. Holder should consult its own tax advisor as to whether a mark-to-market election is available or advisable with respect to the Offered Shares.

A U.S. Holder that makes a mark-to-market election must include in ordinary income for each year that the Company is a PFIC an amount equal to the excess, if any, of the fair market value of the Offered Shares at the close of the taxable year over the U.S. Holder's adjusted tax basis in the Offered Shares. An electing U.S. Holder may also claim an ordinary loss deduction for the excess, if any, of the U.S. Holder's adjusted basis in the Offered Shares over the fair market value of the Offered Shares at the close of the taxable year, but this deduction is allowable only to the extent of any net aggregate mark-to-market gains for prior years. Gains from an actual sale or other disposition of the Offered Shares will be treated as ordinary income, and any losses incurred on a sale or other disposition of the shares will be treated as an ordinary loss to the extent of any net aggregate mark-to-market gains for prior years. Any loss in excess thereof will be taxed as a capital loss, and capital losses are subject to significant limitations under the Code. Once made, the election cannot be revoked without the consent of the IRS unless the Offered Shares cease to be marketable.

However, a mark-to-market election generally cannot be made for equity interests in any lower-tier PFICs that we own, unless shares of such lower-tier PFIC are themselves "marketable." As a result, even if a U.S. Holder validly makes a mark-to-market election with respect to the Offered Shares, the U.S. Holder may continue to be subject to the PFIC rules (described above) with respect to the U.S. Holder's indirect interest in any of our investments that are treated as an equity interest in a PFIC. U.S. Holders should consult their tax advisors to determine whether any of these elections would be available and if so, what the tax consequences of the alternative treatments would be in their particular circumstances.

A U.S. Holder that owns shares in a PFIC during any taxable year of the U.S. Holder may have to file an IRS Form 8621 (whether or not a QEF Election or mark-to-market election is made) and such other information as may be required by the U.S. Treasury Department ("U.S. Treasury"). Failure to do so, if required, will extend the statute of limitations until three years after such required information is furnished to the IRS. Each U.S. Holder should consult its own tax advisor regarding the requirements of filing such information returns under these rules.

WE STRONGLY URGE YOU TO CONSULT YOUR TAX ADVISOR REGARDING THE IMPACT OF OUR PFIC STATUS ON YOUR INVESTMENT IN THE OFFERED SHARES AS WELL AS THE APPLICATION OF THE PFIC RULES TO YOUR INVESTMENT IN THE OFFERED SHARES.

Cash Dividends and Other Distributions

Subject to the discussion under the heading “Passive Foreign Investment Company Rules” above, to the extent there are any distributions made with respect to the Offered Shares, a U.S. Holder generally will be required to include such distributions in its gross income (including the amount of Canadian taxes withheld, if any) as dividend income, but only to the extent that the distribution is paid out of our current or accumulated earnings and profits (computed using U.S. federal income tax principles). The amount of the distribution in excess of our current or accumulated earnings and profits is treated first as a non-taxable return of capital to the extent of the U.S. Holder’s adjusted tax basis in its Offered Shares and, thereafter, as capital gain recognized on a sale or exchange on the day actually or constructively received by the U.S. Holder (as described below under the heading “Sale or Disposition of Offered Shares”). There can be no assurance that we will maintain calculations of our earnings and profits in accordance with U.S. federal income tax principles. U.S. Holders should therefore assume that any distribution with respect to the Offered Shares will constitute dividend income. Dividends paid on the Offered Shares will not be eligible for the dividends received deduction allowed for distributions from U.S. corporations. 

S-24

Dividends paid to a non-corporate U.S. Holder by a “qualified foreign corporation” may be classified as “qualified dividends” which are subject to reduced rates of taxation if certain holding period and other requirements are met. A qualified foreign corporation generally includes a foreign corporation if (i) the stock with respect to which the dividends are paid is readily tradable on an established securities market in the United States or it is eligible for benefits under a comprehensive U.S. income tax treaty that includes an exchange of information provision and that the U.S. Treasury has determined is satisfactory for these purposes and (ii) it is not a PFIC (as discussed above) for either the taxable year in which the dividend is paid or the preceding taxable year. The Offered Shares are readily tradable on an established securities market, the NYSE American. We may also be eligible for the benefits of the Canada-U.S. Tax Convention. Accordingly, subject to the PFIC rules discussed above, if we are not a PFIC for the year  we pay a dividend or the preceding year, we expect that a non-corporate U.S. Holder should qualify for the reduced tax rate on dividends so long as the applicable holding period requirements are met. U.S. Holders should consult their own tax advisors regarding the availability of the reduced tax rate on dividends in light of their particular circumstances.

Distributions paid in a currency other than U.S. dollars will be included in a U.S. Holder's gross income in a U.S. dollar amount based on the spot exchange rate in effect on the date of actual or constructive receipt, whether or not the payment is converted into U.S. dollars at that time. The U.S. Holder will have a tax basis in such currency equal to such U.S. dollar amount, and any gain or loss recognized upon a subsequent sale or conversion of the foreign currency for a different U.S. dollar amount will generally be U.S. source ordinary income or loss.

If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder generally should not be required to recognize foreign currency gain or loss in respect of the dividend income.

If a U.S. Holder is subject to Canadian withholding taxes (at the rate applicable to such U.S. Holder) with respect to dividends paid on the Offered Shares, such U.S. Holder may be entitled to receive either a deduction or a foreign tax credit for such Canadian taxes paid. Complex limitations apply to the foreign tax credit. Dividends paid by us generally will constitute foreign source income and generally will be categorized as "passive category income" or in certain circumstances "general category income." Because the foreign tax credit rules are complex, each U.S. Holder should consult its own tax advisor regarding the foreign tax credit rules..

Sale or Disposition of Offered Shares

Subject to the discussion under the heading "Passive Foreign Investment Company Rules" above, a U.S. Holder generally will recognize gain or loss on the taxable sale or exchange of the Offered Shares in an amount equal to the difference between the U.S. dollar amount realized on such sale or exchange (determined in the case of the Offered Shares sold or exchanged for currencies other than U.S. dollars by reference to the spot exchange rate in effect on the date of the sale or exchange or, if the Offered Shares sold or exchanged are traded on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, which election must be applied consistently from year to year and cannot be changed without the consent of the IRS, the spot exchange rate in effect on the settlement date) and the U.S. Holder's adjusted tax basis in the Offered Shares determined in U.S. dollars. The initial tax basis of the Offered Shares to a U.S. Holder will be the U.S. Holder's U.S. dollar purchase price for the Offered Shares (determined by reference to the spot exchange rate in effect on the date of the purchase, or if the Offered Shares purchased are traded on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, which election must be applied consistently from year to year and cannot be changed without the consent of the IRS, the spot exchange rate in effect on the settlement date). An accrual basis U.S. Holder that does not make the special election will recognize exchange gain or loss to the extent attributable to the difference between the exchange rates on the sale date and the settlement date, and such exchange gain or loss generally will constitute ordinary income or loss.

S-25

Subject to the discussion under the heading "Passive Foreign Investment Company Rules" above, such gain or loss will be capital gain or loss and will be long-term gain or loss if the Offered Shares have been held for more than one year. Under current law, long-term capital gains of non-corporate U.S. Holders generally are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations under the Code. Capital gain or loss, if any, recognized by a U.S. Holder generally will be treated as U.S. source income or loss for U.S. foreign tax credit purposes. U.S. Holders are encouraged to consult their own tax advisors regarding the availability of the U.S. foreign tax credit in their particular circumstances.

Medicare Contribution Tax

Certain U.S. Holders that are individuals, estates or certain trusts, and whose incomes exceed certain thresholds, must pay a 3.8% tax, or Medicare surtax, on their "net investment income." Net investment income generally includes, among other things, dividend income and net gains from the disposition of stock. A U.S. Holder that is an individual, estate or trust should consult its own tax advisor regarding the applicability of the Medicare contribution tax to its income and gains in respect of its investment in the Offered Shares.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding currently at a 24% tax rate, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding on a duly executed IRS Form W-9 or otherwise establishes an exemption.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder's U.S. federal income tax liability and may entitle the U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Certain Reporting Requirements

U.S. Holders paying more than $100,000 for the Offered Shares generally may be required to file IRS Form 926 reporting the payment of the offer price for the Offered Shares. Substantial penalties may be imposed upon a U.S. Holder that fails to comply. Each U.S. Holder should consult its own tax advisor as to the possible obligation to file IRS Form 926.

Information with Respect to Foreign Financial Assets

Certain U.S. Holders who are individuals (and, under regulations, certain entities) may be required to report information relating to the Offered Shares, subject to certain exceptions (including an exception for Offered Shares held in accounts maintained by certain U.S. financial institutions), by filing IRS Form 8938 (Statement of Specified Foreign Financial Assets) with their federal income tax returns. Such U.S. Holders who fail to timely furnish the required information may be subject to a penalty. Additionally, if a U.S. Holder does not file the required information, the statute of limitations with respect to tax returns of the U.S. Holder to which the information relates may not close until three years after such information is filed.

U.S. Holders should consult their own tax advisors regarding their reporting obligations with respect to their acquisition, ownership and disposition of Offered Shares and the application of the U.S. information reporting and withholding rules.

PLAN OF DISTRIBUTION

The Company has entered into the Distribution Agreement with the Agents under which the Company may issue and sell from time to time Offered Shares having an aggregate sale price of up to US$50,000,000 (or the equivalent in Canadian dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold) in each of the provinces and territories of Canada and in the United States pursuant to placement notices delivered by the Company to the Agents from time to time in accordance with the terms of the Distribution Agreement. The Distribution Agreement is filed with the SEC and incorporated by reference into the U.S. Registration Statement of which this Prospectus Supplement forms a part. Sales of Offered Shares, if any, will be made in transactions that are deemed to be “at-the-market distributions” as defined in NI 44-102 and an “at-the-market offering” as defined in Rule 415 under the U.S. Securities Act, including sales made by the Agents directly on the TSX, the NYSE American or any other trading market for the Common Shares in Canada or the United States. Subject to the pricing parameters in a placement notice, the Offered Shares will be distributed at the market prices prevailing at the time of the sale, or as otherwise agreed upon by the Company and applicable agent. As a result, prices may vary as between purchasers and during the period of distribution. The Company cannot predict the number of Offered Shares that it may sell under the Distribution Agreement on the TSX, the NYSE American or any other trading market for the Common Shares in Canada or the United States, or if any Offered Shares will be sold.

S-26

The Agents will offer the Offered Shares subject to the terms and conditions of the Distribution Agreement from time to time as agreed upon by the Company and the Agents. The Company will designate the maximum amount or value of Offered Shares, along with the minimum price per Offered Share, to be sold pursuant to any single placement instruction to an Agent, determined in the sole discretion of the Company (the "Designated Agent"). Subject to the terms and conditions of the Distribution Agreement, the Designated Agent will, severally and not jointly, use its commercially reasonable efforts to sell on the Company's behalf all of the Offered Shares requested to be sold by the Company, consistent with their normal sales and trading practices.

Either the Company or the Designated Agent may suspend the Offering of the Offered Shares being made through the Agents under the Distribution Agreement upon proper notice to the other party, provided that such suspension or termination shall not affect or impair the parties' respective obligations with respect to the Offered Shares sold under the Equity Distribution Agreement prior to the giving of such notice. The Company has the right, by giving written notice as specified in the Distribution Agreement, to terminate the Distribution Agreement in its sole discretion at any time. Each of the Agents has the right, by giving written notice as specified in the Distribution Agreement, to terminate the Distribution Agreement in its sole discretion with respect to itself, but not with respect to any other Agent, at any time. The Offering pursuant to the Distribution Agreement will terminate upon the earlier of (i) the issuance and sale of all of the Offered Shares subject to the Distribution Agreement, (ii) May 26, 2025, and (iii) the termination of the Distribution Agreement as permitted therein.

The Company will pay the Agents the Commission for their services in acting as agents in connection with the sale of Offered Shares pursuant to the terms of the Distribution Agreement. The amount of the Commission will be up to 3% of the gross sales price per Offered Share sold. The Commission will be paid in the same currency as the sale of the Offered Shares to which such Commission pertains.

The applicable Agent or Agents will provide written confirmation to the Company following the close of trading on the TSX and the NYSE American each day on which such Agent has made sales of the Offered Shares under the Distribution Agreement, setting forth (i) the number of Offered Shares and the average price of Offered Shares sold on such day (including the number of Offered Shares sold on the TSX, on the NYSE American or on any other marketplace), (ii)  the gross proceeds, (iii) the Commission payable by the Company to the Agents with respect to such sales, and (iv) the net proceeds payable to the Company.

The Company will disclose the number and average price of the Offered Shares sold under this Prospectus Supplement, as well as the gross proceeds, Commission and net proceeds from sales hereunder in its annual and interim financial statements or associated management's discussion and analysis filed on SEDAR and EDGAR, for any quarters in which sales of Offered Shares occur.

Settlement for sales of Offered Shares will occur on the second trading day on the applicable exchange following the date on which any sales were made in return for payment of the net proceeds to the Company. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. Sales of Offered Shares in the United States will be settled through the facilities of the Depositary Trust Corporation or by such other means as the Company and the Agents may agree upon and sales of Offered Shares in Canada will be settled through the facilities of the Canadian Depositary for Securities or by such other means as the Company and the Agents may agree.

If either the Company or the applicable Agent has reason to believe that the Offered Shares are no longer "actively-traded securities" as defined under Rule 101(c)(l) of Regulation M under the Exchange Act, that party will promptly notify the other and sales of the Offered Shares pursuant to the Equity Distribution Agreement will be suspended until that or other exemptive provisions have been satisfied in the judgment of each party to the Distribution Agreement.

S-27

The Canadian Agents will only sell Offered Shares on marketplaces in Canada and the U.S. Agents will only sell Offered Shares on marketplaces in the United States.

In connection with the sales of the Offered Shares on the Company's behalf, the Agents may be deemed to be an "underwriter" within the meaning of the U.S. Securities Act, and the compensation paid to the Agents may be deemed to be underwriting commissions or discounts. The Company has agreed in the Distribution Agreement to provide indemnification and contribution to the Agents against certain liabilities, including liabilities under the U.S. Securities Act. In addition, the Company has agreed, under certain circumstances, to reimburse the reasonable expenses of the Agents in connection with the Offering, pursuant to the terms of the Distribution Agreement.

No Agent and no person or company acting jointly or in concert with an Agent, may, in connection with the distribution, enter into any transaction that is intended to stabilize or maintain the market price of the securities or securities of the same class as the securities distributed under this Prospectus Supplement, including selling an aggregate number or principal amount of securities that would result in the Agents creating an over-allocation position in the securities.

The total expenses related to the Offering payable by the Company, excluding the Commission payable to the Agents under the Distribution Agreement, are estimated to be approximately US$500,000.

Each of the Agents and its affiliates have in the past provided and may in the future provide various investment banking, commercial banking and other financial services for the Company and its affiliates, for which services they have received and may in the future receive customary fees. To the extent required by Regulation M, the Agents will not engage in any market making activities involving the Common Shares while the Offering is ongoing under this Prospectus Supplement.

Taseko has applied to list the Offered Shares distributed hereunder on the TSX and NYSE American. Listing will be subject to Taseko fulfilling all listing requirements of the TSX and NYSE American. The Offered Shares will also be admitted to trading on the LSE.

Other than in Canada and the United States, no action has been taken by the Company that would permit a public offering of the Offered Shares in any jurisdiction outside Canada or the United States where action for that purpose is required. The Offered Shares may not be offered or sold, directly or indirectly, nor may this Prospectus Supplement or any other offering material or advertisements in connection with the offer and sale of any such Offered Shares be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this Prospectus Supplement comes are advised to inform themselves about and to observe any restrictions relating to the Offering and the distribution of this Prospectus Supplement. This Prospectus Supplement does not constitute an offer to sell or a solicitation of an offer to buy any Offered Shares in any jurisdiction in which such an offer or a solicitation is unlawful.

Conflict of Interest

An affiliate of NBF, NBC, is the lender to the Company under the Credit Facility. Consequently, the Company may be considered to be a "connected issuer", as defined in National Instrument 33-105 -Underwriting Conflicts of the Underwriter, to NBF under applicable securities laws in certain Canadian provinces and territories.

As at December 31, 2022, the Company had drawn $Nil of the US$50 million available under the Credit Facility. As of the date of this Prospectus Supplement, the Company is in compliance with all material terms of the agreements governing the Credit Facility and NBC has not waived any breach by the Company thereunder since the execution of the Credit Facility.

On February 1, 2023, the Company entered into an agreement to extend the maturity date of the Credit Facility by an additional year to July 2, 2026. The Credit Facility matures in July 2026 but contains a springing maturity provision which advances its maturity date forward if the Company's 2026 7.0% Senior Secured Notes have not been refinanced by six months before their maturity date or August 2025.

In addition to the one-year extension of the Credit Facility, the lender agreed to an accordion feature, which allows the amount of the Credit Facility to be increased by US$30 million, for a total of US$80 million, subject to credit approval and other conditions.

S-28

The decision to distribute the Offered Shares offered hereunder and the determination of the terms of the distribution were made through arm's length negotiations between the Company and NBF. NBC did not have any involvement in such decision or determination. NBF and its affiliates will not receive any direct benefit from the Offering other than receipt of the Commission.

As a consequence of the Offering, NBF will receive the Commission in accordance with the terms of the Distribution Agreement.

TRANSFER AGENT AND REGISTRAR

The Company's transfer agent and registrar is Computershare Investor Services Inc., located at 510 Burrard Street, 2^nd Floor, Vancouver, British Columbia V6C 3B9.

ENFORCEABILITY OF CIVIL LIABILITIES

The Company is a corporation existing under the Business Corporations Act (British Columbia).  All but two of our directors, all of our officers, and all of the experts named in the Prospectus, are residents of Canada or otherwise reside outside the United States, and all or a substantial portion of their assets, and a majority of our assets, are located outside the United States.  We have appointed an agent for service of process in the United States, but it may be difficult for holders of the Offered Shares who reside in the United States to effect service within the United States upon those directors, officers and experts who are not residents of the United States.  It may also be difficult for holders of the Offered Shares who reside in the United States to realize upon judgments of courts of the United States predicated upon the Company’s civil liability and the civil liability of its directors, officers and experts under the United States federal securities laws.

We have been advised by our Canadian legal counsel, McMillan LLP, that a judgment of a United States court predicated solely upon civil liability under United States federal securities laws would probably be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes.  We have also been advised by McMillan LLP, however, that there is substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon United States federal securities laws.

We have filed with the SEC, concurrently with our registration statement on Form F-10, an appointment of agent for service of process on Form F-X. Under the Form F-X, we appointed our subsidiary Florence Copper LLC as our agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against or involving the Company in a United States court arising out of, related to, or concerning the offering of the Offered Shares under this Prospectus Supplement.

S-30

This short form prospectus is a base shelf prospectus.  This short form base shelf prospectus has been filed under legislation in all the provinces and territories of Canada that permit certain information about these securities to be determined after the short form base shelf prospectus has become final and that permit the omission of that information from this prospectus.  The legislation requires the delivery to purchasers of a prospectus supplement containing the omitted information within a specified period of time after agreeing to purchase any of these securities, except in cases where an exemption from such delivery requirements is available or has been obtained.

No securities regulatory authority has expressed an opinion about these securities and it is an offence to claim otherwise. This short form base shelf prospectus constitutes a public offering of these securities only in those jurisdictions where they may be lawfully offered for sale and therein only by persons permitted to sell such securities.

Information has been incorporated by reference in this prospectus from documents filed with the securities commissions or similar authorities in Canada.  Copies of the documents incorporated herein by reference may be obtained on request without charge from Taseko Mines Limited, 12^th Floor, 1040 West Georgia Street, Vancouver, British Columbia, V6E 4H1 (Telephone 778-373-4533) (Attn: the Corporate Secretary), and are also available electronically at www.sedar.com.

SHORT FORM BASE SHELF PROSPECTUS

New Issue April 25, 2023

US$600,000,000

Common Shares
Warrants
Subscription Receipts
Debt Securities

Units

This short form base shelf prospectus (the "Prospectus") relates to the offering for sale of common shares (the "Common Shares"), warrants (the "Warrants"), subscription receipts (the "Subscription Receipts"), debt securities (the "Debt Securities"), or any combination of such securities (the "Units") (all of the foregoing, collectively, the "Securities") by Taseko Mines Limited (the "Company" or "Taseko") from time to time, during the 25-month period that the Prospectus, including any amendments hereto, remains effective, in one or more series or issuances, with a total offering price of the Securities in the aggregate, of up to US$600,000,000. The Securities may be offered in amounts at prices to be determined based on market conditions at the time of the sale and set forth in an accompanying prospectus supplement (a "Prospectus Supplement").  In addition, Securities may be offered and issued in consideration for the acquisition of other businesses, assets or securities by the Company or a subsidiary of the Company.  The consideration for any such acquisition may consist of any of the Securities separately, a combination of Securities or any combination of, among other things, Securities, cash and assumption of liabilities.

The Company’s outstanding Common Shares are listed for trading on the Toronto Stock Exchange (the “TSX”) under the trading symbol “TKO”, on the NYSE American (the “NYSE American”) under the trading symbol “TGB”, and on the London Stock Exchange (the “LSE”) under the trading symbol “TKO”.  The closing price of the Company’s Common Shares on the TSX, NYSE American, and the LSE on April 24, 2023, being the trading session on the last trading day before the date of the Prospectus, was $2.31 per Common Share, US$1.69 per Common Share and GB£1.33 per Common Share, respectively.

This offering is made by a Canadian issuer that is permitted, under a multijurisdictional disclosure system adopted by the United States and Canada (the "MJDS"), to prepare this Prospectus in accordance with Canadian disclosure requirements.  Prospective investors should be aware that such requirements are different from those of the United States.  Financial statements included or incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB") and may not be comparable to financial statements of United States companies.  Our financial statements are subject to audit in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB") and our auditor is subject to both Canadian auditor independence standards and the auditor independence standards of the PCAOB and the United States Securities and Exchange Commission ("SEC").

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Company is incorporated under the laws of British Columbia, Canada, that the majority of its officers and directors are residents of Canada, that all of the experts named in the registration statement are not residents of the United States, and that a substantial portion of the assets of the Company and said persons are located outside the United States.

Investing in Securities of the Company involves a high degree of risk.  You should carefully review the risks outlined in this Prospectus (together with any Prospectus Supplement) and in the documents incorporated by reference in this Prospectus and any Prospectus Supplement and consider such risks in connection with an investment in such Securities.  See "RISK FACTORS".

Prospective investors should be aware that the acquisition of the securities described herein may have tax consequences both in the United States and in Canada.  Such consequences for investors who are resident in, or citizens of, the United States may not be described fully herein.  Prospective investors should read the tax discussion contained in the applicable Prospectus Supplement with respect to a particular offering of Securities.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION (THE "SEC") NOR HAS THE SEC PASSED UPON THE ACCURACY OR THE ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

The specific terms of the Securities with respect to a particular offering will be set out in one or more Prospectus Supplements and may include, where applicable: (i) in the case of Common Shares, the number of Common Shares offered, the offering price and any other specific terms; (ii) in the case of Warrants, the number of Warrants offered, the offering price, the designation, number and terms of the Common Shares issuable upon exercise of the Warrants, any procedures that will result in the adjustment of these numbers, the exercise price, dates and periods of exercise, the currency in which the Warrants are issued and any other specific terms; (iii) in the case of Subscription Receipts, the number of Subscription Receipts offered, the offering price, the procedures for the exchange of the Subscription Receipts for Common Shares or Warrants, as the case may be, and any other specific terms; (iv) in the case of Debt Securities, the specific designation, aggregate principal amount, the currency or the currency unit for which the Debt Securities may be purchased, the maturity, interest provisions, authorized denominations, offering price, covenants, events of default, any terms for redemption, any exchange or conversion terms, whether the debt is senior, senior subordinated or subordinated, whether the debt is secured or unsecured and any other terms specific to the Debt Securities being offered; and (v) in the case of Units, the designation, number and terms of the Common Shares, Warrants, Subscription Receipts or Debt Securities comprising the Units.  Where required by statute, regulation or policy, and where Securities are offered in currencies other than Canadian dollars, appropriate disclosure of foreign exchange rates applicable to the Securities will be included in the Prospectus Supplement describing the Securities.

ii

In addition, the Debt Securities that may be offered may be guaranteed by certain direct and indirect subsidiaries of Taseko with respect to the payment of the principal, premium, if any, and interest on the Debt Securities.  The Company expects that any guarantee provided in respect of senior Debt Securities would constitute a senior and unsecured obligation of the applicable guarantor.  For a more detailed description of the Debt Securities that may be offered, see "Description of Securities - Debt Securities - Guarantees", below.

All information permitted under applicable securities legislation to be omitted from the Prospectus will be contained in one or more Prospectus Supplement(s) that will be delivered to purchasers together with the Prospectus.  Each Prospectus Supplement will be incorporated by reference into the Prospectus for the purposes of applicable securities legislation as of the date of the Prospectus Supplement and only for the purposes of the distribution of the Securities to which the Prospectus Supplement pertains.  Investors should read the Prospectus and any applicable Prospectus Supplement carefully before investing in the Company's Securities. 

This Prospectus constitutes a public offering of the Securities only in those jurisdictions where they may be lawfully offered for sale and only by persons permitted to sell the Securities in such jurisdictions.  We may offer and sell Securities to, or through, underwriters or dealers, directly to one or more other purchasers, or through agents pursuant to exemptions from registration or qualification under applicable securities laws. A Prospectus Supplement relating to each issue of Securities will set forth the names of any underwriters, dealers or agents involved in the offering and sale of the Securities and will set forth the terms of the offering of the Securities, the initial issue price (in the event that the offering is a fixed price distribution), the method of distribution of the Securities, including, to the extent applicable, the proceeds to us and any fees, discounts, concessions or other compensation payable to the underwriters, dealers or agents, and any other material terms of the plan of distribution.  If offered on a varying price basis, the Securities may be offered at market prices prevailing at the time of sale, at prices determined by reference to such prevailing market prices, with or without discounts, or at negotiated prices, which prices may vary as between purchasers and during the period of distribution of the Securities. In connection with any offering of the Securities, other than an "at-the-market distribution", unless otherwise specified in a Prospectus Supplement, the underwriters or agents may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at a higher level than that which might exist in the open market.  Such transaction, if commenced, may be interrupted or discontinued at any time.  See "Plan of Distribution".

We may effect sales of the Common Shares from time to time in one or more transactions at non-fixed prices pursuant to transactions that are deemed to be "at-the-market distributions" as defined in National Instrument 44-102 - Shelf Distributions, including sales made directly on the TSX or NYSE American or other existing trading markets for the Common Shares, and as set forth in a Prospectus Supplement for such purpose. No underwriter or dealer involved in an "at-the-market distribution" under this Prospectus, no affiliate of such an underwriter or dealer and no person or company acting jointly or in concert with such an underwriter or dealer will over-allot securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Common Shares.

A Prospectus Supplement containing the specific terms of an offering of Securities will be delivered to purchasers of such Securities together with this Prospectus and will be deemed to be incorporated by reference into this Prospectus as of the date of such Prospectus Supplement, but only for the purposes of the offering of Securities covered by that Prospectus Supplement.  Investors should read the Prospectus and any applicable Prospectus Supplement carefully before investing in the Company's Securities. 

Any template version of any "marketing materials" (as such term is defined in NI 44-101) filed after the date of a Prospectus Supplement and before the termination of the distribution of the Securities offered pursuant to such Prospectus Supplement (together with this Prospectus) is deemed to be incorporated by reference in such Prospectus Supplement. 

FORWARD LOOKING STATEMENTS

The Prospectus, including the documents incorporated by reference, contain forward-looking statements and forward-looking information (collectively referred to as "forward-looking statements") which may not be based on historical fact, including without limitation statements regarding our expectations in respect of future financial position, business strategy, future production, reserve potential, exploration drilling, exploitation activities, events or developments that we expect to take place in the future, projected costs and plans and objectives.  Often, but not always, forward-looking statements can be identified by the use of the words "believes", "may", "plan", "will", "estimate", "scheduled", "continue", "anticipates", "intends", "expects", and similar expressions. 

Such statements reflect our current views with respect to future events and are subject to risks and uncertainties and are necessarily based upon a number of estimates and assumptions that, while considered reasonable by the Company, are inherently subject to significant business, economic, competitive, political and social uncertainties and known or unknown risks and contingencies.  Many factors could cause our actual results, performance or achievements to be materially different from any future results, performance, or achievements that may be expressed or implied by such forward-looking statements, including, among others:

•uncertainties about the future market price of copper and the other metals that we produce or may seek to produce;

•changes in general economic conditions, the financial markets, inflation and interest rates and in the demand and market price for our input costs, such as diesel fuel, reagents, 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 impact of rising interest rates by central banks on our current and future borrowing costs, including the impact that inflation could have on the estimated costs related to the construction of the Company's Florence Copper project (the "Florence Copper Project" or "Florence Copper");

3

•uncertainties resulting from the war in Ukraine, and the accompanying international response including economic sanctions levied against Russia and other countries, which has disrupted the global economy, created increased volatility in commodity markets (including oil and gas prices), and disrupted international trade and financial markets, all of which have an ongoing and uncertain effect on global economics, supply chains, availability of materials and equipment and execution timelines for project development;

•uncertainties about the continuing impact of the novel coronavirus ("COVID-19") and the response of local, provincial, state, federal and international governments to the ongoing threat of COVID-19, on our operations (including our suppliers, customers, supply chains, employees and contractors) and economic conditions generally including stimulation measures implemented, rising inflation levels and in particular with respect to the demand for copper and other metals we produce;

•inherent risks associated with mining operations, including our current mining operations at Gibraltar, and their potential impact on our ability to achieve our production estimates;

•uncertainties as to our ability to control our operating costs, including inflationary cost pressures at Gibraltar without impacting our planned copper production;

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

•uncertainties related to the feasibility study for the Florence Copper Project and our other development projects which provide estimates of future production, expected or anticipated capital and operating costs, expenditures and economic returns from these mining projects;

•uncertainties related to the accuracy of our estimates of Mineral Reserves (as defined below), Mineral Resources (as defined below), production rates and timing of production, future production and future cash and total costs of production and milling;

•the risk that grades and recoveries at Gibraltar may not remain consistent with our mineral reserve expectations and current mine plans;

•the risk that we may not be able to expand or replace reserves as our existing mineral reserves are mined;

•the availability of, and uncertainties relating to the development of, additional financing necessary for the advancement of our development projects, including with respect to our ability to obtain any remaining construction financing potentially needed to move forward with commercial operations at Florence Copper;

•our ability to comply with the extensive governmental regulation to which our business is subject;

4

•uncertainties related to our ability to obtain necessary title, licenses and permits for our development projects and project delays due to third party opposition, particularly in respect to Florence Copper that requires one key regulatory permit from the U.S. Environmental Protection Agency ("EPA") in order to advance to a construction decision and commercial operations;

•uncertainties related to the Florence Copper Project execution plan, including inflation risk and the potential impact of supply chain disruptions on our construction schedule, which could impact the transition into construction operations after the final permit is received from the EPA;

•uncertainties relating to the satisfaction of the conditions for the advance of the US$50 million deposit under our copper stream agreement with Mitsui for the construction of the Florence Copper commercial facility and our US$25 million equipment commitment from Bank of America;

•uncertainties relating to our ability to secure premium pricing for copper produced at the Florence Copper facility based on its low-carbon characteristics;

•the risk that until construction of the commercial facility at Florence Copper is complete and ramped up, there could be increases in actual costs incurred that will negatively impact our estimates for current projected economics for commercial operations at Florence Copper;

•uncertainties related to First Nations claims and consultation issues;

•our reliance on rail transportation and port terminals for shipping our copper concentrate production from Gibraltar;

•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 and mine closure and bonding requirements;

•our current dependence solely on our 87.5% interest in Gibraltar (as defined below) for revenues and operating cashflows;

•our ability to collect payments from customers, extend existing concentrate off-take agreements or enter into new agreements;

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

•labour strikes, work stoppages, or other interruptions to, or difficulties in, the employment of labour in markets in which we operate our mine, industrial accidents, equipment failure, weather related breakdowns or other events or occurrences, including third party interference that interrupt the production of minerals in our mine;

•environmental hazards and risks associated with climate change, including the potential for damage to infrastructure and stoppages of operations due to forest fires, flooding, extreme cold, drought, or other natural events in the vicinity of our operations;

5

•litigation risks and the inherent uncertainty of litigation, including litigation to which Florence Copper could be subject to;

•our actual costs of reclamation and mine closure may exceed our current estimates of these liabilities;

•our ability to meet the financial reclamation security requirements for the Gibraltar mine, Florence Copper and other development projects;

•the capital intensive nature of our business both to sustain current mining operations and to develop any new projects, including Florence Copper;

•our reliance upon key management and operating personnel;

•the competitive environment in which we operate;

•the effects of forward selling instruments to protect against fluctuations in copper prices, foreign exchange, interest rates or input costs such as diesel fuel; and

•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; and Management Discussion and Analysis ("MD&A"), quarterly reports and material change reports filed with and furnished to securities regulators, and those risks which are discussed in the 2022 AIF under the heading "Risk Factors".

Such information is included, among other places, in this Prospectus under the headings "The Company" and "Use of Proceeds", in our 2022 AIF under the headings "Taseko's Business" and "Risk Factors" and in our 2022 Annual MD&A, each of which documents are incorporated by reference into this Prospectus.

Should one or more of these risks and uncertainties materialize, or should underlying factors or assumptions prove incorrect, actual results may vary materially from those described in forward-looking statements.  Material factors or assumptions involved in developing forward-looking statements include, without limitation, that:

•the price of copper and other metals will not decline significantly or for a protracted period of time;

•our mining operations will not experience any significant production disruptions that would materially affect our production forecasts or our revenues;

•our estimates regarding future capital and operating costs, including factoring in potential inflation impacts, at Gibraltar will be accurate;

•grades and recoveries at Gibraltar remain consistent with our mineral reserve expectations and current mine plans;

6

•the results from our operations of the Production Test Facility ("PTF") and updated technical report at Florence Copper will continue to support that commercial operations at Florence Copper are technically and economically feasible;

•we will be able to obtain any remaining construction financing necessary for us to advance Florence Copper to a positive construction decision and eventual commercial production;

•we will be able to obtain the required permits necessary for us to proceed with construction and commercial operations at Florence;

•we will be able to satisfy the conditions for the advance of the US$50 million deposit under our copper stream agreement with Mitsui for the construction of the Florence Copper facility;

•potential supply chain disruptions and associated logistical challenges will not significantly impact our planned capital projects, including our expected development of Florence;

•potential future litigation regarding Florence Copper will not materially impede or delay our ability to proceed with construction and commercial operations at Florence;

•there are no changes to any existing agreements or relationships with affected First Nations groups which would materially and adversely impact our operations;

•there are no adverse regulatory changes affecting any of our operations;

•exchange rates, inflationary pressure on prices of key consumables, costs of power, labour, material costs, supplies and services, and other cost assumptions at our projects are not significantly higher than prices assumed in planning;

•our mineral reserve and resource estimates and the assumptions on which they are based, are accurate;

•our estimates of reclamation liabilities, mine closure costs and bonding needs are accurate; and

•we will continue to generate positive cash flows from Gibraltar and be able to secure additional funding necessary for the development and continued advancement of Gibraltar and our development projects, including Florence Copper.

These factors should be considered carefully and readers are cautioned not to place undue reliance on the forward-looking statements.  Readers are cautioned that the foregoing list of risk factors is not exhaustive and it is recommended that prospective investors carefully read the more complete discussion of risks and uncertainties facing the Company included in the Prospectus.  See "Risk Factors" in the 2022 AIF for a more detailed discussion of these risks.

Although we believe that the expectations conveyed by the forward-looking statements are reasonable based on the information available to us on the date such statements were made, no assurances can be given as to future results, approvals or achievements.  The forward-looking statements contained in this Prospectus and the documents incorporated by reference herein are expressly qualified by this cautionary statement.  We disclaim any duty to update any of the forward-looking statements after the date of the Prospectus to conform such statements to actual results or to changes in our expectations except as otherwise required by applicable law.

GLOSSARY OF CERTAIN TECHNICAL TERMS

As a Canadian issuer, we are required to comply with reporting standards in Canada that require that we make disclosure regarding our mineral properties, including any estimates of mineral reserves and resources, in accordance with Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Unless otherwise indicated, all resource estimates contained in or incorporated by reference in this Prospectus have been prepared in accordance with NI 43-101.

This Prospectus uses the certain technical terms presented below as they are defined in accordance with the CIM Definition Standards on Mineral Resources and Reserves (the "CIM Standards") adopted by the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM Council").  Unless otherwise indicated, all reserve and resource estimates contained in or incorporated by reference in this Prospectus have been prepared in accordance with the CIM Standards, as required by NI 43-101.  The following definitions are reproduced from the latest version of the CIM Standards, which were adopted by the CIM Council on May 10, 2014:

feasibility study	A comprehensive technical and economic study of the selected development option for a mineral project that includes appropriately detailed assessments of applicable modifying factors together with any other relevant operational factors and detailed financial analysis that are necessary to demonstrate, at the time of reporting, that extraction is reasonably justified (economically mineable).  The results of the study may reasonably serve as the basis for a final decision by a proponent or financial institution to proceed with, or finance, the development of the project.  The confidence level of the study will be higher than that of a pre-feasibility study.
indicated mineral resource	That part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit.  Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation.  An indicated mineral resource has a lower level of confidence than that applying to a measured mineral resource and may only be converted to a probable mineral reserve.
inferred mineral resource	That part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling.  Geological evidence is sufficient to imply but not verify geological and grade or quality continuity.  An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve.  It is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration.

8

measured mineral resource	That part of a mineral resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of modifying factors to support detailed mine planning and final evaluation of the economic viability of the deposit.  Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation.  A measured mineral resource has a higher level of confidence than that applying to either an indicated mineral resource or an inferred mineral resource.  It may be converted to a proven mineral reserve or to a probable mineral reserve.
mineral reserve	The economically mineable part of a measured and/or indicated mineral resource.  It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at pre-feasibility or feasibility level as appropriate that include application of modifying factors.  Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.  The reference point at which mineral reserves are defined, usually the point where the ore is delivered to the processing plant, must be stated.  It is important that, in all situations where the reference point is different, such as for a saleable product, a clarifying statement is included to ensure that the reader is fully informed as to what is being reported. The public disclosure of a mineral reserve must be demonstrated by a pre-feasibility study or feasibility study.
mineral resource	A concentration or occurrence of solid material of economic interest in or on the Earth's crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction.  The location, quantity, grade or quality, continuity and other geological characteristics of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling.
modifying factors	Considerations used to convert mineral resources to mineral reserves.  These include, but are not restricted to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors.
NI 43-101	Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects, as adopted by the Canadian Securities Administrators.
pre-feasibility study	A comprehensive study of a range of options for the technical and economic viability of a mineral project that has advanced to a stage where a preferred mining method, in the case of underground mining, or the pit configuration, in the case of an open pit, is established and an effective method of mineral processing is determined.  It includes a financial analysis based on reasonable assumptions on the modifying factors and the evaluation of any other relevant factors which are sufficient for a Qualified Person, acting reasonably, to determine if all or part of the mineral resource may be converted to a mineral reserve at the time of reporting.  A pre-feasibility is at a lower confidence level than a feasibility study.

9

probable mineral reserve	The economically mineable part of an Indicated, and in some circumstances, a measured mineral resource.  The confidence in the modifying factors applying to a probable mineral reserve is lower than that applying to a proven mineral reserve.
proven mineral reserve	The economically mineable part of a measured mineral resource.  A proven mineral reserve implies a high degree of confidence in the modifying factors.

In addition, we use the following defined terms in this Prospectus:

BCBCA	Business Corporations Act (British Columbia).
Exchange Act	The United States Securities Exchange Act of 1934, as amended.
SEC	The United States Securities and Exchange Commission.
U.S. Securities Act	The United States Securities Act of 1933, as amended.

CAUTIONARY NOTES TO UNITED STATES INVESTORS CONCERNING
CANADIAN MINERAL PROPERTY DISCLOSURE STANDARDS

We are permitted under a multijurisdictional disclosure system adopted by the securities regulatory authorities in Canada and the United States to prepare this Prospectus Supplement in accordance with the disclosure requirements of Canada. Prospective investors in the United States should be aware that such requirements are different from those of the United States.

The Company is subject to the reporting requirements of the applicable Canadian securities laws, and as a result reports the mineral reserves and mineral resources of the projects it has an interest in according to Canadian standards. Technical disclosure regarding our properties included herein and in the documents incorporated herein by reference has not been prepared in accordance with the requirements of U.S. securities laws.

Unless otherwise indicated, all mineral reserve and mineral resource estimates included in this prospectus and the documents incorporated by reference herein have been prepared in accordance with NI 43-101 and the CIM Standards. NI 43-101 is a rule developed by the Canadian Securities Administrators, which established standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The terms "mineral reserve", "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with NI 43-101 and the CIM Standards. The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements (the "SEC Modernization Rules") for issuers whose securities are registered with the SEC under the United States Securities Exchange Act of 1934, as amended (the "Exchange Act"). The SEC Modernization Rules replaced the historical disclosure requirements for mining registrants that were included in SEC Industry Guide 7. As a foreign private issuer that files its annual report on Form 40-F with the SEC pursuant to the multijurisdictional disclosure system, the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Standards. If the Company ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the multijurisdictional disclosure system, then the Company will be subject to the SEC Modernization Rules which differ from the requirements of NI 43-101 and the CIM Standards.

10

As a result of the adoption of the SEC Modernization Rules, 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 CIM Standards that are required under NI 43-101.  While the SEC now recognizes "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", U.S. investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of the "inferred mineral resources" exist. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms are "substantially similar" to CIM Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.

NOTE TO UNITED STATES READERS REGARDING DIFFERENCES BETWEEN UNITED STATES AND CANADIAN FINANCIAL REPORTING PRACTICES

We prepare our financial statements in accordance with International Financial Reporting Standards ("IFRS"), as issued by the International Accounting Standards Board (the "IASB"), which differs from U.S. generally accepted accounting principles ("U.S. GAAP").  Accordingly, our financial statements incorporated by reference in the Prospectus, and in the documents incorporated by reference in this Prospectus, may not be comparable to financial statements of United States companies prepared in accordance with U.S. GAAP. 

CURRENCY PRESENTATION AND EXCHANGE RATE INFORMATION

Unless stated otherwise or as the context otherwise requires, all references to dollar amounts in this Prospectus and any Prospectus Supplement are references to Canadian dollars.  References to "$" or "C$" are to Canadian dollars and references to "U.S. dollars" or "US$" are to United States dollars.

Except as otherwise noted in our 2022 AIF and the Company's financial statements and related management's discussion and analysis of financial condition and results of operations of the Company that are incorporated by reference into this Prospectus, the financial information contained in such documents is expressed in Canadian dollars.

THE COMPANY

Taseko is a copper-focused mining company that seeks to create long-term shareholder value by acquiring, developing, and operating large tonnage mineral deposits in North America which are capable of supporting a mine for decades. The Company’s principal operating asset is the 87.5% owned Gibraltar Mine, which is located in central British Columbia and is one of the largest copper mines in North America. Taseko also owns Florence Copper, which is projected to be a low-cost copper producer, expected to manufacture high quality copper cathode in the United States, with potential to secure premium pricing based on its low-carbon characteristics. Taseko also owns the Yellowhead copper, New Prosperity gold-copper, and Aley niobium projects.

The Company was incorporated on April 15, 1966 under the laws of the Province of British Columbia and is governed by the BCBCA.  Our registered office is located at Suite 1500, 1055 West Georgia Street, Vancouver, British Columbia, V6E 4N7, and our operational head office is located at 12th Floor, 1040 West Georgia Street, Vancouver, British Columbia, V6E 4H1. We operate our business through our subsidiaries, as described in our 2022 AIF.

Gibraltar

Our principal operating asset is our 87.5% interest in the Gibraltar Mine in British Columbia, Canada. Gibraltar is the second largest open pit copper mine in Canada, having produced 97 million pounds of copper and 1.1 million pounds of molybdenum (on a 100% basis) in 2022. Gibraltar has an expected mine life of at least 22 years based on Proven and Probable Sulphide Mineral Reserves of 676 million tons at a grade of 0.25% copper as of December 31, 2022.

14

Between 2006 and 2013, the Company expanded and modernized the Gibraltar Mine ore concentrator, added a second ore concentrator, increased the mining fleet and made other production improvements at the mine. Following this period of mine expansion and capital expenditure, Gibraltar has achieved a stable level of operations and the Company’s focus is on further improvements to operating practices to reduce unit costs and increase production.  The Company increased its effective ownership stake in Gibraltar from 75% to 87.5% in 2023.

Florence Copper

Taseko is proceeding with the development of Florence Copper in Arizona. Once completed and in operation, Florence Copper is projected to be a low-cost producer of low carbon copper in the United States.

The development of Florence Copper is occurring in two phases. For the first phase, Florence Copper completed construction of a PTF in 2018 with PTF wellfield operations commencing in the fourth quarter of 2018. Operation of the PTF wellfield performed to its design and the small- scale SX/EW plant produced 1.1 million pounds of copper cathode before the leaching test phase was completed in June 2020. The PTF operation is now finishing its final rinsing process which is expected to be completed later this year. The second phase of Florence Copper will be the construction and operation of the commercial in-situ copper recovery facility.

In December 2020, the Company received the Aquifer Protection Permit from the Arizona Department of Environmental Quality. The Company is awaiting the issuance of the commercial Underground Injection Control (“UIC”) permit from the 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 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.

Detailed engineering and design for the commercial production facility is substantially completed and procurement activities are well advanced. The Company has purchased the major long-lead processing equipment associated with the SX/EW plant and the equipment has now been delivered to the Florence site.

The Company’s latest technical report on Florence published on March 30, 2023 estimates remaining capital costs for the commercial facility of US$232 million. At a copper price of US$3.75 per pound, Florence Copper is expected to generate an after-tax internal rate of return of 47%, an after-tax net present value of US$930 million at an 8% discount rate, and an after-tax payback period of 2.6 years.

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, which is exercisable by Mitsui within a three-year period following completion of construction of the commercial production facility.  As part of the arrangement, Taseko and Mitsui have entered into an offtake contract for 81% of the copper cathode produced at Florence Copper during the initial years of production. Refer to the 2022 AIF for additional details regarding the Mitsui copper stream arrangement.

15

In January 2023, the Company received an underwritten commitment for US$25 million from Banc of America Leasing and Capital, LLC. Proceeds from this financing will be available to fund costs associated with the SX/EW plant for the Florence Copper commercial production facility. Financing is subject to execution of definitive documentation, customary closing conditions, and receipt of the UIC permit.

Other Development Projects

We have a diverse pipeline of wholly-owned development projects at various stages of technical and economic feasibility studies, including the Yellowhead copper project, the Aley niobium project, and the New Prosperity gold and copper project.

Business Strategy

Our 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.  All of our producing and development projects are located in British Columbia and Arizona. Our project focus is currently on the development of Florence Copper.

PLAN OF DISTRIBUTION

We may sell the Securities to or through underwriters or dealers, and also may sell Securities to one or more other purchasers directly or through agents, including sales pursuant to ordinary brokerage transactions and transactions in which a broker-dealer solicits purchasers.  Underwriters may sell Securities to or through dealers.  We will file a Prospectus Supplement in connection with each offering of Securities.  Each Prospectus Supplement will set forth the terms of the offering, including the type of Security to be sold, the name or names of any underwriters, dealers or agents and any fees or compensation payable to them in connection with the offering and sale of a particular series or issue of Securities, the public offering price or prices of the Securities and the proceeds to the Company from the sale of the Securities.

The Securities may be sold, from time to time in one or more transactions at a fixed price or prices which may be changed or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices, including sales in transactions that are deemed to be "at-the-market distributions" which may be made directly on the TSX, NYSE American or other existing trading markets for the Securities.  The prices at which the Securities may be offered may vary as between purchasers and during the period of distribution.  If, in connection with the offering of Securities at a fixed price or prices, the underwriters have made a bona fide effort to sell all of the Securities at the initial offering price fixed in the applicable Prospectus Supplement, the public offering price may be decreased and thereafter further changed, from time to time, to an amount not greater than the initial public offering price fixed in such Prospectus Supplement, in which case the compensation realized by the underwriters will be decreased by the amount that the aggregate price paid by purchasers for the Securities is less than the gross proceeds paid by the underwriters to the Company.

19

If underwriters are used in an offering, the Securities offered thereby will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase Securities will be subject to the conditions precedent agreed upon by the parties and the underwriters will be obligated to purchase all Securities under that offering if any are purchased. Any public offering price and any discounts or concessions allowed or re-allowed or paid to agents, underwriters or dealers may be changed from time to time.

Underwriters, dealers and agents who participate in the distribution of the Securities may be entitled under agreements to be entered into with the Company to indemnification by the Company against certain liabilities, including liabilities under the U.S. Securities Act and Canadian securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof.  Such underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for, the Company in the ordinary course of business.

In connection with any offering of Securities, other than an "at-the-market distribution", the underwriters may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at a level above that which might otherwise prevail in the open market.  Such transactions, if commenced, may be discontinued at any time. No underwriter of an at-the-market distribution, and no person or company acting jointly or in concert with such underwriter, may, in connection with an at-the-market  distribution, enter into any transaction that is intended to stabilize or maintain the market price of the security or securities of the same class as the securities distributed in an at-the-market distribution under this Prospectus, including selling an aggregate number or principal amount of securities that would result in the underwriter creating an over-allocation position in the securities.

Unless otherwise specified in the applicable Prospectus Supplement, we do not intend to list any of the Securities other than the Common Shares on any securities exchange.  Any underwriters, dealers or agents to or through which Securities other than the Common Shares are sold by us for public offering and sale may make a market in such Securities, but such underwriters, dealers or agents will not be obligated to do so and may discontinue any such market making at any time and without notice.  No assurance can be given that a market for trading in Securities of any series or issue will develop or as to the liquidity of any such market, whether or not the Securities are listed on a securities exchange.

Each class or series of Warrants, Subscription Receipts, Debt Securities and Units will be a new issue of Securities with no established trading market. Unless otherwise specified in the applicable Prospectus Supplement, Warrants, Subscription Receipts, Debt Securities or Units will not be listed on any securities or stock exchange. Unless otherwise specified in the applicable Prospectus Supplement, there is no market through which the Warrants, Subscription Receipts, Debt Securities or Units may be sold and purchasers may not be able to resell Warrants, Subscription Receipts, Debt Securities or Units purchased under this Prospectus or any Prospectus Supplement. This may affect the pricing of the Warrants, Subscription Receipts, Debt Securities or Units in the secondary market, the transparency and availability of trading prices, the liquidity of the Securities, and the extent of issuer regulation. Subject to applicable laws, certain dealers may make a market in the Warrants, Subscription Receipts, Debt Securities or Units, as applicable, but will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given that any dealer will make a market in the Warrants, Subscription Receipts, Debt Securities or Units or as to the liquidity of the trading market, if any, for the Warrants, Subscription Receipts, Debt Securities or Units.

•whether we will issue the Debt Securities as global securities and, if so, the identity of the depositary for the global securities;

•whether we will issue the Debt Securities as unregistered securities, registered securities or both;

•any changes or additions to, or deletions of, events of default or covenants whether or not such events of default or covenants are consistent with the events of default or covenants in the Indenture;

•the applicability of, and any changes or additions to, the provisions for defeasance described under "Defeasance" below;

25

•whether the holders of any series of Debt Securities have special rights if specified events occur;

•the terms, if any, for any conversion or exchange of the Debt Securities for any other securities;

•provisions as to modification, amendment or variation of any rights or terms attaching to the Debt Securities; and

•any other terms, conditions, rights and preferences (or limitations on such rights and preferences).

Unless stated otherwise in the applicable Prospectus Supplement, no holder of Debt Securities will have the right to require us to repurchase the Debt Securities and there will be no increase in the interest rate if we become involved in a highly leveraged transaction or if we have a change of control.

We may issue Debt Securities bearing no interest or interest at a rate below the prevailing market rate at the time of issuance, and offer and sell the Debt Securities at a discount below their stated principal amount.  We may also sell any of the Debt Securities for a foreign currency or currency unit, and payments on the Debt Securities may be payable in a foreign currency or currency unit.  In any of these cases, we will describe certain Canadian federal and U.S. federal income tax consequences and other special considerations in the applicable Prospectus Supplement.

We may issue Debt Securities with terms different from those of Debt Securities previously issued and, without the consent of the holders thereof, we may reopen a previous issue of a series of Debt Securities and issue additional Debt Securities of such series (unless the reopening was restricted when such series was created).

Guarantees

Our payment obligations under any series of Debt Securities may be guaranteed by certain of our direct or indirect subsidiaries.  In order to comply with certain registration statement form requirements under U.S. law, these guarantees may in turn be guaranteed by the Company.  The terms of such guarantees will be set forth in the applicable Prospectus Supplement.

Ranking and Other Indebtedness

Unless otherwise indicated in an applicable Prospectus Supplement, and except to the extent prescribed by law, each series of Debt Securities shall be senior, unsubordinated and unsecured obligations of the Company and shall rank pari passu and ratably without preference among themselves and pari passu with all other senior, unsubordinated and unsecured obligations of the Company.

Our Board of Directors may establish the extent and manner, if any, to which payment on or in respect of a series of Debt Securities will be senior, senior subordinated or will be subordinated to the prior payment of the Company's other liabilities and obligations, and whether the payment of principal, premium, if any, and interest, if any, will be guaranteed by any other person and the nature and priority of any security.

Debt Securities in Global Form

The Depositary and Book-Entry

Unless otherwise specified in the applicable Prospectus Supplement, a series of the Debt Securities may be issued in whole or in part in global form as a "global security" and will be registered in the name of or issued in bearer form and be deposited with a depositary, or its nominee, each of which will be identified in the applicable Prospectus Supplement relating to that series.  Unless and until exchanged, in whole or in part, for the Debt Securities in definitive registered form, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of the depositary, by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any such nominee to a successor of the depositary or a nominee of the successor.

The specific terms of the depositary arrangement with respect to any portion of a particular series of the Debt Securities to be represented by a global security will be described in the applicable Prospectus Supplement relating to such series.  We anticipate that the provisions described in this section will apply to all depositary arrangements.

Upon the issuance of a global security, the depositary therefor or its nominee will credit, on its book entry and registration system, the respective principal amounts of the Debt Securities represented by the global security to the accounts of such persons, designated as "participants", having accounts with such depositary or its nominee.  Such accounts shall be designated by the underwriters, dealers or agents participating in the distribution of the Debt Securities or by the Company if such Debt Securities are offered and sold directly by the Company.  Ownership of beneficial interests in a global security will be limited to participants or persons that may hold beneficial interests through participants.  Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary therefor or its nominee (with respect to interests of participants) or by participants or persons that hold through participants (with respect to interests of persons other than participants).  The laws of some states in the United States may require that certain purchasers of securities take physical delivery of such securities in definitive form.

So long as the depositary for a global security or its nominee is the registered owner of the global security or holder of a global security in bearer form, such depositary or such nominee, as the case may be, will be considered the sole owner or holder of the Debt Securities represented by the global security for all purposes under the Indenture.  Except as provided below, owners of beneficial interests in a global security will not be entitled to have a series of the Debt Securities represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of such series of the Debt Securities in definitive form and will not be considered the owners or holders thereof under the Indenture.

Any payments of principal, premium, if any, and interest, if any, on global securities registered in the name of a depositary or securities registrar will be made to the depositary or its nominee, as the case may be, as the registered owner of the global security representing such Debt Securities.  None of the Company, any trustee or any paying agent for the Debt Securities represented by the global securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

27

We expect that the depositary for a global security or its nominee, upon receipt of any payment of principal, premium, if any, or interest, if any, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the records of such depositary or its nominee.  We also expect that payments by participants to owners of beneficial interests in a global security held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in "street name", and will be the responsibility of such participants.

Discontinuance of Depositary's Services

If a depositary for a global security representing a particular series of the Debt Securities is at any time unwilling or unable to continue as depositary or, if at any time the depositary for such series shall no longer be registered or in good standing under the Exchange Act, and a successor depositary is not appointed by us within 90 days, we will issue such series of the Debt Securities in definitive form in exchange for a global security representing such series of the Debt Securities.  If an event of default under the Indenture has occurred and is continuing, Debt Securities in definitive form will be printed and delivered upon written request by the holder to the appropriate trustee.  In addition, we may at any time and in our sole discretion determine not to have a series of the Debt Securities represented by a global security and, in such event, will issue a series of the Debt Securities in definitive form in exchange for all of the global securities representing that series of Debt Securities.

Debt Securities in Definitive Form

A series of the Debt Securities may be issued in definitive form, solely as registered securities, solely as unregistered securities or as both registered securities and unregistered securities.  Registered securities will be issuable in denominations of $2,000 and integral multiples of $1,000 and unregistered securities will be issuable in denominations of $5,000 and integral multiples of $5,000 or, in each case, in such other denominations as may be set out in the terms of the Debt Securities of any particular series.  Unless otherwise indicated in the applicable Prospectus Supplement, unregistered securities will have interest coupons attached.

Unless otherwise indicated in the applicable Prospectus Supplement, payment of principal, premium, if any, and interest, if any, on the Debt Securities in definitive form will be made at the office or agency we designate, or at our option we can pay principal, interest, if any, and premium, if any, by check mailed to the address of the person entitled at the address appearing in the security register of the trustee or electronic funds wire transfer to an account of persons who meet certain thresholds set out in the Indenture who are entitled to receive payments by wire transfer.  Unless otherwise indicated in the applicable Prospectus Supplement, payment of interest, if any, will be made to the persons in whose name the Debt Securities are registered at the close of business on the day or days we specify.

At the option of the holder of Debt Securities, registered securities of any series will be exchangeable for other registered securities of the same series, of any authorized denomination and of a like aggregate principal amount.  If, but only if, provided in an applicable Prospectus Supplement, unregistered securities (with all unmatured coupons, except as provided below, and all matured coupons in default) of any series may be exchanged for registered securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor.  In such event, unregistered securities surrendered in a permitted exchange for registered securities between a regular record date or a special record date and the relevant date for payment of interest shall be surrendered without the coupon relating to such date for payment of interest, and interest will not be payable on such date for payment of interest in respect of the registered security issued in exchange for such unregistered security, but will be payable only to the holder of such coupon when due in accordance with the terms of the Indenture.  Unless otherwise specified in an applicable Prospectus Supplement, unregistered securities will not be issued in exchange for registered securities.

28

The applicable Prospectus Supplement may indicate the places to register a transfer of the Debt Securities in definitive form.  Service charges may be payable by the holder for any registration of transfer or exchange of the Debt Securities in definitive form, and we may, in certain instances, require a sum sufficient to cover any tax or other governmental charges payable in connection with these transactions.

We shall not be required to:

•issue, register the transfer of or exchange any series of the Debt Securities in definitive form during a period beginning at the opening of 15 days before any selection of securities of that series of the Debt Securities to be redeemed and ending on the relevant date of notice of such redemption, as provided in the Indenture;

•register the transfer of or exchange any registered security in definitive form, or portion thereof, called for redemption, except the unredeemed portion of any registered security being redeemed in part;

•exchange any unregistered security called for redemption except to the extent that such unregistered security may be exchanged for a registered security of that series and like tenor; provided that such registered security will be simultaneously surrendered for redemption; or

•issue, register the transfer of or exchange any of the Debt Securities in definitive form which have been surrendered for repayment at the option of the holder, except the portion, if any, of such Debt Securities not to be so repaid.

Provision of Financial Information

To the extent the Indenture is governed by the Trust Indenture Act, we will file with the Trustee within 15 days after the Company files the same with the SEC, (i) copies of the annual reports containing audited financial statements and copies of quarterly reports containing unaudited financial statements and (ii) copies of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) which the Company may be required to file with or furnish to the SEC pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934.

If we are not required to remain subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, we will continue to file with the SEC and provide the Trustee:

•within 140 days after the end of each fiscal year, annual reports on Form 20-F, 40-F or Form 10-K, as applicable (or any successor form), containing audited financial statements and the other financial information required to be contained therein (or required in such successor form); and

29

•within 60 days after the end of each of the first three fiscal quarters of each fiscal year, reports on Form 6-K or Form 10-Q (or any successor form), containing unaudited financial statements and the other financial information which, regardless of applicable requirements shall, at a minimum, contain such information required to be provided in quarterly reports under the laws of Canada or any province thereof to security holders of a corporation with securities listed on the Toronto Stock Exchange, whether or not the Company has any of its securities so listed.

Events of Default

Unless specified in the applicable Prospectus Supplement relating to a particular series of Debt Securities, the following is a summary of events which will, with respect to any series of the Debt Securities, constitute an event of default under the Indenture with respect to the Debt Securities of that series:

•the Company fails to pay principal of, or any premium on any Debt Security of that series when it is due and payable;

•the Company fails to pay interest payable on any Debt Security of that series when it becomes due and payable, and such default continues for 30 days;

•the Company fails to make any required sinking fund or analogous payment when due for that series of Debt Securities;

•the Company fails to observe or perform any of its covenants or agreements in the Indenture that affect or are applicable to the Debt Securities of that series for 90 days after written notice to the Company by the trustees or to the Company and the trustees by holders of at least 25% in aggregate principal amount of the outstanding Debt Securities of that series;

•certain events involving the Company's bankruptcy, insolvency or reorganization; and

•any other event of default provided for in that series of Debt Securities.

A default under one series of Debt Securities will not necessarily be a default under another series.  A trustee may withhold notice to the holders of the Debt Securities of any default, except in the payment of principal or premium, if any, or interest, if any, if in good faith it considers it in the interests of the holders to do so and so advises the Company in writing.

If an event of default for any series of Debt Securities occurs and continues, a trustee or the holders of at least 25% in aggregate principal amount of the Debt Securities of that series may require the Company to repay immediately:

•the entire principal and interest of the Debt Securities of the series; or

•if the Debt Securities are discounted securities, that portion of the principal as is described in the applicable Prospectus Supplement.

30

If an event of default relates to events involving the Company's bankruptcy, insolvency or reorganization, the principal of all Debt Securities will become immediately due and payable without any action by the trustee or any holder.

Subject to certain conditions, the holders of a majority of the aggregate principal amount of the Debt Securities of the affected series can rescind and annul an accelerated payment requirement.  If Debt Securities are discounted securities, the applicable Prospectus Supplement will contain provisions relating to the acceleration of maturity of a portion of the principal amount of the discounted securities upon the occurrence or continuance of an event of default.

Other than its duties in case of a default, a trustee is not obligated to exercise any of the rights or powers that it will have under the Indenture at the request or direction of any holders, unless the holders offer the trustee reasonable security or indemnity.  If they provide this reasonable security or indemnity, the holders of a majority in aggregate principal amount of any series of Debt Securities may, subject to certain limitations, direct the time, method and place of conducting any proceeding for any remedy available to a trustee, or exercising any trust or power conferred upon a trustee, for any series of Debt Securities.

We will be required to furnish to the trustees a statement annually as to its compliance with all conditions and covenants under the Indenture and, if the Company is not in compliance, the Company must specify any defaults.  We will also be required to notify the trustees as soon as practicable upon becoming aware of any event of default.

No holder of a Debt Security of any series will have any right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or a trustee, or for any other remedy, unless:

•the holder has previously given to the trustees written notice of a continuing event of default with respect to the Debt Securities of the affected series;

•the holders of at least 25% in principal amount of the outstanding Debt Securities of the series affected by an event of default have made a written request, and the holders have offered reasonable indemnity, to the trustees to institute a proceeding as trustees; and

•the trustees have failed to institute a proceeding, and have not received from the holders of a majority in aggregate principal amount of the outstanding Debt Securities of the series affected (or in the case of bankruptcy, insolvency or reorganization, all series outstanding) by an event of default a direction inconsistent with the request, within 60 days after receipt of the holders' notice, request and offer of indemnity.

However, such above-mentioned limitations do not apply to a suit instituted by the holder of a Debt Security for the enforcement of payment of the principal of or any premium, if any, or interest on such Debt Security on or after the applicable due date specified in such Debt Security.

Defeasance

When the Company uses the term "defeasance", it means discharge from its obligations with respect to any Debt Securities of or within a series under the Indenture.  Unless otherwise specified in the applicable Prospectus Supplement, if the Company deposits with a trustee cash, government securities or a combination thereof sufficient to pay the principal, interest, if any, premium, if any, and any other sums due to the stated maturity date or a redemption date of the Debt Securities of a series, then at the Company's option:

31

•the Company will be discharged from the obligations with respect to the Debt Securities of that series; or

•the Company will no longer be under any obligation to comply with certain restrictive covenants under the Indenture and certain events of default will no longer apply to the Company.

If this happens, the holders of the Debt Securities of the affected series will not be entitled to the benefits of the Indenture except for registration of transfer and exchange of Debt Securities and the replacement of lost, stolen, destroyed or mutilated Debt Securities.  These holders may look only to the deposited fund for payment on their Debt Securities.

To exercise the defeasance option, the Company must deliver to the trustees:

•an opinion of counsel in the United States to the effect that the holders of the outstanding Debt Securities of the affected series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of a defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance had not occurred;

•an opinion of counsel in Canada or a ruling from the Canada Revenue Agency to the effect that the holders of the outstanding Debt Securities of the affected series will not recognize income, gain or loss for Canadian federal, provincial or territorial income or other tax purposes as a result of a defeasance and will be subject to Canadian federal, provincial or territorial income tax and other tax on the same amounts, in the same manner and at the same times as would have been the case had the defeasance not occurred; and

•a certificate of one of the Company's officers and an opinion of counsel, each stating that all conditions precedent provided for relating to defeasance have been complied with.

If the Company is to be discharged from its obligations with respect to the Debt Securities, and not just from the Company's covenants, the U.S. opinion must be based upon a ruling from or published by the United States Internal Revenue Service or a change in law to that effect.

In addition to the delivery of the opinions described above, the following conditions must be met before the Company may exercise its defeasance option:

•no event of default or event that, with the passing of time or the giving of notice, or both, shall constitute an event of default shall have occurred and be continuing for the Debt Securities of the affected series;

32

•the Company is not an "insolvent person" within the meaning of applicable bankruptcy and insolvency legislation; and

•other customary conditions precedent are satisfied.

Modification and Waiver

Modifications and amendments of the Indenture may be made by the Company and the trustees pursuant to one or more supplemental indentures (a "Supplemental Indenture") with the consent of the holders of at least a majority in aggregate principal amount of the outstanding Debt Securities of each series affected by the modification.  However, without the consent of each holder affected, no such modification may:

•change the stated maturity of the principal of, premium, if any, or any instalment of interest, if any, on any Debt Security;

•reduce the principal, premium, if any, or rate of interest, if any, or change any obligation of the Company to pay any additional amounts;

•reduce the amount of principal of a debt security payable upon acceleration of its maturity or the amount provable in bankruptcy;

•change the place or currency of any payment;

•affect the holder's right to require the Company to repurchase the Debt Securities at the holder's option;

•impair the right of the holders to institute a suit to enforce their rights to payment;

•adversely affect any conversion or exchange right related to a series of Debt Securities;

•reduce the percentage of Debt Securities required to modify the Indenture or to waive compliance with certain provisions of the Indenture; or

•reduce the percentage in principal amount of outstanding Debt Securities necessary to take certain actions.

The holders of at least a majority in principal amount of outstanding Debt Securities of any series may on behalf of the holders of all Debt Securities of that series waive, insofar as only that series is concerned, past defaults under the Indenture and compliance by the Company with certain restrictive provisions of the Indenture.  However, these holders may not waive a default in any payment of principal, premium, if any, or interest on any Debt Security or compliance with a provision that cannot be modified without the consent of each holder affected.

The Company may modify the Indenture pursuant to a Supplemental Indenture without the consent of any holders to:

•evidence its successor under the Indenture;

33

•add covenants of the Company or surrender any right or power of the Company for the benefit of holders;

•add events of default;

•provide for unregistered securities to become registered securities under the Indenture and make other such changes to unregistered securities that in each case do not materially and adversely affect the interests of holders of outstanding Debt Securities;

•establish the forms of the Debt Securities;

•appoint a successor trustee under the Indenture;

•add provisions to permit or facilitate the defeasance and discharge of the Debt Securities as long as there is no material adverse effect on the holders;

•cure any ambiguity, correct or supplement any defective or inconsistent provision or make any other provisions in each case that would not materially and adversely affect the interests of holders of outstanding Debt Securities, if any; or

•change or eliminate any provisions of the Indenture where such change takes effect when there are no Debt Securities outstanding which are entitled to the benefit of those provisions under the Indenture.

Governing Law

To the extent the Indenture is governed by the Trust Indenture Act, the Indenture and the Debt Securities will be governed by and construed in accordance with the laws of the State of New York.

The Trustee

The Trustee under the Indenture or its affiliates may provide banking and other services to the Company in the ordinary course of their business.

The Indenture will contain certain limitations on the rights of the Trustee, as long as it or any of its affiliates remains the Company's creditor, to obtain payment of claims in certain cases or to realize on certain property received on any claim as security or otherwise.  The Trustee and its affiliates will be permitted to engage in other transactions with the Company.  If the Trustee or any affiliate acquires any conflicting interest and a default occurs with respect to the Debt Securities, the Trustee must eliminate the conflict or resign.

Resignation and Removal of Trustee

A trustee may resign or be removed with respect to one or more series of the Debt Securities and a successor trustee may be appointed to act with respect to such series.

34

Consent to Jurisdiction and Service

Under the Indenture, the Company will irrevocably appoint an authorized agent upon which process may be served in any suit, action or proceeding arising out of or relating to the Offered Debt Securities or the Indenture that may be instituted in any United States federal or New York state court located in The City of New York, and will submit to such non-exclusive jurisdiction.

Units

We may issue Units comprised of one or more of the other Securities described in the Prospectus in any combination.  Each Unit will be issued so that the holder of the Unit is also the holder of each of the Securities included in the Unit.  Thus, the holder of a Unit will have the rights and obligations of a holder of each included Security.  The unit agreement, if any, under which a Unit is issued may provide that the Securities included in the Unit may not be held or transferred separately, at any time or at any time before a specified date.

The particular terms and provisions of Units offered by any Prospectus Supplement, and the extent to which the general terms and provisions described below may apply thereto, will be described in the Prospectus Supplement filed in respect of such Units. This description will include, where applicable:

•the number of Units offered;

•the price or prices, if any, at which the Units will be issued;

•the currency at which the Units will be offered;

•the Securities comprising the Units;

•whether the Units will be issued with any other Securities and, if so, the amount and terms of these Securities;

•any minimum or maximum subscription amount;

•whether the Units and the Securities comprising the Units are to be issued in registered form, "book-entry only" form, non-certificated inventory system form, bearer form or in the form of temporary or permanent global securities and the basis of exchange, transfer and ownership thereof;

•any material risk factors relating to such Units or the Securities comprising the Units;

•any other rights, privileges, restrictions and conditions attaching to the Units or the Securities comprising the Units; and

•any other material terms or conditions of the Units or the Securities comprising the Units, including whether and under what circumstances the Securities comprising the Units may be held or transferred separately.

35

The terms and provisions of any Units offered under a Prospectus Supplement may differ from the terms described above, and may not be subject to or contain any or all of the terms described above.

RISK FACTORS

Before making an investment decision to purchase any Securities, investors should carefully consider the information described in this Prospectus and the documents incorporated or deemed incorporated by reference herein, including the applicable Prospectus Supplement.  There are certain risks inherent in an investment in the Securities, including the factors described in the 2022 AIF and the 2022 Annual MD&A and any other risk factors described in a document incorporated or deemed incorporated by reference herein, which investors should carefully consider before investing.  Additional risk factors relating to a specific offering of Securities will be described in the applicable Prospectus Supplement.  Some of the factors described in the documents incorporated or deemed incorporated by reference herein, and/or the applicable Prospectus Supplement are interrelated and, consequently, investors should treat such risk factors as a whole.  Additionally, purchasers should consider the risk factors set forth below.

If any of the adverse effects set out below or in the risk factors described in the 2022 AIF, in the 2022 Annual MD&A, in another document incorporated or deemed incorporated by reference herein or in the applicable Prospectus Supplement occur, it could have a material adverse effect on the business, financial condition and results of operations of the Company.  Additional risks and uncertainties of which the Company currently is unaware or that are unknown or that it currently deems to be immaterial could have a material adverse effect on the Company's business, financial condition and results of operations.  The Company cannot assure you that it will successfully address any or all of these risks.  There is no assurance that any risk management steps taken will avoid future loss due to the occurrence of the adverse effects set out below or in the risk factors in the 2022 AIF, in the 2022 Annual MD&A, in the other documents incorporated or deemed incorporated by reference herein or in the applicable Prospectus Supplement or other unforeseen risks.

In addition, we face the following risk factors in connection with future offerings of our Securities and risks in connection with our being a Canadian company:

Risks Related to Future Offerings

Use of Proceeds

While information regarding the use of proceeds from the sale the Securities will be described in the applicable Prospectus Supplement, the Company will have broad discretion over the use of the net proceeds from an offering of Securities. Because of the number and variability of factors that will determine the use of such proceeds, the Company's ultimate use might vary substantially from its planned use. Purchasers of Securities may not agree with how the Company allocates or spends the proceeds from an offering of Securities. The Company may pursue acquisitions, collaborations or other opportunities that do not result in an increase in the market value of our Securities, including the market value of the Common Shares, and that may increase our losses.

36

Return on Investment is not Guaranteed

There is no government or other guarantee that an investment in the Securities described herein will provide any positive return in the short term or long term. An investment in the Securities of the Company is speculative and involves a high degree of risk and should be undertaken only by investors whose financial resources are sufficient to enable them to assume such risks and who have no need for immediate liquidity in their investment. An investment in the securities of the Company described herein is appropriate only for holders who have the capacity to absorb a loss of some or all of their investment.

No Certainty of a Trading Market (other than for Common Shares)

There is currently no market through which the Securities (other than Common Shares) may be sold and purchasers of such Securities may not be able to resell such Securities purchased under a Prospectus Supplement to this Prospectus. Unless otherwise provided in such Prospectus Supplement, there can be no assurance that an active trading market will develop for such Securities after an offering or, if developed, that such market will be sustained. This may affect the pricing of such Securities in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation. The public offering prices of the Securities may be determined by negotiation between the Company and underwriters based on several factors and may bear no relationship to the prices at which the Securities will trade in the public market subsequent to such offering. See "Plan of Distribution".

Future Sales May Affect the Market Price of the Company Shares.

In order to finance future operations, the Company will need to raise funds through the issuance of either additional Common Shares or the issuance of debt instruments or other securities which may or may not be convertible into Common Shares.  The Company cannot predict the size of future issuances of Common Shares or the issuance of debt instruments or other securities convertible into Common Shares or the dilutive effect, if any, that future issuances and sales of the Company's securities will have on the market price of the Common Shares.  These sales may have an adverse impact on the market price of the Common Shares.

Multiple listings on the TSX, NYSE American and LSE may lead to an inefficient market in the Company's shares.

Multiple listing of the Common Shares will result in differences in liquidity, settlement and clearing systems, trading currencies, prices and transaction costs between the exchanges where the Common Shares will be quoted. These and other factors may hinder the transferability of the Common Shares between the three exchanges.

37

The Common Shares are quoted on TSX, NYSE American, and the LSE. Consequently, the trading in and liquidity of the Common Shares will be split between these three exchanges. The price of the Common Shares may fluctuate and may at any time be different on the TSX, the NYSE American and the LSE. This could adversely affect the trading of the Common Shares on these exchanges and increase their price volatility and/or adversely affect the price and liquidity of the Common Shares on these exchanges. The Common Shares are quoted and traded in Canadian Dollars on the TSX, in US Dollars on the NYSE American, and in pounds sterling on the LSE. The market price of the Common Shares on those exchanges may also differ due to exchange rate fluctuations.

There is no assurance that we will pay dividends in the future.

We have not paid any dividends on our Common Shares to date.  Payment of any future dividends, if any, will be at the discretion of our board of directors after taking into account many factors, including our operating results, financial condition, and current and anticipated cash needs.  Accordingly, there is no assurance that we will pay any future dividends on our Common Shares.

Risks Related to the Company being a Canadian Company

The Company is a Canadian company and shareholder protections differ from shareholder protections in the United States and elsewhere.

We are organized and exist under the laws of British Columbia, Canada and, accordingly, are governed by the BCBCA.  The BCBCA differs in certain material respects from laws generally applicable to United States corporations and shareholders, including the provisions relating to interested directors, mergers and similar arrangements, takeovers, shareholders' suits, indemnification of directors and inspection of corporation records.

The Company is a foreign private issuer within the meaning of the rules under the Exchange Act, and as such is exempt from certain provisions applicable to United States domestic public companies.

Because we are a "foreign private issuer" under the U.S. Exchange Act, we are exempt from certain provisions of the securities rules and regulations in the United States that are applicable to U.S. domestic issuers, including:

• the rules under the U.S. Exchange Act requiring the filing of quarterly reports on Form 10-Q or current reports on Form 8-K with the SEC;

• the sections of the U.S. Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security registered under the U.S. Exchange Act;

• the sections of the U.S. Exchange Act requiring insiders to file public reports of their stock ownership and trading activities and liability for insiders who profit from trades made in a short period of time; and

• the selective disclosure rules by issuers of material non-public information under Regulation FD.

We are required to file an annual report on Form 40-F with the United States Securities and Exchange Commission within three months of the end of each fiscal year.  We do not intend to voluntarily file annual reports on Form 10-K and quarterly reports on Form 10-Q in lieu of Form 40-F requirements.  For so long as we choose to only comply with foreign private issuer requirements, the information we are required to file with or furnish to the SEC will be less extensive and less timely compared to that required to be filed with the SEC by U.S. domestic issuers.  As a result, you may not be afforded the same protections or information which would be made available to you if you were investing in a U.S. domestic issuer.

38

CERTAIN INCOME TAX CONSIDERATIONS

The applicable Prospectus Supplement will describe certain Canadian federal income tax consequences to investors described therein of acquiring Securities.

ENFORCEABILITY OF CIVIL LIABILITIES BY U.S. INVESTORS

The Company is a corporation existing under the Business Corporations Act (British Columbia).  All but two of our directors, all of our officers, and all of the experts named in the Prospectus, are residents of Canada or otherwise reside outside the United States, and all or a substantial portion of their assets, and a majority of our assets, are located outside the United States.  We have appointed an agent for service of process in the United States, but it may be difficult for holders of the Securities who reside in the United States to effect service within the United States upon those directors, officers and experts who are not residents of the United States.  It may also be difficult for holders of the Securities who reside in the United States to realize upon judgments of courts of the United States predicated upon the Company's civil liability and the civil liability of its directors, officers and experts under the United States federal securities laws.

We have been advised by our Canadian legal counsel, McMillan LLP, that a judgment of a United States court predicated solely upon civil liability under United States federal securities laws would probably be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes.  We have also been advised by McMillan LLP, however, that there is substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon United States federal securities laws.

We have filed with the SEC, concurrently with our registration statement on Form F-10, an appointment of agent for service of process on Form F-X. Under the Form F-X, we appointed our subsidiary Florence Copper LLC as our agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against or involving the Company in a United States court arising out of, related to, or concerning the offering of the Securities under the Prospectus.

CONTRACTUAL RIGHTS OF RESCISSION

In addition to statutory rights of withdrawal and rescission, original purchasers of warrants (if offered separately from other Securities) and Subscription Receipts will have a contractual right of rescission against the Company in respect of the exercise of such warrant or subscription receipt, as the case may be.

The contractual right of rescission will entitle such original purchasers to receive, in addition to the amount paid on original purchase of the warrant or subscription receipt (or units comprised partly thereof), as the case may be, the amount paid upon exercise upon surrender of the underlying securities gained thereby, in the event that this prospectus (as supplemented or amended) contains a misrepresentation, provided that: (i) the conversion, exchange or exercise takes place within 180 days of the date of the purchase of the warrant or subscription receipt under this prospectus; and (ii) the right of rescission is exercised within 180 days of the date of purchase of the warrant or subscription receipt under this prospectus.  This contractual right of rescission will be consistent with the statutory right of rescission described under section 131 of the Securities Act (British Columbia), and is in addition to any other right or remedy available to original purchasers under section 131 of the Securities Act (British Columbia) or otherwise at law.

41

Original purchasers are further advised that in certain provinces and territories the statutory right of action for damages in connection with a prospectus misrepresentation is limited to the amount paid for the security that was purchased under a prospectus, and therefore a further payment at the time of exercise may not be recoverable in a statutory action for damages.  The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province for the particulars of these rights, or consult with a legal advisor.
