LITHIUM AMERICAS CORP.

US$350,000,002

15,909,091 Common Shares at a price of US$22.00 per Common Share

This prospectus supplement (the "prospectus supplement") of Lithium Americas Corp. ("LAC", "we" or the "Company"), together with the accompanying short form base shelf prospectus to which this prospectus supplement relates dated October 19, 2020 (the "prospectus"), qualifies the distribution of 15,909,091 common shares (the "Offered Shares") of the Company at a price of US$22.00 per Offered Share (the “Offering Price”), for aggregate gross proceeds of approximately US$350,000,000 (the “Offering”). The Offering is being made pursuant to an underwriting agreement (the “Underwriting Agreement”) dated January 20, 2021 among the Company, Canaccord Genuity LLC (the “Lead Underwriter”), Deutsche Bank Securities Inc. (“Deutsche Bank”), Evercore Group L.L.C., (“Evercore”), Stifel, Nicolaus & Company, Incorporated (“Stifel”), National Bank Financial Inc. (“National Bank”) and Cormark Securities Inc. (“Cormark” and together with the Lead Underwriter, Deutsche Bank, Evercore, Stifel and National Bank, the “Underwriters”). Deutsche Bank and Evercore are not registered as investment dealers in any Canadian jurisdiction for the purposes of the Offering and, accordingly, Deutsche Bank and Evercore will not offer and sell the Offered Shares in Canada. Any sales in Canada by the Lead Underwriter will be made through its affiliate, Canaccord Genuity Corp. The Offering Price was determined by arm’s length negotiation between the Company and the Lead Underwriter, on behalf of the Underwriters.  See “Plan of Distribution”.

The outstanding common shares of the Company (the “Common Shares”) are listed and posted for trading on the Toronto Stock Exchange (the "TSX") under the symbol "LAC" and on the New York Stock Exchange (the "NYSE") under the symbol "LAC". On January 19, 2021, the last trading day before the date of this prospectus supplement on the TSX and NYSE, the closing prices of the Common Shares on such exchanges were C$34.06 and US$26.82, respectively. The Company has applied to list the Offered Shares for trading on the TSX and the NYSE.  The TSX and NYSE have not conditionally approved the Company’s listing applications and there is no assurance that the TSX or NYSE will approve the listing applications. The listing of the Offered Shares will be subject to the Company fulfilling all of the requirements of the TSX and the NYSE, respectively.

We are permitted, under the multi-jurisdictional disclosure system adopted by the securities regulatory authorities in the United States and Canada (the "MJDS"), to prepare this prospectus supplement and the accompanying prospectus in accordance with Canadian disclosure requirements, which are different from United States disclosure requirements. We prepare our annual financial statements, certain of which are incorporated by reference herein, in United States dollars and in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board (the "IASB"), and our interim financial statements, certain of which are incorporated by reference herein, in United States dollars and in accordance with IFRS as issued by the IASB as applicable to interim financial reporting, and they therefore may not be comparable to financial statements of United States companies.

NEITHER THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION (THE "SEC") NOR ANY STATE SECURITIES COMMISSION OR REGULATOR HAS APPROVED OR DISAPPROVED THE OFFERED SHARES, NOR PASSED UPON THE ADEQUACY OR ACCURACY OF THE PROSPECTUS OR THIS PROSPECTUS SUPPLEMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.‎

Notes:

(1)Pursuant to the Underwriting Agreement, the Company has agreed to pay the Underwriters a cash fee (the "Underwriters' Fee") equal to 5.5% of the aggregate gross proceeds of the Offering. See "Plan of Distribution". 

(2)After deducting the Underwriters' Fee, but before deducting expenses of the Offering estimated to be an aggregate of US$1,000,000, which will be paid from the proceeds of the Offering.

(3)Amounts are rounded to the nearest $10. 

(4)If the Over-Allotment Option (as defined herein) is exercised in full, the gross proceeds of the Offering, Underwriters' Fee and net proceeds to the Company (before deducting expenses of the Offering) will be approximately US$400,000,000, approximately US$22,000,000 and approximately US$378,000,000 respectively. This prospectus supplement and accompanying prospectus also qualify for distribution the Over-Allotment Option and the Over-Allotment Shares (as defined herein) issued pursuant to the exercise of the Over-Allotment Option. See "Plan of Distribution".

The Company has also granted to the Underwriters an option (the "Over-Allotment Option") exercisable, in whole or in part and from time to time, at the sole discretion of the Underwriters, at any time up to 30 days following the closing of the Offering, to purchase up to an additional 2,272,727 Offered Shares ("Over-Allotment Shares") at the Offering Price to cover over-allotments, if any, and for market stabilization purposes. A purchaser who acquires Over-Allotment Shares forming part of the Underwriters' over-allocation position acquires those Over-Allotment Shares under this prospectus supplement, regardless of whether the over-allocation position is ultimately filled through the exercise of the Over-Allotment Option or secondary market purchases. Unless the context otherwise requires, references in this prospectus supplement and the accompanying prospectus to "Offered Shares" include any Over-Allotment Shares issued pursuant to the Over-Allotment Option.

The following table sets out the number of securities issuable under the Over-Allotment Option:

Underwriters' Position	Maximum size or number of securities available	Exercise period	Exercise price
Over-Allotment Option	2,272,727 Common Shares	30 days following closing of the Offering	US$22.00 per Common Share

The Underwriters, as principals, conditionally offer the Offered Shares, subject to prior sale, if, as and when issued by the Company and accepted by the Underwriters in accordance with the conditions contained in the Underwriting Agreement and subject to the passing upon of certain legal matters relating to the Offering on behalf of the Company by Cassels Brock & Blackwell LLP with respect to Canadian legal matters and by Dorsey & Whitney LLP with respect to United States legal matters, and on behalf of the Underwriters by Blake, Cassels & Graydon LLP with respect to certain Canadian legal matters, and Skadden, Arps, Slate, Meagher & Flom LLP with respect to certain United States legal matters.

The Underwriters propose to offer the Offered Shares to the public initially at the price specified on the cover page of this prospectus supplement. If all of the Offered Shares are not sold at the price specified in this prospectus supplement, the Underwriters may decrease the offering price and change the other selling terms. The compensation realized by the Underwriters will decrease by the amount that the aggregate offering price paid by the purchasers for the Offered Shares is less than the gross proceeds paid by the Underwriters to the Company. The decrease in the offering price will not decrease the amount of net proceeds of the Offering to the Company. See ''Plan of Distribution''.

Subscriptions will be received subject to rejection or allotment in whole or in part and the right is reserved to close the subscription books at any time without notice. Closing is expected to occur on or about January 22, 2021, or such other date as may be agreed upon by the Company and the Lead Underwriter (the "Closing Date"). It is expected that the Company will arrange for the electronic deposit of the Offered Shares distributed under the Offering under the book-based system of registration, to be registered in the name of CDS Clearing and Depository Services Inc. ("CDS") or its nominee and will be deposited with CDS on the Closing Date. No certificates evidencing the Offered Shares will be issued to purchasers of the Offered Shares, except in limited circumstances. Purchasers of Offered Shares will receive only a customer confirmation from the Underwriters or other registered dealers from whom the Offered Shares are purchased. See "Plan of Distribution".

- iii -

The Underwriters may, in connection with the Offering, effect transactions which stabilize or maintain the market price of the Common Shares at levels other than those which might otherwise prevail in the open market in accordance with applicable market stabilization rules.  Such transactions, if commenced, may discontinue at any time. See "Plan of Distribution".

Purchasers of the Offered Shares should be aware that the acquisition 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. Purchasers of the Offered Shares should read the tax discussion contained in this prospectus supplement and consult their own tax advisors. See "Certain Canadian Federal Income Tax Considerations" and "Certain United States Federal Income Tax Considerations".

The enforcement by investors of civil liabilities under United States federal securities laws may be affected adversely by the fact ‎that the Company is incorporated under the laws of British Columbia, a province of Canada, certain of the officers and directors are not residents of the United ‎States, that some or all of the Underwriters or experts named in this prospectus supplement and in the accompanying prospectus are ‎not residents of the United States, and that certain of the Company's assets and all or a substantial portion of the assets of such persons are located outside of the United States. See "Enforceability of Certain Civil Liabilities".‎

Investing in the Offered Shares is highly speculative and involves significant risks that you should consider before purchasing the Offered Shares. The risks outlined in this prospectus supplement, the accompanying prospectus and in the documents incorporated by reference herein and therein should all be carefully reviewed and considered. See "Risk Factors".

Certain of our directors and officers and some of the experts named in this prospectus supplement and the accompanying prospectus reside outside of Canada. See "Enforceability of Certain Civil Liabilities and Agent for Service of Process" in the prospectus accompanying this prospectus supplement.

The Company's head and registered office is located at 300-900 West Hastings Street, Vancouver, British Columbia, Canada, V6C 1E5.

Unless otherwise indicated, all references in this prospectus supplement and the accompanying prospectus to "$" or "US$" are to United States dollars, and references to "C$" are to Canadian dollars. See "Currency and Exchange Rate Information".

ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of the Offered Shares being offered and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference herein and therein. The second part, the 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 accompanying prospectus solely for the purposes of the Offering constituted by this prospectus supplement.

You should rely only on the information contained in or incorporated by reference in this prospectus supplement and the accompanying prospectus and on the other information included in the Company's registration statement (the "Registration Statement") on Form F-10 (File No. 333-249078), as amended, filed with the SEC, of which this prospectus supplement and the accompanying prospectus form a part. If the description of the Offered Shares or any other information varies between this prospectus supplement and the accompanying prospectus (including the documents incorporated by reference herein and therein), you should rely on the information in this prospectus supplement. We have not, and the Underwriters have not, authorized anyone to provide you with different or additional information. If anyone provides you with different or additional information, you should not rely on it. The Company and the Underwriters are not making an offer to sell or seeking an offer to buy the Offered Shares in any jurisdiction where the offer or sale is not permitted.  You should not assume that the information contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein is accurate as of any date other than the date on the front of this prospectus supplement, the accompanying prospectus or the respective dates of the documents incorporated by reference herein and therein, as applicable, regardless of the time of delivery of this prospectus supplement or of any sale of the Offered Shares pursuant hereto. Our business, financial condition, results of operations and prospects may have changed since those dates. Information contained on the Company's website should not be deemed to be a part of this prospectus supplement, the accompanying prospectus or incorporated by reference herein or therein and should not be relied upon by a prospective investor for the purpose of determining whether to invest in the Offered Shares.

Market data and certain industry forecasts used in the prospectus and this prospectus supplement and the documents incorporated ‎by reference in the prospectus and this prospectus supplement were obtained from market research, publicly available information ‎and industry publications. We believe that these sources are generally reliable, but the accuracy and completeness of this information ‎is not guaranteed. We have not independently verified such information, nor have we ascertained the validity or accuracy of the underlying economic assumptions relied upon therein, and we do not make any representation as to the accuracy ‎of such information.

This prospectus supplement shall not be used by anyone for any purpose other than in connection with the Offering.

Unless we have indicated otherwise, or the context otherwise requires, references in this prospectus supplement or the accompanying prospectus to "LAC", the "Company", "we", "us" and "our" refer to Lithium Americas Corp. and/or, as applicable, one or more of its subsidiaries and/or, as applicable, its joint venture.

FORWARD-LOOKING INFORMATION

This prospectus supplement and the accompanying prospectus, including the documents incorporated by reference, contain "forward-looking information" within the meaning of applicable Canadian securities legislation and "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 (collectively referred to herein as "forward-looking information"). These statements relate to future events or the Company's future performance. All statements, other than statements of historical fact, may be forward-looking information. Information concerning mineral resource and mineral reserve estimates also may be deemed to be forward-looking information in that it reflects a prediction of mineralization that would be encountered if a mineral deposit were developed and mined. Forward-looking information generally can be identified by the use of words such as "seek", "anticipate", "plan", "continue", "estimate", "expect", "may", "will", "project", "predict", "propose", "potential", "targeting", "intend", "could", "might", "should", "believe" and similar expressions. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking information.

In particular, this prospectus supplement and the accompanying prospectus contain or incorporate by reference forward-looking information, including, without limitation, with respect to the following matters or the Company's expectations relating to such matters: successful development of the Cauchari-Olaroz and Thacker Pass Projects (each as defined in the accompanying prospectus), including timing, progress, construction, milestones, anticipated productions and results thereof; the expected benefits from the Project Investment (as defined in the accompanying prospectus); the expected benefits from the 2020 Cauchari Transaction (as defined in the accompanying prospectus); expectations and anticipated impact of any COVID-19 (as defined in the accompanying prospectus) cases on site; statements regarding anticipated decision making with respect to Minera Exar (as defined in the accompanying prospectus); capital expenditures and programs; estimates of the mineral resources and mineral reserves at the Company's properties; development of mineral resources and mineral reserves; government regulation of mining operations and treatment under governmental and taxation regimes; the future price of commodities, including lithium; the realization of mineral resources and mineral reserves estimates, including whether mineral resources will ever be developed into mineral reserves and information and underlying assumptions related thereto; the timing and amount of future production; currency exchange and interest rates; expected outcome and timing of environmental surveys and permit applications and other environmental matters; the Company's ability to raise capital; expected expenditures to be made by the Company on its properties; the timing, cost, quantity, capacity and product quality of production of the Cauchari-Olaroz Project, which is held and operated through the Company's joint venture with Ganfeng (as defined in the accompanying prospectus); successful operation of the Cauchari-Olaroz Project under its co-ownership structure; whether the Company will ever be able to realize on the additional debt funding commitment from Bangchak (as defined in the accompanying prospectus), including the terms and timing thereof; ability to produce high quality battery grade lithium carbonate; the timing, cost, quantity, capacity and product quality of production at the Thacker Pass Project; results of the Company's engineering, design, permitting program at the Thacker Pass Project, including that the Company meets deadlines and receives permits as anticipated; successful results from the Company's testing facility and third-party tests related thereto; capital costs, operating costs, sustaining capital requirements, after tax net present value and internal rate of return, payback period, sensitivity analyses, net cash flows and EBITDA (as defined in the accompanying prospectus) of the Cauchari-Olaroz Project and the Thacker Pass Project; timing, results and completion of the Thacker Pass Project feasibility study; the Company's share of the expected capital expenditures for the construction of the Cauchari-Olaroz Project and for permitting and Thacker Pass Project feasibility study activities at the Thacker Pass Project; ability to achieve capital cost efficiencies; stability and inflation related to the Argentine peso, whether the Argentine government implements additional foreign exchange and capital controls, and the effect of current or any additional regulations on the Company's operations; approval of pending patents; and the potential for partnership and financing scenarios for the Thacker Pass Project.

S-2

Forward-looking information does not take into account the effect of transactions or other items announced or occurring after the statements are made. Forward-looking information is based upon a number of expectations and assumptions and is subject to a number of risks and uncertainties, many of which are beyond the Company's control, that could cause actual results to differ materially from those that are disclosed in or implied by such forward-looking information. With respect to forward-looking information listed above and incorporated by reference herein, the Company has made assumptions regarding, among other things:

• current technological trends;

• a cordial business relationship between the Company and Ganfeng for the Cauchari-Olaroz Project;

• ability of the Company to fund, advance and develop the Cauchari-Olaroz Project and the Thacker Pass Project, and the respective impacts of the projects when production commences;

• the Company's ability to operate in a safe and effective manner;

• uncertainties relating to receiving and maintaining mining, exploration, environmental and other permits or approvals in Nevada and Argentina;

• demand for lithium, including that such demand is supported by growth in the electric vehicle market;

• the impact of increasing competition in the lithium business, and LAC's competitive position in the industry;

• general economic conditions;

• the stable and supportive legislative, regulatory and community environment in the jurisdictions where the Company operates;

• stability and inflation of the Argentinian peso, including any foreign exchange or capital controls which may be enacted in respect thereof, and the effect of current or any additional regulations on the Company's operations;

• the impact of unknown financial contingencies, including litigation costs, on the Company's operations;

• gains or losses, in each case, if any, from short-term investments in Argentine bonds and equities;

• estimates of and unpredictable changes to the market prices for lithium;

• exploration, development and construction costs for the Cauchari-Olaroz Project and the Thacker Pass Project;

• estimates of mineral resources and mineral reserves, including whether mineral resources will ever be developed into mineral reserves;

• reliability of technical data;

S-3

• anticipated timing and results of exploration, development and construction activities, including the impact of COVID-19 on such timing;

• timely responses from governmental agencies responsible for reviewing and considering the Company's permitting activities at the Thacker Pass Project;

• the Company's ability to obtain additional financing, including pursuant to the additional debt funding commitment from Bangchak, on satisfactory terms or at all;

• the ability to develop and achieve production at any of the Company's mineral exploration and development properties;

• the impact of COVID-19 on the Company's business;

• expected benefits from the 2020 Cauchari Transaction;

• accuracy of development budget and construction estimates; and

• preparation of a development plan for lithium production at the Thacker Pass Project.

Although the Company believes that the assumptions and expectations reflected in such forward-looking information are reasonable, LAC can give no assurance that these assumptions and expectations will prove to be correct, and since forward-looking information inherently involves risks and uncertainties, undue reliance should not be placed on such information.

The Company's actual results could differ materially from those anticipated in any forward-looking information as a result of the risk factors contained in and incorporated by reference in this prospectus supplement, including but not limited to, the factors referred to under the heading "Risk Factors" in this prospectus supplement, under the heading "Description of the Business - Risk Factors" in the Company's most recent annual information form and under the heading "Risks and Uncertainties" in the Company's management's discussion and analysis for our most recently completed audited financial year and, if applicable, interim financial period. Such risks include, but are not limited to the following: the impacts of COVID-19 on the availability and movement of personnel, supplies and equipment and on the timing for regulatory approvals and permits and on third parties on whom the Company or the joint venture operation in respect of the Cauchari-Olaroz Project rely for services, such as preparation of the Thacker Pass definitive feasibility study and construction at the Cauchari-Olaroz Project; the Company's mineral properties may not be developed as planned and uncertainty of whether there will ever be production at the Company's mineral exploration properties; cost overruns; risks associated with the Company's ability to successfully secure adequate funding; market prices affecting the ability to develop the Company's mineral properties; risks associated with co-ownership arrangements; risk to the growth of lithium markets; lithium prices; inability to obtain required governmental permits and government-imposed limitations on operations; technology risk; inability to achieve and manage expected growth; political risk associated with foreign operations, including co-ownership arrangements with foreign domiciled partners; emerging and developing market risks; risks associated with not having production experience; operational risks; changes in government regulations; risks associated with proposed tax changes in Nevada that could increase the costs of our operations; changes to environmental requirements; failure to obtain or maintain necessary licenses, permits or approvals; insurance risk; receipt and security of mineral property titles and mineral tenure risk; changes in project parameters as plans continue to be refined; changes in legislation, governmental or community policy; mining industry competition; market risk; volatility in global financial conditions; uncertainties associated with estimating mineral resources and mineral reserves, including uncertainties relating to the assumptions underlying mineral resource and mineral reserve estimates; whether mineral resources will ever be converted into mineral reserves; whether the Company is able to successfully monetize any increase in off-take from any increased development plan, and the expected benefits from the Project Investment and other transactions described herein and in the prospectus and in the documents incorporated by reference herein and therein; the expected benefits from the 2020 Cauchari Transaction; inherent risks in realizing on Bangchak's additional debt funding commitment, including the availability thereof, consent of the Company's senior lenders and the addition of additional debt on the Company's balance sheet; risks related to investments in Argentine bonds and equities; opposition to development of the Company's mineral properties; lack of unitization and reservoir management rules; surface access risk; geological, technical, drilling or processing problems; uncertainties in estimating capital and operating costs, cash flows and other project economics; liabilities and risks, including environmental liabilities and risks inherent in mineral extraction operations; health and safety risks; risks related to the stability and inflation of the Argentine peso, including any foreign exchange or capital controls which may be enacted in respect thereof, and the effect of current and any additional regulations on the Company's operations; risks related to unknown financial contingencies, including litigation costs, on the Company's operations; incorrect assessments of the value of acquisitions; unanticipated results of exploration activities; unpredictable weather conditions; unanticipated delays in preparing technical studies; inability to generate profitable operations; restrictive covenants in debt instruments; lack of availability of additional financing on terms acceptable to the Company and/or joint venture partners; shareholder dilution; intellectual property risk; dependency on key personnel; payment of dividends; competition for, amongst other things, capital, undeveloped lands and skilled personnel; fluctuations in currency exchange and interest rates; regulatory risk, including as a result of the Company's dual-exchange listing and increased costs thereof; conflicts of interest; Common Share price volatility; and cyber-security risks and threats. Consequently, actual results and events may vary significantly from those included in, contemplated or implied by such statements.

S-4

Readers are cautioned that the foregoing lists of factors are not exhaustive. The forward-looking information contained in or incorporated by reference in this prospectus supplement is expressly qualified by these cautionary statements. All forward-looking information in this prospectus supplement speaks as of the date of this prospectus supplement. The Company does not undertake any obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, except as required by law. All forward-looking information contained in this prospectus supplement, and the accompanying prospectus, including the documents incorporated by reference herein and therein are expressly qualified in their entirety by this cautionary statement.  Additional information about these assumptions and risks and uncertainties is contained in the Company's filings with securities regulators, including the Company's most recent annual information form and most recent management's discussion and analysis for our most recently completed financial year and, if applicable, interim financial period, which are available on SEDAR at www.sedar.com and EDGAR at www.sec.gov. 

CAUTIONARY NOTE FOR UNITED STATES INVESTORS

We are permitted under the MJDS to prepare this prospectus supplement and the accompanying prospectus in accordance with Canadian disclosure requirements, which are different from United States disclosure requirements. We prepare our annual financial statements, certain of which are incorporated by reference herein, in United States dollars and in accordance with IFRS as issued by the IASB, and our interim financial statements, certain of which are incorporated by reference herein, in United States dollars and in accordance with IFRS as issued by the IASB as applicable to interim financial reporting, and they therefore may not be comparable to financial statements of United States companies.

The disclosure included in or incorporated by reference in this prospectus supplement uses mineral reserves and mineral resources classification terms that comply with reporting standards in Canada and are made in accordance with 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.

These standards differ significantly from the requirements of the SEC that are applicable to domestic United States reporting companies. Any mineral reserves and mineral resources reported by the Company in accordance with NI 43-101 may not qualify as such under SEC standards. Accordingly, information included in this prospectus supplement and the documents incorporated by reference herein that describes the Company's mineral reserves and mineral resources estimates may not be comparable with information made public by United States companies subject to the SEC's reporting and disclosure requirements.

PRESENTATION OF FINANCIAL INFORMATION

We present our financial statements in United States dollars and our annual financial statements are prepared in accordance with IFRS as issued by the IASB and our interim financial statements are prepared in accordance with IFRS as issued by the IASB as applicable to interim financial reporting. As a result, certain financial information included in or incorporated by reference in this prospectus supplement may not be comparable to financial information prepared by companies in the United States reporting under US GAAP. Certain calculations included in tables and other figures in this prospectus supplement have been rounded for clarity of presentation.

CURRENCY AND EXCHANGE RATE INFORMATION

This prospectus supplement and the accompanying prospectus contain references to United States dollars and Canadian dollars. Unless otherwise indicated, all references in this prospectus supplement and the accompanying prospectus to "$" or "US$" are to United States dollars, and references to "C$" are to Canadian dollars. The following table sets forth, for each of the periods indicated, the high, low and average exchange rates, and the exchange rate at the end of the period, for the conversion of one (1) United States dollar into the Canadian dollar equivalent, based on the indicative exchange rate as reported by the Bank of Canada:

High	C$1.4496	C$1.3600	C$1.4496	C$1.3600

RISK FACTORS

Investing in the Offered Shares is speculative and involves a high degree of risk due to the nature of our business and the present ‎stage of our development. Before deciding to invest in the Offered Shares, you should carefully consider all of the information contained in, and incorporated or deemed to be incorporated by reference in, this prospectus supplement and the accompanying prospectus. An investment in the Offered Shares is subject to certain risks, including risks related to the business of the Company, risks related to mining operations and risks related to the Company's securities described in the prospectus and the documents incorporated or deemed to be incorporated by reference in the prospectus and herein by reference. SEE THE RISK FACTORS BELOW AND THE "RISK FACTORS" SECTION OF THE ACCOMPANYING PROSPECTUS AND THE DOCUMENTS INCORPORATED OR DEEMED TO BE INCORPORATED BY REFERENCE HEREIN AND THEREIN. Each of the risks described in these sections and in the documents incorporated by reference herein could materially and adversely ‎affect our business, financial condition, results of operations and prospects, could cause them to differ materially from the estimates ‎described in forward-looking statements relating to the Company, or its business, properties or financial performance, and could result in an entire ‎loss of your investment. These risks are not the only risks we face. Additional risks and uncertainties not known to us or that we ‎currently deem immaterial may also impair our business, financial condition, results of operations and prospects‎.

These risk factors, together with all other information included or incorporated by reference in this prospectus supplement and accompanying prospectus, including, without limitation, information contained in the section "Cautionary Note Regarding Forward-Looking Statements" as well as the risk factors in the accompanying prospectus and the documents incorporated by reference, should be carefully reviewed and considered by investors. Some of the factors described herein and the accompanying prospectus, in the documents incorporated or deemed incorporated by reference herein and therein are interrelated and, consequently, investors should treat such risk factors as a whole.

S-9

If any of the adverse effects set out in the risk factors described herein and the accompanying prospectus, or in another document incorporated or deemed incorporated by reference herein or therein 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 of 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 provide assurance 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 in the risk factors herein and the accompanying prospectus, or in the other documents incorporated or deemed incorporated by reference herein or therein, or other unforeseen risks.

COVID-19 has Negatively Affected and is Expected to Further Negatively Affect the Company

In March 2020, COVID-19 was characterized as a pandemic by the World Health Organization. Since December 2019, COVID-19 has spread globally with a high concentration of cases in regions in which the Company conducts its business operations, including the United States, Canada and Argentina. The spread of COVID-19 and resulting tight government controls and travel bans implemented around the world, such as declarations of states of emergency, business closures and re-openings, and manufacturing, commercial and/or other similar restrictions and limitations, have caused disruption to global supply chains and economic activity, and the market has entered a period of significantly increased volatility. Volatility and disruptions in the supply and demand for lithium and other metals and minerals, global supply chains and financial markets, as well as declining trade and market sentiment and reduced mobility of people, could affect commodity prices, interest rates, credit ratings, credit risk, share prices and inflation. On March 20, 2020, following the Presidential decree for mandatory social isolation in Argentina, construction of the Cauchari-Olaroz Project was temporarily suspended. Engineering, procurement and manufacturing of equipment, which was performed offsite, continued. In mid-April, in accordance with the governmental regulations allowing mining and construction activities to resume, the Cauchari-Olaroz Project gradually restarted construction activities, and increased the size of the camp, common areas and other infrastructure to accommodate social distancing by staff in accordance with established protocols. By the end of the second quarter of 2020, circulation of COVID-19 had intensified in the Province of Jujuy. In early July, as a result of workers at the project testing positive for COVID-19, construction was immediately suspended. During July, testing of the workforce at the project was completed, and workers were demobilized from the site. Only the minimum required staff remained on-site to oversee care and maintenance activities. All workers who tested positive in July have since recovered and have been released from isolation. Construction activities at the Cauchari-Olaroz Project resumed in August 2020 with enhanced COVID-19 protocols. The Company continues to work in close cooperation with the local communities, unions, its workforce and the Province of Jujuy, Argentina to maintain the safety of its operations and continually assess and refine its pandemic-related operating protocols. Overall, COVID-19 has impacted the development program for the Cauchari-Olaroz Project, including delays in delivery of equipment, limitations on operations as a result of government directives and internal operating protocols, the temporary suspension of operations in connection with onsite cases and the implementation of enhanced protocols to manage infections on site. There is a risk that these factors, along with other factors, related to COVID- 19 such as resurgences and mutations of the virus may continue to affect the Cauchari-Olaroz Project until the virus is brought under control in Argentina and globally. There is also a risk that the severity of some or all of these matters as they relate to the Cauchari-Olaroz Project may increase in the future.

Sustained disruption to development operations due to COVID-19, including future negative developments related to COVID-19 and governmental response to it, could have a material adverse effect on the Cauchari-Olaroz Project, including delays in the development timeline, an increase in development costs or a longer term suspension in the development of the project itself. There can be no assurance that a governmental directive similar to the Argentinian Presidential decree in March will not be issued in the future, that mining and construction activities will continue to be deemed essential businesses or that mining and construction activities will not otherwise be suspended in the future if COVID-19 continues to persist or there is a resurgence in Argentina, the United States, Canada or globally. The risks to the Company of COVID-19 also include restrictions, limitations and other effects on activities which may result in delays in obtaining requisite permitting for, completing a definitive feasibility study for and securing financing for the construction of the Thacker Pass Project and otherwise delay bringing the Thacker Pass Project to commercial production. Additional risks include the potential for the impairment of the Company's assets or write-downs in respect of the Company's material properties, or any part thereof, as a result of prolonged delays, limitations or restrictions on activities at the Company's properties due to COVID-19, risks to employee health and safety, increased costs and reductions to efficiencies, including those related to labour and fuel and any additional capital being required related to bringing the Company's projects to commercial production, supply chain disruptions, increases to insurance premiums, regulatory changes, political or economic instabilities, civil unrest and the availability of industry experts and personnel. The spread of COVID-19 is currently having an adverse impact on the global economy, the severity and duration of which are difficult to predict, and has adversely affected and may have further adverse effects on our performance, as well as our ability to successfully execute our operations, business strategies and initiatives. At this time, the full extent to which the COVID-19 pandemic will or may impact the Company remains uncertain and these factors are beyond the Company's control.

S-10

The Potential Impact of COVID-19 Continues to be Uncertain

COVID-19 and government responses to the pandemic have significantly impacted health and economic conditions throughout Canada, the United States, Argentina and globally. The global spread of COVID-19 has been, and continues to be, complex and rapidly evolving, with governments, public institutions and other organizations imposing or recommending, and businesses and individuals implementing, removing and reimplementing, restrictions on various activities or other actions to combat its spread and resurgence, such as travel restrictions and bans, social distancing, quarantine or shelter-in-place directives, limitations on the size of gatherings, and closures of non-essential businesses. These restrictions have disrupted and may continue to disrupt from time-to-time and for prolonged periods of time, economic activity, resulting in reduced commercial and consumer confidence and spending, increased unemployment, closure or restricted operating conditions for businesses, volatility in the global economy, instability in the credit and financial markets, labor shortages, regulatory recommendations to provide relief for impacted constituents, and disruption in supply chains.

The full extent to which COVID-19 impacts the Company's business, operations, financial position, results of operations and prospects is highly uncertain and will depend on numerous evolving factors that we may not be able to accurately predict or assess, including, but not limited to, the severity, extent and duration of the pandemic or any resurgences in the future, including any economic recession resulting from the pandemic, the availability of approved vaccines and the timing for completion of vaccine distribution programs around the globe, and the continued governmental, business and individual actions taken in response to the pandemic. Impacts related to COVID-19 are expected to continue to pose risks to the Company's business for the foreseeable future, may heighten many of the risks and uncertainties identified in this Prospectus, and could have a material adverse impact on the Company's business, operations, financial position, results of operations or prospects in a manner that is difficult to predict.

Discretion in the Use of Proceeds

The Company currently intends to allocate the net proceeds received from the Offering as described under "Use of Proceeds"; ‎however, the Company will have discretion in the actual application of such net proceeds, and may elect to allocate net proceeds ‎differently from that described under "Use of Proceeds" if determined by the Board to be in the Company's best interests to do so. ‎Shareholders may not agree with the manner in which the Board and management choose to allocate and spend the net proceeds. ‎The failure by the Company to apply these funds effectively could have a material adverse effect on the Company's business‎, financial condition, results of operations and prospects.

Loss of Entire Investment

An investment in the Offered Shares is speculative and may result in the loss of an investor's entire investment. Only potential investors who are experienced in high risk investments and who can afford to lose their entire investment should consider an investment in the Company‎.

Dilution from Further Financings

The Company may need to raise additional financing in the future, including through the issuance of additional equity securities or convertible debt securities. If the Company raises additional funding by issuing additional equity securities or convertible debt securities, such financings may substantially dilute the interests of shareholders of the Company and reduce the value of their investment and the value of the Company's securities.

CONSOLIDATED CAPITALIZATION

The following describes the changes in the consolidated capitalization of the Company since September 30, 2020, the date of the Company's most recent financial statements. Except as set forth below, there have been no material changes in the share and loan capital of the Company, on a consolidated basis, since September 30, 2020.

(a)As of November 30, 2020, the Company issued 9,266,587 Common Shares pursuant to ATM Program. See "The Company - Recent Developments - At-The Market Equity Program".

(b)During the period from October 1, 2020 up to and including January 18, 2021, the Company issued a total of 566,724 Common Shares pursuant to the Company's equity compensation plan upon exercise of stock options, restricted share units and deferred share units and received gross proceeds of C$1,937,450. 

S-11

As a result of the Offering, the shareholder's equity of the Company will increase by the amount of the net proceeds of the Offering and the number of issued and outstanding Common Shares will increase by the number of Offered Shares actually distributed under the Offering.

USE OF PROCEEDS

The net proceeds to the Company from the Offering, after deducting the Underwriters' Fee of approximately $19,250,000 but before deducting the expenses of the Offering (estimated to be approximately US$1,000,000), will be approximately US$330,750,000. If the Over-Allotment Option is exercised in full, the net proceeds from the Offering are estimated to be approximately US$378,000,000 after deducting the Underwriters' Fee but before deducting the estimated expenses relating to the Offering of approximately US$1,000,000. See "Plan of Distribution".

The Company intends to use the net proceeds from the Offering to advance the Thacker Pass Project, to satisfy obligations under the Senior Credit Facility, for general corporate purposes and for working capital. To date, the Company has not generated significant revenues from operations. The Company had negative operating cash flows for the year ended December 31, 2019 and for the nine months ended September 30, 2020 and the Company may continue to incur negative operating cash flows. As a result, the Company may need to allocate a portion of its existing working capital or a portion of the proceeds of the Offering to fund any such negative operating cash flow in future periods. The Company may, from time to time, issue securities (including equity and debt securities) other than pursuant to this prospectus supplement.

The net proceeds of the Offering are intended to be used as follows (assuming the Over-Allotment Option is not exercised):

Principal Purpose(1)	Estimated Amount to be Expended (US$)
Pre-construction and Engineering costs on Thacker Pass Project	US$23,200,000
Development Costs on Thacker Pass Project(2)	US$272,050,000
Interest Expense on Senior Credit Facility	US$20,000,000
General corporate and working capital purposes(3)	US$14,500,000
Total	US$329,750,000

_________________________________________

Notes:

(1)Expenditures are based on budgeted and forecasted costs over the course of 2021 and 2022, with the exception of the development costs at Thacker Pass, which may involve expenditures over a longer term depending on the development timetable established by the Company.

(2)A decision to incur expenditures on development of the Thacker Pass Project is subject to several factors, including results of the feasibility study work currently in progress, the extent and terms of third-party financing that the Company secures for development costs, if any, and the Company having made a development decision on the project.  The Company may, in its discretion, alternately elect to allocate all or a portion of these proceeds to repayment of amounts owing under the Senior Credit Facility and other liabilities and/or to general corporate purposes.

(3)Funds included in general corporate purposes may be allocated to corporate expenses, business development and other business opportunities.

If the Underwriters' Over-Allotment Option is exercised in whole or in part, the Company will use the additional net proceeds from such exercise for general corporate purposes and working capital.

Although the Company intends to expend the net proceeds from the Offering as set forth above, there may be circumstances where, for sound business reasons, a reallocation of funds may be prudent or necessary, and may vary materially from that set forth above. In addition, management of the Company will have broad discretion with respect to the actual use of the net proceeds from the Offering. See "Risk Factors".

The actual amount that the Company spends in connection with each of the intended uses of proceeds may vary significantly from the amounts specified above, and will depend on a number of factors, including those listed under the heading "Risk Factors" in this prospectus supplement and the accompanying prospectus and set out in the documents incorporated by reference herein and therein.

PLAN OF DISTRIBUTION

Subject to and pursuant to the Underwriting Agreement, the Company has agreed to sell and the Underwriters have severally, and not jointly nor jointly and severally, agreed to purchase on the Closing Date, a total of 15,909,091 Offered Shares at the Offering Price of US$22.00 per Offered Share, payable in cash to the Company against delivery of such Offered Shares, on the Closing Date.The Offering Price was determined by arm's length negotiation between the Company and the Lead Underwriter, on behalf of the Underwriters. Closing is expected to occur on or about January 22, 2021, or such other date as may be agreed upon by the Company and the Lead Underwriter.

S-12

In consideration for their services in connection with the Offering, the Underwriters will be paid the Underwriters' Fee equal to 5.5% of the gross proceeds of the Offering (US$1.21 per Offered Share, for an aggregate fee payable by the Company of approximately US$19,250,000, exclusive of the Over-Allotment Shares). The Company has agreed in the Underwriting Agreement to reimburse the Underwriters for their legal fees and certain other expenses in connection with the Offering. 

The obligations of the Underwriters under the Underwriting Agreement may be terminated at their discretion upon the occurrence of certain events specified in the Underwriting Agreement including standard "litigation out", "disaster out" "regulatory out", "material adverse change out", "market out", and "breach out" rights of termination. The Underwriters are, however, obligated to take up and pay for all of the Offered Shares if any of the Offered Shares are purchased under the Underwriting Agreement. The Underwriters, as principals, are conditionally offering the Offered Shares, subject to prior sale, if, as and when issued to and accepted by them, subject to certain conditions contained in the Underwriting Agreement.

Pursuant to the Underwriting Agreement, the Company has granted to the Underwriters the Over-Allotment Option, exercisable in whole or in part at any time up to 30 days after the Closing Date, to purchase the Over-Allotment Shares at the Offering Price to cover over-allotments, if any, and for market stabilization purposes, on the same terms and conditions as apply to the purchase of Offered Shares thereunder. This prospectus supplement qualifies for distribution the Offered Shares as well as the grant of the Over-Allotment Option and the issuance of the Over-Allotment Shares pursuant to the exercise of the Over-Allotment Option. A purchaser who acquires Over-Allotment Shares forming part of the Underwriters' over-allocation position acquires those Over-Allotment Shares under this prospectus supplement, regardless of whether the over-allocation position is ultimately filled through the exercise of the Over-Allotment Option or secondary market purchases.

The Offering is being made concurrently in all of the provinces and territories of Canada, except Québec, and in the United States pursuant to the MJDS. The Offered Shares will be offered in the United States and Canada by the Underwriters either directly or through their respective duly registered United States or Canadian broker-dealer affiliates or agents, as applicable. Subject to applicable law and the provisions of the Underwriting Agreement, the Underwriters may also offer the Offered Shares outside of Canada and the United States on a private placement or equivalent basis.

The Company has applied to list the Offered Shares on the TSX and the NYSE. The TSX and NYSE have not conditionally approved the Company's listing applications and there is no assurance that the TSX or NYSE will approve the listing applications. Listing will be subject to the Company fulfilling all of the listing requirements of the TSX and the NYSE. 

Pursuant to policies of certain Canadian securities regulatory authorities, the Underwriters may not, throughout the period of distribution under the Offering, bid for or purchase Common Shares for their own accounts or for accounts over which they exercise control or direction. The foregoing restriction is subject to certain exceptions, on the condition that the bid or purchase not be engaged in for the purpose of creating actual or apparent active trading in or raising the price of the Common Shares. These exceptions include a bid or purchase permitted under Universal Market Integrity Rules for Canadian marketplaces administered by the Investment Industry Regulatory Organization of Canada relating to market stabilization and passive market making activities, and a bid or purchase made for or on behalf of a customer where the order was not solicited during the period of distribution. Subject to the foregoing, the Underwriters may effect transactions which stabilize or maintain the market price of the Common Shares at levels other than those which otherwise might prevail on the open market. These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of preventing or mitigating a decline in the market price of the Common Shares, and may cause the price of the Offered Shares to be higher than would otherwise exist in the open market absent such stabilizing activities. As a result, the price of the Offered Shares may be higher than the price that might otherwise exist in the open market. Such transactions, if commenced, may be discontinued at any time. The Underwriters may carry out these transactions on the TSX and NYSE, in the over-the-counter market or otherwise.

The Underwriters propose to offer the Offered Shares to the public initially at the price specified on the cover page of this prospectus supplement. If all of the Offered Shares are not sold at the price specified in this prospectus supplement, the Underwriters may decrease the offering price and change the other selling terms. The compensation realized by the Underwriters will decrease by the amount that the aggregate offering price paid by the purchasers for the Offered Shares is less than the gross proceeds paid by the Underwriters to the Company. The decrease in the offering price will not decrease the amount of net proceeds of the Offering to the Company.

The Company has agreed, pursuant to the Underwriting Agreement, to indemnify the Underwriters and their affiliates and their directors, officers, employees, shareholders and agents and each other person, if any, controlling the Underwriters or their affiliates and against certain liabilities, including liabilities under Canadian and United States securities legislation in certain circumstances or to contribute to payments the Underwriters may have to make because of such liabilities.

Except as contemplated by the Underwriting Agreement, the Company has agreed that it will not, without the prior written consent of the Lead Underwriter (not to be unreasonably withheld), directly or indirectly issue, negotiate, announce or agree to sell or issue any Common Shares or securities or other financial instruments convertible into or having the right to acquire Common Shares of the Company, other than issuances (i) as contemplated in the Underwriting Agreement; (ii) pursuant to the grant of convertible awards in the normal course pursuant to the Company's employee equity incentive plan or issuance of securities pursuant to the exercise or conversion, as the case may be, of options or securities of the Company outstanding on the date hereof; or (iii) an issuance of options or securities in connection with a bona fide acquisition by the Company (subject to certain limitations contained in the Underwriting Agreement).

The Company has agreed to use its commercially reasonable efforts to cause each of its directors and senior officers to enter into lock-up agreements in form and substance satisfactory to the Lead Underwriter, evidencing their agreement to not, without the consent of the Lead Underwriter (which consent shall not be unreasonably withheld or delayed) offer, sell, or resell (or announce any intention to do so) any securities of the Company held by such director or senior officer, or agree to or announce any such offer or sale for a period of 90 days following the Closing Date, other than (i) in connection with a third party take-over bid made to all holders of Common Shares or a similar acquisition of all of the Common Shares; (ii) with respect to an aggregate of 541,265 Common Shares, which includes 450,000 Common Shares issuable upon exercise of an aggregate of 450,000 outstanding stock options of the Company which expire on March 30, 2021; and (iii) securities sold to satisfy tax obligations on the exercise of convertible securities of the Company held by such director or senior officer.

The Underwriters and their affiliates have provided in the past to the Company and its affiliates, and may provide from time to time in the future, certain commercial banking, financial advisory, investment banking and other services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time, the Underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in the Company's debt or equity securities or loans, and may do so in the future.

Subscriptions for the Offered Shares will be received by the Underwriters subject to rejection or allotment in whole or in part and the right is reserved to close the subscription book at any time without notice. An electronic deposit evidencing the Offered Shares is expected to be registered to CDS and will be deposited with CDS on the Closing Date or such other date as may be agreed upon between the Company and the Underwriters. Except in limited circumstances, a purchaser of such Offered Shares will receive only a customer confirmation from the registered dealer through which such Offered Shares are purchased.

Deutsche Bank and Evercore are not registered as investment dealers in any Canadian jurisdiction for the purposes of the Offering and, accordingly, Deutsche Bank and Evercore will not offer and sell the Offered Shares in Canada.

The Common Shares are listed on the TSX and the NYSE.  The Company has applied to list the Offered Shares for trading on the TSX and the NYSE. The listing of the Offered Shares on the TSX and the NYSE will be subject to the Company fulfilling of all of the requirements of the TSX and NYSE, respectively. On January 19, 2021, the last trading day before the date of this prospectus supplement on the TSX and the NYSE, the closing prices of the Common Shares on such exchanges were C$34.06 and US$26.82, respectively.

DIVIDENDS

The Company has no fixed dividend policy and the Company has not declared any dividends on its Common Shares since its incorporation. The Company anticipates that all available funds will be used to undertake exploration and development programs on its mineral properties as well as for the acquisition of additional mineral properties. The payment of dividends in the future will depend, among other things, upon the Company's earnings, capital requirements and operating and financial condition. Generally, dividends can only be paid if a corporation has retained earnings. There can be no assurance that the Company will generate sufficient earnings to allow it to pay dividends.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

In the opinion of Cassels Brock & Blackwell LLP, Canadian counsel to the Company, and Blake, Cassels & Graydon ‎LLP, Canadian counsel to the ‎Underwriters, ‎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 person who acquires Offered Shares as beneficial owner pursuant to the Offering and who, for the purposes of the Tax Act, and at all relevant times: (i) deals at arm's length with the Company and the Underwriters; (ii) is not affiliated with the Company or the Underwriters; and (iii) acquires and holds the Offered Shares as capital property (a "Holder").

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 or concern in the nature of trade.

This summary is not applicable to a Holder: (i) that is a "financial institution" within the meaning of section 142.2 of the Tax Act; (ii) that is a "specified financial institution" as defined in the Tax Act; (iii) that has made a "functional currency" reporting election under section 261 of the Tax Act; (iv) an interest in which is a "tax shelter investment" for the purposes of the Tax Act; (v) that has entered into or will enter into a "derivative forward agreement" or "synthetic disposition arrangement", each as defined in the Tax Act, in respect of Offered Shares; or (vi) that receives dividends on the Offered Shares under or as part of a "dividend rental arrangement", as defined in the Tax Act. Such Holders should consult their own tax advisors with respect to an investment in Offered Shares.

Additional considerations, not discussed herein, may be applicable to a Holder that is a corporation resident in Canada, and 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. Such Holders should consult their own tax advisors. 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.

S-18

This summary is based upon: (i) the current provisions of the Tax Act and the Regulations in force as of the date hereof; (ii) except as described below, all specific proposals ("Proposed Amendments") to amend the Tax Act or the Regulations that have been publicly announced by, or on behalf of, the Minister of Finance (Canada) prior to the date hereof; and (iii) counsel's understanding of the current published administrative policies and assessing practices of the Canada Revenue Agency ("CRA"). No assurance can be given that the Proposed Amendments will be enacted or otherwise implemented in their current form, if at all. If the Proposed Amendments are not enacted or otherwise implemented as presently proposed, the tax consequences may not be as described below in all cases. Other than the Proposed Amendments, this summary does not take into account or anticipate any changes in law, the CRA's administrative policies or assessing practices, whether by legislative, regulatory, administrative, governmental or judicial decision or action, nor does it take into account any provincial, territorial or foreign income tax legislation or considerations, which considerations may differ significantly from the Canadian federal income tax considerations discussed in this summary.

This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Holder. Accordingly, Holders should consult their own tax advisors with respect to their 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 converted into Canadian dollars based on the exchange rates as determined in accordance with the Tax Act.

Holders Resident in Canada

This section of the summary is generally applicable to a Holder who, at all relevant times, is, or is deemed to be, resident in Canada for the purposes of the Tax Act (a "Resident Holder"). A Resident Holder 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 deem the Offered Shares, and every other "Canadian security" (as defined in the Tax Act), held by such Resident Holder in the taxation year of the election and in all subsequent taxation years to be capital property. Resident Holders should consult with their own tax advisors regarding this election.

Taxation of Dividends

A Resident Holder will be required to include in computing its income for a taxation year any taxable dividends received or deemed to be received on the Offered Shares.

In the case of a Resident Holder who is an individual (including certain trusts), such dividends (including deemed dividends) received on the Offered Shares will be subject to the gross-up and dividend tax credit rules in the Tax Act normally applicable to "taxable dividends" received from a "taxable Canadian corporation" (each as defined in the Tax Act).  An enhanced gross-up and dividend tax credit will be available to individuals in respect of "eligible dividends" designated by the Company to the Resident Holder in accordance with the provisions of the Tax Act. 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, the amount of any such taxable dividend (including a deemed dividend) that is included in its income for a taxation year will generally be deductible in computing its taxable income for that taxation year. In certain circumstances, subsection 55(2) of the Tax Act will treat a taxable dividend received (or deemed to be 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 in this regard.

A Resident Holder that is a "private corporation" or a "subject corporation" (as defined in the Tax Act) may be liable to pay a refundable tax under Part IV of the Tax Act on dividends received on the Offered Shares to the extent such dividends are deductible in computing the Resident Holder's taxable income for the year. A "subject corporation" is generally a corporation (other than a private corporation) resident in Canada and controlled directly or indirectly by or for the benefit of an individual (other than a trust) or a related group of individuals (other than trusts).

Dispositions of Offered Shares

A Resident Holder who disposes of or is deemed to have disposed of a Offered Share (other than a disposition to the Company that is not a sale in the open market in the manner in which shares would normally be purchased by any member of the public in an open market) will generally realize a capital gain (or capital loss) in the taxation year of the disposition equal to the amount by which the proceeds of disposition of the Offered Share net of any reasonable costs of disposition, are greater (or are less) than the adjusted cost base to the Resident Holder of the Offered Share immediately before the disposition or deemed disposition. The adjusted cost base to a Resident Holder of a Offered Share will be determined by averaging the cost of that Offered Share with the adjusted cost base (determined immediately before the acquisition of the Offered Share) of all other Common Shares held as capital property at that time by the Resident Holder. Such capital gain (or capital loss) will be subject to the tax treatment described below under "Holders Resident in Canada - Taxation of Capital Gains and Capital Losses".

S-19

Taxation of Capital Gains and Capital Losses

A Resident Holder will generally be required to include in computing its income for the taxation year of disposition, one-half of the amount of any capital gain (a "taxable capital gain") realized in such year. Subject to and in accordance with the provisions of the Tax Act, a Resident Holder will generally be required to deduct one-half of the amount of any capital loss (an "allowable capital loss") against taxable capital gains realized in the taxation year of disposition. Allowable capital losses in excess of taxable capital gains for the taxation year of disposition may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any subsequent taxation year against net taxable capital gains realized in such years, to the extent and under the circumstances specified in the Tax Act.

The amount of any capital loss realized on the disposition or deemed disposition of a Offered Share by a Resident Holder that is a corporation may, in certain circumstances, be reduced by the amount of dividends received or deemed to have been received by it on such Offered Shares to the extent and under the circumstances specified in the Tax Act. Similar rules may apply where a Resident Holder that is a corporation is a member of a partnership or a beneficiary of a trust that owns Offered Shares, directly or indirectly, through a partnership or trust. Resident Holders to whom these rules may be relevant should consult their own tax advisors.

Other Income Taxes

A Resident Holder that is, throughout the relevant taxation year, a "Canadian-controlled private corporation" (as defined in the Tax Act) may be liable to pay an additional refundable tax on its "aggregate investment income" (as defined in the Tax Act) for the year, including any dividends or deemed dividends that are not deductible in computing the Resident Holder's taxable income and taxable capital gains.

Generally, a Resident Holder that is an individual (other than certain trusts) that receives or is deemed to have received taxable dividends on the Offered Shares or realizes a capital gain on the disposition or deemed disposition of Offered Shares may be liable for minimum tax under the Tax Act. Resident Holders that are individuals should consult their own tax advisors in this regard.

Holders Not Resident in Canada

This portion of the summary is generally applicable to a Holder who, at all relevant times, for purposes of the Tax Act: (i) is not, and is not deemed to be, resident in Canada; and (ii) does not use or hold and is not and will not be deemed to use or hold the Offered Shares in connection with carrying on a business in Canada (a "Non-Resident Holder"). This summary does not apply to a Non-Resident Holder that carries on, or is deemed to carry on, an insurance business in Canada and elsewhere or that is an "authorized foreign bank" (as defined in the Tax Act). Such Non-Resident Holders should consult their own tax advisors.

Taxation of Dividends

Dividends paid or credited or deemed under the Tax Act to be paid or credited by the Company to a Non-Resident Holder on the Offered Shares will generally be subject to Canadian withholding tax at the rate of 25% on the gross amount of the dividend, unless such rate is reduced by the terms of an applicable income tax treaty or convention. Under the Canada-United States Tax Convention (1980), as amended (the "US Treaty"), the rate of withholding tax on dividends paid or credited to a Non-Resident Holder who is resident in the U.S. for purposes of the US Treaty, is the beneficial owner of the dividends, and is fully entitled to benefits under the US Treaty (a "U.S. Holder") is generally limited to 15% of the gross amount of the dividend. The rate of withholding tax is further reduced to 5% if the beneficial owner of such dividend is a U.S. Holder that is a corporation that owns, directly or indirectly, at least 10% of the voting stock of the Company.

S-20

Dispositions of Offered Shares

A Non-Resident Holder will not be subject to tax under the Tax Act in respect of any capital gain realized on a disposition or deemed disposition of an Offered Share, nor will capital losses arising therefrom be recognized under the Tax Act,  unless the Offered Share is, or is deemed to be, "taxable Canadian property" of the Non-Resident Holder for the purposes of the Tax Act and the Non-Resident Holder is not entitled to relief under an applicable income tax treaty or convention between Canada and the country in which the Non-Resident Holder is resident.

Provided that the Offered Shares are listed on a "designated stock exchange" for the purposes of the Tax Act (which currently includes the TSX and the NYSE), at the time of disposition, the Offered Shares generally will not constitute taxable Canadian property of a Non-Resident Holder at that time, unless at any time during the 60 month period immediately preceding the disposition the following two conditions are met concurrently, (i) 25% or more of the issued shares of any class or series of the capital stock of the Company were owned by, or belonged to, any combination of (a) the Non-Resident Holder, (b) persons with whom the Non-Resident Holder did not deal at arm's length, and (c) partnerships in which the Non-Resident Holder or a person described in (b) holds a membership interest directly or indirectly through one or more partnerships; and (ii) at such time, more than 50% of the fair market value of such shares was derived, directly or indirectly, from any combination of real or immovable property situated in Canada, "Canadian resource property" (as defined in the Tax Act), "timber resource property" (as defined in the Tax Act), or options in respect of, interests in, or for civil law rights in such properties, whether or not such property exists. Notwithstanding the foregoing, a Offered Share may also be deemed to be taxable Canadian property to a Non-Resident Holder for purposes of the Tax Act in certain other circumstances. Non-Resident Holders should consult their own tax advisors as to whether their Offered Shares constitute "taxable Canadian property" in their own particular circumstances.

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 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.

A Non-Resident Holder's capital gain (or capital loss) in respect of Offered Shares that constitute or are deemed to constitute taxable Canadian property (and are not "treaty-protected property" as defined in the Tax Act) will generally be computed in the manner described above under the headings "Holders Resident in Canada - Dispositions of Offered Shares" and "Holders Resident in Canada - Taxation of Capital Gains and Capital Losses". Such Non-Resident Holders should consult their own tax advisors.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a general summary of certain anticipated U.S. federal income tax considerations applicable to a US Holder (as defined below) arising from and relating to the acquisition, ownership and disposition of Offered Shares acquired pursuant to this prospectus supplement.

This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a US Holder as a result of the acquisition, ownership and disposition of Offered Shares acquired pursuant to this prospectus supplement. This summary does not take into account the individual facts and circumstances of any particular US Holder that may affect the US federal income tax considerations applicable to such US Holder of Offered Shares. Accordingly, this summary is not intended to be, and should not be construed as, legal or US federal income tax advice with respect to any US Holder. US Holders should consult their own tax advisors regarding the US federal, US state and local, and non-US tax consequences relating to the acquisition, ownership and disposition of Offered Shares.

No ruling from the U.S. Internal Revenue Service (the "IRS") or legal opinion has been requested, or will be obtained, regarding the potential U.S. federal income tax considerations applicable to US Holders as discussed in this summary. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the positions taken in this summary.

Scope of this Summary

Authorities

This summary is based on the Internal Revenue Code of 1986, as amended (the "Code"), regulations promulgated by the Department of the Treasury (whether final, temporary or proposed) ("Treasury Regulations"), U.S. court decisions published rulings and administrative positions of the IRS, and the Canada-U.S. Tax Convention, in each case, in effect as of the date of this prospectus supplement. Any of the authorities on which this summary is based could be changed in a material and adverse manner possibly with retroactive effect, at any time.

S-21

US Holder

For purposes of this section, a "US Holder" is a beneficial owner of Offered Shares acquired pursuant to this prospectus supplement that is (a) an individual who is a citizen or resident of the United States for US federal income tax purposes; (b) a corporation, or other entity treated as a corporation for US federal income tax purposes, that is created or organized in or under the laws of the United States or any state in the United States or the District of Columbia; (c) an estate if the income of such estate is subject to US federal income tax regardless of the source of such income; or (d) a trust if (i) such trust has validly elected to be treated as a US person for US federal income tax purposes, or (ii) a US court is able to exercise primary supervision over the administration of such trust and one or more US persons have the authority to control all substantial decisions of such trust.

Non-US Holder

For purposes of this summary, a "Non-US Holder" is a beneficial owner of Offered Shares that is neither a US Holder nor a partnership (or other "pass-through" entity for US federal income tax purposes.) This summary does not address the US federal income tax considerations applicable to Non-US Holders relating to the acquisition, ownership and disposition of Offered Shares. Accordingly, Non-US Holders should consult their own tax advisors regarding the US federal, US state and local, and non-US tax consequences (including the potential application of and operation of the Canada-U.S. Tax Convention or any other tax treaties) relating to the acquisition, ownership, and disposition of Offered Shares.

US Holders Subject to Special US Federal Income Tax Rules Not Addressed

This summary does not address the U.S. federal income tax considerations applicable to US Holders that are subject to special provisions under the Code, including: (a) US Holders that are tax-exempt organizations, qualified retirement plans, individual retirement accounts or other tax deferred accounts; (b) US Holders that are financial institutions, underwriters, insurance companies, real estate investment trusts or regulated investment companies or that are broker-dealers, dealers, or traders in securities or currencies that elect to apply a mark-to-market accounting method; (c) US Holders that have a "functional currency" other than the US dollar; (d) US Holders that own Offered Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale or other integrated transaction; (e) US Holders that acquired Offered Shares in connection with the exercise of employee stock options or otherwise as compensation for services; (f) US Holders that hold Offered Shares other than as a capital asset (generally property held for investment purposes) within the meaning of Section 1221 of the Code; (g) US Holders that are partnerships or other flow-through entities; (h) US Holders that are subject to special tax accounting rules with respect to the Offered Shares; (i) US Holders that are subject to taxing jurisdictions other than, or in addition to, the United States; or (j) US Holders that own, directly, indirectly or by attribution, 10% or more, by voting power or value, of the outstanding shares of the Company. The summary below also does not address the impact of the Offering on persons who are US expatriates or former long-term residents of the United States subject to Section 877 or 877A of the Code. US Holders and others that are subject to special provisions under the Code, including US Holders described immediately above, should consult their own tax advisors regarding the U.S. federal income tax consequences relating to the acquisition, ownership and disposition of Offered Shares.

If a partnership (or entity or arrangement treated as a partnership for US federal tax purposes) holds Offered Shares, the tax treatment of a partner in the partnership (or other entity or arrangement treated as a partnership for US federal tax purposes) will generally depend on the status of the partner and the activities of the partnership. Partners in partnerships (or other entities or arrangements treated as partnerships for US federal tax purposes) that are beneficial owners of Offered Shares should consult their own tax advisors regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership and disposition of Offered Shares.

Tax Consequences Other than US Federal Income Tax Consequences Not Addressed

This summary does not address the US state and local tax, US estate, gift, and generation-skipping tax, US federal net investment income tax, US federal alternative minimum tax, or non-US tax consequences to US Holders relating to the acquisition, ownership, and disposition of Offered Shares. In addition, except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. Each US Holder should consult its own tax advisor regarding the US state and local tax, US estate, gift, and generation-skipping tax, US federal net investment income, US federal alternative minimum tax and non-US tax consequences relating to the acquisition, ownership, and disposition of Offered Shares.

US Federal Income Tax Consequences of the Acquisition, Ownership and Disposition of Offered Shares

Classification as a Passive Foreign Investment Company

S-22

As discussed below under "Passive Foreign Investment Company Rules - PFIC Status of the Company", the Company believes that it was a "passive foreign investment company" under Section 1297 of the Code ("PFIC") in 2019, it may have been a PFIC in 2020, and based on current business plans and financial expectations, the Company expects that it may be a PFIC for its current tax year and may be a PFIC in future tax years. No opinion of legal counsel or ruling from the IRS concerning the status of the Company as a PFIC has been obtained or is currently planned to be requested.  If the Company is classified as a PFIC in any taxable year in which a US Holder holds Offered Shares, the Company generally will be considered a PFIC with respect to such Offered Shares in subsequent taxable years even if the Company is otherwise not a PFIC in such subsequent taxable years. If the Company is considered to be a PFIC with respect to a US Holder's Offered Shares, such holder generally will be liable to pay income tax at the highest ordinary income tax rate on any "excess distribution" from the Company and on the US Holder's gain from the disposition of Offered Shares as if such excess distribution or gain had been recognized ratably over the US Holder's holding period for the Offered Shares, plus interest on such amount as if it were treated as a series of underpayments of tax in such prior years. Each US Holder should consult its own tax advisor regarding the classification of the Company as a PFIC and the consequences of such classification.

Distributions on Offered Shares

Subject to the PFIC rules discussed below, a US Holder that receives a distribution with respect to an Offered Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any Canadian income tax withheld from such distribution) to the extent of the current or accumulated "earnings and profits" of the Company, as computed for U.S. federal income tax purposes. To the extent that a distribution exceeds the current and accumulated "earnings and profits" of the Company, such distribution will be treated first as a tax-free return of capital to the extent of a US Holder's tax basis in the Offered Shares, and thereafter as a gain from the sale or exchange of such Offered Shares (see "Sale or Other Taxable Disposition of Offered Shares" below). However, the Company might not determine its current and accumulated earnings and profits in accordance with U.S. federal income tax principles, and US Holders might therefore assume that any distribution by the Company with respect to Offered Shares will constitute dividend income. Dividends received on Offered Shares will not be eligible for the "dividends received deduction" allowed to corporations under the Code with respect to dividends received from domestic corporations.

Subject to applicable limitations and provided the Company is eligible for the benefits of the Canada-U.S. Tax Convention or the Offered Shares are readily tradable on a United States securities market, dividends paid by the Company to non-corporate US Holders, including individuals, generally will be eligible for the preferential tax rates applicable to long-term capital gains for dividends, provided certain holding period and other conditions are satisfied, including that the Company is not classified as a PFIC in the tax year of distribution or in the preceding tax year. If the Company is not a PFIC, dividends paid to a US Holder that do not result in qualified dividend income generally will be taxed at ordinary income tax rates. The dividend rules are complex, and each US Holder should consult its own tax advisor regarding the application of such rules.

Sale or Other Taxable Disposition of Offered Shares

Subject to the PFIC rules discussed below, upon the sale or other taxable disposition of Offered Shares, a US Holder generally will recognize gain or loss in an amount equal to the difference between (a) the amount of cash plus the fair market value of any property received and (b) its tax basis in such Offered Shares sold or otherwise disposed of. Such gain or loss will be a long-term capital gain or loss if the Offered Shares has been held for more than one year and will be short-term gain or loss if the holding period is equal to or less than one year. Such gain generally will be treated as "US source" for purposes of applying the US foreign tax credit rules unless the gain is subject to tax in Canada and is re-sourced as "foreign source" under the Canada-U.S. Tax Convention and such US Holder elects to treat such gain or loss as "foreign source" (see a more detailed discussion at "Foreign Tax Credit" below). Long-term capital gains of certain non-corporate taxpayers are eligible for reduced rates of taxation. Deductions for capital losses are subject to complex limitations.

Foreign Tax Credit

A US Holder who pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on Offered Shares generally may elect to deduct or credit such tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a US Holder during a year.

Complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of a US Holder's US federal income tax liability that such US Holder's "foreign source" taxable income bears to such US Holder's worldwide taxable income. In applying this limitation, a US Holder's various items of income and deduction must be classified, under complex rules, as either "foreign source" or "US source." In addition, this limitation is calculated separately with respect to specific categories of income. Dividends paid by the Company generally will constitute "foreign source" income and generally will be categorized as "passive category income". Because the foreign tax credit rules are complex, US Holders should consult their own tax advisors regarding the foreign tax credit rules, including the source of any dividends paid to US Holders.

S-23

Subject to certain specific rules, foreign income and withholding taxes paid with respect to any distribution in respect of stock in a PFIC should qualify for the foreign tax credit. The rules relating to distributions by a PFIC are complex, and a US Holder should consult with its own tax advisor with respect to any distribution received from a PFIC.

Receipt of Foreign Currency

The amount of any distribution paid in foreign currency to a US Holder in connection with the ownership of Offered Shares, or on the sale, exchange or other taxable disposition of Offered Shares, generally will be equal to the US dollar value of such foreign currency based on the exchange rate applicable on the date of actual or constructive receipt (regardless of whether such foreign currency is converted into US dollars at that time). If the foreign currency received is not converted into US dollars on the date of receipt, a US Holder will have a basis in the foreign currency equal to its US dollar value on the date of receipt. A US Holder that receives foreign currency and converts such foreign currency into US dollars at a conversion rate other than the rate in effect on the date of receipt may have a foreign currency exchange gain or loss, which generally would be treated as US source ordinary income or loss for foreign tax credit purposes. Different rules may apply to US Holders subject to the accrual method of tax accounting. US Holders should consult their own US tax advisors regarding the US federal income tax consequences of receiving, owning and disposing of foreign currency.

Passive Foreign Investment Company Rules

If the Company is a PFIC within the meaning of Section 1297 of the Code at any time during a US Holder's holding period, then certain different and potentially adverse tax consequences would apply to such US Holder's acquisition, ownership and disposition of Offered Shares.

PFIC Status of the Company

The Company generally will be a PFIC if, for a given tax year, (a) 75% or more of the gross income of the Company for such tax year is passive income (the "income test") or (b) 50% or more of the assets held by the Company either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets (the "asset test"). "Gross income" generally includes all income less the cost of goods sold, and "passive income" includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions. Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all of a foreign corporation's commodities are stock in trade or inventory, depreciable property used in a trade or business, or supplies regularly used or consumed in a trade or business.

For purposes of the PFIC income test and asset test described above, if the Company owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, the Company will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and asset test described above, "passive income" does not include any interest, dividends, rents or royalties that are received or accrued by the Company from a "related person" (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income.

Under certain attribution rules, if the Company is a PFIC, US Holders will be deemed to own their proportionate share of any subsidiary of the Company which is also a PFIC (a "lower-tier PFIC"), and will be subject to US federal income tax on (a) a distribution on the shares of a lower-tier PFIC and (b) a disposition of shares of a lower-tier PFIC, both as if the US Holder directly held the shares of such lower-tier PFIC.

The Company believes that it was a PFIC in 2019 and that it may have been a PFIC for 2020, and the Company expects, based on current business plans and financial expectations, that it may be a PFIC for its current tax year and future tax years. No opinion of legal counsel or ruling from the IRS concerning the status of the Company as a PFIC has been obtained or is currently planned to be requested. The determination of whether the Company (or a subsidiary of the Company) was, or will be, a PFIC for a tax year depends, in part, on the application of complex US federal income tax rules, which are subject to differing interpretations. In addition, whether the Company (or subsidiary) will be a PFIC for any tax year depends on the assets and income of the Company (and each such subsidiary) over the course of each such tax year and, as a result, cannot be predicted with certainty as of the date of this prospectus supplement. Accordingly, there can be no assurance that the IRS will not challenge any determination made by the Company (or subsidiary) concerning its PFIC status or that the Company (and any subsidiary) was not, or will not be, a PFIC for any tax year. US Holders should consult their own tax advisors regarding the PFIC status of the Company and any subsidiary of the Company.

S-24

Default PFIC Rules under Section 1291 of the Code

If the Company is a PFIC, the US federal income tax consequences to a US Holder of the acquisition, ownership and disposition of Offered Shares will depend on whether such US Holder makes a Qualified Electing Fund Election under Section 1295 of the Code ("QEF Election") or makes a mark-to-market election under Section 1296 of the Code (a "Mark-to-Market Election") with respect to Offered Shares. A US Holder that does not make either a QEF Election or a Mark-to-Market Election will be referred to in this summary as a "Non-Electing US Holder."

A Non-Electing US Holder will be subject to the rules of Section 1291 of the Code with respect to (a) any gain recognized on the sale or other taxable disposition of Offered Shares and (b) any excess distribution paid on the Offered Shares. A distribution generally will be an "excess distribution" to the extent that such distribution (together with all other distributions received in the current tax year) exceeds 125% of the average distributions received during the three preceding tax years (or during a US Holder's holding period for the Offered Shares, if shorter).

If the Company is a PFIC, under Section 1291 of the Code any gain recognized on the sale or other taxable disposition of Offered Shares (including an indirect disposition of shares of a lower-tier PFIC), and any excess distribution paid on Offered Shares (or a distribution by a lower-tier PFIC to its shareholder that is deemed to be received by a US Holder) must be ratably allocated to each day of a Non-Electing US Holder's holding period for the Offered Shares, as applicable. The amount of any such gain or excess distribution allocated to the tax year of disposition or excess distribution and to years before the Company became a PFIC, if any, would be taxed as ordinary income. The amounts allocated to any other tax year would be subject to US federal income tax at the highest tax rate applicable to ordinary income in each such year without regard to the US Holder's other tax attributes, and an interest charge would be imposed on the tax liability for each such year, calculated as if such tax liability had been due in each such year. A Non-Electing US Holder that is not a corporation must treat any such interest paid as "personal interest," which is not deductible.

If the Company is a PFIC for any tax year during which a Non-Electing US Holder holds Offered Shares, the Company will continue to be treated as a PFIC with respect to such Non-Electing US Holder, regardless of whether the Company ceases to be a PFIC in one or more subsequent years. If the Company ceases to be a PFIC, a Non-Electing US Holder may terminate this deemed PFIC status with respect to Offered Shares by electing to recognize gain (which will be taxed under the rules of Section 1291 of the Code discussed above) as if such Offered Shares were sold on the last day of the last tax year for which the Company was a PFIC.

QEF Election

If the Company is a PFIC and a US Holder makes a QEF Election for the first tax year in which its holding period of its Offered Shares begins, such US Holder generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to its Offered Shares. However, a US Holder that makes a QEF Election will be subject to US federal income tax on such US Holder's pro rata share of (a) the net capital gain of the Company, which will be taxed as long-term capital gain to such US Holder, and (b) the ordinary earnings of the Company, which will be taxed as ordinary income to such US Holder. Generally, "net capital gain" is the excess of (a) net long-term capital gain over (b) net short-term capital gain, and "ordinary earnings" are the excess of (a) "earnings and profits" over (b) net capital gain. A US Holder that makes a QEF Election will be subject to US federal income tax on such amounts for each tax year in which the Company is a PFIC, regardless of whether such amounts are actually distributed to such US Holder by the Company. However, a US Holder that makes a QEF Election may, subject to certain limitations, elect to defer payment of current US federal income tax on such amounts, subject to an interest charge. If such US Holder is not a corporation, any such interest paid will be treated as "personal interest," which is not deductible.

A US Holder that makes a QEF Election generally (a) may receive a tax-free distribution from the Company to the extent that such distribution represents "earnings and profits" of the Company that were previously included in income by the US Holder because of such QEF Election and (b) will adjust such US Holder's tax basis in the Offered Shares to reflect the amount included in income or allowed as a tax-free distribution because of such QEF Election. In addition, a US Holder that makes a QEF Election generally will recognize capital gain or loss on the sale or other taxable disposition of Offered Shares.

The procedure for making a QEF Election, and the US federal income tax consequences of making a QEF Election, will depend on whether such QEF Election is timely. A QEF Election will be treated as timely if it is made for the first year in the US Holder's holding period for the Offered Shares in which the Company was a PFIC. A US Holder may make a timely QEF Election by filing the appropriate QEF Election documents at the time such US Holder files a US federal income tax return for such year.

S-25

A QEF Election will apply to the tax year for which such QEF Election is made and to all subsequent tax years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election. If a US Holder makes a QEF Election and, in a subsequent tax year, the Company ceases to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those tax years in which the Company is not a PFIC. Accordingly, if the Company becomes a PFIC in a subsequent tax year, the QEF Election will be effective, and the US Holder will be subject to the QEF rules described above during a subsequent tax year in which the Company qualifies as a PFIC.

For each tax year that the Company qualifies as a PFIC as determined by the Company based on its reasonable analysis, upon the written request of a US Holder, the Company will make publicly available on its website a "PFIC Annual Information Statement" as described in Treasury Regulation Section 1.1295 1(g) (or any successor Treasury Regulation) and all information and documentation that a US Holder is required to obtain for U.S. federal income tax purposes in making a QEF Election with respect to the Company. Each US Holder should consult its own tax advisors regarding the availability of, and procedure for making, a QEF Election.

Mark-to-Market Election

A US Holder may make a Mark-to-Market Election only if the Offered Shares are marketable stock. The Offered Shares generally will be "marketable stock" if they are regularly traded on (a) a national securities exchange that is registered with the SEC; (b) the national market system established pursuant to section 11A of the Securities and Exchange Act of 1934; or (c) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (i) such foreign exchange has trading volume, listing, financial disclosure and other requirements and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced; and (ii) the rules of such foreign exchange ensure active trading of listed stocks. If such stock is traded on such a qualified exchange or other market, such stock generally will be "regularly traded" for any calendar year during which such stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter.

A US Holder that makes a Mark-to-Market Election with respect to its Offered Shares generally will not be subject to the rules of Section 1291 of the Code discussed above. However, if a US Holder does not make a Mark-to-Market Election beginning in the first tax year of such US Holder's holding period for Offered Shares or such US Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of, and distributions on, the Offered Shares.

A US Holder that makes a Mark-to-Market Election will include in ordinary income, for each tax year in which the Company is a PFIC, an amount equal to the excess, if any, of (a) the fair market value of the Offered Shares, as of the close of such tax year over (b) such US Holder's tax basis in such Offered Shares. A US Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the excess, if any, of (i) such US Holder's adjusted tax basis in the Offered Shares over (ii) the fair market value of such Offered Shares (but only to the extent of the net amount of previously included income as a result of the Mark-to-Market Election for prior tax years).

US Holders that make a Mark-to-Market Election generally also will adjust their tax basis in the Offered Shares to reflect the amount included in gross income or allowed as a deduction because of such Mark-to-Market Election. In addition, upon a sale or other taxable disposition of Offered Shares, a US Holder that makes a Mark-to-Market Election will recognize ordinary income or loss (not to exceed the excess, if any, of (a) the amount included in ordinary income because of such Mark-to-Market Election for prior tax years over (b) the amount allowed as a deduction because of such Mark-to-Market Election for prior tax years).

A Mark-to-Market Election applies to the tax year in which such Mark-to-Market Election is made and to each subsequent tax year, unless the Offered Shares cease to be "marketable stock" or the IRS consents to revocation of such election. US Holders should consult their own tax advisors regarding the availability of, and procedure for making, a Mark-to-Market Election.

Although a US Holder may be eligible to make a Mark-to-Market Election with respect to Offered Shares, no such election may be made with respect to the stock of any lower-tier PFIC that a US Holder is treated as owning because such stock is not marketable. Hence, the Mark-to-Market Election will not be effective to eliminate the interest charge described above with respect to deemed dispositions of lower-tier PFIC stock or distributions from a lower-tier PFIC.

Other PFIC Rules

Under Section 1291(f) of the Code, the IRS has issued proposed Treasury Regulations that, subject to certain exceptions, would cause a US Holder that had not made a timely QEF Election to recognize gain (but not loss) upon certain transfers of Offered Shares that would otherwise be tax-deferred (e.g., gifts and exchanges pursuant to corporate reorganizations) in the event the Company is a PFIC during such US Holder's holding period for the relevant shares. However, the specific US federal income tax consequences to a US Holder may vary based on the manner in which Offered Shares are transferred.

Certain additional adverse rules will apply with respect to a US Holder if the Company is a PFIC, regardless of whether such US Holder makes a QEF Election. For example, under Section 1298(b)(6) of the Code, a US Holder that uses Offered Shares as security for a loan will, except as may be provided in Treasury Regulations, be treated as having made a taxable disposition of such Offered Shares.

If the Company were a PFIC, a US Holder would be required to attach a completed IRS Form 8621 to its tax return every year in which it recognized gain on a disposition of the Offered Shares or received an excess distribution. In addition, subject to certain rules intended to avoid duplicative filings, US Holders may also be required to file an annual information return on IRS Form 8621 with respect to each PFIC in which the US Holder holds a direct or indirect interest. US Holders should consult their own tax advisors regarding their filing obligations with respect to such information returns.

In addition, a US Holder who acquires Offered Shares from a decedent will not receive a "step up" in tax basis of such Offered Shares to fair market value unless such decedent had a timely and effective QEF Election in place.

Special rules also apply to foreign tax credits that a US Holder may claim on a distribution from a PFIC.

The PFIC rules are complex, and US Holders should consult their own tax advisors regarding the PFIC rules and how they may affect the US federal income tax consequences of the acquisition, ownership, and disposition of Offered Shares in the event the Company is a PFIC at any time during the holding period for such Offered Shares.

Information Reporting and Backup Withholding

Certain US Holders are required to report information relating to an interest in Offered Shares, subject to certain exceptions (including an exception for Offered Shares held in accounts maintained by certain financial institutions), by attaching a completed IRS Form 8938, Statement of Specified Foreign Financial Assets, with their tax return for each year in which they hold an interest in Offered Shares. Failure to do so could result in substantial penalties and in the extension of the statute of limitations with respect to such holder's US federal income tax returns. US Holders are urged to consult their own tax advisors regarding information reporting requirements relating to their ownership of the Offered Shares.

Payments made within the United States, or by a US payor or US middleman, of dividends on Offered Shares, and proceeds arising from certain sales or other taxable dispositions of Offered Shares, may be subject to information reporting and backup withholding tax, currently at the rate of 24%, if a US Holder (a) fails to furnish such US Holder's correct US social security or other taxpayer identification number (generally on Form W-9); (b) furnishes an incorrect US taxpayer identification number; (c) is notified by the IRS that such US Holder has previously failed to properly report items subject to backup withholding tax; or (d) fails under certain circumstances to certify, under penalty of perjury, that such US Holder has furnished its correct US taxpayer identification number and that the IRS has not notified such US Holder that it is subject to backup withholding tax. However, US Holders that are corporations generally are excluded from these information reporting and backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the US backup withholding rules will be allowed as a credit against a US Holder's US federal income tax liability, if any, or will be refunded, if such US Holder timely furnishes the required information to the IRS.

The discussion of reporting requirements set forth above is not intended to constitute a complete description of all reporting requirements that may apply to a US Holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax, and under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting requirement. US Holders should consult their own tax advisors regarding the information reporting and backup withholding tax rules.

THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX CONSIDERATIONS APPLICABLE TO US HOLDERS WITH RESPECT TO THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF OFFERED SHARES. US HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE TAX CONSIDERATIONS APPLICABLE TO THEM IN THEIR OWN PARTICULAR CIRCUMSTANCES.

LEGAL MATTERS

Certain legal matters relating to the Offering hereby will be passed upon on behalf of the Company by Cassels Brock & Blackwell LLP, with respect to Canadian legal matters, and by Dorsey & Whitney LLP, with respect to United States legal matters and on behalf of the Underwriters by Blake, Cassels & Graydon LLP with respect to certain Canadian legal matters, and Skadden, Arps, Slate, Meagher & Flom LLP with respect to certain United States legal matters.

As of the date hereof Cassels Brock & Blackwell LLP, and its partners and associates, and Blake, Cassels & Graydon LLP, and its partners and associates, beneficially own, directly or indirectly, in their respective groups, less than 1% of any class of outstanding securities of the Company.

ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

The Company is a corporation incorporated under and governed by the BCBCA. Some of the directors and officers of the Company, and some of the experts named in this prospectus supplement, are residents of Canada or otherwise reside outside the United States, and all or a substantial portion of their assets, and a certain portion of the Company's assets, are located outside the United States. The Company has appointed an agent for service of process in the United States, but it may be difficult for investors who reside in the United States to effect service of process upon these persons in the United States, or to enforce a U.S. court judgment predicated upon the civil liability provisions of the U.S. federal securities laws against the Company or any of these persons. There is substantial doubt whether an action could be brought in Canada in the first instance predicated solely upon U.S. federal securities laws. 

We have filed with the SEC, concurrently with the Registration Statement of which this prospectus supplement is a part, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Company appointed CT Corporation System as its 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 or related to or concerning the Offering.

AUDITOR, REGISTRAR AND TRANSFER AGENT

PricewaterhouseCoopers LLP, Chartered Professional Accountants, is the auditor of the Company and has confirmed that it is independent of the Company within the meaning of the Code of Professional Conduct of the Chartered Professional Accountants of British Columbia and in accordance with the applicable rules and regulations of the SEC and the Public Company Accounting Oversight Board (United States).

The registrar and transfer agent for the Common Shares is Computershare Investor Services Inc., located at its principal offices in Vancouver, British Columbia.

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. See "Plan of Distribution".

Information has been incorporated by reference in this short form base shelf prospectus from documents filed with securities commissions or similar regulatory authorities in Canada. Copies of the documents incorporated herein by reference may be obtained on request without charge from the Corporate Secretary of Lithium Americas Corp. at 300-900 West Hastings Street, Vancouver, British Columbia, Canada, V6C 1E5, e-mail: legal@lithiumamericas.com, and are also available electronically at www.sedar.com.

The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent, if any, engaged by the Company and/or the selling securityholders in connection with the offering and sale of the Securities and will set forth the terms of the offering of such Securities, the method of distribution of such Securities including, to the extent applicable, the proceeds to us and/or the selling securityholders, and, to the extent applicable, any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms of the plan of distribution. If offered on a non-fixed price basis, Securities may be offered at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at prices to be negotiated with purchasers at the time of sale, which prices may vary between purchasers and during the period of distribution.

ABOUT THIS PROSPECTUS

This Prospectus provides a general description of the Securities that we and/or a selling securityholder may offer. Each time we and/or a selling securityholder sell Securities under this Prospectus, we will prepare a Prospectus Supplement that will contain specific information about the terms of that offering. The Prospectus Supplement may also add, update or change information contained in this Prospectus. Before investing in any Securities, you should read both this Prospectus and any applicable Prospectus Supplement, together with the additional information described below and in the applicable Prospectus Supplement under "Documents Incorporated by Reference".

Investors should rely only on the information contained in or incorporated by reference in this Prospectus and any applicable Prospectus Supplement and are not entitled to rely on certain parts of the information contained in or incorporated by reference in this Prospectus and any applicable Prospectus Supplement to the exclusion of the remainder. Neither we nor any selling securityholder has authorized anyone to provide investors with different or additional information. Neither we nor any selling securityholder is making an offer of Securities in any jurisdiction where the offer or sale of Securities is not permitted by law. Prospective investors should not assume that the information contained in or incorporated by reference in this Prospectus and any applicable Prospectus Supplement is accurate as of any date other than the date on the front of such documents (including the documents incorporated by reference herein and therein), regardless of the time of delivery of this Prospectus, any applicable Prospectus Supplement or any sale of Securities.

Unless we have indicated otherwise, or the context otherwise requires, references in this Prospectus and any Prospectus Supplement to "LAC", the "Company", "we", "us" and "our" refer to Lithium Americas Corp. and/or, as applicable, one or more of its subsidiaries and/or, as applicable, its joint venture.

These statements relate to future events or the Company's future performance. All statements, other than statements of historical fact, may be forward-looking information. Information concerning mineral resource and mineral reserve estimates also may be deemed to be forward-looking information in that it reflects a prediction of mineralization that would be encountered if a mineral deposit were developed and mined. Forward-looking information generally can be identified by the use of words such as "seek", "anticipate", "plan", "continue", "estimate", "expect", "may", "will", "project", "predict", "propose", "potential", "targeting", "intend", "could", "might", "should", "believe" and similar expressions. These statements involve known and unknown risks, uncertainties and other factors that may cause actual results or events to differ materially from those anticipated in such forward-looking information.

In particular, this Prospectus contains or incorporates by reference forward-looking information, including, without limitation, with respect to the following matters or the Company's expectations relating to such matters: successful development of the Cauchari-Olaroz and Thacker Pass Projects, including timing, progress, construction, milestones, anticipated productions and results thereof; the expected benefits from the Project Investment; the expected benefits from the 2020 Cauchari Transaction; expectations and anticipated impact of any COVID-19 cases on site; statements regarding anticipated decision making with respect to Minera Exar; capital expenditures and programs; estimates of the mineral resources and mineral reserves at the Company's properties; development of mineral resources and mineral reserves; government regulation of mining operations and treatment under governmental and taxation regimes; the future price of commodities, including lithium; the realization of mineral resources and mineral reserves estimates, including whether mineral resources will ever be developed into mineral reserves and information and underlying assumptions related thereto; the timing and amount of future production; currency exchange and interest rates; expected outcome and timing of environmental surveys and permit applications and other environmental matters; the Company's ability to raise capital; expected expenditures to be made by the Company on its properties; the timing, cost, quantity, capacity and product quality of production of the Cauchari-Olaroz Project, which is held and operated through the Company's joint venture with Ganfeng; successful operation of the Cauchari-Olaroz Project under its co-ownership structure; whether the Company will ever be able to realize on the additional debt funding commitment from Bangchak, including the terms and timing thereof; ability to produce high quality battery grade lithium carbonate; the timing, cost, quantity, capacity and product quality of production at the Thacker Pass Project; results of the Company's engineering, design, permitting program at the Thacker Pass Project, including that the Company meets deadlines and receives permits as anticipated; successful results from the Company's testing facility and third-party tests related thereto; capital costs, operating costs, sustaining capital requirements, after tax net present value and internal rate of return, payback period, sensitivity analyses, net cash flows and EBITDA of the Cauchari-Olaroz Project and the Thacker Pass Project; timing, results and completion of the Thacker Pass Project feasibility study; the Company's share of the expected capital expenditures for the construction of the Cauchari-Olaroz Project and for permitting and Thacker Pass Project feasibility study activities at the Thacker Pass Project; ability to achieve capital cost efficiencies; stability and inflation related to the Argentine peso, whether the Argentine government implements additional foreign exchange and capital controls, and the effect of current or any additional regulations on the Company's operations; approval of pending patents; and the potential for partnership and financing scenarios for the Thacker Pass Project.

Forward-looking information does not take into account the effect of transactions or other items announced or occurring after the statements are made. Forward-looking information is based upon a number of expectations and assumptions and is subject to a number of risks and uncertainties, many of which are beyond the Company's control, that could cause actual results to differ materially from those that are disclosed in or implied by such forward-looking information. With respect to forward-looking information listed above and incorporated by reference herein, the Company has made assumptions regarding, among other things:

•current technological trends;

•a cordial business relationship between the Company and Ganfeng for the Cauchari-Olaroz Project;

•ability of the Company to fund, advance and develop the Cauchari-Olaroz Project and the Thacker Pass Project;

•the Company's ability to operate in a safe and effective manner;

•uncertainties relating to receiving and maintaining mining, exploration, environmental and other permits or approvals in Nevada and Argentina;

•demand for lithium, including that such demand is supported by growth in the electric vehicle market;

•the impact of increasing competition in the lithium business, and LAC's competitive position in the industry;

•general economic conditions;

•the stable and supportive legislative, regulatory and community environment in the jurisdictions where the Company operates;

•stability and inflation of the Argentinian peso, including any foreign exchange or capital controls which may be enacted in respect thereof, and the effect of current or any additional regulations on the Company's operations;

•the impact of unknown financial contingencies, including litigation costs, on the Company's operations;

•gains or losses, in each case, if any, from short-term investments in Argentine bonds and equities;

•estimates of and unpredictable changes to the market prices for lithium;

•exploration, development and construction costs for the Cauchari-Olaroz Project and the Thacker Pass Project;

•estimates of mineral resources and mineral reserves, including whether mineral resources will ever be developed into mineral reserves;

•reliability of technical data;

- 2 -

•anticipated timing and results of exploration, development and construction activities;

•timely responses from governmental agencies responsible for reviewing and considering the Company's permitting activities at the Thacker Pass Project;

•the Company's ability to obtain additional financing, including pursuant to the additional debt funding commitment from Bangchak, on satisfactory terms or at all;

•the ability to develop and achieve production at any of the Company's mineral exploration and development properties;

•the impact of COVID-19 on the Company's business;

•expected benefits from the 2020 Cauchari Transaction;

•accuracy of development budget and construction estimates; and

•preparation of a development plan for lithium production at the Thacker Pass Project.

Although the Company believes that the assumptions and expectations reflected in such forward-looking information are reasonable, LAC can give no assurance that these assumptions and expectations will prove to be correct, and since forward-looking information inherently involves risks and uncertainties, undue reliance should not be placed on such information.

Readers are cautioned that the foregoing lists of factors are not exhaustive. The forward-looking information contained in or incorporated by reference in this Prospectus is expressly qualified by these cautionary statements. All forward-looking information in this Prospectus speaks as of the date of this Prospectus. The Company does not undertake any obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, except as required by law. Additional information about these assumptions and risks and uncertainties is contained in the Company's filings with securities regulators, including the Company's most recent annual information form and most recent management's discussion and analysis for our most recently completed financial year and, if applicable, interim financial period, which are available on SEDAR at www.sedar.com and EDGAR at www.sec.gov.

NOTICE REGARDING REPRESENTATION OF MINERAL RESERVE AND MINERAL RESOURCE ESTIMATES

The disclosure included in or incorporated by reference in this Prospectus uses mineral reserves and mineral resources classification terms that comply with reporting standards in Canada and the mineral reserves and mineral resources estimates are made in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") - Definition Standards for Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Definition Standards"), and 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 mineral reserves and mineral resources estimates included in or incorporated by reference in this Prospectus have been prepared in accordance with NI 43-101 and the CIM Definition Standards. These standards differ significantly from the requirements of the SEC set out in SEC Industry Guide 7 ("SEC Industry Guide 7"). In particular, SEC Industry Guide 7 applies different standards in order to classify mineralization as a mineral reserve. As a result, the definitions of "proven mineral reserves" and "probable mineral reserves" used in NI 43-101 differ from the definitions in SEC Industry Guide 7. Under SEC Industry Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under SEC Industry Guide 7. Accordingly, mineral reserves estimates included in or incorporated by reference in this Prospectus may not qualify as "reserves" under SEC Industry Guide 7.

In addition, this Prospectus and the documents incorporated by reference herein use the terms “mineral resources,” “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources” to comply with the reporting standards in Canada. SEC Industry Guide 7 does not recognize mineral resources and U.S. companies are generally not permitted to disclose resources in documents they file with the SEC. “Inferred mineral resources” have a great amount of uncertainty as to whether they can be mined legally or economically. In accordance with Canadian rules, estimates of “inferred mineral resources” cannot form the basis of feasibility or pre-feasibility studies. Although generally speaking it can be assumed that with further work and the application of modifying factors all mineral resources are upgradeable, investors are cautioned not to assume that all or any part of the “mineral resources,” “measured mineral resources,” “indicated mineral resources” or “inferred mineral resources” reported in this Prospectus and the documents incorporated by reference herein will ever be upgraded to a higher category. Investors are also cautioned not to assume that any part of the “mineral resources,” “measured mineral resources,” “indicated mineral resources” or “inferred mineral resources” reported in this Prospectus and the documents incorporated by reference herein are economically or legally mineable. In addition, the definitions of “proven mineral reserves” and “probable mineral reserves” under reporting standards in Canada differ in certain respects from the standards of SEC Industry Guide 7. For the above reasons, information included in this Prospectus and the documents incorporated by reference herein that describes the Company’s mineral reserves and mineral resources estimates is not comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC under SEC Industry Guide 7. 

- 4 -

The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC.  These amendments became effective February 25, 2019 (the "SEC Modernization Rules") and, following a two-year transition period, the SEC Modernization Rules will replace the historical property disclosure requirements for mining registrants that are included in SEC Industry Guide 7.  Following the transition period, as a foreign private issuer that files its annual report on Form 40-F with the SEC pursuant to the MJDS, 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 Definition 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 MJDS, then the Company will be subject to the SEC Modernization Rules which differ from the requirements of NI 43-101 and the CIM Definition Standards.

The Company has filed with the SEC a registration statement on Form F-10 under the United States Securities Act of 1933, as amended, with respect to the Securities. This Prospectus, which forms a part of the registration statement, does not contain all of the information set forth in the registration statement, certain parts of which have been omitted in accordance with the rules and regulations of the SEC. For further information with respect to the Company and the Securities offered in this Prospectus, reference is made to the registration statement and to the schedules and exhibits filed therewith.

ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES AND AGENT FOR SERVICE OF PROCESS

The Company is a corporation incorporated under and governed by the BCBCA. Some of the directors and officers of the Company, and some of the experts named in this Prospectus, are residents of Canada or otherwise reside outside the United States, and all or a substantial portion of their assets, and a certain portion of the Company's assets, are located outside the United States. The Company has appointed an agent for service of process in the United States, but it may be difficult for investors who reside in the United States to effect service of process upon these persons in the United States, or to enforce a U.S. court judgment predicated upon the civil liability provisions of the U.S. federal securities laws against the Company or any of these persons. There is substantial doubt whether an action could be brought in Canada in the first instance predicated solely upon U.S. federal securities laws.

Daniel Weber, Marek Dworzanowski, Anthony Sanford, John Young, Andrew Hutson and Rene LeBlanc, each a "qualified person" under NI 43-101 who has prepared or supervised the preparation of certain scientific and technical information contained or incorporated by reference in this Prospectus, reside outside of Canada. Eight of our directors, Jonathan Evans, Dr. Michael Fischer, Dr. Yuan Gao, George Ireland, John Kanellitsas, Franco Mignacco, Gabriel Marcelo Rubacha and Xiaoshen Wang, reside outside of Canada, and each has appointed the Company as their agent for service of process in Canada at its office address: 300-900 West Hastings Street, Vancouver, British Columbia, Canada, V6C 1E5. Purchasers are advised that it may not be possible for investors to enforce judgements 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 in Canada.

THE COMPANY

The Company was incorporated under the BCBCA on November 27, 2007 under the name "Western Lithium Canada Corporation". On May 31, 2010, the Company changed its name to "Western Lithium USA Corporation". The Company amended its Articles in 2013 to add advance notice requirements for the election of directors and in 2015 to give the Board of Directors the authority by resolution to alter the Company's authorized share capital and to effect amendments to the Articles, except as otherwise specifically provided in the Articles or the BCBCA. On March 21, 2016, the Company changed its name to "Lithium Americas Corp.". On November 8, 2017, the Company completed the Consolidation.

The Company's head and registered office is located at 300-900 West Hastings Street, Vancouver, British Columbia, Canada, V6C 1E5.

BUSINESS OF THE COMPANY

LAC is a Canadian based resource company focused on advancing two significant lithium development projects, the Cauchari-Olaroz Project, located in the Province of Jujuy in Argentina, and the Thacker Pass Project, located in north-western Nevada, USA.

Project Overview

Cauchari-Olaroz Project

The Cauchari-Olaroz Project is a lithium development project located in Juyjuy Province, Argentina. The Cauchari-Olaroz Project is a joint venture owned and operated by LAC and Ganfeng. In 2019, a definitive feasibility study (and accompanying NI 43-101 technical report) was completed for the Cauchari-Olaroz Project that provides for development of a mining and processing operation at site for the production of 40,000 tonnes per annum of battery-quality lithium carbonate over a 40 year period. The Cauchari-Olaroz Project is currently in the midst of project development.

In early July, the Company announced a temporary suspension of non-essential construction activities at the Cauchari-Olaroz Project as a health and safety measure in response to workers testing positive for COVID-19. As of the date of this Prospectus, all workers who tested positive in July have recovered and were released from isolation.

Construction activities at the Cauchari-Olaroz Project have resumed with enhanced COVID-19 protocols. Progress continues at site with focus on the carbonate plant civil works and the lime plant construction. All critical equipment remains on track to be delivered by the end of 2020. The Company continues to assess the impact of COVID-19 on the construction schedule. Based on the current remobilization plan, which follows health and safety guidelines requiring a significantly reduced workforce at site, the Company expects construction to be complete by the end of 2021 with production in early 2022.

Capital costs remain unchanged at US$565 million, on a 100% basis, including the contingency. As of September 30, 2020, over 60% of the capital costs have been spent with over 80% committed. In addition, the Company recently completed a detailed review to confirm operating cost assumptions based on the 2019 definitive feasibility study estimates remain less than US$3,600/t of battery-quality lithium carbonate.

On October 19, 2020, the Company filed the Cauchari TR. The Cauchari TR provides updated information from the NI 43-101 technical report filed in connection with the 2019 definitive feasibility study, which technical report is summarized in the 2019 AIF, 2019 Annual MD&A and 2020 Q2 Interim MD&A, to reflect the more advanced status of construction, the most recent estimate for completion of construction and the consequent changes to the economic analysis derived from these inputs. Capital expenditures remained unchanged at US$565 million, with US$304 million already spent as at June 30, 2020 and excluded from the NPV. Operating costs were updated to US$3,579 per tonne of battery-quality lithium carbonate from US$3,576 per tonne previously. The Cauchari TR resulted in after-tax NPV of US$1.5 billion at 10% discount rate and US$12,000/tonne long-term lithium carbonate price. Sensitivity analysis demonstrates after-tax NPV of US$518 million at 50% lower lithium carbonate prices and US$3.4 billion at 50% higher prices. The Cauchari TR otherwise reaffirms the mineral resource and mineral reserve estimates contained in the 2019 technical report filed in connection with the 2019 definitive feasibility study.

- 9 -

As of September 30, 2020, the Company had US$54 million in cash in addition to US$202 million in capital available from credit and loan facilities to fund the Company’s share of the Cauchari-Olaroz Project. The Company remains fully-funded to advance the Cauchari-Olaroz Project to production and expects to have excess liquidity available under its credit facilities.

Thacker Pass Project

The Thacker Pass Project is located in northern Humboldt County, Nevada and hosts a large sedimentary-based lithium mineral resource. In 2018, LAC completed a pre-feasibility study on the Thacker Pass Project. The mine plan in the pre-feasibility study contemplates developing an initial phase 1 production capacity of 30,000 tonnes per annum of battery-grade lithium carbonate, followed by an expansion to 60,000 tonnes per annum.

In 2019, LAC commenced work on a feasibility study. For the feasibility study, LAC is investigating different production parameters that will result in a different financial analysis to that of the pre-feasibility study. The feasibility study is expected to be accompanied by an updated resource estimate that incorporates exploration data from prior drilling and analysis on lands hosting sedimentary-based mineralization proximate to the current resource area, which is expected to result in a substantial increase to indicated and measured resources at the Thacker Pass Project.

Permitting continues to advance as planned at the Thacker Pass Project with all major permits expected to be received by the end of the first quarter of 2021. The U.S. Bureau of Land Management (“BLM”) recently completed a 45-day public comment period on the Draft Environmental Impact Statement (“EIS”) as published by the BLM in the third quarter of 2020. The BLM is in the process of incorporating public comments into the Final EIS which will form the basis of the Record of Decision.

In September, the Nevada Governor’s Office of Economic Development unanimously approved tax abatements for the Thacker Pass Project which are expected for the first phase construction period. The tax abatements total US$9 million, including partial sales, property and payroll tax abatements.

The Company continues to explore financing options for the construction of the Thacker Pass Project, including the possibility of a joint venture partner. Based on discussions with potential customers and joint venture partners, the Company is assessing changes to the parameters of its feasibility study work to target a higher production capacity than the 20,000 tonnes per annum of lithium carbonate equivalent and a revised product mix than previously considered. As a result, the scheduled timing for completion of the feasibility study will be adjusted once the Company has determined the targeted initial capacity and product mix that more accurately reflects forecasted market demand. 

Detailed Project Descriptions

The BCBCA and the Company's articles provide that the rights and restrictions attached to any class of shares may not be modified, amended or varied unless consented to by special resolution passed by not less than two-thirds of the votes cast in person or by proxy by holders of shares of that class.

The holders of the Common Shares are entitled to: (i) notice of and to attend any meetings of shareholders and shall have one vote per Common Share at any meeting of shareholders of the Company; (ii) dividends, if as and when declared by the Board of Directors; and (iii) upon liquidation, dissolution or winding up of the Company, on a pro rata basis, the net assets of the Company after payment of debts and other liabilities.

Dividend Policy

The Company has no fixed dividend policy and the Company has not declared any dividends on its Common Shares since its incorporation. The Company anticipates that all available funds will be used to undertake exploration and development programs on its mineral properties as well as for the acquisition of additional mineral properties. The payment of dividends in the future will depend, among other things, upon the Company's earnings, capital requirements and operating and financial condition. Generally, dividends can only be paid if a corporation has retained earnings. There can be no assurance that the Company will generate sufficient earnings to allow it to pay dividends.

This Prospectus may also, from time to time, relate to the offering of Securities by way of a secondary offering by certain selling securityholders, including affiliates of Bangchak and Ganfeng pursuant to their respective rights set out in the applicable investor rights agreement referred to under "Plan of Distribution". The terms under which the Securities will be offered by selling securityholders will be described in the Prospectus Supplement. In connection with any secondary offering, in respect of any selling securityholder that is resident outside of Canada, the Company will file a non-issuer's submission to jurisdiction form on behalf of such selling securityholder with the corresponding Prospectus Supplement. The Prospectus Supplement for, or including, any offering of the Securities by selling securityholders will include, without limitation, where applicable:

- 16 -

•the names of the selling securityholders;

•the number or amount of Securities owned, controlled or directed by each of the selling securityholders;

•the number or amount of Securities being distributed for the account of each selling securityholder;

•the number or amount of Securities to be owned, controlled or directed by each of the selling securityholders after the distribution, and the percentage that number or amount represents out of the total number or amount of outstanding Securities of the class or series being distributed;

•whether the Securities are owned by the selling securityholders both of record and beneficially, of record only, or beneficially only;

•if the selling securityholder purchased any of the Securities held by it in the two years preceding the date of the Prospectus Supplement, the date or dates the selling securityholder acquired the Securities; and

•if the selling securityholder acquired the Securities held by it in the 12 months preceding the date of the Prospectus Supplement, the cost thereof to the selling securityholder in the aggregate and on an average cost-per-security basis.

PLAN OF DISTRIBUTION

The Company or a selling securityholder may, during the 25-month period that this Prospectus remains effective, offer for sale and issue, as applicable, the Securities, separately or together: (i) through underwriters, dealers or agents purchasing as principal or acting as agent; (ii) directly to one or more purchasers, including sales upon the exercise of conversion or exchange rights attaching to convertible or exchangeable securities held by the purchaser; or (iii) through a combination of any of these methods of sale. Securities sold to the public pursuant to this Prospectus may be offered and sold exclusively in Canada or the United States, or in both jurisdictions. The Prospectus Supplement relating to each offering of Securities will indicate the jurisdiction or jurisdictions in which such offering is being made to the public, identify each underwriter, dealer or agent, as the case may be, and will also set forth the terms of that offering, including the purchase price or prices of the Securities (or the manner of determination thereof if offered on a non- fixed price basis), the proceeds to the Company or, if applicable, the selling securityholder(s) and any underwriters', dealers' or agents' fees, commissions or other items constituting underwriters' or agents' compensation. Only underwriters, dealers or agents so named in the applicable Prospectus Supplement are deemed to be underwriters, dealers or agents, as the case may be, in connection with the Securities offered thereby. A Prospectus Supplement may provide that the Securities sold thereunder will be "flow-through" 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" as defined in NI 44-102, including sales made directly on the TSX, the NYSE or other existing trading markets for the securities. The prices at which the Securities may be offered may vary 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 offering price may be decreased and thereafter further changed, from time to time, to an amount not greater than the initial 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.

Any offering of Preferred Shares, Debt Securities, Subscription Receipts, Warrants or Units will be a new issue of Securities with no established trading market. Unless otherwise specified in the applicable Prospectus Supplement, Preferred Shares, Debt Securities, Subscription Receipts, Warrants and Units will not be listed on any securities exchange. There is no market through which the Securities, other than the Common Shares, may be sold and purchasers may not be able to resell such Securities purchased under this Prospectus and any applicable Prospectus Supplement. 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. See "Risk Factors".

- 17 -

Underwriters, dealers or agents may make sales of Securities in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an "at-the-market distribution" and subject to limitations imposed by and the terms of any regulatory approvals required and obtained under, applicable Canadian securities laws, which includes sales made directly on an existing trading market for the Common Shares, or sales made to or through a market maker other than on an exchange. In connection with any offering of Securities, except with respect to "at-the-market distributions" or as otherwise set out in a Prospectus Supplement relating to a particular offering of Securities, the underwriters, dealers or agents may over-allot or effect transactions which are intended to stabilize or maintain the market price of the offered Securities at a level other than that which might otherwise prevail in the open market. Such transactions may be commenced, interrupted or discontinued at any time. No underwriter, dealer or agent involved in an "at-the-market distribution", no affiliate of such an underwriter, dealer or agent and no person or company acting jointly or in concert with such an underwriter, dealer or agent may, in connection with the distribution, enter into any transaction that is intended to stabilize or maintain the market price of the Securities distributed, including selling an aggregate number or principal amount of securities that would result in the underwriter, dealer or agent creating an over-allocation position in the Securities distributed.

If underwriters or dealers purchase Securities as principals, the Securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed offering price or at varying prices determined at the time of sale. The obligations of the underwriters or dealers to purchase those Securities will be subject to certain conditions precedent, and the underwriters or dealers will be obligated to purchase all the Securities offered by the Prospectus Supplement if any of such Securities are purchased. If agents are used in an offering, unless otherwise indicated in the Prospectus Supplement, such agents will be acting on a "best efforts" basis for the period of their appointment. Any offering price and any discounts or concessions allowed or re-allowed or paid may be changed from time to time.

Under agreements which may be entered into by the Company and, if applicable, selling securityholder(s), underwriters, dealers and agents who participate in the distribution of Securities may be entitled to indemnification by the Company and, if applicable, selling securityholder(s), against certain liabilities, including liabilities under 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 and/or any selling securityholder in the ordinary course of business.

Under certain investor rights agreements, affiliates of Bangchak and Ganfeng have certain registration rights pursuant to which Common Shares or other Securities owned by them may be qualified for distribution under this Prospectus. The specific terms of any offering by any selling securityholder will be set out in the applicable Prospectus Supplement.

USE OF PROCEEDS

Unless otherwise specified in a Prospectus Supplement, the net proceeds from the sale of Securities will be used for general corporate purposes, including funding ongoing operations and/or working capital requirements, to repay indebtedness outstanding from time to time and for discretionary capital programs. Specific information about the use of the net proceeds to the Company of any offering of Securities under this Prospectus and the specific business objectives which the Company expects to accomplish with such proceeds will be set forth in the applicable Prospectus Supplement relating to that offering of Securities.

There may be circumstances where, based on results obtained or for other sound business reasons, a reallocation of funds may be necessary or prudent. Accordingly, management of the Company will have broad discretion in the application of the net proceeds of an offering of Securities. The actual amount that the Company spends in connection with each intended use of proceeds may vary significantly from the amounts specified in the applicable Prospectus Supplement and will depend on a number of factors, including those referred to under "Risk Factors" in this Prospectus and in the documents incorporated by reference herein and any other factors set forth in the applicable Prospectus Supplement. The Company may invest funds which it does not immediately use. Such investments may include short-term marketable investment grade securities denominated in Canadian dollars, United States dollars or other currencies. The Company may, from time to time, issue securities (including debt securities) other than pursuant to this Prospectus.

- 18 -

To date, the Company has not generated significant revenues from operations. The Company had negative operating cash flows for the year ended December 31, 2019 and for the six months ended June 30, 2020 and the Company may continue to incur negative operating cash flows. As a result, the Company may need to allocate a portion of its existing working capital or a portion of the proceeds of any offering of Securities to fund any such negative operating cash flow in future periods. See "Risk Factors - Negative Operating Cash Flows".

The Company will not receive any proceeds from any sale of Common Shares or other Securities by a selling securityholder.

TRADING PRICE AND VOLUME

The outstanding Common Shares are listed and posted for trading in Canada on the TSX and in the United States on the NYSE under the symbol "LAC". Trading prices and volumes of the Common Shares for the previous 12-month period will be provided, as required, in each Prospectus Supplement.

PRIOR SALES

Information in respect of prior sales of Common Shares and other Securities distributed under this Prospectus and for securities that are convertible into or exchangeable for Common Shares or such other Securities within the previous 12-month period will be provided, as required, in a Prospectus Supplement with respect to the issuance of Common Shares and/or other Securities pursuant to such Prospectus Supplement.

CERTAIN INCOME TAX CONSIDERATIONS

Owning any of the Securities may subject holders to tax consequences. The applicable Prospectus Supplement may describe certain material Canadian federal income tax considerations generally applicable to investors described therein of the acquisition, ownership and disposition of any Securities offered thereunder. The applicable Prospectus Supplement may describe certain United States federal income tax considerations generally applicable to investors described therein who are U.S. persons (within the meaning of the United States Internal Revenue Code of 1986, as amended) of the acquisition, ownership and disposition of any Securities offered thereunder. Prospective investors should consult their own tax advisors prior to deciding to purchase any of the Securities.

RISK FACTORS

An investment in the Securities is speculative and subject to a number of risks, including those set forth below and in the Company's then-current annual information form and in the then-current management's discussion and analysis for our most recently completed financial year and interim financial period, if applicable. Additional risk factors relating to a specific offering of Securities will be described in the applicable Prospectus Supplement.

Prospective investors should carefully consider these risks, in addition to the information contained and incorporated by reference herein and in the Prospectus Supplement relating to an offering and the information incorporated by reference therein, before purchasing Securities. Some of the risk factors described herein and in the documents incorporated by reference herein (including subsequently filed documents incorporated by reference herein), including the applicable Prospectus Supplement are interrelated and, consequently, investors should treat such risk factors as a whole. If any of the events identified in these risks and uncertainties were to actually occur, it could have a material adverse effect on the business, assets, financial condition, results of operations or prospects of the Company. These are not the only risks and uncertainties that the Company faces. Additional risks and uncertainties not presently known to the Company or that are currently considered immaterial may also have a material adverse effect on the business, assets, financial condition, results of operations or prospects of the Company. 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 risks described in this Prospectus or the applicable Prospectus Supplement or the documents incorporated by reference herein and therein or other unforeseen risks.

COVID-19 has Negatively Affected and is Expected to Further Negatively Affect the Company

In March 2020, COVID-19 was characterized as a pandemic by the World Health Organization. Since December 2019, COVID-19 has spread globally with a high concentration of cases in regions in which the Company conducts its business operations, including the United States, Canada and Argentina. The spread of COVID-19 and resulting tight government controls and travel bans implemented around the world, such as declarations of states of emergency, business closures, and manufacturing, commercial and/or other similar restrictions and limitations, have caused disruption to global supply chains and economic activity, and the market has entered a period of significantly increased volatility. Volatility and disruptions in the supply and demand for lithium and other metals and minerals, global supply chains and financial markets, as well as declining trade and market sentiment and reduced mobility of people, could affect commodity prices, interest rates, credit ratings, credit risk, share prices and inflation. To date, there have been a large number of temporary business closures, quarantines and a general reduction in business and consumer activity in a number of countries including the United States, Canada and Argentina. On March 20, 2020, following the Presidential decree for mandatory social isolation in Argentina, construction of the Cauchari-Olaroz Project was temporarily suspended. Engineering, procurement and manufacturing of equipment, which was performed offsite, continued. In mid-April, in accordance with the governmental regulations allowing mining and construction activities to resume, the Cauchari-Olaroz Project gradually restarted construction activities, and increased the size of the camp, common areas and other infrastructure to accommodate social distancing by staff in accordance with established protocols. By the end of the second quarter of 2020, circulation of COVID-19 had intensified in the Province of Jujuy. As announced in early July by the Company, as a result of workers at the project testing positive for COVID-19, construction was immediately suspended. During July, testing of the workforce at the project was completed, and workers were demobilized from the site. Only the minimum required staff remained on-site to oversee care and maintenance activities. All workers who tested positive in July have since recovered and have been released from isolation. Construction activities at the Cauchari-Olaroz Project have resumed with enhanced COVID-19 protocols. The Company continues to work in close cooperation with the local communities, unions, its workforce and the Province of Jujuy, Argentina as to the safety of its operations, and ongoing assessment and refinements to its pandemic-related operating protocols. Overall, COVID-19 has impacted the development program for the Cauchari-Olaroz Project over the last several months, including delays in delivery of equipment, limitations on operations as a result of government directive and internal operating protocols and the temporary suspension of operations in connection with onsite cases and the implementation of enhanced protocols to manage infections on site. There is a risk that these factors, along with other factors, related to COVID- 19 may continue to affect the Cauchari-Olaroz Project until the virus is brought under control in Argentina and globally, generally thought to be through the development and widespread use of a vaccine, and societal functioning is generally restored. There is also a risk that the severity of some or all of these matters as they relate to the Cauchari-Olaroz Project may increase in the future. 

Sustained disruption to development operations due to COVID-19, including future negative developments related to COVID-19 and governmental response to it, could have a material adverse effect on the project, including delays in the development timeline, an increase in development costs or a longer term suspension in the development of the project itself. There can be no assurance that a governmental directive similar to the Argentinian Presidential decree in March will not be issued in the future, that mining and construction activities will continue to be deemed essential businesses or that mining and construction activities will not otherwise be suspended in the future if COVID-19 continues to persist or there is a resurgence in Argentina, the United States, Canada or globally. The risks to the Company of COVID-19 also include restrictions, limitations and other effects on activities which may result in delays in obtaining requisite permitting for, completing a definitive feasibility study for and securing financing for the construction of the Thacker Pass Project and otherwise delay bringing the Thacker Pass Project to commercial production. Additional risks include the potential for the impairment of the Company’s assets or write-downs in respect of the Company’s material properties, or any part thereof, as a result of prolonged delays, limitations or restrictions on activities at the Company’s properties due to COVID-19, risks to employee health and safety, increased costs, including those related to labour and fuel and any additional capital being required related to bringing the Company’s projects to commercial production, regulatory changes, political or economic instabilities, civil unrest, and the availability of industry experts and personnel. The spread of COVID-19 is currently having an adverse impact on the global economy, the severity and duration of which are difficult to predict, and has adversely affected and may have further adverse effects on our performance, as well as our ability to successfully execute our operations, business strategies and initiatives. At this time, the full extent to which the COVID-19 pandemic will or may impact the Company remains uncertain and these factors are beyond the Company’s control.

The Potential Impact of COVID-19 Continues to be Uncertain

COVID-19 has significantly impacted health and economic conditions throughout Canada, the United States, Argentina and globally. The global spread of COVID-19 has been, and continues to be, complex and rapidly evolving, with governments, public institutions and other organizations imposing or recommending, and businesses and individuals implementing, restrictions on various activities or other actions to combat its spread, such as travel restrictions and bans, social distancing, quarantine or shelter-in-place directives, limitations on the size of gatherings, and closures of non-essential businesses. These restrictions have disrupted and may continue to disrupt economic activity, resulting in reduced commercial and consumer confidence and spending, increased unemployment, closure or restricted operating conditions for businesses, volatility in the global economy, instability in the credit and financial markets, labor shortages, regulatory recommendations to provide relief for impacted constituents, and disruption in supply chains.

The full extent to which COVID-19 impacts the Company's business, operations, financial position, results of operations and prospects is highly uncertain and will depend on numerous evolving factors that we may not be able to accurately predict or assess, including, but not limited to, the severity, extent and duration of the pandemic or any resurgences in the future, including any economic recession resulting from the pandemic, the development of effective vaccines and treatments, and the continued governmental, business and individual actions taken in response to the pandemic. Impacts related to COVID-19 are expected to continue to pose risks to the Company's business for the foreseeable future, may heighten many of the risks and uncertainties identified in this Prospectus, and could have a material adverse impact on the Company's business, operations, financial position, results of operations or prospects in a manner that is difficult to predict.

There is No Market for the Securities

Unless otherwise specified in the applicable Prospectus Supplement, the Preferred Shares, Debt Securities, Subscription Receipts, Warrants and Units will not be listed on any securities exchange. There is no market through which the Securities, other than the Common Shares, may be sold and purchasers may not be able to resell such Securities purchased under this Prospectus and any applicable Prospectus Supplement. 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.

Dilution from Further Financings

The Company may need to raise additional financing in the future through the issuance of additional equity securities or convertible debt securities. If the Company raises additional funding by issuing additional equity securities or convertible debt securities, such financings may substantially dilute the interests of shareholders of the Company and reduce the value of their investment and the value of the Company's securities.

Active Liquid Market for Common Shares

There may not be an active, liquid market for the Common Shares. There is no guarantee that an active trading market for the Common Shares will be maintained on the TSX and/or the NYSE. Investors may not be able to sell their Common Shares quickly or at the latest market price if trading in the Common Shares is not active.

Discretion in the Use of Proceeds

Management will have broad discretion concerning the use of the net proceeds from the offering of any Securities, as well as the timing of their expenditures. Depending on fluctuations in lithium prices and other factors, the intended use of net proceeds from the offering of any Securities may change. As a result, an investor will be relying on the judgment of management for the application of the net proceeds from the offering of any Securities. Management may use the net proceeds from the offering of any Securities in ways that an investor may not consider desirable if they believe it would be in the best interests of the Company to do so. The results and the effectiveness of the application of proceeds from an offering of any Securities are uncertain. If the proceeds are not applied effectively, the Company's business, financial condition, results of operations or prospects may suffer.

- 21 -

Negative Operating Cash Flows

To date, the Company has not generated significant revenues from operations. The Company had negative operating cash flows for the year ended December 31, 2019 and for the six months ended June 30, 2020 and the Company may continue to incur negative operating cash flows. As a result, the Company may need to allocate a portion of its existing working capital or a portion of the proceeds of any offering of Securities to fund any such negative operating cash flow in future periods.

LEGAL MATTERS

Unless otherwise specified in the Prospectus Supplement relating to a specific offering of Securities, certain legal matters relating to the offering of the Securities will be passed upon on behalf of the Company by Cassels Brock & Blackwell LLP with respect to matters of Canadian law. As at the date of this Prospectus, the partners and associates of Cassels Brock & Blackwell LLP, as a group, beneficially own, directly or indirectly, less than 1% of the outstanding securities of any class or series of the Company.

AUDITORS, TRANSFER AGENT AND REGISTRAR
