The Securities may be offered separately or together, in separate series, in amounts, at prices and on terms to be determined at the time of sale and set forth in one or more prospectus supplements (each, a "**Prospectus Supplement**"). This Prospectus qualifies the distribution of Securities by the Company. In addition, Securities may be offered and issued in consideration for the acquisition of other businesses, assets or securities by the Company or a subsidiary of the Company. The consideration for any such acquisition may consist of any of the Securities separately, a combination of Securities or any combination of, among other things, Securities, cash and assumption of liabilities.

The specific terms of any offering of Securities will be set out in the applicable Prospectus Supplement and may include, without limitation, where applicable: (i) in the case of Common Shares, the number of Common Shares being offered, the offering price (or the manner of determination thereof if offered on a non-fixed price basis), whether the Common Shares are being offered for cash, and any other terms specific to the Common Shares being offered; (ii) in the case of Preferred Shares, the designation of the particular class, series, liquidation preference amount, the number of Preferred Shares being offered, the offering price (or the manner of determination thereof if offered on a non-fixed price basis), whether the Preferred Shares are being offered for cash, the currency or currency unit for which such Preferred Shares may be purchased, any voting rights, any rights to receive dividends, any terms of redemption, any conversion or exchange rights, and any other terms specific to the Preferred Shares being offered; (iii) in the case of Debt Securities, the specific designation of the Debt Securities, whether such Debt Securities are senior or subordinated, the aggregate principal amount of the Debt Securities being offered, the currency or currency unit in which the Debt Securities may be purchased, authorized denominations, any limit on the aggregate principal amount of the Debt Securities of the series being offered, the issue and delivery date, the maturity date, the offering price (at par, at a discount or at a premium), the interest rate or method of determining the interest rate, the interest payment date(s), any conversion or exchange rights that are attached to the Debt Securities, any redemption provisions, any repayment provisions, and any other terms specific to the Debt Securities being offered; (iv) in the case of Subscription Receipts, the number of Subscription Receipts being offered, the offering price (or the manner of determination thereof if offered on a non-fixed price basis), whether the Subscription Receipts are being offered for cash, the terms, conditions and procedures for the exchange of Subscription Receipts for Common Shares and/or other securities of the Company, as the case may be, the currency or currency unit in which the Subscription Receipts are issued, and any other terms specific to the Subscription Receipts being offered; (v) in the case of Warrants, the number of Warrants being offered, the offering price (or the manner of determination thereof if offered on a non-fixed price basis), whether the Warrants are being offered for cash, the terms, conditions and procedures for the exercise of such Warrants into or for Common Shares and/or other securities of the Company, and any other terms specific to the Warrants being offered; and (vi) in the case of Units, the designation and terms of the Units and of the Securities comprising the Units, the offering price (or the manner of determination thereof if offered on a non-fixed price basis), whether the Units are being offered for cash, the currency or currency unit in which the Units are issued, and any other terms specific to the Units being offered. A Prospectus Supplement may include other specific terms pertaining to the Securities that are not within the alternatives and parameters described in this Prospectus. You should read this Prospectus and any applicable Prospectus Supplement carefully before you invest in any Securities.

All shelf information permitted under applicable securities legislation to be omitted from this Prospectus will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus, unless an exemption from the prospectus delivery requirements is available. Each Prospectus Supplement will be incorporated by reference into this Prospectus for the purposes of securities legislation as of the date of such Prospectus Supplement and only for the purposes of the distribution of the Securities to which such Prospectus Supplement pertains.

This Prospectus may qualify an "at-the-market distribution" as defined in NI 44-102. This Prospectus does not qualify for issuance Debt Securities, or Securities convertible into or exchangeable for Debt Securities, in respect of which the payment of principal and/or interest may be determined, in whole or in part, by reference to one or more underlying interests including, for example, an equity or debt security, a statistical measure of economic or financial performance including, but not limited to, any currency, consumer price or mortgage index, or the price or value of one or more commodities, indices or other items, or any other item or formula, or any combination or basket of the foregoing items. For greater certainty, this Prospectus may qualify for issuance Debt Securities, or Securities convertible into or exchangeable for Debt Securities, in respect of which the payment of principal and/or interest may be determined, in whole or in part, by reference to published rates of a central banking authority or one or more financial institutions, such as a prime rate or bankers' acceptance rate, or to recognized market benchmark interest rates such as the Canadian Overnight Repo Rate Average ("**CORRA**") or a United States federal funds rate.

- ii -

We may offer and sell the Securities to or through underwriters or dealers purchasing as principals and may also sell the Securities to one or more purchasers directly or through agents designated by the Company from time to time. The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent, if any, engaged by the Company 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 the proceeds to us, 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. If Securities are offered on a non-fixed price basis, the underwriters', dealers' or agents' compensation will be increased or decreased by the amount by which the aggregate price paid for Securities by the purchasers exceeds or is less than the gross proceeds paid by the underwriters, dealers or agents to the Company. See "Plan of Distribution".

Unless otherwise specified in the relevant Prospectus Supplement, subject to applicable laws, in connection with any offering of Securities, other than an "at-the-market distribution", the underwriters, dealers or agents may over-allot or effect transactions that are intended to stabilize or maintain the market price of the offered Securities at levels other than those which otherwise might prevail on the open market. Such transactions, if commenced, may be 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. See "Plan of Distribution".

As at the date of this Prospectus, no underwriter, dealer or agent is in a contractual relationship with the Company requiring the underwriter, dealer or agent to distribute under this Prospectus. No underwriter, dealer or agent has been involved in the preparation of this Prospectus or performed any review of the contents of this Prospectus**.**

**Investors should rely only on the information contained in or incorporated by reference in this Prospectus and any applicable Prospectus Supplement. The Company has not authorized anyone to provide investors with different or additional information. There are certain risks inherent in an investment in our Securities and in our activities. Prospective investors should carefully read and consider the risk factors described or referenced under the headings "Forward-Looking Information" and "Risk Factors" in this Prospectus, contained in any of the documents incorporated by reference herein, and in any applicable Prospectus Supplement and any of the documents incorporated by reference therein, before purchasing Securities. See "Forward-Looking Information" and "Risk Factors" below and the "Risk Factors" section of the applicable Prospectus Supplement.**

**All dollar amounts in this Prospectus are in United States dollars, unless otherwise indicated. See "Currency and Exchange Rate Information".**

The outstanding Common Shares are listed and posted for trading in Canada on the TSX Venture Exchange ("**TSXV**") and in the United States on the NYSE American LLC ("**NYSE American**") under the trading symbol "SLI". On July 29, 2025, the last trading day prior to the date of this Prospectus, the closing price of the Common Shares on the TSXV was C$3.55 and on the NYSE American was US$2.59.

**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. See "Risk Factors" below and the "Risk Factors" section of the applicable Prospectus Supplement.**

- iii -

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

**We are permitted, under a multi-jurisdictional disclosure system adopted by the securities regulatory authorities in the United States and Canada ("MJDS"), to prepare this 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 as issued by the International Accounting Standards Board ("IFRS") and our interim financial statements in United States dollars and in accordance with IFRS as applicable to interim financial reporting, including IAS 34, Interim Financial Reporting ("IAS 34"), and they therefore may not be comparable to financial statements of United States companies.**

Such tax consequences, including for investors who are resident in, or citizens of, the United States and Canada, are not described in this Prospectus and may not be fully described in any applicable Prospectus Supplement. You should read the tax discussion in any Prospectus Supplement with respect to a particular offering of Securities and consult your own tax advisor with respect to your own particular circumstances.**

**Your ability to enforce civil liabilities under United States federal securities laws may be affected adversely because: (i) the Company is governed by the *Canada Business Corporations Act* ("CBCA"); (ii) certain officers, all but three of the directors and some of the experts named in this Prospectus are not residents of the United States; and (iii) 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 and Agent for Service of Process".**

Four directors and two officers of the Company and certain of the experts named in this Prospectus reside outside of Canada. See "Enforceability of Certain Civil Liabilities and Agent for Service of Process".

**ABOUT THIS PROSPECTUS**

This Prospectus provides a general description of the Securities that we may offer. Each time we 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. We have not authorized anyone to provide investors with different or additional information. If anyone provides you with different or additional information, you should not rely on it. We are not 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. 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, nor incorporated by reference herein.

Market data and certain industry forecasts used in the Prospectus and the documents incorporated by reference herein 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.

Unless we have indicated otherwise, or the context otherwise requires, references in this Prospectus and any Prospectus Supplement to "SLI", the "Company", "we", "us" and "our" refer to Standard Lithium Ltd. and/or, as applicable, one or more of its subsidiaries, its predecessors and/or its co-ownership arrangement.

Certain capitalized terms and other terms used in this Prospectus are defined in the "Glossary of Terms".

**FORWARD-LOOKING INFORMATION**

This Prospectus, including the documents incorporated herein by reference, contains certain "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", "target", "intend", "could", "might", "should", "believe", "scheduled", "implement" and similar words or 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: the Company's planned exploration and development programs (including, but not limited to, plans and expectations regarding testing and operation of the lithium extraction Demonstration Plant (as defined below)); commercial opportunities for lithium products, delivery of studies; the Company's strategic and ongoing partnerships, including with Equinor (as defined below); filing of technical reports; expected results of exploration; accuracy of mineral or resource exploration activity; accuracy of mineral reserves or mineral resources estimates, including the ability to develop and realize on such estimates; whether mineral resources will ever be developed into mineral reserves, and information and underlying assumptions related thereto; budget estimates and expected expenditures by the Company on its properties; regulatory or government requirements or approvals; the reliability of third party information; continued access to mineral properties or infrastructure, payments and share issuances pursuant to property agreements; fluctuations in the market for lithium and its derivatives; expected timing of the expenditures; performance of the Company's business and operations; changes in exploration costs and government regulation in Canada and the United States; competition for, among other things, capital, acquisitions, undeveloped lands and skilled personnel; changes in commodity prices and exchange rates; currency and interest rate fluctuations; inflation, the Company's funding requirements and ability to raise capital; geopolitical instability; war (such as Russia's invasion of Ukraine and the ongoing conflict in the Middle East) and other factors or information.

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, which 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; the ability to fund, advance and develop the Company's properties; the Company's ability to operate in a safe and effective manner; uncertainties with respect to receiving, and maintaining, mining, exploration, environmental and other permits; pricing and demand for lithium, including that such demand is supported by growth in the electric vehicle market and the energy storage market; impact of increasing competition; commodity prices, currency rates, interest rates and general economic conditions; the legislative, regulatory and community environments in the jurisdictions where the Company operates; impact of unknown financial contingencies; market prices for lithium products; budgets and estimates of capital and operating costs; estimates of mineral resources and mineral reserves; reliability of technical data; the ability to negotiate access agreements on commercially reasonable terms and the anticipated timing and results of operation and development. Although the Company believes that the assumptions and expectations reflected in such forward-looking information are reasonable, the Company can give no assurance that these assumptions and expectations will prove to be correct. Since forward-looking information inherently involves risks and uncertainties, undue reliance should not be placed on such information.

Forward-looking information involves known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking information. Such factors include, but are not limited to, factors relating to: general economic conditions in Canada, the United States and globally; industry conditions, including the state of the electric vehicle market and the energy storage market; governmental regulation of the mining industry, including environmental regulation; geological, technical and drilling problems; changes in current and future trade agreements, legislation, regulations, import tariffs and other similar trade barriers, including material changes in the U.S.-Mexico-Canada agreements and implementation of the "America First Trade Policy"; geo-political tension and tension with respect to lithium; unanticipated operating events; negotiation of commercial access agreements; competition for and/or inability to retain drilling rigs and other services and to obtain capital, undeveloped lands, skilled personnel, equipment and inputs; reliance on third parties; potential or ongoing joint ventures; the availability of capital on acceptable terms; the need to obtain required approvals from regulatory authorities; 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; 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 unknown financial contingencies, including litigation costs, on the Company's operations; 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; intellectual property risk; stock market volatility; volatility in market prices for commodities; liabilities inherent in the mining industry; inflation risks; risks related to war (such as Russia's invasion of Ukraine and the ongoing conflict in the Middle East); changes in tax laws, royalty policies and incentive programs relating to the mining industry; other risks pertaining to the mining industry; conflicts of interest; dependency on key personnel; and fluctuations in currency and interest rates, as well as those factors discussed in the section entitled "Risk Factors" in this Prospectus and in the AIF (as defined herein). Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results to differ from those anticipated, estimated or intended.

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 or incorporated by reference in this Prospectus speak as of the date of this Prospectus (or as of the date in the document incorporated by reference). 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, including the documents incorporated by reference herein, 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 AIF and most recent management's discussion and analysis for our most recently completed financial period and, if applicable, interim financial period, which are available on SEDAR+ at <u>www.sedarplus.com</u> and EDGAR at <u>www.sec.gov</u>.

**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 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 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 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.

**ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES AND AGENT FOR SERVICE OF PROCESS**

**Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person that resides outside of Canada, even if the party has appointed an agent for service of process.**

Your ability to enforce civil liabilities under United States federal securities laws may be affected adversely because: (i) the Company is governed by the CBCA; (ii) certain officers, all except three of the directors and some of the experts named in this Prospectus are not residents of the United States; and (iii) 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. 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 the Company or 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.

The Company will file with the SEC, concurrently with the registration statement on Form F-10 of which this Prospectus forms a part, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Company will appoint Puglisi & Associates, with an address at 850 Library Ave Unit 204, Newark, DE 19711, United States , 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 of Securities under the registration statement on Form F-10.

**THE COMPANY**

The Company was incorporated under the laws of the Province of British Columbia on August 14, 1998 under the name "Tango Capital Corp." On April 7, 1999, the Company changed its name to "Patriot Capital Corp." and to "Patriot Petroleum Corp." effective March 5, 2002. At its annual general meeting held on November 3, 2016, the shareholders of the Company approved the change of name of the Company to "Standard Lithium Ltd." and the continuance of the Company from the *Business Corporations Act* (British Columbia) to the CBCA. On December 1, 2016, the Company completed the name change and continuation.

The Company's registered office is located at Suite 2200, 885 West Georgia Street, Vancouver, British Columbia, V6C 3E8. The Company's head office is located at Suite 1625, 1075 West Georgia Street, Vancouver, British Columbia, V6E 3C9.

**BUSINESS OF THE COMPANY**

The Company is a near-commercial lithium company focused on the sustainable development of a portfolio of lithium-brine bearing properties in the U.S. The Company prioritizes brine projects characterized by high-grade resources, robust infrastructure, skilled labor, and streamlined permitting, and aims to achieve sustainable, commercial-scale lithium production via the application of scalable and fully integrated Direct Lithium Extraction ("**DLE**") and purification processes. Recognized as a critical mineral by the U.S. Department of Energy ("**DOE**"), lithium holds strategic importance for the rapidly expanding sectors of electric vehicles and energy storage systems, further influencing the broader economy and national security.

The Company's flagship project, the South West Arkansas Project (as defined below), is located on the Smackover Formation in southern Arkansas, a region with a long-standing and established industry of mineral extraction and national security. The Company is also developing prospective lithium brine areas within the Smackover Formation in East Texas (the "**East Texas Properties**"), in conjunction with Equinor ASA, a multi-national energy company ("**Equinor**"), and continuing to evaluate the potential for commercial development of the LANXESS Property Project (as defined below).

The Company operates its first-of-a-kind industrial-scale DLE demonstration plant (the "**Demonstration Plant**") at LANXESS' South plant in southern Arkansas (the "**LANXESS Property Project**", and together with the South West Arkansas Project, the "**Arkansas Lithium Projects**"). The Demonstration Plant has been used for proof-of-concept and commercial feasibility studies.

The South West Arkansas Project, being developed in partnership with Equinor, encompasses a significant land area of over 27,000 net mineral acres and is a key project in the Company's portfolio due to its scale and quality of lithium-brine resources. The Company completed and published a Preliminary Feasibility Study ("**PFS**") in September of 2023 for the South West Arkansas Project. A Definitive Feasibility Study ("**DFS**") and a Front-End Engineering Study ("**FEED**") are currently underway for the South West Arkansas Project. Construction is targeted to begin in 2025, with first production expected in 2028, subject to, among other things, continued project definition, due diligence, available financing, and positive DFS results.

The Company, in partnership with Equinor, is also developing the East Texas Properties. The Company published exploration drilling results and testing in October of 2023, which demonstrated lithium concentrations of 644 mg/L on average. In partnership with Equinor, the Company plans to continue securing further leasehold positions and to perform further exploration drilling in East Texas, and will pursue developing a resource assessment for the project area. The Equinor Transaction (as defined below) includes a total investment of up to $160 million, reflecting a 45% ownership stake in each of the South West Arkansas Project and the East Texas Properties.

In addition, the Company also has an interest in certain mineral leases located in the Mojave Desert in San Bernardino County, California.

**Project Overview**

*Arkansas Lithium Projects*

The Arkansas Lithium Projects consist of two independent development properties: the South West Arkansas Project and the LANXESS Property Project. The South West Arkansas Project, developed in collaboration with Equinor, is central to the Company's portfolio.

The resource development of brine leases located in southwest Arkansas (the "**South West Arkansas Project**") is maintained pursuant to an option agreement dated December 29, 2017 between Tetra Technologies Inc. ("**TETRA**") and the Company (the "**TETRA 1st Option Agreement**") to acquire certain rights to conduct brine exploration and production and lithium extraction activities on approximately 27,262 net mineral acres of brine leases and deeds located in Columbia and Lafayette Counties, Arkansas.

Under the TETRA 1st Option Agreement, the Company paid TETRA $500,000 on January 28, 2018, $600,000 by December 29, 2018, $700,000 on January 31, 2020, and $750,000 on December 29, 2020. Under the TETRA 1st Option Agreement, the Company is required to pay additional annual payments of $1,000,000 by each annual anniversary date beginning on the date that is 48 months following the date of the TETRA 1st Option Agreement, until the earlier of the expiration of 10 years from the date of the TETRA 1<sup>st</sup> Option Agreement or the execution of a limited mineral assignment, or, if the Company exercises the option. During the lease period, as specified in the TETRA 1st Option Agreement, at any time following the commencement of commercial production of the lithium, the Company agreed to pay a royalty of 2.5% (minimum royalty of $1,000,000) to TETRA. On October 31, 2023, the Company exercised its option to acquire brine production rights pursuant to the TETRA 1st Option Agreement at the South West Arkansas Project.

All of the Company's activities in southern Arkansas relate to brine leases that overlie the Smackover Formation in a region with a long history of commercial scale brine processing. Historical published brine data and current unpublished brine data from within and adjacent to the Company's two areas of interest lead the Company to believe that lithium-bearing brines are present.

The South West Arkansas Project brine lease area has been historically drilled for oil and gas exploration, and approximately 2,041 exploration and production wells have been completed in the Smackover Formation in or immediately adjacent to the Company's lease area. A portion of these wells had available petro-physical logs of the Smackover Formation brine-bearing zone. On January 28, 2019, the Company announced a maiden inferred mineral resource of 802,000 tonnes lithium carbonate equivalent ("**LCE**") at the South West Arkansas Project.

On October 12, 2021, the Company announced the results of a preliminary economic assessment ("**PEA**") and updated inferred mineral resource estimate on the South West Arkansas Project. The results of the PEA led to the commencement of a PFS at the South West Arkansas Project on May 12, 2022.

On August 8, 2023, the Company announced the results of the PFS on the South West Arkansas Project. On September 18, 2023, the Company filed a PFS and updated inferred mineral resource for its South West Arkansas Project, available under the Company's SEDAR+ profile at www.sedarplus.com. On July 30, 2025, the Company filed the amended and restated South West Arkansas Technical Report, available under the Company's SEDAR+ profile at www.sedarplus.com. Mineral resources, however, are not mineral reserves and do not have demonstrated economic viability. There is no guarantee that all or any part of a mineral resource will be converted into a mineral reserve.

On May 7, 2024, the Company entered into a strategic partnership with Equinor, involving a gross investment of up to $160 million across the South West Arkansas and East Texas Properties (the "**Equinor Transaction**") whereby Equinor acquired interests in two of the Company's formerly wholly-owned subsidiaries, one of which holds the South West Arkansas Project and the other holds the East Texas Properties. Pursuant to the terms of the Equinor Transaction, Equinor acquired a 45% interest in each of the subsidiaries for an initial cash payment of $30 million to the Company and the commitment to invest an additional $130 million as follows:

&nbsp;&nbsp;&nbsp;&nbsp;· Equinor agreed to solely fund the first $40 million
and $20 million in exploration and development costs for the South West Arkansas Project and the East Texas Properties, respectively,
after which all additional capital expenditures would be funded on a pro-rata basis; and

&nbsp;&nbsp;&nbsp;&nbsp;· The Company will receive $40 million in milestone
payments associated with the South West Arkansas Project and $30 million in milestone payments associated with the East Texas Properties
subject to final investment decisions being made by certain dates ()"**FID** ").

The Company will maintain majority ownership and operatorships pursuant to a development services agreement at each of the South West Arkansas Project and the East Texas Properties.

The LANXESS Property Project is maintained pursuant to a memorandum of understanding dated May 4, 2018 and subsequent joint venture term sheet dated November 9, 2018 with LANXESS, regarding the testing and proving of commercial viability of lithium extraction from brine that is produced as part of LANXESS' bromine extraction business at its three facilities in Union County, southern Arkansas.

The first phase of the Lanxess Property Project (the "**Lanxess 1A Project**") is located at the LANXESS South facility near El Dorado, Arkansas. The Company has also been successfully operating the Demonstration Plant at the Lanxess 1A Project location for over four years. The Demonstration Plant serves as a testing and optimization facility, refining the commercial blueprint for scalable and replicable DLE processes.

On September 6, 2023, the Company completed a DFS for the Lanxess 1A Project at the LANXESS Property Project. On October 18, 2023, the Company filed the Lanxess DFS technical report and measured and indicated resource for the LANXESS Property Project, available under the Company's SEDAR+ profile at <u>www.sedarplus.com</u>. On July 30, 2025, the Company filed the amended and restated Lanxess Technical Report, available under the Company's SEDAR+ profile at www.sedarplus.com. Mineral resources, however, are not mineral reserves and do not have demonstrated economic viability. There is no guarantee that all or any part of the mineral resource will be converted into a mineral reserve.

The Company is considering whether to advance towards an FID on the Lanxess 1A Project, with the timing contingent upon ongoing review of project commercialization potential. The Company does not anticipate moving forward with the Lanxess 1A Project unless and until it a more constructive lithium market and further project definition is established.

*East Texas Properties*

Pursuant to the Equinor Transaction, the Company and Equinor are developing and advancing mineral right acquisitions and exploration of prospective lithium brine areas at the East Texas Properties. The Company published exploration drilling results and testing on October 25, 2023, which demonstrated lithium concentrations of 644 mg/L on average, highlighting the potential for globally significant lithium resource concentrations in the areas the Company is exploring. In partnership with Equinor, the Company plans to continue securing further leasehold positions and to perform further exploration drilling on the East Texas Properties and will pursue developing a resource assessment for the project area that it expects to complete in 2025.

*Lithium Brine Processing R&D Project*

The Company is focused on continuously improving its lithium extraction and refining technologies through its technical group. This work centers on several areas: (i) pre-treating brines using filtration technologies; (ii) selectively extracting lithium from pre-treated brine to produce concentrated lithium salt solutions; (iii) purifying and crystallizing these solutions to produce battery-grade lithium products; and (iv) de-risking the technology by designing, building, and operating progressively larger pilot and pre-commercial plants.

As part of these efforts, the Company entered into the Joint Development Agreement with KTS (as defined below) to support the commercial deployment of its projects. In March 2024, the Company installed a commercial-scale lithium extraction column—referred to as a LiPRO™ Lithium Selective Sorption ("**LSS**") unit—at its Demonstration Plant near El Dorado, Arkansas. This column, supplied by KTS, is the same size and design as those planned for the Company's commercial projects, including the South West Arkansas Project.

On April 24, 2024, the Company announced that it had successfully commissioned a commercial-scale DLE column at its DLE facility, which is one of the largest continuously operating DLE facilities in North America. The Company further announced that during a representative period of continuous operation, the commercial-scale column exceeded design parameters, achieving an average lithium recovery of 97.3%.

The lithium extraction column has been integrated with the Demonstration Plant for testing and optimization. This step is intended to provide validation and information necessary for ongoing project financing processes, as well as for the FEED and DFS studies for the South West Arkansas Project.

This work, carried out at project sites and various other locations in the United States and Canada, supports the Company's efforts to advance its projects toward commercial-scale production.

*Carbon Capture Project*

On September 14, 2021, the Company announced that it was undertaking and funding a pilot project in southern Arkansas to test a novel carbon capture technology. The pilot project is being conducted with the owner of the technology, Aqualung Carbon Capture AS ("**Aqualung**"), and a pilot carbon capture unit was installed at a natural gas processing site in southern Arkansas owned and operated by Mission Creek Resources LLC. The pilot project will take a slipstream of flue gas for processing through the Aqualung pilot unit. The resulting concentrated carbon dioxide ("**CO<sub>2</sub>**") stream will then be used in the Company's ongoing research and development ("**R&D**") program to understand how CO<sub>2</sub> may be permanently sequestered by the Company as part of normal brine reinjection activities. This R&D program will then expand to consider how CO<sub>2</sub> may also be used as an alternative reagent at several points in the Company's process flowsheet.

The Company believes the patent-protected Aqualung carbon capture systems ("**CCS**") technology, developed by the Norwegian University of Science and Technology ("**NTNU**"), is an innovative approach with the ability to deliver a cost effective, scalable, modular decarbonization solution.

The Aqualung CCS technology results from over 20 years of research at NTNU and is based on a membrane system that selectively extracts CO<sub>2</sub> from a wide range of CO<sub>2</sub> sources emitted by hydrocarbon-burning energy sources. It produces a high purity CO<sub>2</sub> gas stream that can either be sequestered or reused.

The Company has invested $2.5 million in Aqualung as part of a $10 million strategic equity round that included Nasdaq listed, Golar LNG Limited, London-based shipowner, Global Ship Lease, Inc., and Geneva-based metals trading services group, MKS Pamp SA. Dr. Andrew Robinson, President and Chief Operating Officer of the Company also joined the board of Aqualung.

On January 31, 2023, the Company installed its carbon capture pilot plant in Southern Arkansas to assess sustainable production practices in collaboration with its investment partner, Aqualung.

**PLAN OF DISTRIBUTION**

The Company 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 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 TSXV, the NYSE American 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".

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, underwriters, dealers and agents who participate in the distribution of Securities may be entitled to indemnification by the Company 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 in the ordinary course of business.

**USE OF PROCEEDS**

Unless otherwise indicated in a Prospectus Supplement, we currently expect to use the net proceeds from the sale of Securities to fund our capital commitments to the South West Arkansas Project and the East Texas Properties as part of our joint ventures with Equinor, other potential capital projects, acquisitions, general corporate purposes, and for working capital– meaning current assets minus current liabilities. 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 United States dollars, Canadian dollars or other currencies. The Company may, from time to time, issue securities (including debt securities) other than pursuant to this Prospectus.

Any specific allocation of the net proceeds of an offering to a specific purpose will be determined at the time of the offering and will be described in the relevant Prospectus Supplement. To date, the Company has not generated revenues from operations. The Company had negative operating cash flows for the six month fiscal period ended December 31, 2024 and for the three months ended March 31, 2025 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".

**PRIOR FINANCINGS**

The Company filed a short form base shelf prospectus on July 27, 2023 and a subsequent prospectus supplement for an "at-the-market distribution" of up to $50,000,000 on November 17, 2023 (the "**ATM**"). As of June 30, 2025, the net proceeds of the ATM are approximately $39,720,318, after deducting fees associated with the ATM. The Company did not previously disclose a budget for the utilization of the proceeds of the offering, but did disclose that the proceeds were intended to be utilized to support the strategic development goals of the Company, and to pursue the following objectives:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Continue advancement of the working programs
at the South West Arkansas Project;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Continue advancement of the working programs
at the LANXESS Property Project;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Continue to develop and commercialize the Demonstration
Plant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Develop and advance mineral right acquisitions
and exploration of prospective lithium brine areas at the East Texas Properties; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Pursue strategic project acquisitions.

As of the date of this Prospectus, there have been no material variances to the use of proceeds previously announced, and the Company continues to utilize the proceeds of ATM in the achievement of these objectives.

**TRADING PRICE AND VOLUME**

The outstanding Common Shares are listed and posted for trading in Canada on the TSXV and in the United States on the NYSE American under the symbol "SLI". 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 AIF and in the then-current management's discussion and analysis for our most recently completed financial year period 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.

*Liquidity and Capital Resources*

At March 31, 2025, the Company had a cash balance of $31,568,529, a working capital surplus of $31,326,800 and current obligations of $5,677,612.

Historically, capital requirements have been primarily funded through the sale of Common Shares. Factors that could affect the availability of financing include the progress and results of ongoing exploration at the Company's mineral properties, the state of international debt and equity markets and investor perceptions and expectations of the global market for lithium and its derivatives. There can be no assurance that such financing will be available in the amount required at any time or for any period or, if available, that it can be obtained on terms satisfactory to the Company. Based on the amount of funding raised, the Company's planned exploration, development or other work programs may be postponed, or otherwise revised, as necessary.

*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 and Market Price of Securities*

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 TSXV and/or the NYSE American. 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.

Securities markets have a high level of price and volume volatility, and the market price of securities of many companies have experienced wide fluctuations in price which have not necessarily been related to the operating performance, underlying asset values or prospects of such companies. Securities of companies with small capitalization have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved. These risk factors included global economic and trade developments and market perceptions of the attractiveness of certain industries. There can be no assurance that continuing fluctuations in price will not occur. In addition, from time to time, the stock market experiences significant price and volume volatility that may affect the market price of the Common Shares for reasons unrelated to the Company's performance.

Other factors unrelated to the performance of the Company that may have an effect on the price of Common Shares include the following: lessening in trading volume and general market interest in the Company's securities may affect a purchaser's ability to trade significant numbers of Common Shares; and the size of the Company's public float may limit the ability of some institutions to invest in the Company's securities. The price per Common Share may be adversely affected by a variety of factors relating to the Company's business, including fluctuation in the Company's operating and financial results, the result of any public announcement made by the Company and the Company's failure to meet analysts' expectations. Additionally, the value of the Common Shares is subject to market value fluctuations based upon factors that influence the Company's activity and changes in interest and currency rates.

The market value of the Common Shares may also be affected by the Company's financial results and political, economic, financial, and other factors that can affect the capital markets generally, the stock exchanges on which the Common Shares are traded and the market segment of which the Company is a part.

*The Company May Be Impacted by Inflationary Pressures*

General inflationary pressures may affect labor and other costs, which could have a material adverse effect on the Company's financial condition, results of operations and the capital expenditures required to advance the Company's business plans. There can be no assurance that any governmental action taken to control inflationary or deflationary cycles will be effective or whether any governmental action may contribute to economic uncertainty. Governmental action to address inflation or deflation may also affect currency values. Accordingly, inflation and any governmental response thereto may have a material adverse effect on the Company's business, results of operations, cash flow, financial condition and the price of the Company's securities.

*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.

*Negative Operating Cash Flows*

Given that none of the Company's properties have yet to enter commercial production and generate cash flow, the Company had negative operating cash flow for its fiscal period ended December 31, 2024. To the extent that the Company has negative cash flow in future periods, the Company may need to deploy a portion of its cash reserves or a portion of the proceeds of any offering of Securities to fund such negative cash flow.

**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 and Skadden, Arps, Slate, Meagher & Flom LLP with respect to matters of U.S. 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.

**exemption from national instrument 44-101**

Pursuant to a decision of the Autorité des marchés financiers dated May 29, 2025, the Company was granted exemptive relief from the requirement that this Prospectus as well as the documents incorporated by reference herein and any Prospectus Supplement and the documents incorporated by reference therein to be filed in relation to an "at-the-market" distribution be publicly filed in both the French and English languages.

**PART II**

**INFORMATION NOT REQUIRED TO BE DELIVERED TO OFFEREES OR PURCHASERS**

**Indemnification of Directors and Officers**

Under the Canada Business Corporations Act (the "**CBCA**"), we may indemnify our current or former directors or officers or another individual who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of his or her association with us or another entity. The CBCA also provides that we may advance moneys to a director, officer or other individual for costs, charges and expenses reasonably incurred in connection with such a proceeding; provided that such individual shall repay the moneys if the individual does not fulfill the conditions described below.

However, indemnification is prohibited under the CBCA unless the individual:

&nbsp;&nbsp;&nbsp;&nbsp;· acted honestly and in good faith with a view to our best interests, or the best interests of the other
entity for which the individual acted as director or officer or in a similar capacity at our request; and

&nbsp;&nbsp;&nbsp;&nbsp;· in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty,
the individual had reasonable grounds for believing that his or her conduct was lawful.

Our by-laws require us to indemnify to the fullest extent permitted by the CBCA each of our current or former directors or officers and each individual who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including, without limitation, an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of his or her association with us or another entity.

Our by-laws authorize us to purchase and maintain insurance for the benefit of each of our current or former directors or officers and each person who acts or acted at our request as a director or officer, or an individual acting in a similar capacity, of another entity provided the individual acted in that capacity at our request.

**Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.**

**PART III**

**UNDERTAKING AND CONSENT TO SERVICE OF PROCESS**

**Item 1.** **Undertaking.**

The Registrant undertakes to make available, in person or by telephone, representatives to respond to inquiries made by the Commission staff, and to furnish promptly, when requested to do so by the Commission staff, information relating to the securities registered pursuant to Form F-10 or to transactions in said securities.

**Item 2.** **Consent to Service of Process.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Concurrently with the filing of this Registration Statement on Form F-10, the Registrant is filing with the Commission a written irrevocable consent and power of attorney on Form F-X.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Any change to the name or address of the Registrant's agent for service shall be communicated promptly to the Commission by amendment to Form F-X referencing the file number of this Registration Statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <sup>1</sup> There are being registered under this Registration Statement such indeterminate number of common shares, preferred shares, debt securities, subscription receipts, warrants, and units of Standard Lithium Ltd. (the "Registrant"), and a combination of such securities, separately or as units, as may be sold by the Registrant from time to time, which collectively, shall have an aggregate initial offering price not to exceed $1,000,000,000 (or its equivalent in any other currency used to denominate the securities). The maximum aggregate offering price is estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(o) under the U.S. Securities Act of 1933, as amended (the "Securities Act"). Pursuant to Rule 416 under the Securities Act, the securities being registered hereunder include such indeterminate number of common shares, preferred shares, debt securities, subscription receipts, warrants, and units as may be issuable with respect to the securities being registered hereunder as a result of stock splits, stock dividends, or similar transactions. The proposed maximum initial offering price per security will be determined, from time to time, by the Registrant in connection with the sale of the securities under this Registration Statement. The Registrant previously paid $27,275 in registration fees with respect to the Registration Statement on Form F-10 (File No. 333-259442) filed on September 10, 2021 (the "2021 Registration Statement"), pertaining to the registration of $250,000,000 of securities of the Registrant, of which $27,275 remained unutilized and was used to offset the total filing fee required of $27,550 (the Registrant transferred funds of $275 and used available offset for the remainder of the fee) with respect to the Registration Statement on Form F-10 (File No. 333-273462) filed on July 27, 2023 (the "2023 Registration Statement"), pertaining to the registration of $250,000,000 of securities of the Registrant, of which $22,040.26 remains unutilized and therefore, available for future registration fees pursuant to Rule 457(p) under the Securities Act. As the total filing fee required for this Registration Statement is $153,100, taking into consideration the available offset of $22,040.26 from the 2023 Registration Statement, the Registrant has accordingly transmitted $131,059.74 otherwise due for this Registration Statement.

The Registrant previously paid $27,550 in registration fees (the Registrant transferred funds of $275 and used available offset for the remainder of the fee) with respect to the 2023 Registration Statement, of which $22,040.26 remains unutilized ($27,275 of which was originally paid as part of the payment of the 2021 Registration Statement filing fees) and therefore, available for future registration fees pursuant to Rule 457(p) under the Securities Act. The fee payment made with the 2021 Registration Statement was $27,275 and the contemporaneous fee payment made with the 2023 Registration Statement was $275.
