ITEM 4. INFORMATION ON THE COMPANY

A. History and Development of the Company

Overview

The Company was incorporated under the BCBCA on November 27, 2007 under the name "Western Lithium Canada Corporation" and changed its name to "Western Lithium USA Corporation" on May 31, 2010. The Company amended its Articles in 2013 to add advance notice requirements for the election of directors, and in 2015 to give the Board the authority by resolution to alter the Company's authorized share capital and to make 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 consolidated its outstanding Shares on a 5:1 basis.

On January 25, 2022, the Company acquired all of the issued and outstanding securities of Millennial Lithium by way of a plan of arrangement (the "Millennial Arrangement"), at which point Millennial Lithium became a wholly owned subsidiary of the Company.

On April 20, 2023, the Company acquired all the common shares of Arena Minerals (the "Arena Shares"), which it did not already own, by way of a plan of arrangement, at which point Arena Minerals became a wholly owned subsidiary of the Company.

On October 3, 2023, the Company completed the Separation Transaction pursuant to which the Company separated its previously-held North American business unit, comprising the Thacker Pass project, as well as investments in Green Technology Metals Ltd. and Ascend Elements, Inc., into an independent public company named "Lithium Americas Corp.", which is listed on the TSX and NYSE. The Company retained its Argentine business unit, consisting of a 44.8% interest in Cauchari-Olaroz, the majority-owned Pastos Grandes Project and a 65% interest in the Sal de la Puna project. The Company's Shares continued to trade on the TSX and the NYSE following the Separation Transaction.

In August 2024, Ganfeng acquired $70 million in newly issued shares of PGCo, the Company's wholly-owned Argentinian subsidiary holding the Pastos Grandes Project, representing a 14.9% interest in PGCo and Pastos Grandes. The Company retained control of PGCo following this transaction. Proceeds from this transaction were allocated to the advancement of the Company's lithium projects in Argentina, including the reduction of the short-term debt of the Cauchari-Olaroz tied to start-up and working capital. In connection with the Pastos Grandes Transaction, Lithium Argentina, certain of its subsidiaries (the "Lithium Argentina Parties") and Ganfeng and its subsidiary (the "Ganfeng Lithium Parties", and together with the Lithium Argentina Parties, the "Parties") entered into a shareholders' agreement (the "Shareholders' Agreement") that, among other terms, provides for limited rights and obligations as between the Parties, including the following: (i) from the closing date until December 31, 2024, a standstill on the sale of an interest in PGCo or the Pastos Grandes Project; (ii) through to December 31, 2025, enhanced consent rights in favour of the Ganfeng Lithium Parties in respect of operational matters, as well as a right of first refusal in favour of the Ganfeng Lithium Parties over a sale of an interest in PGCo at the same valuation as that applicable to the Pastos Grandes Transaction (with the Lithium Argentina Parties having a right of first refusal over a sale by the Ganfeng Lithium Parties of the 14.9% interest); (iii) through to December 31, 2025, a right in favour of the Ganfeng Lithium Parties to acquire an aggregate 50% interest in the Pastos Grandes Project upon a change of control of Lithium Argentina by subscribing for share capital of PGCo in consideration for an incremental cash subscription price of $330 million; (iv) until December 31, 2025, an obligation to obtain consent of the Parties for any offtake agreement in respect of the Pastos Grandes Project; and (v) from January 1, 2025 to September 30, 2025, an enhanced 'tag-along' right of the Ganfeng Lithium Parties to include its interest along with a sale by the Lithium Argentina Parties of their interest in PGCo, and to realize a portion of the consideration that would otherwise be payable to the Lithium Argentina Parties upon such sale in addition to the equivalent proportionate consideration payable for the interest of the Ganfeng Lithium Parties (after such period the "tag along right" will survive but will only include the proportionate consideration).

B. Business Overview

Overview

The Company is a Swiss-domiciled resource company focused on advancing significant lithium projects. The Company holds a 44.8% interest in Cauchari-Olaroz in Jujuy, Argentina; an 85.1% interest in the Pastos Grandes Project in Salta, Argentina (subject to the Pastos Grandes Transaction); and a 65% interest in the Sal de la Puna project in Salta, Argentina. Additionally, the Company owns the Salar de Antofalla ("Antofalla Project") in the Province of Catamarca, Argentina.

The Company is focused on the operations at Cauchari-Olaroz and advancing the development of additional lithium resources in the region.

For a more detailed discussion of the Company's business structure and Cauchari-Olaroz, see Note 7 of the Company's audited consolidated financial statements for the years ended December 31, 2024, 2023 and 2022 included in "Item 18 - Financial Statements" of this annual report.

Specialized Skills

All aspects of the Company's business require specialized skills and knowledge, including geology, drilling, mining, processing, logistical planning, the implementation of exploration programs, and expertise in regulatory, finance and accounting matters. The Company relies on its management, employees and various consultants for this expertise.

Mineral Price and Economic Cycles

The principal end-use product for the Company's business is lithium-based chemicals, particularly battery-grade lithium carbonate. The markets for lithium-based products are affected by worldwide economic cycles and the volatility in supply and pricing that is commonly associated with commodity-based products. In the case of lithium-based products, demand is driven largely by the rate of adoption of lithium batteries, particularly those used in electric vehicles. Meanwhile, supply is driven by the production capacity of lithium producers and the ability of those operations to produce battery grade products, which are refined to a higher concentration of lithium with fewer impurities than non-battery grade lithium products.

Lithium prices have been volatile over the last several years. In 2022, lithium prices reached an all-time high due to, among other factors, supply constraints resulting from the increase in the adoption of electric vehicles and the corresponding demand for electric vehicle batteries and a disproportionate increase in supply as the timeline for new production to become available is, in most cases, measured over several years and is not responsive to short-term demand increases. The increase in demand, as well as efforts by governments to promote domestic industry through industrial policy and related efforts, has led to a significant increase in exploration and development stage lithium companies and projects being advanced throughout the world. More recently, however, lithium prices have decreased significantly due to, among other factors, rising supply, subdued demand and a lackluster electric vehicle market outside of China.

---

Intangibles

The Company does not hold any patents.

Sources and Availability of Raw Materials

All of the raw materials required for the Company's operations are available through standard supply and business contracting channels.

Government Regulations

The Company's exploration and future development activities are subject to various national, state, provincial and local laws and regulations in Argentina, the U.S., Switzerland, and Canada, which govern prospecting, development, mining, production, exports, taxes, labor standards, occupational health, waste disposal, protection of the environment, mine safety, hazardous substances and other matters.

Except as described in this annual report, the Company believes that it is in compliance, in all material respects, with applicable mining, health, safety and environmental statutes and regulations.

Competitive Conditions

Lithium currently has many end uses, including ceramics and glass, batteries, greases, air treatment and pharmaceuticals. However, it is the battery industry that is expected to predominantly drive future demand growth for lithium. This is expected to come from several areas: (i) the continued growth of small format batteries for cell phones, laptops, digital cameras and hand-held power tools, (ii) the transportation industry's electrification of automobiles, buses, delivery vehicles, motorcycles, bicycles and boats using lithium-ion battery technology, and (iii) large format batteries for utility grid-scale storage.

A small number of companies dominate the production of end-use lithium products such as lithium carbonate and lithium hydroxide. The bulk of production occurs in brine deposits in South America and spodumene hard-rock deposits in Australia as well as lepidolite production in China. There are a small number of additional companies who have initiated lithium-based production in recent years, as well as numerous additional companies pursuing the development of lithium mineral deposits throughout several jurisdictions.

Foreign Operations

Lithium operations and projects

Cauchari-Olaroz, the Pastos Grandes Project and the Sal de la Puna project are all located in Argentina. Cauchari-Olaroz is in operation while the projects under the Pastos Grandes basin segment are in the exploration and evaluation stage.

Offtake Agreement with Ganfeng and Bangchak

The Company and Ganfeng are entitled to a share of offtake from production at Cauchari-Olaroz. The Company is entitled to 49% of the offtake, which would amount to approximately 19,600 tonnes per annum ("tpa") of lithium carbonate assuming full capacity is achieved. The Company entered into an offtake agreement with each of Ganfeng and Bangchak on August 27, 2020 to sell a fixed amount of offtake production at market-based prices, with Ganfeng entitled to 80% of the first 12,250 tpa of lithium carbonate (9,800 tpa assuming full production capacity) and Bangchak entitled to up to 6,000 tpa of lithium carbonate (assuming full production capacity).

---

The balance of the Company's offtake entitlement, amounting to up to approximately 3,800 tpa of lithium carbonate is uncommitted, but for limited residual rights available to Bangchak to the extent production does not meet full capacity.

Purchases and sales of lithium carbonate

During the year ended December 31, 2024, the Company purchased its share of Exar's lithium carbonate shipped during the period with Ganfeng purchasing the remaining product shipped. The Company sold the purchased lithium carbonate to Ganfeng and Bangchak and acted in the capacity of agent in such sales transactions, as the Company's acquisition of title to lithium carbonate was simultaneous with the sale of lithium carbonate to Ganfeng and Bangchak and the Company was not directly exposed to inventory or price risk related to lithium carbonate.

Since there was no net amount of commission to the Company, there was no net impact on the Company's statement of comprehensive loss for the year ended December 31, 2024.

Exar and Exar Capital Agency Arrangement

In addition to project loans provided by Exar Capital, Exar Capital also provides support to Exar by purchasing, as agent, reagents and other materials on behalf of Exar from international suppliers.  Argentina does not allow access to the foreign exchange markets to permit prepayments by Argentine companies to international vendors, payments are only allowed after supplies arrive in Argentina. Accordingly, Exar Capital provides prepayments to suppliers and is then reimbursed by Exar once the supplies arrive in Argentina and Exar is able to make such payments in accordance with Argentinian foreign exchange regulations. 

Amended Shareholders Agreement

On October 25, 2018, the Company, 2265866 Ontario Inc. (now 2265866 Ontario Holdings B.V.), Ganfeng, Exar and Exar Capital entered into a shareholders' agreement to govern the Company's and Ganfeng's interests in Exar and Exar Capital and the funding and development of the Cauchari-Olaroz Operation. The shareholders' agreement was amended in 2019, and amended and restated in August 2020 for the closing of a transaction by which Ganfeng holds 51% and the Company 49% interest, respectively in Cauchari-Olaroz (the "Amended Shareholders Agreement").

The Amended Shareholders Agreement entered into on August 27, 2020 by the Company, 2265866 Ontario Inc. and Ganfeng generally provides for the following:

• the parties' respective rights regarding ownership interests in Exar and Exar Capital;
• requirements for funding and development of the Cauchari-Olaroz Operation, and rights and obligations of parties upon a failure to fund, including dilution of interest under certain circumstances;
• the formation of the Exar shareholder committee to direct the business and affairs of Exar, comprised of three representatives of Ganfeng and two representatives from the Company;
• the composition of the board of directors of Exar, being two representatives of Ganfeng and one representative of the Company;
• the composition of the board of directors of Exar Capital, being two representatives of Ganfeng and one representative of the Company;
• an 80% approval threshold for the Exar shareholder committee to approve a number of material corporate actions, thereby providing protection to the Company as a minority shareholder in Exar, such approvals of material corporate actions including but not limited to the following: (i) programs and budgets, and changes thereto or to contributions required to be made by the parties; (ii) issuances of securities or restructuring transactions involving Exar and Exar Capital; (iii) any sale, transfer or other disposition of an ownership interest in Exar or Exar Capital; (iv) changes to the composition of the Exar shareholder committee or the board of directors of Exar or Exar Capital; (v) material changes to terms contemplated by the agreement with JEMSE; (vi) any change to development activities that would materially delay the expected timeline for the Cauchari-Olaroz Operation to reach commercial production; and (vii) debt or guarantees above certain thresholds; and

Summary Overview of Mining

As used in this annual report, the terms "mineral resource," "measured mineral resource," "indicated mineral resource," "inferred mineral resource," "mineral reserve," "proven mineral reserve" and "probable mineral reserve" are defined and used in accordance with S-K 1300. All determinates of mineral resources and mineral reserves have been prepared by qualified persons. Under S-K 1300, mineral resources may not be classified as "mineral reserves" unless the determination has been made by a qualified person that the mineral resources can be the basis of an economically viable project. Mineral resources are not mineral reserves and do not meet the threshold for mineral reserve modifying factors, such as estimated economic viability, that would allow for conversion to mineral reserves. There is no certainty that any part of the mineral resources estimated will be converted into mineral reserves.

Except for that portion of mineral resources classified as mineral reserves, mineral resources have not demonstrated economic value. Inferred mineral resources are estimates based on limited geological evidence and sampling and have too high of a degree of uncertainty to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Estimates of inferred mineral resources may not be converted to a mineral reserve. It cannot be assumed that all or any part of an inferred mineral resource will be upgraded to a higher category. A significant amount of exploration must be completed to determine whether an inferred mineral resource may be upgraded to a higher category. Therefore, you are cautioned not to assume that all or any part of an inferred mineral resource can be the basis of an economically viable project, or that it will be upgraded to a higher category.

Property Description and Location

The Cauchari and Olaroz Salars are located in the Department of Susques in the Province of Jujuy in northwestern Argentina, approximately 250 km northwest of San Salvador de Jujuy, the provincial capital. The salars extend in a north-south direction from S23°18' to S24°05' and in an east-west direction from W66°34' to W66°51'. The average elevation of the salars is 3,940 metres. The midpoint between the Olaroz and Cauchari Salars is located along National Highway 52, 55 km west of the Town of Susques. The nearest port is Antofagasta (Chile), located 530 km west of the Project by road.

Ownership

The Company holds its interest in the Cauchari-Olaroz Operation through a 44.8% interest in Exar, with Ganfeng holding a 46.7% interest. Exar acquired mining and exploration permits applications through acquisition of such permits applications, direct request of permits from the applicable provincial mining authority and/ or through brines usufruct agreements in the Province of Jujuy, Argentina, covering a total of 60,712 ha in the Department of Susques, of which 28,717 ha can support the entire project. The claims are contiguous and cover most of the Cauchari Salar and the eastern portion of the Olaroz Salar. The annual aggregate payment (canon rent) required by Exar to maintain the claims is US$268,346. Under Exar's usufruct agreement with Borax Argentina S.A., Exar acquired Borax Argentina S.A.'s usufruct rights on properties in the area in exchange for an annual royalty of US$200,000 plus annual canon rent property payments to Jujuy Province. The area that contains the Mineral Resource and Mineral Reserve estimate is covered by mining concessions which grant the holder a perpetual mining right, subject to the payment of a fee and an agreed upon investment in accordance with the principal legislation that regulates the mining industry in Argentina, the Código de Minería.

On March 28, 2016, Exar entered into a purchase option agreement ("Option Agreement") with Grupo Minero Los Boros ("Los Boros") for the transfer of title to Exar for certain mining properties that comprised a portion of the Cauchari-Olaroz Operation. Under the terms of the Option Agreement, Exar paid US$100,000 upon signing, and obtained a right to exercise the purchase option at any time within 30 months for the total consideration of US$12M payable in sixty quarterly installments of US$200,000.

---

On November 12, 2018, Exar exercised the purchase option, acquired the properties by taking on the obligation to pay US$12,000,000 in 60 quarterly payments of US$200,000 and;, as a result, the following royaltyies became payable to Los Boros:

• US$300,000 was paid on November 27, 2018 because the commercial plant construction started (purchase option established payment within 10 days of the commercial plant construction start date);

• Quarterly installments of US$200,000; and

• 3% net profit interest for 40 years, to be paid annually in Argentine pesos, within 10 business days after calendar year end.

Exar can cancel the first 20 years of net profit interest in exchange for a one-time payment of US$7M and the second 20-year period for an additional US$7M.

On March 28, 2016, Sociedad Química y Minera de Chile S.A. ("SQM") and Exar executed a shareholders agreement that established the terms by which the parties planned to develop the Cauchari-Olaroz Operation.

On October 31, 2018, the Company closed a transaction with Ganfeng and SQM. Ganfeng agreed to purchase SQM's interest in the Cauchari-Olaroz Operation. The Company increased its interest in the Cauchari-Olaroz Operation from 50% to 62.5% with Ganfeng holding the remaining 37.5% interest and the parties entered into a shareholder agreement to govern their ownership and business operations of Exar. Ganfeng also provided the Company with a US$100 million unsecured, limited recourse subordinated loan facility as part of funding its 62.5% share of the project expenditures.

On August 19, 2019, the Company and Ganfeng completed a transaction whereby Ganfeng contributed US$160 million in Exar and increased its participating interest in Exar to 50%. At such transaction closing, the Company and GFL International Co., Limited ("GFL") each owned a 50% equity interest in Exar. The parties made certain consequential amendments to the shareholders' agreement governing their relationship to refer to the new equity ownership structure in Exar. The Company and GFL authorized Exar to undertake a feasibility study on a development plan to increase the initial production capacity from 25,000 tpa to 40,000 tpa of lithium carbonate, as well as certain permitting and development work in advance of a decision to increase the project production rate.

On August 27, 2020, the Company and Ganfeng closed a transaction whereby Ganfeng increased its participating interest in Exar to 51% by completion of a US$16 million capital contribution to Exar.As part of this transaction, Ganfeng provided $40 million to Exar Capital in non-interest-bearing loans, repayable in 2029 (with a right for an additional one-year extension) and contributed $600,000 to Exar Capital's equity to increase its interest from 37.5% to 51%. Proceeds of the loans from Ganfeng were used by Exar Capital to repay $40 million of loans owed to Lithium Argentina. At such transaction closing, GFL owned a 51% equity interest in Exar and Lithium Argentina a 49%. The parties made certain consequential amendments to the shareholders' agreement governing their relationship to refer to the new equity ownership structure in Exar.

On August 26, 2020, GFL, the Company and Exar entered into a Share Acquisition Option Execution Agreement with JEMSE, a Province of Jujuy state company, setting the guidelines of JEMSE acquisition of an 8.5% participating interest in Exar, proportionally diluting GFL and the Company participating interest accordingly. JEMSE acquired the Exar shares for a consideration of US$1 plus an amount equal to 8.5% of the capital contributions in Exar.  JEMSE will pay for the amount owed to the shareholders through the assignment of one-third of the dividends to be received by JEMSE from Exar after taxes. In accordance with the agreement, for future equity contributions GFL and the Company are obliged to loan to JEMSE 8.5% of the contributions necessary for JEMSE to avoid dilution, which loans also would be repayable from the same one-third dividends assignment, after taxes.

---

On October 3, 2023, the Company separated into two independent public companies, Lithium Americas (Argentina) Corp. and a new Lithium Americas Corp. The Company retained the Cauchari-Olaroz Operation as well as the Pastos Grandes Project and Sal de la Puna project in Argentina.

Current ownership of the Project is summarized in the following figure:

Ownership Structure

The surface rights of the area subject to exploitation are local aboriginal communities' land. Exar signed contracts with each aboriginal community to have the right to explore the property and for surface use, water use, transit, and building ponds and facilities. Most of these contracts also cover development and mining operations by Exar. For those contracts in which development and mining are not specifically addressed, Exar is working with the relevant community to extend the coverage of the contract to those areas. Exar has also agreed to support local communities through a number of infrastructure and education programs.

History

Mining activities on the western side of the Cauchari Salar by Rio Tinto and on the eastern side of the Olaroz Salar by Los Boros date back to the 1990s. 

2009 to 2010	Exar acquired mining and exploration permits across broad areas of the Cauchari and Olaroz Salars. Exploration programs focused on lithium and potassium were completed, which resulted in the preparation of a measured, indicated and inferred mineral resource report for potassium and lithium.
2012	An initial feasibility study was completed.

Geological Setting, Mineralization and Deposit Types

There are two dominant structural features in the region of the Cauchari and Olaroz Salars: north-south trending high-angle normal faults and northwest-southeast trending lineaments. The high-angle north-south trending faults form narrow and deep horst-and-graben basins which are accumulation sites for numerous salars, including Olaroz and Cauchari. Basement rock in this area is composed of Early Ordovician turbidites (shale and sandstone) intruded by Late Ordovician granitoids. It is exposed to the east, west and south of the two salars, and generally along the eastern boundary of the Puna Region.

The salars are in-filled with laminar deposits, dominated by the following five primary informal lithological units that have been identified in drill cores: (i) red silts with minor clay and sand; (ii) banded halite beds with clay, silt and minor sand; (iii) fine sands with minor silt and salt beds; (iv) massive halite and banded halite beds with minor sand; and (v) medium and fine sands.

---

Alluvial deposits intrude into these salar deposits to varying degrees, depending on location. The alluvium surfaces slope into the salar from outside the basin perimeter. Raised bedrock exposures occur outside the salar basin. The most extensive intrusion of alluvium into the basin is the Archibarca Fan, which partially separates the Olaroz and Cauchari Salars. Route 52 is constructed across this alluvial fan. In addition to this major fan, much of the perimeter zone of both salars exhibits encroachments of alluvial material associated with fans of varying sizes.

The brines from Cauchari are saturated in sodium chloride with total dissolved solids ("TDS") on the order of 27% (324 to 335 grams per litre) and an average density of about 1.215 grams per cubic centimetre. The other primary components of these brines include potassium, lithium, magnesium, calcium, sulphate, bicarbonate, and boron as borates and free boric acid. Since the brine is saturated in sodium chloride, halite is expected to precipitate during evaporation. In addition, the Cauchari brine is predicted to initially precipitate halite and ternadite as well as a wide range of secondary salts that could include: astrakanite, schoenite, leonite, kainite, carnalite, epsomite and bischofite.

The Cauchari and Olaroz Salars are classified as "Silver Peak, Nevada" type terrigenous salars. Silver Peak, Nevada in the United States was the first lithium-bearing brine deposit in the world to be exploited. These deposits are characterized by restricted basins within deep structural depressions in-filled with sediments differentiated as inter-bedded units of clays, salt (halite), sands and gravels. In the Cauchari and Olaroz Salars, a lithium-bearing aquifer has developed during arid climatic periods. On the surface, the salars are presently covered by carbonate, borax, sulphate, clay and sodium chloride facies. Cauchari and Olaroz have relatively high sulphate contents and therefore both salars can be further classified as "sulphate type brine deposits".

Exploration

The following exploration programs were conducted between 2009 and 2024 to evaluate the lithium development potential of the Cauchari-Olaroz Operation area:

• Surface Brine Program - 55 brine samples were collected from shallow pits throughout the salars to obtain a preliminary indication of lithium occurrence and distribution.
• Seismic Geophysical Program - Seismic surveying was conducted to support delineation of basin geometry, mapping of basin-fill sequences, and siting borehole locations.
• Gravity Survey - A limited gravity test survey was completed to evaluate the utility of this method for determining depths to basement rock.
• Time Domain Electromagnetic ("TEM") Survey - TEM surveying was conducted to attempt to define fresh water and brine interfaces within the salar.
• Air Lift Testing Program - Testing was conducted within individual boreholes as a preliminary step in estimating aquifer properties related to brine recovery.
• Vertical Electrical Sounding ("VES") Survey - A VES survey was conducted to attempt to identify fresh water and brine interfaces, and surrounding freshwater occurrences.
• Surface Water Sampling Program - A program was conducted to monitor the flow and chemistry of surface water entering the salars.
• Pumping Test Program 2011-2019 - Pumping wells were installed at eleven locations, to estimate aquifer parameters related to brine recovery. One of the locations was used to estimate the capacity of fresh water supply. Some tests were carried out using multiple wells on the same platform in order to estimate three-dimensional aquifer parameters.
• Boundary Investigation - A test pitting and borehole program was conducted to assess the configuration of the fresh water/brine interface at the salar surface and at depth, at selected locations on the salar perimeter.

---

Drilling

From September 2009 to August 2010, a total of 4,176 m of Reverse Circulation ("RC") Borehole drilling was conducted to develop vertical profiles of brine chemistry at depth in the salars and to provide geological and hydrogeological data. The program included installation of 24 boreholes and collection of 1,487 field brine samples (and additional Quality Control samples). The sampled brines have a relatively low magnesium-to-lithium ratio (lower than most sampling intervals), indicating that the brines would be amenable to a conventional lithium recovery process.

Diamond drilling at the Cauchari-Olaroz Operation was conducted between October 2009 and August 2010. This program was conducted to collect continuous cores for geotechnical testing and geological characterization. The program included 29 boreholes and collection of 127 field brine samples (and additional quality control samples).

A drilling and sampling program was conducted from July 2017 to June 2019. The program included a total of 49 boreholes and 9,703 meters of cores recovered. In 2019, 58 additional samples were sent for testing (this program also included a total of 1,006 samples sent to the laboratory for brine characterization, including quality assurance and quality control ("QA/QC") samples).

Information from the exploration drilling and pump tests was used to select the locations of the production wells that will be used to pump lithium brine to the evaporation ponds. Since 2011 a total of 10 production wells have been drilled on the Property.

The production well field uses three wells drilled in 2011. These wells had a smaller diameter of 8 inches. The wells drilled in 2018 and 2019 were drilled deeper and used a larger diameter based on the expected flow. The production wells were drilled with conventional rotary rigs and a surface casing at the top of the wells to ensure the stability of the well head over time. The design of the deeper wells used larger diameter casing in the upper 200/250 m, continuing with smaller diameter casing below.

Mineral Resource and Reserve Estimates

The Company has not previously disclosed mineral reserve or resource estimates in accordance with S-K 1300.  The following is a brief discussion of the material assumptions and criteria underlying the mineral resource and reserve estimates.  Please see Section 11 and 12 of the Cauchari TRS for more detail.

A Mineral Resource and Mineral Reserve estimate for the Cauchari-Olaroz Operation is summarized in the tables below.

Mineral Resources

The prior Mineral Resource estimate from 2019 was not prepared in accordance with S-K 1300. The Company has previously filed the NI 43-101 technical reports on the Cauchari-Olaroz Operation providing prior Mineral Resource estimates for lithium and the previous resource estimate was prepared in accordance with CIM standards under NI 43-101. The Mineral Resource estimate included in the Cauchari TRS complies with S-K 1300 and has an effective date of May 7, 2019.  Mr. Daniel S. Weber, P.G., RM-SME for Cauchari-Olaroz, and a qualified person under S-K 1300, reviewed and confirmed that the Mineral Resource and Mineral Reserve estimates, along with the material assumptions related to them, as presented in the Cauchari TRS, remained current as of the effective report date of December 31, 2024.

Since the 2019 mineral estimates, the results of deeper drilling and sampling have allowed for partial conversion of the Inferred Resource aquifer volume in the updated HSU model to Measured and Indicated Resource aquifer volume of the deeper HSUs. This conversion of aquifer volume to more confident Mineral Resource estimate categories provided support for simulated wells in the Mineral Reserve estimate numerical model to be completed in the deeper and more permeable lower sand and basal sand HSUs in the southeast part of the model domain. This resulted in the Mineral Resource estimate included in the Cauchari TRS with an effective date of May 7, 2019. 

---

The Mineral Resource estimate below is based on the total amount of lithium in brine that is theoretically drainable from the bulk aquifer volume. The Mineral Resource estimate is computed as the overall product of the Mineral Resource evaluation area and aquifer thickness resulting in an aquifer volume, lithium concentration dissolved in the brine and specific yield of the Mineral Resource aquifer volume. This framework is based on an expanded and updated hydro stratigraphic model incorporating bulk aquifer volume lithologies and specific yield estimates for block modeling of the Mineral Resource estimate. Radial basis function was performed as the main lithium distribution methodology using variogram modeling techniques; the interpolation method was verified with ordinary kriging. The Mineral Resource block model was validated by means of visual inspection, checks of composite versus model statistics and swath plots. No areas of significant bias were noted. The S-K 1300 regulations were followed for the Mineral Resource Estimate.

(3) The Mineral Resource estimate is reported in-situ and exclusive of Mineral Reserves, where the lithium mass is representative of what remains in the reservoir after the LOM. To calculate Mineral Resources exclusive of Mineral Reserves, a direct correlation was assumed between Proven Reserves and Measured Resources, and similarly, between Probable Reserves and Indicated Resources. Proven Mineral Reserves (from the point of reference of brine pumped from the wellfield to the evaporation ponds) were subtracted. The average grade for Measured and Indicated Resources exclusive of Mineral Reserves was back-calculated based on the remaining brine volume and lithium mass.

(4) LCE is calculated using mass of LCE = 5.322785 multiplied by the mass of Lithium reported in Table 11.5.

(5) The Mineral Resource Estimate is not a Mineral Reserve Estimate and does not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted to Mineral Reserves. Inferred Resources have great uncertainty as to their existence and whether they can be mined legally or economically.

(6) Calculated brine volumes only include Measured, Indicated, and Inferred Mineral Resource volumes above a lithium concentration cut-off grade of 300 mg/L.

(7) Comparisons of values may not add due to rounding of numbers and the differences caused by use of averaging methods.

(8) Processing efficiency is assumed to be 53.7%

(9) The commodity price of $20,000/tn for lithium carbonate (2025) for the life of the project was used to assess the economic viability for the mineral estimates.

The following material assumptions and parameters were used for the mineral resource estimates. Also, this information is available in Cauchari TRS Section 11:

Mineral Reserve

The prior Mineral Reserve estimate for lithium, which was not prepared in accordance with S-K 1300, incorporates the updated Mineral Resource estimate and additional drilling and testing through an effective date of May 7, 2019. The Company has previously filed the NI 43-101 technical reports on the Cauchari-Olaroz Operation providing prior Mineral Resource estimates for lithium and the previous resource estimate was prepared in accordance with CIM standards under NI 43-101. To obtain the updated Mineral Reserve estimate, the previous hydro stratigraphic and numerical models and the expanded database were analyzed and updated by LRE Water. Once formulated and calibrated, the updated numerical model used a simulated production wellfield to project extraction from the brine aquifer and verify the feasibility of producing sufficient brine for processing a minimum target of 40,000 tpa of lithium carbonate for a 40-year operational period. After verifying the capability of the simulated wellfield to produce sufficient brine for the minimum 40,000 tpa lithium carbonate process target, the model was then used to predict a maximum production rate for assessment of total Mineral Reserve estimate for a 40-year production and process period of lithium carbonate.

---

The Proven and Probable Mineral Reserve estimate is summarized without factoring estimated process efficiency (pre-processing). The Measured and Indicated Mineral Resources correspond to the total amount of lithium enriched brine estimated to be available within the aquifer while the Proven and Probable Mineral Reserves represent a portion of the Mineral Resource estimate that can be extracted under the proposed pumping schedule and wellfield configuration. Therefore, the Mineral Reserve estimation is not "in addition" to the Mineral Resource estimate, and instead, it simply represents a portion of the total Mineral Resource that is extracted during the life of mine plan. A cut-off value was not employed in the Mineral Reserve estimate because the average calculated lithium concentration after 40 years of simulated mine life was significantly above the processing constraint.

Summary of Estimated Proven and Probable Mineral Reserves (Without Processing Efficiency)
Reserve Classification	Production Period (Years)	Brine Pumped (m3)	Average Lithium Concentration (mg/L)	Lithium Metal (tonnes)	LCE (tonnes)	LCE - Lithium Argentina's 44.8% Portion (tonnes)
Proven	0 through 5	156,875,201	616	96,650	514,450	230,474
Probable	6 to 40	967,767,934	606	586,270	3,120,590	1,398,024

Notes:

(1) The Mineral Reserve Estimate has an effective date of May 7, 2019. The Qualified Person for these Mineral Resources and Mineral Reserves estimates for Cauchari-Olaroz, Mr. Daniel S. Weber, P.G., RM-SME, reviewed and confirmed that the Mineral Reserves estimates, along with the material assumptions related to them, as presented in the Cauchari TRS, remained accurate as of the effective report date of December 31, 2024.

(2) LCE is calculated using mass of LCE = 5.322785 multiplied by the mass of Lithium Metal.

(3) The conversion to LCE is direct and does not account for estimated processing efficiency.

(4) The values in the columns for "Lithium Metal" and "LCE" above are expressed as total contained metals.

(5) The production period is inclusive of the start of the model simulation (Year 0).

(6) The average lithium concentration is weighted by per well simulated extraction rates.

(7) Tonnage is rounded to the nearest 10.

(8) Comparisons of values may not be equivalent due to rounding of numbers and the differences caused by use of averaging methods.

(9) Processing efficiency is assumed to be 53.7%.

(10) The point of reference is brine pumped from the wellfield to the evaporation ponds.

(11) The commodity price of $20,000/tn for lithium carbonate (2025) for the life of the project was used to assess the economic viability for the mineral estimates.

The QPs believe the Mineral Reserve estimate has been conservatively modeled and represents a Proven Mineral Reserve for year one through five of full-scale extraction wellfield pumping and Probable Reserve for years six through 40 of extraction wellfield pumping. The division between Proven and Probable Mineral Reserves is based on: 1) sufficiently short duration of wellfield extraction to allow a higher degree of predictive confidence yet long enough to enable significant production; and 2) a duration long enough to enable accumulation of a strong data record to allow subsequent conversion of Probable to Proven Mineral Reserves.

During 2023 and 2024, the first years of operation, 39 wells were operative to support LCE production. During 2023, 496 l/s of brine were delivered to the wellfield and in 2024 an average of 706 l/s of brine were pumped.

Considering a conservative processing efficiency of 53.7%, the predicted results for the 40-year production period are as follows.

• Average production rate of 47,700 tpa LCE for the 40-year pumping period.

• Average production rate of 48,700 tpa LCE following the completion of the 40-year pumping period.

• Average lithium concentration of 609 mg/L for the 40-year pumping period, considering an average lithium grade assumption is 638 mg/l during the first years of operation.

• Minimum lithium concentration of 598 mg/L near the end of the pumping period in year 40.

Overview of Mining and Production Operations

In 2019, Exar developed a process for converting brine to high- purity lithium carbonate. The proposed process follows industry standards: pumping brine from the salar, concentrating the brine through evaporation ponds, and taking the brine concentrate through a hydrometallurgical facility to produce high-grade lithium carbonate. While the 2012 process model employed proprietary, state-of-the-art physiochemical estimation methods and process simulation techniques for electrolyte phase equilibrium, the 2019 model uses a process model that has been further refined using the results of lab scale and pilot scale testing from Exar, Ganfeng, and equipment suppliers, the results of which were implemented in the detail engineering of the facilities. The basis of the process methods has been tested and supported by laboratory test work, pilot testing facilities, and equipment vendor testing and design to support equipment guarantees.

The process route simulated for the production of lithium carbonate from Cauchari brines resembles the flowsheet presented in shown in the "Overall Process Block Diagram" below.

Primary process inputs include evaporated brine, water, lime, soda ash, HCl, NaOH, and natural gas. The evaporation ponds produce salt tailings composed of Na, Mg, Ca, K, and borate salts. The brine concentrate from the terminal evaporation pond is further processed, through a series of polishing and impurity removal steps. Soda ash is then added with the purified brine concentrate to produce lithium carbonate that is dried, micronized, and packaged for shipping.

Mineral Extraction

It is contemplated that brine will be extracted from 56 production wells situated across the Mineral Reserve area. The wells comprising the brine extraction wellfield are spatially distributed in the Mineral Reserve evaluation area of the Cauchari-Olaroz Operation to optimize well performance and capture of brine enriched in lithium. Production was initiated in year one of the pumping schedule representing 23 Stage 1 wells. In years two through 40, 33 wells are added to the pumping schedule for the duration of the life of mine plan. During the "Stage 2" pumping period, the average nominal pumping rate per well is 16 L/s capacity, providing approximately 903 L/s of lithium enriched brine from the aquifer to the evaporation ponds.

The pond system consists of 28 evaporation ponds segregated into the following types: (i) 16 pre-concentration ponds; (ii) six ponds used as halite ponds; (iii) two ponds used as sylvinite ponds; (iv) two ponds used for control; and (v) two ponds used for lithium ponds.

An average evaporation rate of 6.05 mm per day (2,157 mm/year) was used as a criterion to design the pond system. This rate corresponds to measured evaporation rates observed at the site where the ponds will be located. Assuming the above-mentioned evaporation rate, the total evaporation area required for the production of 40,000 tpa of lithium carbonate is 1,200 hectares when including consideration for harvesting of salt deposited in the ponds. The ponds are lined with a multi-layer liner consisting of polymer-based material and engineered granular bedding. The ponds configuration includes provision for uninterrupted production during salt harvesting and maintenance work. Brine will be transferred between the successive evaporation ponds using self-priming pumps.

---

Along with lithium, the pumped brine is projected to contain significant quantities of potassium magnesium, sulfate and boron. These constituents will be removed from the brine during the extraction and evaporation process to enable effective retrieval of lithium.

Processing and Recovery Operations

Exar and its consultants subjected the brine chemistry of the deposits to a process simulation, using physicochemical properties estimation methods and process simulation techniques for phase equilibrium of solids in electrolytes (brine), specially prepared for this project. This work has been supported by the results of laboratory evaporation test work and test work at both the pilot plant and the pilot ponds.

The process route simulated for the production of lithium carbonate from Cauchari brines is outlined in a flowsheet in the Cauchari TRS. Primary process inputs include evaporated brine, water, lime, soda ash, hydrochloride, sodium hydroxide, steam, and natural gas. The evaporation ponds produce salt tailings composed of sodium, magnesium, potassium and borate salts. The brine concentrate from the terminal evaporation pond is further processed, through a series of polishing and impurity removal steps. Soda ash is then added with the purified brine concentrate to produce a lithium carbonate precipitate, that is dried, compacted/micronized and packaged for shipping.

The Company estimates that the required brine production rate should be achieved with 46 brine wells. An additional seven wells are planned for backup purposes. It is estimated that an additional one well per year of operation will be drilled throughout the 40-year operation to maintain brine productivity. 

At start-up, 40 production wells were delivered for brine production, with an estimated average nominal capacity of 16.3 L/s, that will provide up to 652 L/s of brine to the ponds. Additionally, 13 wells will be completed during the first five years to have the operation fed by 53 wells. This flow rate assumes a yield of 53.7% on the whole lithium carbonate process

The wells will be screened across the most productive lithium and sealed against freshwater aquifers.

Site Infrastructure and Support Systems

Construction of the project commenced in 2018. Natural gas is obtained from the Rosario gas compression station, which is on the Gas Atacama pipeline, 52 km north of the project site. This pipeline is be capable of supplying natural gas at capacities that are sufficient for a 40,000 tpa lithium carbonate facility.

Electricity is provided by a 33 kV transmission line that interconnects with an existing 345 kV transmission line located approximately 60 km south of the Cauchari-Olaroz Operation. The interconnection involves a sub-station with a voltage transformer (345/138 kV) and associated switchgear. Another substation at the Cauchari-Olaroz Operation site consists of A stepdown 33/13.2 kV substation at the Project site, consist of two voltage transformers (33/13,2 kV, 15-20 MVA), one (1) 33 kV electrical room and one (1) 13.2 kV electrical room with suitable switchgears and auxiliary equipment for the 13.2 kV local distribution system.

The 13.2 kV local electrical distribution system provides power to the plant, camp, intermediate brine accumulation and homogenizing pools/lime pumps, wells and evaporation ponds. In general, all distribution is aerial unless there are major restrictions, in which case underground distribution is adopted. The estimated load for the Cauchari-Olaroz Operation is approximately 123,461 MWh/y or 16.4 MW/h, which includes a design safety factor of 1.2. The power line has sufficient capacity for this load plus the existing users A stand-by dual diesel/gas generating station, located close to the main substation, can power selected equipment during grid outages.

---

Water for industrial use is supplied by groundwater wells adjacent to the salar and a water pipeline from the north. The infrastructure for water handling includes wells, low-voltage transmission lines to power the wells, pipelines, storage tanks and reverse osmosis plants. Water is required by the process and both camps.

The construction and permanent camps are located approximately 8,000 m south of National Highway 52. The permanent camp is a full habitation and administrative complex to support all workforce activities, with a capacity for 634 people, and includes office buildings, bedrooms, dining facilities, medical room, and recreation areas, consisting of a gym, an indoor sports center, a recreation room and an outdoor soccer field. The permanent camp covers a footprint of 8,500 m² of buildings and 35,700 m² of external facilities. In the construction camp there are eight housing modules with a total capacity of 392 people, of which only three modules are currently in use. In addition, this camp includes the pilot plant facilities, water treatment plants, and contractor workshops.

Additional buildings in permanent camp include:  lithium carbonate plant; spare parts and consumables warehouse building; soda ash storage building; final product - lithium carbonate - storage building; chemical laboratory; maintenance shop; and water treatment plants.

The figure below shows the location of the main facilities that are part of the Cauchari-Olaroz Operation, including:

• Well field;

• Evaporation ponds;

• Lithium carbonate plant;

• Salt and process residues disposal; and

• Camp.

Well Production Equipment Selection. Screened wells target the largest lithium brine aquifers. Submersible electric pumps are used for brine pumping. These pumps send the brine to evaporation ponds through a network of pipelines and mixing pools.

Evaporation Ponds. An average water evaporation rate of 6.26 mm per day was used as criterion to design the pond system. This rate corresponds to measured evaporation rates observed at the site where the ponds are located.

Assuming the above-mentioned evaporation rate, the total evaporation area required for the production of 40,000 tpa of lithium carbonate is 1,200 ha when including consideration for harvesting of salt deposited in the ponds. The ponds are lined with multi-layer liner consisting of a polymer-based material and engineered granular bedding. The ponds configuration includes provision for uninterrupted production during salt harvesting and maintenance work.

Brine is transferred between the successive evaporation ponds using self-priming pumps.

---

Salt Harvest Equipment. In order to recover pond volume taken up by precipitated salt and recover lithium values entrapped with the brine; salt is harvested. Harvesting began after the third year of steady pond operation.

The harvesting operation consists of draining the free brine from the pond, scraping the salt to a minimum depth, and making drainage trenches before removing salt.

Exar is allocating land to host waste salt deposits, which are expected to reach up to 15 m in height and cover 740 hectares over a 40-year mine life. These deposits are inert, with sodium chloride and sulphate making up approximately 87% of the material, and do not introduce foreign compounds to the environment. Cauchari-Olaroz has established an evaporation pond for its industrial liquid waste, and a 50 hectare area is allocated for this purpose.

Mining and Environmental Permits

Exar has developed a plan that promotes social and economic development within a sustainable framework. Exar began work on the Communities Relations Program with the Department of Susques in the Province of Jujuy in 2009. This plan was created to integrate local communities into the Cauchari-Olaroz Operation by implementing programs aimed at generating positive impacts on these communities.

Permitting processes for the Cauchari-Olaroz Operation are governed by Argentina's national and provincial laws, with oversight from the Jujuy provincial government. Recent updates under Decree No. 7,751- DEyP-2023 have modernized permitting standards, including enhanced consultation protocols and mandatory financial assurances for closure.  The Cauchari-Olaroz Operation's permits for exploration and exploitation activities are in full compliance, with biannual updates submitted as required.

SUMMARY OF KEY PERMITTING MILESTONES
Permit Type	Date Approved	Key Updates
Exploration	August 2009 (initial)	Regular biannual updates reflecting new activities.
Exploitation	November 2012 (initial)	Expand production capacity and operational adjustments.
Water Use	December 2020 (160 L/s)	Permanent concession granted; additional permits pending.

An additional water concession permit for a further 160 L/s from the south of the basin, for the exploitation phase for a 40 year terms, has been submitted and is currently under evaluation.

The Cauchari-Olaroz Operation has also obtained approvals for the provision of electricity to the Exar plant and for internal consumption by Resolution No. 406/2019 SCA, for natural gas by Resolution No. 350/2019 SCA and addendum approved by Resolution No. 215/2020 SCA, for water treatment plant at the construction camp by Resolution No. 327/2018 SCA, for water treatment plant at the operations camp by Resolution No. 226/2020 SCA and for aqueduct with environmental feasibility by Resolution No. 310/2020 SCA.

Operating Costs

The Cauchari TRS presents a cost estimate (±15% expected accuracy) for the Cauchari-Olaroz Operation of US$6,543 per tonne of lithium carbonate, based on 40,000 tpa lithium carbonate production. This estimate is based upon vendor purchase orders for main costs such as reagents, fuel (diesel and natural gas), electricity, maintenance, halite harvesting, transport, and catering and camp services. Reagents consumption rates were determined by pilot plant and laboratory work, as well as detailed process mass and energy balances. Energy consumption was determined on the basis of the specific equipment considered in each sector of the facilities and their utilization rate. Labour requirements are based on Exar's actual manpower used during the ramp up period.

---

Labour costs have been estimated using the results of a salary survey, carried out on behalf of Exar in Argentina, on mining companies with similar conditions and actual salaries paid by Exar. Consumables costs were estimated on the basis of existing supplier contracts and forecasted changes in future prices.

The exchange rate between the Argentine peso and the U.S. dollar has been assumed as AR$970/US$1. No provision for currency escalation has been included.

Project Economics

An economic analysis was outlined in the Cauchari TRS considering that construction for the project commenced in 2018 and significant funds were spent since then. All capital expenditures prior to December 31, 2024 are considered sunk and are not included in the capital expenses in the economic model. Only capital expenditures from December 31, 2024, onwards are included. Investment decisions are made on a forward-looking basis. The purpose of the economic model is to assess whether future capital expenses and operations, with updated product price, production costs, and other assumptions, will bring a positive economic result. Positive economic results include future cash flows, generated from sales of the finished product, less related cost of sales and other expenses, excluding capital expenditures prior to December 31, 2024. The economic assessment ignores sunk costs in the determination of cash flows and economic indicators. However, these costs are considered as opening balances for the purpose of determining tax assets and liabilities.  With the exclusion of the historic capital spent from the discounted cashflow, the presentation of an IRR value is not considered to be applicable.

Information contained in the Cauchari TRS, including (but not limited to) the project economics for the Cauchari-Olaroz Operation presented below (including, for greater certainty, revenue, net present value, cash flow and earnings) are presented as of the effective date of the Cauchari TRS based on criteria, assumptions, estimates and other information available at the time and therefore may not reflect actual results and outcomes, updated project economics, capital costs and/or operating costs for the project. As a result, actual results may differ from those presented. See "Item 3.D. - Risk Factors".

The following criteria have been used to develop the economic model:

• Engineering and construction period is estimated at four years, while the life of mine is estimated to be 40 years;
• Pricing was obtained from a market study (see Section 16 of the Cauchari TRS). Deductions to the price related to the removal of trace levels of impurities to achieve battery quality lithium carbonate are described as tolling costs in the economic model and deducted from revenue;
• Production based on design capacity of 40,000 tpa of lithium carbonate;
• Valuation date of December 31, 2024;
• For project evaluation purposes, it has been assumed that 100% of capital expenditures, including pre-production expenses and working capital are financed with owners' equity;
• Brine composition may be suitable for extraction and commercial production of other salts or other chemical compounds such as Boric Acid (H₃BO₃), potassium, etc. These options were not included in the Cauchari TRS;
• The economic evaluation was carried out on a constant money basis so there is no provision for escalation or inflation on costs or revenue;
• All values are expressed in current US dollars; the exchange rate between the Argentine peso and the US dollar as at October 31, 2024 was AR$970/US$. Argentine peso denominated costs follow the exchange rate as a result of inflation, and the impact of the exchange rate fluctuation on CAPEX and OPEX has been incorporated; no provision for currency escalation has been included; and

---

• The base-case assessment was carried out on a 100%-equity basis. Apart from the base case discount rate of 8.0%, two (2) variants of 6.0% and 10.0% were used to determine the NPV of the Cauchari-Olaroz Operation. These discount rates represent possible costs of equity capital.

In addition to capital and operating cost expenses as set forth in the Cauchari TRS, project economics are based on additional expenses and cash flow items including: Argentinean transaction tax, Jujuy provincial and private royalties, licenses and permits, export refunds, easement rights, equipment depreciation, sustaining capital, exploration expenses, amortization and remediation allowances.

Production Schedule

The Cauchari TRS production model outlines lithium carbonate production totaling 1,452,000 tonnes over period from 2025 to 2060. Overall efficiency of brine processing to produce lithium carbonate is reported to be 53.7%. To account for processing efficiency, the net amount of lithium carbonate produced was computed by multiplying the LCE extracted from the well field by 53.7%. The resulting values from each production well were then summed for each production year to determine the predicted annual lithium carbonate production. During the entire 40-year simulated production period the cumulative lithium carbonate, after accounting for processing efficiency, is projected to average 38,667 tonnes from the years 2025-2023 and 40,000 tonnes for years 2031-2060.

In the Cauchari TRS production model, it is assumed that in for years 2025-2030 average annual revenue will be US$709,000,000 and for years 2031-2060 average annual revenue will be US$780,000,000. The production model assumes a lithium carbonate price of US$20,757/tonne. The commodity price of $20,000/tn for lithium carbonate (2025) was used to assess the economic viability for the mineral estimates but was not used for cut-off purposes.

NPV

Set forth below is a table that illustrates the sensitivity of the project economics based on three lithium carbonate pricing scenarios and discount rates. The below is presented on a 100% project equity basis and measured from the end of the capital investment period. The Company owns 44.8% of the Cauchari-Olaroz Operation as of the date of this annual report.

The Company does not have historical non-GAAP financial measures nor historical comparable measures under IFRS, and therefore the foregoing prospective non-GAAP financial measure may not be reconciled to the nearest comparable measure under IFRS. Because the Company has provided these measures on a forward-looking basis, it is unable to present a quantitative reconciliation to the most directly comparable financial measure calculated and presented in accordance with IFRS without unreasonable efforts. This is due to the inherent difficulty of forecasting the timing or amount of various reconciling items that would impact the most directly comparable forward-looking IFRS measure that have not yet occurred, are outside of the Company's control and/or cannot be reasonably predicted.

Discounted Cash Flow

The figure below summarizes cash flows on a yearly basis for the period for the medium price scenario.

Mineral Reserve and Resource Estimate Comparison Between December 31, 2023 and 2024

For the year ended December 31, 2023, the Company was not subject to S-K 1300, and reported its mineral reserve and resources in accordance with NI 43-101.  For ease of comparison, the estimates for the project are shown on a 100% basis.  The Company's attributable interest is 44.8% of the tonnage stated in the tables.

Mineral Resources

The table below sets forth the comparison of the Mineral Resources as set forth in the Company's annual report on Form 40-F for the year ended December 31, 2023, and as set forth in the Company's annual report on Form 20-F for the year ended December 31, 2024. The decreases in the mineral resources are primarily due to the fact that under S-K 1300, mineral resources are estimated exclusive of mineral reserves.

Pastos Grandes Project

Project Overview

The Pastos Grandes Project was acquired by the Company in connection with the acquisition of 100% of the issued and outstanding shares of Millennial Lithium on January 25, 2022. The Pastos Grandes Project is an exploration stage lithium brine mineral project located in the central portion of the Salar de Pastos Grandes basin in the Salta Province, Argentina.

The site of the Pastos Grandes Project is near Highway 129 which connects 40 km north with Highway 51. Highway 51 traverses from Salta to the international border with Chile at the Sico Pass and connects further west to the major mining center of Calama, as well as the ports of Antofagasta and Mejillones in northern Chile. Both ports are major transportation hubs for the importation of mining equipment and the exportation of mineral commodities.

The total book value of the Pastos Grandes Project is $351 million as of December 31, 2024.

The Company retained Atacama Water to prepare "NI 43-101 Technical Report: Lithium Resource Update Pastos Grandes Project, Salta Province, Argentina" with an effective date of April 30, 2023, with the objective of updating the resource estimate for lithium contained in brine for the Company's properties in the Pastos Grandes basin excluding the Sal de la Puna properties based on the consolidation and integration of available information. The resource estimation for the Pastos Grandes Project was developed using SgeMS and the geological model as a reliable representation of the local lithology. The principal author was closely involved with the block model development; all results have been reviewed and checked at various stages and are believed to be valid and appropriate for these resource estimates. CIM definitions were followed for Mineral Resources, and the works were certified by the "qualified person" Frederik Reidel, CPG. The effective date of the Mineral Resources estimate is December 31, 2024.

Recent Developments

In August 2024, the Company completed the transaction with a subsidiary of Ganfeng whereby Ganfeng Lithium acquired $70 million in newly issued shares of PGCo, the Company's indirect wholly-owned Argentinian subsidiary holding the Pastos Grandes Project, which represents an approximate 14.89% interest in PGCo and the project. Proceeds of the subscription were allocated to the advancement of the Company's lithium projects in Argentina. In connection with the subscription, the Company and Ganfeng executed a shareholders agreement that, among other terms, provides for limited term rights and obligations as between the parties, including the following: (i) from the closing date until December 31, 2024, a standstill on the sale of an interest in the Pastos Grandes Project; (ii) during the course of 2025, enhanced consent rights in favour of Ganfeng in respect of operational matters, as well as a right of first refusal in favour of Ganfeng over a sale of an interest in PGCo at the same valuation as that applicable to the Pastos Grandes Transaction (with the Company having a right of first refusal over a sale by Ganfeng of its interest); (iii) from closing through to December 31, 2025, a right in favour of Ganfeng to acquire an aggregate 50% interest in the Pastos Grandes Project upon a change of control of the Company by subscribing for share capital of PGCo in consideration for an incremental cash subscription price of US$330 million; and (v) from January 1, 2025 to September 30, 2025, an enhanced 'tag-along' right of Ganfeng to include its interest along with a sale by the Company of its interest in PGCo , and to realize a portion of the consideration that would otherwise be payable to the Company upon such sale in addition to the equivalent proportionate consideration payable for the interest of Ganfeng (after such period the "tag along right" will survive but will only include the proportionate consideration).

Ganfeng and Lithium Argentina had have begun advancing thepreparation of a regional development plan for the Pastos Grandes basin, which includes the Company's Pastos Grandes Project and the Sal de la Puna project, and Ganfeng's adjacent Pozuelos project. The development plan will include significant technical collaboration to explore the best technologies, including direct lithium extraction ("DLE") technology to complement the existing conventional solar evaporation process. The Company and Ganfeng have conducted significant early works studies at the Pastos Grandes Project and Ganfeng's adjacent Pozuelos project, respectively. As a result, there is a rich data set that can be used to produce a comprehensive development plan. The Company also continues to investigate measures by which it can leverage the Company's experience and learnings from development of the Cauchari-Olaroz Operation.

The offtake rights for the Pastos Grandes Project remain uncommitted, which will allow the Company to explore opportunities to bring in new customers and financing to accelerate and support development of the global lithium chemical supply chain.

Property Description and Location

The Company acquired the Pastos Grandes Project from Millennial Lithium in January 2022. The Company subsequently acquired additional mining concessions (LAC Norte and Sur) during 2022.

The Pastos Grandes Project is situated within the Department of Los Andes, approximately 10 km south of the village of Santa Rosa de Los Pastos Grandes, and 130 km west of the city of Salta, the capital of the Salta Province in Argentina. The center point of the Pastos Grandes Project is situated at approximately 3,428,966 mE, 7,283,194 mN (POSGAR 04 / Argentina zone 3). The Pastos Grandes Project encompasses a surface area of more than 24,000 hectares in the hydrographic basin of Salar de Pastos Grandes at an elevation of roughly 3,785 masl.

The Pastos Grandes Project site is situated near Highway 129 which connects 40 km north with Highway 51. Highway 51 traverses from Salta to the international border with Chile at the Sico Pass and connects further west to the major mining center of Calama, as well as the ports of Antofagasta and Mejillones in northern Chile. Both ports are major transportation hubs for the importation of mining equipment and the exportation of mineral commodities. The Pastos Grandes Project is in the vicinity of the existing railroad between Salta and Antofagasta that is administrated by two different companies: The Chilean Ferrocarril Antofagasta - Bolivia (Luksic Group) and the Argentinean state owned Ferrocarril Belgrano. It consists of a narrow-gauge railway connecting Antofagasta (Chile) on the Pacific coast to the northern part of Argentina with connections to Buenos Aires on the Atlantic coast. The connection between Pocitos - Antofagasta has been reinstated in cooperation between the regional governments and is currently active shipping product for a lithium operation in Salar del Hombre Muerto.  A natural gas line (Gas de la Puna) with a distribution terminal is in the village of Pocitos. Here gas is redistributed to lithium operations in the Puna currently being developed. It is planned that the Pastos Grandes Project will connect to this terminal with a dedicated pipeline for the supply of natural gas during operations.  It is expected that all industrial water supply requirements for the Pastos Grandes Project can be developed from groundwater resources hosted in the alluvial fans surrounding Salar de Pastos Grandes. The Pastos Grandes Project controls sufficient surface rights to execute the contemplated mining and processing activities.

Mineral Tenure

Argentine Tenure Regime

The Argentine mining regulations recognize two types of tenements. Cateos, also known as Exploration Permits, grant permission to explore the tenement for a period that is proportional to its size. The other type of tenement is known as "Mines" or "Claims". This kind of permit grants authorization to exploit the tenement, subject to regulatory environmental approval. These licenses have no time limit, provided that the property holder fulfils their obligations under the Mining Code. These obligations include:

● Paying the annual rent (canon);

● Completing a survey of the property boundaries;

---

● Submitting a mining investment plan; and

● Meeting the minimum investment commitment.

The mining concessions comprising the Pastos Grandes Project is registered as "Mines" under the file numbers listed in the table below in the Department of Los Andes (Salta Province). The properties the Company recently acquired through the acquisition of Arena Minerals are not included in this list.

Through its 85.1% percent ownership of PGCo (which ownership interest is subject to the Pastos Grandes Transaction; see "Item 4. - Property, Plants and Equipment - Recent Developments"), the Company controls the Pastos Grandes Project. There are no known obstacles to PGCo maintaining ownership on these titles, with the caveat (i) on those areas that were claimed by multiple parties that a lottery may be held, and that area be awarded to a third party (Title 37). All patent (canon) payments are up to date on all those claims where the patent is due. All claims are free from any evidence of mortgages, encumbrances, prohibitions, interdictions, or litigation.

Royalties

In addition to certain royalties mentioned above, the Argentine federal government regulates ownership of mineral resources, although mineral properties are administered by the provinces. In 1993 the federal government established a limit of 3% on mining royalties to be paid to the provinces as a percentage of the "pit head" value of extracted minerals. ANG is expecting a 3% royalty payable to the Salta Province based on earnings before income tax if a brine mining operation is established.

History

Borate mining has taken place in the general vicinity of Salar de Pastos Grandes since the early 1960s. Borax Argentina, recently divested by Allkem Limited, extracts colemanite, hydroboracite, and ulexite from the Sijes Formation located on tenements situated on the southern and eastern edges of the Pastos Grandes basin. These minerals are processed at the Sijes borates plant.

In 1979, DGFM (a state-owned Argentine arms manufacturer) conducted a lithium exploration program that covered several salars in north-western Argentina, including Salar de Pastos Grandes. The exploration included surface mapping and sampling of six brine samples from surface, eight from hand-dug pits, and four from streams around the Salar de Pastos Grandes. The sampling campaign found lithium and potassium concentration anomalies with average values of 384 parts per million (ppm) Li and 4,066 ppm K for the pit samples, and 327 ppm Li and 3,518 ppm K for the surface samples. The stream samples reported lithium concentration below detection limits.

In 1987 ULEX S.A.  began borate production at the Sol de Mañana Mine in the south-eastern portion of the Salar near the Rio Sijes reaching a production of near 1,000 tonnes of colemanitehydroboracite- ulexite per year (Hains et al., 2018). Tramo SRL has mined borates (colemanite) at the Quebracho property on the southern border of Salar de Pastos Grandes and common salt (halite, NaCl) on the salar's surface since 2006. Other smaller mining companies have also carried out salt exploitation over various properties in the Salar.

During 2011 and 2012, Eramet SA ("Eramet") through its subsidiary Eramine Sudamerica SA ("Eramine") carried out exploration activities in the Salar de Pastos Grandes including geophysical surveys (VES, TEM and Controlled Source Audio Magnetotellurics survey ("CSAMT") campaigns, all as defined below), drilling (exploration and production wells to maximum depth of 160 m), testing, and geochemical sampling. This work has been referred to as the Stage One of investigation of the Pastos Grandes Project and identified a lithium-enriched brine aquifer with lithium concentrations ranging between 330-560 mg/L and a ratio Mg:Li of between 5.35 - 7.87.

LSC Lithium Corporation ("LSC Lithium") undertook an exploration program between 2016 and 2018 focused on the western and central portion of Salar de Pastos Grandes.

Millennial Lithium conducted an extensive program of field work across the Salar de Pastos Grandes from 2016 to 2021 known as the Stage Two and Three investigations of the Pastos Grandes Project. In January of 2022, the Company completed the acquisition of Millennial Lithium including the Pastos Grandes Project. The Company is currently carrying out additional works, engineering and other optimization studies. In addition, in connection with the Pastos Grandes Transaction, the Company announced that Ganfeng, with support of the Company, will undertake preparation of a regional development plan for the Pastos Grandes basin, which includes the Pastos Grandes Project and the Sal de la Puna project and Ganfeng's adjacent Pozuelos project, and which is expected to be finalized in 2025.

Centaur Resources Ltd. ("Centaur") carried out lithium exploration activities on the 'Alma Fuerte' mining claim of its Sal de la Puna project immediate to the south and east of the Company mining claims during 2018/2019. This program included drilling of three boreholes including a pumping well to around 600 m depth, pumping tests, and seismic & TEM geophysical surveys.

Geological Setting, Mineralization and Deposit Types

Regional Geology

Tectonic Context

The main lithium-containing region of South America is in the Puna Plateau of the central Andes. The Puna Plateau is approximately 2,000 km long, 300 km wide and has an average elevation of 3,700 masl. The eastern volcanic arc and centres have been active from the Miocene to the present and are the source of mineralized fluids throughout the plateau. The uplift of the Puna Plateau is the result of the crustal shortening that occurred in the Tertiary and magmatic accumulation.

The section of the Puna which developed in Argentina shows distinct features of the Altiplano than those seen in Bolivia and Peru. This zone can be divided into Southern Puna and Northern Puna according to their relative position with respect to the Olacapato lineament. This lineament corresponds to a regional megafracture on a WNW-ESE course that crosses other geological provinces of the Andean axis. The observed geological differentiation in the upper crust is a response to the deep segmentation of the subducted Nazca plate which would condition a different metallogenic development. The southern Puna is considered the plateau region associated with the volcanic arc developed between 24" and 27" S and the Northern Puna to the region between 24" and 22" S.

The volcanic arc limits the Puna hydrological basin to the west while the Eastern Cordillera limits this basin to the east. Towards the Puna Austral (Southern Puna), a combination of east-west striking volcanic chains with uplifted blocks caused by north-south striking reverse faults limit numerous hydrological sub-basins, with numerous and extensive salt flats covering their bases, frequently surrounded by important alluvial systems. Thick sections of Neogene strata (up to 5 km) are present within depositional basins, which contain evaporites (mainly halite, gypsum, and borates) and alluvial clastic material with smaller tuff horizons. Exposed Neogene strata is present along the margins of the salars due to reverse faulting or as intra-basin uplift within the salt flats.

Stratigraphy

The units that outcrop in the region correspond only to rocks of Ordovician and Cenozoic age. The Ordovician outcrops are represented by leptometamorphic shales and greywackes, green to grey, strongly folded and fractured that make up the Cordón de Copalayo, on the western flank of the depression, as well as its basement. Additionally, Ordovician plutonites and metamorphites assigned to the Oire Eruptive Complex are found in a conspicuous northern prolongation of the Oire ridge and on the eastern edge of the depression.

In strong angular unconformity and with an inclination towards the east, a thick sequence of tertiary continental sedimentary rocks developed which outcrop across the width of the basin (17 km), although in many cases without continuity. Based on chromatic and lithological differences, these tertiary sedimentary rocks can be subdivided into Fm Geste, Fm. Pozuelos and Fm. Sijes, components of what are called the Pastos Grandes Group. Alonso and Gutierrez (1986) identified the Fm. Singuel and separated it from the top originally assigned to the Fm. Sijes of this thick sequence of sparsely consolidated conglomerates with increasing gradation.

Structures

The dominant structures in the Puna trending N-S to NNE-SSW are generally compressional or transgressive in nature formed mainly during the Neogene. Other structures are lineaments of regional magnitude, transversal to the Andean strike with a northeast and northwest direction along with displacements that occur in the strike direction and changes in the orientation of the Neogene folds and faults as well aligned volcanic flows of Cretaceous, Miocene-Pliocene and Quaternary ages. Some of the transversal lineaments have a well-documented pre-Cenozoic history, such as the Calama-El Toro- Olacapato lineament. South of this lineament, the deepest levels of the crust are exposed in both the Puna and Calchaquenia suggesting that the pre-Neogene deformation was dominated by vertical movements, descending towards the north. In addition, immediately north of the lineament, the western edge of the Cretaceous rift basin undergoes a marked westward displacement.

Local Geology

Based on the lithological descriptions of the drill core and cuttings together with the interpretation of the available geophysical information and field observations five major geological units were defined and correlated, these units were incorporated into a 3-D geological model of the Pastos Grandes sub-basin. The geological units are described hereafter:

Fluvial/Alluvial Unit

The Fluvial/Alluvial Unit is characterized by a heterogeneous sequence of alluvial and fluvial sediments of variable texture, dominated by clastic sediments formed by gravel and sand that surround the Salar de Pastos Grandes. These fractions may present low proportions of fine sediments (sands or clays) which develop mainly along the northern and southern edges of the Salar de Pastos Grandes, prograding in depth towards the center, to interdigitate with finer silt sediments formed by clay and sandy clays from the Central Clastics Unit.

Upper Clay Unit (Blanca Lila Formation)

Formed by a superficial sequence of clays with a wide distribution in the center-south of the basin, as well as in the western margins where, according to field observations, it occurs in outcrop. This clay dominated unit intercalates with layers of evaporites, halites and borates, while in the bibliography travertine and tuff horizons were also described.

Saline/Lacustrine Unit

Immediately below the Blanca Lila Fm and in the north-central sector from the surface, a thick halite sequence is recognized. This Unit is characterized by a massive and compact halite body with the presence of interstitial clastic material and occasional intercalations of finer levels of clay. The average thickness of this Unit is ranges between 200 m and 300 m, reaching maximum thicknesses of 700 m in the central- eastern sector of the basin, which is interpreted as an ancient depocenter.

Central Clastic Unit

This Unit consists of clay and clayey sands and occurs within the central sector of the basin underneath the halite deposits. This Unit is poorly characterized due to limited and low-quality borehole information, but seems to represent a distal sector of an alluvial fan and its interaction with marginal lacustrine deposits of the Salar de Pastos Grandes. Additional core drilling is planned  to improve the hydrogeological characterization of this Unit.

Base Breccia/Gravels Unit

Based on Millennial Lithium's lithological description, a sedimentary breccia unit of coarse fragments of silicified conglomerate and ignimbrites was recognized in borehole PGMW19-21. This Unit corresponds to intermixed levels of sand and gravel with a thickness of 200 m on the western edge of the basin and deepening towards the north-central limit of the model where due to limited information its thickness becomes uncertain.

Mineralization

The brines from Pastos Grandes are solutions saturated in sodium chloride with an average concentration of TDS of 302 g/L and an average density of 1.19 g/cm3. The other components present in the Pastos Grandes brine are K, Li, Mg, SO4, Cl and B with relatively low Ca. The brine can be classified as a sulphate-chloride type with anomalous lithium. Lithium concentrations in Salar de Pastos Grandes have an average value of 392 mg/L, with some samples reaching up to 700 mg/L.

The table below shows a breakdown of the principal chemical constituents in the Pastos Grandes brine including maximum, average, and minimum values, based on 605 primary brine samples collected between 2017 and 2022.

Hydrogeology

Salar de Pastos Grandes is a mature salt flat with a well-developed halite crust. In the central portion of the salar, the crust can reach a thickness of several hundred meters with a thin clay layer that is constantly being generated through evaporation in the shallower beds. The Salar de Pastos Grandes is the lowest topographic point in the Pastos Grandes basin. The salt flat itself is surrounded by alluvial fans which drain into the Salar de Pastos Grandes and tertiary rocks that may act as impermeable boundaries, although further hydrogeological characterization work of the Tertiary is recommended. The surface of the Salar de Pastos Grandes in the north is composed of mainly chloride facies (halite crust) with active evaporation occurring since the brine level occurs within 5 cm from the surface. The Salar de Pastos Grandes surface in the south is covered by the Blanca Lila Fm with an average thickness of 3 m. Depth to brine in the southern part of the Salar de Pastos Grandes is between 3 m and to 4 m, below the evaporation extinction depth that is estimated around 2.5 m.

Based on the interpretation of drilling and testing work in the basin, four hydrogeological units have been identified and are described below:

1. UH-1 Fine Grained Shallow Deposits: These sediments belong to the Blanca Lila formation and are in conformity with the underlying Saline Lacustrine Unit, reaching a maximum thickness of 30 m in the northeast of the Salar de Pastos Grandes. Because of the fine texture, permeability and storage properties for this Unit are estimated to be low with a hydraulic conductivity (K) ranging between 0.1 - 0.01 m/d, a specific storage (Ss) of 1x10-6 1/m and drainable porosity below 2%. Geophysics and field sampling suggests that this Unit is saturated with brine inside the Salar de Pastos Grandes and with brackish water around the margins.

---

2. UH-2 Evaporitic Deposits: Massive evaporitic unit intercalated with lenses of fine-grained sediments that can have a thickness up to 700 m. This relatively homogeneous Unit includes the saline lacustrine material that forms the surface of the salar nucleus and is overlain by the Blanca Lila Fm (UH-1) in the south. Based on drilling and testing results this Unit has a relatively low permeability and could limit hydraulic connectivity between the upper and deeper hydrogeological units in the basin. The hydraulic conductivity of this Unit is estimated to be lower than 0.01 m/d, the specific storage is estimated to be near 10-6 1/m and the specific yield could reach 4%. Geophysics and field sampling suggests that this Unit is saturated with brine.

3. UH-3 Alluvial and Colluvial Deposits: This hydrogeological unit includes the alluvial fans identified at the margins of the Salar de Pastos Grandes which are composed of unconsolidated gravels and sand. This Unit overlies and is in lateral contact with UH-2 and locally interfingers with UH-4. The hydraulic conductivity ranges between 30 m/d and 50 m/d. The average drainable porosity is 14%. Groundwater flow in the Alluvial and Colluvial Deposits is generally unconfined; however, locally semi-confined to confined flow conditions occur where this unit is overlain by UH-1 and UH-2. The unit hosts freshwater resources in the alluvial fans on higher ground above the margin of the Salar de Pastos Grandes and significant brine resources in the southern portion of the salar where it is partially overlain by UH-1.

4. UH-4 Lower Deposits: Overlaying basement rock, this hydrogeological unit includes the Central Clastics and Base Gravels. It is composed of sandy gravels with a high fraction of fine material in a sedimentary matrix and some clayey to silty lenses that decrease the bulk vertical hydraulic conductivity. This unit is constrained to the central portion of the basin, underlies UH-2, and is in lateral contact with the unconsolidated deposits of UH-3. The hydraulic conductivity of this unit is estimated to range between 0.1 - 1 m/d, the specific storage at 10-6 1/m, and the drainable porosity near 8%. This unit forms part of the confined lower brine aquifer from which future brine production will likely not affect the freshwater resources hosted in the alluvial system due to the overlying low-permeability halite unit.

Exploration

Various exploration programs were completed in Salar de Pastos Grandes between 2011 and 2021 by various owners prior to the Company.

Surface brine sampling

In 2011, Eramet took a total of nine samples from shallow hand-dug auger holes within the eastern section of the Salar de Pastos Grandes and the wetlands. Three brine samples toward the west of the Salar de Pastos Grandes had lithium concentrations near 600 mg/L and potassium concentrations near 7,000 mg/L while samples at the centre of the Salar de Pastos Grandes had lithium and potassium concentrations near 200 and 2,000 mg/L, respectively. LSC completed a second surface sampling program in 2016 which included 11 sampling sites (shallow brine bodies and hand dug pits) with similar results as Eramet in 2011.

Geophysical studies

Eramet (2011-2013)

---

Eramine carried out a TEM, VES, and CSAMT surveys in Salar de Pastos Grandes between 2011 and 2013. No information is available for the TEM survey. The objectives of these surveys were to map the occurrence of brine versus freshwater, and the distribution and relative continuity of lithological units.

Millennial exploration (2017 - 2019)

VES survey (2017)

Millennial Lithium conducted a VES survey in 2017 focused on the alluvial deposits in the northern portions of the Salar de Pastos Grandes. This study included 10 VES stations which were interpreted into 3 vertical sections to map the saline interphase, identify potential brine resources in the north, and help define new exploration drilling sites.

Seismic survey (2018 - 2019)

Millennial Lithium carried out a two-phase seismic investigation program during 2018-2019 to help refine the understanding of the lithology in the Salar de Pastos Grandes and help define new exploration targets. The seismic tomography survey provided valuable information on the vertical distinction and lateral continuity of lithological layers. Additionally, several structures were interpreted, especially in the north to south profile, suggesting north to northwest dipping beds.

Downhole temperature and electrical conductivity surveys

Down-hole electrical conductivity profiling was conducted in boreholes PGMW16-02, PGMW17-04b, PGMW17-05c, PGMW17-07d, and PGMW17-11 which were completed with 2-inch diameter PVC casing on completion of drilling. Temperature and electrical conductivity were recorded at 3 m intervals using an In-Situ brand Aquatroll 100 downhole probe and brine samples were taken to measure laboratory density.

The results showed a reasonably good correlation between the Aquatroll specific conductivity and the laboratory density measurements on the depth-specific samples.

LSC exploration (2017 - 2018)

VES survey (2017b)

LSC Lithium carried out a VES study in 2017 to map lithology and the freshwater/ brine interface. The survey consisted of 13 soundings. The results of this survey identified five geoelectrical units: 1) conductive gravels and sands; 2) a semi-conductive fine grained unit (silt and clays and/or halite gypsum and borates), probably related to the Blanca Lila Fm; 3) a highly conductive zone of evaporates and mixed halite/clastics saturated with brine; 4) a more resistive layer representing again the Blanca Lila Fm or other Tertiary sequences and; 5) a resistive zone interpreted as the hydrogeological basement composed of thick clastic facies (conglomerates) and/or facies of volcanic rocks (andesites).

Seismic survey (2018)

LSC undertook a seismic tomography survey consisting of six lines for a total of 15 km. The interpretation of the results of this survey was based on a combination of literature values, regional geological information and specific correlation to boreholes SPG-2017-02B and SPG-2017-04A and is summarized below.

To the west of the Salar de Pastos Grandes seven seismic units were identified without structure to a depth of 600 m: 1) dry alluvial deposits; 2) halite crust; 3) saturated sand, clay and/or organic material; 4) crystalline halite; 5) saturated sand, clay and/or organic material; 6) gravels and 7) breccia.

To the center and east of the Salar de Pastos Grandes 11 seismic units were identified without structure to a depth of 600 m, from top to bottom: 1) dry to partially saturated sediments and alluvial material (saturated sand, clay and/or organic material); 2) halite crust; 3) saturated sand, clay and/or organic material; 4) halite with scarce matrix; 5) halite with abundant matrix; 6) halite with scarce matrix; 7) sand; 8) alternation of halite and sand bands; 9) gravel, sand and/or clay; 10) halite with interbedded sand; 11) gravel and/or sand.

Centaur/Arena Minerals exploration (2018 - 2022)

TEM survey (2018)

---

Centaur conducted several TEM surveys to evaluate the presence of brine beyond the margins of the Salar de Pastos Grandes in the Corral Colorado river valley, the Sijes subbasin, and in the southern portion of the salar. The TEM lines in the north and east confirmed the existence of a deeper conductive anomaly associated with brine and the overlaying freshwater hosted in the alluvial sediments. The southern lines over the Blanca Lila Fm showed a conductive unit close to the surface interpreted as the halite unit saturated with brine, based on drilling.

Passive seismic survey (2019)

A passive seismic survey was conducted by Centaur in 2019 to map basement and confirm interpreted fractures to the south and east of the Salar de Pastos Grandes. This study consisted of 78 stations arranged in 10 east-west orientated lines (see figure directly above). The survey did not consistently identify basement rocks due to depth and the poor seismic contrast between the massive halite body and basement rocks.

TEM survey (2022a)

Arena Minerals carried out a TEM survey during 2022 along the eastern boundary of the Salar de Pastos Grandes to refine the delineation of the overburden and hydrogeological basement, and to further investigate the freshwater/brine interface in this portion of the Salar de Pastos Grandes based on Centaur's 2018 survey. The survey helped identify the limit between the unconsolidated sediments and basement rock. These results and interpretations were correlated to lithological information of boreholes DD-01, DD-02 and DD-03.

Company exploration (2022)

ERT survey (2022 b)

The Company conducted an ERT survey to refine the delineation of freshwater resources suitable for industrial water supply in the alluvial deposits in the north-eastern portion of the Pastos Grandes Project. The survey consisted of 12 lines with a vertical maximum resolution of 160 m - 200 m.

Three geoelectrical units were identified 1) fine grained sediments with abundant interstitial clay and saturated with brine of high electrical conductivity; 2) fine to coarse grained sediments saturated with water; and 3) medium to coarse grained sediments partially or not saturated.

Drilling

Three drilling campaigns have been carried out since 2011. Eramet conducted the first exploration program in 2011 including 11 shallow exploration boreholes (SW series), two diamond drill holes (DW01PGDDH and DW02PGDDH), four shallow exploration holes completed with 6-inch diameter casing (PMP series), and three exploration wells of varying depths completed with 6-inch diameter casing (DW03PG, DW04PG, DW05PG). Detailed information of these boreholes has not been published and is mostly unavailable, although maximum depths reached at this stage rarely exceeded 100 m. The second and third campaign conducted by Millennial Lithium included 32 brine exploration boreholes (PGMW16-01 through PGMW19-22), 6 freshwater exploration wells (PGWW18-01 to PGWW19-06) and 4 brine production wells (PGPW16-01 to PGPW18-17) with drilling depths of up to 600 m. Most of the monitoring wells were completed as piezometers with 2-inch diameter PVC slotted casing, while production wells were constructed with 6 to 8- inch diameter screened casing.

Arena Minerals and Centaur carried out drilling programs on the Sal de la Puna project in between 2018 and 2022. These programs consisted of two diamond core holes (DD-01 and DD-02), five combination core /rotary holes (PP-01-2018, PP-02-2018 and R-01 through R-03), two production wells (PP-03-2019 and PW-1), and several piezometer installations.

The objectives of the drilling program can be broken down into three general categories:

1. Exploration drilling to allow the estimation of "in-situ" brine resources: The drilling methods were selected to allow for 1) the collection of continuous cores to prepare "undisturbed" samples from specified depth intervals for laboratory porosity analyses and 2) the collection of depth- representative brine samples at specified intervals.

---

2. Test well installations: 8 rotary holes (PGPW16-01 to PGPW18-17; PGWW18-01 to PGWW19- 03, and PW-1) which were drilled and completed as production wells to carry out pumping tests and additional selective brine sampling. Monitoring wells were installed adjacent to most of these production wells for use during the pumping tests as observation points.

3. Pumping tests: Eight pumping tests have been completed in the Salar of Pastos Grandes. These tests included three short-term tests (PGWW18-02, PGWW19-02 and PGWW19-03), each lasting about one day and conducted on freshwater wells; three three-day tests conducted on brine wells (PGPW16-01, PGPW18-15 and PGPW18-17); and two long-term pumping tests (PGPW16-01 and PGPW17-04) with 23- and 30-day duration.

The table below provides summary information of the completed boreholes from 2016-2022.

Hydraulic Testing

Millennial Lithium completed eight pumping tests between 2017 and 2019. These tests included three one-day tests on the freshwater wells; three three-day tests on brine wells; and two long-term pumping tests (23- and 30- day duration) also on brine wells.

Brine Well Pumping Tests

PGPW 16-01 (2017)

A 3-day pumping test was carried out on well PGPW16-01 at an average pumping rate of 27.7 L/s. The configuration of the test and its results are shown in the table immediately below. The production well is screened across the saline halite unit and the underlying brine aquifer. This test included four observation wells but only SW03PG-1 (without completion information) reacted to pumping. Drawdown and recovery data were interpreted, respectively with Cooper & Jacob (1946) and Theis (1935) recovery solutions leading to a hydraulic conductivity (K) estimate of about 3 m/d.

PGPW 17-04

---

A 23-day pumping test was completed on PGPW17-04 at a pumping rate of 15.23 L/s in 2019. The production well is screened across halite, sand, and silt; because of the low permeability of the halite it is believed that the drawdown response is mainly related to the unconsolidated clastic sediments beneath it. Drawdown data during the pumping stage was discarded due to an apparent non-related water level recovery observed during test. Therefore, only recovery data were adjusted to the Theis (1935) recovery solution, leading to a transmissivity estimate of 40 m2/d, or a hydraulic conductivity 0.12 m/d assuming a saturated thickness of 329 m. The configuration of the test and its results are shown in the table immediately below.

PGPW 18-15

A pumping test (variable and constant rate, and recovery) was carried out in PGPW18-15 during April of 2019. The well was screened in the same lithological unit as PGPW-17-04. The configuration of this test and its results are shown in the table immediately below. Water levels during the test were also monitored in PGMW18-15. The hydraulic conductivity was estimated to range between 0.15 - 0.22 m/d.

PGPW 18-17

A three-day pumping test was conducted on well PGPW18-17 well with an average pumping rate of 19.4 L/s. The configuration of the test and its results are shown in the table immediately below. Drawdown data was measured only in the pumping well and was adjusted to the Cooper and Jacob (1946) and Theis (1935) recovery solutions. The estimated hydraulic conductivity ranges between 0.17 - 0.22 m/d, which is consistent with previous results for the same lithologies in the Salar de Pastos Grandes.

PGPW 16-01 (2019)

A 15-day pumping test was conducted on well PGPW16-01 at an average pumping rate of 23.2 L/s during May 2019. The results of this 2019 test are summarized in the table immediately below and are quite similar to the results of the 2017 test. Drawdown and recovery data were interpreted with the Theis (1935) recovery solution, leading to a hydraulic conductivity estimate of about 2 m/d.

Pumping Tests Conducted in Freshwater Wells

PGWW18-01

A variable rate and a 1-day constant rate tests with an average flow rate of 0.85 L/s was carried out on well PGWW18-01 in May 2019. No hydraulic parameters could be obtained from this test because of the short test duration and the low pumping rate as shown in the table immediately below.

PGWW 19-02

Well PGWW19-02 was pump tested in 2019 (a variable rate, a constant rate and a recovery). The layout of this test and results are shown in the table immediately below. Drawdown and recovery trends were adjusted with the Cooper and Jacob (1946) and Theis (1935) recovery solutions, respectively. Estimated hydraulic conductivity values ranged from 20 to 60 m/d which is considered reasonable for these types of coarse-grained unconsolidated sediments. The pumping test configuration didn't include observation wells; therefore, no storage estimates could be obtained.

Sampling, Analysis and Data Verification

Millennial Lithium drainable porosity analysis (2016-2019)

Samples were obtained from 'undisturbed' core during the 2016-2019 Millennial Lithium drilling programs and analysed for drainable porosity by Core Laboratories-Petroleum Services ("Corelabs") in Houston, Texas. In addition, rotary drill cuttings were sent to Geosystems Analysis ("GSA") in Tucson, Arizona for repacking, triaxial testing, and drainable porosity analysis. Both Corelabs and GSA are independent laboratories and have no relationship with the Company.

Both Corelabs and GSA offer advanced petrophysical and geological analysis and interpretation services for core samples. These laboratories operate in compliance with ISO 9001:2008 Certification ensuring that processes and procedures adhere to internationally recognized quality standards. The analytical procedures for determining drainable porosity for each laboratory are further described below.

Corelabs drainable porosity analysis are based on centrifuge methodology and involve the following:

---

1. 38 mm (1.5-inch) diameter cylindrical plugs were cut from the sample material.

2. Samples were frozen with dry ice to maintain their integrity, if required.

3. Sample weight and thickness were measured.

4. The plugs were encapsulated in Teflon and nickel foil as required, and nickel screens were placed on the ends of the plugs. The encapsulated samples were then weighed.

5. Bulk density was calculated as: (Mass of plug before encapsulation) / (Calliper bulk volume).

6. The plugs were placed in brine and saturated under vacuum to ensure full saturation. Corelabs utilized a standard sodium chloride brine with a NaCl concentration of 244,000 ppm with a density of 1.184 gm/cm3.

7. The weight of the saturated cores was recorded.

8. The samples were desaturated in a high-speed centrifuge for 4 hours. Spin rates were calculated to provide a drainage pressure of 1 pound per square inch (psi) for poorly cemented or loose sands and 5 psi for clay and halite.

9. The drainage was collected, and the volume was recorded. The effluent was saved for possible analysis. However, it should be noted that the fluid collected from these cores may not be representative of in situ brines if re-saturation with NaCl was required.

10. Plugs were removed from the centrifuge and weight was recorded. Drained fluid volume was calculated as: (saturated plug weight - drained plug weight) /1.184. Drainable porosity was calculated as (Drained fluid volume) / (Calliper bulk volume).

11. Total porosity was calculated after drying the samples for 5 days at 115.6 degrees Celsius to record dry weight.

12. All weight loss is assumed to be water lost from pore space where volume of water loss is calculated as: ((Drained plug weight) - (Oven-dried plug weight))/ (Water density of 1 g/cc).

13. Total porosity is calculated as ((Drained fluid volume) + (Oven drying fluid loss))/ (Calliper bulk volume).

GSA drainable porosity analysis procedures for repacked sediment samples include the following steps:

1. All loose and sandy samples were packed into test cells with moderate effort without prior knowledge of bulk density or other consolidation tests. Additional repacking was performed on some samples with minimum and maximum effort to evaluate the effectiveness and variation of hand-packing at higher and lower densities. Bulk densities approximately 0.1 g/cm3 lower and higher than the initial density were achieved, respectively.

2. The sandy material was packed into a stainless-steel ring in several small lifts. The weight and packing height of the first lift were used to guide the subsequent lifts to ensure consistent density packing. Scales were used to track the equipment, cell, and sample weights throughout the process, and the final packed and assembled core weight was recorded.

3. Plastic air tubing, approximately 6 inches in length, was inserted into the top of each core to monitor saturation and prevent brine solution spillage. The cores were then assembled and saturated slowly from the bottom up using provided brine. A combination of gravity feed and vacuum suction was used to achieve the target saturation. If the target saturation could not be reached using gravity feed alone, vacuum suction was applied. The saturation process lasted for up to 24 hours. Once fully saturated, the cores were closed at the bottom with a hose clamp to prevent brine solution loss and disconnected from the saturation setup.

4. Each cell assembly underwent three pressure steps after being transferred to a test rack. The first step, at 0 mbar pressure, lasted for 24 hours and was applied to remove excess saturation solution. To approximate the release of brine solution at 120 mbar and 1/3 bar of the brine solution, two sequential pressure steps were used at 120 mbar and 1/3 bar, respectively. The 120-mbar pressure step was maintained for 2 days, and the 1/3 bar was continued for another 2 to 4 days. Weight measurements were taken twice a day to determine the loss of brine solution over time. After the final step the cores were disassembled and samples were oven dried to determine total porosity following the procedure described in MOSA, 2002, Part 4 Ch. 2, 2.3.2.1.

5. To estimate the brine solution release volumes at the 120 millibar and 1/3 bar pressure steps, the difference was calculated between the measured total porosity and the moisture retained after the pressure plate measurements as outlined in MOSA (2002), Part 4, Chapter 3, Section 3.3.3.5. The solution's release volume obtained at 1/3 bar was regarded as an approximation of the maximum solution drainage that could occur under gravity or pumping conditions, and hence was used to determine the specific yield.

---

After completing the tests, the estimated particle density and weight data from core samples at various pressure steps were entered into a spreadsheet. The spreadsheet was programmed to automatically calculate the salt weight left in the sample after drying, estimated porosity, and water content change. Furthermore, particle density was optimized during data processing by utilizing all prior test measurements and using a solver in Microsoft Excel. The laboratory report presented the calculated particle density for each sample.

Arena Minerals drainable porosity samples (2021-2022)

36 samples from the Arena Minerals 2021-2022 drilling program were sent to GSA for drainable porosity analysis. All samples were tested using the 'Rapid Brine Release' method to measure specific yield ("Sy") and total porosity ("Pt.") Brine release drainable porosity was measured at 120 mbar and 333 mbar of pressure, where:

● Brine release at 120 mbar represents drainable porosity from sand dominated sediments and Rapid Brine Release ("RBR") from macropores.

● Brine release at 333 mbar represents the Sy for intermediate to finer texture sediments.

Brine release values at 120 mbar were provided for reference and 333 mbar values were presented as the estimated Sy (drainable porosity). A subset of paired samples representative of the range in lithology types were selected by Atacama Water  and GSA for testing using the Relative Brine Release Capacity ("RBRC") method by Daniel B. Stephens & Associates, Inc. ("DBSA") in Albuquerque, NM. The goals of the test work were to provide Sy and Pt values for each sample, summary statistics of Sy and Pt by lithological group, and to compare the Sy and Pt values derived for paired core samples using the RBR and RBRC methods.

The table immediately below lists the physical properties analyses carried out by GSA. In addition to the RBR testing, physical property tests were run by GSA to assist in lithologic characterization and interpretation of results including bulk density testing (ASTM D2937-17e2) on all RBR samples.

Three packing methods were used to prepare RBR core samples:

1. Stainless steel rings were pushed into intact sediment cores to preserve the structure and retain the original bulk density and porosity distribution in the sample.

2. Sediment cores with loose sediment and/or disturbed samples were extruded, and voids were filled in using moderate packing effort to eliminate voids in the test samples.

3. Most solid halite and/or rock cores were cut with a rock saw to fit GSA's RBR test cells and then fit into a 6.35 cm diameter ring and sealed as discussed below.

RBR test cells were prepared by placing a pre-wetted micro-pore membrane (rated 1,200 mbar air entry value) into the bottom PVC cap. This membrane maintains a permeable saturated bottom boundary for solution flow and prevents air entry under the target air pressures applied during RBR testing. The PVC caps contain gaskets to create an air-tight test cell that maintains constant air pressure and allows continuous solution outflow through the membrane.

The RBR method is based on the moisture retention characteristic method using the Tempe cell design (Modified ASTM D6836-16), whereby Sy is determined by applying pressures equivalent to gravity drainage to the Test Cell and measuring the amount of brine solution released. Pt is also measured in the RBR method, and is equal to the sum of Sy and Sr.

Each saturated RBR test cell was transferred to a test rack for the pressure extraction procedure where no pressure was applied for one day to remove any excess brine solution due to core over-saturation. Two sequential pressure steps were used to approximate brine solution release at 120 mbar and 333 mbar of matric potential (MOSA Part 4 Ch. 3, 3.3.3.2).

The 120-mbar pressure step was maintained for at least two days, and the 333-mbar pressure step was continued for another two to four days. Core assemblies were weighed prior to saturation, after saturation, and then two times daily to determine brine solution loss over time.

All samples were oven dried for three days at 60°C and one day at 105°C after the final step to determine the specific retention ("Sr"), dry bulk density, and Pt (MOSA Part 4 Ch. 2, 2.3.2.1), where Sr is the volume of water retained by the sample under 333 mbar soil water potential. This drying approach allowed for quantification of the amount of moisture lost due to crystalline water present in gypsum.

Brine solution release volumes at the 120 mbar and at 333 mbar pressure steps were estimated by the weight of brine lost between the initial cell assembly mass and the mass after each pressure plate step divided by the brine specific gravity (Equation 2, MOSA Part 4 Ch3, 3.3.3.5):

𝑆𝑦	=	𝑤𝑠 − 𝑤333 𝑚𝑏𝑎𝑟
		𝐴 ∗ 𝐿 ∗ 𝐵𝑠𝑔

where 𝑤𝑠 is the saturated weight, 𝑤333 𝑚𝑏𝑎𝑟 is the weight at 333 mbar, A is the sample core area, L is sample length, and Bsg is the specific gravity of the brine solution. The Sy is assumed to approximate the solution release volume from saturation to 333 mbar. Particle density was estimated from the measured porosity and bulk density according to:

Brine samples

Depth-specific brine samples were collected during core and rotary drilling by packer-system, bailing, or drive-point sampling. Bulk (compound) brine samples were obtained during pumping tests on selected exploration wells.

● Depth-specific packer sampling was the primary method used to collect brine samples during the drilling programs for Phase II and III (2016-2020). Most samples were obtained during drilling, although some were also taken after drilling had concluded. Samples were considered acceptable and representative of the depth interval only if they showed no, or minimal traces of drilling mud. The intervals were typically 3 m long and determined by the site geologist after inspecting drill cores or at predetermined depths. However, the interval length may vary depending on the specific circumstances of a given hole or interval, such as borehole stability. To ensure accurate sampling, intervals were flushed out multiple times before collecting the actual sample. The flushed brine was then collected in a barrel, and the time taken to fill the barrel was recorded.

● Drive-point sampling: five brine samples were collected using this method where a drive-point was installed onto BT-sized drill rods after removing the core barrel. The drive-point was then lowered past the drill bit with the help of a drop hammer and an impermeable diaphragm was used to prevent filling of the drill rods during the descent. Once the desired depth was reached, an electric water level sounder was used to confirm that the interior was dry before perforating the diaphragm using a weighted pin lowered with the wireline. This piercing allowed the brine to flow into the drive point and fill the BT rods and collect the samples with the use of a bailer.

● Bailing: the borehole was purged by bailing up to three well volumes of brine from the drill casing as calculated from the water level measurement, prior to collecting the final brine sample from the bottom of the hole. The final brine sample was discharged from the bailer into a 20-liter clean bucket from which one-litre sample bottles were rinsed and filled with brine. Each bottle was taped and marked with the borehole number and depth interval. A small sub-sample from the bucket was used to measure field parameters (density, electric conductivity, pH and temperature) at the wellhead.

● Samples from pumping tests: This method involved collecting samples directly from the discharge pipe at regular intervals during pumping tests. Temperature and density were recorded on internal field sheets.

Regardless of the sampling method, samples were collected in 20-litre containers that were washed with distilled water and rinsed with brine several times prior to filling. The temperature and density were recorded before filling 1-litre sample bottles which were also flushed with brine from the 20-litre container. The sample bottles were then sealed with a secure screw top to prevent leakage and labelled clearly with their identification number. Samples did not undergo any further preparation before being shipped to their respective laboratories.

After the sampling process the site geologist would retain possession of the brine samples until they were delivered to the office for shipment to the assay laboratory. Once at the office, duplicates, blanks, and standards were inserted into the assay batches before being sent to the laboratory. Prior to shipment all samples were kept under controlled temperature conditions.

The chemical analysis of brines was conducted by two reputable laboratories: SGS Argentina S.A ("SGS") and Norlab S.R.L, the later partnered with Alex Stewart Assayers ("ASANOA"). The mentioned laboratories have extensive experience analysing lithium-bearing brines and hold accreditation to ISO 9001 standards and follow the ISO 17025 guidelines. SGS and ASANOA are independent laboratories and have no relationship with the Company.

For the primary constituents of interest, including boron, calcium, potassium, lithium, and magnesium, both Alex Stewart and SGS utilized Inductively Coupled Plasma Analysis as the analytical technique, with samples diluted 100:1 prior to analysis. A summary of the analytical methods employed by each laboratory for each physicochemical parameter and analyte is shown in the table immediately below.

Drainable porosity QA/QC

Five duplicate samples were sent to Daniel B. Stephens & Associates, Inc ("DBSA") to serve as check samples to test for accuracy within the drainable porosity analysis. Summary statistics for paired samples by GSA lithologic category for Pt and Sy are provided in the two tables below. QA/QC testing was run on subsamples from the same core, but not on identical samples. Minor differences in material type (sand/silt/clay content) and core physical structure (bulk density, degree of cementation, rock content, macropore content) may result in discrepancies between laboratory measured values.

Variations can likely be attributed to sample heterogeneity within cores which result in subsamples with slightly to significantly different material properties, and differences in laboratory methods such as testing duration. The Sy values measured by GSA were often considerably higher than the Sy values measured by DBSA, particularly for the 333 mbar RBR measurement (see table below). Differences were most pronounced for halite samples due to lithological variability within the group (one crystalline sample with large crystals and one massive to crystalline sample with very scarce matrix).

In the absence of sample heterogeneity, differences are likely attributable to testing equilibration time and testing method. DBSA's RBRC method only applied 333 mbar of equivalent pressure for 24 hours and did not use a filter paper to prevent air moving through samples, whereas GSA's RBR testing was run at 120 mb for two days and then 333 mbar for two to four days no air was allowed to move through samples. Therefore, the lower Sy values reported by DBSA may be due to the samples not reaching equilibrium over the testing period. This may be most pronounced in materials with a greater predominance of macropores such as sands. It should be noted that Sy values measured at 120 mbar were generally in better agreement with DBSA's measured Sy values for all sediment lithological groups (see table below).

---

Specific gravity was higher for the RBR DD-01 451-451,2 sample (SG = 2.29) compared to the RBRC sample (SG = 2.13). Comparison of average values by lithological group was also limited due to small sample number. Average Pt values measured using the RBRC method (DBSA) were 7% lower for the clastic material group and 129% lower for the halite group. Average Pt values were considerably higher for the clastic group (0.24), with the halite group having a mean Pt value of 0.02.

There was general agreement between the total porosity data (R2 = 0.85). Correlation was slightly lower for the specific yield data (R2 = 0.80). The slope of the line was relatively high, indicating that GSA Sy values were approximately 35% higher than those reported by DBSA. The adjusted correlation coefficient between RBRC Sy and the drainable porosity at 120 mbar was R2 = 0.80.

All the samples tested for Sy fell below the 1:1 line indicating that GSA measured Sy values were typically higher than DBSA measured Sy values. In contrast, while three Pt points were scattered below the 1:1 line, two clastic material samples were plotted on the 1:1 line meaning the measured Pt values were similar for both laboratories.

There is acceptable variation between the laboratories for samples in the clastic material classification, but unacceptable variation for samples in the halite classification.

Brine QA/QCQA/QC procedures were implemented for laboratory chemistry analysis of brine samples obtained during drilling and pumping activities by Millennial Lithium, Arena Minerals, and Centaur. Each QA/QC program involved randomly inserting duplicates, check samples, field blank, and standards, with the following percent of quality control samples for each party: 21% for Millennial Lithium, 21% for Arena Minerals and 17% for Centaur. The purpose each QA/QC program was to confirm the accuracy and precision of the analysis, as well as to detect any potential contamination of the samples.

---

ASANOA was the primary laboratory used by Millennial Lithium while SGS was used as the secondary lab for check samples. This arrangement was in place until August 21, 2017, when Alex Stewart was replaced by SGS as the main laboratory. No registered secondary lab was used for check samples. Arena Minerals used SGS as their primary laboratory throughout the 2021/2 campaign, while ASANOA was used as the main lab for Centaur throughout the 2018/9 campaign.

Accuracy which is the closeness of measurements to the "true" or accepted value was monitored by the random insertion of standards, and the implementation of check samples analysed by a secondary, independent laboratory. Precision, the ability to consistently reproduce a measurement in similar conditions, was monitored by submitting blind field duplicates to the laboratory, monitoring any variability in the sampling and analytical program. Contamination which is the transference of material from one sample to another was measured by inserting blank samples into the sample stream. By implementing a QA/QC program that monitors these three factors, it is possible to ensure the reliability and accuracy of the laboratory results.

Millennial Lithium duplicate brine samples

To ensure the laboratory's precision, duplicate brine samples were submitted to the same facility. Millennial Lithium's Phase II and Phase III exploration programs included a total of 51 duplicate samples, some of these also used as check samples. 16 duplicates and their original samples were submitted to ASANOA (Alex Stewart), while 35 were submitted to SGS. The following two tables list the main statistics regarding the duplicates versus their original samples for lithium and potassium for each laboratory.

---

The assay results for duplicate samples at both ASANOA and SGS laboratories demonstrate a high degree of precision and consistency for key parameters of lithium and potassium. The highest Relative Percent Difference ("RPD") is only 2% for ASANOA and 0.5% for SGS. This is significantly lower than the commonly accepted 10% cut-off and suggests that the laboratory's analytical procedures are consistently producing results that are in close agreement with each other.

Millennial Lithium check samples

To test the laboratory's accuracy, samples were randomly selected and analysed at a secondary and independent laboratory - SGS. It's important to note that this only occurred before August 21, 2017, when SGS replaced Alex Stewart as the main laboratory. Since that date, no secondary laboratory has been registered for check samples. Millennial Lithium's Phase II and III exploration programs included 29 check samples to both primary and secondary labs. The main statistics regarding the check samples for lithium and potassium are listed in the table below:

Statistical analysis of check samples - ASANOA & SGS

Statistic	ASANOA-Li (mg/L)	SGS-Li (mg/L)	ASANOA-K (mg/L)	SGS-K (mg/L)
Count	29.0	29.0	29.0	29.0
Min	0.5	10.0	2.5	10.0
Max	554.4	714.0	5,424.3	7,740.0
Mean	468.8	543.9	4,779.2	5,916.2
Std Dev	104.1	123.8	970.3	1,248.8
RPD	14.8		21.3

The assay results for check samples between ASANOA and SGS fall within a 20% relative difference for lithium, but slightly over 20% for potassium. A RPD over 20% indicate that there may be an issue with the accuracy of one or both laboratories testing methods, but this cannot be determined solely by the RPD value, and further investigation is needed to identify the cause of the discrepancy. The RPD value for lithium of 14.8% is within the accepted 20% cut-off, but still suggests there is some difference between the results obtained by the two labs.

The check samples for both lithium and potassium show a failure rate that exceeds the accepted 10% cut- off. However, one of the three failures for lithium falls only marginally beyond the failure line which, if considered acceptable, would result in a failure rate of 6.9%. In contrast, the failure rate for potassium is 58.6%, with several samples falling beyond the failure line, indicating an unacceptable level of variation.

Millennial Lithium field blanks

To measure potential contamination 32 blank samples consisting of distilled water were inserted into the sample stream and sent to the laboratories for analysis. ASANOA received 10 blanks, while SGS received 22. Neither laboratory detected any lithium in the samples, although traces of potassium were detected by ASANOA. It is important to note that the detected potassium concentrations were below the standard safe limit, which is generally considered to be three times the detection limit.

Millennial Lithium standard samples

The Millennial Lithium sampling program utilized two types of standards. The first standard, 'RR', consisted of a large sample of brine collected from the Salar de Pastos Grandes during testing at well PGPW16-01 with the concentrations being obtained from a round robin style quality control check. Five RR standards were sent to ASANOA for analysis while 26 samples were sent to SGS. The concentrations (best values) of the standard obtained through the round robin are shown in the table below.

Element concentrations (best values) for Standard RR - Millennial Lithium

Sample	Li (mg/L)	Ca (mg/L)	Mg (mg/L)	B (mg/L)	Na (mg/L)	K (mg/L)	Density (g/mL)	EC (mS/cm)	TDS (mg/L)
PGS17153	450.2	618.8	3,033.9	774.9	107,255.0	4,890.0	1.2	189.0	334,800.0

The second type of standard, 'INBEMI', consisted of a synthetic solution prepared by the National University of Salta. INBEMI standards were only sent to SGS for analysis, amounting to a total of six samples. The concentration values for this standard are reported in the table below.

Element concentrations for Standard INBEMI ML

Sample	Li (mg/L)	Ca (mg/L)	Mg (mg/L)	B (mg/L)	Na (mg/L)	K (mg/L)	SO4 (mg/L)	Density (g/mL)
PGS17153	295.0	440.0	189.0	532.0	75,518.0	3,188.0	189.0	1.2

The RR standards analysed by ASANOA show that none of the lithium nor potassium values fall outside the ± 2 standard deviations from the mean. Additionally, all lithium values fall within the ± 5% range of the reference values while only one potassium value falls outside this range. There were not enough INBEMI standard samples analysed by ASANOA to conduct a graphical analysis as the moving average does not have enough data.

Notably, a bias check for the assay results revealed a negative bias ranging from -3.1% for Li to -5.7% for potassium indicating that the measured values are consistently lower than the expected or reference values. However, this detected bias is well below the accepted 10% and is not considered to be significant.

The RR standards analysed by SGS show that 6 out of 26 samples had a bias over the accepted limit of 10% bias lithium with no outliers and a total relative bias of -1.9% which is considered acceptable. Similarly, the potassium samples present 4 out of 26 values over 10% bias with one outlier, and a total relative bias of -3.1%, also deemed acceptable.

Regarding the INBEMI standards analysed by SGS, 2 out of 6 lithium samples showed a bias over 10% with no outliers and a total relative bias of 0%. For potassium samples show 1 out of a total of 6 had a bias over 10%, with no outliers and a total relative bias of 0%.

In summary, while some individual samples showed a bias beyond the generally accepted 10% limit, the overall bias for both lithium and potassium within the standard samples analysed by both laboratories is considered acceptable with the highest being -5.7% for lithium within the RR standards assayed by ASANOA.

Arena Minerals duplicate brine samples

SGS was used as the main assay laboratory by Arena Minerals and to ensure that the precision of the lab was acceptable, a total of 9 duplicate brine samples were submitted. There were no check samples used during the Arena Minerals drilling campaign due to COVID-19 related issues. The table below lists the main statistics regarding the duplicates for lithium and potassium.

Statistical analysis of duplicate samples - SGS

Statistic	Li (mg/L)	Duplicate Li (mg/L)	K (mg/L)	Duplicate K (mg/L)
Count	9.0	9.0	9.0	9.0
Min	33.6	31.9	197.0	177.9
Max	658.8	657.8	6022.9	6075.6
Mean	419.1	413.8	3726.1	3686.1
Std Dev	185.0	183.3	1788.9	1757.4
RPD	1.3		1.1

The assay results for duplicate samples at SGS demonstrate a high degree of precision and consistency for key parameters of lithium and potassium. The RPD is low, with values of only 1.3% for lithium and 1.1% for potassium. These are significantly lower than the commonly accepted 10% cut-off and suggests that the laboratory's analytical procedures are consistently producing results that are in close agreement with each other.

There were no failures for neither lithium nor potassium within duplicates analysed by SGS. The generally accepted threshold for failure rates is 10%, so duplicates are not only considered acceptable, but the lack of failures suggests high precision within the SGS laboratory for the current project.

Arena Minerals field blanks

To measure potential contamination within the sampling process a total of six blank samples consisting of distilled water were inserted into the sample stream and sent to the SGS laboratory for analysis. Neither lithium nor potassium were detected in any samples, therefore all concentrations were below the standard safe limit, which is generally considered to be three times the detection limit.

Arena Minerals standard samples

The Arena sampling program utilized two different standards, both obtained from brine within Salar de Pastos Grandes and named STD-1 and STD-2. Six samples were sent to SGS for analysis for each standard, amounting to a total of 12 standard samples. Their respective concentrations (best values) were obtained from a round robin style quality control check and are shown in the table below:

Element concentrations (best values) for Standards 1 & 2 - Arena Minerals

Sample	Li (mg/L)	Mg (mg/L)	Na (mg/L)	K (mg/L)
STD-1	645.7	2,395.5	55,435.8	6,709.8
STD-2	352.6	1,292.0	29,825	3,682.5

The STD-1 standard has no outliers nor values with a bias higher than 10% for neither lithium nor potassium, which suggests high accuracy and precision. Two lithium values fall outside the ± 5% variation from the reference value which still can be considered acceptable. The total relative bias for lithium is 6.7% and 2.6% for potassium, indicating that the measured values are consistently higher than the reference values, but are both within the acceptable 10% threshold. Finally, no values of lithium nor potassium fall outside the ± 2 standard deviations from the mean.

---

The STD-2 standard has no outliers but has one value with a bias higher than 10% for both lithium and potassium. Additionally, the same lithium and potassium value falls outside the ± 5% variation from the reference value, although can still be considered acceptable. The total relative bias for lithium is 7.3% and 3.6% for potassium indicating that the measured values are consistently higher than the reference values but are both within the acceptable 10% threshold. Finally, no values of lithium nor potassium fall outside the ± 2 standard deviations from the mean.

In summary, while some individual samples showed a bias beyond the generally accepted 10% limit, the overall bias for both lithium and potassium within the standard samples analysed by both laboratories is considered acceptable, with the highest being 7.3% for lithium within the STD-2 standard.

Centaur duplicate brine samples

ASANOA was used as the main laboratory by Centaur and to ensure acceptable precision within the lab, a total of six duplicate brine samples were submitted to the same facility. To date, there is no data regarding the use of check samples for the Pastos Grandes Project developed under Centaur. The table below lists the main statistics regarding the duplicates for lithium and potassium.

Statistical analysis of duplicate samples - ASANOA

Statistic	Li (mg/L)	Duplicate Li (mg/L)	K (mg/L)	Duplicate K (mg/L)
Count	6.0	6.0	6.0	6.0
Min	409.6	411.5	2,894.1	2,886.7
Max	548.3	627.9	5,093.1	5,213.7
Mean	507.3	543.2	4257.6	4617.1
Std Dev	52.5	65.8	880.1	824.0
RPD	6.8		8.1

The assay results for duplicate samples at ASANOA demonstrate a high degree of precision and consistency for key parameters of lithium and potassium. The Relative Percent Difference (RPD) is below the commonly accepted 10% cut-off for lithium and potassium, with values of 6.8% and 8.1% respectively. This suggests that the laboratory's analytical procedures are consistently producing results that are in close agreement with each other.

Out of the six duplicates tested, only one failure occurred for lithium while there were no failures for potassium. This translates to a 16.7% failure rate for lithium and 0% for potassium. The generally accepted failure rate threshold is 10% which means that duplicates are considered acceptable for potassium but unacceptable for lithium. However, it is important to note that the sample size taken under Centaur is limited, with only six duplicates assayed. Therefore, in this case, a single failure surpasses the 10% threshold. Taking this into consideration a 16.7% failure rate is deemed to be acceptable.

Centaur field blanks

To measure potential contamination a total of five blank samples consisting of distilled water were inserted into the sample stream and sent to ASANOA for analysis. Neither lithium nor potassium were detected in any samples, which means that all concentrations were below the standard safe limit, generally considered to be three times the detection limit.

Centaur standard samples

---

The Centaur sampling program utilized two different standards both obtained from brine within Salar de Pastos Grandes with their respective concentrations being obtained from a round robin style quality control check. These standards were named STD-A and STD-B, and three samples of the former were sent to the lab for analysis while only two of the latter were assayed. The concentrations (best values) for each standard obtained through the round robin are shown in the table below:

Element concentrations (best values) for Standards A & B - CR

Sample	Li (mg/L)	Mg (mg/L)	Na (mg/L)	K (mg/L)
STD-A	707.0	4,641.9	111,699.2	7,041.9
STD-B	370.5	2,444.3	58,074.0	3,543.1

The STD-A standard has no outliers nor values with a bias higher than 10% for neither lithium nor potassium, which suggests high accuracy and precision. Similarly, no lithium nor potassium values fall outside the ± 5% variation from the reference value, which is also a good indicator of accuracy and precision. The total relative bias for lithium and potassium is 0% indicating that the measured values are in accordance with the reference values. No lithium nor potassium values fall outside the ± 2 standard deviations from the mean.

Mineral Resource Estimates

The Company has not previously disclosed a mineral resource estimate in accordance with S-K 1300. The following is a brief discussion of the material assumptions and criteria underlying the mineral resource estimate. Please see Section 11 of the Pastos Grandes TRS for more detail.

The qualified person of the Pastos Grandes TRS is of the opinion that the quantification of parameters used in the resource estimate, including lithium concentrations, drainable porosity and aquifer geometry, is appropriate (and follow S-K 1300 standards) to support the Mineral Resource estimate for the Pastos Grandes Project described herein.

A Mineral Resource estimate for the Pastos Grandes Project is summarized in the tables below.

The Mineral Resource estimate was determined by defining the aquifer geometry, the drainable porosity or specific yield ("Sy") of the hydrogeological units in the Salar, and the concentration of the elements of economic interest, mainly lithium and potassium. Mineral Resources were defined as the product of the first three parameters. The model resource estimate is limited to the PGSALAC mining concessions in Salar de Pastos Grandes and do not include the AMSA properties The resource model domain is constrained by the following factors:

The upper boundary of the model is determined by the highest elevation samples within the dataset and, or the phreatic brine level.

The lateral extent of the resource model covers an area of 56 km2, confined within the boundaries of the PGSALAC mining claims in the Salar. Additionally, the extent is restricted by the contact between the Quaternary basin and the underlying basement rock.

The lower boundary of the model domain is set to coincide with the basement from the geological model or the total depth of 635 m when the basement is not present.

The specific yield values used to develop the resources are based on results of the logging and hydrogeological interpretation of chip samples and recovered core from the drilling programs, results of drainable porosity analyses carried out on 76 undisturbed core samples by Corelabs, GeoSystems Analysis, Daniel B Stephens & Associates. Boreholes within the measured and indicated resource areas are appropriately spaced at a borehole density of one bore per 4 km2. The table below shows the drainable porosity values assigned to the different geological units for the resource model. The distributions of lithium and potassium concentrations in the model domain are based on a total of 501 brine analyses (not including QA/QC analyses).

The Mineral Resource estimation for the Pastos Grandes Project was developed using the Stanford Geostatistical Modelling Software (SGeMS) and the geological model as a reliable representation of the local lithology. The author of the Pastos Grandes TRS was closely involved with the block model development; all results have been reviewed and checked at various stages and are believed to be valid and appropriate for these resource estimates. The table below shows the mineral resource estimate for lithium and potassium for the PGSA mining claims of the Pastos Grandes Project.

Notes to the resource estimate:

1. S-K 1300 definitions were followed for Mineral Resources.

2. The Qualified Person for this Mineral Resource estimate is Frederik Reidel, CPG

3. No Mineral Reserves have been estimated for this updated Mineral Resource Estimate.

4. The Mineral Resource Estimate is reported as lithium contained in brine in-situ.

5. The Mineral Resource Estimate is not a Mineral Reserve Estimate and does not have demonstrated economic viability.  There is no certainty that all or any part of the Mineral Resources will be converted to Mineral Reserves. Inferred Resources have great uncertainty as to their existence and whether they can be mined economically.

6. A cut-off grade of 200 mg/l has been applied to the M+I+I resources estimates.

The cutoff grade is based on the various inputs and the formula blow:

Cutoff Grade

	(Total Capital Expenditure+Total Operating Expense)
=	Total Brine Extracted
	(Recovery*Conversion from Li to Li2CO3*Projected LCE Price*(1 - Export Duties)*(1 - Royalties))

 

---

Where:

Total Capital Expenditure= USS 1,781 million
Total Operating Expenditure = USS 6,020 million
Cost of Capital = USS 178 million (10 percent of Total Capital)
Total Brine Extracted = 628 Mm3
Conversion from Li to Li2CO3= 5.323
Projected LCE Price = USS 20,00 per metric ton of LCE
Export Duties =4.5%
Royalties= 3.0%

Calculated Recovery= 65%

Resulting in a calculated cut-off grade of 200 mg/l.

Factors that may affect the Brine Resource estimate include: locations of aquifer boundaries; lateral continuity of key aquifer zones; presence of fresh and brackish water which have the potential to dilute the brine in the wellfield area; the uniformity of aquifer parameters within specific aquifer units; commodity price assumptions; changes to hydrogeological, metallurgical recovery, and extraction assumptions; density assignments; and input factors used to assess reasonable prospects for eventual economic extraction. Currently, Mr. F. Reidel (the QP), does not know any environmental, legal, title, taxation, socio-economic, marketing, political, or other factors that would materially affect the current Resource estimate.

7. Numbers may not add due to rounding averaging.

8. The effective date is December 31, 2024.

Mineral Resource Estimate Comparison Between December 31, 2023 and 2024

For the year ended December 31, 2023, the Company was not subject to S-K 1300, and reported its mineral resources in accordance with NI 43-101.  For ease of comparison, the estimates for the project are shown on a 100% basis.  The Company's attributable interest is 85.1% of the tonnage stated in the tables.

Mineral Resources

The table below sets forth the comparison of the Mineral Resources as set forth in the Company's annual report on Form 40-F for the year ended December 31, 2023, and as set forth in the Company's annual report on Form 20-F for the year ended December 31, 2024. The decreases in the mineral resources are primarily due to the fact that under S-K 1300, mineral resources are estimated exclusive of mineral reserves.

Mining Operations Based on the results of the pumping tests carried out for the Pastos Grandes Project (as described above) brine abstraction from the Salar de Pastos Grandes will take place by installing and operating a conventional production wellfield.  The production process starts when brine is extracted from the aquifer beneath the Pastos Grandes Salar, it is then pumped from each well to pre-concentration ponds located near the active wells. From these latter ponds brine is pumped to the remaining evaporation ponds and, once concentrated and partially purified, it is sent to the lithium carbonate plant.

Results of the pumping tests for the project indicate that pumping rates of individual brine production wells will be an average of 20 l/s for each well. Therefore, it is planned that an average of 30 production wells will be operative at various flow rates optimized to extract brine from areas of higher lithium grades and higher transmissivity in order to meet the required brine feed rate of 540 l/s, as an average (varying from 480 l/s in Stage 1 to 600 l/s in Stage 2). Seasonal fluctuations in the evaporation rate dictate that the required brine feed rate which will decrease during the winter months and will increase during the summer months. Well completion depths will vary and are still being studied. Brine production wells will be completed with 12-inch diameter stainless steel production casing and equipped with 380 V submersible pumping equipment. Permanent power will be delivered to the wellfield area through a mid-range power line.

The overall wellfield configuration is in process of being defined. Each well is to be completed with a submersible electric pump. These pumps can be powered initially by an adjacent dual-fuel (gas or diesel) generator, and eventually by an electrical distribution system from the centralized power house.

Brine discharged from each wellhead will be piped through 8-inch diameter HDPE feeder pipelines to two central collection/transfer ponds that are located near the well field. Collected brine will then be pumped at a diurnal, seasonal, and at an adjusted, as needed, rate to the evaporation ponds located mainly on the flat Salar surface.

Planned Exploration and Development

The following technical work may further advance the Pastos Grandes Project towards construction and into production.

● Incorporate the lithium resources hosted on the Arena Minerals properties into the resource estimate for the Pastos Grandes Project so that these resources can be properly incorporated in the numerical groundwater flow and transport modeling for final brine production wellfield design, evaluation of potential environmental constraints, and the estimation of updated reserves.

● Carry out a 30-day pumping test on Arena Minerals production well PW-1 to characterize the southern extent of the lower brine aquifer.

● Drill three deep core holes into the lower brine aquifer to improve the confidence level of geological and drainable porosity parameters in the central clastics and basal gravel /breccia units. These holes should be completed as deep monitoring wells for additional observations point during the additional pumping tests recommended.

● Carry out 30-day pumping tests in existing brine production wells PGPW18-15 and PGPW18-17 with water level monitoring in the above-mentioned new observations points.

● Carry out 7-day pumping test on water production wells PGMW19-2 and PGPW19-3; along with additional groundwater exploration work to secure future water supply requirements from freshwater resources within the Pastos Grandes and Sijes basins.

● Numerical modelling should be resumed with the Arena Minerals developed 3D FEFLOW groundwater flow and transport model for the basin to carry out predictive simulations for the design and layout of the future brine production wellfield, evaluation of potential environmental effects, and the preparation of updated lithium reserves for the Pastos Grandes Project.

● Based on the results of the predictive model simulations, install three additional brine production wells in the lower brine aquifer.

● Implement systematic hydro(geo)logical monitoring programs of surface water and groundwater features to reinforce the baseline characterization of the Pastos Grandes basin. Continue with the surveys and studies to improve the quantification of the water balance components of the basin.

---

● Drill 7-10 deep exploration core holes aimed at increasing the lithium resource base of the Pastos Grandes Project.

● Drill four industrial water exploration wells to evaluate the resources and optimize the production strategy, including Arena Minerals' blocks to the North and East of the basin.

The estimated budget to complete and implement the above recommendations are shown in the table below:

Item	Cost
Pumping tests on existing wells (3)	US$360,000
Infill resource drilling (3 holes)	US$6,300,000
Resource exploration drilling (7 holes)	US$16,800,000
Production drilling (8 holes)	US$32,800,000
Hydrogeological monitoring programs	US$775,000

Internal Controls Over Mineral Resource and Reserve Estimates.

The Company has internal controls for reviewing and documenting the information supporting the Mineral Resource and Mineral Reserve estimates, describing the methods used, and ensuring the validity of the estimates. Information that is used to compile mineral resources and reserves is prepared and certified by appropriately qualified persons at the project sites and is subject to our internal review process which includes review by appropriate management. An independent Qualified Person is contracted by the Company to certify resources and reserves estimates according to S-K 1300 standards.

Indebtedness of Directors and Executive Officers

None of the current or former directors, executive officers, employees of the Company or its subsidiaries or their respective associates or affiliates, are or have been indebted to the Company or its subsidiaries since the beginning of the last completed financial year of the Company.

Executive Compensation

As a result of the Separation Transaction, our executive management was reconstituted in October 2023 to be comprised, among others, of John Kanellitsas, Executive Chair, President and Interim CEO, and Alex Shulga, Vice President and CFO. On March 18, 2024, Sam Pigott joined the Company as President and CEO. This section includes historical information with respect to executive compensation prior to the Separation Transaction as well as information regarding our practices post-Separation Transaction.

The Governance, Nomination, Compensation and Leadership Committee, on behalf of the Board, is responsible for overseeing the Company's executive compensation program.

In 2023, the Board adopted an Incentive Compensation Recovery Policy, which provides for the recovery of erroneously awarded incentive compensation from covered executives in the event that the Company is required to prepare an accounting restatement due to material non-compliance of the Company with any financial reporting requirements under United States securities laws and NYSE requirements. A copy of the Incentive Compensation Recovery Policy can be found on the Company's website at www.lithium-argentina.com.

Executive Compensation Philosophy

The Company's goal is to offer a compensation program that is competitive within the median range of a select group of industry peers for executive compensation comparison purposes, with the overall focus of our program being to offer competitive base compensation to executives and pay for strong performance through an annual performance management program, with a particular emphasis on compensating executives through equity securities to better align executives' financial interests with the interests of shareholders. The goals of our executive compensation program are:

• To attract, motivate and retain high performing executives through market competitive base salaries and employee benefits, which are offered throughout the organization;
   
• To pay for performance of our executives through our performance management program, which includes performance reviews and awards based on a combination of individual performance and the attainment of corporate and individual goals and objective each year, thereby furthering the interests of the Company, and adding an at-risk component to executive compensation;

---

• To recognize the contribution of our executives to our profitability and long-term growth through the award of short-term and long-term equity incentives based on executive and corporate performance; and
   
• To align the financial interests of executives with the interests of our shareholders and the Company's overall performance through the award of equity incentives that expose executives to the risks and rewards of ownership of our Company's equity securities.

As an operational stage lithium mining and processing company that recently commenced production of battery grade lithium products, we are dependent on individuals with specialized skills and knowledge related to mining exploration, development and operations, capital projects management, chemical processing for  lithium products, corporate finance, legal, human resources, and other areas of business or management expertise. We operate in regions where competition for talent is increasingly strong, the number of opportunities for job seekers is growing and where it is increasingly important for companies to have competitive compensation programs and practices in place to retain and attract talent.

For the year ended December 31, 2024, our compensation program  included the following components: base salary, short-term incentive ("STI") annual performance award generally payable 100% in short-term vesting RSUs, long-term incentive ("LTI") performance award payable 100% in  three year vesting RSUs , and employee benefits such as retirement savings plan contributions, extended health, dental, life and disability insurance, and a health and wellness benefit to encourage a healthy lifestyle for our executives and staff generally.

2024 was another transformational year for the Company with the achievement of commercial production at Cauchari-Olaroz, the Pastos Grandes Transaction, the successful advancement of the Company following the Separation Transaction and the strategic continuation of the Company to Switzerland, which are accomplishments for which our executives deployed significant time and efforts. Management and the Governance, Nomination, Compensation and Leadership Committee worked with Lane Caputo, an independent compensation advisor to the Company, to evaluate and refine a new executive compensation program for 2024 and beyond in line with the new attributes specific to the Company post-Separation Transaction.

Compensation Governance

Compensation matters are overseen by the Governance, Nomination, Compensation and Leadership Committee. All members of the committee are current or former executive officers/directors of public or private companies, providing them with an understanding of executive compensation policies and practices, along with practical experience as to the workings of such programs and policies. The committee also has the ability to engage external advisors to support committee members in fulfilling the mandate of the committee.

Compensation Advisor and Peer Group Benchmarking Review

To offer market competitive levels of compensation, we previously engaged Willis Towers Watson ("WTW") in 2017 to provide independent compensation advisory services to the Governance, Nomination, Compensation and Leadership Committee and management on our compensation program. The benchmark compensation review completed by WTW, management and the Governance, Nomination, Compensation and Leadership Committee involved the development of a compensation peer group comprised of public lithium mining companies, other diversified mining companies, and lithium and other specialty chemical producers in Canada, the United States and Australia who publicly disclose their compensation practices. After developing the compensation peer group, a comparison of target total direct compensation of our executives with that of the peer group was assessed, together with other industry compensation reports. From there increases to executive compensation were determined, taking effect in 2023.

Following the Separation Transaction, the Company engaged Lane Caputo to assist with developing a new fee schedule for independent directors based on a benchmarking exercise to a revised peer group.Lane Caputo  also assisted in developing a new executive compensation program for 2024 in line with the new attributes specific to the Company post-Separation Transaction as described below.

There is no requirement for the Governance, Nomination, Compensation and Leadership Committee to pre-approve other services the independent compensation advisor or any of its affiliates provides to the Company at the request of management.

Fees we paid to our independent compensation advisors, Lane Caputo for the 2024 fiscal year and WTW  for the 2023 fiscal year are set out below.

Compensation Advisory Fees	For the years ended December 31,
	2024 (US$)	2023 (US$)
Executive compensation related-fees	$55,606	$20,353
All other fees	$3,381	$20,666
Total fees	$58,987	$41,019

Performance Evaluation and Compensation Process

The Company follows an internal compensation planning process. Parties participating in the process include management, the Governance, Nomination, Compensation and Leadership Committee and an independent compensation advisor as engaged from time to time. Executive compensation decisions and recommendations by management are made by our CEO and Executive Chair (the "Management Compensation Committee"). The Management Compensation Committee evaluates annual performance reviews and make recommendations to the Governance, Nomination, Compensation and Leadership Committee on performance awards for executives other than the CEO and Executive Chair. The Governance, Nomination, Compensation and Leadership Committee then reviews the recommendations in light of the Company's compensation and retention strategy to ensure proposed awards are aligned with the overall design of the compensation program and the Company's business needs, and seeks input from the independent compensation consultant as needed. Annual performance evaluations for the CEO and Executive Chair are assessed by the Governance, Nomination, Compensation and Leadership Committee, which as a committee determines performance awards for these executives. Once the Governance, Nomination, Compensation and Leadership Committee and the Management Compensation Committee have agreed on final performance awards and any changes to executive compensation, these are submitted by the Governance, Nomination, Compensation and Leadership Committee with a committee recommendation for Board consideration. Board approval is required for items such as equity compensation grants, including STI and LTI equity awards, and salary changes for the CEO, Executive Chair and other senior officers of the Company.

The Company historically engaged an independent compensation consultant to conduct a bi-annual review of executive compensation, benchmarked to compensation of a selected peer group. This process is overseen by the Governance, Nomination, Compensation and Leadership Committee, which receives recommendations from the consultant and determines if any changes are needed to our executive compensation program and levels of compensation. In non-review years, the Management Compensation Committee will consider cost-of-living adjustments to base salary for executives along with other staff and provide a recommendation for consideration by the Governance, Nomination, Compensation and Leadership Committee based on changes to indices measuring inflationary conditions in the regions where our executives and staff work.

Compensation Benchmarking

Benchmarking of executive compensation compares actual and target compensation against a peer group to benchmark for the position, organizational role and scope of responsibility. The peer group for 2024 was recommended by Lane Caputo and selected based on the criteria set out below .

Criteria for Selection as Compensation Peers in 2024
Industry	Companies operating in industries that will overlap with the Company's business targeting battery-grade lithium products, being the diversified metals and mining industry (including lithium)
Geographic Location	Publicly traded companies headquartered in North America were selected as many of the Company's executives are based there and the Company is listed on the NYSE and TSX, along with Australia where many global, public lithium companies are headquartered
Size	Comparable size to the Company based on market capitalization, enterprise value and projected revenues, with the Company falling near the median point compared to peers

Compensation Peer Group

The criteria set out above were applied to develop the following compensation peer group of 15 companies, recommended by Lane Caputo the Governance, Nomination, Compensation and Leadership Committee, and approved by the Board.

Compensation Peer Group

Elements of Executive Compensation

The Company generally utilizes a combination of both fixed and variable compensation to motivate executives to achieve overall corporate goals. The Board, acting on the recommendation of the Governance, Nomination, Compensation and Leadership Committee, has implemented a compensation structure intended to align the interests of the executive officers with those of the Shareholders. The elements of the Company's historical executive compensation program are summarized in the table below.

Compensation Elements	Features	Objectives
Base Salary	Evaluated annually, alternating with a bi-annual benchmarking executive compensation review, and in non-benchmarking years a bi-annual cost-of-living adjustment.	Fixed compensation, recognizing individual experience, performance and responsibilities. Targeting salary to the median range of compensation peers promotes retention of talented individuals as executive officers, and facilitates recruitment of new talent in a competitive job market landscape.
STI Awards	RSUs with one-year vesting conditions. STI award = Base Salary x STI Target % x (Corporate Performance based on % weight by position + Individual Performance based on % weight by position).	Rewards performance by executives for achieving annual individual goals and corporate strategic goals. Designed to motivate executives, recognize annual contributions by individuals, and align executive performance with corporate strategic priorities.
LTI Awards	RSUs with three-year vesting conditions. LTI = Base Salary x LTI retention factor.	Promotes longer-term retention and aligns long-term interests of our executives with those of shareholders. At risk award that links long-term equity plan payouts to relative total share price performance over a three-year period Rewards executives for industry out-performance.
Retirement Savings Plan Contributions	Annual contribution matching by the Company to a retirement savings plan, up to 3% of base salary, subject to a contribution ceiling established annually (2024 - US$23,000 for ages below 50; US$30,500 for ages 50 and over).	Market competitive benefit. Encourages retirement savings by our executives.
Health, Wellness and Other Benefits	Health, dental, life, critical illness and disability insurance. Health and wellness spending account.	Market competitive benefits. Encourages and supports health and wellness for our executives.

The Governance, Nomination, Compensation and Leadership Committee reviews each element of

compensation for market competitiveness, and it may weigh a particular element more heavily based on

the respective executive's role and responsibilities within the Company. The committee's focus is on remaining competitive in the market with respect to the Company's total compensation program, in addition to certain components of executive compensation such as base salary and our performance-based compensation program.

---

Base Salary

Base salaries are set with the goal of being competitive with corporations of a comparable size and stage of development, thereby enabling the Company to compete for and retain executive officers critical to the Company's long-term success. The Governance, Nomination, Compensation and Leadership Committee and the Board approve the salary ranges for executives based on the peer group compensation  benchmarking review generally occurring bi-annually. Salary determinations for executives by the committee and management are made with consideration of the Company's financial resources and the following criteria, among others:

• The particular responsibilities related to the position;
• Salaries paid by comparable businesses and factoring in market conditions for talent;
• The experience level of the executive; and
• The executive's overall performance or expected performance (in the case of a newly hired executive).

An assessment of these criteria is made by the Governance, Nomination, Compensation and Leadership Committee for the CEO and Executive Chair. For other Named Executives excluding the CEO and Executive Chair, the assessment is made by management, and a recommendation is made to the committee for feedback and recommendation to the Board. Final recommendations are then made to the Board to approve base salary adjustments.

Short-Term Incentive Compensation

The Company awards annual STI compensation to executives based on the achievement of corporate and individual goals for the year. STI awards have the objective of motivating executives to achieve performance objectives that are aligned with the overall strategic objectives of the Company during the period.

A target range for an STI award as a percentage of salary is generally set for each executive position. Actual bonuses awarded are subject to a multiplier depending on actual performance for the year. STI compensation is discretionary and generally consists of a grant of RSUs. RSUs are awarded under the Incentive Plan.

Management determines recommendations for STI awards based on the outcome of annual performance reviews for each executive other than the CEO and Executive Chair. New grants take into consideration corporate and individual performance for the annual period and generally do not factor in prior grants made to an individual except if we are nearing the maximum number of Shares issuable under the Incentive Plan. Recommendations are submitted by management to the Governance, Nomination, Compensation and Leadership Committee for consideration and approval. The Governance, Nomination, Compensation and Leadership Committee determines STI awards for the CEO and Executive Chair, while all other awards are recommended by management with the Governance, Nomination, Compensation and Leadership Committee providing feedback as needed on the recommended amount of such awards. All grants for equity STI awards are approved by the Board.

During the year ended December 31, 2024, the Company utilized a corporate performance scorecard with objectives and various range weights based on position level as well as performance achieving individual goals for the year. Corporate goals and objectives were then cascaded down throughout the organization, after being approved by the Governance, Nomination, Compensation and Leadership Committee. These goals and objectives are generally reflected in five broad categories as set out in the table below. Each category was assigned a particular weighting, with performance weighted on a scale of 1 to 5.

---

Management recommended, and the Governance, Nomination, Compensation and Leadership Committee accepted, a payout of 150% for overall corporate performance.

The individual performance and weighting of individual performance in respect of each named executive is set out in the table below.

Named Executive Officer	Individual Weighting	Individual Rating	Payout
John Kanellitsas, Executive Chair	0%	4	150%
Sam Pigott, President and Chief Executive Officer	0%	4	150%
Alec Meikle, Executive Vice President, Corporate Development	40%	5	200%
Alex Shulga, Vice President and Chief Financial Officer	35%	3.25	130%
Mariano Chiappori , Vice President and Chief Operating Officer	40%	3.25	130%

For 2024, the minimum, the STI target and maximum payout opportunity for each named executive is set out below, as a percentage of base salary. The STI award may be revised above or below the target set for any of our senior management, including named executives, in the Board's discretion on recommendation from the Governance, Nomination, Compensation and Leadership Committee within the minimum and maximum ranges provided in the table.

---

* Sam Pigott's STI was pro rated to reflect his employment with the Company starting on March 18, 2024 and Alec Meikle's STI was pro rated to reflect his employment with the Company starting on July 31, 2024.

Long-Term Incentive Compensation

LTI compensation is another key component of the Company's executive compensation program. LTI compensation is awarded to motivate performance by executives and promote retention with a strong focus on long-term alignment of executives' interests with those of shareholders. Executives are also provided with an opportunity to share in the rewards of the Company's performance, together with the associated risks of ownership of the Company's securities.

For the year ended December 31, 2024, the Company awarded RSUs to executives as LTI awards under the Incentive Plan. The RSUs have a three-year vesting period. The Company has the discretion to award Options under the Incentive Plan, however, did not grant any Options as part of LTI.

LTI awards for the CEO and Executive Chair are determined by the Governance, Nomination, Compensation and Leadership Committee, and for other executives are determined by the CEO and reviewed by the Management Compensation Committee prior to their recommendation to the Governance, Nomination, Compensation and Leadership Committee, with all awards being determined based on a combination of individual performance and consideration of long-term retention. The Governance, Nomination, Compensation and Leadership Committee then makes a recommendation for Board approval of all LTI awards to be granted as equity compensation.

The LTI awarded to each named executive for 2024 is set out below, as a percentage of base salary. Similar to STI awards, a LTI award may be revised for any of our senior management, including named executives, in the Board's discretion on recommendation from the Governance, Nomination, Compensation and Leadership Committee.

---

Benefits

We provide a benefits program, including health, dental, life, critical illness and disability insurance,

employee and family assistance program, and a health and wellness spending account to encourage a healthy lifestyle for our employees, including Named Executives.

Management Risks

The Governance, Nomination, Compensation and Leadership Committee and the Board periodically assess the implications of the risks associated with the Company's compensation policies and practices. The committee maintains sufficient discretion and flexibility in implementing compensation decisions such that unintended consequences in remuneration can be minimized, while still being responsive to market influences in a competitive environment. Through the Governance, Nomination, Compensation and Leadership Committee Charter, the Governance, Nomination, Compensation and Leadership Committee has sole authority to retain consultants to assist it in the evaluation of compensation of senior management and directors. The Company has policies in place to mitigate compensation policies and practices that could encourage Named Executives to take inappropriate and excessive risk. All material contracts and agreements require Board approval. The Board also approves annual and capital budgets.

The Company has a Securities Trading Policy, which applies to employees, officers, directors and consultants ("Covered Persons") of the Company, its subsidiaries and joint venture interests, and also extends to any trading by trusts and holding companies controlled by Covered Persons. The Company also expects Covered Persons will ensure compliance by family and other members of their household.

The Securities Trading Policy stipulates that the Company and its Covered Persons are subject to restrictions against trading in securities of the Company while in possession of material information that has not been publicly disclosed. The Securities Trading Policy also prohibits hedging and derivatives trading, engaging in short sales and trading on margin or pledging the Company's securities. The Securities Trading Policy is posted on our website.

Performance Graph

The graph and table on the following page compares the cumulative shareholder return on a C$100 investment in Shares to a similar investment in companies comprising the S&P/TSX Composite Total Return Index, including dividend reinvestment, for the period from January 1, 2019 to December 31, 2024:

Notes:

(1) The cumulative return of the Company's Shares is based on the closing prices of the Shares on the TSX on December 31, 2019, 2020, 2021, 2022 and 2023 or, if there was no trading on such date, the closing price on the last trading day prior to such date. It has been assumed that upon completion of the Separation Transaction, Lithium Americas Corp. common shares received were sold on October 4, 2023, and that the proceeds were reinvested in the Shares.

(2) The S&P/TSX Composite Total Return Index is a total return index (C$), the calculation of which includes dividends and distributions reinvested.

As shown in the graph above, during the fiscal year ended December 31, 2024, the Company's Share price declined relative to the S&P/TSX Composite Total Return Index for the 2024 calendar year, however, has increased relative to the S&P/TSX Composite Total Return Index over the 5-year timeframe. The Company believes that the share price performance has been impacted primarily by declining lithium commodity prices and macroeconomic factors affecting electric vehicle sales, such as high interest rates and high inflation. Over the same period, the price of lithium declined by approximately 40%.

The trend in overall compensation paid to the Company's executive officers over this period has not directly tracked the performance of the market price of the Shares or the S&P/TSX Composite Total Return Index, however, as the majority of executive compensation is the form of equity-based compensation, executive compensation is substantially aligned with market performance. The unique circumstances of the Company in 2023 required a major reconfiguration of our management team and significant efforts of our management which was reflected in our compensation profile, with the development and commencement of production at the Cauchari-Olaroz, the successful acquisition of Arena Minerals, the completion of the Separation Transaction and the financing with GM for the development of the Thacker Pass project. Given the Company's stage of development, the Company's Share price can be volatile and is currently not a significant factor in cash compensation considerations. The value of LTI compensation in the form of preferred share units ("PSUs") and RSUs is influenced by our Share price performance.

 Notes:

(1) Financial years ended December 31, 2024, December 31, 2023 and December 31, 2022.

(2) Share-based awards consist of RSUs granted under the Incentive Plan. The amount of equity-settled payment arrangements is based on the estimated fair value at the grant date. For RSUs, the fair value is based on the five-day VWAP of US$2.78 for 2023 RSUs (US$5.40 for 2023 RSUs and US$25.27 for 2022 RSUs) calculated as of the day prior to the grant date.

(3) Non-Equity Incentive Plan Compensation represents the cash performance bonuses awarded in each year disclosed in the table.

(4) The fair value of Options granted was estimated on the date of grant using the Black Scholes Option Pricing Model. These Options are exercisable at a prices of US$5.18 until April 2, 2031. The key assumptions used under the Black Scholes Option Pricing Model; that were used for the Option awards in the table above were: risk-free rate 4.27%; expected life 7 years; annualized volatility 73.66%; expected dividend rate nil. The Company chose to use the Black Scholes Option Pricing Model as the basis for calculating fair value of the Options granted as this methodology is commonly accepted by issuers. The values presented are consistent with the accounting values used in the Company's audited financial statements.

(5) The fair value of Options granted was estimated on the date of grant using the Black Scholes Option Pricing Model. These Options are exercisable at a prices of US$3.85 until June 20, 2031. The key assumptions used under the Black Scholes Option Pricing Model; that were used for the Option awards in the table above were: risk-free rate 4.27%; expected life 7 years; annualized volatility 73.66%; expected dividend rate nil. The Company chose to use the Black Scholes Option Pricing Model as the basis for calculating fair value of the Options granted as this methodology is commonly accepted by issuers. The values presented are consistent with the accounting values used in the Company's audited financial statements.

(6) For RSUs, the fair value is based on the five-day VWAP of US$3.85 calculated as of the day prior to the grant date.

(7) Appointed Chief Executive Officer effective from March 19, 2024

(8) Equity-based compensation consist of RSUs and Stock Options one time sign-on bonus granted under employment contracts.

(9) Appointed Executive Vice President, Corporate Development on July 31, 2024.

(10) Includes contractor fees before appointed as Executive Vice President, Corporate Development.

(11) 2023 compensations are adjusted to include equity-based compensation awarded in June 2024 for 2023 performance.

Fair Value of Stock Option Grants, RSUs, PSUs and DSUs

Under the Plan, which was implemented in March 2016, the Company may grant RSUs, PSUs, DSUs and Options to directors, officers, employees and service providers. The cost of equity-settled payment arrangements is recorded based on the estimated fair value at the grant date and charged to

earnings over the vesting period.

Following a 2025 review of the Company's Board compensation and LTI compensation for executives by Lane Caputo, the Board determined that equity incentives for executive officers should be in the form of RSUs and DSUs to directors, with no further Option awards. The fair value of Options granted by the Company is treated as compensation costs in accordance with International Financial Reporting Standards 2, Share-based Payment.

Each tranche of an equity award is considered to be a separate award, with its own vesting period and

grant date fair value.

Employment Agreements

The following descriptions of employment agreements with the Company's Named Executives are effective as of December 31, 2024. On January 23, 2025, in connection with the Company's continuation to Switzerland, the Company entered into new employment agreements (the "2025 Employment Agreements" and each a "2025 Employment Agreement") with John Kanellitsas, Executive Chair, Sam Pigott, President & Chief Executive Officer, Alec Meikle, Executive Vice President, Corporate Development, and Alex Shulga, Vice President and Chief Financial Officer. The 2025 Employment Agreements reflect certain changes required by Swiss law that, among other things, removed payments on termination and on termination after a "Change of Control".

John Kanellitsas, Executive Chair

As at December 31, 2024, Mr. Kanellitsas was paid a base annual salary of US$420,000, and was eligible to receive short-term incentive compensation at a target rate of 75% of base salary (the "Kanellitsas STI Bonus") and long-term incentive compensation at a target rate of 75% of base salary.

On termination of employment without "Cause", because of "Disability" or for "Good Reason", each as defined in Mr. Kanellitsas' employment agreement, Mr. Kanellitsas will receive the following severance package: (a) 18 months (the "Kanellitsas Severance Period") of base salary; (b) 1.5 times Kanellitsas STI Bonus he received for the year prior to the year in which his employment terminates; (c) accelerated vesting of any equity Awards scheduled to vest during the Kanellitsas Severance Period; and (d) continuation of benefits coverage during the Kanellitsas Severance Period or reimbursement for replacement coverage (the "Kanellitsas Severance Package").

defined in Mr. Pigott's employment agreement, Mr. Pigott will receive the following severance package: (a) 12 months (the "Pigott Severance Period") of base salary; (b) the Pigott STI Bonus he would have earned through the Pigott Severance Period based on the Pigott STI Bonus for the year prior to the year in which his employment terminates; and (c) continuation of benefits coverage during the Pigott Severance Period or reimbursement for replacement coverage (the "Pigott Severance Package"). Notwithstanding the foregoing, the Severance Period shall increase by two months on each anniversary of the effective date of the employment agreement, up to a maximum Severance Period of eighteen (18) months.

Notes:

(1) The entitlement of the named executives to payment upon a change of control is not necessarily in substitution for, and may be in addition to, amounts payable to such named executives upon termination by the Company.

(2) Amounts above include, among other things, amounts payable in lieu of bonuses that would have been earned during the applicable severance period.

(3) For the equity component, the amount represents the realizable value as of December 31, 2024 of Options, RSUs and PSUs which are subject to accelerated vesting. The value of unexercised "in-the-money options" is calculated on the basis of the difference between the closing price of the Shares on the NYSE on December 31, 2024 of US$2.62 and the exercise price of the Options. The value of accelerated RSUs and PSUs is calculated on the basis of the closing price of the Shares on the NYSE on December 31, 2024 of US$2.62.

(4) As of January 23, 2025, the Salary and Bonus figures for Mr. Kanellitsas, Mr. Pigott, Mr. Meikle and Mr. Shulga would be reduced to 0.

Management Contracts

No management functions of the Company or its subsidiaries are to any substantial degree performed by a person or company other than the directors and officers of the Company or its subsidiaries.

Annual Burn Rate

The annual burn rate of the Incentive Plan for the last three financial years is set out below. This figure is calculated by dividing (i) the number of Awards granted under the Incentive Plan during the applicable financial year, by (ii) the weighted average number of Shares outstanding for the applicable financial year. "Awards" for the purposes of this calculation means all RSUs, PSUs, DSUs and Options.

This calculation does not reflect the new replacement incentive securities issued in exchange for old incentive securities as part of the Separation Transaction.

Financial Year ended December 31	Number of Awards awarded under the Incentive Plan (a)	Weighted average number of Shares outstanding during the applicable financial year (b)	Annual burn rate ((a)/(b)) (c)
2024	3,209,025	161,338,014	1.99%
2023 (Post-Separation Transaction)	2,943,500	155,331,000	1.9%
2023 (Pre-Separation Transaction)	598,408	153,129,000	0.39%
2022	236,195	133,709,000	0.18%

Securities Authorized For Issuance Under Equity Compensation Plans

Overview

Below is a summary of the material terms of the Second Amended and Restated Equity Incentive Plan (the "Incentive Plan") as last amended and approved by the Board on January 23, 2025.

The Second Amended and Restated Equity Incentive Plan is our only equity incentive plan and governs all equity incentives awarded by LAR, including Options, DSUs, and Restricted Share Rights (time based or in the form of PSUs). We are permitted to issue an aggregate of 8% of the Shares based on the current number of Shares outstanding.

Summary of the Second Amended and Restated Equity Incentive Plan

SECOND AMENDED AND RESTATED EQUITY INCENTIVE PLAN SUMMARY

Plan Type and Shares Available for Award Grants

Subject to the conditional capital of the Company for equity incentive plans under the Company's Articles of Association, our plan is an 8% "rolling" equity compensation plan, with maximum number of equity awards disclosed in the next table, pursuant to TSX and NYSE requirements. Any increase to the percentage number of awards must be cleared with TSX and NYSE and would generally require shareholder approval. For greater certainty, any increase in the issued and outstanding Shares will result in an increase in the available number of Shares issuable under the Second Amended and Restated Equity Incentive Plan, and the exercise or settlement of awards under the Second Amended and Restated Equity Incentive Plan will make new grants available under the Second Amended and Restated Equity Incentive Plan.

C. Board Practices

About the Board

The Board consists of eight directors whose terms expire annually. John Kanellitsas, George Ireland and Franco Mignacco have served as directors since 2015 and Diego Lopez Casanello, Robert Doyle and Calum Morrison have served as directors since 2023. On March 19, 2024, Sam Pigott and Monica Moretto were appointed to the Board. Each director nominee elected will hold office until their successor is elected at the next annual meeting of Shareholders, or any postponement(s) or adjournment(s) thereof, or until their successor is otherwise elected or appointed. There are no directors' service contracts with the Company or any of its subsidiaries providing for benefits upon termination of employment.

---

Role and Mandate

The Board has overall responsibility for corporate governance matters by virtue of its responsibility for:

• developing and approving corporate policies and guidelines;
• assisting in the definition of corporate objectives and assessing corporate strategies and key plans;
• overseeing material risks of the Company and its business;
• overseeing the integrity of our internal financial controls and management information systems;
• evaluating the Company's performance and the performance of the Board, its committees and individual directors; and
• appointing executive officers and, together with the relevant committee, reviewing their performance.

The Board has adopted a Corporate Governance Framework where the Board has outlined its responsibilities in a board mandate. The board mandate and structural parameters of the Board is available in Lithium Argentina's Corporate Governance Framework on our website (www.lithium-argentina.com).

Independence

The Board currently has eight (8) members of whom five (5) qualify as independent directors, being a majority, under the Corporate Governance Disclosure Rules. This includes our Lead Independent Director, George Ireland. Except for our Sustainable Development Committee, our committees are all comprised entirely of independent directors, including the Chairs of each committee. The independent directors are: George Ireland, Diego Lopez Casanello, Robert Doyle, Calum Morrison and Monica Moretto.

The non-independent directors of the Company are Sam Pigott, who is the President and CEO of the Company; John Kanellitsas, who is the Executive Chair; and Franco Mignacco, who was the President of Exar, which is a significant equity investee of the Company, and is now the Chair of the Shareholder Committee of Exar.

Generally independence of a director means that the individual is not an employee or member of management of the company or any subsidiary, receives no compensation from the company or a subsidiary except compensation for serving as a director on the Board, and generally the individual has no conflicts of interest or other ties to management, the company or a subsidiary that would lead to a determination that the individual is unable to exercise judgement independent of management. These same considerations extend to immediate family members of the individual.

Directors on our Board with an interest in a material transaction or agreement are required to declare their interest and abstain from voting on the transaction or agreement at issue. The Board also forms special committees as needed, comprised of only independent directors, to evaluate proposed related party transactions and ensure that independent judgement is used to evaluate the transaction, free of any potential or actual conflict of interest, or for other purposes as needed and determined by the Board in its sole discretion.

Our Shares are dual-listed in Canada and the U.S. NYSE requirements and U.S. securities laws set out different requirements for determining director independence than TSX requirements and securities laws in Canada. As a "foreign private issuer" under U.S. securities laws, the Company is permitted to follow Swiss requirements (as our home country) instead of certain NYSE corporate governance standards, including director independence but this does not apply to audit committee independence requirements under U.S. securities laws. The three (3) members of our Audit and Risk Committee satisfy the independence requirements of Rule 10A-3 under the Exchange Act.

Role of the Chair and the Independent Lead Director

The Board Chair leads the Board and is responsible for managing the affairs of the Board to ensure that it functions effectively and efficiently. The Company has developed a written description for the role of the Chair. The responsibilities of this role include:

• Provide leadership to enable Board to act in carrying out its duties and responsibilities as described in the Board charter and as otherwise may be appropriate;
   
• Work with the CEO and other officers to monitor progress on the business plan, annual budgets, policy implementation and succession planning;
   
• Providing advice and mentorship to the CEO;
   
• Provide advice, counsel mentorship to the CEO and fellow members of the Board;
   
• Chairing Board meetings and liaising with the Corporate Secretary in respect of meeting logistics, and to ensure all required business and items requiring approval are brought before the Board;
   
• Facilitating in-camera sessions at Board meetings without the presence of management;
   
• Ensuring the proper flow of information between management and the Board;
   
• Chair the annual, and any special meeting, of the Shareholders; and
   
• Exercise the authority of the CEO in the unlikely event that the CEO is absent and is unable to act and action on the part of the CEO when required to protect the interests of the Company.

The Board has also appointed an Independent Lead Director to assist the Board Chair and provide leadership so that the Board can function independently. The Independent Lead Director is responsible for coordinating the activities of the other independent directors and perform such other duties and responsibilities as the Board may determine.

Strategic Planning

The Board and management generally conduct an annual strategic planning session to discuss updates to the Company's corporate strategy. The strategic planning session typically occurs prior to the budget approval process for the following year to facilitate the review of the Board of proposed budgets, taking into consideration the overall corporate strategy and direction of the Company. Financial forecasts for the Company are also presented to the Board together with a fulsome review of the Company's risk assessment matrix under its enterprise risk management system.

The Board exercises its oversight of management's performance on execution of the Company's strategy by receiving:

• Presentations from management at least quarterly on items including the status of the Company's projects and development operations including construction and development activities, budget performance to date, safety and health, community relations, the environment and sustainability, litigation involving the Company's material projects, investor relations matters, and human resources; and
• Informal updates from management on material developments or items of interest to directors.

Committees of the Board

The Board has three (3) standing committees, each with a written charter setting out the duties and responsibilities for the committee and its members, areas of committee oversight and the process for reporting to the Board. Directors are appointed annually to the committees after the annual meeting of Shareholders. The current members of each committee and their independence status are set out below.

Audit and Risk Committee

The Audit and Risk Committee assists the Board in its oversight functions as they relate to the integrity of the financial statements and financial reporting, accounting processes, internal controls, and matters concerning independent External Auditors, including direct communication with External Auditors.

• Overseeing certain risk management systems and practices adopted by the Company.

All members of the Audit and Risk Committee are financially literate, and two members are designated as financial experts, being Robert Doyle and Calum Morrison. "Financially literate" means they have the ability to read and understand a company's financial statements of a similar level of extent and complexity as can be expected of the financial reporting by the Company.

Based on their business and educational experiences, each Audit and Risk Committee member has a reasonable understanding of the accounting principles used by the Company; an ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves; experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of issues that can reasonably be expected to be raised by the Company's financial statements, or experience actively supervising one or more individuals engaged in such activities; and an understanding of internal controls and procedures for financial reporting. All members of the Audit and Risk Committee have had several years of experience in senior executive roles or as board members of significant business enterprises in which they assumed substantial financial and operational responsibility.

• The review and monitoring of Company's sustainability reporting, as well as the Company's alignment and audits against sustainability.

The proper care of the environment and the health and safety of our workforce is integral to our organization and the communities in which it operates. Accordingly, Lithium Argentina and its subsidiaries conduct operations with a focus on sustainability, and protecting and minimizing impacts to our local communities, the environment and wildlife to the extent possible. Our commitment extends to, among other things:

• Complying with the standards set by the applicable environmental laws and regulations of the countries and regions in which we operate, and additional environmental standards and practices that are voluntarily adopted by the Company;
   
• Exploring, designing, constructing, operating and planning for closures of mining and processing operations by utilizing effective and proven practices that minimize adverse environmental impacts;
   
• Educating employees regarding environmental matters, promoting employee participation in identifying opportunities to minimize environmental impacts, and asking that our employees behave in a manner which recognizes the Company's social responsibility;

Committee oversight also extends to setting annual corporate goals and objectives for the Company, which in turn form the basis for performance evaluations for our senior management. The committee also determines performance-based awards for the CEO and Executive Chair based on their annual performance reviews.

All members of this committee have the skills and experience necessary to oversee compensation matters based on their prior management roles with public and private companies.
