&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) an approximate US$320 million first tranche investment, pursuant to which GM will acquire 15,002,243 common shares of Lithium Americas (each, a "**LAC Share**") at a price of US$21.34 per LAC Share, representing approximately 9.999% of the issued and outstanding LAC Shares; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) an approximate US$330 million second tranche investment, which is contemplated to be invested through a subscription for common shares in the enterprise that owns the U.S. business following the separation of its U.S. and Argentine businesses (the "**Separation**"), or if the Separation does not occur, into Lithium Americas.

Lithium Americas has agreed to use the proceeds from the Transaction for the development of Thacker Pass.

Lithium Americas has completed an updated construction plan for Thacker Pass, along with a feasibility study for Thacker Pass (the "**Feasibility Study**").

------

**Item 5 Full Description of Material Change**

***Investment Transaction***

Pursuant to the Master Purchase Agreement, GM has agreed to make an aggregate investment of US$650 million in two tranches.

<u>*Tranche 1*</u>

In tranche 1, GM will acquire 15,002,243 common shares of Lithium Americas (each, a "**LAC Share**") at a price of US$21.34 per share (the "**Tranche 1 Subscription Price**"), for gross proceeds of approximately US$320 million ("**Tranche 1**").

Tranche 1 of the Transaction will be structured through the initial issuance of 15,002,243 subscription receipts of Lithium Americas ("**Subscription Receipts**") to GM, whereby each Subscription Receipt will, upon satisfaction of the Escrow Conditions (as defined below), convert into a unit consisting of one LAC Share and 79.26% of a warrant (a "**Tranche 2 Alternative Exercise Warrant**" or "**Tranche 2 AEW**"), with each full Tranche 2 AEW exercisable into a LAC Share at a price of US$27.74 for a term of 36 months. The conversion of the Subscription Receipts will result in the issuance of all LAC Shares issuable for the Tranche 1 Investment and, through the LAC Shares issuable upon exercise of the Tranche 2 AEW, the allocation of all LAC Shares issuable under the Tranche 2 subscription.

The conversion of the Subscription Receipts to units will occur upon satisfaction of applicable escrow release conditions (the "**Escrow Conditions**"), including delivery of a ruling under the Thacker Pass Record of Decision ("**ROD**") appeal that does not result in vacatur of the ROD, and other closing conditions. If the Escrow Conditions are met, the funds will be released to the Company and GM will be issued 15,002,243 LAC Shares, representing an approximate 9.999% equity interest in Lithium Americas as at the date of the Master Purchase Agreement and 11,890,848 Tranche 2 AEWs. Additionally, the parties will execute and deliver the Offtake Agreement and the Investor Rights Agreement (as described below). The outside date for satisfaction of the Escrow Conditions and completion of Tranche 1 is December 31, 2023.

<u>*Tranche 2*</u>

Concurrent with completion of Tranche 1, GM and Lithium Americas have agreed to execute a subscription agreement (the "**Tranche 2 Subscription Agreement**") providing for the issuance of approximately US$330 million of LAC Shares at a price equal to the five-day volume-weighted average price for LAC Shares on the NYSE preceding that date that Lithium Americas delivers notice of satisfaction of closing conditions, subject to a maximum price of US$27.74 per LAC Share ("**Tranche 2**"). Completion of Tranche 2 is subject to several conditions, including Lithium Americas demonstrating that it has secured sufficient funding to complete the development of Phase 1 of Thacker Pass as set out in the Feasibility Study. The parties will implement the Tranche 2 investment as contemplated under the Investment Transaction either through completion of the Tranche 2 Subscription Agreement or through the exercise of the Tranche 2 Alternative Exercise Warrants. Each of the agreements contains cross-termination provisions, such that the completion of an investment under one agreement (being either the Tranche 2 Subscription Agreement or the Tranche 2 AEWs) results in the rights and obligations pertaining to the issuance of LAC Shares under the other agreement being terminated.

------

The parties contemplate that the Tranche 2 investment under the Investment Transaction will occur following the Separation. Accordingly, the transaction agreements provide that upon the Separation, the relevant agreements reflecting the Tranche 2 investment will be superseded by an equivalent agreement between GM and the new entity resulting from the Separation that holds Lithium Americas' U.S. business ("**Spinco**"), with maximum pricing (being US$27.74 per share) being adjusted to reflect the relative value of Spinco compared to the value of the enterprise that holds the Argentina business.

<u>*Shareholder Meeting*</u>

The Tranche 2 subscription will result in a maximum aggregate holding by GM of 19.9% of Lithium Americas (or Spinco, as applicable) unless Toronto Stock Exchange ("**TSX**") approval and requisite shareholder approvals are obtained to meet or exceed a 20% ownership interest by GM. To that end, Lithium Americas intends to hold a shareholders meeting (the "**Shareholders Meeting**") in conjunction with either or both of the next annual general meeting and the shareholders meeting for the Separation to approve the maximum pricing limitation under the Second Tranche Subscription Agreement of US$27.74 per LAC Share and to approve GM exceeding a 19.9% interest in Lithium Americas.

If shareholder approval is obtained to permit GM to hold in excess of 19.9%, there will be a contractual limitation on the subscription such that GM must not exceed a set threshold of Lithium Americas' (or Spinco's) share capital, being the lesser of 30% and the number of shares that would result in GM consolidating its interest in Lithium Americas in its financial statements (estimated to be greater than 30%).

<u>*Offtake Agreement*</u>

Concurrent with completion of Tranche 1, Lithium Americas and GM will enter into the Offtake Agreement. The purchase price for lithium carbonate under the Offtake Agreement will be based on an agreed upon price formula linked to prevailing market prices. The term of the Offtake Agreement will be 10 years from the commencement of Phase 1 commercial production, with an option for GM to extend by an additional five years. GM is entitled to purchase all offtake from Phase 1, unless it does not complete the full Investment Transaction and invest US$650 million, in which case its entitlement will be prorated (subject to certain exceptions).

GM will also have a right of first offer on the offtake of Thacker Pass' Phase 2 production. So long as the Offtake Agreement remains in good standing Lithium Americas has also agreed to limitations on the establishment of joint ventures and sale of an interest in Thacker Pass to certain competitors and enterprises restricted under governmental sanctions and under critical minerals policies of the United States and Canada.

------

*Investor Rights Agreement*

Concurrent with completion of Tranche 1, Lithium Americas and GM will enter into an investor rights agreement (the "**Investor Rights Agreement**" or "**IRA**"). Under the IRA, GM will be required to "lock-up" its securities until the later of (i) one year after the Separation, or (ii) the earlier of (i) six months after the closing of Tranche 2, or (ii) the date Tranche 2 is not completed in accordance with its terms, provided that the foregoing lock-up restriction will not apply if the Separation does not occur (such date being the "**Lock-up Outside Date**"). The Investor Rights Agreement also provides among other things, for GM to be entitled to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the right to nominate an individual to serve on the Board of Directors of Lithium Americas during the term leading up to Tranche 2 and thereafter for so long as it holds 10% or more of LAC Shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the right to have a non-voting observer (as an alternative to a board nominee) attend all Lithium Americas board meetings, during the term leading up to Tranche 2 and thereafter for so long as it holds 5% or more of LAC Shares; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the right to participate in any subsequent issuances of Lithium Americas securities to "top-up" its pro rata ownership of Lithium Americas, until the later of: (i) the Lock-up Outside Date, and (ii) the date on which GM ceases to either (i) own 10% or more of the issued and outstanding LAC Shares, or (ii) owns 5% or more of the issued and outstanding LAC Shares and be a party to the Offtake Agreement (or a similar agreement with Lithium Americas).

In addition, GM will be subject to a standstill limitation whereby it will not be able to increase its holdings beyond 20% of the issued and outstanding LAC Shares (excluding the acquisition of LAC Shares pursuant to the Investment Transaction), until the later of five years following the effective date of the Investor Rights Agreement and one year following the date of the commencement of commercial production for Phase 1.

<u>*General*</u>

Lithium Americas has agreed to use the proceeds from the Transaction for the development of Thacker Pass.

Completion of the Transaction remains subject to customary regulatory approvals, including approval of the TSX and the New York Stock Exchange ("**NYSE**"), and other closing conditions, including those described above.

A copy of the Master Purchase Agreement is available on the Company's page on SEDAR at www.sedar.com and on EDGAR at www.edgar.com.

***Thacker Pass Update - Feasibility Study***

In connection with the Transaction, Lithium Americas provided an update on the construction plan for Thacker Pass, including the release of the Feasibility Study.

------

The results of the Feasibility Study for Thacker Pass reflect operational and process improvements, including increased extraction rates from an optimized mine plan through new ore control strategy, an increase in sulfuric acid utilization by targeting illite clay with greater potential for increasing lithium extraction per tonne of sulfuric acid and increased crystallization steps to further remove magnesium impurities.

Other process and design improvements were made to further minimize the Project's environmental impact, including, increased capacity to 80,000 tpa within approximately the same mining footprint as the permitted pit boundary and without increasing the size of the sulfuric acid plant, additional beneficiation and neutralization circuits to increase the neutrality of filter pressed tailings and implementing a tail gas scrubber utilizing a neutralization solution in the sulfuric acid plant to minimize emissions and reduce impacts to ambient air quality.

<u>Note</u>:<br>1. The economic analysis is based on Q3 2022 pricing for capital and operating costs.

<u>2</u>. Based on Q3 2022 long-term lithium carbonate price outlook from a leading industry market consultant.

<u>*Construction Timeline*</u>

Phase 1 will consist of a single sulfuric acid plant with a nominal production rate of 3,000 tonnes per day ("**tpd**") sulfuric acid. Phase 2 construction will begin upon completion of Phase 1, with the addition of a second sulfuric acid plant with an additional nominal production rate of 3,000 tpd.

Total designed capacity of 80,000 tpa Li<sub>2</sub>CO<sub>3</sub> production upon completion of both Phase 1 and Phase 2. Actual production varies by year with anticipated average production of approximately 70,000 tpa Li<sub>2</sub>CO<sub>3</sub> in the first 25 years and approximately 67,000 tpa over LOM, including ramp up of Phase 1 and Phase 2.

The Company continues to prepare for construction while we await a ruling for the appeal of the issuance of the ROD following a hearing held by the US District Court, District of Nevada ("**Federal Court**") on January 5, 2023. During the hearing, plaintiffs and the Company addressed final questions, the Federal Court reaffirmed no additional hearings or briefings are required and they expect to issue a decision in the next couple months.

<u>*Capital Cost Estimate*</u>

The initial capital cost estimate covers early-works, mine development, mining, the process plant, the off-site transload facility, commissioning and all associated infrastructure.

The capital cost estimates include a 13.1% contingency. The Phase 2 estimate is derived from the Phase 1 estimate and the lower Phase 2 estimated capital costs are a result of mine development, infrastructure and transload facility synergies.

---

| | | |
|:---|:---|:---|
| **Initial Capital Costs ($ millions)** | **Phase 1 Costs** | **Phase 2 Costs** |
| Mine | $58 | $30 |
| Process Plant and Infrastructure | $1963 | $1582 |
| Offsite - Transload Facility | $78 | $31 |
| Owner's Costs | $169 | $86 |
| **Total Initial Capital Costs** | **$2268** | **$1729** |

---

In addition to the initial capital costs, $50 million in mining equipment cost will be repaid to the mining contractor over the first five years of production.

Sustaining capital costs include replacement costs for mining equipment, process plant equipment, and expansions of storage facilities and infrastructure.

<u>*Operating Cost Estimate*</u>

Operating costs in each area include labor, maintenance materials and supplies, raw materials, and outside services, among others. Reagents account for approximately 63% of LOM total operating costs for the process plant and the sulfuric acid plant. Primary reagents include liquid sulfur, limestone, soda ash, flocculant and quicklime.

Notes for the November 2, 2022 Mineral Resource:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Qualified Person who supervised the preparation of and approved disclosure for the estimate is Benson Chow, P.G., SME-RM.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Mineral Resources are inclusive of 217.3 million metric tonnes (Mt) of Mineral Reserves.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Mineral Resources are reported using an economic break-even formula: "Operating Cost per Resource Tonne"/"Price per Recovered Tonne Lithium" \* 10^6 = ppm Li Cutoff. "Operating Cost per Resource Tonne" = US$88.50, "Price per Recovered Tonne Lithium" is estimated: ("Lithium Carbonate Equivalent (LCE) Price" \* 5.323 \*(1 - "Royalties") \* "Recovery". Variables are "LCE Price" = US$22,000/tonne Li<sub>2</sub>CO<sub>3</sub>, "Royalties" = 1.75% and "Recovery" = 73.5%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Presented at a cutoff grade of 1,047 ppm Li.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. A resource constraining pit shell has been derived from performing a pit optimization estimation using Vulcan software.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. The conversion factor for lithium to LCE is 5.323.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. Applied density for the mineralization is 1.79 t/m<sup>3</sup>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. Measured Mineral Resources are in blocks estimated using at least six drill holes and eighteen samples within a 262 m search radius in the horizontal plane and 5 m in the vertical direction; Indicated Mineral Resources are in blocks estimated using at least two drill holes and six to eighteen samples within a 483 m search radius in the horizontal plane and 5 m in the vertical direction; and Inferred Mineral Resources are blocks estimated with at least two drill holes and three to six samples within a search radius of 722 m in the horizontal plane and 5 m in the vertical plane.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. Tonnages and grades have been rounded to accuracy levels deemed appropriate by the QP. Summation errors due to rounding may exist.

Notes for the November 2, 2022 Mineral Reserve:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Qualified Person who supervised the preparation of and approved disclosure for the estimate is Kevin Bahe, P.E., SME-RM.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Mineral Reserves have been converted from measured and indicated Mineral Resources within the feasibility study and have demonstrated economic viability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Reserves presented at an 85% maximum ash content and 1.533 kilogram of lithium recovered per run of mine feed cutoff grade. A sales price of $5,400 US$/t of Li2CO3 was utilized in the pit optimization resulting in the generation of the reserve pit shell in 2019. Overall slope of 27 degrees was applied. For bedrock material pit slope was set at 47 degrees. Mining and processing cost of $57.80 per tonne of ROM feed, a processing recovery factor of 84%, and royalty cost of 1.75% were additional inputs into the pit optimization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. A LOM plan was developed based on equipment selection, equipment rates, labor rates, and plant feed and reagent parameters. All Mineral Reserves are within the LOM plan. The LOM plan is the basis for the economic assessment within the NI 43-101 technical report titled "Feasibility Study, National Instrument 43-101 Technical Report for the Thacker Pass Project Humboldt County, Nevada, USA" with an effective date of November 2, 2022, which is used to show economic viability of the Mineral Reserves.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. The reference point at which the Mineral Reserves are defined is at the point where the ore is delivered to the run-of-mine feeder.

Please refer to the NI 43-101 technical report titled "*Feasibility Study, National Instrument 43-101 Technical Report for the Thacker Pass Project Humboldt County, Nevada, USA*" with an effective date of November 2, 2022 (the "**Technical Report**"), for full details on the geology, mining, processing and infrastructure of Thacker Pass.

<u>*Mineral Reserve Estimate Methodology*</u>

The Mineral Reserves estimate in the Technical Report is based on current knowledge, engineering constraints and permit status. A qualified person, as defined under NI 43-101 ("**QP**"), has reviewed and verified the Mineral Reserve estimate (the "**Mineral Reserves QP**"), and is of the opinion that the methodology for estimation of Mineral Reserves in the Technical Report is in general accordance with the 2019 CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines, and using the definitions in 2014 CIM Definition Standards for the classification of Mineral Reserves. Large changes in the market pricing, commodity price assumptions, material density factor assumptions, future geotechnical evaluations, cost estimates or metallurgical recovery could affect the pit optimization parameters and therefore the cutoff grades and estimates of Mineral Reserves.

<u>*Mineral Resource Estimate Methodology*</u>

A QP has reviewed and verified the Mineral Resources estimate (the "**Mineral Resources QP**") and is of the opinion that the Mineral Resource estimation methodology is in general accordance with the 2019 CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines and uses the definitions in 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves for the classification of Mineral Resources. Potential risk factors that could affect the Mineral Resource estimates include but are not limited to large changes in the market pricing, commodity price assumptions, material density factor assumptions, future geotechnical evaluations, metallurgical recovery assumptions, mining and processing cost assumptions, and other cost estimates could affect the pit optimization parameters and therefore the cutoff grades and Mineral Resource estimates.

<u>*Quality Assurance and Quality Control*</u>

*Mineral Resources* 

Sample names, certificate identifications, and run identifications were cross referenced with the laboratory certificates and sample assay datasheet for spot checking and verification of data. No data anomalies were discovered during this check.

Quality Assurance / Quality Control ("**QA/QC**") methodology utilized by Lithium Americas and results of these checks were discussed between Lithium Americas' geologists and the Mineral Resources QP.

------

Geologic logs, Access databases, and Excel spreadsheets were provided to the Mineral Resources QP for cross validation with the Excel lithological description file. Spot checks between Excel lithological description sheets were performed against the source data with no inconsistencies found with the geologic unit descriptions.

Verification of the block model was performed by the creation of a geostatistical model and the review of its various outputs. Histograms, HERCO grade tonnage curves, and swath plots were created and analyzed to validate the accuracy of the block model.

Based on the various reviews, validation exercises and remedies outlined above, the Mineral Resources QP concluded that the data is adequate for use for Mineral Resource estimation.

*Mineral Reserves* 

The Mineral Reserves QP reviewed the following as part of the mine planning, cost model and Mineral Reserves data verification.

* Geotechnical: slope stability study completed by BARR Engineering in 2019 was reviewed.

* Mining Method: open-pit mining with limited blasting has been reviewed and assessed with geotechnical reports.

* Pit Optimization: the pit limits were established based on the Environmental Impact Statement pit extents and physical features. The final pit shell was verified to provide a positive economic value.

* Mine Design: ramp, bench and face angle parameters were validated by geotechnical reports.

* Production Schedule: the production schedule was validated based on reasonability.

* Labor and Equipment: estimations for equipment sizes, capacity, availability and utilization were reviewed for reasonability.

* Economic Model: model was reviewed and demonstrated economic viability for the project.

* Facilities and Materials: facilities and materials located within the reserve pit boundary will be re-located when access to those areas are required during mining.

A news release with respect to the contents of this report was issued on February 7, 2023 and was disseminated through the facilities of recognized newswire services. A copy of the new release was filed on SEDAR.

**Item 4 Summary of Material Change**

Lithium Americas received a favorable ruling from the US District Court, District of Nevada ("**Federal Court**") on February 6, 2023, for the appeal filed against the Bureau of Land Management ("**BLM**") for the issuance of the Record of Decision ("**ROD**") relating to the Company's 100%-owned Thacker Pass project ("**Thacker Pass**" or the "**Project**") located in Humboldt Country, Nevada. The Federal Court has declined to vacate the ROD for the mining Plan of Operations (the "**Federal Permit**").

**Item 5 Full Description of Material Change**

Lithium Americas received a favorable ruling from the Federal Court on February 6, 2023, for the appeal filed against the BLM for the issuance of the ROD relating to the Company's 100%-owned Thacker Pass project located in Humboldt Country, Nevada. The Federal Court has declined to vacate the Federal Permit. The Federal Court ordered the BLM to consider one issue under the mining law relating to the area designated for waste storage and tailings and did not impose any restrictions expected to impact the construction timeline. The Federal Court rejected arguments that the Project will cause unnecessary and undue degradation to the local sage grouse population and habitat, groundwater aquifers and air quality; that the BLM failed to adequately assess the Project's impacts on air quality, wildlife and groundwater; that the BLM failed to adequately consider the Project's impacts to culturally or religiously significant areas; and that BLM acted unreasonably or in bad faith in identifying tribes for consultation before approving the Project. The remand issued by Federal Court to the BLM is to determine whether the Company possesses adequate mining-claim rights to the lands over the area in which the waste storage and tailings are expected to be located, based on an appellate decision that was issued after the BLM issued its ROD for Thacker Pass.
