Lithium Americas Corp. (TSX: LAC) (NYSE: LAC) (“Lithium Americas”or the“Company”)announced an increased mineral resource and mineral reserve estimate for the Thacker Pass lithium project in Humboldt County, Nevada (“Thacker Pass” or the “Project”), including the release of an independent National Instrument 43-101 (“NI 43-101”) technical report (“Technical Report”) entitled “NI 43-101 Technical Report on the Thacker Pass Project Humboldt County, Nevada, USA,” and an independent S-K 1300 technical report (the “S-K 1300 Technical Report”) entitled “S-K 1300 Technical Report on the Thacker Pass Project Humboldt County, Nevada, USA,” both dated effective December 31, 2024. The Project is indirectly owned by Lithium Nevada Ventures LLC (“LN”). LN is a joint venture between the Company, which has a 62% ownership, and General Motors Holdings LLC (“GM”), which has a 38% ownership.

Jonathan Evans, President and CEO, commented, “We are excited to release the results of our Thacker Pass Technical Report that demonstrates the multigenerational opportunity for transformational growth the Project creates. Thacker Pass is now the largest measured lithium reserve and resource in the world and has the potential to become an unmatched district, generating American jobs and helping the U.S. regain independence of its energy supply. We are committed to safely and sustainably developing Thacker Pass while engaging with our stakeholders to increase domestic production of critical minerals.”

HIGHLIGHTS

  • Proven and Probable (“P&P”) mineral reserve estimate of 14.3 million tonnes (“Mt”) lithium carbonate equivalent (“LCE”) at an average grade of 2,540 parts per million (“ppm”) lithium (“Li”), an increase of 286% since the November 2022 Feasibility Study1; supports an expansion of up to five phases with an 85-year mine life.
  • Measured and Indicated (“M&I”)mineral resource estimate of 44.5 Mt LCE at an average grade of 2,230 ppm Li; an increase of 177% since the November 2022 Feasibility Study.
  • Expansion plan targeting 160,000 tonnes per year (“t/y”) of battery-quality lithium carbonate (“Li2CO3”) production capacity in four phases of 40,000 t/y each, respectively (“Phase 1,” “Phase 2,” “Phase 3” and“Phase 4”), with a sulfuric acid plant without an additional Li2CO3 production circuit as Phases 1-4 are expected to have excess capacity (“Phase 5”). Phase 4 expansion incorporates a direct rail line from Winnemucca to Thacker Pass.
  • Project economics for an 85-year life of mine (“LOM”) (“Base Case”) and an optimized production scenario for years 1-25 of the 85-year LOM (“Years 1-25” or “Production Scenario”). Both the Base Case and Production Scenario use a price assumption of $24,000 per tonne of Li2CO3.
    • Average annual EBITDA2 for the Production Scenario is estimated at $2.2 billion per year and $2.1 billion per year for the Base Case.
    • Production Scenario after-tax net present value (“NPV”) of $5.9 billion at 8% discount and 19.6% after-tax internal rate of return (“IRR”), and Base Case after-tax NPV of $8.7 billion at 8% discount and 20.0% after-tax IRR.
  • Production Scenario operating costs (“OPEX”) of $6,238 per tonne lithium carbonate produced, and Base Case OPEX of $8,039 per tonne lithium carbonate produced.
  • Capital cost (“CAPEX”) estimates for Phase 1 of $2.93 billion (as previously disclosed in March 2024), Phase 2 of $2.33 billion, Phase 3 of $2.74 billion, Phase 4 and 5 together of $4.32 billion, based on cost estimates from Q2 2024 and include a 15% contingency.
  • Construction of each of Phases 1 through 4 is expected to be spaced four years apart, with Phase 5 beginning at the same time as Phase 4.
  • Phase 1 is expected to create nearly 2,000 jobs during construction and approximately 350 full-time jobs during operations. Over the LOM, an average of approximately 1,100 full-time employees are expected to support mining and processing operations. Additional jobs are expected to be created in the local communities through ancillary and support services, such as transportation, maintenance and supplies.
  • Phase 1 is targeted for completion in late 2027. The Company is targeting to announce the final investment decision (“FID”) for Phase 1 in early 2025. Bechtel is the engineering, procurement and construction management (“EPCM”) contractor for the construction of Phase 1.

PROJECT IMPROVEMENTS

The Thacker Pass Technical Report results reflect continuous improvement initiatives, including optimizing the mine plan and incorporating results of test work completed at the Company’s Lithium Technical Development Center.

The Thacker Pass deposit allows the mine to have multiple grades of ore exposed at any given time, enabling flexibility to deliver optimum ore blends as needed to maximize economics. The Company has developed an optimized mine plan which allows an approximate 25% increase in recovery for the first 12 years of production, providing a higher economic return during the years of capital investment for building Phases 2 through 5.

Process optimizations and engineering development updates include:

  • Beneficiation circuit: the number of decanter centrifuges reduced from six to four.
  • Counter-current Decantation (“CCD”) thickeners: smaller diameter.
  • Filter presses: reduced from eight membrane type to four recessed chamber type.
  • Brine evaporators: reduced from three to two.
  • Sulfuric acid plant for Phase 1 through 4: size of plant reduced from the previous 3,000 tonnes per day (“t/d”) sulfuric acid to 2,250 t/d sulfuric acid, reducing the transportation and consumption of liquid sulfur.
  • Final polishing step where low levels of calcium and magnesium are removed: improved reaction parameters in the calcium precipitation circuit reduce loading on ion exchange.
  • Reagents: reduced soda ash consumption in the lithium carbonate circuit.

To maximize the life of mine, ore control parameters would be lowered after the construction of Phase 1 through 5 is completed. Phase 5 would consist of a 3,000 t/d sulfuric acid plant and a brine plant to supplement feed to the processing plants of Phases 1 through 4, to maintain their nominal production capacity at 40,000 t/y.

Estimated OPEX for Years 1-25 is approximately $500 per tonne lower (~7%), than the November 2022 Feasibility Study. Lower raw material (reagent) consumption and costs, decreased maintenance on less equipment and reduced tailings placement (due to less tailings produced) were offset by higher mining costs to achieve the optimized mine plan, power utility costs based on final selection of power provider and general and administrative costs for insurance.

CONSTRUCTION TIMELINE

Construction of Thacker Pass to reach total nominal design capacity of 160,000 t/y of Li2CO3 is planned over five phases. Each of Phases 1 through 4 are expected to be spaced 4 years apart with Phase 5 beginning at the same time as Phase 4. Construction of Phases 2 through 5 is expected to occur over a 13-year period, from the start of Phase 1 first production. Phase 4 expansion includes a direct rail line to Thacker Pass for the transportation of raw materials and finished product. The lithium carbonate production plants for Phase 1 through 4 is expected to have excess capacity that would take brine feed from Phase 5 to maintain their nominal production capacity of 40,000 t/y. Additional required permitting for Phases 2 through 5 will be initiated following the completion of Phase 1 construction.

Construction of Phase 1 commenced in early 2023 and the Company is targeting to announce FID in early 2025. Bechtel is the EPCM contractor for the construction of Phase 1. In Q4 2024, the Company provided Bechtel and other major contractors with limited full notice to proceed to de-risk the construction schedule and continue to target completion in late 2027.

Current work at Thacker Pass for Phase 1 includes excavation of the process plant (now over 75% complete), advancing detailed engineering (now over 50% complete) and awarding of procurement packages. At the Workforce Hub, the Company’s full-service housing facility in Winnemucca for construction workers, the site’s utility infrastructure is being built out.

CAPITAL COST ESTIMATE

Total estimated CAPEX for the development of Phases 1 through 5 for total nominal production of 160,000 t/y of lithium carbonate is $12.4 billion. CAPEX estimates are based on Q2 2024 pricing and include a 15% contingency. CAPEX estimates include early works, mine development, mining, the process plant, the off-site transload facility, commissioning and all associated infrastructure.

CAPEX for Phase 2, 3, 4 and 5 is derived from Phase 1 estimates. CAPEX for Phases 2 and 3 benefits from established mine and plant infrastructure from Phase 1. CAPEX for Phases 4 and 5 include the addition of one processing plant, two sulfuric acid plants and a direct rail line to Thacker Pass.

  2. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
  3. The Mineral Resource model has been generated using Imperial units. Metric tonnages shown in table are conversions from the Imperial Block Model.
  4. Mineral Resources are inclusive of 1,056.7 million metric tonnes (Mt) of Mineral Reserves
  5. Mineral Resources are reported using an economic break-even formula: “Operating Cost per Resource Short Ton”/“Price per Recovered Short Ton Lithium” * 10^6 = ppm Li Cutoff. “Operating Cost per Resource Short Ton” = US$86.76, “Price per Recovered Short Ton Lithium” is estimated: “Lithium Carbonate Equivalent (LCE) Price” * 5.3228 * (1 – “Royalties”) * “Metallurgical Recovery”. Variables are “LCE Price” = US$26,308/Short Ton ($29,000/tonne) Li2CO3, “GRR” = 1.75% and “Metallurgical Recovery” = 73.5%.
  6. Presented at a cutoff grade of 858 ppm Li. and a maximum ash content of 85%.
  7. A mineral resource constraining pit shell has been derived from performing a pit optimization estimation using Vulcan software and the same economic inputs as what was used to calculate the cutoff grade.
  8. The conversion factor for lithium to LCE is 5.3228.
  9. Applied density for the mineralization is weighted in the block model based on clay and ash percentages in each block and the average density for each lithology (Section 14.1.6.4 of the Technical Report).
  10. Measured Mineral Resources are in blocks estimated using at least 3 drill holes and 10 samples where the closest sample during estimation is less than or equal to 900 ft. Indicated Mineral Resources are in blocks estimated using at least 2 drill holes and 10 samples where the closest sample during estimation is less than or equal to 1,500 ft. Inferred Mineral Resources are in blocks estimated using at least 2 drill holes and 9 samples where the closest sample during estimation is less than or equal to 2,500 ft.
