Cauchari-Olaroz is 100% owned by Minera Exar S.A. an Argentine company owned 50/50 by Lithium Americas and Sociedad Quimica y Minera de Chile S.A. As previously announced, Minera Exar is pursuing a development plan at Cauchari-Olaroz for production capacity of 50,000 tonnes per annum of battery-grade lithium carbonate (“Li₂CO₃“) in two stages, with each stage consisting of 25,000 tpa of Li₂CO₃. The Stage 1 DFS covers the first stage (“Stage 1”) and the plant for Stage 1 has been engineered to integrate production from the second stage (“Stage 2”). No estimated financial results or reserve estimate associated with Stage 2 are included in the Stage 1 DFS.

The results of the Stage 1 DFS are provided in Table 1 on a 100% equity project basis:

Tom Hodgson, CEO of Lithium Americas, commented: “We are very pleased with the results of the Stage 1 DFS, which highlights the value created from our partnership with SQM, our experienced team in Argentina and strong support from the government of Jujuy. The Stage 1 DFS leverages our partner’s expertise to develop a low-cost and long-life lithium project. We plan to start construction immediately upon closing our strategic investments with Ganfeng Lithium and Bangchak Petroleum, which are expected to close in the coming month.”

Project Details

Cauchari-Olaroz is located in Jujuy Province in north-west Argentina. The Project is situated in the Salar de Olaroz and Salar de Cauchari, adjacent to Orocobre Ltd.’s Olaroz facility, which has been in production since 2015. The Project is approximately 270 km east of SQM’s Salar de Atacama brine operation, accessible via an international highway. Cauchari-Olaroz is well serviced by nearby infrastructure including major paved highways, a national and international rail link which connects to the port of Antofagasta in Chile, a high-voltage power grid, and a gas pipeline.

The Stage 1 DFS is based on using a conventional, commercially-proven brine processing technology at Cauchari-Olaroz to produce high quality battery-grade lithium carbonate that can be used directly by battery material producers in manufacturing cathode and electrolyte for lithium-ion batteries.

The production process involves two distinct steps and is generally consistent with other established brine operations. The first step uses a solar evaporation process to concentrate lithium in the brine and precipitate competing salts in large-scale ponds. The ponds at Cauchari-Olaroz are based on SQM’s pond design criteria used in their existing Atacama operation and involve the use of shallow ponds where the precipitated salt is annually harvested from the flat pond base. The second step uses the processing facilities that transform the concentrated lithium brine into battery-grade lithium carbonate while ensuring the removal of impurities from the end-product.

The Stage 1 DFS contemplates producing 25,000 tpa of battery-grade Li₂CO₃ for a project life of 40 years with production starting in 2019 The production and sale of potassium chloride (“KCl”) is not contemplated in the Stage 1 DFS.

Minera Exar has granted a right to Jujuy Energia y Mineria Sociedad del Estado a mining investment company owned by the government of Jujuy Province in Argentina, to acquire an 8.5% equity interest in Minera Exar and provide management services as required to develop the Project.

Permitting Status

Minera Exar has an approved Environmental Impact Statement permit issued by the Province of Jujuy on July 11, 2012. Minera Exar’s permitting status was recently affirmed by a letter from the Secretary of Mining and Hydrocarbons of the Province of Jujuy on March 21, 2017 confirming that Cauchari-Olaroz has the necessary permits to commence construction and operate in accordance with the EIS.

Economic Benefits to Jujuy Province and Argentina

The Stage 1 DFS demonstrates that Cauchari-Olaroz will provide substantial economic benefits to Argentina at the local, provincial, and national levels, including:

• Direct employment by Minera Exar of at least 800 people during the 2-year construction period;
• Direct employment by Minera Exar of at least 260 people in permanent positions during the 40 year operations;
• Several hundred indirect jobs with suppliers of products and services to support mine operations;
• Annual payments to the government totaling approximately $63 million in the form of income tax, corporate tax, and royalties (based on a price of $12,000/t of Li₂CO₃);
• Training and skills development programs aimed at maximizing local employment at the Project;
• Expected improvement of local and regional infrastructure; and
• Continuation and future expansion of existing community investment programs, small business development, and support of cultural development.

Operating Costs

The operating and capital cost estimates have been reviewed and confirmed by Andeburg Consulting Services Inc in accordance with NI 43-101 Standards of Disclosure for Mineral Projects. The Project cost estimates are based on an exchange rate of 16:1 Argentine pesos to the U.S. dollar. The average operating costs were calculated for a facility with production of 25,000 tpa of battery-grade Li₂CO₃, and are presented below in Table 2. Additional work through engineering refinements and contract negotiation will continue in an effort to reduce the operating expenditures.

Capital Costs

The construction capital cost estimates are based on current Argentine costs for labor and materials. The Stage 1 construction capital cost is estimated at $425 million inclusive of a 15% contingency. Construction and commissioning will take approximately two years. Detailed capital cost estimates are presented in Table 3 and are exclusive of VAT and working capital. During construction, VAT and working capital are expected to total $51.1 million and $12.5 million, respectively. The VAT is refundable with an average repayment period of 2 years.

The sustaining capital requirement is estimated at an average of $4.7 million per year (approximately $190/t Li₂CO₃ produced).

Lithium Americas will be responsible for contributing 50% of capital expenditures for development of the project, amounting to approximately $212.5 million.

Project Economics

The financial results are derived from inputs based on an annual production schedule included in the Stage 1 DFS. A sensitivity analysis on the unlevered economic results for the 25,000 tpa of Li₂CO₃ over a 40-year operating period are summarized in Table 4 and 5 and reported on a 100% equity project basis.

Mineral Resource Estimation

The Mineral Resources for Cauchari-Olaroz remain unchanged from the technical report entitled “Feasibility Study – Reserve Estimation and Lithium Carbonate and Potash Production at the Cauchari-Olaroz Salars, Jujuy Province, Argentina” with an effective date of July 11, 2012. Mineral Resources are summarized in Table 6 and reported on a 100% equity project basis.

Notes:

1) Mineral Resources have a cut-off grade of 354 mg/L of lithium.

2) Mineral Resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resource will be converted to mineral reserves.

3) Lithium carbonate equivalent (“LCE”) is calculated based the following conversion factor: Mass of LCE = 5.323 x Mass of lithium metal

4) The values in the columns on Lithium Metal and Lithium Carbonate Equivalent above are expressed as total contained metals within the relevant cut-off grade.

Mineral Reserve Estimation

Consultants Montgomery & Associates Inc. were engaged to update the Mineral Reserves in brine for various areas within the Salar de Cauchari and Salar de Olaroz in accordance with the guidelines for lithium brines set forth by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM 2012). The reserve estimate was based on numerical model simulations that demonstrated a sustainable maximum production rate of over 25,000 tpa of LCE for 40 years. The proven reserves include brines sourced entirely within the project’s property boundaries, while 99.9% of the probable reserves are sourced within the project boundary. Simulated well field pumping was constrained by restricting drawdown to a maximum of 100 m at any given production well. A minimum cut-off value was not required in the reserve estimate because average lithium concentrations after 40 years of simulated pumping decreased marginally from 713 mg/L to 695 mg/L, which is significantly above economic mineral cut-off criteria.

Mineral Reserves for Cauchari-Olaroz have an effective date of March 5, 2017. Mineral Reserves are summarized in Table 7 and are reported on a 100% basis.

Notes:

1) Ratios of lithium to other metals include: K:Li of 8.2, Mg:Li of 2.4, B:Li of 1.6, SO₄:Li of 28.5.

2) LCE is calculated based the following conversion factor: Mass of LCE = 5.323 x Mass of lithium metal

3) The conversion is direct and does not account for estimated processing losses.

4) The values in the columns on Lithium Metal and Lithium Carbonate Equivalent above are expressed as total contained metals.

Conclusions and Next Steps

Lithium Americas contemplates that Minera Exar will commence construction immediately following the close of the Ganfeng Lithium and Bangchak Petroleum investment agreements. The construction timetable is targeted to follow:

•  H1 2017 – Site preparation and camp construction
•  H2 2017 – Pond construction and wellfield installation commences
•  2018 – Plant construction; offsite infrastructure
•  2019 – Commissioning and first production
