Highlights

Cauchari-Olaroz Lithium Project ('Cauchari-Olaroz')

Construction activities at Cauchari-Olaroz continue to advance in accordance with the 40,000 tonne per annum ('tpa') of battery-quality lithium carbonate development plan.

Currently, there are more than 1,000 construction personnel on site, including 286 full-time employees in Jujuy, Argentina.

Construction is approximately 36% complete, as of the end of February 2020, and continues to advance on budget.

As of February 29, 2020, $331 million (59%) of the planned capital expenditure has been committed of which $222 million (39%) has been spent.

Contracts associated with the 33 kV powerline and the 13.2 kV distribution lines were awarded, the contractors were mobilized and the development activities have commenced.

The gas pipeline contract was awarded, and the contractor commenced development activities at site.

The construction camp has close to 1,000 beds available and completion of the remaining bed modules is expected by the end of Q1 2020.

Earthworks for the carbonate plant site have been completed.

98% of the total planned earthworks for the 12 square kilometer evaporation pond layout are completed and approximately 38% of the liner has been installed.

The concrete foundation for the boron solvent extraction plant is approximately 60% complete.

Construction of buildings for storage of soda ash, reagents, finished products and other warehouses is 99% complete.

The development plan contemplates that construction will be substantially mechanically complete by the end of 2020; however, several major pieces of equipment for the chemical plant are being fabricated in China and some suppliers have sub-vendors fabricating in China. The Company has become aware that there will be delays of up to 90 days in the delivery time for some of these items as a result of the recent COVID-19 outbreak. Accordingly, the Company anticipates that there will be a delay in achieving substantial completion of construction until early 2021. The Company continues to assess the impact of COVID-19 on the development program, including discussions with all vendors and freight forwarders on the delivery schedule, to assess the impact on schedule and to develop mitigation strategies, if necessary. The Company intends to provide updated guidance on the construction schedule in Q2 2020.

Thacker Pass Lithium Project ('Thacker Pass')

Permitting continues as planned, with the Mine Plan of Operations accepted by the Bureau of Land Management ('BLM') and the Notice of Intent published on January 21, 2020 in the federal register, which started a mandated 365 day requirement for the BLM to complete the permitting process. Major permits for Phase 1 (as defined further below) are expected to be received by early 2021.

Over 10,500 kg of high-quality lithium sulphate has been produced at the process testing facility in Reno, Nevada.

Third-party vendors are engaged to engineer and design lithium carbonate and lithium hydroxide evaporator and crystallizer as well as provide performance guarantees and product samples.

A definitive feasibility study ('DFS') is being completed with an initial targeted production capacity of 20,000 tpa lithium hydroxide and approximately 2,000 tpa lithium carbonate ('Phase 1'); the DFS is on track to be complete by mid-2020.

The Industrial Company, a division of Kiewit, is engaged to complete key aspects of the feasibility study.

Project permitting and DFS costs are expected to be fully funded from available cash on hand.

The Company is exploring financing options, including the possibility of a joint venture partner at Thacker Pass.

In addition, Lithium Americas will receive $40.0 million in cash from the proceeds of non-interest-bearing loans from Ganfeng. Ganfeng has commenced the regulatory approval application process in China and the transaction is expected to be completed in Q3 2020.

Financial Results

Following closing of the $160.0 million investment by Ganfeng in Cauchari-Olaroz (the 'Project Investment') in August, 2019 the Company's investment in Cauchari-Olaroz is accounted for as a joint operation and the Company now recognizes its share of any assets, liabilities and results of the joint operation rather than equity accounting for the investment. In 2019, total assets increased primarily as a result of recognizing the Company's 50% share of Cauchari-Olaroz's cash of $52.5 million, property, plant and equipment of $156.9 million and other assets. In 2019, total long-term liabilities increased primarily as a result of recognizing the Company's share of its joint operation's borrowings of $28.9 million and drawdowns from the Company's senior credit facility of $66.3 million.

Net income for the year ended December 31, 2019 was $51.7 million compared to net loss of $28.3 million for the year ended December 31, 2018. Net income in 2019 is primarily a result of a gain on closing of the Project Investment of $74.5 million.
