Regulatory & Permitting 

Federal National Environmental Policy Act
Lithium Nevada has submitted environmental baseline studies that inform the public agencies about the Project and related resources. The final Plan of Operation (“Final PoO”) was filed in August 2019 and deemed complete by the Bureau of Land Management (“BLM”) in September 2019. A third-party contractor has been selected by the BLM to write the Environmental Impact Statement (“EIS”) which is scheduled to be complete by the end of 2019. The EIS will assist federal, state and local regulatory agencies in their review of the Company’s applications for environmental and land-use permits. Upon completion of the EIS, the BLM is expected to issue a Notice of Intent that commences the formal National Environmental Policy Act (“NEPA”) EIS public process. The NEPA process is designed to help public officials complete permitting decisions that are protective of the environment and includes a public engagement process. Following the completion of a public process that is mandated to take no longer than twelve months, the BLM is expected to issue a Record of Decision (“ROD”). The Company’s engagement with government and Tribal stakeholders is planned to continue over the next year in anticipation of the ROD being issued in Q4 2020. The ROD will include the agency’s decision, alternatives considered and the plans for mitigation and monitoring, if necessary. The anticipated timing of key permitting milestones is highlighted in Figure 1.

Plan of Exploration
Effective as of August 1 2018, the Company updated the Measured and Indicated mineral resource at Thacker Pass to 6.0 million tonnes of lithium carbonate equivalent (“LCE”) at 2,917 parts per million lithium (“ppm Li”) (Measured 2.4 million tonnes at 2,948 ppm Li and Indicated 1.4 million tonnes 2,864 ppm Li, respectively) and the Inferred mineral resource to approximately 2.3 million tonnes of LCE at 2,932 ppm Li. Additional exploration targets have been identified outside the existing resource boundary. Prompted by the discovery of lithium mineralization in the Southwest Basin in 2017, Lithium Nevada has submitted permit applications for a proposed future exploration program in the southern and eastern areas of Thacker Pass as identified in Figure 2.

Water Rights 
Lithium Nevada has secured water rights that it believes will be sufficient to meet or exceed requirements for Phase 1 production. Use of the water rights will be subject to customary regulatory approvals including the transfer of the point of diversion, point of use and manner of use prior to production. 

Commercial Agreements

North American Coal
Lithium Nevada and Sawtooth Mining LLC (“Sawtooth Mining”) executed a long-term contract mining agreement (the “Mining Agreement”). Under the Mining Agreement, Sawtooth Mining will act as Lithium Nevada’s contract miner for Thacker Pass. By engaging with Sawtooth Mining and The North American Coal Corporation (“North American Coal”) during project development, Thacker Pass will be able to leverage over 100 years of sedimentary mining experience and one of the best safety records in the industry, which may help to further de-risk Project execution.

Sawtooth Mining has exclusive responsibility for the design, construction, operation, maintenance and all mining and mine closure services of the Thacker Pass surface mine which will supply all of Lithium Nevada’s lithium-bearing ore requirements. North American Coal, through its many subsidiaries, operates nine surface coal mines and provides services at twenty aggregates quarries in the United States, with annual total deliveries exceeding 70 million tonnes in 2018.      

The Mining Agreement is effective immediately and Sawtooth Mining will play an active role assisting Lithium Nevada with Thacker Pass’ permitting and development. In addition, Sawtooth Mining will provide Lithium Nevada i) US$3.5 million (of which, US$1 million has already been received) and ii) engineering services related primarily to mine design and permitting. During construction, Sawtooth Mining has agreed to fund up to US$50 million to procure all mobile mining equipment required for Phase 1 operations. Excluding these Sawtooth Mining investments, Lithium Nevada bears all costs of mining and mine closure.

TIC-The Industrial Company
Lithium Nevada has also entered into a design and build contract with TIC-The Industrial Company (“TIC”) a division of Kiewit Corporation (“Kiewit”), who has responsibility for the overall cost estimate in the definitive feasibility study as well as engineering design of plant, water supply infrastructure, electrical infrastructure, and general site works. Under the agreement, Lithium Nevada has the option to expand the agreement to include TIC as the prime contractor for construction of the plant. TIC and Kiewit have extensive experience building mines and processing facilities in Nevada and has access to an experienced workforce of over 20,000 employees.  

Process Engineering & Design

Process Testing Facility 
The Thacker Pass process optimizes and reconfigures several commercially-proven techniques in extractive metallurgy designed specifically for the processing of lithium bearing clays. To date, Lithium Nevada’s process testing facility located in Reno, Nevada has produced over 3,000 kg of high-quality lithium sulfate brine (“lithium sulfate”) from Thacker Pass ore. The process has been optimized by upgrading the ore through a wet attrition process followed by a hydrocyclone to remove coarse material with relatively low lithium content. The process test work has demonstrated an increase in lithium concentration by over 25% which results in reduced acid consumption per tonne of LCE.

In addition to optimizing acid consumption, the process testing facility has also generated tailings samples that are being used for stability and geochemical analysis, as well as feed samples to crystallizer vendors who will design the equipment and provide performance guarantees.

Crystallizer Vendors
Experienced crystallization vendors have been engaged to develop the design and cost estimate for process equipment to manufacture high-purity battery-quality lithium products from lithium sulfate, including lithium carbonate and lithium hydroxide.  A vendor has agreed to produce high-purity samples of lithium carbonate and lithium hydroxide from lithium sulfate produced at the process testing facility in Reno, Nevada. Lithium Nevada expects to send samples of Thacker Pass’ lithium products to potential customers and partners to confirm quality specifications.

Patent Application 
A patent application has been submitted to the United States Patent and Trademark Office to protect fundamental aspects of Lithium Nevada’s proprietary lithium extraction technology, which includes elements from the attrition process through to crystallization. 

Environmental & Social Responsibility

Environmental Responsibility
Lithium Nevada’s objective is to produce the most environmentally responsible lithium products. The nature of the deposit combined with the simple processing flowsheet and advanced pollution control technologies are expected to result in low water and energy requirements and minimal greenhouse gas emissions. The cogeneration facility produces a significant amount of carbon-free electricity that will be used to power the processing facilities. As a result, Lithium Nevada may be in a position to produce the first and only carbon-neutral lithium products.

Great Basin Sagebrush Restoration Fund
Consistent with the Company’s focus on environmental sustainability, Lithium Nevada and the University of Nevada, Reno Foundation (“UNR Foundation”) founded the Great Basin Sagebrush Restoration Fund (the “Fund”) in 2017. The Fund’s mission is to improve sagebrush habitat through cost-effective habitat rehabilitation methods. The research has produced numerous successes in seed enhancement technology, precision rehabilitation and genetics. The rehabilitation tools developed by the Fund have been recently deployed to assist a federal agency with the rehabilitation of federal lands impacted by recent large wildfires in Nevada. Several major mining companies and the BLM have recently made funding commitments, and the Fund is currently the largest sagebrush restoration fund in the United States.

Community Relations
Lithium Nevada is committed to being a good neighbor and has developed a community engagement strategy based on transparency, early engagement and frequent communication. Open houses have been held in Winnemucca and Orovada to communicate progress of Thacker Pass and collect feedback. Lithium Nevada is engaged with the local McDermitt Tribal government and has made commitments to provide skills training, jobs and economic opportunities. A project engagement agreement has been executed with the McDermitt Tribe to facilitate this process.

Feasibility Study 

Building on the results of the 2018 PFS, Lithium Americas expects to release an NI 43-101 compliant definitive feasibility study by mid-2020, which will incorporate detail on the status of the permitting process, outcomes of the 2018 exploration program, results generated by the process testing facility, updated project design, costs and economic results. The Company is targeting an initial phase (“Phase 1”) production capacity of 20,000 tonnes per annum of battery-quality LCE and is evaluating the production of lithium carbonate or lithium hydroxide depending on feedback from potential strategic partners and customers.  

Financing Strategy 

Lithium Americas intends to evaluate a variety of strategic financing options, including the possibility of a joint venture partner for the development of Phase 1 of Thacker Pass. The Company expects to begin a formal financing process in 2020.
