INTERNATIONAL LITHIUM FILES POSITIVE PEA OF MARIANA LITHIUM BRINE PROJECT, SALTA, ARGENTINA

International Lithium Corp.'s technical report "Preliminary Economic Assessment of the Mariana Lithium Brine Project" with an effective date of Nov. 15, 2018 (see the company's news release dated Dec. 6, 2018, for further details) is now filed under the company's profile on SEDAR. All figures are quoted in U.S. dollars.

PEA highlights:

• 25-year mine life producing 10,000 tonnes per year (TPY) lithium carbonate equivalent (LCE) plus 84,000 tonnes per year in sulphate of potash (SOP);
• The estimated capital exenditures and operating expenditures are for a conventional brine extraction facility, solar evaporation ponds and SOP processing with a level of accuracy of minus 30/plus 50 per cent.
• Capex estimated at $243-million (U.S.) for 25-year mine life;
• Net present value is $192-million (U.S.) after tax at 10-per-cent discount rate, internal rate of return of 20 per cent posttax;
• Project results remain positive, even with important negative variations on the driver variables, indicating project strength and resilience; thus, the PEA study indicates Mariana's proposed 10,000 TPY LCE concentrated brine and 84,000 TPY SOP fertilizer operation has the potential to generate strong economic returns.

The PEA was prepared by Advisian, a division of the WorleyParsons Group, for Mariana Lithium Corp. to provide a PEA of its Mariana lithium brine project in accordance with National Instrument 43-101 -- Standards of Disclosure for Mineral Projects. The PEA technical report assesses the potential economic viability of developing the 14 exploration licences (Minas) that cover the salar de Llullaillaco and surrounding area (23,560 hectares), for the purpose of extraction of lithium brine resources and processing of two products -- lithium carbonate equivalent and sulphate of potash. It should be noted that the company did not play any significant part in the production of the PEA report, and that the conclusions are therefore those of the consultants.

Current ownership of the Mariana project is through a joint venture company, Litio Minera Argentina SA, a private company registered in Argentina, owned 82.754 per cent by Ganfeng Lithium through its wholly owned subsidiary, Mariana Litihium Corp., and 17.246 per cent by ILC. In addition, ILC has an option to acquire another 10 per cent in the Mariana project through a back-in right.

Cautionary note

The preliminary economic assessment (PEA) is preliminary in nature, and it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. The PEA includes the results of an economic analysis of mineral resources, and mineral resources that are not mineral reserves do not have demonstrated economic viability.
