International Lithium Files Positive PEA of Mariana Lithium

Brine Project, Salta, Argentina

Vancouver, B.C. January 22, 201 9: International Lithium Corp. (the “ Company” or “ ILC”)

(TSXV: ILC) is pleased to announce th at the technical report “ Preliminary Economic

Assessment of the Mariana Lithium Brine Project,“ or “PEA” with an effective date of November

15, 2018, (see the Company’s news release dated December 6, 2018 for further details) is now

filed under the Company’s profile on SEDAR.

PEA Highlights:

 25-year mine life producing 10,000 tonnes per year ( “TPY”) Lithium Carbonate

Equivalent (“LCE”) plus 84,000 TPY Sulphate of Potash (“SOP”).

 The estimated CAPEX and OPEX are for a conventional brine extraction facility, solar

evaporation ponds and SOP processing with a level of accuracy of -30/+50%.

 CAPEX estimated at US $243 million for 25-year mine life.

 NPV = US $192 million after-tax at 10% discount rate, IRR = 20% post-tax.

 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 (“NI 43 -101”). The PEA

technical report assesses the potential economic viability of developing the 14 exploration

licenses (Minas), that cover the Salar de Llullaillaco (the Salar) 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. All figures are quoted in US

dollars. It should be noted that the Comapny 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 S. A., a private company registered in Argentina, owned 82.754% by Ganfeng Lithium

through its wholly-owned subsidiary, Mariana Litihium Corp. and 17.246% by ILC . In addition,

ILC has an option to acquire another 10% 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.

The information contained in this news release relating to the PEA has been compiled by

Advisian Americas, a division of the WorleyParsons Group. The information has been reviewed

and approved by Stanislaw Kotowski, P.Eng., M.Sc., of Advisian. Mr. Kotowski is a "Qualified

Person" as the term is defined in NI 43-101 and is independent of ILC. WorleyParsons has

reviewed and approved the presentation of the PEA information in this news release.

Afzaal Pirzada, P. Geo., a Qualified Person as defined by NI 43-101 and a consultant to the

About International Lithium Corp.

International Lithium Corp. has a significant portfolio of projects, strong management, and a

strategic partner and key investor, Jiangxi Ganfeng Lithium Co. Ltd., (“ Ganfeng Lithium ”) a

leading China-based lithium product manufacturer.

The Company’s primary strategic focus is now on the Mariana project in Arg entina and on the

Raleigh Lake project in Canada.

The Company has a strategic stake in the Mariana lithium -potash brine project located within

the renowned South American “Lithium Belt” that is the host to the vast majority of global lithium

resources, reserves and production. The Mariana project strategically encompasses an entire

mineral rich evaporite basin, tota lling 160 square kilometres that ranks as one of the more

prospective salars or ‘salt lakes’ in the region. Current ownership of the project is through a joint

venture company, Litio Minera Argentina S. A., a private company registered in Argentina,

owned 82.754% by Ganfeng Lithium and 17.246% by ILC . In addition, ILC has an option to

acquire 10% in the Mariana project through a back-in right.

The Raleigh Lake project, now consisting of 3,027 hectares of adjoining mineral claims in

Ontario, is now regarded by ILC management as ILC’s most significant project in Canada. It

is 100% owned by ILC, is not subject to any encumbrances, and is royalty free.

Complementing the Company’s lithium brine project at Mariana and rare metal pegmatite

property at Raleigh Lake, are interests in two other rare metal pegmatite properties in Ontario,

Canada known as the Mavis Lake and Forgan Lake projects, and the Av alonia project in

Ireland, which encompasses an extensive 50-km-long pegmatite belt.

The ownership of the Mavis Lake project is now 51% Pioneer Resources Limited (ASX:PIO,

“Pioneer”) and 49% ILC. In addition, ILC owns a 1.5% NSR on Mavis Lake. Pioneer has an

option to earn an additional 29% by sole -funding a further CAD $8.5 million expenditures of

exploration activities, at which time the ownership will be 80% Pioneer and 20% ILC.

The Forgan Lake project will, upon Ultra Lithium meeting its contractual requirements

pursuant to its agreement with ILC, become 100% owned by Ultra Lithium (TSXV: ULI), and

ILC will retain a 1.5% NSR on Forgan Lake.

The ownership of the Avalonia project is currently 55% Ganfeng Lithum and 45% ILC.

Ganfeng Lithium has an option to earn an additional 24% by either incurring CAD $10

million expenditures on exploration activities or delivering a positive feasibility study on the

project, at which time the ownership will be 79% Ganfeng Lithum and 21% ILC.

With the inc reasing demand for high tech rechargeable batteries used in electric vehicles

and electrical storage as well as portable electronics, lithium has been designated “the new

oil”, and is a key part of a “green tech”, sustainable economy. By positioning itself with solid

strategic partners and projects with significant resource potential, ILC aims to be one of the

lithium and battery metals resource developers of choice for investors and to continue to

build value for its shareholders.

International Lithium Co rp.’s mission is to find, explore and develop projects that have the

potential to become world class lithium, potash and rare metal deposits. A key goal is to

become a well funded company to turn that aspiration into reality.

On behalf of the Company,

John Wisbey
