NEWS RELEASE

International Lithium Reports Drilling Underway at Mavis

Lithium Project, Ontario, Canada

Vancouver, B.C., January 23, 2018 : International Lithium Corp. (the “ Company” or

“ILC”) (TSX VENTURE: ILC) , in conjunction with its strategic partner , Pioneer

Resources Limited ( “Pioneer”) (ASX: PIO), is pleased to announce that drilling is

underway at the Mavis Lake Lithium Project in the province of Ontario, Canada.

Pioneer advises that drilling at Mavis Lake commenced late last week.

The 2018 winter program will comprise up to 1,200 metres of oriented NQ diamond core

drilling and will test for extensions to spodumene -bearing pegmatites intersected by the

joint venture (the “JV”) in the 2017 drilling program targeting the Fairservice (PEG006 or

Pegmatite 6) prospect (see ILC news release dated October 17, 2017).

Drill core logging and cutting for the first hole, MF18 -51 has been completed and all

samples have been submitted to the lab for analysis.

Pioneer, as operator of the project, will update ILC on the progress of drilling at Mavis

Lake as the program advances. Drilling is expected to take up to 30 days to complete.

As reported in the October 17, 2017 news release, each of the four 2017 holes drilled at

the Fairservice Prospect by the JV in 2017 intersected multiple spodumene -bearing

pegmatites of significant thickness*.

Key Intersections from the Pegmatite 6 Target Area*:

 MF17-39: 17.90 metres* at 1.47% lithium oxide (“Li2O”) from 80.00 metres;

 MF17-40: 12.85 metres at 1.16% Li2O from 80.05 metres;

 MF17-49: 26.30 metres at 1.70% Li2O from 111.9 metres

including 7.70 metres at 2.97% Li2O from 130.5 metres; and

 MF17-50: 16.55 metres at 1.45% Li2O from 74.55 metres

and 23.10 metres at 1.40% Li2O from 122.00 metres.

* All widths reported are drill core widths and have not been converted into true width.

True width is currently unknown. Appropriate rounding of Li2O values applied.

About the Mavis Lake Lithium Project

The Mavis Lake Project is situated 19 kilometres east of the town of Dryden, Ontario.

The Project is ideally situated in close vicinity to the Trans -Canada highway and railway

major transportation arteries linking larger cities such as Thunder Bay, Ontario, to the

southeast and Winnipeg, Manitoba, to the west.

The current drill program is wholly funded by Pioneer as part of its earn -in on the Mavis

Lake Project (see Company news release dated March 14, 2016).

The Mavis and Raleigh projects are under option to strategic partner Pioneer Resources

Limited (ASX: PIO) pursuant to which Pioneer can acquire up to a 51% interest in the

projects.

About International Lithium Corp.

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

robust financial support, and a strategic partner and keystone investor, Jiangxi Ganfeng

Lithium Co. Ltd., (“Ganfeng Lithium”) a leading China -based lithium product

manufacturer.

The Company’s primary focus is the 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, totaling 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 ventur e company, Litio Minera

Argentina S. A., a private company registered in Argentina, ownership of which will be

revised to 82.754% by Ganfeng Lithium and 17.246% by ILC in early 2018 in order to

reflect each party’s current JV interest . In addition, ILC has an option to acquire 10% in

the Mariana project through a back-in right.

Complementing the Company’s lithium brine project are three rare metals pegmatite

properties in Canada known as the Mavis, Raleigh, and Forgan projects, and the

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

The ownership of the Avalonia project is currently 55% GFL and 45% ILC. GFL have an

option to earn an additional 24% by either incurring CDN$10 million expenditures on

exploration activitie s or delivering a positive feasibility study on the project, at which

time the ownership will be 79% GFL and 21% ILC.

The Mavis and Raleigh projects are under option to strategic partner Pioneer Resources

Limited (ASX: PIO) pursuant to which Pioneer can a cquire up to a 51% interest in the

projects.

The Mavis, Raleigh and Forgan projects together form the basis of the Company’s

Upper Canada Lithium Pool designated to focus on acquiring numerous prospects with

previously reported high concentrations of lith ium in close proximity to existing

infrastructure.

With the increasing demand for high tech rechargeable batteries used in vehicle

propulsion technologies and portable electronics, lithium is paramount to tomorrow’s

“green-tech”, sustainable economy. By positioning itself with solid strategic partners and

acquiring high quality assets for the Energy rEVolution supply chain, ILC aims to be the

partner of choice for investors in green -tech and to continue to build value for its

shareholders.
