NEWS RELEASE

International Lithium Reports Drilling Commences at the

Avalonia Lithium JV, Ireland

Vancouver, B.C., May 14, 2018: International Lithium Corp. (the “ Company” or “ ILC”)

(TSX VENTURE: ILC) is pleased to announce , together with joint venture partner GFL

International Co. Ltd ., a subsidiary of Jiangxi Ganfeng Lithium Co. Ltd. (“Ganfeng

Lithium” or “GFL” ) the commencement of drilling at the Avalonia lithium pegmatite

project (“Avalonia JV”) in Ireland, a joint venture between the two companies.

As announced on January 11, 2018, ILC and Ganfeng Lithium approved a Euro

705,000 (approximately CAD $1 million) budget for the 2018 calendar year for the

Avalonia JV.

The 2018 d rilling will take place in two phases with a total of approximately 2,000

metres drilling at the Moylisha target area. The first phase which has already started ,

will focus on drilling in proximity to the previ ous drilling from 1976 and 2013 to aid in the

interpretation of geophysical work conducted in 2017. The second phase of drilling will

target previously undrilled areas at Moylisha and any new targets identified during the

first phase. A total of 25 sites have been permitte d for drilling although not all will be

drilled.

Each phase of drilling is expected to take about six weeks (totalling twelve weeks for the

entire programme).

Moylisha is believed to be a highly prospective target area. It has extensive boulder

trains of spodumene -bearing pegmatite assaying up to 4.59% Li2O* on grab samples

which have yet to be traced back to source.

* Previously reported grab sample in a Company news release dated January 31, 2012.

Grab samples are by definit ion selective and are unlikely to represent average grades

on the property.

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 CAD$10 million expenditures on

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

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

About International Lithium Corp.

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

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 venture company, Litio Minera

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

revised shortly to 82.754% by Ganfeng Lithium and 17.246% by ILC 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 th e 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 CAD$10 million expenditures on

exploration activities 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 acquire 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 lithium in close proximity to existing

infrastructure.

With the increasing demand for hi gh 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

3

shareholders.
