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 Ltd. (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 venture 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 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 Ltd. (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 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.
