International Lithium Acquires Further Mineral Rights at Raleigh Lake, Ontario and Agrees to Sell Forgan Lake Project

Vancouver, September 10, 2018 - International Lithium Corp. (the "Company" or "ILC") (TSXV: ILC) announces that it has reached an agreement (the "Raleigh Agreement") to acquire from a third party 55 additional claims adjacent to its Raleigh Lake Project in Ontario. This new acquisition will increase the total size of the Raleigh Lake property to 1,976 hectares, or approximately double the original size. On August 29, 2018, the Company announced that, as part of a wider agreement with Pioneer Resources Ltd. (ASX: PIO) ("Pioneer"), all the rights, title and interest in the Raleigh Lake property were being returned to the Company, with no further obligations by ILC.

Pursuant to the Raleigh Agreement, the Company will pay the vendor a combination of cash and 400,000 ILC common shares to acquire a 100% interest in the new Raleigh Lake claims, with no further encumbrances or royalties.

A map of the enlarged Raleigh Lake claim area is shown below, and displays both existing claims (blue) and new claims (green). The property has a convenient location in a relatively unpopulated area, and benefits from a close proximity to the major N17 Trans-Canada Highway.

The Company also announces that it has reached an agreement (the "Forgan Agreement") to sell its Forgan Lake mineral rights to Ultra Lithium Inc. (TSXV: ULI) ("Ultra Lithium"). The Forgan Lake property is comprised of one legacy claim, TB4244103 (converted in 18 cell claims and two boundary claims as of April 10, 2018 by the Ontario Ministry of Northern Development and Mines). The consideration to be paid to ILC is a combination of cash and shares totaling an aggregate CAD$200,000, payable over two years. The sale is subject to Ultra Lithium spending CAD$500,000 on development expenditures before September 2020, failing which the property will revert to ILC. In addition, as part of the consideration, ILC will receive a 1.5% Net Smelter Returns Royalty on future production, both from Forgan Lake and from an adjoining property owned by Ultra Lithium.

John Wisbey, Chairman & CEO of the Company said, "Raleigh Lake is the property in Ontario that we were most excited about. We have not only got back all our rights to this asset, but we have now been able to acquire further rights that almost double the area of our claims in the Raleigh Lake area that we believe maximizes the potential of the mineralization that exists on the claims. I am very pleased that we have been able to move at speed like this to achieve a strategic goal in Canada. We will be conducting some drilling in the next few months with the goal of validating our hopes for the potential of Raleigh Lake. We believe there is considerable potential, although until we have more drilling results to complement those drilling results from earlier years and the magnetic drone survey carried out in 2016, there is always the risk that we may be disappointed.

Our property at Forgan Lake was not large enough to be strategic to us, but it complemented Ultra Lithium's existing portfolio in the area, so the disposal was a win-win."

Anthony Kovacs, COO of the Company added, "ILC's original claims on Raleigh Lake were drilled for tantalum by a previous operator. This work identified shallow dipping to almost flat lying tantalum, lithium and rubidium mineralization in drill core, later confirmed by a second operator in 2010, covering a surficial area of over 300 metres by 600 metres. Although the lithium content was appreciable, no further work was conducted until after ILC acquired the property in 2016 and a magnetic drone survey was carried out. Our expectation is that this mineralization extends into the newly acquired claims. With this in mind, we will be planning for some exploratory drilling over the next few months, both on our existing claims and on the new claims."

The Raleigh Agreement and the Forgan Agreement are subject to approval of the TSX Venture Exchange. Any shares issued will be subject to a hold period of four months from the date of issue.

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 Argentina 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, totalling 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 1,976 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 Avalonia project in Ireland, which encompasses an extensive 50-km-long pegmatite belt.

The ownership of the Mavis Lake project is now 51% Pioneer Resources Ltd. (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 increasing 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 Corp.'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
Chairman and CEO
