International Lithium Reports on 2019 Raleigh Lake UAV Magnetic Survey Results

Vancouver, British Columbia--(Newsfile Corp. - October 1, 2019) - International Lithium Corp. (TSXV: ILC) (the "Company" or "ILC") is pleased to announce the receipt of the final results from an unmanned aerial vehicle magnetometer ("UAV-MAG") survey designed to collect high-resolution magnetic field data over the Raleigh Lake project area. The resulting magnetic images confirm that a geologic body with elevated magnetic response, previously interpreted to be a gabbroic intrusive hosting the lithium bearing pegmatites, continues onto the adjacent group of claims acquired by ILC in 2018.

The 2019 UAV-MAG survey was conducted by Pioneer Aerial Surveys Ltd., a subsidiary of Global UAV Technologies Ltd. It covered a total of just under 500 line-kilometres using a 40 metre line spacing. The data were merged with the 2016 UAV-MAG survey which covered an additional 189 line-kilometres for almost 700 line-kilomtres of continuously profiled magnetic data recorded at an approximate ground clearance of 50 metres.

A map showing a gridded image of the merged data sets is given in Figure 1. The magnetic body interpreted to be the gabbroic host to the pegmatites is clearly visible in the eastern-central portion of the map. It measures approximately 3 kilometres by 1 kilometre which is comparable in size to the gabbroic rocks hosting the mineralized pegmatites at the Tanco mine.

The Two-mica granite is coarsely mapped in at the south-western extent of the survey area. It is thought to be the parental magma source for the spodumene bearing pegmatites at Raleigh Lake. It is located between four and six kilometres from the gabbro indicating that the gabbro is the optimal distance from the magmatic source body for fractionation to favor the crystallization of spodumene, a lithium rich mineral (Figure 2).

Several regional structures can be interpreted from the magnetic image shown in Figure 1. Some of these strucures transcend from the Two-mica granite to the Raleigh Lake gabbro. The structures cut the gabbro at its northern terminus, in the vicinity of the historic drilling, and in the central (thickest) portion of the body. No drill holes have tested the main gabbro body and all the historic drill holes at the terminus have intersected spodumene bearing pegmatites that dip gently southeasterly and flatten as they intrude the edge of the gabbro. There is a striking resemblence to the emplacement style of mineralized pegmatites at Tanco making the Raleigh Lake gabbro a highly prospective target.

The Company is planning to investigate these interpretations with a proposed 2,000 metre drill program, focusing on stepping out from the known mineralization both along strike to the southwest (toward the Two-mica granite) and down dip into the gabbroic body.

John Wisbey, Chairman and CEO of International Lithium Corp. stated, "We are delighted that the magnetometer survey at Raleigh Lake reinforces our belief that the geology is very promising. With an increasing awareness in Canada and the USA of the need for North American self sufficiency in lithium and other battery metals, we are also very pleased that the mineral rights remain wholly owned by International Lithium Corp. with no royalty or encumbrance over the property. The surrounding infrastructure is excellent with immediate access to the Trans Canada Highway, electricity and rail services to Lake Superior and the industrial heartland of North America. This remains a project that our board place a very high strategic value on."

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, now owned 85.8% by Ganfeng Lithium and 14.2% 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 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 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 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 and rare metal deposits. A key goal is to become a well funded company to turn that aspiration into reality.
