International Lithium Corp. Begins Phase 3

Drilling at Raleigh Lake Lithium Project,

Ontario, Canada

Vancouver, British Columbia--(Newsfile Corp. - October 5, 2022) - International Lithium Corp. (TSXV:

ILC) (OTCQB: ILHMF) (FSE: IAH) (the "

Company

" or "

ILC

") is pleased to announce the start of Phase

3 of the 2022 diamond drilling campaign at the Raleigh Lake Lithium project near Ignace, Ontario,

Canada.

Further to Company's news release dated September 20, 2022; ILC has completed 6,251 metres core

drilling at the Raleigh Lake project in the first two phases of drilling in 2022. Phase 3 began on

September 28, 2022 with approximately 2,500 metres of proposed drilling.

The previous phase of drilling showed Lithium Oxide concentrations up to 3.62% over 6.46 metres and

Rubidium Oxide up to a grade of 1.38% over 5.9 metres. Phase 3 will include continued exploration and

infill drilling of Pegmatite 1 at Zone 1 (Figure 1) and testing new exploration targets at Zone 5, Zone 3

and Zone 6, defined by lithogeochemical surveys in 2021. The drilling objective at Zone 1 will be to trace

the high-grade core of Pegmatite 1 up-dip, closer to surface, and investigate the possibility of additional

pegmatites occurring below Pegmatite 1.

Two holes have already been completed at the Zone 1 pegmatite occurrences with drill hole RL22-45

intersecting 14 metres of pegmatite (Pegmatite 1) starting at 84 metres downhole*. The intersection

includes 4 metres of monomineralic microcline from 85.5 - 89.5m. The microcline associated with

Pegmatite 1 is known to contain highly anomalous rubidium concentrations and occurs in a distinct zone

within Pegmatite 1 that could warrant declaring the rubidium in the upcoming resource estimate as a

standalone commodity.

The second hole, RL22-46 was drilled approximately 75 metres west of RL22-45 and intersected

Pegmatite 1 over 10 metres from 89 metres downhole. Here Pegmatite 1 was encountered roughly 15

metres deeper than modelling would suggest. A second spodumene bearing pegmatite was intersected

from 108 - 110.5 metres downhole which aligns well with a deeper pegmatite vein encountered in drill

hole RL22-27 (Figure 2). This new discovery will be followed up immediately in the next few drill holes.

The drilling at Zone 1 continues to confirm the continuity of Pegmatite 1 and the near surface

prospectivity for additional lithium and rubidium bearing mineralization. The narrow pegmatites

intersected below Pegmatite 1 present an opportunity for the discovery of one or more pegmatites at

depth which could be open to expansion in all directions.

* All intervals reported here are downhole core lengths. Accurate true widths are unknown at this time but are estimated to be within 70-100% of

the reported intervals based on the geometry of the bodies and structural measurements on oriented core.

projection to its surface outcrop. Drill hole RL22-46 intersected Pegmatite 1 deeper than anticipated

giving it an almost horizontal orientation in this section. A second spodumene bearing pegmatite, that

appears to line up with a pegmatite vein intersected in RL22-27, was encountered at a deeper depth.

John Wisbey, Chairman and CEO of International Lithium Corp., commented:

We have already found some excellent grades of Lithium Oxide as high as 3.62% at Raleigh Lake and in

the first two phases of drilling this year we have done enough drilling to be on track for producing a

maiden resource estimate in 2022. As well as further exploration of the Raleigh Lake claims area, this

drilling is designed to give additional input into the size of such resource, and to give us and our

geological partners further confidence in the data, for example the size of a separate rubidium resource

in the microcline. Analysis of exact grades for this phase of drilling is expected to be finished after the

maiden resource estimate. Once again, we would stress that only 8% of the area of our claims has been

explored so far, and also stress again the excellent access to road and energy infrastructure in this

project.

About International Lithium Corp.

International Lithium Corp. believes that the world faces a significant turning point in the energy market's

dependence on oil and gas and in the governmental and public view of climate change. In addition, we

have seen the clear and increasingly urgent wish by the USA and Canada to safeguard their supplies of

critical battery metals and to become more self-sufficient. Our Canadian projects are strategic in that

respect.

Our key mission in the next decade is to make money for our shareholders from lithium and rare metals

while at the same time helping to create a greener, cleaner planet. This includes optimizing the value of

our existing projects in Canada and Ireland as well as finding, exploring and developing projects that

have the potential to become world class lithium and rare metal deposits.

A key goal has been to become a well-funded company to turn our aspirations into reality, and following

the disposal of the Mariana project in Argentina in 2021 and the Mavis Lake project in Canada in

January 2022, the Board of the Company considers that ILC is now well placed in that respect with a

strong net cash position.

The Company's interests in various projects now consists of the following, and in addition the Company

continues to seek other opportunities:

The Company's primary strategic focus at this point is on the Raleigh Lake lithium, rubidium and

caesium project in Canada and on identifying additional properties.

The Raleigh Lake project consists of 48,500 hectares (485 square kilometres) of mineral claims in

Ontario and is ILC's most significant project in Canada. The exploration results there so far, which are on

only about 8% of ILC's current claims, have shown significant quantities of rubidium and caesium in the

pegmatite as well as lithium. Raleigh Lake is 100% owned by ILC, is not subject to any encumbrances,

and is royalty free.

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 projects with significant resource potential

and with solid strategic partners, ILC aims to be one of the lithium and rare metals resource developers

of choice for investors and to continue to build value for its shareholders in the '20s, the decade of

battery metals.
