Vancouver, British Columbia--(Newsfile Corp. - July 11, 2023) - International Lithium Corp. (TSXV: ILC) (OTCQB: ILHMF) (FSE: IAH) (the "Company" or "ILC") is pleased to announce that it will receive AUD$750,000 (approximately CAD$663,000 or USD$500,000) as payment for a milestone reached on the Mavis Lake lithium project.

Further to Company news release dated October 25, 2021 announcing the divestiture of the Mavis Lake project to Critical Resources Limited (ASX: CRR), ILC is now entitled to receive a payment of AUD$750,000. The payment represents ILC's 50% portion of the first AUD$1,500,000 payment made payable to the vendors of the project if certain milestones are reached. The other vendor is Essential Metals Limited (ASX: ESS, "ESS").

Under the agreement, milestone payments totalling AUD$3.0 million will be payable on the definition of a lithium resource as follows:

• AUD$1.5 million on definition of a mineral resource estimate exceeding 5 million tonnes with at least 50,000 tonnes of Li2O.
• A further AUD$ 1.5 million on definition of a resource exceeding 10 million tonnes with at least 100,000 tonnes of Li2O% or, in case both milestones are defined at the same time, AUD$3.0 million in total. ESS and ILC will share the proceeds equally.

On May 5, 2023, CRR announced a maiden inferred mineral resource estimate for the Mavis Lake project consisting of 8 million tonnes grading 1.07% Li2O indicating a Li2O content of 80,000 tonnes at a cut-off grade of 0.3%. According to CRR's news release, the mineral resource estimate is compliant with JORC Code 2012.

On July 3, 2023, CRR announced that extension drilling is underway at Mavis Lake with the goal to increase the size of the mineral resource, therefore, the board of ILC believes there is a good possibility that the second milestone could be reached in the next few months resulting in an additional AUD$750,000 payable to ILC.

Executive Comment

John Wisbey, Chairman and CEO of ILC, commented: We congratulate Critical Resources on these initial results at Mavis Lake near Dryden, Ontario, all currently in the inferred resource category. We wish them every success in progressing to the next level. Our sale has been a good win/win. Critical Resources are achieving good results there, while ILC has been able to focus on Raleigh Lake where we have also achieved good results with our own 43-101 compliant Maiden Resource estimates for lithium and rubidium announced on March 1, 2023. Raleigh Lake is near Ignace, Ontario with excellent infrastructure, and is about an hour's drive towards Thunder Bay and Lake Superior from Mavis Lake down the Trans-Canada highway.

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 and less polluted cities. 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. We have announced separately that we regard Zimbabwe as an important strategic target market for ILC, and we hope to be able to make announcements over the next few weeks and months.

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 Project's lithium and rubidium project in Canada and on identifying additional properties in Canada and Zimbabwe.

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. Drilling has so far been on less than 1,000 hectares of our claims. 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 energy 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.

On behalf of the Company,

John Wisbey
Chairman and CEO
