About International Lithium Corp.

While the world's politicians are currently divided on the future of the energy market's historic dependence on oil and gas and on "Net Zero", there seems a clear and unstoppable momentum towards electric vehicles and electric battery storage. We have also seen the clear and increasingly urgent wish by the USA and Canada and other major economies to safeguard their supplies of critical metals and to become more self-sufficient. Our Canadian projects, which contain lithium, rubidium and copper, are strategic in that respect.

Our key mission in the next decade is to make money for our shareholders from lithium and other battery metals and rare metals while at the same time playing our part in creating a greener, cleaner planet and less polluted cities. This includes optimizing the value of our existing projects in Canada as well as finding, exploring and developing projects that have the potential to become world class deposits. We have announced separately that we regard Zimbabwe as an important strategic target market for ILC, and that we have applied for and hope to receive EPOs there. We hope to be able to make announcements over the next few weeks and months.

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 and rubidium project and the Firesteel copper project in Canada and on obtaining EPOs and mineral claims in Zimbabwe.

The Raleigh Lake Project now consists of 32,900 hectares (329 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. A Preliminary Economic Assessment (PEA) was published for ILC's lithium at Raleigh Lake in December 2023, with detailed economic analysis of ILC's separate rubidium resource still to come. Raleigh Lake is 100% owned by ILC, is not subject to any encumbrances, and is royalty free. The project has excellent access to roads, rail and utilities.

A continuing goal has been to remain a well-funded company to turn our aspirations into reality, and following the disposal of the Mariana project in Argentina in 2021, the Mavis Lake project in Canada in January 2022, and the Avalonia project in 2024 (sale not completed yet), ILC has achieved sufficient inward cashflow to be able to make progress with its exploration projects.

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
