Update on Economics of Raleigh Lake Project

in Ontario

Vancouver, British Columbia--(Newsfile Corp. - January 9, 2026) - International Lithium Corp. (TSXV:

ILC) (OTCQB: ILHMF) (FSE: IAH) ("ILC" or the "Company") is pleased to note the upturn in lithium prices

from their low in June 2025, and wishes to give guidance and clarification to the wider investor

community for what this means for ILC's Raleigh Lake project. The financial projections and assumptions

in this release are already in the public domain as they were included in the Company's previously

published disclosures.

Since June 30, 2025, the price of Lithium Carbonate, the main lithium benchmark, has risen from USD

8,535 per tonne to USD 19,747 on January 8, 2026, a rise of 131%, while the price of Spodumene

Concentrate containing 6% Lithium Oxide ("SC6") in the same period has risen from USD 630 to

USD1,800 per tonne, a rise of 185%. The source for these prices is @LithiumPriceBot on X. The rise in

SC6 has well outperformed even silver since June 2025. Obviously the low in June 2025 followed a very

difficult previous 2 ½ years for lithium prices. At the present exchange rate of USD=CAD 1.3880, that

means a SC6 price measured in CAD$ of CAD$2,498.40 per tonne.

When ILC published the technical report for its Preliminary Economic Assessment ("PEA") for Raleigh

Lake on January 18, 2024*, ILC's board and management had the foresight to request and publish some

sensitivity analysis of the results, as any NPV or IRR calculation is critically dependent on the commodity

sale price assumption. The relevant table in the Technical Report (Lithium only) is Table 22-6 shown

below, and the sensitivity to the SC6 price assumption at the time of the Technical Report on Raleigh

Lake was as per that table.

Interpolating this table linearly between the two numbers modelled in the PEA for the Spodumene SC6

price of CAD$ 2,100 per tonne and CAD$ 2,500 per tonne would mean that using as an input the spot

price on January 8, 2026, of CAD$ 2,498.40 per tonne the Net Present Value and Internal Rate of Return

for the lithium only at the Raleigh Lake project calculated in the same way as in the table below and

subject to the same disclaimers would give the following numbers using a discount rate of 8% p.a.:

NPV (CAD$)

223.1 million

IRR % p.a.

We believe that these are helpful numbers to publish now to put the lithium price recovery into context as

far as ILC's Raleigh Lake project is concerned. We would stress that the medium term price assumption

for a commodity sale price is generally not the same as the current spot price. We have not considered

or consulted with the consultants who wrote the report on what the appropriate medium term price might

be as at today. We would also stress that prices can go down as well as up, and that costs may have

varied since the PEA was completed in January 2024. It should be noted that the Maiden Resource

Estimate at Raleigh Lake in April 2023 also quantified a rubidium resource there. The PEA was for

lithium only, and did not include sales of rubidium or cesium or other minerals.

Separately, we can report that ILC has filed for the appropriate permissions to turn various mining claims

at Raleigh Lake into a mining lease, and this process is now well underway. We are in the process of

planning the work we wish to carry out this year at Raleigh Lake given the improvement in the

economics. This includes attempting to complete a PEA for the rubidium there, despite the challenges of

robust pricing assumptions for rubidium chemicals.

About International Lithium Corp.

International Lithium Corp. has exploration activities in Ontario, Canada, with intentions to expand into

Southern Africa. It has projects at various stages, ranging from Definitive Feasibility Study at Rubicon in

Namibia (note that ILC currently has an option only and is treating this as historic information at this point

and not a current resource for ILC) to Preliminary Economic Assessment at Raleigh Lake to Pre-Drilling

at Wolf Ridge. The primary target metals in Canada are lithium, rubidium and copper. There are three

projects (two in Ontario and one in Ireland) in which ILC has sold its share, but where the Company

stands to receive future payments from either a resource milestone being achieved or from a Net

Smelter Royalty. In Namibia the Karibib project contains lithium, rubidium and cesium.

While the world's politicians remain divided on the future of the energy market's historic dependence on

oil and gas and on "Net Zero", there is in any scenario an ever-increasing and significant demand for

electricity driven by AI and data centres, and by a likely unstoppable momentum towards electric vehicles

and grid-scale electricity storage. All of these contribute to rising demand for lithium, copper, and other

metals. Rubidium is also a critical metal, strategic for high-precision clocks, space technology, and

improving the performance of certain types of solar panels. ILC has seen the politically driven,

increasingly urgent push by the USA, Canada, the EU, and other major economies to safeguard their

supplies of critical metals and to become more self-sufficient. The Company's Canadian and Southern

African projects, which contain lithium, rubidium, cesium and copper, are strategic in this regard.

The Company's key mission for the next decade is to generate revenue for its shareholders from lithium

and other critical minerals while also contributing to the creation of a greener, cleaner planet and less

polluted cities.

This includes optimizing the value of ILC's existing projects in Canada as well as finding, exploring and

developing projects that have the potential to become world-class deposits. The Company announced

that it regards Southern Africa as a key strategic target market and, in addition to Namibia, it has

applied for and hopes to receive EPOs in Zimbabwe. The board hopes to make further announcements

on the portfolio developments over the next few weeks and months.

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

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

and rubidium, and the Firesteel copper project in Canada, as well as obtaining EPOs and mineral

claims in Zimbabwe. The Karibib projects in Namibia, including further development of the EPL there,

will be a high priority if ILC decides to remain involved.

The Raleigh Lake Project now encompasses 32,900 hectares (329 square kilometres) of mineral claims

in Ontario and represents ILC's most significant project in Canada. To date, drilling has occurred on less

than 1,000 hectares of the Company's claims. A Preliminary Economic Assessment was published for

ILC's lithium at Raleigh Lake in December 2023, with a detailed economic analysis of ILC's separate

rubidium resource still pending. Raleigh Lake is 100% owned by ILC, free from any encumbrances and

royalties. The Raleigh Lake Project boasts excellent access to roads, rail, and utilities.

A continuing goal has been to remain a well-funded, strategically run company that turns ILC's

aspirations into reality. Following the disposal of the Mariana project in Argentina in 2021, the Mavis

Lake project in Canada in 2022, and the Avalonia project in 2025, ILC has continued to generate

sufficient cash inflows to advance its exploration projects.

With increasing demand for high-tech rechargeable batteries used in electric vehicles, energy storage,

and portable electronics, lithium has been dubbed "the new oil". It is a key part of a green, sustainable

economy. By positioning itself on projects with significant resource potential and solid strategic partners,

ILC aims to become a preferred lithium and critical minerals resource developer for investors and to

continue building value for its shareholders throughout the 2020s, the decade of battery metals.

On behalf of the Company,

John Wisbey
