ILC Critical Minerals Ltd. Extends Option to

Buy Lepidico Mauritius Ltd, Which Owns 80%

of the Namibian Company That Owns a 100%

Interest in the Karibib Lithium, Rubidium and

Cesium Project

Vancouver, British Columbia--(Newsfile Corp. - January 26, 2026) - ILC CRITICAL MINERALS LTD.

(TSXV: ILC) (OTCQB: ILHMF) (FSE: IAH0) ("ILC" or the "Company") is pleased to announce that it has

extended its option to buy 100% of Lepidico (Mauritius) Ltd. ("Lepidico Mauritius") from Lepidico

(Canada) Inc. ("Lepidico Canada") until February 27, 2026.

Since the option and the related loan agreement were first announced on September 9, 2025, Lepidico

Chemicals Namibia (Pty) Ltd. ("LCN" or "Lepidico Namibia") has received, as announced on December

29, 2025, an adverse arbitration determination from the Singapore based SIAC in respect of LCN's

dispute about an offtake agreement concluded with Jiangxi Jinhui Lithium Co. Ltd. in China. Despite the

original offtake agreement in 2018 being under Ontario Law, and the arbitration being in Singapore, the

arbitration tribunal consisted of two Chinese professors resident and working in China, and one

Singaporean.

There have been and remain some quite complicated legal questions to address, and also there is the

need to obtain exchange and/or regulatory approval in Canada and Namibia. So an option extension

was necessary. In return for receiving that option extension, ILC has agreed to provide to Lepidico

additional working capital payments totaling a further CAD$145,000. Should the option to buy Lepidico

Mauritius be exercised these payments will be without recourse to Lepidico Canada. Should the option

not be exercised, these payments will be added to the secured loan and interest owed by Lepidico

Canada.

About ILC Critical Minerals Ltd.

ILC Critical Minerals Ltd., formerly 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 Karibib 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 minerals 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,

rubidium 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 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 exercise its option and 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. This showed, for the lithium only and not yet taking into account the

rubidium, a Post-tax NPV of CAD$342.9 million and a Post-tax IRR of 44.3% p.a. This was based on a

spodumene price of US$2,350 per tonne. As at January 23, 2026 the spot spodumene price was US$

2,214 per tonne. 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.
