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 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 we stand to receive future payments from either a resource milestone being achieved or from a Net Smelter Royalty.

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 to be a clear and unstoppable momentum towards electric vehicles, solar power and electric battery storage, all of which contribute to rising demand for lithium. Rubidium is increasingly seen as a valuable critical metal that is strategic for high-precision clocks and for space technology. Copper has many historical uses, but demand is projected to be sharply higher as more data centres are required for AI. We have seen the clear and increasingly urgent wish by the USA, 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 for the next decade is to generate revenue for our shareholders from lithium and other battery metals, as well as rare metals, while also contributing to the creation of 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 separately announced that we regard Southern Africa as a key strategic target market for ILC and that we have applied for and hope to receive EPOs in Zimbabwe. We hope 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 continues to seek other opportunities:

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 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 our 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 company to turn our 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 2024, ILC continues to achieve sufficient inward cash flow to be able to make progress with its exploration projects.

With the increasing demand for high-tech rechargeable batteries used in electric vehicles, electrical storage, and 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 that have significant resource potential and solid strategic partners, ILC aims to be one of the preferred lithium and rare metals resource developers for investors and to continue building value for its shareholders for the rest of the 2020s, the decade of battery metals.

Nuvau Minerals Inc. (TSXV: NMC) has begun its minimum 1,500 m drill program aimed at testing continuity and extensions to the orogenic gold system discovered last month. The discovery was made with the first hole drilled of an inaugural gold-focused exploration program, in the footwall of the Bracemac-McLeod Mine approximately 200 m below surface. The follow-up program is being drilled immediately north east of this base metal mine, which was in production until mid 2022.

The Matagami Property is in the northern Abitibi Region of Quebec, one of the world’s most prolific gold endowed districts. This northern part of the Abitibi region includes Canada’s largest gold producing mine with the country’s largest gold mineral reserves: the Detour Lake Mine owned by Agnico Eagle Mines Limited. Hecla Mining Company’s Casa Berardi Mine, which has produced over 3 million ounces of gold, is located to the southwest of the Matagami Property (see Figure 1 below).

While the Abitibi’s first recorded gold discovery was 119 years ago in Rouyn-Noranda, the Matagami Property remains one of the largest areas in the region that has not been subject to a gold focused exploration program. Previous owners were concentrating on defining and developing multiple VMS deposits into multiple mines that produced extensive copper and zinc for more than 60 years. This was one of the primary opportunities Nuvau identified when it entered into the agreement to acquire the Property from Glencore. The Company recently began compiling gold related historic data, as well as launching several gold-focused initiatives (including till sampling) aimed at defining initial targets for drilling.

Nuvau’s current gold-focused exploration program has identified three initial priority targets:

1. Bracemac Footwall Discovery
2. Gold-in-Till Anomaly Target
3. Thunder Mine (1988) Target

The map below shows the location of these three targets (Figure 2). The vast majority of this 1,300 km² land pack remains open for gold exploration.

1. Bracemac Footwall Discovery

The recent discovery of gold mineralization in the footwall of the Bracemac Mine is located only 25 m from the access ramp of this permitted mine. The steeply dipping, strong shear zone structure with quartz veining mineralized with pyrite and locally visible gold was intersected at a depth of approximately 200 m. The visible gold was observed over approximately 0.5 m of core and assays are still pending on the discovery hole, BRCG-25-001.

Although located within the immediate footwall of the past-producing Bracemac-McLeod mine, the mineralized structure occurs in a late intrusive that truncated the mine host rock units (see Figure 3). The intrusive has seen very little drilling as the stratigraphy was not of interest for VMS exploration.

The follow up drill program is now underway to continue to step-out both up and down dip, and along strike, to test continuity of mineralization within the structural corridor as well as providing critical data on the dip and strike of the vein.

2. Gold-in-Till Anomaly Target

As part of Nuvau’s target generative exploration program, an overburden (till) drilling program was launched in 2023. This program resulted in the discovery of significant gold-in-till mineralization that was announced on March 4, 2025.

From the 2023 sonic drill program, hole PD-23-030s produced a notable gold grain anomaly detected at a depth of between 29.26 to 29.87 m in the overburden and featured more than 2,000 gold grains per 10 kg of material. In addition, a near-contiguous sample with 295 gold grains per 10 kg of material between 31.12 to 32.00 m was also encountered with the interval between consisting of a large locally derived boulder. Based on the almost pristine nature of the gold grains, and their close proximity to the bottom of the hole, the source is expected to be relatively close to this hole. (See images of gold grains below in Figure 5.)

To assist in defining targets in this area, a detailed drone MAG survey was completed. The limited rock outcrops were also mapped recently and together with the MAG data, a drill program is being designed for later this year. The objective of this drill program will be to gain a better understanding of the local geological structures and to test for the potential source of the extensive gold grains.

3. Thunder Mine (1988) Target

The Thunder Mine property was acquired by Nuvau in 2023 for its potential for both base metal and gold mineralization. In 1988, Thunderwood Exploration Ltd. drilled a series of holes as follow-up to a 1959 hole that intersected copper mineralization (see Figure 6).

This follow-up program identified multiple gold-bearing structures; however, no subsequent follow-up work was completed. Highlight intercepts from the available public domain report include the following:

• DT-14-88: 209.00 – 209.80 m (0.80 m) @ 26.40 g/t Au.
• DT-10-88: 205.00 – 206.00 m (1.00 m) @ 78.16 g/t Au.
• DT-18-88: 100.80 – 107.30 m (6.50 m) @ 1.55 g/t Au, incl.: 0.30 m @ 4.89 g/t Au.
• DT-19-88: 226.00 – 231.00 m (5.0 m) @ 2.27 g/t Au, Incl.: 0.50 m @ 10.39 g/t Au.
• DT-20-88: 136.80 – 137.10 m (0.30 m) @ 10.37 g/t Au and 204.50 – 205.00 m (0.50 m) @ 6.48 g/t Au.
• DT-21-88: 310.50 – 319.90 m (9.40 m) @ 4.02 g/t Au, incl.: 0.70 m @ 42.03 g/t Au and 0.70 m @ 7.30 g/t Au.
