Highlights
- 31 new LCT pegmatites discovered to the east of the Mavis Lake Main Zone, including multiple spodumene-bearing pegmatites1.
- Discoveries reinforced with the extension of multiple mapped outcrops – increasing the known outcrop of spodumene-bearing pegmatites up to 250m along strike.
- 83 grab and channel samples collected across the broader Mavis Lake Project Area.
- Muscovite samples gathered for Laser Induced Breakdown Spectroscopy (LIBS) analysis, enhancing knowledge on the fractionation trends.
- Advanced planning completed for the positioning of drill pad locations targeting known spodumene-bearing pegmatites within the Northern Prospects (Gullwing and Tot).
- Planning and permits in place to undertake mechanical stripping and channel sampling of the Tot Pegmatite.
The discoveries, made just weeks into the Company’s 2024 Summer Field Exploration Campaign, highlight the outstanding potential of the Mavis Lake Project to yield further significant lithium discoveries. The exciting results also provide further validation of the JORC compliant Exploration Target announced last week for Mavis Lake (see ASX announcement, 22 May 2024).
Detailed Field Work Delivers Outstanding Initial Results
A field work program comprising prospecting, mapping and sampling began in early May, designed to identify new spodumene-bearing pegmatites, determine fractionation trends at the Northern Prospects and conduct drill pad reconnaissance throughout the Mavis Lake Lithium Project.
A total of 83 samples were collected from pegmatite outcrops across the broader Project Area. A total of 31 new pegmatite discoveries have been made. The discoveries include a ~250m extension of a known spodumene-bearing pegmatite (Pegmatite 20) and 100m extension of the Main Zone spodumene-bearing pegmatite cluster (Pegmatites 7 and 24). Samples have been prepared and will be dispatched to an independent analytical laboratory in the coming weeks, with full results expected in July/August 2024.
Critical Resources Managing Director, Alex Cheeseman said:
“It’s great to see field teams directly following up our Exploration Target and making further significant discoveries at Mavis Lake at the start of the new field season. The field program has already increased our confidence in our ability to deliver on the recently published Exploration Target, paving the way for drill testing a number of high-quality targets. We look forward to continuing our dual-track strategy of targeting resource growth while progressing our project development and permitting workstreams for Mavis Lake.”
Discoveries at Main Zone and East of Main Zone
Field crews spent three weeks prospecting across the Mavis Lake Project Area, resulting in the discovery of 31 new LCT-Type pegmatites. Most of these discoveries are located proximal to and to the east of the Main Zone.
Notable finds include a ~250-metre extension of spodumene-bearing pegmatite 20, a ~100-metre extension of spodumene-bearing pegmatites 7 and 24, and the identification of spodumene- bearing pegmatite 25.

Overview
International Lithium (TSXV:ILC,OTC:ILHMF,FRA:IAH,OTCQB:ILHMF) is a Canada-based mineral exploration company focused on the discovery and development of lithium and other critical metals essential for the transition to a cleaner, greener planet. With a portfolio of projects located in mining-friendly jurisdictions, the company’s primary objective is to build shareholder value by advancing its key assets towards production while expanding its presence in emerging critical metals regions.
International Lithium's flagship asset is the 100 percent owned Raleigh Lake lithium and rubidium project in Ontario. A preliminary economic assessment (PEA) for the Raleigh Lake project, completed in December 2023, demonstrated strong project economics and significant resource growth potential, including an annual after-tax cash flow of C$634 million, NPV of C$342.9 million and IRR of 44.3 percent, with a nine-year mine life and project duration of 11 years. This assessment did not yet include rubidium, which represents significant additional potential pending further market analysis.
Complementing its lithium focus, the company is advancing the Firesteel copper-cobalt project in northwestern Ontario, targeting high-grade base metal mineralization to further diversify its critical metals exposure.
In addition to its Canadian projects, International Lithium is positioning for further international growth with a strategic focus on Southern Africa. It has applied for exclusive prospecting orders (EPOs) in Zimbabwe, one of the world's most prospective regions for hard rock lithium exploration.

Key Projects
Raleigh Lake
The Raleigh Lake project is ILC’s flagship asset, located approximately 25 kilometres west of Ignace, Ontario. The project covers a contiguous land package of 32,900 hectares and is 100 percent owned by the company. Raleigh Lake benefits from excellent infrastructure access, situated near the Trans-Canada Highway, a Canadian Pacific Railway line, and existing natural gas and hydroelectric infrastructure.
Major public infrastructure relative to the Raleigh Lake project
Raleigh Lake is notable for its dual potential to host both lithium and rubidium mineralization. The lithium is found primarily in spodumene-bearing pegmatites, while rubidium is associated with microcline-rich zones of the same lithium-cesium-tantalum pegmatite system. In 2023, International Lithium published a maiden mineral resource estimate (MRE) that delineated significant resources for both lithium and rubidium using separate cutoff criteria.
For lithium (Li₂O), the project hosts a measured and indicated resource of 5.88 Mt grading 0.79 percent Li₂O, and an inferred resource of 2.07 Mt grading 0.77 percent Li₂O, primarily within pegmatite #1. This lithium resource forms the basis of the company’s PEA, which demonstrated robust project economics with an after-tax NPV (8 percent) of C$342.9 million and an IRR of 44.3 percent.
The rubidium component, though not included in the PEA due to current market constraints, represents an additional potential value stream. The company has reported a measured and indicated resource of 133,000 tons at 6,163 ppm rubidium (0.67 percent Rb₂O) and an inferred resource of 123,000 tons at 4,224 ppm rubidium (0.46 percent Rb₂O), using a 4,000 ppm cutoff. The rubidium zones are found in association with potassic feldspar, offering a potentially recoverable byproduct pending further market and technical evaluation.
Given the project’s strong infrastructure position, mineral endowment, and defined development path, Raleigh Lake represents a compelling advanced-stage opportunity in North America's lithium supply chain. International Lithium is continuing infill and expansion drilling, environmental baseline studies, and metallurgical testing to support project advancement toward pre-feasibility.
Firesteel Project
The Firesteel project is an early-stage copper-cobalt exploration property located in northwestern Ontario, approximately 10 km west of Upsala along Highway 17. Spanning a 16-km corridor to the Firesteel River, the property lies within a geologically favorable region characterized by Archean metavolcanic and metasedimentary rocks, which are prospective for volcanogenic massive sulphide (VMS) and sedimentary copper systems.
International Lithium completed the acquisition of a 90 percent interest in the Firesteel project in May 2024, aiming to diversify its critical metals portfolio beyond lithium. Historical sampling on the property has returned encouraging results, including copper assays up to 2.6 percent and cobalt values reaching 309 ppm. Notably, the "Roadside 1" occurrence features semi-massive sulphide mineralization comprising pyrite, pyrrhotite, chalcopyrite and bornite. These findings suggest the presence of a highly metamorphosed VMS or sedimentary copper system, potentially up to 20 meters wide and extending over a kilometer in length.
The project's proximity to major infrastructure, including highways and railways, coupled with its strategic location near the company's Raleigh Lake project, enhances its development potential. International Lithium plans to conduct systematic exploration, including geochemical sampling and geophysical surveys, to refine targets for future drilling campaigns.
Wolf Ridge Project
Wolf Ridge is a 5,700-hectare grassroots lithium project located 20 km southwest of Upsala and near ILC’s Firesteel copper claims. The area benefits from excellent infrastructure, including proximity to Highway 17, power, and road access.
The project was highlighted by the Ontario Geological Survey (2021–2022) for its standout lake sediment anomalies - among the highest lithium values in the region - indicating strong potential for LCT pegmatite mineralization.

Southern Africa Exploration Initiative
Southern Africa is recognized as a prospective region for hard rock lithium, and International Lithium’s strategic focus reflects a proactive move to establish a presence in this emerging jurisdiction.
As part of its strategy to expand its critical metals footprint, International Lithium has applied for Exclusive Prospecting Orders (EPOs) over several prospective areas in Zimbabwe. The targeted regions are known for hosting spodumene, lepidolite and petalite-bearing pegmatites, indicating potential for significant lithium resources.
Although the EPO applications are still pending approval, the company has already conducted initial due diligence, including geological reviews and desktop studies, to prioritize exploration targets once access is granted. Zimbabwe’s growing importance as a global lithium supplier, combined with favorable mining policies, offers a compelling backdrop for the company's expansion efforts. International Lithium intends to leverage its technical expertise and exploration experience to quickly evaluate and develop these opportunities upon receiving the necessary permits
