In mid-November 2023, Jindalee Lithium Limited (Jindalee, the Company) announced results from beneficiation of composite samples from the Company’s 100% owned McDermitt Lithium Project located in Oregon, USA, and noted that acid leaching of beneficiated samples was underway1.
- Excellent lithium (Li) extraction rates from acid leaching of beneficiated McDermitt ore
- Li extraction from composite samples averaged 93% (250µm) and 94% (75µm)
- Li extraction from all units exceeds 98% with higher acid additions
- Leaching of a bulk sample is underway to enable downstream testwork
- Samples have been shipped to POSCO for parallel leach testwork
Samples of ore were beneficiated with a cut-size of 250-micron (µm). Material passing was either leached directly (“250µm leach feed”) or ground further so that all passed 75µm (“75µm feed”).
Jindalee is pleased to advise that initial results from acid leaching of the beneficiated samples have been received, with extremely high lithium extraction rates recorded from both the 250µm and 75µm leach feeds using 500kg sulphuric acid per tonne of leach feed. The 250µm leach feed was also leached with a higher strength acid (850 kg/t leach feed) and returned exceptional extraction rates (>98.5%) for all units (Table 1).
Table 1 – Maximum Lithium Extraction at variable feed sizes and acid strengths - Units 4, 6, 8 and 10 (* calculated)
The leach testwork extended for up to four hours with most of the Li extraction occurring in the first hour. Optimised lithium extraction and acid addition rates will be incorporated into the Pre-Feasibility Study (PFS).
Leaching of a bulk composite has commenced to provide lithium in solution for downstream testwork. Beneficiated samples (250µm) have also recently been shipped to POSCO Holdings (NYSE: PKX) (POSCO) for testwork, pursuant to the Memorandum of Understanding signed with POSCO in February 20234.
Discussion
In July 2023 Jindalee shipped approximately 700kg of drill core to Hazen (Colorado, USA) for metallurgical testing, with this testwork being managed by global engineering, procurement, construction and maintenance (EPCM) company Fluor Corporation (Fluor). The core samples were selected from Units 4, 6, 8 and 10 within the Indicated portion of conceptual Pit Shell 6 (nominal 43 years); these units carry elevated lithium grades and selective mining of these units has the potential to deliver significantly higher-grade material (when compared to the Mineral Resource Estimate average grade) for processing (Figure 1) (Table 2)2.
Figure 1 – Schematic Section C-C’ with completed drilling, simplified geology and conceptual Pit Shell 6 (nominal 43 years). (Note: lateral projection onto section plane and 3x vertical exaggeration may cause distortion)
Head assays for these samples were announced in October 20233 with Units 4, 6, 8 and 10 averaging 1,790 ppm Li, 34% higher than the average McDermitt Mineral Resource grade (1,340 ppm Li)2. Results from attrition scrubbing (beneficiation) of a composite sample of McDermitt ore (250µm cut-size) were announced mid- November 2023, recording 92.0% Li recovery with 25.3% mass rejection and the lithium grade to leach increasing to 2,107 ppm Li1.
The acid leaching testwork now being reported was conducted on both 250µm and 75µm leach feed sizes using 500 kg/t (and 850 kg/t for 250µm leach feed). A composite sample (representing a nominal life-of-mine average feed) was also tested using the two leach feed sizes, recording very high lithium extraction rates using 500 kg/t. Lithium extraction from the coarser (250µm) leach feed was 92.9% and compares favourably with the extraction rate (94.0%) achieved from the finer (75µm) leach feed (Table 1).
Next Steps
Acid leaching of a bulk composite sample is currently underway to provide lithium in solution for downstream work. Results from this testwork will feed into the PFS which is expected to be completed mid-2024.
Samples from Units 4, 6, 8 and 10 have been beneficiated (250µm) and shipped to POSCO for parallel leach testwork, pursuant to the Memorandum of Understanding signed with POSCO.

Investor Insight
With compelling economic metrics demonstrated through its new prefeasibility study, Jindalee Lithium’s McDermitt Project presents a strong case for investors to gain exposure to this critical mineral and participate in the global clean energy transition.
Overview
Jindalee Lithium (ASX:JLL,OTCQX:JNDAF) is an Australia-based pure-play US lithium company focused exclusively on its 100-percent-owned McDermitt Lithium Project, currently one of the largest lithium deposits in the US, boasting a resource of 21.5 million tons (Mt) of lithium carbonate equivalent (LCE).
Backed by a newly released (November 2024) prefeasibility study (PFS) demonstrating very compelling economics, the McDermitt Project is poised to play a crucial role in meeting North America’s growing lithium demand for the lucrative battery value chain.
As the US continues to transition to energy independence, demand for lithium is expected to exponentially increase. Jindalee’s McDermitt Project, located in southeast Oregon, is a game-changer for North American lithium supply, critical for meeting the demands of the fast-growing electric vehicle, energy storage and defense sectors.
McDermitt also stands to significantly benefit from the US government’s policies and incentives to boost domestic supply of critical resources. In fact, in a move that signifies the US government's support of the McDermitt Lithium Project, the US Department of Energy's Ames National Laboratory signed a Cooperative Research and Development Agreement with Jindalee's subsidiary HiTech Minerals to develop cutting-edge extraction methods for the McDermitt Project. The Ames National Laboratory spearheads the DOE's Critical Materials Innovation Hub.
Key milestones in the US lithium resource space also provide significant insights into the future prospects for Jindalee’s project. Lithium Americas (TSX:LAC), for instance, has received a total of US$945 million investment from General Motors, which will fund the development, construction and operation of the Thacker Pass project in Humboldt County, Nevada. In October 2024 LAC closed a $2.3 billion loan from the US Department of Energy and in April 2025 announced the Final Investment Decision for Thacker Pass following a $250 million investment from Orion Resource Partners.
Another lithium resource developer in Nevada, Australia-based Ioneer (ASX:INR) has closed a US$996 million loan guarantee from the US Department of Energy to finance the development of its flagship Rhyolite Ridge lithium-boron project.
The US government has taken further action to bolster domestic critical mineral production. On 20 March 2025, President Trump issued a significant executive order titled "Immediate Measures to Increase American Mineral Production", underscoring the urgency and strategic imperative of increasing domestic supply chains for critical minerals. This order builds on previous initiatives by fast-tracking the permitting processes, prioritizing access to mineral-rich federal lands, clarifying regulatory frameworks, and mobilizing substantial financial resources – including Defense Production Act (DPA) funds – towards domestic mineral projects.
As one of the largest lithium resources in the US and situated on federal lands, Jindalee’s McDermitt Lithium Project stands to potentially benefit from these accelerated permitting processes and enhanced government support mechanisms. The clear commitment demonstrated by the US administration highlights the critical strategic advantage of domestically located mineral assets such as McDermitt, reinforcing its importance in securing robust domestic supply chains, essential for energy security
These are just a few examples of current market dynamics that point to a rapidly accelerating lithium resource development in the US.
An experienced management team, with the right blend of experience and expertise in geology, corporate administration and international finance, leads Jindalee to fully capitalize on the potential of its assets.
Company Highlights
- Jindalee Lithium is focused on its wholly owned flagship McDermitt Lithium Project, one of the largest lithium deposits in the US.
- McDermitt’s new prefeasibility study shows strong project economics, including a US$3.23 post-tax NPV8 based on the first 40 years of a 63 year-year mine life.
- Jindalee is committed to strengthening the North American critical minerals supply chain by reducing US reliance on foreign lithium, thereby enhancing energy security.
- The company’s wholly owned US subsidiary HiTech Minerals Inc, has executed a strategic Cooperative Research and Development Agreement (CRADA) with Ames National Laboratory, which leads the US Department of Energy’s (DOE) Critical Materials Innovation (CMI) Hub.
- The company’s McDermitt deposit is sediment-hosted, an emerging style of lithium deposit with the potential to be a large scale, long-life, low-cost source of lithium.
- Ideally positioned to benefit from US administration’s push to increased domestic mineral production via permitting reformed increased funding.
- An experienced management team leads Jindalee towards capitalizing on the potential of its assets.
Key Project
McDermitt Lithium Project Economics
The economic metrics revealed in the PFS paint a compelling picture of the McDermitt Lithium Project's potential:
Production Capacity: The Project is set to produce 1.8 Mt of battery-grade lithium carbonate over its first 40 years, with an annual output forecast of 47,500 tons per annum (tpa) in the initial 10 years, tapering to 44,300 tpa over the first 40 years.
Financial Metrics: The Project boasts a net present value (NPV) of US$3.23 billion at an 8 percent discount rate, with an internal rate of return (IRR) of 17.9 percent. These figures underscore the Project’s strong economic viability.
Payback Period: Investors can expect a payback period of less than five years, a relatively short timeframe for a project of this magnitude.
Break-even Price: The break-even NPV price is approximately US$14,600/t of lithium carbonate, providing a buffer against market fluctuations.
The PFS estimates a total project cost of US$3.02 billion, which includes a prudent 21 percent contingency margin. This substantial investment is balanced by impressive profitability projections, including an EBITDA margin of 66 percent generating post-tax free cash flow of US$6.6 billion during the first decade of operations. With a pre-tax net operating cashflow margin of 17 percent at current spot prices, McDermitt shows strong cash generation potential.
These financial indicators suggest that McDermitt is not only economically viable but potentially highly profitable, positioning it as an attractive prospect for investors and strategic partners alike.
Project Overview
The McDermitt Project is located in Malheur County on the Oregon-Nevada border and is approximately 35 kilometres west of the town of McDermitt. The 100-percent-owned asset covers 54.6 square kilometres of claims at the northern end of the McDermitt volcanic caldera.
The Project is characterized by its unique sedimentary lithium deposits, primarily composed of lithium-bearing clays, a geological formation that sets McDermitt apart from many other lithium projects worldwide. This sedimentary nature of the deposit offers several advantages:
- Consistent grade distribution throughout the ore body
- Potential for large-scale, low-cost mining operations
- Amenability to environmentally friendly extraction methods
The lithium-rich clays at McDermitt are part of a broader geological context that includes volcanic tuffs and sedimentary rocks. This geological setting is indicative of a complex depositional history, which has resulted in the concentration of lithium in economically viable quantities.
The 2023 mineral resources estimate (MRE) for the McDermitt Project contains a combined indicated and inferred mineral resource inventory of 3 billion tons at 1,340 parts per million (ppm) lithium for a total of 21.5 Mt LCE at 1,000 ppm cut-off grade.
Project Highlights:
- Rare Sediment-hosted Lithium Deposits: The McDermitt asset supports low-cost mining operations due to its flat-lying sediments. This type of lithium deposit is amenable to low-cost mining operations, while still producing excellent metallurgical results.
- A 62 percent resource increase in early 2023: Compilation of the 2022 drilling results saw the estimated indicated and inferred resources at McDermitt increase to 3 billion tons at 1,340 ppm lithium, a 62 percent increase in contained lithium.
- Fluor recommended processing route: In March 2023, US engineering group Fluor reviewed all testwork undertaken at McDermitt and recommended beneficiation and acid leaching as the optimal processing route.
- Battery-grade lithium carbonate successfully produced in July 2024: The production is an important milestone validating all steps of the processing flowsheet for the project from ore beneficiation and leaching to purification and production of battery-grade lithium carbonate.
- Completion of the PFS outlines large scale, long life and low cost source of American made battery grade lithium chemicals (November 2024)

Green Technology Metals
Investor Insight
Green Technology Metals aims to build Ontario’s first integrated lithium business, developing two mining hubs and a downstream conversion facility to supply North America’s fast-growing EV and battery industry. The company’s approach is straightforward: bring Seymour into production, secure the downstream footprint at Thunder Bay with EcoPro, and then layer in Root as a long-life second feed. The plan is underpinned by offtake agreements, government funding and a management team with direct experience building lithium mines.
Overview
Green Technology Metals (ASX:GT1) is building Ontario, Canada’s first integrated lithium business, anchored by three upstream assets and a planned downstream conversion facility. The portfolio consists of the flagship Seymour project, the large-scale Root lithium project, and the Junior exploration project, which together provide a clear pipeline of feed into a proposed lithium hydroxide facility in Thunder Bay, Ontario.
The company is actively leveraging Canadian policy support for critical minerals development and supporting a growing number of EV and battery manufacturers in Ontario. The province’s Building More Mines Act, alongside several federal programs, is creating a supportive funding environment for new projects. GT1 has already received conditional approval for C$5.5 million from the Critical Minerals Innovation Fund (CMIF) to support road and infrastructure upgrades at Seymour. In addition, the company has received a letter of intent for a C$100-million project financing support from Export Development Canada, and has pending applications with SIF/NRCan and CMIF Round 2, including a C$5-million submission tied to the Root project. These mechanisms substantially de-risk the financing path and provide tangible momentum toward development.
The strategy is being executed in three phases. First, Seymour will be brought into production with a concentrator based on a dense media separation flowsheet, taking advantage of coarse spodumene mineralogy and proven metallurgical performance. Second, GT1 will construct the Thunder Bay lithium conversion facility in partnership with EcoPro Innovation, replicating proven hydrometallurgical technology to produce battery-grade lithium hydroxide. Finally, Root will be developed as the company’s second, larger mining hub, designed to provide long-life scale and additional feed into the Thunder Bay facility.
Pilot processing of 600 kg of Seymour concentrate produced exceptional overall recoveries averaging >94 percent.
Strategic partnerships reinforce this integrated model. LG Energy Solution has secured a binding offtake for a portion of Seymour’s concentrate production and has invested directly into GT1, providing early validation of the project’s place in the EV supply chain. EcoPro Innovation, as the company’s technical partner on the Thunder Bay facility, has already piloted Seymour concentrate into high-purity lithium hydroxide.
Company Highlights
- Integrated strategy in Ontario: The Seymour and Root projects form the foundation for a vertically integrated lithium business, supported by a proposed lithium hydroxide plant in Thunder Bay, Ontario, with rail, port, power, gas and water access.
- Marketing and offtake secured: LG Energy Solution has a binding offtake for 25 percent of Seymour concentrate and has invested directly into the company, demonstrating strong downstream demand.
- Strategic process partner: EcoPro Innovation is co-developing the conversion facility. Pilot work has already produced battery-grade lithium hydroxide with high recoveries.
- Government backing: GT1 has secured conditional approval for significant funding programs, including C$5.5 million for road upgrades, a C$100 million project financing support LOI from EDC, and additional CMIF and SIF applications.
- Resource base: A combined inventory of over 30 Mt @ ~1.2 percent lithium oxide across Seymour and Root, providing both near-term production and long-life scale.
- By-product upside: Seymour hosts a significant rubidium resource in mica streams that could be recovered alongside lithium, creating an additional revenue line.
Key Projects
Seymour Lithium Project
The Seymour lithium project, near Armstrong, Ontario, contains a total resource of 10.3 million tonnes (Mt) @ 1.03 percent lithium oxide, including 6.1 Mt indicated @ 1.25 percent lithium oxide. Mineralization is hosted in the North and South Aubry pegmatites, which remain open along strike and at depth. An optimized preliminary economic assessment (PEA) demonstrated strong project economics based on a DMS-only concentrator producing 130 ktpa. Key numbers include a C1 cash cost of US$680/t, an after-tax NPV of US$251 million, an IRR of 33 percent, and a three-and-a-half-year payback.
The project benefits from existing road and rail access, low strip ratios, and simple metallurgy with coarse spodumene that responds well to dense medium separation (DMS). Mining leases were granted in August 2025, the environmental assessment submission has been lodged, and the closure plan is nearing completion.
An offtake agreement with LG Energy Solution secures sales for 25 percent of initial concentrate production. Seymour also includes a maiden rubidium resource (8.3 Mt @ 0.27 percent rubidium oxide, with a 3.4 Mt high-grade core at 0.40 percent), which can be recovered from mica streams already separated in the flow sheet, creating potential for a by-product circuit.
Thunder Bay Lithium Conversion Facility
GT1 and EcoPro Innovation are developing a lithium hydroxide monohydrate facility in Thunder Bay. The selected site is fully serviced with rail access, 44 kV power, municipal water and gas, and port facilities. The plant will replicate EcoPro’s operating hydromet trains, with two parallel ~13 ktpa back-end lines designed to scale with Seymour and Root concentrate supply.
Pilot-scale processing of 600 kg of Seymour concentrate at EcoPro’s Pohang facility achieved battery-grade lithium hydroxide, meeting downstream specifications with >94 percent overall recovery. This demonstration significantly de-risks the conversion step and supports ongoing financing discussions with Invest Ontario, SIF and EDC. The project is being advanced through PFS-level engineering, with permitting and JV structuring underway.
Root Lithium Project
Located in Northwestern Ontario, Root is GT1’s scale project, hosting 14.6 Mt @ 1.21 percent lithium oxide (10.0 Mt Indicated @ 1.32 percent). The April 2025 optimized PEA outlined a combined open-pit and underground mining scenario producing ~213 ktpa. The project carries a C1 cost of ~US$677/t, an after-tax NPV of US$668 million, an IRR of 53.5 percent, and a three-year payback.
Root enjoys outstanding infrastructure advantages: road and rail access, proximity to port, and most critically, grid hydro power delivered by the Watay transmission line, reducing both operating costs and upfront capex for power infrastructure. Drilling has confirmed stacked pegmatite bodies that remain open along strike and down dip, leaving scope for significant resource expansion. A bulk sample has been completed, with further testwork and pilot runs at EcoPro planned. Permitting is in its early stages, with a PFS targeted for 2026 and potential construction by late 2027.
Junior Lithium Project
The Junior project is located near Seymour and contains three drill-ready targets. Its proximity to the planned Seymour concentrator makes it a strategic satellite project, with the potential to extend Seymour’s mine life and provide incremental feed. Drilling is expected to test these targets in upcoming campaigns, potentially increasing the overall feed available for the Seymour hub.

Investor Insight
International Lithium offers investors exposure to the growing critical metals sector through its advanced-stage Raleigh Lake lithium-rubidium project in Ontario, early-stage copper-cobalt exploration at Firesteel in Ontario, and strategic focus on Southern Africa, all supported by strong infrastructure and a seasoned leadership team.
With strategic divestments, a robust financial position, and a focused growth strategy, International Lithium is well-positioned to meet the rising demand for lithium and other critical metals
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.
Recent strategic divestments, including the sale of the Avalonia project stake, have strengthened ILC's financial position, enabling focused investment in its core projects.
In 2025, International Lithium acquired an option from Lepidico (Canada) Inc. to purchase 100 percent of Lepidico (Mauritius) for C$975,000. Lepidico Mauritius holds an 80 percent stake in Lepidico Chemicals Namibia (Pty) Ltd., which owns the Karibib Lithium, Rubidium and Cesium Project in Namibia.
The project comprises two areas with fully permitted mining licences, known as Rubicon and Helikon. It also hosts one of the largest disclosed rubidium resources in Africa, along with significant lithium and cesium mineralization.
Exercising the Karibib option would position International Lithium to capitalize on an upswing in the lithium market while also cementing its role as one of the leading global players in rubidium. The project would expand its portfolio of some of the most significant cesium resources held by any non-Chinese company, strengthening its standing in three critical minerals that are increasingly vital to global supply chains.
The company is led by an experienced management team with a strong technical background in mineral exploration, project development and corporate finance. Supported by access to established infrastructure, a commitment to sustainable development practices, and a clear strategic focus, International Lithium is well-positioned to capitalize on the increasing global demand for lithium and other essential materials critical to the clean energy transition.

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

New mineralised pegmatites identified at Lithium Ridge as exploration drilling commences with SQM
HIGHLIGHTS
- 14 000 metres of Orientated Diamond Drilling ("DD") underway across priority lithium targets.
- High resolution geological mapping and sampling already identifying new pegmatites with visible spodumene mineralisation.
- Programme builds on historical results of up to 2.13% Li₂O along a 6 km mineralised ridgeline.
Anthony Viljoen, Chief Executive Officer, commented:
"The commencement of drilling at Lithium Ridge with our tier-1 joint-venture partner, SQM, is a significant step forward in unlocking one of Namibia's most exciting lithium opportunities. The encouraging historical results of up to 2.13% Li₂O along the 6km ridge line, are already being complemented by a new geological mapping and sampling programme that has identified additional mineralised pegmatites containing visible spodumene crystals. This strengthens our confidence in the scale and quality of the project. The investment by SQM underscores Lithium Ridge's potential and Namibia's growing role in the global supply of critical minerals. We expect this programme to provide the foundation for fast-tracking the project towards development."
Lithium ridge exploration programme
The Lithium Ridge mining licence is located only 35 kilometres from Andrada's producing Uis tin mine and hosts multiple high-priority lithium-bearing pegmatites, with associated tin and tantalum credits.
The current programme is designed to:
- Unlock the full potential of the mineralised ridge and,
- Extend exploration across the wider licence area where new spodumene - bearing pegmatites have been identified.
The 14 000 metre DD programme will comprise approximately 120 orientated holes, to determine the depth extensions and continuity of the extensive mineralisation already identified at surface. Historical work confirmed grades of up to 2.13% Li₂O and metallurgical spodumene recoveries of up to 80%, producing a premium 6.8% Li₂O concentrate with low iron levels. These results were on drill chip samples produced during reverse circulation drilling at Lithium Ridge. (See announcement dated 5 December 2023). This programme is expected to significantly enhance the geological understanding of Lithium Ridge and demonstrate its economic potential as a large-scale, high quality lithium project.
