Arcadia Minerals Limited (ASX:AM7, FRA:8OH), the diversified exploration company targeting a suite of projects aimed at Tantalum, Lithium, Nickel, Copper and Gold in Namibia, is pleased to announce that Snowden Optiro has provided the Company with an Independent Geological Report titled “Report for Orange River Pegmatite Geology and Resource Estimation of the D, E and F Pegmatites, Project Number JB018308, May 2022” 1 which consist of a revision of a Mineral Resource Estimate, announced by the Company on 23 September 20212 , for the Company’s 80% owned Swanson Tantalum exploration project situated in Tantalite Valley, Namibia.
HIGHLIGHTS
- Revision of September 2021 Mineral Resource delivers a new estimate including a total indicated and inferred resource of 2.59Mt (an increase of 115%) at an average grade of 486 ppm Ta2O5 (an increase of 17.9%), 73 ppm Nb2O5 and 0.15 % Li2O.
- Total in situ metal content of 1,257 tonnes (represents an increase of 154%)
- Mineral Resource Categorisation:
- Indicated Resource: 1,439Mt at an average grade of 498 ppm Ta2O5, 72 ppm Nb2O5 and 0.14 % Li2O,
- Inferred Resource: 1,145Mt at an average grade of 472 ppm Ta2O5, 75 ppm Nb2O5 and 0.17 % Li2O
- To date only 15 of the more than 200 known pegmatites present over Arcadia’s three licenses have been explored.
- Mineral Resource Estimate conducted over 10 (of 15) outcropping opencastable shallow pegmatites located at Swanson, namely the D0, D1, D2, E2, E3, E4, E6, E7, E8 and F1.
- Public domain information from 11 Tantalum operations from around the world were used to benchmark the Swanson project against other Tantalum projects. The weighted average grade of these 11 deposits is 233 ppm Ta2O5, indicating that the Swanson Project grades are significantly above its global peer group and of the highest grades in the world.
- The Mineral Resource Estimate is to form the basis of a feasibility study currently underway (expected to be completed in September 2022).
- Mineral Resource is based on an exploration program that includes:
- 283 channel / chip samples and
- 52 diamond boreholes on a 50m grid spacing
Philip le Roux, the CEO of Arcadia stated:
“When the company commenced the phase 2 drilling program at Swanson the primary objective was to increase the previous JORC resource of 1,214Mt @ 412 ppm Ta2O5 we set out to increase the resource to more than 2.5 million tonnes. It is very pleasing to announce that we’ve achieved this goal and more, by attaining an 18% higher grade than what was reported under the maiden Mineral Resource published in September 2021. The results bode well for the Company’s upcoming feasibility study, which is already underway with an outcome expected by September 2022.”
Jurie Wessels, the Executive Chairman of Arcadia stated:
“With this impressive result our priority for the Swanson project has progressed towards the feasibility study, with the aim to demonstrate that the production of a 25% Ta2O5 concentrate is feasible and to prove that Swanson will become the cash generator we envisioned it to be for Arcadia. Additionally, we’ll aim to explore the abundant pegmatite swarms scattered throughout our licenses in Tantalite Valley to possibly replicate the resources we discovered at Swanson and thereby increase more value for our shareholders.”
Revised Mineral Resource Estimate
Through its 80% owned subsidiary Orange River Pegmatite (Pty) Ltd (“ORP”) Arcadia ownsthe exploration rights to three EPL’s (5047, 6940 and 7295). The total amount of pegmatites mapped by the South African Council of Geoscience over the three ORP EPL’s amount to more than 200 pegmatites (see Figure 1). All indications are that the same mineralisation model present in the 15 pegmatites explored to date at Swanson could be applicable to these pegmatites.
Fifteen individual pegmatite bodies > 1 m thickness within the Swanson Pegmatite Swarm
were identified as high priority and were then targeted for mapping, sampling and drilling.
This area was delineated, and a high-resolution drone survey was undertaken to assist with
the planning of the exploration program. The pegmatite units were clustered and named “A”
to “F” in a west to east direction as shown in Figure 2.

SUMMARY OF MINING EXPLORATION FOR THE QUARTER
Bitterwasser Lithium Project
Assay results for the outstanding 32 drill holes from the 64-hole follow-up auger drilling campaign completed on 9 February 20224 over the Eden Pan was received during the quarter. All the drill holes commenced in the mineralised Upper Brown Clay Unit and every hole, except two drill holes where thin clay units were intercepted at the edges of the Eden Pan, were sampled from top to bottom up to a depth of 9.60m. Notably, the entire sequence of the drill holes sampled (i.e. Upper Brown Clay Unit and Middle Green Glay Unit) returned lithium mineralisation5.
The Middle Green Clay Unit, lithologically named the Middle-Unit (MU), comprises the dominant lithological unit from which the maiden Mineral Resource6 was derived. This green clay unit was intersected in 18 of the 32 drill holes from which assay results were received and extended from a depth of 1.4 m below surface to the maximum End-of-Hole (EOH) depth of 9.60m. A total of 43 holes from the 64-hole follow-up auger drilling campaign intersected the Middle Green Clay Unit at similar depths.

Kum-Kum Nickel Project Mineral Systems Approach Results
HIGHLIGHTS
- The Department of Earth Sciences at the University of Stellenbosch concluded a Minerals Systems Approach investigation over the Kum-Kum Ni-Cu-PGE Project Licenses
- During the investigation several historical documents containing exploration results over the Kum-Kum Project were discovered, which reported best historical borehole intersections from three boreholes drilled by Rio Tinto Exploration, Tantalite Valley Minerals and Southern Sphere between 1972 and 1976 as follows:
- 16.00 m @ 0.65% Ni, 0.16% Cu
- 6.00 m @ 0.61% Ni, 0.30% Cu
- 2.44 m @ 0.62% Ni, 0.30% Cu
- Historical core samples obtained were sampled and returned the first known record of PGE and Au mineralisation in the ultramafic units of the Tantalite Valley Complex. The best results indicated mineralisation of:
- 0.71% Ni, 0.28% Cu, 0.84 g/t Pd and 0.4 g/t Pt in orthopyroxenite
- 0.58% Ni, 0.30% Cu, 0.69 g/t Pd, 0.31 g/t Pt and 0.26% Au in orthopyroxenite
- The primary magmatic sulphides comprise of coarse-grained pentlandite, pyrrhotite, and chalcopyrite
- Whole rock geochemistry highlights the geochemical similarities between the TVC and the Kum-Kum complexes. The TVC crystallized as a mafic/ultramafic layered intrusion and likely from a primitive mantle-derived parental magma.
Philip le Roux, the CEO of Arcadia stated:
“Historical drilling results reporting high values of Nickel and Copper mineralisation attracted us to the Kum-Kum Project. From the work done by the team from the University of Stellenbosch it is evident that PGE and Au mineralisation is also present and that we are looking at a geological environment that possibly could contain a stratiform Ni-Cu-PGE disseminated sulphide ‘reef’ horizon. The prospect of possibly discovering a polymetallic (Ni, Cu, Au & PGE’s) deposit has increased the allure of the KumKum Project for us, which we will eagerly follow up with further exploration. The results of the study will assist the Company to focus its exploration efforts in order to define drill targets.”
Mineral Systems Approach Results
The Tantalite Valley Complex (TVC) has been subject to a geological study by a team from Arcadia and the University of Stellenbosch involving two field sampling campaigns (8 days; 94 field samples collected) augmented with detailed consideration of historical drill core segments (57 samples), and supporting data from historical records, hyperspectral mapping, and stream sediment sampling.
Collected field- and core- samples were subjected to a suite of analytical protocols including reflected- and transmitted-light optical petrography, whole-rock major and trace element chemistry, precious metal assays, sulphur isotope analyses, scanning electron microscopy with associated spectrometries and in-situ Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) of individual sulphide grains. Together, these results provide novel insights into the known mineralisation and prospectively of the TVC.
The TVC is a ~7 km long by 3.3 km wide and roughly oval-shaped mafic-ultramafic complex representing a fault-bound block inside a dextral Pofadder Shear Zone (PSZ) that cuts across southern Namibia. Existing geochronology places the TVC as a ~1.2 Ga intrusion and roughly coeval with a Kum Kum Klippe mafic complex that is located roughly 40 km south-east and along the strike of the PSZ.
Whole rock geochemistry highlights the geochemical similarities between the TVC and the Kum Kum suite, but with the former uniquely showing much stronger geochemical evidence for overwhelmingly cumulate rocks. This implies that the TVC crystallized as a significant mafic/ultramafic layered intrusion and likely from a primitive mantle-derived parental magma that originated from a metasomatized mantle.

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.
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.
Company Highlights
- International Lithium is focused on developing lithium and critical metals projects in Canada and Southern Africa, aiming to deliver shareholder value through project development, strategic partnerships and project sales.
- Raleigh Lake is ILC’s wholly owned flagship lithium-rubidium project in Ontario, Canada, with a positive PEA completed in December 2023.
- ILC holds a 90 percent interest in the Firesteel copper and cobalt project in Northwestern Ontario, with exploration permits filed and drilling programs planned.
- The company has applied for exclusive prospecting orders (EPOs) in Zimbabwe and is continuing to review further exploration opportunities in Southern Africa.
- ILC is debt-free with a robust financial position. It has monetized its non-core assets, including the sale of its stake in the Avalonia project in Ireland, resulting in a C$2.5 million payment and a 2 percent net smelter royalty.
- The company is led by an experienced management team with a proven track record in advancing mineral exploration projects.
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
