Arcadia Minerals Ltd (ASX:AM7, FRA:8OH) (Arcadia or Company), the diversified exploration company targeting a suite of projects aimed at Tantalum, Lithium, Nickel, Copper and Gold in Namibia, is pleased to announce that a regional investigation into its Bitterwasser Lithium Project (Bitterwasser Project) indicated the potential presence of a large-scale lithium-in-clay and lithium-in-brines minerals-system, arising from underlying lithium bearing basement rocks activated through geothermal activity and fed into sedimentary-clay environments and sub-terranean brine aquifers via deep-seated fault structures (Bitterwasser System).
HIGHLIGHTS
A comprehensive review of available geological literature and recent exploration work at the Bitterwasser Lithium Project confirmed that:
- Extensive tectonic rift-related fault structures have defined a closed basin (the Kalkrand half-graben), similar to Clayton Valley in Nevada
- Basement rocks are amenable to be Lithium-rich source rocks for:
- sub-terranean, possibly lithium enriched, brine aquifers, and
- the already proven lithium enriched sedimentary clay pans
- Lithium-in-clay mineralisation is spatially linked to extensive rift-related fault structures and likely caused by fluctuating lithium enriched water table
- Historical water borehole sampling across the properties contains saline water (refer Figure 3 below), with high Boron and Potassium content (elements which are associated with lithium brine deposits)
- Evidence of geothermal activity exists within the Bitterwasser Basin, possibly serving as the method in which the lithium mineralisation was extracted and transported from the source rocks
- Geological model (Refer Figures 1 & 5) has been formulated to refine and advance Arcadia’s work program to include:
- Stratigraphic drilling to construct a geological section of the basin and understand basin parameters,
- Water sampling of hot springs and groundwater to determine mineralogical content and potential for geothermal energy harvesting,
- Airborne geophysical surveys to define basin aquifer targets, and
- Targeted drilling of potential trap sites of lithium in brine aquifers and additional lithium clay layers
The comprehensive review of academic literature1 and recent exploration undertakings (including drilling) have refined Arcadia’s understanding of the Bitterwasser Basin, including the likely source rocks of Lithium mineralisation and the role known geothermal activity in the area plays in deposition of mineralisation.
Bitterwasser Basin
A review of academic literature confirmed that extensive rift-related fault structures under the Project area have defined the Kalkrand regional basin-forming half-graben2 (Bitterwasser Basin). The entire Bitterwasser Basin is enclosed by tenements owned by Arcadia’s associated companies, Bitterwasser Lithium Exploration (Pty) Ltd and Brines Mining Exploration Namibia (Pty) Ltd.

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.

Figure 1 – Pursuit’s 99.5% Li₂CO₃ Sample Ready for Dispatch to Potential Offtake Partners
In relation to the dispatch of samples, Pursuit Managing Director & CEO, Aaron Revelle, said:
“Achieving 99.5% lithium carbonate purity is a major technical milestone for Pursuit and a clear demonstration of the capability embedded within our flowsheet, team, and pilot plant infrastructure. It not only validates the compatibility of our process design with Rio Grande Sur brines but also confirms our ability to deliver a consistently high-quality product suited to a wide range of industrial and energy storage applications. Dispatching these samples to potential offtake partners is a critical first step in our commercialisation pathway, enabling product qualification and accelerating engagement with strategic customers in tough market conditions. As we transition into the next phase of development, our focus is firmly on advancing feasibility for our 5,000tpa operation and securing long-term partnerships that will underpin the future production and growth of the Rio Grande Sur Project.”
Initial pilot production at Pursuit’s 250tpa Pilot Plant in Salta successfully produced 15 kilograms of lithium carbonate at 98.9% purity, validating both the compatibility of the Rio Grande Sur brine and the efficiency of the Company’s conventional processing flowsheet. To enhance product quality and simulate potential refinement steps at commercial scale, a portion of this material was further treated at bench scale using fractional crystallisation (FX) and ion exchange (IX) techniques. These post processing steps upgraded the product to 99.5% purity, meeting established benchmarks for technical-grade lithium carbonate.
The final product assays confirm not only the effectiveness of Pursuit’s downstream purification strategy but also the scalability and robustness of its broader flowsheet. This achievement represents a critical milestone on the path to commercial readiness supporting key feasibility assumptions, validating end product quality, and enabling active engagement with prospective offtake partners.
Pursuit is well positioned to undertake additional small-batch production as required to meet partner qualification needs and advance strategic discussions. Furthermore, it demonstrates Pursuit’s capability to produce high-purity lithium carbonate suitable for industrial use, with potential to meet battery-grade specifications through additional refinement.

Investor Insight
Leveraging early-stage land acquisition, accelerated drilling and a strong strategic partnership, Lithium Africa delivers maximum exploration efficiency, capital leverage and de-risked lithium discovery upside at scale.
Overview
Lithium Africa is an exploration company purpose-built to capitalize on the next cycle of lithium demand. Its strategic mission is to discover, de-risk and monetize Tier 1 lithium assets through data-driven targeting, aggressive fieldwork and value-driven exits. The company's unique 50/50 joint venture with Ganfeng Lithium is the cornerstone of its strategy, providing both financial leverage and industrial alignment at the earliest stages of project development.
Africa remains largely underexplored for lithium despite sharing geological similarities with major hardrock lithium belts in Canada and Australia. Lithium Africa is the first company to systematically deploy a multi-jurisdictional discovery strategy across the continent – combining top-tier geology with capital efficiency and strategic clarity.
At the heart of Lithium Africa’s model is its joint venture with Ganfeng Lithium, one of the top two lithium chemical producers globally. The 50/50 JV, established in 2023, enables Lithium Africa to double its capital efficiency, with $1 raised equating to $2 spent on exploration. The partnership provides unmatched advantages: access to Ganfeng’s downstream processing know-how, established customer relationships with Tier 1 OEMs, and a long-term offtake framework that allows Lithium Africa to retain flexibility and optionality on any asset monetization.
Lithium Africa does not intend to develop or operate mines. Instead, the business model is designed around efficient land acquisition, aggressive de-risking via trenching, sampling, and early drilling, and ultimately monetizing high-value discoveries through royalties, sales or carried interests. In a down market, the company is actively pursuing counter-cyclical M&A opportunities to acquire stranded or undercapitalized lithium assets. With this strategy, Lithium Africa provides shareholders exposure to world-class discovery upside with significantly reduced financing risk.

Key Projects
Zimbabwe
Birthday Gift Project (Flagship)
The Birthday Gift project is Lithium Africa’s flagship asset and highest-priority exploration target. Located along a >12 km pegmatite corridor, the project hosts three parallel, flat-lying spodumene-bearing pegmatites within metasediments. Surface trenching has returned multiple significant intercepts, including 100 m, 67 m, and 55 m widths with true thicknesses averaging ~35 m. Rock chip samples from fresh spodumene zones have returned assays as high as 5.25 percent lithium oxide. More than 3,000 geochemical samples have been collected, and a 1,500-meter RC drill program commenced in January 2025 to test a 1,300-meter strike length.
The pegmatites remain open at depth and along strike. SGS South Africa is performing ICP assay analysis, and environmental permitting and trenching on the western trend are ongoing.
The Birthday Gift asset has strong potential to support an inaugural resource estimate by late 2025.
West Africa
Torakoura in Bougouni District, Mali
Lithium Africa controls six highly prospective licenses in Mali, located within the prolific Bougouni Basin, home to Leo Lithium’s Goulamina project, one of the world’s largest spodumene deposits. The Torakoura permit is situated along the same structural corridors and granitic host rocks. Surface exploration has identified spodumene-bearing pegmatites, supported by strong lithium and pathfinder anomalies from historic soil sampling.
Initial drilling at Torakoura began in 2024 but paused for LIBS-to-ICP calibration. A new RC drilling campaign resumed in Q4 2024. These permits offer substantial scale and proximity advantages in a well-established lithium district with proven permitting and development pathways.
Adzopé & Regional Licenses, Côte d’Ivoire
In Côte d’Ivoire, Lithium Africa holds four early-stage but highly promising permits totaling 1,254 sq km. The Adzopé license has returned rock samples with lithium oxide values up to 0.98 percent. Field mapping and lithological sampling have been completed, and a 21,700-meter auger drilling program is planned to refine targets for follow-up RC and core drilling. The region is emerging as a new pegmatite belt in West Africa, and Lithium Africa has first-mover status in building a pipeline of discovery-stage projects.
Kobikoro Project, Guinea
The Kobikoro project in southeastern Guinea consists of four licenses covering 376 sq km in the Archean Kinema-Man domain. This district is part of the underexplored Kissidougou pegmatite belt. Historical stream sediment geochemistry conducted by BRGM highlights multiple anomalous trends in lithium, tantalum and niobium. The standout feature is a 20 km-long lithium-tantalum-niobium anomalous zone aligned with regional structures and underlain by fractionated granite intrusions.
Morocco
Bir El Mami
In 2024, Lithium Africa acquired a 585 sq km, district-scale land package in the Bir El Mami region of Morocco, located on the northern extension of the Tasiast greenstone belt. The project is notable for its spodumene-bearing pegmatites confirmed by surface rock samples, which include lithium values up to 862 parts per million (ppm), and historic soil anomalies up to 363 ppm. The region is emerging as a key lithium district given Morocco’s favorable trade agreements and a growing domestic EV battery manufacturing base. Lithium Africa is currently Morocco’s only major lithium concession holder, and early-stage target identification is underway as of Q1 2025. The company is well positioned to be Morocco’s lithium sector leader and consolidator.
