Arcadia Minerals has moved to recalibrate its Namibian portfolio by ending a stalled funding deal at the Swanson Tantalum Project and opening a competitive process to bring in a new development partner.
The company is also lining up drilling at Karibib and reporting basin-scale critical minerals signals across the Tantalite Valley Complex.
The Guernsey-domiciled, Namibia-focused explorer says the past year was about “unlocking optionality” across lithium, tantalum, nickel, copper, gold and PGEs, even as sentiment cooled in parts of the lithium market and cash remained tight.
The most immediate pivot came at Swanson. After development slowed during the September 2024 quarter due to non-payment by HeBei Xinjian Construction CC, Arcadia formally terminated the subscription agreement on 30 January 2025.
The decision left Arcadia with its 80% interest intact via Orange River Pegmatite (Pty) Ltd and freed the company to court new backers.
An information memorandum has since been issued, and discussions with several interested parties are underway. The company framed the reset as a path to restart procurement of gravity and spiral circuits and to push the tantalum-led, lithium-bearing pegmatites back toward production planning once a credible financier-operator is secured.
Capital to keep those conversations moving arrived on 30 April 2025, when Arcadia secured US$150,000 in interim funding through a convertible unsecured non-recourse loan.
Management stated that the funds are earmarked to advance partner talks for Swanson and potential farm-outs or joint ventures at Karibib and the TVC projects, aligning with a strategy of advancing assets through joint ventures or strategic equity rather than balance-sheet build-outs.
The company also presented its portfolio to investors at Mining Indaba on 3 February 2025, signalling that Namibia remains the centre of gravity for deal-making.
On the exploration front, Karibib is next in the queue. On 12 March 2025, Arcadia outlined targets for a 1,000-metre RC programme at Gamikaubmund, east of the confluence of the Gamikaub and Swakop rivers on Farm Ukuib 84.
The skarn-type calc-silicate outcrops host historical workings and sampling, including work by Gold Fields in the 1980s. Arcadia’s drilling is designed to test mineralisation to depth and follow up on induced-polarisation anomalies that could extend strike.
With mineralisation controls now better constrained, the planned 15-hole campaign aims to convert surface showings and copper-stained skarns into subsurface continuity that could reposition Karibib within the company’s copper-gold pipeline.
Parallel to the technical work, Arcadia has initiated discussions with partners to accelerate any discovery toward development.
Further south, work across the Tantalite Valley Complex delivered one of the report’s more intriguing datapoints. Following a 97-site stream-sediment orientation survey reported on 31 October 2024, Arcadia released results on 30 May 2025 showing anomalous signatures for gold, cobalt, chromium, copper, nickel, palladium and platinum associated with the full extent of the complex.
Ultra-fine fraction sampling also returned elevated lithium outside the core intrusion, including in drainage systems tied to the broader Swanson area, hinting at additional mineralised pegmatites beyond the known field.
Historical boreholes drilled between 1972 and 1976 by Rio Tinto Exploration, Tantalite Valley Minerals, and Southern Sphere intersected nickel and copper over mineable widths, and Arcadia’s re-sampling of legacy cores recorded the first noted PGE and gold mineralisation in the area’s ultramafics.
With 60 LAG orientation samples in the lab at year-end, the TVC now reads as a district-scale critical-minerals target where both base and precious metals—and possibly lithium in adjacent systems—could co-exist.
At Bitterwasser, the narrative is split between clays and brines. On 24 July 2024, Arcadia reported high-grade lithium leachates from clay material after sulphate roasting at 850°C and water leaching at 80°C without acids, producing low-impurity solutions that the company views as a potentially more straightforward processing route.
By contrast, the brine programme came under review after assays from two accredited laboratories diverged materially across major ions and lithium—by as much as 210% for Li—raising questions about ICP interference and prompting a pause to re-tool sampling and analytical methods before publishing verifiable results.
With lithium markets softening over the year, management said it had shifted focus from Bitterwasser toward projects offering nearer-term optionality, while keeping Bitterwasser’s clay resources in good standing. As at 30 June 2025, the Eden and Madube pans together hold an inferred 98.9 Mt at an average 622 ppm Li for 327,285 t LCE, with no change to the resource during the period.
Resource and reserve positions otherwise remained steady. Swanson’s mineral resource and ore reserve figures were unchanged from prior disclosures, and Arcadia reported no material resource updates during the year.
Governance statements reiterated JORC 2012 compliance, competent person sign-offs and ongoing internal and external QA/QC reviews.
Financially, Arcadia’s profile was consistent with an exploration-stage company.
For the year ended 30 June 2025, the group recorded a net loss after tax of US$888,020, compared to a US$1,654,176 loss in the prior year, with net assets of US$11.50 million.
Cash at year-end was modest at US$1,990, underscoring management’s emphasis on partner funding, farm-outs and selective interim facilities to bridge technical milestones.
The company closed the period with 117,383,433 CDIs on issue and confirmed Raubex Group Limited as a holder of more than five per cent of the register as of 30 June 2025.
Taken together, the latest report sketches a pragmatic reset: stabilise Swanson by replacing a non-performing funder; prosecute a tightly scoped drill program at Karibib to elevate copper-gold targets; convert TVC’s geochemical and historical signals into modern vectors for nickel, copper, PGEs—and perhaps lithium in adjacent drainages; and preserve Bitterwasser’s clay value while fixing the brine workflow.
It is a portfolio approach built for a market where capital rewards clarity, credible partners and near-term proof points. If Arcadia lands a capable sponsor at Swanson and delivers drill-bit validation at Gamikaubmund while sharpening the TVC target map, Namibia could yet turn this diversified explorer’s optionality into traction.
