The Swanson Tantalum Project, located near Warmbad in Namibia’s Karas Region, is one of the country’s most promising critical-minerals developments — and potentially the first modern tantalum-producing mine in independent Namibia.
Compact and low-capex, Swanson could position the country among the world’s few stable and traceable suppliers of this rare technology metal, used in capacitors, medical implants, aerospace alloys, and electric vehicles.
The project is 100% owned by Orange River Pegmatite (Pty) Ltd, a Namibian subsidiary of Arcadia Minerals Limited (ASX: AM7).
Since its discovery in 2021, Swanson has attracted sustained investor interest thanks to its simple geology, clean mineralogy, and strong environmental, social, and governance (ESG) credentials.
Arcadia has completed a competitive offtake and funding process that attracted several international and regional groups, with several now shortlisted to finance the mine’s development.
The project’s low capital cost — about US$9.8 million (≈ N$180 million) — and its status as a conflict-free tantalum source make it particularly attractive to technology manufacturers seeking secure supply chains outside Central Africa.
Discovery and geology
Swanson sits within the Tantalite Valley pegmatite belt, a mineral-rich corridor straddling Namibia’s southern border with South Africa.
The area has long been known for its lithium–caesium–tantalum (LCT) pegmatites, and Arcadia’s fieldwork redefined its potential through systematic exploration, including mapping, trenching, sampling, and over 8,000 metres of reverse-circulation and diamond drilling.
This effort culminated in a maiden JORC 2021 Mineral Resource Estimate of 2.59 million tonnes at 486 ppm Ta₂O₅, containing approximately 1,257 tonnes of tantalum pentoxide, along with credits for niobium and lithium.
The mineralisation occurs in gently dipping pegmatite bodies within granitic host rocks, which are amenable to low-strip, open-pit mining.
Metallurgical testwork has demonstrated 80–85% recovery rates through gravity and magnetic separation — a low-energy processing route that reduces reagent use and environmental impact.
Licensing and development
In June 2022, the Namibian Ministry of Mines and Energy granted a mining licence (ML 243) to Arcadia’s Namibian arm, Orange River Pegmatite (Pty) Ltd, marking a significant step toward commercialisation.
Detailed engineering and site layout planning have since been completed, with the project now at the funding and early works stage.
Arcadia’s technical studies outline a small but scalable mine plan designed to produce high-grade tantalum concentrate.
The operation would rely on modular gravity-separation technology, with minimal water and power requirements — an advantage in Namibia’s arid southern terrain.
Early construction is expected to create dozens of direct jobs in Warmbad and nearby communities, with additional employment through logistics, maintenance, and local supply contracts once mining begins.
The company envisions Swanson as an anchor asset capable of generating early cash flow to fund its broader Namibian portfolio, including the TVC Ta-Li Project, where exploration has identified additional tantalum- and lithium-bearing pegmatites.
Ownership and investment
Swanson is wholly owned by Orange River Pegmatite (Pty) Ltd, a Namibian-incorporated company, to ensure local operational control and compliance with national mining laws.
Parent company Arcadia Minerals Limited, based in Perth, Australia, is listed on the Australian Securities Exchange (ASX: AM7) and maintains a diversified portfolio across Namibia, including lithium, nickel, copper, and gold prospects.
Arcadia’s first financing attempt — a proposed offtake and funding deal with China’s HeBei Xinjian Construction CC — fell through when the partner defaulted on payment obligations.
Rather than halting progress, the failure led Arcadia to reopen negotiations with a broader and more competitive pool of financiers.
The new process has drawn institutional investors, strategic metals traders, and end-user manufacturers seeking long-term partnerships.
Jobs, community, and environmental footprint
Swanson’s footprint is intentionally compact. Arcadia’s design philosophy centres on low energy consumption, minimal water use, and reduced waste generation.
The company has pledged to source local labour and contractors wherever possible, with an initial operational workforce projected at 50–80 people, expanding to around 150 at peak activity.
Beyond direct employment, Swanson’s logistics and service requirements — including fuel supply, haulage, catering, and accommodation — are expected to stimulate secondary economic activity in the Warmbad district.
The project’s environmental management plan incorporates rehabilitation commitments and community consultation, ensuring compliance with Namibia’s Environmental Management Act.
Present and future outlook
As of late 2025, Arcadia is finalising financing agreements and preparing for construction readiness at Swanson.
The company’s Final Investment Decision (FID) timeline remains flexible but is expected to follow the completion of funding and permitting milestones.
Once operational, the mine could produce several hundred tonnes of tantalum pentoxide concentrate annually — a meaningful contribution to global supply, which artisanal and high-cost producers in Central Africa currently dominate.
Swanson’s success would mark Namibia’s entry into the global tantalum market, strengthening the country’s profile as a diversified critical-minerals hub alongside its uranium, lithium, and rare-earth operations.
In essence, Swanson is more than a mine: it’s a test case for how Namibia can harness small, efficient, and ethical projects to build a modern critical-minerals industry.
With its mining licence secured, funding in motion, and local groundwork underway, the Warmbad project signals the beginning of a new chapter — one in which Namibia’s southern desert becomes a quiet but powerful contributor to the world’s clean-energy and digital future.
