Namibia Critical Metals’ C$11 Million DFS Push Makes Lofdal a Processing Test

Namibia Critical Metals has moved Lofdal into the stage where metallurgy, product specification and local processing matter more than adding another headline resource estimate.

The company said the joint management committee overseeing the Namibian heavy-rare-earth project approved as much as C$11 million of additional funding for the next phase of the definitive feasibility study. SGS Canada has received the first major metallurgical and geometallurgical contracts, with work intended to validate the full route from run-of-mine ore to separate light- and heavy-rare-earth carbonate products.

That is a material change in the investment case. Lofdal is already unusual because its value is concentrated in dysprosium, terbium and yttrium rather than the larger-volume light rare earths that dominate most development stories. Those elements are used to preserve permanent-magnet performance at high temperatures, making them particularly important in electric-vehicle drivetrains, wind turbines and defence applications.

The December 2025 pre-feasibility study outlined average production of about 2,000 tonnes a year of total rare-earth oxides over a 13-year mine life. The product mix included roughly 119 tonnes of dysprosium, 18 tonnes of terbium and 841 tonnes of yttrium annually. It estimated initial capital of US$348 million, including contingency, with an after-tax net present value of US$275 million and a 19% internal rate of return under the base case.

Those numbers show why recovery is now the central variable. The company’s own sensitivity work indicates that changes in metallurgical recovery can move after-tax project value by hundreds of millions of dollars. A deposit rich in high-value heavy rare earths can still disappoint if flotation, leaching, impurity removal and product precipitation lose too much metal or produce a carbonate that customers cannot qualify.

The expanded DFS is designed to answer that problem with more than a desktop engineering update. The programme includes variability testing across ore domains, geometallurgical modelling and process work intended to generate the operating data needed for plant design and project finance. SGS Lakefield’s role matters because lenders and strategic partners will expect a flowsheet supported by repeatable bench and pilot-scale results, not only laboratory recoveries from selected samples.

The second issue is where value is captured. Namibia Critical Metals said the programme will assess further downstream processing in Namibia rather than treating the country solely as a source of concentrate. Producing separate light- and heavy-rare-earth carbonate products locally would require tighter control of reagent consumption, water, residues and impurities, but it could also retain more technical capability and export value in Namibia.

Japan’s involvement gives the project a strategic route to market. JOGMEC has worked with Namibia Critical Metals at Lofdal since 2020, while Toyota Tsusho joined the development platform in March 2026 after assuming part of JOGMEC’s option interest. Toyota Tsusho said it would contribute its experience in rare-earth refining, magnets and supply chains, with a view to future supply to Japan.

That partnership reduces one of the normal risks facing junior rare-earth developers: trying to finance a complex separation project without an industrial customer or government-backed partner. It does not eliminate the challenge. The DFS still has to convert a US$348 million concept into a buildable design, establish product quality, control reagent and residue costs and show that the mine can compete through rare-earth price cycles.

The resource base provides room to optimise. JOGMEC has cited 55.8 million tonnes of measured and indicated resources grading 0.16% total rare-earth oxides at Area 4, with additional inferred resources and a second resource at Area 2B. The grades are modest, so economics depend on the unusually heavy rare-earth-rich basket and on achieving the planned recoveries consistently.

The next catalyst is therefore not another broad claim about supply security. It is evidence from SGS that representative Lofdal ore can be processed into repeatable, saleable heavy-rare-earth products at costs that support the PFS economics. If that work succeeds, Toyota Tsusho and JOGMEC give the project a credible bridge from a Namibian deposit to Japanese magnet customers. If it does not, the strategic importance of dysprosium and terbium will not compensate for an inefficient flowsheet.

Lofdal has passed the stage where geology alone can carry the story. The C$11 million programme is a test of whether a strategically attractive resource can become an industrial process that banks, customers and Namibia itself are willing to support.
