Energy Fuels Rare Earth Processing Could Receive $725mn US Defense Loan

Energy Fuels

Energy Fuels rare earth processing plans could receive up to $725mn in conditional financing from the US Department of Defense, supporting a major expansion of domestic separation, refining and rare earth metal production.

Energy Fuels rare earth processing strategy centres on its White Mesa mill in Utah, where the company plans to process monazite concentrates into light and heavy rare earth products alongside uranium and vanadium.

Energy Fuels rare earth processing expansion is strategically important because it targets several stages where the US remains heavily dependent on overseas capacity. The company ultimately plans to connect oxide production with domestic rare earth metal and alloy manufacturing.

The proposed loan remains subject to due diligence, final agreements and closing conditions, but it could substantially accelerate Energy Fuels' transition from mineral developer into an integrated critical materials producer.

White Mesa Expansion Targets NdPr and Heavy Rare Earths

The first phase at White Mesa is designed to process up to 10,000 t/yr of monazite concentrate and produce around 1,000 t/yr of neodymium-praseodymium oxide.

The operation will also generate concentrate containing samarium and other heavy rare earth elements.

Energy Fuels is installing additional equipment to process mixed rare earth carbonates and produce separated light and heavy rare earth oxides. Commercial production from this expansion is scheduled for mid-2027.

Phase 2 would significantly increase output. Planned additional capacity includes 5,513 t/yr of NdPr, 48 t/yr of terbium and 165 t/yr of dysprosium.

The expansion would also produce 748 t/yr of concentrate containing samarium and other heavy rare earths.

These materials are strategically important for high-performance permanent magnets used in defence, aerospace, electric vehicles, robotics and other advanced technologies.

The Phase 2 project carries an estimated capital cost of $419mn. Energy Fuels estimates NdPr operating costs of $29.39/kg using feedstock from its Vara Mada project in Madagascar.

Global Feedstock and US Alloy Capacity Build an Integrated Chain

Energy Fuels is developing several heavy mineral sands projects that could provide monazite and other rare earth-bearing feedstocks.

The company fully owns Vara Mada in Madagascar and Bahia in Brazil, while holding a 49% interest in the Donald project in Australia.

This geographic diversification could give White Mesa access to multiple sources of feedstock rather than relying solely on US mine production.

The company also plans to move further downstream through the proposed acquisition of Australian Strategic Materials.

That transaction would support development of the American Metal Plant in the US, with initial rare earth alloy capacity of 2,000 t/yr and potential expansion to 4,000 t/yr.

Permitting is expected to continue through 2026, followed by a two-year construction period.

If these projects proceed as planned, Energy Fuels could control a supply chain extending from mineral sands and monazite through separated oxides to rare earth metals and alloys.

The Metalnomist Commentary

Energy Fuels is building one of the more complete non-China rare earth chains in the US. The key strategic value lies in linking diversified monazite feedstock with heavy rare earth separation and domestic alloy production.
