Energy Fuels Achieves Commercial Production of ‘On-Spec’ Separated Rare Earths at its White Mesa

Mill in Utah, While Simultaneously Advancing Uranium Production

LAKEWOOD, Colo., June 10, 2024 /CNW/ - Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) ("Energy

Fuels" or the "Company" ), a leading U.S. producer of uranium, rare earth elements (“ REEs”), and

vanadium, is pleased to announce that it has achieved commercial production of separated neodymium-

praseodymium (“NdPr”) at its White Mesa Mill in Utah (the “Mill”). Critically, the NdPr produced by Energy

Fuels’ meets the applicable product specifications of REE metal-makers, who specialize in the manufacture

of REE-based alloys required for the permanent magnets widely used for electric motors in both battery

powered electric vehicles (“EVs”) and dual power hybrids. Further, this ‘on -spec’ NdPr is now able to be

produced by Energy Fuels at the full design capacity of its new Phase 1 REE separation circuit (850 to 1,000

metric tons (“ tonnes”) of NdPr per year). The Company expects to have commercial quantities of

separated NdPr available for shipment by the end of June 2024. Energy Fuels believes this is the first time

in several decades that a U.S. company has produced on -spec separated REE’s from mon azite on a

commercial scale.

The Company is extracting, refining and separating the NdPr from monazite produced by The Chemours

Company (“Chemours”) at its heavy mineral sand (“HMS”) operations in Florida and Georgia. Energy Fuels

began piloting REE separations in 2021, and later performed partial REE separations in 2022 and 2023.

The Company used this experience, having compiled several years of real-time data, to custom design and

construct its new Phase 1 REE separation circuit at the Mill, which is now operating as designed . The

Company would also like to highlight both the speed at which the circuit has reached full design capacity,

and the fact that it has not experienced complications with start -up, which are so typical with the

commissioning of new equipment and processes. Energy Fuels also completed construction of its Phase 1

REE Separation Circuit in Q1-2024 for a total cost of only about $16 million, which was significantly under

the original budget of $25 million and a further testament to the capabilities of the Mill and the years of

solvent extraction (“SX”) experience and technical expertise of Mill personnel. Also of note, the addition

of REE separation processes has not hindered the ability or capacity of the Company to produce uranium

at the Mill, and preparations are being made to commence a uranium ore and alternate feed uranium-

bearing material processing campaign in Q3-2024.

During Q2-2024, the Company expects to produce about 25 to 35 tonnes of on-spec, separated NdPr from

the monazite Energy Fuels has in inventory at this time. From the new circuit, Energy Fuels also expects

to produce a samarium -plus (“ Sm+”), “heavy” REE concentra te, while also recovering the contained

uranium from the monazite feed stocks. The Company expects to utilize this Sm+ concentrate to continue

2

pilot-scale dysprosium (“Dy”) and terbium (“Tb”) separation and to design SX circuits at the Mill able to

produce these “heavy” REE products in separated individual forms at the specifications required for metal

and alloy making. Currently, there is no company in the Western Hemisphere capable of commercially

producing separated, on-spec Dy, Tb, or other “heavy” REE products. NdPr, Dy, and Tb are known as the

“magnet” REE’s, as they ar e key and necessary ingr edients in the powerful magnets used in the most

efficient EVs, dual power hybrid vehicles, direct-drive wind energy, military and defense technologies, and

other clean energy applications.

Following completion of NdPr production at the Mill in Q2-2004, the Company expects to begin processing

uranium ore and alternate feed materials from our current stockpiles, resulting in the expected

production of 150,000 to 500,000 pounds of U 3O8 during 2024, with production ramping up further in

2025. As previously announced, Energy Fuels has also acquired, or is in the process of acquiring, several

HMS projects to secure monazite, which we believe will be globally cost-competitive, to supply future REE

separation at the Mill. This includes the Bahia Project in Brazil that the Company acquired in February

2023, the Donald Project joint venture that the Company announced on June 3, 2024 , and the pending

acquisition of Base Resources and the Toliara Project in Madagascar, which in aggregate have the

potential to make Energy Fuels one of the largest separated REE producers in the world. T he Company

expects to receive material quantities of monazite from these projects commencing as early as 2026. In

the meantime, the Company plans to focus operations on an aggressive campaign of uranium production

during the second half of 2024, all of 2025, and thereafter to supply U.S. uranium into the Company’s

portfolio of uranium contracts with U.S. nuclear utilities, in addition to additional spot and contract sales

into uranium market strength.

MARK S. CHALMERS, PRESIDENT AND CEO OF ENERGY FUELS STATED:

“We have achieved a significant milestone for the Energy Fuels, for Utah, and for the United States: the

commercial production of separated rare earths that meet applicable product specifications, while

simultaneously ramping up domestic uranium production aggressively. I wish to congratulate the entire

team at the White Mesa Mill for bringing commercial rare earth separation capabilities and expertise

back to the United States, and for achieving this major accomplishment ahead of schedule and under

budget. With this announcement, Energy Fuels can confirm the return of separated rare earth

production from monazite back to the United States after a multi-decade absence, in addition to the

return of technological know-how and expertise in this extremely important field that is critical to

national and economic security.

“Due to the overwhelming success of Energy Fuels’ Phase 1 REE separation project, Energy Fuels can

now continue to advance its rare earth initiatives with an extremely high degree of confidence. This

3

includes a potential expansion of standalone rare earth separation capabilities at the Mill to 4,000 to

6,000 tonnes of NdPr per year, along with 150 to 225 tonnes of Dy, and 50 to 75 tonnes of Tb, through

development of our planned Phase 2 and Phase 3 REE separation circuits. While our recently

commissioned Phase 1 Separation circuit is globally significant and would rank the Company as one of

the leading producers of separated REEs in the world outside of China, our planned Phase 2 and Phase 3

Separation Circuits would truly be world-class. In addition, we are building a world-class portfolio of

heavy mineral sand assets to control our supply of low-cost monazite. We are also ramping-up pilot

testing on ‘heavy’ rare earth separation, with a focus on Dy and Tb. Due to knowledge gained from

NdPr, we are confident we will be able to produce on-spec Dy, Tb, and any other separated rare earth

products and to design, engineer, permit, construct and commission our Phase 2 and Phase 3 REE

separation circuits within budget and time-frame expectations. Our capital investments in the planned

Phase 2 and Phase 3 REE separation circuits will be conditional on receipt of suitable customer and/or

government backing in the form of supply agreements, offtake agreements and/or financial support. We

believe we are in an enviable position to secure this support, based on our proven rare earth processing,

refining and separation capabilities and the world-class monazite supply chain we have secured and are

securing. I am very pleased that all things are coming together and that we are emerging as a leading

U.S. rare earth producer, in addition to advancing our position as a U.S-leading producer of uranium and

vanadium.

“Once we conclude this run of separated NdPr, we plan to focus on the processing of our substantial

stockpiled uranium ore and alternate feed material inventories at the Mill and the continued ramp-up of

our uranium mining, production and sales. At the same time, we plan to design and permit a world-class

expansion of REE separation at the Mill -- which is only about four to six times greater than what we

have already achieved. Importantly, we will also continue to market our REE products to customers and

evaluate government funding collaborations.”
