Energy Fuels Announces Strategic Venture with Nanoscale Powders to

Develop Innovative Rare Earth Metal-Making Technology

Nanoscale’s patented rare earth metal-making technology has potential to revolutionize rare earth metal

making by reducing costs, significantly reducing greenhouse gas emissions, and reducing energy use

Lakewood, CO – (December 15, 2021) – Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) ("Energy Fuels"

or the “Company”) is pleased to announce the execution of a Memorandum of Understanding (“MOU”) with

Nanoscale Powders LLC (“NSP”) for the development of a novel technology (the “ Technology”) for the

production of rare earth element (“REE”) metals (the “Project”). We believe t his Technology, which was

initially developed by NSP, and will be advanced by the Company and NSP working together, has the potential

to revolutionize the rare earth metal making industry by reducing costs of production, reducing energy

consumption, and significantly reducing greenhouse gas (“GHG”) emissions. Producing REE metals and alloys

(“REE Metals”) is a key step in a fully integrated REE supply chain, after production of separated REE oxides

(“REE Oxides”) and before the manufacture of neodymium iron boron ( “NdFeB”) magnets used in electric

vehicles (“EVs”), wind generation and other clean energy and advanced technologies.

Energy Fuels is quickly building a new, environmentally friendly REE supply chain in the United States, and

the Project with NSP represents an exciting opportunity to significantly improve the REE metal -making

process and potentially provide Energy Fuels with a competitive advantage in the REE supply chain . At its

White Mesa Mill (the “ Mill”) in Utah, t he Company is currently producing mixed REE carbonate ( “REE

Carbonate”) while recovering uranium from natural monazite sands ( “Monazite”) which are produced as a

low-cost byproduct of heavy mineral sands mining in the U.S. and around the globe . Energy Fuels’ REE

Carbonate is the most advanced REE product being produced in the U.S. today. The Company is also moving

quickly toward producing REE Oxides at the Mill using proven solvent extraction (“SX”) technologies. The Mill

has over 40 years of experience producing uranium and vanadium oxides using SX technology.

Founded in 2008, NSP originally focused on producing solar quality silicon metals and refractory metal

powders, eventually turning its attention to the production of titanium and alloy powders through sodium

reduction. More recently, NSP has developed a process to create REE Metals from REE Oxides through molten

sodium reduction of anhydrous REE chloride materials in a process similar to the Kroll process (called the

“Hunter Titanium Process”) which is used for the production of titanium metals through sodium reduction.

The production of REE Metals utilizing the Technology will involve feeding anhydrous REE chloride materials,

which are free of water, into a molten sodium bath. A rapid reaction takes place between the molten sodium

and the REE chlorides. The process is highly exothermic, releasing energy, so the molten sodium acts to

2

control the rate of the reaction. The reaction products are REE Metal and sodium chloride, commonly known

as salt.

The NSP sodium reduction of REE Metals has several advantages over the industry standard REE metal making

method, which utilizes electrolytic reduction of REE oxides in molten lithium fluoride/ REE fluoride baths.

First, the NSP process does not have any associated air emissions , and therefore presents a significant

improvement over the current technology, which emits carbofluoromethane (CF4) gas, which is a powerful

GHG. Second, current estimates indicate that the NSP process is significantly cheaper to operate than the

conventional electrolytic methods , because it does not consume graphite crucible materials and utilize s

significantly less energy and labor . Finally, the NSP process requires anhydrous chloride feeds , which w e

believe can be generated directly from rich liquor streams coming from the Mill’s planned SX circuit. This

could eliminate the need for oxalate precipitation and calcination of materials destined for REE metal making.

As a result of these factors, operating cost savings are currently estimated to potentially be several times less

than conventional REE metal-making methods.

As with any new technology, risks are present which must be evaluated and addressed, including successfully

creating anhydrous chloride feeds at a commercial scale with the associated risk of elevated levels of oxygen

in the final product , and the risk of being able to successfully remove and consolidate final REE Metal

products.

NSP holds two U.S. patents and one pending patent application for the Technology, under which it has proven

the ability to produce REE Metals on a kilogram batch scale basis at the U.S. Department of Energy’s

Technology Readiness Level (“TRL”) 5. Energy Fuels’ initial investment in the Project is intended to advance

the Technology to allow for : (i) the continuous , pilot-scale production of 10 kilograms per hour of

neodymium-praseodymium (“NdPr”) metal that meets typical specifications for NdFeB magnets at TLR Level

7; (ii) the separate build of a batch reactor able to produce key minor magnet metals ( e.g., dysprosium,

terbium); and (iii) the demonstration of samarium-cobalt alloy production . The Project will be directed by

Energy Fuels with technical support from other research firms and institutions as required.

Under the MOU, the parties will negotiate and enter into binding agreements (“Definitive Agreements”) that

govern the Project, including the creation of a new entity that will hold an exclusive license to the Technology

as it relates to REE Metal making. The MOU contemplates a phased development of the Project to scale-up

to the production of 1,000 metric tonnes of one or more REE Metals per year. Energy Fuels will have the right

to earn up to a 100% interest in the entity and Technology, as it relates to REE Metal making, by making the

following capital investments:

1. US$250,000 within five (5) business days after execution of the MOU;

3

2. US$250,000 within five (5) business days after execution and delivery of the Definitive Agreements;

3. US$1 million within five (5) business days after execution and delivery of the Definitive Agreements to be

applied to the Project’s 2022 budget and work plan; and

4. Energy Fuels will fund all future approved annual budgets as may be required for commercialization of

the Project, up to a maximum additional expenditure of US$8.5 million over three (3) years , totaling

US$10 million for the Project.

Upon the successful completion of the Project and the $10 million investment, Energy Fuels will control the

exclusive rights to the entity and the Technology as it relates to REE Metal making. Energy Fuels will also have

the right to cease funding at various decision points during the Project, at which point Energy Fuels will hold

a percentage of the new entity and Technology, proportional to its amount contributed. If Energy Fuels ceases

funding prior to earning 100% of the Technology, NSP will have the right in certain circumstances to acquire

Energy Fuels’ interest in the entity and Technology by reimbursing Energy Fuels for its expenditures on the

Project.

Mark S. Chalmers, President and CEO of Energy Fuels stated: “Metal-making is a critical step in the rare earth

supply chain. Energy Fuels has already restored monazite ‘crack-and-leach’ capabilities to the U.S. at our

White Mesa Mill in Utah, where today we are producing a high-purity mixed rare earth carbonate, which is

ready for separation. No other company in the U.S. is currently producing a high -purity REE product ready

for separation at commercial levels. We are also quickly moving toward adding solvent extraction separation

equipment at the Mill and associated permitting that will allow us to produce commercial separated rare

earth oxide powders in the coming years. In fact, we are already well advanced with piloting these capabilities

on a continuous 24/7 basis at the Mill today.

“The next step in rare earth processing and refining is turning those separated rare earth oxide powders into

usable rare earth metals and alloys, particularly NdPr metal needed for NdFeB magnets used in EVs , wind

generation and other technologies. We are interested in Nanoscale Powders’ technology because we believe

it has the potential to produce REE metals at lower cost , using less energy , and producing significantly less

greenhouse gas emissions than conventional REE metal making methods. If successful, Nanoscale’s metal-

making technology could be orders of magnitude safer and less expensive than the current established

technology. This is the type of technology we as Americans need to develop to produce advanced rare earth

materials in a cost-competitive manner, while achieving the highest standards of protection of public health,

safety, and the environment. Nanoscale Powders has proven their technology on a small scale, and we look

forward to working with them to advance the technology to pilot scale, and then to commercial scale in the

coming years. Our relationship with Nanoscale Powders demonstrates Energy Fuels’ commitment to fully

integrating a domestic REE processing supply chain in the most optimal and environmentally prudent manner

possible.”
