Energy Fuels Awarded Contract to Sell $18.5 Million of Uranium to U.S. Uranium Reserve

- DOE program supports critical domestic clean energy & national security priorities

- Pending membership in DOE HALEU Consortium to support fuel for next generation advanced nuclear

reactors

December 16, 2022

Energy Fuels Inc. (NYSE American: UUUU; TSX: EFR) (“Energy Fuels” or the “Company”) , a leading U.S.

producer of uranium and rare earth elements (“ REE”), today announced that it has been awarded a

contract to sell $18.5 million of natural uranium concentrates (“ U3O8”) to the U.S. government for the

establishment of a strategic uranium reserve (the “Uranium Reserve”). The U.S. National Nuclear Security

Administration (“NNSA”), an office within the U.S. Department of Energy (“DOE ”), is the agency tasked

with purchasing domestic U3O8 and conversion services for the Uranium Reserve. The Uranium Reserve is

intended to be a backup source of supply for domestic nuclear power plants in the event of a significant

market disruption. Additionally, the Company announced its application for membership in the DOE’s

newly created HALEU Consortium.

Uranium Reserve Award:

Energy Fuels expects to complete the sale of uranium for the Uranium Reserve to NNSA during Q1-2023

and realize total gross proceeds of $18.5 million . The U 3O8 the Company expects to sell to the U.S.

government is currently held in the Company’s i nventory at the Metropolis Works Conversion Facility,

located in Metropolis, Illinois. The sale does not involve the physical movement of material, so the sale

and transfer can be completed quickly.

Mark S. Chalmers, President and CEO of Energy Fuels stated: “Energy Fuels is pleased to contribute to U.S.

energy security by supplying U.S.-origin uranium to the U.S. uranium reserve. Russia’s invasion of Ukraine

has highlighted America’s troubling dependence on Russia and its allies for our nuclear fuel and uranium

supply, and the need for the U.S. to rebuild its uranium and nuclear fuel capabilities. Today, nuclear energy

provides the U.S. with roughly 20% of all electricity, and 50% of our clean, carbon-free electricity. U.S. and

European nuclear industries are actively working to shift away from Russian uranium supply, but the

process will be difficult and lengthy. The U.S. can rely on supply from allies like Canada, Australia and others

for a large pro portion of our uranium and nuclear fuel supply, but we must also restore our own

2

capabilities. For the past several years, U.S. uranium production has been near-zero and our only uranium

conversion facility has been shut -down. The Uranium Reserve is a small, but important, step toward

resolving this untenable situation.”

HALEU Consortium:

On December 12, 2022, Energy Fuels also applied for membership in the DOE’s newly created HALEU

Consortium. The HALEU Consortium is a program managed by the DOE’s office of Nuclear Energy (“NE”)

intended to help create a secure domestic supply of high-assay, low-enriched uranium (“HALEU”) used by

many of the next generation of advanced nuclear reactor technologies. HALEU enables many advanced

reactor designs to be smaller and more efficient than traditional reactors. The uranium used in traditional

nuclear reactors is enriched to roughly 3% - 5% of the fissionable isotope, uranium-235 (“U-235”). HALEU

is enriched to between 5% and 20% U-235. Today, only Russian companies are able to supply HALEU, which

is causing delays in the development of advanced reactors. For example, TerraPower recently announced

a delay in building its first Natrium reactor in Wy oming. TerraPower is a high -profile next generation

advanced reactor developer funded by Bill Gates. TerraPower specifically attributed the delay to the lack

of availability of HALEU outside of Russia.

As the leading producer of U3O8 in the U.S., and the owner and operator of the only conventional uranium

mill in the U.S., Energy Fuels believes it can play an important role in advising the DOE and teaming with

other companies for this critical program. Furthermore, Energy Fuels is pursuing other DOE priorities

related to uranium production, including rare earth element and medical isotope production.

Mr. Chalmers continued: “Energy Fuels is increasingly recognized by the U.S. government and other market

participants as indispensable to weaning the U.S. off of Russian uranium supply, and as a solid partner in

other important priorities. Our White Mesa Mill is critical and unique domestic infrastructure, with

licenses, expertise and capabilities found nowhere else in the U.S., that are needed to produce uranium,

and many other critical minerals and materials. We stand ready to play a critical role in restoring America’s

uranium, rare earths, and other critical material capabilities, while reducing our troubling dependence on

Russia and China.”

About Energy Fuels: Energy Fuels is a leading U.S. -based uranium mining company, supplying U 3O8 to

major nuclear utilities. The Company also produces vanadium from certain of its projects, as market

conditions warrant, mixed rare earth element carbonate ( “RE Carbonate ”) from uranium -bearing

monazite ores and is ramping up to full commercial -scale production of separated rare earth oxides. Its

corporate offices are in Lakewood, Colorado near Denver, and all its assets and employees are in the United

States. Energy Fuels holds two of America’s key uranium production centers: the White Mesa Mill in Utah

3

and the Nichols Ranch ISR Project in Wyoming. The White Mesa Mill is the only conventional uranium mill

operating in the U.S. today, has a licensed capacity of over 8 million pounds of U3O8 per year, and has the

ability to produce vanadium when market conditions warrant, as well as RE Carbonate from various

uranium-bearing ores. The Nichols Ranch ISR Project is currently on standby and has a licensed capacity of

2 million pounds of U3O8 per year. In addition to the above production facilities, Energy Fuels also has one

of the largest S -K 1300 and NI 43 -101 compliant uranium resource portfolios in the U.S. and several

uranium and uranium/vanadium mining projects on standby and in various stages of permitting and

development. The primary trading market for Energy Fuels’ common shares is the NYSE American under

the trading symbol “UUUU,” and the Company’s common shares are also listed on the Toronto Stock

Exchange under the trading symbol “EFR.” Energy Fuels’ website is www.energyfuels.com.
