Energy Fuels Achieves Major Environmental Milestone at its Alta Mesa Uranium

Project in Texas

Denver, Colorado – March 29, 2018

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

leading uranium producer in the U.S., is pleased to announce that it has achieved a major

environmental milestone at its Alta Mesa Uranium Project (“Alta Mesa”) in Texas. On March 16,

2018, the Company receiv ed a notice from the Texas Commission on Environmental Quality

(“TCEQ”) confirming that the Company accomplished final groundwater restoration at

Production Area 1 (“PAA1” ). Now that TCEQ has deemed wellfield restoration complete, the

Company can proceed to well plugging and final closure of PAA1, including a reduction of the

reclamation bond on the project and the return of restricted cash. Groundwater restoration

following uranium recovery is one of the most important environmental compliance milestones

that every U.S. in situ recovery (“ISR”) facility must complete following production.

Mark S. Chalmers, President and CEO of Energy Fuels stated: “We are extremely proud to

receive government confirmation of final restoration of the wellfield at Alta Mesa. Energy Fuels

and the rest of the U.S. uranium industry operate under the highest health, safety, and

environmental standards in the world, including state-of-the-art protection of groundwater and

drinking water. This is a major milestone for Energy Fuels and further proof of our commitment

to environmental stewardship. I congratulate our team on the ground in Texas and the support

staff here in Denver for their hard work and professionalism on this important achievement.”

Alta Mesa is a fully -permitted and constructed ISR uranium project located in South Texas. The

project (including PAA1) was in production from 2005 until 2012, during which time it produced

approximately 4. 6 million pounds of U3O8, or enough uranium to provide clean, carbon- free

electricity from an average sized nuclear reactor for a little over eight years . At the current

time, Alta Mesa is being maintained by the Company on standby status, ready to resume

operations within approximately 12 months of a production decision . In order to resume

production, the Company would need to complete minor facility improvements and install new

wellfields. Alta Mesa has a total project area of approximately 200,000 acres, including a

licensed and constructed ISR processing plant with a total annual production capacity of 1.5

million pounds of U3O8 per year.

According to a technical report (“Technical Report ”) prepared in accordance with National

Instrument 43-101 – Standards of disclosure for Mineral Projects (“NI 43-101”), Alta Mesa holds

a total of 1.6 million tons of Measured and Indicated Mineral Resources with an average grade

of 0.111% U 3O8 containing 3.6 million pounds of uranium, along with 7.0 million tons of

2

Inferred Mineral Resources with an average grade of 0.121% U 3O8 containing 16.8 million

pounds of uranium. The Technical Report also identifies certain exploration targets that include

2.6 million tons of mineralized material with an average grade that could range from 0.077% -

0.123% U3O8. In improved market conditions , the Company expects to resume exploration

drilling on the property to expand the uranium resources and upgrade existing mineral

resources into higher categories.
