Energy Fuels Announces Strategic Alliance with RadTran, LLC for the Recovery of Isotopes Needed for Emerging Cancer Therapeutics

Alliance has the potential to develop commercial technologies and sources of isotopes needed for a new domestic medical supply chain

Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) ( "Energy Fuels" or the "Company" ) is pleased to announce the execution of a Strategic Alliance Agreement ( "Alliance" ) with RadTran, LLC ( "RadTran" ) to evaluate the recovery of thorium, and potentially radium, from the Company's existing rare earth carbonate (" RE Carbonate ") and uranium process streams for use in the production of medical isotopes for emerging targeted alpha therapy (" TAT ") cancer therapeutics. This initiative will complement the Company's existing uranium and RE Carbonate businesses, as it will investigate the recovery of isotopes in existing process streams at Energy Fuels' White Mesa Mill in Utah (the "Mill" ) for medical purposes. RadTran is a Denver, Colorado -based technology development company focused on closing critical gaps in the procurement of medical isotopes for these applications.

Uranium and thorium are long-lived (long "half life"), naturally occurring radioactive elements that decay into a series of different elements through the successive loss of alpha or beta particles. Certain elements in or derived from the uranium and thorium decay chains have short half-lives and emit alpha particles. These alpha emitting isotopes are currently being studied by major pharmaceutical companies developing therapies to treat cancer on a cellular level, while minimizing damage to surrounding healthy tissue. However, existing domestic and global supplies of these isotopes are in short supply, and existing methods of production are costly and currently unable to scale-up to meet widespread demand as new drugs are developed and approved in the U.S., Europe and around the World. These are major roadblocks in the research and development of new TAT drugs, as pharmaceutical companies wait for scalable and affordable production technologies to become available.

The Mill can represent a possible solution to this medical supply chain issue. The Mill is the only licensed and operating conventional uranium mill in the U.S., and it recently began production of RE Carbonate from natural monazite sands. Monazite sands, natural uranium ores, and certain other feed sources for the Mill contain thorium-232 ( "Th-232" ) and radium-226 ( "Ra-226" ), which would normally be disposed of permanently in the Mill's tailings impoundments following processing for uranium and RE Carbonate recovery. As an initial step in this medical isotope initiative, Energy Fuels and RadTran will evaluate the technical and economic feasibility of recovering Th-232, and potentially Ra-226, from the Mill's natural monazite and other existing feeds, subject to receipt of any required licenses, permits and regulatory approvals. These isotopes are a necessary precursor to the specific medical isotopes needed by pharmaceutical companies for their emerging TAT cancer therapeutics, making this initiative the potential beginning of an important new domestic medical supply chain.

If this initial step is feasible, and subject to receipt of any required licenses, permits and regulatory approvals, Energy Fuels and RadTran will then evaluate the feasibility of recovering radium-228 ( "Ra-228" ) from the Th-232 and thorium-228 ( "Th-228" ) from the Ra-228 at the Mill using RadTran technologies, with the backing of the Pacific Northwest National Laboratory ( "PNNL" ) in Richland, Washington . The recovered Ra-228, Th-228, and potentially Ra-226, would then be sold to pharmaceutical companies and others to produce the short-lived isotopes which are the leading medically attractive TAT isotopes for the treatment of cancer, including lead-212 ( "Pb-212" ), actinium-225 ( "Ac-225" ), bismuth-213 ( "Bi-213" ), radium-224 ( "Ra-224" ), and radium-223 ( "Ra-223" ).

"The Alliance between Energy Fuels and RadTran is remarkable as it aims to alleviate the major bottleneck in the targeted alpha therapy market. Upon the successful production of these isotopes at the Mill, this Alliance will allow pharmaceutical companies who are devoping targeted alpha therapies to progress through clinical trials and deploy therapeutics commercially without the hinderance of isotope supply," stated Dr. Saleem Drera , Founder and CEO of RadTran.

If successful, this Alliance has the potential to generate significant future cashflow for Energy Fuels in the medical isotope industry. In addition, Energy Fuels can support cancer research and the creation of a new, U.S.-based medical supply chain that adheres to the highest global standards for human rights, sustainability, safety and environmental protection. This initiative is also highly complementary to the Company's existing businesses, as the uranium and rare earth feeds Energy Fuels currently processes contain the required thorium and radium. Energy Fuels is seeking to put these isotopes to beneficial human use, rather than losing them to permanent disposal.

"At its heart, the Energy Fuels' Alliance with RadTran is about maximizing the value and human benefit of our existing uranium and rare earth feeds at the White Mesa Mill," stated Mark S. Chalmers , President and CEO of Energy Fuels. "Energy Fuels has a long track record of ethically and responsibly processing a wide variety of naturally occurring radioactive materials at the White Mesa Mill for the recovery of uranium, and more recently, rare earths. In our view, recovering medical isotopes from these same streams, that would otherwise be lost to direct disposal, is a great way to maximally use all of our feeds. Indeed, we are essentially replicating China's 'monazite plan.' China purchases monazite from around the globe, recovers the uranium for use in their nuclear industry, recovers the thorium presumably for use in their nuclear and pharmaceutical industries, and recovers the rare earths for processing into advanced materials needed for various clean energy and advanced technologies. Our White Mesa Mill is a facility unique to the United States that has the potential to do the same thing at world standards.

"We believe Energy Fuels has the potential to create a domestic supply of thorium and possibly radium that can be harvested using RadTran's technologies for use in the production of the next generation of cancer therapies, a potentially multi-billion dollar industry. And we would be accomplishing this in a way that is environmentally beneficial and highly congruent with Energy Fuels' recycling and sustainability goals. We look forward to working with RadTran on this important initiative."
