Energy Fuels Inc. (NYSE American: UUUU; TSX: EFR) (“Energy Fuels”), the leading producer of uranium in the United States, is pleased to announce that it has entered into consulting agreements with Constantine Karayannopoulos and Brock O’Kelley, two rare earth element (“REE”) industry experts who each have decades of experience producing commercially viable rare earth products, to aid in the development and implementation of commercial and technical REE strategies for the new U.S. REE program Energy Fuels is pursuing.

A chemical engineer by training with more than 25 years of experience in the rare earth industry, Mr. Karayannopoulos is Chairman of Neo Performance Materials (TSX:NEO), one of the world’s leading producers of rare earth engineered and magnetic materials, with integrated supply chains across the globe. Mr. O’Kelley played a key role in the operation of the Mountain Pass, California rare earth processing facility during the 1990s and 2000s. Both are industry veterans with extensive knowledge of REE processing facility design, start-up, operations, and downstream value-added manufacturing of advanced REE products.

Energy Fuels is currently evaluating minor modifications to its operations, complementary to its uranium business, to enable the processing uranium- and thorium-bearing rare earth ores at its fully licensed and operational White Mesa Mill (the “Mill) in Utah. These ores are expected to come from third parties, either through ore purchase, tolling, or other arrangements, and Energy Fuels expects to produce a commercially viable rare earth concentrate or concentrates, while also recycling and recovering uranium from these ores. The rare earth concentrates would then be available for commercial sale to third party REE oxide separation and recovery facilities in the U.S. and elsewhere, and/or potentially for further refinement and REE separation and recovery at the Mill.

Removal and recovery of the uranium and thorium from rare earth ores is the key aspect of Energy Fuels’ value proposition, as many rare earth separation and recovery facilities are not able to handle uranium or thorium from a technical or regulatory standpoint. The White Mesa Mill has a 40 year history of responsibly handling, processing and recycling uranium and thorium bearing materials. Therefore, it has the potential to provide a crucial link in a commercially viable U.S rare earth supply chain. It should be noted that Energy Fuels intends to continue to focus on its current uranium mining and production operations, and possibly enhance that production by recovering the contained uranium from REE ores for sale into the nuclear fuel cycle.

Presentation at Mining Conference:  Energy Fuels is also pleased to announce that CEO Mark Chalmers will be a keynote speaker at today (Thursday, May 21, 2020) at 1:30 pm Eastern. Mr. Chalmers intends to discuss this rare earth opportunity further.

“Energy Fuels is extremely excited to bring Constantine Karayannopoulos and Brock O’Kelley on board to advance our entry into the rare earth space in the U.S.,” stated Mark S. Chalmers, President and CEO of Energy Fuels. “Over the past year or so, Energy Fuels has been actively evaluating this rare earth opportunity. We are quickly coming to the conclusion that the White Mesa Mill may be an ideal U.S. facility to process rare earth element ore streams and produce rare earth concentrates. Mr. Karayannopoulos and Mr. O’Kelley will assist Energy Fuels in the commercial and technical aspects of this endeavor. Mr. Karayannopoulos established Neo Material Technologies into a unique REE materials company, which is currently one of the World’s leading producers of REEs and a broad range of light and heavy rare earth engineered products outside of China. Neo was acquired for Cdn$1.3 billion in 2012 by Molycorp, the operator of the rare earth mine and processing facility in Mountain Pass, California. Neo maintained its cash flow and profitability, despite Molycorp’s 2015 reorganization. Mr. O’Kelley worked with Mr. Karayannopoulos at Molycorp as Technology Fellow and Vice President of Technology. He is currently an associate professor at the Colorado School of Mines working with REE related projects. Energy Fuels looks forward to working with these two industry veterans in developing our REE business in the U.S. and in advancing our relationships in this sector. Between Mr. Karayannopoulos, Mr. O’Kelley, and ANSTO of Sydney, Australia, we believe Energy Fuels is truly assembling a top flight team capable of building a successful U.S. REE business.”

Mr. Chalmers continued: “We are also very excited about how this project will further the Company’s sustainability program, which we believe is one of Energy Fuels’ defining features and what sets us apart from our peers. At Energy Fuels, we are proud to be able to say that the very heart of our business – uranium production at state-of-the-art U.S. processing facilities – helps address global climate change, reduces air pollution, and makes the world a healthier and cleaner place. Uranium is the fuel for carbon-free, emission-free baseload nuclear power – one of the cleanest forms of energy in the world. We also recycle uranium and vanadium, thereby helping to ensure that the world’s resources are not wasted. Under our planned U.S. rare earth business, we will not only be recycling uranium from rare earth ore streams that would otherwise be lost, we will be helping to produce rare earth elements, which are key components of numerous modern technologies. From a sustainability perspective, not only will Energy Fuels provide critical rare earth elements used in many advanced technologies and clean energy applications, we will also provide recycled uranium to fuel carbon-free nuclear energy and power these technologies. This is a remarkable clean energy story.”

About Constantine Karayannopoulos

Mr. Karayannopoulos is currently the Chairman of the Board of Neo Performance Materials Inc. (“Neo”), a position he has held since 2016.
