A Further Step in the Development of a Fully Integrated U.S. Rare Earth Element Supply Chain

• Energy Fuels and Hyperion have signed a memorandum of understanding to evaluate the potential supply of monazite sands from the Titan Project in Tennessee to Energy Fuels’ White Mesa Mill in Utah for the production of rare earth products.
• Monazite is a very valuable rare earth-bearing mineral, planned to be produced at the Titan Project as a component of its heavy mineral sand concentrate product.
• The MOU highlights the potential importance of Hyperion’s Titan Project, as Energy Fuels advances its initiatives to establish a fully integrated, low-cost U.S rare earth element supply chain.
• Energy Fuels and Hyperion will also evaluate a potential arrangement to collaborate in the development of an integrated U.S. rare earth supply chain.

Energy Fuels Inc. ("Energy Fuels") (NYSE: UUUU) (TSX: EFR) and Hyperion Metals Limited (“Hyperion”) (ASX: HYM) are pleased to announce the execution of a non-binding memorandum of understanding ("MOU") for the supply of natural monazite sands (“Monazite”) from Hyperion’s Titan Project in Tennessee (the “Titan Project”). Energy Fuels plans to produce mixed rare earth element (“REE”) products from processing the Monazite at its White Mesa Mill in Utah.

The parties have also agreed to evaluate a potential teaming, joint venture, equity investment or other arrangement under which Hyperion would collaborate with Energy Fuels, and potentially other parties, in advancing Energy Fuels’ current initiative to establish a fully integrated, “mine to market” U.S. rare earth supply chain for the electric vehicle and renewable energy sectors, as well as other specialty uses.

The collaboration between Energy Fuels and Hyperion will initially focus on the potential commercial supply of Monazite from Hyperion’s Titan Project to Energy Fuels’ White Mesa Mill. Under the MOU, the parties have agreed to negotiate a definitive sales agreement for this supply of Monazite. In addition, subject to Hyperion supplying Energy Fuels with a sufficient quantity of Monazite from the Titan Project within a reasonable period of time, Hyperion and Energy Fuels will evaluate entering into a joint venture or other similar arrangement whereby Hyperion would participate with Energy Fuels, and potentially other parties, in the continuing development and operation of an integrated, low-cost and sustainable independent U.S. rare earth supply chain, under which Monazite would be supplied from The Chemours Company (NYSE: CC) (“Chemours”) U.S. projects, the Titan Project, and potentially other U.S. and international mines, with the Monazite to be processed and separated into value-added rare earth products at Energy Fuels’ White Mesa Mill. This could potentially also result in the development of rare earth metal production capabilities.

Hyperion’s Titan Project covers a large area of heavy mineral sands properties in Tennessee prospective for titanium, zircon, Monazite and other valuable minerals such as high-grade silica sand and other refractory minerals. The Titan Project is in an area which saw significant historic exploration from 1960 – 1990 by DuPont, BHP and others, strategically located in the southeast of the U.S., close to significant manufacturing capacity, providing what Hyperion believes to be a significant logistical advantage over current U.S. supplies of imported titanium feedstock.

Hyperion is nearing completion of a three-phase drilling and bulk sampling test work program at the Titan Project. Results to date have successfully confirmed the high grade and significant thickness of mineralization over approximately a 3.6 km strike length. Assays from the drill programs to date have returned thick zones of high-grade Total Heavy Mineral (“THM”) near surface, with highlights including:

• 47.2m @ 3.69% THM including 10.7m @ 8.09% THM and 10.7m @ 5.47% THM
• 36.6m @ 3.37% THM including 12.2m @ 7.65% THM
• 35.1m @ 3.04% THM including 10.7m @ 8.16% THM
• 41.1m @ 2.14% THM including 9.1m @ 5.55 THM
• 33.5m @ 2.21% THM including 12.2m @ 5.64% THM

Hyperion’s bulk sampling test work for flow-sheet development is nearing completion, and is evaluating the production of a number of mineral products, including:

• Titanium minerals – used to produce titanium metal and for the production of paint and pigments;
• Monazite – used for the production of rare earth products;
• Zircon – used for the ceramic and foundry markets; and
• High quality silica – used in float glass, solar panel glass and pharmaceutical grade glass.

A 70-hole Phase 3 drill program is nearing completion, and together with the bulk sample program will form the basis for Hyperion’s initial mineral resource estimate expected to be delivered in Q2 2021. For more information about the Titan Project go to: www.hyperionmetals.us

Energy Fuels and Neo Performance Materials Inc. (TSX: NEO) (“Neo”) recently announced the joint launch of a U.S.-European REE supply chain involving Energy Fuels, Neo and Chemours. Under this emerging initiative, Energy Fuels is currently purchasing 2,500 tons of Monazite per year from the Chemours Company’s Georgia (USA) heavy mineral sand operations. Energy Fuels is currently processing this Monazite at its White Mesa Mill in Utah into a clean, mixed REE carbonate, as well as recovering the contained uranium. Energy Fuels is selling this intermediate REE product to Neo’s REE separations facility in Sillamae, Estonia for the production of commercial value-added REE products, supplying U.S. and European markets.

In addition to producing mixed REE carbonate, Energy Fuels is also evaluating the potential to develop U.S. separation, metals, alloys, and other downstream REE capabilities at the White Mesa Mill, or nearby, thereby fully integrating a U.S. rare earth supply chain in the coming years. Energy Fuels is seeking to increase its supply of Monazite feed to approximately 15,000 tons per year (or greater) for this initiative. Subject to completion of permitting, development and commencement of operations, the Titan Project is expected to be a potential future source of Monazite to supplement Chemours’ supply of Monazite to Energy Fuels.

The MOU highlights the importance of Hyperion’s Titan Project as a potentially important source of high value American rare earth minerals, expected to play an integral role in rebuilding sustainable, robust and resilient transportation, energy and defense sectors, and the desire of Energy Fuels to build diversified and significant Monazite feedstocks from various sources.

Energy Fuels’ President and Chief Executive Officer, Mr. Mark Chalmers, said: “Energy Fuels, along with Chemours and Neo, are creating a new U.S.-Europe rare earth supply chain. For this initiative to achieve its full potential, we are actively seeking new, ethically-produced sources of Monazite, with sources from the U.S. being our first priority. Therefore, we are excited to work with Hyperion to secure additional sources of Monazite for processing at the White Mesa Mill. Through their association with Piedmont Lithium’s project in South Carolina, members of the Hyperion team have demonstrated to us that they have the know-how and resources to bring U.S. critical mineral projects into production. We look forward to working with the Hyperion team and potentially seeing our relationship grow through their participation in a fully-integrated, low cost U.S. rare earth supply chain in the future. We are particularly excited about the prospect of sourcing U.S. mined Monazite, which together with our current supplies from Chemours’ Georgia operations and the unique capabilities of the White Mesa Mill, demonstrates to us that a world-competitive and world-scale, fully integrated U.S. rare earth supply chain is becoming a reality.”

Hyperion’s Managing Director, Mr. Anastasios Arima, said: “We are excited to progress the potential supply to Energy Fuels of American Monazite for its rare earths supply chain right here in the USA, bringing back sustainable American industry and skilled jobs for generations. The import dependence of the U.S. for key critical minerals, including rare earths and titanium, presents a huge threat to the security of key domestic industries, including defense, space, aerospace, renewables and electric vehicles. Our collaboration with Energy Fuels highlights the importance of Hyperion’s Titan Project in the U.S. as a leader in American sourced critical minerals through its plans to produce zero carbon titanium metals, delivering a clean energy future through the supply of rare earth elements for electric vehicles and the renewable power sectors.”

This announcement has been authorized for release by Hyperion’s Managing Director.
