Energy Fuels’ Donald Rare Earth and Mineral Sand Joint Venture in Australia Receives Final Major
Regulatory Approvals
The Donald Project, a JV between Energy Fuels and Astron Corporation, is considered one of the World’s
best near-term sources of rare earth minerals, which Energy Fuels intends to process into “light”, “mid”
and “heavy” rare earth oxides at its White Mesa Mill in Utah.
DENVER, June 25, 2025 — Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) (“Energy Fuels” or the
“Company”), a leading U.S. producer of uranium, rare earth elements (“REEs”), and other critical minerals,
is pleased to announce that the Government of Victoria, Australia has approved the Work Plan for the
construction and operation of the Donald Rare Earth and Mineral Sand Project ( the “Donald Project”)
located in the Wimmera region of Victoria.
This is the final major regulatory approval required to construct and operate the Donald Project. It enables
the finalization of critical activities, including arrangements for debt and equity financing, before a final
investment decision (“FID”) can be made.
The Donald Project is a joint venture (“JV”) between US-based Energy Fuels and Australia-based Astron
Corporation Limited (“Astron”), under which Energy Fuels has the right to invest a total of AU$183 million
(US$119 million at current exchange rates), plus issuance of US$17.5 million of common shares, to earn
up to a 49% interest in the project. The Donald Project is expected to provide Energy Fuels with a low-cost
and long-term allied supply of monazite- and xenotime-bearing REE mineral concentrate (“REEC”), which
the Company plans to import into the U.S. for processing into high-purity separated REEs at the Company’s
White Mesa Mill in Utah (the “ Mill”), including neodymium -praseodymium (“ NdPr”), terbium (“ Tb”),
dysprosium (“Dy”), and potentially samarium (“Sm”) and others.
Mark S. Chalmers, President and CEO of Energy Fuels stated: “The Work Plan approval for the Donald
Project is significant as it moves us one step closer to creating an important link between the United States
and Australia on rare earths and critical minerals . We believe the Donald Project is exceptional, as it
contains large quantities of the ‘light’, ‘mid’ and ‘heavy’ rare earth oxides needed for a variety of
commercial, clean energy and defense technologies. Energy Fuels plans to import the rare earth minerals
from the Donald Project into the USA, where we will p rocess them into separated oxides at our Mill in
Utah for domestic and other customers.”
Once in operation, the Donald Project JV will sell: (i) all the REEC to Energy Fuels at then-prevailing market
prices and (ii) the titanium and zircon heavy mineral sand concentrate (“HMC”) to Astron or other global
customers. Following payment of all JV expenses, all profits from the JV will be distributed to Energy Fuels
and Astron, pro rata according to their respective ownership interests. This arrangement is expected to
provide Energy Fuels with a low -cost and large-scale source of REE feedstock for se veral decades. This
June 3, 2024 news release describes additional terms of the JV.
Phase 1 of the Donald Project is expected to supply Energy Fuels with approximately 7,000 – 8,000 metric
tons (“tonnes”) of REEC per year (“Donald – Phase 1”), commencing as early as 2026 . 8,000 tonnes of
REEC from the Donald Project would contain approximately 4,700 tonnes of total REE oxides (“ TREO”),
including roughly 990 tonnes of separated NdPr, 84 tonnes of Dy oxide, and 14 tonnes of Tb oxide. Energy
Fuels has the current installed “Phase 1” capacity at the Mill in Utah to process the Donald – Phase 1
quantities of REEC into separated NdPr, along with a samarium -plus (“Sm+”) REE concentrate. The Sm+
concentrate would be stockpiled at the Mill for future processing into separated “mid” and “heavy” REE
oxides in the planned Phase 2 expansion of the Mill (the “Phase 2 Mill Expansion”).
As soon as practicable after commencing the Donald – Phase 1 commercial production, Energy Fuels and
Astron expect to evaluate constructing Phase 2 of the Donald P roject, which would be expected to
increase production to approximately 13,000 to 14,000 tonnes per year of REEC, providing a consistent
and significant source of REE feedstock for Energy Fuels for decades to come.
As also previously reported, Energy Fuels expects to complete the Phase 2 Mill Expansion to enable the
processing of up to 60,000 tonnes of REEC into up to roughly 6,000 tonnes of separated NdPr, along with
significant quantities of Tb, Dy, and potentially Sm and other REE oxides. Therefore, the Donald Project’s
13,000 to 14,000 tonnes of REEC have the potential to fill roughly 22% - 23% of the planned capacity of
the Phase 2 Mill Expansion.
Energy Fuels and Astron are currently working towards an FID for the Donald Project, which could be made
as early as the end of 2025. The FID and development of the project could be significantly accelerated with
U.S. and/or Australian government support. With the Work Plan approval, construction on the Donald
Project could begin within weeks of a positive FID.
Energy Fuels believes the Donald Project is one of the best, near-term sources of “mid” and “heavy” REEs
needed for numerous commercial and defense applications, due to the high relative concentrations of
xenotime in the REEC. Xenotime is a phosphate mineral like monazite, which is enriched in “mid” and
“heavy” REE oxides , and is found alongside monazite in many mineral sand deposits . Monazite and
xenotime can be processed together in the Mill’s circuits.

About Energy Fuels
Energy Fuels is a leading US -based critical minerals company, focused on uranium, rare earth elements,
heavy mineral sands, vanadium and medical isotopes. Energy Fuels, which owns and operates several
conventional and in-situ recovery uranium projects in the western United States, has been the leading U.S.
producer of natural uranium concentrate for the past several years, which is sold to nuclear utilities that
process it further for the production of carbon-free nuclear energy. Energy Fuels also owns the White Mesa
Mill in Utah, which is the only fully licensed and operating conventional uranium processing facility
in the United States. At the Mill, Energy Fuels also produces advanced rare earth element products,
vanadium oxide (when market conditions warrant), and is evaluating the potential recovery of certain
medical isotopes from existing uranium process streams needed for emerging Targeted Alpha Therapy
cancer treatments. Energy Fuels is also developing three (3) additional heavy mineral sands projects: the
Toliara Project in Madagascar; the Bahia Project in Brazil; and the Donald Project in Australia in which
Energy Fuels has the right to earn up to a 49% interest in a joint venture with Astron Corporation Limited.
Energy Fuels is based in Lakewood, Colorado, near Denver, with its heavy mineral sands operations
managed from Perth, Australia. The primary trading market for Energy Fuels' common shares is the NYSE
