Export Finance Australia issues Conditional Letter of Support for

the Donald Project

DENVER

,

Oct. 20, 2025

/CNW/ - Energy Fuels Inc. (NYSE American: UUUU) (TSX: EFR) (

Energy Fuels

) and Astron Limited (ASX: ATR)

(

Astron

) are pleased to announce that they have received a non-binding and conditional Letter of Support from Export Finance

Australia (

EFA

) (dated

21 October 2025

), for up to

A$80 million

in respect of senior debt project financing for the development of the Donald

Rare Earth and Mineral Sands Project (

Donald Project

). The Donald Project total funding requirement is estimated to be A$520mm based on

the latest project parameters released in

July 2025

, The joint venture is targeting a 50%: 50% debt-to-equity gearing ratio and is working with

other Export Credit Agencies and senior lenders to confirm the syndicate that will provide the project financing facility for the Donald Project.

EFA is

Australia's

export credit agency, providing commercial finance for export trade and overseas infrastructure development. The EFA

Letter of Support is subject to the satisfactory completion of due diligence, including financial, technical, environmental, and social

assessments, as is customary for facilities of this nature, credit, risk and legal approvals, and compliance with applicable laws and regulations.

The letter represents a key milestone in progressing the Project's debt financing plan and complements Astron's and Energy Fuels' broader

funding initiatives, including the Donald Project Joint Venture equity funding.

The shovel ready Donald Project is one of

Australia's

most advanced critical mineral projects, targeting the production of rare earth elements

(

REEs

), which are expected to be shipped to Energy Fuels' mineral processing facility in the U.S. for production of advanced REE materials,

and zircon-rich heavy mineral concentrates for global supply chains. Production is planned to commence as early as H2 2027, subject to

securing project financing and completion of a positive final investment decision (

FID

) for the Project.

With 100% of the Project's Rare Earth Element Concentrate (

REEC

) subject to a life-of-mine offtake agreement with Energy Fuels, the Donald

Project, once developed and brought into production, will strengthen global supply chain resilience for Western and partner nations.

When in production, Phase 1 of the Donald Project is expected to produce on average 7.2 thousand tonnes (

ktpa

) of REEC per annum

containing both light and highly strategic heavy rare earths, including up to 1,000t of Neodymium-Praseodymium (

NdPr

) oxides, 92t of

Dysprosium (

Dy

) oxide, and 16t of Terbium (

Tb

) oxides per year. Energy Fuels' White Mesa Mill (

Mill

) in

Utah, USA

has the current capacity

to process all of the Donald Project's Phase 1 REEC production and extract the light and heavy REEs. The Mill also has the current capacity to

produce up to 1,000t of separated NdPr oxide, and Energy Fuels expects to commission the capacity to produce separated Dy, Tb, and

potentially other heavy REE oxides as soon as late 2026.

Notably, the heavy rare earths expected to be produced from Donald Phase 1 would satisfy approximately one third of U.S. demand for Dy

and a quarter of U.S. demand for Tb, elements that are critical to the clean energy, defence and advanced manufacturing industries.

The financing activities are being progressed in parallel with early site works and sourcing and procurement of long-lead time equipment.

Astron Managing Director, Tiger Brown, said:

"The conditional and non-binding Letter of Support from EFA highlights the strategic role the Project plays in the diversification of critical

mineral supply chains. It marks a key milestone in our pathway to development of the Donald Project and the tangible progress we are making

toward establishing a world-class rare earth operation in

Australia

."

Energy Fuels CEO,

Mark Chalmers

, said:

"The conditional and non-binding Letter of Support from EFA is a strong vote of confidence for the Donald Project and its role in supporting

global critical minerals supply chains. This is a key additional step in our financing pathway and reflects our on-going progress toward

delivering one of

Australia's

most important rare earth projects, including valuable NdPr, and exceptional concentrations of Dy, Tb and other

'heavy' rare earth oxides, which upon project development will be processed and separated into high-purity products at our White Mesa Mill in

Utah

."

Broader Financing Strategy

The conditional and non-binding Letter of Support from EFA complements the companies' broader financing strategies for the Donald Project,

which includes:

Advanced ongoing engagement with other government agencies and commercial banks to secure the balance of the debt financing.

A staged equity investment of up to

A$183 million

from Energy Fuels, of which

A$45 million

is expected to be contributed prior to FID and

A$138 million

is expected to be contributed post-FID, providing capital for pre-development and construction activities.

Pro-rata equity contributions by the joint venturers on a 51%/49% basis amounting to additional post-FID contributions of

A$122 million

(of

which Astron's share would be

~A$62 million

and Energy Fuels' share would be

~A$60 million

).

These financing arrangements collectively represent material progress toward securing full funding for the development of the Donald Project.

Based on the revised project economic parameters, which were announced on

23 July 2025

, the Project's indicative forecast total funding

requirement is

A$520 million

(in nominal terms) including capital expenditures and start-up working capital, as well as

A$44 million

of indicative

finance costs, fees and interest during the construction period, and funding reserves, based on targeting a base case 50%:50% debt-to equity

ratio.

Astron will continue to work with its debt advisor, ICA Partners, on the arrangement of debt funding for the Donald Project.

This announcement is authorised for release by the Managing Director of Astron and CEO of Energy Fuels.

About Donald Project

The Donald Project, in

Victoria's

Murray

Basin near Minyip and Donald, is expected to be a globally significant source of critical minerals. The

Project features a total mineral resource of 1.81 billion tonnes with a planned mine life greater than 58 years over two phases. It will produce

zirconium, titanium, and rare earth elements, including neodymium, praseodymium, terbium and dysprosium, which support technologies vital to

clean energy, defence, and advanced manufacturing. Astron Limited and US critical minerals company Energy Fuels Inc. have formed a joint

venture, known as Donald Mineral Sands (DMS), which is developing the project. DMS is committed to responsible land use, progressive

rehabilitation, and long-term economic contribution to regional Victoria.
