Ucore Comments on China’s Immediate

Restrictions on Rare Earth Exports

Halifax, Nova Scotia ( April 4, 2025) – Ucore Rare Metals Inc. (TSXV: UCU) (OTCQX:

UURAF) (“Ucore” or the “Company”), acknowledges the recent joint announcement by

China’s Ministry of Commerce and the General Administration of Customs regarding export

restrictions on critical rare earth elements effective April 4, 2025.

As reported by multiple news sources , the export restrictions , applicable to all countries,

include seven key medium and heavy rare earth elements, including samarium, gadolinium,

terbium, dysprosium, lutetium, scandium and yttrium.

China's decision to implement these export controls underscores the critical importance of

establishing a secure and independent rare earth supply chain in North America. Ucore

remains steadfast in its commitment to mitigating supply chain vulnerabilities through the

development and commercialization of its proprietary RapidSX™ rare earth element refining

technology.

Ucore's Strategic Initiatives:

• U.S. Department of Defense Collaboration : Ucore is currently processing heavy

rare earth elements at its RapidSX ™ Commercial Demonstration Plant (the

“Demonstration Plant”) further to its USD$4 million contract with the US Department

of Defense. The Demonstration Plant was constructed in Kingston, Ontario for the

purpose of demonstrating the RapidSX™ technology at commercial scale.

• Louisiana Strategic Metals Complex (SMC): Ucore is progressing with the

development of the Louisiana SMC in Alexandria, Louisiana. This facility is being

designed to process broad both heavy and light mixed rare earth chemical

concentrates, thereby reducing North America's reliance on foreign sources.

• Government Support: Ucore has additionally secured a $4.28 million funding

agreement from the Government of Canada to demonstrate the commercial efficacy

of the RapidSX™ technology. This funding supports the production of high-purity rare

earth elements from Canadian and U.S. feedstock sources. In addition to federal

government support, the Company has executed a non -binding Letter of Intent with

the State of Louisiana with respect to State grants, tax incentives, payroll rebates and

other incentives with an estimated value of USD$15 million.

On March 20, 2025, President Trump invoked wartime powers under the Defense

Production Act to address threats to America’s national and economic security as a result

of reliance on “hostile foreign powers’ mineral production” (see Ucore Press Ucore

Applauds White House Executive Action to Strengthen Critical Mineral Production – Ucore

Rare Metals Inc. ). The Executive Order outlines a number of initiatives to “facilitate

domestic mineral production to the maximum extent possible” and is aimed at the

production of a number of critical minerals, including rare earth elements. Ucore looks

forward to contin uing its work the US Department of Defense in developing a North

American supply chain for these critical materials.

Pat Ryan, P.Eng., Chairman and CEO of Ucore, stated: "China's recent announcement

highlights the urgent need for a robust and independent rare earth supply chain in North

America. Ucore's RapidSX ™ technology offers a transformative solution to this challenge,

and we are committed to advancing our strategic initiatives to ensure a stable and secure

supply of critical rare earth elements."

Metals Complexes (“SMCs”). Ucore has also assumed that sufficient external funding will be

found to complete the Demo Plant demonstration schedule and also late r prepare a new

National Instrument 43-101 (“NI 43-101”) technical report that demonstrates that the Bokan

Mountain Rare Earth Element project (“Bokan”) is feasible and economically viable for the

production of both REE and co -product metals and the then p revailing market prices based

upon assumed customer offtake agreements. Ucore has also assumed that sufficient external

funding will be secured to continue the development of the specific engineering plans for the

SMCs and their construction. Factors that could cause actual results to differ materially from

those in forward -looking statements include, without limitation: IMC failing to protect its

intellectual property rights in RapidSX ™; RapidSX ™ failing to demonstrate commercial

viability in large commerc ial-scale applications; Ucore not being able to procure additional

the specific design and construction of the SMCs and/or the continued development of

RapidSX™; adverse capital -market conditions; unexpected due -diligence findings; the

emergence of alternative superior metallurgy and metal-separation technologies; the inability

of Ucore and/or IMC to retain its key staff members; a change in the legislation in Lo uisiana

or Alaska and/or in the support expressed by the Alaska Industrial Development and Export
