Ucore Announces Groundbreaking Ceremony for

Louisiana Rare Earth Element Processing Facility

Halifax, Nova Scotia (May 28, 2025) – Ucore Rare Metals Inc. (TSXV: UCU; OTCQX:

UURAF) (“Ucore” or the “Company”) is pleased to announce that it will hold a formal

ground-breaking ceremony on Thursday, May 29th for its Louisiana Strategic Metals

Complex (“SMC”), the Company’s first commercial rare earth element (“ REE”) refining

facility, located at the England Airpark in Alexandria, Louisiana.

The Louisiana SMC will produce high-purity rare earth oxides from mixed rare earth

chemical concentrates obtained from multiple global feedstock sources. The 80,800-

square-foot brownfield facility is under a long-term lease agreement with the

England Authority, the entity that manages England Airpark, a repurposed U.S. Air

Force base transformed into a regional economic hub.

Pat Ryan, P.Eng., Chairman & CEO, commented: “Breaking ground on the SMC is a

pivotal moment - for Ucore and for North American critical mineral processing. We are

very fortunate to have a host of strong partners at the local, regional, state, and federal

levels. This includes the England Authority, Louisiana Central, the State of Louisiana,

and the U.S. Department of Defense. We thank all of our supporters as we continue our

work to develop a secure, domestic rare earth element supply chain.”

Strategic Metals Complex (SMC) Overview

The Louisiana SMC is the first step in Ucore’s commercial deployment of the RapidSX™

technology platform, a patent-pending advanced solvent extraction process that aims

to reshape the rare earth industry with faster, more efficient, and more environmentally

sound separation methods. Once operational, the SMC will produce commercial

quantities of critical rare earth elements , such as neodymium, praseodymium,

dysprosium, and terbium, which are essential to produce rare earth permanent magnets

for electric vehicles, wind turbines, and national defense applications.

Federal and State Support

U.S. Department of Defense Funding

Ucore recently agreed on a US$18.4 million project extension from the U.S.

Department of Defense (DoD) under the Industrial Base Analysis and Sustainment

(“IBAS”) Program. This grant funding will be used to initiate construction and

equipment procurement for the Louisiana SMC. The DoD support reflects the strategic

importance of securing a domestic supply chain for rare earth materials critical to national

defense.

England Airpark

England Airpark has been a critical partner in supporting Ucore’s vision for the Strategic

Metals Complex. As the operator of the former England Air Force Base, the England

Authority has transformed the site into a thriving commercial and industrial hub. England

Airpark has provided Ucore with a strategically located, infrastructure-ready site—within

a federally designated Foreign Trade Zone ( “FTZ”). This designation allows Ucore to

benefit from potential duty deferrals, reductions, or eliminations on imported feedstock

materials, enhancing the global competitiveness of its rare earth processing operations.

Combined with collaborative local support a nd expedited permitting, the partnership

underscores England Airpark’s role in advancing U.S. critical mineral independence.

Louisiana Incentive Package

In addition to federal funding, the State of Louisiana and local partners have assembled

a US $15+ million incentive package for the Company, including:

• Industrial Tax Exemption Program (“ITEP”): up to US $8.2 million in ad-

valorem tax savings over 10 years

• Infrastructure Grant: US $900,000 for facility upgrades

• Facility Offset: US $360,000 over 24 months to reduce initial lease costs

• Additional Support Includes: payroll rebates, LED FastStart™ workforce

training, and expedited state permitting

These incentives underscore Louisiana’s commitment to establishing Alexandria as a

key node in North America’s emerging critical mineral supply chain.

About Ucore Rare Metals Inc.

Ucore is focused on rare - and critical -metal resources, extraction, beneficiation, and

separation technologies with the potential for production, growth, and scalability. Ucore’s

vision and plan is to become a leading advanced technology company, providing best-in-

class metal separation products and services to the mining and mineral extraction

industry.

Through strategic partnerships, this plan includes disrupting the People’s Republic of

China’s control of the North American REE supply chain through the near -term

development of a heavy and light rare -earth processing facility in the US State of

Louisiana, subsequent SMCs in Canada and Alaska and the longer-term development of

Ucore’s 100% controlled Bokan -Dotson Ridge Rare Heavy REE Project on Prince of

Wales Island in Southeast Alaska, USA.

Ucore is listed on the TSXV under the trading symbol “UCU” and in the United States on

the OTC Markets’ OTCQX® Best Market under the ticker symbol “UURAF.”

Forward-Looking Statements

This press release includes certain statements that may be deemed “forward -looking

statements.” All statements in this release (other than statements of historical facts) that

address future business development, technological development and/or acquisitio n

activities (including any related required financings), timelines, events, or developments

that the Company is pursuing are forward -looking statements. Although the Company

believes the expectations expressed in such forward -looking statements are based on

reasonable assumptions, such statements are not guarantees of future performance or

results, and actual results or developments may differ materially from those in forward -

looking statements.

Regarding the disclosure in the press release above about the DOD project and the

expected successful progress of the project and the resulting milestone payments from

the DoD, the Company has assumed that the project (including each of its milestones)

will be completed in a satisfactory manner and in a reasonable period of time within

approximately the next two years. For additional risks and uncertainties regarding the

Company, the Commercialization and Demonstration Facility (“ CDF”), the Demo Plant

and the project (generally), see the risk disclosure in the Company’s MD&A for Q1 2025

(filed on SEDAR on May 9, 2025) (www. sedarplus.ca) as well as the risks described

below.

Regarding the disclosure above in the “About Ucore Rare Metals Inc.” section, the

Company has assumed that it will be able to procure or retain additional partners and/or

suppliers, in addition to Innovation Metals Corp. (“IMC”), as suppliers for Ucore’s

developing and future Strategic Metals Complexes (“SMCs”). Ucore has also assumed

that sufficient external funding will be found to complete the demonstration schedule and

also later prepare a new National Instrument 43 -101 (“NI 43 -101”) technical report th at

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 prevailing 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 commercial-

scale applications; Ucore not being able to procure additional key partners or suppliers

for the SMCs; Ucore not being able to raise sufficient funds to fund the specific design

and construction of the SMCs and/or the continued development of RapidSX™; adverse

capital-market conditions; unexpected due -diligence findings; the e mergence 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 Louisiana or

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

Authority (“AIDEA”) regarding the development of Bokan; the availability and procurement
