Ucore and Vulcan Elements Join Forces to Build DomesƟc Rare

Earth Magnet Supply Chain for Defense and Commercial

ApplicaƟons

Ucore highlights:

 Ucore and Vulcan Elements executed a Memorandum of Understanding to build a domes Ɵc,

secure rare earth magnet supply chain for defense and commercial applicaƟons.

 Ucore will provide iniƟal NdPr and Dy oxide samples to Vulcan this year, leading to a long-term

commercial supply agreement beginning in 2027.

 Together, Ucore and Vulcan Elements are onshoring an integrated rare earth magnet supply

chain. Ucore’s Louisiana Strategic Metals Complex will directly feed Vulcan’s North Carolina

manufacturing faciliƟes.

 Vulcan announced a $1.4 billion partnership with the United States Government to build the

largest rare earth magnet factory in the world outside of China, with 10,000 metric tonnes of

magnet manufacturing capacity.

Halifax, Nova ScoƟa - March 24, 2026 - Ucore Rare Metals Inc. (TSXV: UCU | OTCQX: UURAF) ("Ucore"

or the "Company") is pleased to announce the execuƟon of a Memorandum of Understanding dated

March 16, 2026 with Vulcan Elements Inc. (" Vulcan") to collaborate on the development of a

domesƟc rare earth magnet supply chain for defense and commercial applica Ɵons. Under the

agreement, the parƟes intend to finalize a full commercial supply partnership whereby Ucore would

supply Vulcan with NdPr oxide and Dy oxides at commercial scale beginning in 2027.

The collaboraƟon aligns Ucore’s demonstrated separaƟon plaƞorm at its Commercial DemonstraƟon

Facility ("CDF") in Kingston, Ontario, and its planned Louisiana Strategic Metals Complex ("SMC") in

Alexandria, Louisiana, with a leading American magnet manufacturer. Vulcan currently operates a

commercial magnet manufacturing facility in Durham, North Carolina, and is expanding to a 10,000

tonne magnet manufacturing facility in Benson, North Carolina. The facility is enabled by a $1.4 billion

partnership with the United States Government, including the Department of War and the

Department of Commerce. In May 2025, Ucore announced an $18.4 million Award by the Department

of War to develop its rare earth processing capabiliƟes in Louisiana.

Ucore intends to make a porƟon of its planned Louisiana SMC capacity available to Vulcan beginning

in 2027. The collaboraƟon would create a direct commercial bridge from Ucore’s demonstraƟon-scale

separaƟon work in Kingston to commercial-scale produc Ɵon in Louisiana, while suppor Ɵng Vulcan’s

manufacturing in North Carolina.

Pat Ryan, P.Eng., Chairman & Chief ExecuƟve Officer of Ucore, stated:

"Vulcan is building exactly the kind of downstream magnet plaƞorm that the United States

needs, and this partnership creates a winning commercial partnership that aligns Ucore’s

separaƟon capability with an industry-leading U.S. manufacturer. Our collaboraƟon will

anchor a resilient allied rare earth magnet supply chain in the United States."

John Maslin, Chief ExecuƟve Officer of Vulcan Elements, commented:

"Since its inception, Vulcan Elements’ mission has been to build a domestic rare earth

magnet supply chain that can propel America into the 21st century and enable the next

era of innovation and national security. Vulcan’s partnership with Ucore is a milestone

for both companies, and for the United States of America. Together, we’re rebuilding a

core industry that is criƟcal for economic growth and naƟonal security."

This year, Ucore and Vulcan intend to advance iniƟal producƟon, tesƟng protocols, purity targets,

acceptance criteria, and other technical specifica Ɵons in support of Vulcan’s magnet manufacturing

capability—leading to a longer-term commercial supply agreement.

of the SMCs and/or the con Ɵnued development of RapidSX ™; adverse capital- market condi Ɵons;

unexpected due-diligence findings; the emergence of alternaƟve superior metallurgy and metal -

separaƟon technologies; the inability of Ucore and/or IMC to retain its key staff members; a change

in the legisla Ɵon in Louisiana or Alaska and/or in the support expressed by the Alaska Industrial
