Ucore Announces Strategic Alliance with

Vacuumschmelze and eVAC Magnetics LLC for the

Supply of Rare Earth Oxides

Ucore announces:

 eVAC Magnetics has completed construction of a rare earth permanent

magnet manufacturing facility in Sumter County, South Carolina with

support from the US DoW and a $111.9 million Qualifying Advanced Energy

Project Tax Credit

 VAC also produces magnets at its facilities in Europe requiring rare earth

oxides for product lines including neodymium-iron-boron (NdFeB) and

Samarium-Cobalt (SmCo) permanent magnets.

 The Memorandum of Understanding (MOU) provides a means for eVAC and

VAC to align with Ucore for the supply of high-purity rare earth oxides which

will be coordinated with Ucore’s staged growth refining plans in Louisiana,

USA and Ontario, Canada.

Halifax, Nova Scotia — (November 3, 2025) — Ucore Rare Metals Inc. (TSXV: UCU)

(OTCQX: UURAF) (“Ucore” or the “Company”) is pleased to announce the signing of a

Memorandum of Understanding (“MOU”) with Vacuumschmelze GmbH & Co. KG (“VAC”)

and eVAC Magnetics LLC (“eVAC”) to develop a collaborative supply agreement for high-

purity rare earth oxides (“REOs”).

VAC is part of VACUUMSCHMELZE ( "VAC Group”) with operations beginning Fall of

2025 in Sumter County, South Carolina, under eVAC Magnetics LLC, and has received

strong federal and state support including a Defense Production Act Title III grant from

the Department of War and a $111.9 million Qualified Advanced Energy Project Tax

Credit.

The eVAC facility and VAC’s decades of experience in Europe with rare earth magnet

technology and process intellectual property is a critical piece to securing stable Western

World supply. NdFeB permanent magnet solutions are critical to automotive, industrial

automation and renewable energy applications, while Samarium-Cobalt magnets are

essential to defense systems including advanced radar, sonar and guidance systems. To

ensure a sustainable and long-term supply of rare-earth oxides, Ucore’s RapidSX ™

refining plans advancing in Alexandria Louisiana and Kingston, Ontario become a vital

strategic input for unified market growth plans.

Under the contemplated framework, Ucore will supply VAC and eVAC with separated rare

earth oxides—including neodymium (Nd), praseodymium (Pr), terbium (Tb), dysprosium

(Dy), samarium (Sm), and gadolinium (Gd)—produced at Ucore’s planned Louisiana

Strategic Metals Complex (“Louisiana SMC”) in Alexandria, Louisiana, and its

Commercial Demonstration Facility (“CDF”) in Kingston, Ontario.

Pat Ryan, P.Eng., Ucore Chairman & CEO, stated:

“It's known in critical industries of defense, EV automotive and renewable energy that

VAC and eVAC represent an extensive supply network with decades of experience for

rare earth permanent magnet production and magnetic solutions. As such we are

extremely pleased with our strategic alignment which will allow Ucore to provide critical

rare earth oxides produced using Ucore's RapidSX ™ refining technology for VAC and

eVAC's growing global markets. We anticipate that joining forces to provide a complete

supply chain solution in particular for Europe and North America, will support lasting

growth for years to come."

company focused on the development of rare earth element projects and refining

technologies. This collaboration strengthens VAC’s and eVAC’s strategic position in the

global rare earth supply chain and ensures long-term access to critical raw materials for

our permanent magnet products. Partnering with Ucore reflects our commitment to

sustainable innovation and securing supply resilience."

Next Steps

The parties will define the structure and commercial terms for a definitive long-term

agreement within nine months, supported by regular progress reviews..
