Ucore Receives a Crucial DPAS-Rated Long Lead Equipment Component at the

Louisiana SMC

Halifax, Nova Scotia – April 16, 2026 – Ucore Rare Metals Inc. (TSXV: UCU | OTCQX:

UURAF) (“Ucore” or the “Company”) is pleased to announce the arrival of a crucial piece of

long-lead-time equipment at its Louisiana Strategic Metals Complex (“ LA-SMC”) in

Alexandria, LA. The equipment was procured under the Company’s US$22.4 million modified

funding agreement with the US Army Contracting Command -Orlando and associated

Defense Priorities & Allocations System (“DPAS”) Rating. The equipment is a GMM Pfaudler

US Inc. 4,000 -gallon jacketed glass -lined reactor designed to leach a wide variety of

planned Western mixed rare earth oxides (“ MREO”) and mixed rare earth carbonates

(“MREC”) to be received at the LA-SMC.

Ucore presented its DPAS DO-B8 rating in a September 19, 2025, news release and noted

that a DPAS rating imposes legal obligations on equipment suppliers, requiring that fulfillment

of any LA -SMC order be given preferential treatment over unrated orders to meet national

defense and emergency preparedness requirements.

The offloading and placement of the Reactor within the LA-SMC was successfully coordinated

by Ucore’s selected LA-SMC construction management contractor, Ratcliff Construction of

Alexandria, LA. A section of the end wall was removed and replaced to facilitate the

placement of the reactor within the building.

“The arrival of this major piece of equipment is a significant milestone for the Ucore Team as

we stay laser-focused on establishing commercial rare earth processing in Louisiana,” stated

Mike Schrider, P.E., Ucore Vice President and Chief Operating Officer . “Ucore is

conducting a coordinated knowledge transfer of its RapidSX ™ technology platform and

ancillary processing systems from its Commercialization and Demonstration Facility [CDF] in

Kingston, Ontario, to the LA -SMC. This effort will continue throughout 2026, with the

installation of one RapidSX™ Machine scheduled for commissioning and product qualification

trials in H1-2027.”

Coordinated CDF to LA-SMC activities include:

• Anticipated LA-SMC feedstock testing and separation trials at the CDF

• Factory Acceptance Testing (“FAT”) of the RapidSX™ Commercial Scale Equipment

Platform at the CDF

• LA-SMC Engineering , Procurement, and Construction (“EPC”) personnel

familiarization, design, procurement, construction, and /or testing of the CDF

equipment and processes

• LA-SMC personnel training at the CDF
