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 # # # About Ucore Rare Metals Inc.
