Halifax, Nova Scotia--(Newsfile Corp. - September 12, 2024) - Ucore Rare Metals Inc. (TSXV: UCU) (OTCQX: UURAF) ("Ucore" or the "Company") is pleased to provide an update on its latest advancements associated with the commercialization of its RapidSX^™ rare earth separation technology. In addition to demonstrating its patent-pending RapidSX^™ technology platform at the Commercialization and Demonstration Facility ("CDF") in Kingston, Ontario, for the separation of heavy and light rare earth elements ("REE"), the Company is trialing a number of ancillary systems to demonstrate the entire commercial flowsheet. These systems will ultimately be incorporated into Ucore's first commercial REE separation and rare earth oxide ("REO") production facility in Alexandria, Louisiana - the Louisiana Strategic Metals Complex ("SMC").

In parallel with a dedicated technical team, the CDF operates seven days per week, serving multiple purposes, requiring dedicated shift and activity schedules, namely:

• the processing of mixed rare earth oxide ("MREO") and carbonate ("MREC") feedstocks over thousands of runtime hours to further the Company's two government demonstration projects;

• to develop and demonstrate an array of ancillary processing systems with the deployment of the RapidSX™ technology platform in a rigorous production environment; and

• conduct product qualification work to meet prospective Western world partners' commercial interests and associated specifications.

RapidSX™ Operations

The Company schedules its 52-stage RapidSX™ Demonstration Plant ("Demo Plant") to operate 120 hours per week processing tonnes of feedstock in a simulated commercial environment. The completely automated system incorporates approximately 600 feedback sensors, which include monitoring acidity levels (pH), aqueous and organic interface levels, tank levels, and system pressures and flow rates, all of which are controlled by multiple programmable logic controllers ("PLCs") and a single operator at a central control station.

Since the Demo Plant was commissioned in late 2023, through a dedicated program of continuous improvement, the Ucore team has developed significant enhancements to the mechanical and control systems that deliver and remove the organic and aqueous solutions to each RapidSX™ stage. This is an essential component of the final "copy and paste" knowledge transfer process from the CDF to the SMC to ensure a robust and proven technology platform delivering best-in-class competitive processing versus that of the People's Republic of China.

Full Scope Operations

The purpose of the CDF is the demonstration of the entire rare earth refining flowsheet, which extends well beyond the separation of REEs utilizing the RapidSX™ system. The Company has been engaged in the development and demonstration of the associated operations, including:

• design and testing of an optimized Cerium depletion process;

• direct leaching of heavy MREO and light MREC, eliminating the pre-leaching calcining step traditionally required in the processing of MRECs;

• development of a dedicated yttrium removal process;

• design and installation of a distillation system for the concentration of produced rare earth chlorides and the recovery and recycling of hydrochloric acid;

• design and installation of a neutralization system to recycle and manage the generated rare earth chloride solutions; and

• development of a batch-level process for light and heavy rare earth oxide production.

End User Qualifications

Since the commencement of Kingston operations, Ucore has had numerous confidential requests for REO products produced to specifications from Western world end users. The CDF produces heavy and light rare earth chlorides from various feedstocks, including monazite, bastnaesite, ionic clays, and xenotime sources. This has been complemented by the development of a dedicated batch-level process area within the CDF for the production of kilogram quantities of rare earth oxides from the generated rare earth chlorides. This is the final processing step of the planned commercial REO production facility.

"It is an exceptionally exciting time for the Company," stated Mike Schrider, P.E., Vice President and Chief Operating Officer of Ucore. "The innovative work being completed at our Commercial Demonstration Facility strongly positions us as a first mover in the Western commercial heavy rare earth processing space as we continue to execute our plan for production in Louisiana.

"The Company is making daily advancements in our integrated knowledge of applying the chemistry of solvent extraction with our computerized column technology platform to the intricate separations involved with heavy rare earth elements. Our flowsheet development and demonstration work in Kingston are essential risk mitigation steps to help us achieve our Louisiana SMC commercial objectives."

The Company has hosted numerous visitors at the CDF over the past several months, including both potential feedstock and offtake partners, as well as supply chain alignment discussions with a variety of industry participants.
