Halifax, Nova Scotia--(Newsfile Corp. - November 16, 2022) - Ucore Rare Metals Inc. (TSXV: UCU) (OTCQX: UURAF) ("Ucore" or the "Company") is pleased to provide an update on its RapidSX™ rare earth element ("REE") separation technology platform and the Company's Louisiana Strategic Metals Complex ("SMC") technology deployment process (the "Program"). The work is taking place at the Company's RapidSX™ Commercialization and Demonstration Facility ("CDF") in Kingston, Ontario, which is operated by its laboratory partner Kingston Process Metallurgy Inc. ("KPM").

The Ucore, IMC, KPM, and Mech-Chem Associates, Inc.^[i] ("Mech-Chem") commercialization team (the "Team") continues to make significant strides in the procurement and construction process for the RapidSX™ REE demonstration-scale plant ("Demo Plant").

The final engineered layout of the Demo Plant takes up nearly all of the 5,000 square foot CDF. And the concept of building a plant within an existing building is the go-forward engineering process that the Team will replicate to create the first full-scale SMC within one of three designated Louisiana brownfield site^[ii] facilities once the selection process is finalized.

As Ucore announced on October 17, 2022, the Louisiana SMC is scheduled to initially produce 2,000 tonnes of total rare earth oxides ("TREOs") by the end of 2024, increasing to 5,000 tonnes by 2026. The Company is engaged in numerous discussions for the required development funding for its first SMC. The project is expected to be funded with C$15+ million from the State of Louisiana, prepurchase and supply offtake agreements, various debt financing programs, government grants, and other means.

Since acquiring IMC in May of 2020, Ucore's 2-1/2 year RapidSX™ development program has allowed the Company to position itself as a first-mover toward the commercial production of heavy and light REOs in North America. The assembled commercialization team is fully integrated into all CDF activities and is aligned to develop the full-scale SMC techno-economic assessment and engineering data transfer.

The efficiencies and environmental advantages resulting from the CDF demonstration processes are, and will continue to be, directly incorporated into the full-scale SMC engineering design packages. This integrated process rapidly positions Ucore to meet the demanding schedule requirements for developing the first SMC and corresponding REO production for the Company's emerging list of prospective downstream partners.

Ucore's REE separation Demo Plant is designed to:

• Have the ability to process tens of tonnes of mixed rare earth concentrates on a per annum basis:
  • from multiple feedstock sources, including the heavy REE ("HREE") and light REE ("LREE") feedstocks planned for the full-scale SMCs.
• Be capable of processing all RapidSX™ splits required to produce individual praseodymium, neodymium, terbium, and dysprosium.
• Have a parallel 51-stage conventional solvent extraction ("CSX") mixer/settler circuit that will match the RapidSX™ process' configuration and enable direct head-to-head comparison of the performance of RapidSX™ vs. CSX.

"The CDF team is diligently working towards the commencement of the commissioning process, scheduled for the week of December 19, 2022," stated Mike Schrider, P.E., Ucore's VP and COO. "We remain very fortunate that most of our procurement and installation activities have stayed on course and that we have been able to come up with workarounds for the few items requiring an alternative approach.

"As discussed in our September 2022 update, a North American rare earth separation plant capable of processing tonnes of different feedstock sources, including heavy and light rare earth elements, has never been accomplished in North America. Ucore intends to incorporate the characteristics and findings from the Demo Plant into a techno-economic assessment to feed directly into the full-scale design, engineering and cost estimate for the Louisiana SMC."

About RapidSX™ Technology

IMC developed the RapidSX™ separation technology platform with early-stage assistance from the United States Department of Defense ("US DoD"), later resulting in the production of commercial-grade, separated rare-earth elements at the pilot scale. RapidSX™ combines the time-proven chemistry of conventional solvent extraction ("SX") with a new column-based platform, which significantly reduces time to completion and plant footprint, as well as potentially lowering capital and operating costs. SX is the international rare-earth element ("REE") industry's standard commercial separation technology and is currently used by 100% of all REE producers worldwide for bulk commercial separation of both heavy and light REEs. Utilizing similar chemistry to conventional SX, RapidSX™ is not a "new" technology but represents a significant improvement on the well-established, well-understood, proven conventional SX separation technology preferred by REE producers.
