Ucore's Rare Earth Separation Commercial Demonstration Plant On-Track for Q4-2022 Commissioning

• Ucore's rare earth separation commercial demonstration plant is designed to process:
  • Tens of tonnes of mixed rare earth concentrates on a per annum basis.
  • Many feedstock sources, including heavy and light rare earth element feedstocks planned for the full-scale Strategic Metals Complexes (SMC).
  • All RapidSX™ splits required to produce individual praseodymium, neodymium, terbium, and dysprosium.
• Planned commissioning in Q4-2022, followed by product qualification trials for prospective North American metal/alloy makers and original equipment manufacturers seeking diversified and sustainable metallic supply chains.
• The full-scale SMC engineering entity, Mech-Chem Associates, Inc., is now fully integrated into all demonstration plant activities.

Halifax, September 15, 2022 - Ucore Rare Metals Inc. (TSXV: UCU) (OTCQX: UURAF) ("Ucore" or the "Company") is pleased to provide an update on the Innovation Metals Corp.^[i] ("IMC") RapidSX™ rare earth element ("REE") separation technology platform and the Company's commercial Strategic Metals Complex ("SMC") technology deployment process (the "Program"). The work is taking place at the companies' laboratory partner's (Kingston Process Metallurgy Inc. ("KPM")) facility in Kingston, Ontario, Canada.

The Program was enhanced after Ucore received the independent evaluation of the RapidSX™ technology platform leading to the subsequent July 12, 2022, announcement of the nearly 3X increase in scope of the RapidSX™ REE demonstration-scale plant ("Demo Plant"). Since then, the Ucore, IMC, KPM, and Mech-Chem Associates, Inc.^[ii] ("Mech-Chem") commercialization team (the "Team") has made significant strides in the procurement and construction process for the Demo Plant.

The final engineered layout of the Demo Plant takes up nearly all of the 5,000 square foot Commercialization and Demonstration Facility ("CDF") at KPM. And the concept of building a plant within an existing building is the go-forward transition template for the engineering process that the Team will replicate to create the first full-scale SMC, once the brownfield site^[iii] selection process is finalized. This initial SMC is scheduled to produce 2,000 tonnes of total rare earth oxides ("TREOs") by the end of 2024 and 5,000 tonnes by 2026.

"The CDF Team, and the rest of the world, is facing extraordinary supply chain challenges regarding equipment and component availability," stated Mike Schrider, P.E., Ucore's VP and COO. "Despite this situation, we have managed to procure the initial feedstocks and virtually all of the required major equipment and components, and the Demo Plant remains on track for a late 2022 commencement of the commissioning process."

"This process will demonstrate the unprecedented North American separation of tonnes of both heavy and light rare earth elements. It will then continue with end-user qualification trials throughout 2023 for Western entities seeking diversified and sustainable metallic supply chains as Ucore transitions to full-scale commercial mode with the construction of our first SMC."

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 a wide variety of 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.

Ucore stands alone in its speed of executing the commercial deployment of one of the first modern technology platforms for separating HREEs and LREEs - as a replacement for CSX. Mech-Chem is now fully integrated into all CDF activities and is aligned to assist with 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 is rapidly positioning Ucore to meet the demanding schedule requirements for the development of the first SMC and REO production for the Company's emerging list of prospective downstream partners.

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 oxides 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.
