Ucore Rare Metals Inc. (TSXV: UCU) (OTCQX: UURAF) ("Ucore" or the "Company") is very pleased to announce that the Company's wholly owned subsidiary, Innovation Metals Corp. ("IMC" or the "company"), has successfully completed initial extraction-rate testing of its proprietary RapidSX™ separation technology and to provide an update on the company's RapidSX commercialization demonstration program and related timelines. Being a key technical milestone in the commercialization of RapidSX, the extraction-rate testing quantitatively confirmed the ability of the technology to rapidly extract rare-earth elements ("REEs") from an initial REE feedstock using a standard extractant, at rates at least ten times faster than conventional solvent extraction ("SX") technology.

Highlights

1. Successful initial extraction-rate testing demonstrated and re-confirmed that the RapidSX technology is highly effective at extracting REEs from solutions, within a range of flow rates;
2. RapidSX column design for commercial deployment is now in the finalization/optimization stage; and
3. IMC continues to advance the commercialization of the RapidSX technology via proprietary commercial hardware and software capabilities. This innovative, dual-channel approach will underpin the successful commercialization of RapidSX for REE separation, while also advancing non-REE RapidSX applications.

"The IMC team continues to make great strides in the RapidSX technology commercial deployment effort," commented Pat Ryan, P.Eng., Ucore Chairman and CEO. "This latest round of extraction-rate testing foreshadows the expected results as we embark on an Independent Evaluation of the RapidSX technology at the Kingston facility which will take place over the summer months of 2021. This Independent Evaluation will be conducted by the scientific team at Kingston Process Metallurgy ("KPM") under the supervision and direction of an independent third party who will report on the findings."

RapidSX Extraction-Rate Testing

The rate of extraction is an important contributor to the final design of the individual columns that will be used in RapidSX-based SX circuits, influencing their overall size when deploying the technology for particular applications. The recent testing looked at the effects of flow rate and residence time on the rate of extraction from a mixed REE solution.

The initial quantitative test results using a standard, commercial extractant for REEs indicate that the rate of mass transfer during operation of the RapidSX columns is at least one order-of-magnitude higher than that which occurs with the use of mixer-settler units for conventional SX extraction of REEs from solutions, i.e., at least ten times faster.

IMC Chairman, CEO and Co-founder, Dr. Gareth Hatch, stated, "The results of the initial extraction-rate testing for the current RapidSX columns are highly encouraging. Additional extraction-rate testing to validate and optimize platform parameters will be undertaken in the coming weeks, as IMC finalizes the design of the physical RapidSX hardware for deployment in IMC's forthcoming RapidSX Demonstration Plant. Additional extraction-rate testing will also be utilized to look at the influence of alternative extractants, currently being evaluated via equilibrium isotherm work."

Finalization of RapidSX Column Design

In addition to the initial extraction-rate testing, IMC has been working to finalize the individual physical RapidSX column assembly design so that it will be suitable for commercial deployment. Computational fluid dynamics ("CFD") software has been used to model fluid flows to subsequently fine-tune the design of certain components that will be utilized in the physical column assemblies.

Final column designs for the RapidSX Demonstration Plant ("Demo Plant") are in the process of completion, and will be tested in a demo-scale module ahead of construction of the Demo Plant, to empirically confirm effectiveness, at IMC's RapidSX Commercialization Development Facility ("CDF") in Kingston, Ontario, Canada.

Commercialization of the RapidSX Technology

IMC's ongoing commercialization work for the processing of REE feedstocks using RapidSX has now converged to simultaneous commercial hardware and software development. Together, these two initiatives will underpin the deployment of the RapidSX technology at commercial scale.

RapidSX Commercial Hardware Platform Development

The hardware platform development focuses on all of the physical hardware that is required for utilization of the RapidSX technology. This includes the proprietary RapidSX columns, as well as the supporting instrumentation, controls, sensors, piping, pumps, and all other physical equipment required.

Wherever possible, IMC will utilize the same hardware components in the forthcoming Demo Plant, as those that will be deployed at commercial scale. This will allow the Company to operate a Demo Plant at the CDF - scheduled for construction and commissioning later this year - that will very much look and feel like a full-scale, commercial facility.

RapidSX Commercial Software Tool Development

In parallel to the RapidSX hardware development work, IMC's technical team is focused on the development of a proprietary RapidSX software tool to instruct and control the hardware platform during operation. At the heart of this software tool will be the mathematical model previously disclosed by IMC, which will utilize the empirical REE extraction and separation data generated by IMC over the past several months, from a number of REE feedstocks. Once complete, the integrated software tool will work in concert with the hardware platform to provide near real-time adjustments to variations in feed and flow parameters, as appropriate. The same tool will also be responsible for determining the optimal metallurgical flowsheet for specific mixed REE concentrate feedstocks (input) and the specific REE oxides to be produced (output). This dictates the configuration and staging of the RapidSX hardware and controls the hardware platform. The software tool will allow IMC to analyze numerous flowsheet scenarios to achieve cost optimization, without the need for onerous and time-consuming "wet chemistry" development work.

RapidSX Commercialization Timeline

As announced on January 29, 2021, and May 4, 2021, the commissioning of IMC's RapidSX Demo Plant is scheduled to commence in late Q3 / early Q4 2021, with a comprehensive, independent techno-economic study and the design of a commercial-scale REE separation facility, both planned for completion by Q1 2022. With the anticipated ability to demonstrate the effectiveness of the Demo Plant on currently available REE feedstocks, IMC expects the RapidSX technology to be ready for commercial adoption and implementation in less than 12 months (in Q2/Q3 2022), via revenue-producing licensing agreements with strategically selected IMC customers.

About Innovation Metals Corp.

IMC has developed the proprietary RapidSX™ process, for the low-cost separation and purification of rare-earth elements, Ni, Co, Li and other technology metals, via an accelerated form of solvent extraction. IMC is commercializing this approach for a number of metals, to help enable mining and metal-recycling companies to compete in today's global marketplace.

About the RapidSX™ Technology

IMC developed the RapidSX separation technology with the assistance of US$1.8 million in funding from the United States Department of Defense ("US DoD"), resulting in the production of commercial-grade, separated REOs at the pilot scale. RapidSX combines the time-proven chemistry of conventional 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 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.
