Ucore Demonstrates the Flexibility of RapidSX™ by
Producing 99.5% NdPr from Multiple Sources
Ucore announces:
• It has produced 99. 5% NdPr sample material from two different feedstock sources (ionic
clay and bastnaesite) at its Commercialization and Demonstration Facility (“CDF”) in
Kingston, Ontario, for ongoing and planned customer qualifications
• NdPr is a fundamental product of most rare earth processing faciliti es, and on a scale of
tonnes, Ucore has now demonstrated the ability to create 99.5% material from multiple
sources with widely varying rare earth element compositions
Halifax, Nova Scotia – August 20 , 2026 - Ucore Rare Metals Inc. (TSXV: UCU | OTCQX: UURAF)
(“Ucore” or the “Company”) is pleased to announce that it has produced 99.5% NdPr from a second
feedstock source at its Commercialization and Demonstration Facility (“CDF”) in Kingston, Ontario, for
ongoing and planned customer qualifications:
• The first batch of 99.5% NdPr material was processed from approximately two tonnes of
Vietnamese mixed rare earth oxide (“MREO”) derived from ionic clay source material and sent
to Western NdFeB magnet makers for product testing in Q2-2026;
• The second batch of 99.5% NdPr material was produced in early August 2026 and was
processed from approximately five tonnes of mixed rare earth carbonate (“ MREC”) derived
from North American bastnaesite source material.
Ucore continues to demonstrate the versatility and adaptiveness of its RapidSX™ technology platform
in the simulated commercial environment of its Kingston CDF. NdPr is a fundamental product of most
rare earth processing facilities. It will be a featured product along with samarium (Sm), gadolinium
(Gd), terbium (Tb), dysprosium (Dy) , and eventually yttrium (Y) within the developing Louisiana
Strategic Metals complex (“ SMC”). On a tonnes-of-processing scale, the Company has now
demonstrated the production of 99.5% NdPr material from multiple sources with widely varying rare
earth element (“REE”) compositions.
The 7,400+ hours of simulated commercial runtime and corresponding commercial scale-up work at
the CDF have demonstrated the potential of the computerized and patent -pending RapidSX™
technology platform for full-scale REE processing. The chemistry of RapidSXTM is the same as that of
conventional solvent extraction. As a result, as demonstrated in over 16,000 comparative test results,
RapidSXTM typically yields recovery rates and target product purities equal to, or better than
conventional solvent extraction; the only difference being faster processing throughput and a smaller
equipment footprint for the same processing capacity. Together, these attributes have the potential
to create multiple opportunities for commercial savings and efficiencies, which Ucore is incorporating
into its developing Louisiana SMC.

“Ucore is executing a very deliberate plan for the development of its first RapidSX™ production
‘Machine A’ at the Louisiana SMC ,” stated Mike Schrider, P .E., Ucore’s Vice President and
Chief Operating Officer. “The work done at the CDF directly supports and validates the SMC
engineering program while simultaneously demonstrating the effectiveness of the technology
platform. Our work in Kingston will continue to serve as a co -commissioning, technology
development and training center to support and de-risk our commercial endeavors.”

Forward-Looking Statements
This press release contains “forward-looking information” and “forward-looking statements” (collectively,
“forward-looking statements”) within the meaning of applicable Canadian securities laws. All statements
in this release (other than statements of historical facts) that address future business development,
technological development and/or acquisition activities (including any related required financings),
timelines, events, products to be produced at the Louisiana SMC , or developments that the Company i s
pursuing are forward-looking statements. Although the Company believes the expectations expressed in
such forward -looking statements are based on reasonable assumptions, such statements are not
guarantees of future performance or results, and actual results or developments may differ materially from
those in forward-looking statements.
Forward-looking statements in this release include, without limitation, statements regarding the
development or execution of definitive supply , offtake agreements or other commercial agreements; the
acceptability of rare earth oxide samples to magnet makers and other end users of product; the ability to
provide high-purity materials or on-spec product to customers on an on-going basis; and the acceptability
of the referenced samples to potential customers.
For additional risks and uncertainties regarding the Company, its business activities, its ability to qualify
for and receive any additional funding from any U.S. or Canadian government, the CDF and the
aforementioned projects (generally), see the risk disclosure in the Company’s MD&A for Q1-2026 (filed on
SEDAR+ on May 29, 2026) (www.sedarplus.ca) as well as the risks described below.
Regarding the disclosure above in the “About Ucore Rare Metals Inc.” section, the Company has assumed
that it will be able to procure or retain additional partners and/or suppliers as suppliers for Ucore’s
expected future SMCs. Ucore has also assumed that sufficient external funding will be found to continue
and complete the ongoing research and development work required at the CDF and also later prepare a
National Instrument 43-101 technical report that demonstrates that Bokan is feasible and economically
viable for the production of both REE and co -product metals and the then prevailing market prices based
upon assumed customer offtake agreements. Ucore has also assumed that sufficient external funding will
be secured to continue the development of the sp ecific engineering plans for the SMCs and their
construction and eventual commissioning and operations.
Forward-looking statements are based on a number of material assumptions, including, without limitation:
the successful completion and accuracy of baseline, front-end-engineering design and detailed engineering
studies; the ability to complete further engineering, procurement, and construction activities as currently
contemplated; the availability, cost, and timely delivery of equipment, materials, utilities, labour and
construction services; the Company’s ability to secure sufficient financing on acceptable terms; the receipt
and timing of all required permits and approvals; the successful scale -up and commercial deployment of
RapidSX™ technology from demonstration to commercial operation; the availability of qualified feedstock
from third-party suppliers; successful customer qualification and offtake discussions; continued support
from governmental partners; and general economic, marke t, and industry conditions, including
assumptions regarding rare earth oxide prices, which are subject to significant volatility..
Although the Company believes that the assumptions underlying the forward -looking information are
reasonable, there can be no assurance that such assumptions will prove to be accurate or that the
anticipated results, performance, or achievements will be re alized. Actual results may differ materially
from those expressed or implied by the forward-looking information.
Factors that could cause actual results to differ materially include, without limitation: risks associated with
the development, scale -up, and commercialization of new or unproven technologies; the risk that
RapidSX™ may not perform at commercial scale as expected; engineering design changes; inaccuracies in
capital or operating cost estimates; cost escalation due to inflation, supply chain disruption, or market
conditions; delays or failures in procurement, constructi on, or commissioning; the inability to obtain or
maintain required permits, approvals, or regulatory authorizations; challenges in securing adequate
financing; adverse capital market conditions; variability in feedstock supply, quality, or pricing; failure to
secure or maintain commercial relationships, customer qualification, or offtake arrangements; fluctuations
and uncertainty in rare earth oxide prices and demand; the risk that indicative or quoted market prices,
including for ex -China markets, may not be realized; operational risks once in production, including
equipment failures or lower -than-expected recoveries; geopolitical risk; changes in applicable laws or
regulations; environmental or permitting challenges; loss of key personnel; and general economic,
