Forward-Looking Statements

This press release includes certain statements that may be deemed “forward-looking statements”.

All statements in this release (other than statements of historical facts) that address future

business development, technological development and/or acquisitio n activities (including any

related required financings), timelines, events, or developments that the Company is pursuing are

forward-looking statements, including without limitation statements with respect to the intended

use of proceeds from the Offering and the receipt of final approvals of the TSXV. 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.

Regarding the disclosure that is in the "About Ucore Rare Metals Inc." and “About RapidSX ™

Technology” sections above, the Company has assumed that it will be able to procure or retain

additional partners and/or suppliers, in addition to Innovation Metals Corp. (“ IMC”), as suppliers

for Ucore’s expected future SMCs. Ucore has also assumed that sufficient external funding will

be found to complete the SMC commissioning and Kingston Demonstration Plant activities and

also later prepare a new National Instrume nt 43-101 technical report that demonstrates that the

Bokan Mountain Rare Earth Element project (“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 specific engineering plans for the SMCs and

their construction. Factors that could cause actual results to differ materially from those in forward-

looking statements include, without limitation: IMC failing to protect its intellectual property rights

in RapidSX™; RapidSX™ failing to demonstrate commercial viability in large commercial -scale

applications; Ucore not being able to procure additional key partners or suppliers for the SMCs;

Ucore not being able to raise sufficient funds to fund the specific design and construct ion of the

SMCs and/or the continued development of RapidSX ™; adverse capital -market conditions;

unexpected duediligence findings; the emergence of alternative superior metallurgy and metal -

separation technologies; the inability of Ucore and/or IMC to retain its key staff members; a

change in the legislation in Louisiana or Alaska and/or in the support expressed by the Alaska

Industrial Development and Export Authority (AIDEA) regarding the development of Bokan; the

availability and procurement of any required interim and/or long -term financing that may be

required; and general economic, market or business conditions.
