Each Unit will consist of one common share in the capital of the Company (a "Common Share") and one-half of one Common Share purchase warrant (each whole Common Share purchase warrant, a "Warrant"). Each Warrant will entitle the holder thereof to purchase one Common Share (a "Warrant Share") at any time on or before the date which is 36 months following the Closing Date (as herein defined) at an exercise price of C$1.75.

Red Cloud Securities Inc., as lead agent and sole bookrunner, together with Raymond James Ltd. (collectively, the "Agents"), are acting as agents in connection with the Offering. The Company has granted the Agents an option (the "Agents' Option", and together with the Marketed Offering, the "Offering"), exercisable in whole or in part up to 48 hours prior to the closing of the Offering, to offer and sell up to an additional 1,250,000 Units at the Offering Price for additional gross proceeds of up to C$1.5 million. If the Agents' Option is exercised in full, the aggregate gross proceeds of the Offering to the Company will be C$15.5 million.

The Units to be issued under the Offering will be offered to purchasers pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106 – Prospectus Exemptions, as amended by Coordinated Blanket Order 45-935 – Exemptions from Certain Conditions of the Listed Issuer Financing Exemption, in all the provinces of Canada, except Québec. The Units and the securities underlying the Units will not be subject to resale restrictions pursuant to applicable Canadian securities laws.

The Agents will also be entitled to offer the Units for sale in the United States pursuant to available exemptions from the registration requirements of the United States Securities Act of 1933, as amended (the "U.S. Securities Act"), and in those other jurisdictions outside of Canada and the United States provided it is understood that no prospectus filing or comparable obligation arises in such other jurisdiction.

As previously disclosed, the net proceeds of the Offering are expected to be used for the following: (i) finalization of upstream mixed-rare-earth feedstock agreements and downstream customer offtake agreements for the Company's planned strategic metals complex ("SMC") in Louisiana, USA; (ii) completion of the Company's existing obligations pursuant to its agreements with the U.S. Department of Defense and Natural Resources Canada; (iii) commercial scale column confirmation testing; (iv) progressing engineering drawings and plans, which are currently ongoing, for the Company's planned SMC; and (v) general working capital requirements.

There is an amended and restated offering document relating to the Offering that can be accessed under the Company's profile at www.sedarplus.ca and on the Company's website at www.ucore.com. Prospective investors should read this amended offering document before making an investment decision.

It is anticipated that the Offering will close on or about June 19, 2025, and is subject to certain closing conditions including, but not limited to, the receipt of all necessary approvals, including the conditional approval of the TSX Venture Exchange (the "TSXV").

This press release shall not constitute an offer to sell or the solicitation of an offer to buy securities in the United States, nor shall there be any sale of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful. The securities being offered have not been, nor will they be, registered under the U.S. Securities Act or under any U.S. state securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the U.S. Securities Act, as amended, and applicable state securities laws.

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 acquisition 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 timing and completion of the Offering; the intended use of proceeds from the Offering; and the receipt of any regulatory approvals, including the conditional and 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 in the press release above, the Company has assumed, among other things, that it will receive the approvals of the TSXV in regard to the Offering and the issuance of the Units in connection therewith. If the TSXV objects or does not provide its approval for either of the transactions contemplated hereby, then the Company will have to negotiate revised terms with the applicable counterparties, and there is no assurance that the parties will reach an agreement that is acceptable to the Company.

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 Demonstration Plant (Kingston) activities and also later prepare a new National Instrument 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 construction of the SMCs and/or the continued development of RapidSX™; adverse capital-market conditions; unexpected due diligence 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.

Neither the TSXV nor its Regulation Services Provider (as that term is defined by the TSXV) accept responsibility for the adequacy or accuracy of this release.
