UCORE EXTENDS TERM OF OUTSTANDING CONVERTIBLE DEBENTURES AND PROVIDES CORPORATE UPDATE

Ucore Rare Metals Inc. intends to extend the term of certain outstanding convertible debentures which currently have a maturity date of May 31, 2023.

The Convertible Debentures were originally issued in May of 2020, with a three-year term. On May 21 and 29, 2020, the Company issued 1,280 and 1,520 Convertible Debentures respectively, with a face value of $1,000 each for total gross proceeds of $2.8 million. These unsecured Convertible Debentures bear interest at a rate of 7.5% payable semi-annually and mature on May 31, 2023. Pursuant to the terms of the Convertible Debentures, the Company has the option to extend the maturity date by one year in exchange for the payment of an extension fee equal to 6-months interest.

The Company intends to exercise its right to extend the maturity date of the remaining outstanding Convertible Debentures by one year, with a resulting maturity date of May 31, 2024 (the "Maturity Date"), and to pay the extension fee of $47,063.

At any time during the term of the Convertible Debentures, a holder may elect to convert the outstanding net principal amount, or any portion thereof, into units ("Units") at a conversion price of $1.20 per Unit (the "Conversion Price"). Each Unit shall consist of one common share of the Company (a "Common Share") and one-half of a warrant ("Warrant"), with each whole Warrant entitling the holder to acquire a Common Share at an exercise price of $1.80 for a period ending on the Maturity Date.

As of May 3, 2023, a total of 1,545 Convertible Debentures have been previously converted into Units, resulting in the issue of 1,287,483 Common Shares and 643,746 Warrants. As a result, a total of 1,255 Convertible Debentures remain outstanding as at today's date.

The Company further reports that it intends to extend the term of the previously issued Warrants by one year, to match the revised term of the Convertible Debentures. A total of 643,746 Warrants will now have a term ending on May 31, 2024, the Maturity Date. The extension of the term of the Warrants will be conditional upon the approval of the TSX Venture Exchange (the "TSXV").

Additionally, the Company is pleased to report that it has entered into a new Secured Credit Facility Agreement with Orca Holdings, LLC in the amount of up to USD$1 million (the "2023 Facility"). Proceeds from the 2023 Facility will primarily be used to continue commission trials at the Company's RapidSXTM Rare Earth Element ("REE") Commercial Demonstration Plant located in Kingston, Ontario. Drawdowns on the 2023 Facility will be available in multiples of USD$100,000 and will carry interest at a rate of 10% per annum. All amounts owing under the 2023 Facility will be repayable by December 31, 2023. An administrative loan origination fee equal to 1.5% of the available 2023 Facility will be paid at maturity. A total of 1 million bonus warrants will be issued as consideration for the granting of the 2023 Facility. The warrants will contain a condition precedent to their exercise such that no warrant shall be exercisable if such exercise would cause the lender's ownership of the Company, as calculated on a partially diluted basis, to exceed 19.99%. The warrants will have an exercise price of $1.20 and a term of 12 months from the date of issue. Each warrant, and underlying share, shall be subject to a restricted period such that the holder must not trade the security before the date that is four months and one day after the date of issue. The issuance of the warrants will be conditional upon the approval of the TSX Venture Exchange (the "TSXV").

Orca is wholly owned by Mr. Randy Johnson, a member of Ucore's Board of Directors. The transaction is considered a related party transaction within the meaning of Multilateral Instrument 61-01 Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The transaction is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101 as neither the fair market value of the subject matter of the transaction, nor the consideration paid, exceeds 25% of the Company's market capitalization. No new insiders and no control persons were created in connection with the closing of the transaction. The transaction was reviewed and unanimously approved by the Company's Board of Directors. No special committee was created to negotiate, review and approve the 2023 Facility agreement; rather, the agreement was negotiated by the Company with Mr. Johnson declaring his conflict and abstaining from the Board of Directors' deliberations. No cash consideration was paid pursuant to the extension of the 2023 Facility (other than the loan origination fee, which is associated with the administrative aspects of creating the 2023 Facility and making the funds available), and no commissions or similar fees were paid to any person. This news release and the related material change report are being issued and filed on SEDAR less than 21 days before the date of the 2023 Facility agreement and the expected drawdown of the initial tranche from the 2023 Facility since the Company was considering and reviewing financing alternatives and the Company eventually selected the least dilutive and most current-shareholder-friendly financing transaction from the alternatives available, which was the 2023 Facility, the terms of which were not settled and confirmed by Orca until May 9, 2023.

Further, the Company is pleased to report that it has engaged InvestorBrandNetwork ("IBN"), a multifaceted financial news and publishing company, to provide corporate communications expertise and related services. The Company expects that IBN will leverage its investor-based distribution network of 5,000+ key syndication outlets, various newsletters and other outreach tools to generate awareness of the Company. The Company has engaged IBN until January 2024 at a cost of $19,000 per quarter. The Company has additionally engaged Goldinvest Consulting GmbH ("Goldinvest") for a period ending on June 30, 2023 at a total cost of $16,000. Goldinvest will prepare corporate videos and assist with marketing activities in the German market. # # #
