F4 Announces Closing of $1.4 Million Private Placement

Kelowna, British Columbia--(Newsfile Corp. - June 19, 2025) - F4 Uranium Corp. (TSXV: FFU) (the "Company" or "F4") is pleased to announce that it has closed its previously announced non-brokered private placement consisting of 14,000,000 common shares of the Company (the "FT Shares") that qualify as "flow-through shares" for the purposes of the Income Tax Act(Canada) (the "Tax Act") at a price of $0.10 per FT Share for gross proceeds of $1,400,000 (the "Private Placement").

The Company intends to use the proceeds from the Private Placement to incur "Canadian exploration expenses" that qualify as "flow-through critical mineral mining expenditures" as such terms are defined in the Tax Act, and to incur "eligible flow-through mining expenditures" pursuant to The Mineral Exploration Tax Credit Regulations, 2014 (Saskatchewan) (collectively, the "Qualifying Expenditures") related to the Company's exploration program on five of its mineral properties located in the Athabasca Basin region of Saskatchewan (see June 4, 2025 news release). The Company intends to incur the Qualifying Expenditures on or before December 31, 2026, and renounce such Qualifying Expenditures in favour of the subscribers of the FT Shares effective December 31, 2025.

Red Cloud Securities Inc. ("Red Cloud"), among others (collectively, the "Finders") acted as finders for the Company in respect of the Private Placement. As compensation for their services, the Company paid to the Finders cash compensation equal to $69,360 and issued to Red Cloud 693,600 non-transferable finder warrants (the "Finder Warrants"). Each Finder Warrant entitles Red Cloud to acquire one common share of the Company (each, a "Common Share") at price of $0.10 per Common Share at any time until June 19, 2027.

All securities issued pursuant to the Private Placement are subject to a hold period of four months and one day expiring on October 20, 2025.

Certain insiders of the Company have acquired a total of 2,000,000 FT Shares under the Private Placement. Such participation is considered to be "related party transactions" within the meaning of TSX Venture Exchange ("TSX-V") Policy 5.9 (the "Policy") and Multilateral Instrument 61-101-Protection of Minority Security Holders in Special Transactions ("MI 61-101") adopted in the Policy. The Company is relying on the exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a) of MI 61-101 in respect of related party participation in the Private Placement as neither the fair market value (as determined under MI 61-101) of the subject matter of, nor the fair market value of the consideration for, the transaction, insofar as it involves interested parties, is expected to exceed 25% of the Company's market capitalization (as determined under MI 61-101). The Company did not file a material change report 21 days prior to closing of the Private Placement as the insider participation had not been confirmed at that time.

In addition, the Company announces that pursuant to the terms of a Financial Advisory Agreement between the Company and Haywood Securities Inc. ("Haywood"), as amended, the Company has agreed to issue to Haywood 666,667 Common Shares at a deemed price of $0.15 per Common Share (the "Success Fee"), plus applicable taxes payable in cash. The Success Fee is being paid to Haywood as compensation for acting as financial advisor to the Company in connection with the Company's "spin-out" transaction with F3 Uranium Corp. pursuant to a statutory plan of arrangement under Section 192 of the Canada Business Corporations Act. The payment of the Success Fee remains subject to the approval of the TSX-V, and the Common Shares comprising the Success Fee shall be subject to a hold period of four months and one day in accordance with the policies of the TSX-V.

This news release does not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of any of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful, including any of the securities in the United States of America. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the "1933 Act") or any state securities laws and may not be offered or sold within the United States or to, or for account or benefit of, U.S. Persons (as defined in Regulation S under the 1933 Act) unless registered under the 1933 Act and applicable state securities laws, or an exemption from such registration requirements is available.
