Kelowna, British Columbia--(Newsfile Corp. - May 30, 2024) - F3 Uranium Corp. (TSXV: FUU) (OTCQB: FUUFF)

("F3 Uranium" or the "Company") is pleased to announce the closing of its previously announced "bought deal" private

placement (the "Offering") for aggregate gross proceeds of C$10,074,414.59, which includes the full exercise of the

Underwriters' over-allotment option. Under the Offering, the Company sold 7,409,908 federal flow -through units of the

Company (the "FFT Units") at a price of C$0.5355 per FFT Unit and 10,447,235 Saskatchewan flow -through units of the

Company (the "SFT Units", and together with the FFT Units, the "FT Units") at a price of C$0.5845 per SFT Unit, for an

aggregate of 17,857,143 FT Units at a blended price of C$0.5642 per FT Unit on a "bought deal" basis.

Red Cloud Securities Inc. acted as lead underwriter and sole bookrunner on behalf of a syndicate of underwriters that

included Canaccord Genuity Corp., Haywood Securities Inc., SCP Resource Finance LP and Eight Capital (collectively, the

"Underwriters").

Each FT Unit consists of one common share of the Company (each, a "Common Share") issued as a "flow-through share"

within the meaning of the Income Tax Act (Canada) (each, a "FT Share") and one half of one Common Share purchase

warrant (each whole warrant, a "Warrant"). Each whole Warrant shall entitle the holder to purchase one Common Share at

a price of C$0.56 at any time on or before May 30, 2026.

A total of 8,928,571 FT Units under the Offering, representing gross proceeds of C$4,999,999.74, were offered by way of

the "listed issuer financing" exemption under Part 5A under National Instrument 45-106 - Prospectus Exemptions ("NI 45-

issuable pursuant to the sale of these FT Units are immediately freely tradeable under applicable Canadian securities

legislation if sold to purchasers resident in Canada. The remaining 8,928,572 FT Units sold under the Offering were offered

by way of the "accredited investor" and "minimum amount investment" exemptions under NI 45- 106 in the Selling

Jurisdictions. The Common Shares issuable from the sale of such FT Units are subject to a restricted period in Canada

ending on October 1, 2024.

In connection with the Offering, the Company paid to the Underwriters an aggregate cash commission of C$540,342.80,

equal to 5.5% of the gross proceeds raised in respect of the Offering (except for gross proceeds raised from the sale of FT

Units sold to purchasers on a president's list (the "President's List"), which were subject to a reduced 2.75% cash

commission). The Company also issued to the Underwriters a total of 957,589 warrants of the Company (the "Broker

Warrants"), equal to 5.5% of the number of FT Units sold pursuant to the Offering (except for those FT Units sold to

purchasers on the President's List, which were subject to a reduced number of Broker Warrants equal to 2.75%). Each

Broker Warrant entitles the holder thereof to purchase one Common Share at a price of C$0.56 at any time on or before

May 30, 2026.
