Mergers & Acquisitions

ISOENERGY AND FUTURE FUELS COMPLETE TRANSACTION RELATED TO

MOUNTAIN LAKE PROPERTY IN NUNAVUT

VANCOUVER, B.C., February 18, 2025 – IsoEnergy Ltd. (TSX: ISO) (OTCQX : ISENF) (“IsoEnergy”) and Future Fuels Inc.

(TSXV: FTUR) (FSE: S0J) (“Future Fuels”, and together with IsoEnergy, the “Companies”) are pleased to announce the

completion of the previously announced transaction (the “ Transaction”) whereby Future Fuels acquired a 100%

interest in IsoEnergy’s Mountain Lake Project, comprised of mineral claims covering 5,625 hectares in the Hornby Bay

Basin, Nunavut, Canada (the “ Mountain Lake Property”) in exchange for common shares of Future Fuels (“Common

Shares”) and the grant of the Net Smelter Royalties (as defined below) to IsoEnergy. The Transaction was completed in

accordance with an asset purchase agreement (the “ APA”) dated November 13, 2024 between IsoEnergy and Future

Fuels. The acquisition of the Mountain Lake Property adds key claims to Future Fuels’ portfolio of holdings in the Hornby

Bay Basin in Nunavut, increasing its total holdings to over 342,064 hectares.

Rob Leckie, CEO and director of Future Fuels, commented: "We are thrilled to complete this transformational

acquisition of the Mountain Lake Property, marking an exciting new chapter for Future Fuels. The Mountain Lake

Property is located in a highly prospective region, and we look forward to unlocking its full potential with our

planned exploration programs. Our team is eager to update the market on our progress as we advance

exploration and development in the coming months.”

Transaction Details

Pursuant to the APA, Future Fuels acquired the Mountain Lake Property from IsoEnergy in exchange for consideration

comprised of:

(i) the issuance to IsoEnergy of 12,500,000 Common Shares (the “ Upfront Shares ”) on closing of the

Transaction (the “Closing”);

(ii) the future issuance to IsoEnergy of 2,500,000 Common Shares (the “Deferred Shares ”, and together

with the Upfront Shares, the “Consideration Shares”) on the earliest date practicable following Closing

that will ensure that such issuance will not result in IsoEnergy owning or controlling more than 19.9%

of the outstanding Common Shares on a partially-diluted basis; and

(iii) the grant by Future Fuels to IsoEnergy at the Closing of: (a) a 2% net smelter returns royalty, payable

on all production from the Mountain Lake Property, of which 1% will be eligible for repurchase by

Future Fuels for $1,000,000 ; and (b) a 1% net smelter returns royalty, payable on all production from

Future Fuels ’ properties in Nunavut other than the Mountain Lake Property (collectively, the “ Net

Smelter Royalties”). The Net Smelter Royalties were granted pursuant to royalty agreements between

the Companies entered into concurrently with the Closing.

The Upfront Shares are subject to contractual restrictions on resale (the “Lock-Up Restrictions”) beginning from the

date of Closing, as well as a statutory hold period of four months and one day (the “Statutory Restriction”) from the

date of Closing. The Deferred Shares, when issued, will be subject to the same Lock-Up Restrictions and the Statutory

Restriction beginning from the date of issuance of the Deferred Shares.

In accordance with the Lock-Up Restrictions, IsoEnergy may not sell, pledge, encumber, assign or otherwise dispose of

or transfer the Consideration Shares until they become free-trading in accordance with the release schedule, whereby

25% will be released on Closing (subject to the Statutory Restriction) and every six months thereafter for a total period

of 18 months.

In connection with Closing, the Companies have also entered into an investor rights agreement dated February 14, 2025,

which provides IsoEnergy, for so long as IsoEnergy owns 10% or more of the issued and outstanding Common Shares

on a partially diluted basis , the right to: (i) nominate one director to the board of directors of Future Fuels ; and (ii)

participate in future equity financings of Future Fuels in order to maintain its pro rata share ownership, subject to prior

approval by the TSX Venture Exchange.

In addition, as previously announced in Future Fuels’ news release dated December 19, 2024, Future Fuels closed the

first tranche of its concurrent private placement on December 19, 2024. Future Fuels has closed the concurrent private

placement and will not issue additional securities under a second tranche.

Early Warning Disclosure

Prior to the completion of the Transaction, IsoEnergy held no securities of Future Fuels. Following completion of the

Transaction, IsoEnergy beneficially owns 12,500,000 Upfront Shares and is deemed to beneficially own the 2,500,000

Deferred Shares, representing approximately 21.36% of the issued and outstanding Common Shares on a non -diluted

basis (assuming the issuance of the Deferred Shares).

While IsoEnergy currently has no plans or intentions with respect to the Common Shares, IsoEnergy may develop such

plans or intentions in the future and, at such time, may from time to time acquire additional securities, dispose of some
