ISOENERGY AND DISA TECHNOLOGIES ANNOUNCE CLOSING OF TRANSACTION TO FORM DISA URANIUM CORPORATION

IsoEnergy Ltd. and Disa Technologies Inc. have completed the previously announced transaction to form Disa Uranium Corp., a new technology-enabled U.S. uranium company positioned to strengthen domestic uranium supply and support the growing demand for secure, United States-sourced nuclear fuel.

Pursuant to the definitive agreement, IsoEnergy contributed its portfolio of permitted, past-producing conventional uranium mines in Utah, comprising the Tony M mine, Daneros mine, Rim mine, Sage Plain project and Flatiron project to Disa Uranium, in exchange for 1,677,350 shares of common stock of the company. Disa Uranium combined IsoEnergy's Utah portfolio with Disa's proprietary HPSA technology and remediation and recovery business.

Concurrent with the closing of the transaction, Disa Uranium closed on the commitments for its previously announced $105-million (U.S.) private placement financing, with participation from Tembo Capital, BHP Ventures, Galvanize Climate Solutions, Valor Equity Partners, Evok Innovations, Halliburton Labs and Veriten. IsoEnergy invested $33-million (U.S.) in the financing. Following completion of the transaction and financing, IsoEnergy owns approximately 33 per cent of Disa Uranium on a fully diluted basis and is Disa Uranium's largest shareholder.

Philip Williams, chief executive officer and director of IsoEnergy, commented: "The completion of this transaction unlocks the value of our Utah portfolio while providing IsoEnergy with meaningful exposure to a differentiated U.S. uranium platform. As Disa Uranium's largest shareholder, we are excited to support its growth and participate in the significant opportunity ahead."

Greyson Buckingham, chief executive officer of Disa Uranium, commented: "The completion of this transaction marks an important step in building Disa Uranium into a leading U.S. uranium company. With established uranium assets, innovative technology that unlocks a substantial stranded asset and strong financial backing, we are excited to advance our strategy and capitalize on the significant opportunity ahead."

Effective as of closing of the transaction and financing, the board of directors of Disa Uranium now consists of seven directors, including IsoEnergy board of directors chairman Richard Patricio, IsoEnergy chief executive officer and director Phillip Williams, and Tembo Capital partner George Pyper, as well as current members of the Disa board of directors, Mr. Buckingham, Scott Saxberg, Marty Reed and former U.S. Nuclear Regulatory Commission commissioner Jeffrey Merrifield.

With the transaction complete, Disa Uranium intends to advance a multipronged strategy focused on deploying its HPSA technology to recover uranium from abandoned mine waste, bringing conventional U.S. uranium production back on-line and developing domestic processing capacity. The Tony M mine is expected to be a near-term priority within the Utah portfolio, alongside the advancement of Disa Uranium's remediation activities and broader development strategy.
