ISOENERGY ANNOUNCES LEADERSHIP TRANSITION

IsoEnergy Ltd. has appointed Tim Gabruch as chief executive officer and director of IsoEnergy. Mr. Gabruch will be taking over the role from Craig Parry who will step down as president and chief executive officer and continue to serve the company as a member of the board of directors.

Leigh Curyer, chairman of the board, commented: "On behalf of the board of IsoEnergy, I am very pleased to welcome Tim as chief executive officer and director. Tim's knowledge of nuclear fuel markets and corporate development in the nuclear industry will be integral to executing IsoEnergy's strategy of exploration and development. With outstanding Saskatchewan assets serving as the foundation of IsoEnergy, we are also proud to be repositioning leadership of the company to Saskatoon, Sask.

"Further, and on behalf of the board, I would like to thank Craig as a co-founder of IsoEnergy for his leadership over the past five years. IsoEnergy was founded in 2016 to explore and grow its portfolio of high-impact uranium projects in Saskatchewan's Eastern Athabasca basin. During Craig's tenure, IsoEnergy has acquired and financed a highly strategic Eastern Athabasca basin land position of high-calibre prospective uranium properties and discovered the Hurricane zone in July, 2018, which will be a focus of 2021 drilling activities."

Mr. Gabruch, chief executive officer, commented: "I am very excited to join IsoEnergy and look forward to growing its high-grade uranium discovery at Hurricane. The NexGen group have created a winning formula for exploration and development in the uranium space and I am confident my skills and experience will help IsoEnergy in its next phase of exploration and overall development of the company. It's an exciting time in the nuclear industry, with the demand for clean nuclear energy growing. The past decade has been a tough one for uranium suppliers and has resulted in supply-side stress in the global uranium market. With the sector beginning to turn around, the world will need projects like Hurricane and more Canadian uranium discoveries like it to help meet future demand."

Mr. Parry, former chief executive officer, commented: "It has been my great privilege to lead IsoEnergy and its outstanding team. I thank the board and our major shareholder NexGen Energy for their support over the past five years. I step aside as CEO with the company well financed and in a strong position to continue advancing our high-grade Hurricane discovery and large portfolio of Athabascan exploration projects. I look forward to remaining involved with the company and helping drive our projects forward."
