FOREMOST CLEAN ENERGY ANNOUNCES APPOINTMENT OF DAVID CATES AS INTERIM CEO

Foremost Clean Energy Ltd. has appointed David Cates as interim president and chief executive officer of the company. Mr. Cates has served as a director of the company since October, 2024, and is CEO of Denison Mines Corp., which is the company's largest shareholder, owning approximately 19.9 per cent of Foremost's outstanding common shares.

The appointment of Mr. Cates is expected to provide leadership continuity while the board completes a formal search and selection process for a new permanent president and CEO, following the departures of Jason Barnard, who had served as president and CEO of Foremost, and Christina Barnard, who had served as the company's chief operating officer. Mr. Barnard and Ms. Barnard continue to serve as CEO and president, respectively, of Rio Grande Resources Ltd.

Doug Mason, the chair of Foremost's board of directors, commented: "We are pleased to have the support of Mr. Cates and Denison during this brief time of leadership transition at Foremost. The company has been transformed since partnering with Denison in 2024 and is organizing itself to progress its strategy of aggressive uranium exploration in the prolific Athabasca basin region of Northern Saskatchewan.

"Mr. Barnard was first appointed interim CEO in December, 2022. During his tenure as CEO, Mr. Barnard led the company through the execution of the option agreement with Denison in 2024, the spinout of its gold and silver properties in a transaction with Rio Grande Resources, as well as the recently announced completion of the phase 2 earn-in under the Denison option, which increased the company's ownership interest to 51-per-cent interest across its 10 Athabasca uranium projects, with the exception of Hatchet Lake, at 35.78 per cent. On behalf of the board, we thank Mr. Barnard for his service and wish him the best in his future endeavours."

Mr. Cates added: "Foremost is an important part of the team Denison exploration strategy, aimed at supporting junior resource exploration in the Athabasca basin while Denison focuses on the construction of its flagship Phoenix in-site recovery uranium mine. Given Denison's significant investment in Foremost, I'm pleased to take on this interim role to assist with management continuity while the Foremost board completes its search for a new dynamic leader to spearhead the company's uranium exploration strategy."
