Mr. Gear is registered as a professional engineer with the Association of Professional Engineers and Geoscientists of Alberta (APEGA).

"E3 has built something genuinely rare -- a world-class resource, a clear path to production and an exceptional team," said Mr. Gear, newly announced chief operating officer of E3 Lithium. "I'm excited and honoured to join E3 and get Clearwater to commercial operations. This will be the first of its kind in Canada, opening a new chapter in this country's critical minerals story."

"After an extensive search, we are very pleased to welcome Tom to the executive team as chief operating officer," said Chris Doornbos, chief executive officer and chair of E3. "His extensive experience leading large-scale industrial operations, driving organizational excellence and developing high performing teams will be invaluable as we move closer to construction and operations of the Clearwater project. On behalf of the board of directors and the entire company, I want to thank Kevin for his outstanding contributions. Kevin has played a key role in advancing the Clearwater project and helping establish the strong technical and operational foundation from which we will grow."

Mr. Carroll has played an important role in E3 Lithium's growth and development, contributing to the advancement of the Clearwater project through key exploration, engineering, development and operational milestones. Throughout his tenure, Kevin has been recognized for his principled leadership, commitment to operational excellence and unwavering focus on maintaining safe work practices across E3's activities. Kevin's last day will be June 12, 2026, and he will remain with the company in an advisory capacity during a transition period to ensure a smooth handover of responsibilities.

"It has been a privilege and exciting capstone to work with the E3 team to advance Canada's first commercial brine-hosted lithium development to help meet fast-growing world lithium demand," said Kevin Carroll, retiring chief development officer of E3. "I am confident the dedication, innovation and talent of the E3 team will continue to drive the company's long-term success, and I look forward to following the team's continuing endeavours in developing the Clearwater project."
