Chalmers has served as Energy Fuel’s president and COO since July 2016. He succeeds Stephen Antony, who retires at the end of January in accordance with the company’s long-term succession plan. He’ll also retain the title of president.
Antony has served as chief executive since 2009 and has been with the uranium miner for 13 years.
Chalmers will also take Antony’s vacated board seat.
Having previously led production at Paladin Energy Ltd. and acted as a consultant to BHP Billiton plc, Rio Tinto and Marubeni Corp., Chalmers has decades worth of global uranium mining experience, the company said.
“Mark brings the suite of skills that we believe Energy Fuels needs to continue our growth and development into the future,” said Chairman J. Birks Bovaird in a statement.
Under the guidance of Antony, Energy Fuels went from a small uranium project developer into the largest uranium producer in the U.S. in 2017, the company said.
“We are well positioned to capitalize on increasing uranium prices and other opportunities in the future,” added Bovaird.
