Lithium producer Sayona Mining’s CEO resigns, shares tank

Australia's Sayona Mining said early on Monday its CEO and managing director Brett Lynch resigned from his position, sending the lithium producer's shares down 27.2% at close. Lynch, who cited personal reasons for his move, will depart the company with immediate effect while the existing non-executive director James Brown has been appointed interim CEO, the company said. Lynch played a key role in the acquisition of the North American Lithium (NAL) operation in Québec, Canada, which restarted operations this year.
