Atlantic Lithium Limited (AIM:ALL) said it has promoted Amanda Harsas to the board as finance director with immediate effect.
She had previously had the title of chief financial officer and company secretary.
The Africa-focussed lithium exploration and development company, which revealed founder Vincent Mascolo had passed away earlier this week, noted that Harsas has a demonstrable track record and over 20 years' experience in strategic finance, business transformation, commercial finance, customer and supplier negotiations and capital management.
A chartered accountant with a bachelor of business degree, she previously worked across several sectors including healthcare, insurance, retail and professional services, with international experience in Asia, Europe and the US.
Chair Neil Herbert said: "Since her appointment in 2020, Amanda has performed exceptionally and we are very pleased that she is joining the board at this important time as we take our fully funded Ghanaian lithium project through the steps towards production.
"I also express thanks for the overwhelming number of condolence messages received following the passing of the company's founder, Vincent Mascolo, which reflects the impact Vincent had in life and work. We knew and worked with Vincent for many years and recognise the importance to bring all of his hard work in Atlantic Lithium to fruition."
