  • Leadership change amid growth at Langpan chrome project

South African mining investment company Mantengu announced Friday that Chief Executive and Executive Director Mike Miller had resigned, effective Feb. 28, 2026.

Magen Naidoo, currently deputy chief executive and chief financial officer, will succeed Miller on March 1.

"Magen has been actively involved in operations as deputy CEO over the past few months, as well as the company’s various acquisitions and the group strategy over the past few years," the company said in a statement.

Mantengu said Miller intends to devote more time to his family. In recent months, Miller had spoken publicly about threats against his life after alleging manipulation of Mantengu's share price.

A former audit partner at Deloitte, where he worked for more than 17 years, Naidoo is a chartered accountant with over 25 years of experience. He takes the helm of a growing company whose flagship project is the Langpan chrome and platinum group metals mine, which holds an ore reserve of 2.17 million tonnes. Mantengu has begun refurbishing the plant associated with the project to process approximately 30,000 tonnes of ore per month, or 50 tonnes per hour, up from an initial 30 tonnes per hour.
