Sybrandt van Dyk is stepping down as Macmahon CEO next month, to be replaced by Michael Finnegan, the company’s current general manager of surface mining.
Van Dyk decided to take up a position with an unlisted de-watering business, after joining Macmahon as CFO in April 2014.
Macmahon chairman Jim Walker thanked van Dyk for his contribution during his tenure.
“During his time with Macmahon Sybrandt has been instrumental in steering the company through a major transformation,” he said.
Finnegan also joined the company in 2014, with more than 20 years of experience in the mining industry. He previously held senior roles within the Leighton Group (now CIMIC) in its Asian mining business, and senior operational management positions with other mining contracting companies both in Australia and throughout Asia.
Walker said he was pleased with the company’s decision to select an internal candidate for the role, adding that his strong operational and technical background would be valuable for the business.
“We look forward to working with Mick in his new role as he applies his considerable experience and knowledge across the company,” he said.
Earlier this year the company considered exiting from Nigeria “due to heightened security concerns” after seven workers were kidnapped and later released near Calabar.
