Former Leighton boss Wal King is the new chairman of African-focused iron ore miner Sundance Resources.
Mr King joined the Sundance board in May, and was chief executive of construction giant Leighton for 24 years up until 2011.
Leighton is currently the subject of allegations of corruption and bribery, which are being investigated by the Australian Federal Police, and Mr King has denied any knowledge of alleged corrupt payments in Iraq.
He will replace George Jones as Sundance chairman when Mr Jones steps down at the company's annual general meeting on November 29.
Mr King said he looked forward to helping create substantial value for the company's shareholders.
Sundance is developing an iron ore project on the border of Cameroon and the Republic of Congo in central Africa.
Its entire board of directors were killed in a 2010 place crash in west Africa.
