The new boss of global mining titan BHP Billiton unveiled a sweeping management shake-up on Thursday, installing a new team charged with driving productivity and keeping costs down. Andrew Mackenzie officially takes over as chief executive from Marius Kloppers on May 10 but is already stamping his mark on the world's biggest miner.
The raft of changes include the departure of the head of the petroleum division, which analysts have said will be a new investment priority. Mike Yeager will leave in July and be replaced by Tim Cutt, president of BHP's diamonds division.
