In making the announcement, Chief Executive Officer Andrew Mackenzie thanked Mr Dalla Valle for his outstanding contribution to BHP Billiton. “Dean Dalla Valle is one of the longest serving and most respected leaders at BHP Billiton. His deep knowledge of operations, strong commercial judgement and leadership have made a major contribution to our Company over four decades. “Most recently Dean led BHP Billiton’s response in Brazil to the Samarco dam failure, drawing upon his long experience in the mining sector and at BHP Billiton. “In all of his roles with BHP Billiton, starting as an apprentice electrician at Illawarra Coal, Dean has demonstrated a commitment to safety, integrity and high performance. He will be missed.” BHP Billiton will centralise the management of Samarco alongside the Group’s other major minerals non-operated joint ventures in the Minerals Americas portfolio.
