Rio Tinto today announces the appointment of Ms Ann Godbehere and Mr Robert Brown as non executive directors to join the boards of Rio Tinto plc and Rio Tinto Limited. In addition, the boards have received notification from Sir David Clementi and David Mayhew that they will be retiring as non executive directors upon the conclusion of the 2010 annual general meetings.

Ann Godbehere joins the boards and the Audit committee today and will succeed Sir David Clementi as chairman of the Audit committee. Ann has more than 25 years’ experience in the financial services industry. She spent 10 years at Swiss Re, latterly as chief financial officer. Her non executive directorships include UBS AG and Prudential plc where she is chair of its Audit committee.

Sir David Clementi has notified the boards that he will be retiring as a non executive director and therefore as chairman of the Audit committee upon the conclusion of Rio Tinto’s annual general meeting in Australia on 22 April 2010. Sir David has been a non executive director of Rio Tinto since 2003.

As indicated at the 2009 AGMs, David Mayhew will also be standing down from the boards upon the conclusion of Rio Tinto’s annual general meeting in Australia on 22 April 2010. He has been a non executive director of Rio Tinto since 2000.

Jan du Plessis, chairman, said “I am very pleased to welcome Ann to the Rio Tinto boards. She brings substantial financial services’ experience that will be of particular value to the Audit committee. I would also like to pay tribute to the valuable contributions made by Sir David Clementi and David Mayhew during their many years as non executive directors. I wish them well for the future.”

Robert Brown joins the boards on 1 April 2010. He has considerable global business experience. He is currently chairman of Groupe Aeroplan Inc and serves on the board of Bell Canada Enterprises (BCE Inc), the holding company for Bell Canada. He recently retired as president and chief executive officer of CAE Inc, a world leader in flight simulation and training. Before that he spent 16 years at Bombardier Inc where he was first head of the Aerospace Group and then president and chief executive officer. He has also served as chairman of Air Canada and of the Aerospace Industries Association of Canada.

Yves Fortier has also given notice to the boards of his intention to retire as a non executive director at the end of his term upon conclusion of the 2011 AGMs. He joined the boards upon the acquisition of Alcan Inc in 2007.

Jan du Plessis, chairman, said, “I am very pleased to welcome Bob to the Rio Tinto boards. I am most grateful to Yves for committing to serve his full term during an important transition period for Rio Tinto following the Alcan acquisition. He has also been very helpful to me in identifying Bob as someone who can bring commensurate skills and experience to the boards.”

Together with Sam Walsh, chief executive Rio Tinto Iron Ore and chief executive Australia, who was appointed by the boards as an executive director since the last AGMs, Ann Godbehere and Robert Brown will offer themselves for election to the boards at the 2010 AGMs.
