Press release

Rio Tinto Limited 2010 annual general meeting adjourned to Wednesday 26 May

20 April 2009

In light of the unprecedented travel restrictions in Europe, it is not possible for the chairman, chief executive or other Rio Tinto directors to arrive in Melbourne in sufficient time for the Rio Tinto Limited annual general meeting scheduled for 0930 (AEST) on Thursday, 22 April 2010. They are currently in London, having attended the Rio Tinto plc AGM last Thursday.

Given these extraordinary circumstances, the Boards of Rio Tinto have decided that the meeting should be adjourned to 0930 (AEST) on Wednesday, 26 May 2010 in Melbourne, Victoria.

Shareholders should note that valid proxies already lodged for the Rio Tinto Limited AGM remain valid for any adjournment of that meeting, unless revoked. New or replacement proxies would be able to be lodged up until 48 hours before the time of the adjourned meeting. A notice will be sent to Rio Tinto Limited shareholders with details of the adjourned meeting.
