Rio Tinto share repurchase programme



Under its previously announced share buy back programme, any shares that Rio
Tinto plc buys back between 21 June 2007 and the announcement of Rio Tinto's
half-year results on 2 August 2007 will be handled by an independent third
party.   This party will make its trading decisions in relation to Rio Tinto's
securities independently of, and uninfluenced by, Rio Tinto.  The shares will be
held in treasury.



Any acquisitions will be effected within certain pre-set parameters, and in
accordance with both Rio Tinto's general authority to repurchase shares and
Chapter 12 of the Listing Rules which requires that the maximum price paid be
limited to no more than 5 per cent above the average market value for the shares
as derived from the London Stock Exchange Daily Official List for the five
business days immediately prior to such purchase.



Rio Tinto confirms that it is not aware of any unpublished price sensitive
information.
