Rio Tinto to increase iron ore mine capacity


Rio Tinto has committed US$290 million to further expand existing Hamersley Iron
(Rio Tinto 100 per cent) mines in the Pilbara region of Western Australia.

The expansion of the Tom Price and Marandoo mines and the construction of new
mine capacity at Nammuldi, which is adjacent to the existing Brockman operation,
is expected to commence progressive commissioning from early 2006, pending
receipt of all necessary government approvals. These projects will add 15
million tonnes per annum to Hamersley Iron's mine capacity for at least three
years.

Sam Walsh, chief executive of Rio Tinto Iron Ore, said, 'The projects will
further strengthen Hamersley's production capabilities.  The additional capacity
will ensure Hamersley is well positioned for the continued growth of the
international iron ore market in the coming years.'
