Rio Tinto invests US$2.4 billion in two new iron ore mines in the Pilbara

    LONDON, UK, Nov. 26 /CNW Telbec/ - Rio Tinto has announced a further
significant investment in its iron ore export capacity in the Pilbara region
of Western Australia, with the approval of the new Mesa A/Warramboo mine in
the Robe Valley and Brockman 4 mine near Tom Price.
    The combined investment of US$2.42 billion (nominal terms, 100 per cent
basis) in the two mines will ensure that Rio Tinto's leadership of the Pilbara
matches its unparalleled global position in the iron ore industry. The mines
will begin production in 2010.
    Sam Walsh, Chief Executive Rio Tinto Iron Ore, said the new mines were
integral to the Pilbara production platform underpinning Rio Tinto's rapid
expansion of its global network of assets.
    "Mesa A/Warramboo and Brockman 4 demonstrate our strategy of substantial
investment in high-quality, long-life, low-cost assets. They are outstanding
deposits, close to existing infrastructure, and each promises excellent
commercial returns," he said.
    "Brockman 4 will bring on a new, high-volume long-life source of Brockman
ore, a key component of the Pilbara Blend product successfully introduced to
the market in July this year. Likewise, our Robe Valley pisolite product has
consistently proved to be competitively attractive for our customers."

    Mesa A/Warramboo

    The Mesa A/Warramboo mine, about 50 kilometres from Pannawonica, will
have an initial production of 20 Mtpa, increasing to 25Mtpa by 2011.
    The mine will sustain production of Robe Valley pisolite ore at 32Mtpa
over the next decade. Current production from the Mesa J deposit, now nearing
the end of its mine life, will reduce to 7Mtpa with Mesa A providing the
balance. A 49-kilometre rail extension will connect the new mine to the Rio
Tinto rail network.
    The project capital cost is estimated at US$901 million (Rio Tinto share
US$478 million).
    Total high-grade reserves across the Mesa A / Warramboo deposits are
estimated at 249Mt, with a total mine life of 11 years.

    Brockman 4

    The first phase of the Brockman 4 development, about 60 kilometres
northwest of Tom Price, will have an annual output of 22 Mtpa with a potential
for further expansion. Brockman 4 is well positioned to serve as a hub for the
future development of nearby deposits. The project has an estimated total
capital cost of US$1,521 million. Design considerations allowing for an
increase in output by 14Mtpa, to 36Mtpa, are included in the Phase I scope,
which will facilitate a cost effective ramp up as additional port capacity is
brought on line.
    Phase I will take two years to construct and commission with production
ramp-up planned to begin in early 2010, and full capacity to be reached by
2012. The mine will be connected to the Pilbara Iron Rail network by a
35 kilometre rail spur to the Brockman 2/Nammuldi operations.
    The Brockman 4 orebody contains 573Mt of high-grade reserves
(greater than 60 percent iron). A further 597 Mt of blending and lower-grade
(50-60 percent Fe) resource will be stockpiled for future processing.
    Both expansions are subject to Government approvals.
