CVRD and Sumitomo sign long-term contract for the supply of 20 million tons of iron ore

Rio de Janeiro, October 04, 2004 — Companhia Vale do Rio Doce (CVRD), the world’s largest producer of iron ore, signed with Sumitomo Metals (Sumitomo), one of the largest Japanese integrated steelmakers, a ten-year contract for the supply of two million tons of iron ore per year.

CVRD and Sumitomo have been building a solid relationship over many years, entering into long-term contracts. This agreement will strengthen such close relationship between the two companies.

Long-term contracts support CVRD investment in the expansion of iron ore production capacity and eliminate risks of raw material shortages for the steel industry.

This press release may contain statements that express management’s expectations about future events or results rather than historical facts. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected in forward-looking statements, and CVRD cannot give assurance that such statements will prove correct. These risks and uncertainties include factors: relating to the Brazilian economy and securities markets, which exhibit volatility and can be adversely affected by developments in other countries; relating to the iron ore business and its dependence on the global steel industry, which is cyclical in nature; and relating to the highly competitive industries in which CVRD operates.
