CVRD and Posco agreement on 2005 iron ore prices

Rio de Janeiro, February 23, 2005 — Companhia Vale do Rio Doce (CVRD), the world’s largest iron ore producer, concluded the iron ore price negotiations for 2005 with Pohang Steel Corporation (POSCO), the largest Korean steel maker. As an outcome of these negotiations, iron ore prices for Carajás (SFCJ) and Southern System (SSF) fines, FOB Ponta da Madeira and Tubarão, respectively, increased by 71.5% relatively to 2004.

CVRD and Posco developed a long and mutually beneficial relationship and the current agreement involves an amount of iron ore fines of approximately 12 million tons for 2005.

The magnitude of the price increase for 2005 reflects an unprecedented situation characterized by the disequilibria in the global metals and maritime freight markets, which led to substantial prices increases for these products and services during the last couple of years.

CVRD reinforces its long-term commitment with clients by investing a significant amount of resources, in spite of rising investment costs, in the production and logistics of iron ore. For 2005, CVRD capex budget allocated US$ 1.7 billion for investments in ferrous minerals. Currently, CVRD is developing six projects for iron ore production capacity expansion, which will come on stream between 2005 and 2007.
