Brazil's Vale gives 10-yr bond price guidance

NEW YORK, Sept 8 (Reuters) - Brazilian miner Vale (VALE.N) (VALE5.SA) gave initial price guidance of 225 basis points over U.S. Treasury yields for its planned 10-year debt offering, according to a market source on Tuesday.

The company, the world's largest iron ore miner, plans to sell up to $1 billion worth of debt.

Earlier the company said it was raising the capital to use for general corporate purposes.

Lead managers of the deal, which is being sold by Vale Overseas Limited, are Goldman Sachs, HSBC and Santander. The size of the deal will not grow, the source said.

Moody's assigned a Baa2 rating to the bonds while Fitch gave the paper a BBB rating. (Reporting by Daniel Bases and Caryn Trokie, Editing by Chizu Nomiyama)
