Sao Paulo-Brazilian mining giant Companhia Vale do Rio Doce (Vale) on July 1 responded to rumors in the domestic press to say that it is not in negotiations to acquire Paranapanema SA. However, Vale went on to say that as a normal course of business it is evaluating investment opportunities in Caraiba Metais SA and Cibrafertil – Companhia Brasileira de Fertilizer. Both are controlled by Paranapanema and are undergoing a publicly-announced restructuring process. Vale says that this is only an analysis, and that it has not made an effective proposal to acquire the two companies.
