The Carajás mineral province is a highly mineralized metallogenic province that lies at the southern margin of the Southern Amazon Craton in Brazil (Fig.1b). It is comprised of two Archean tectonic blocks, the older southern Rio Maria granitoid-greenston terrain (Huhn et al., 1988) and the northern Itacaiúnas Shear Belt (Araújo et al., 1988).The Itacaiúnas Shear Belt contains giant supergene-enriched iron and manganese deposits (Gibbs and wirth, 1990).The quantity of the deposits amount to 60, and they are divided into south and north. Up to now, only north deposits were open pitted.
