ABSTRACT:The Salobo Operations comprise a large open pit mine and concentrator facility located in the Carajás Mining District in northern Pará State, Brazil. The mine is 100% owned by Vale S.A. This technical report (the Report) summarizes the supporting information for the December 31, 2017 Mineral Reserve and Mineral Resource estimates for the Salobo Operations and outlines any important changes since the 2016 Amec Foster Wheeler (AmecFW) technical report. The Report has been prepared in compliance with the requirements of National Instrument 43-101 Standards of Disclosure for Mineral Projects (NI 43-101) and Form 43–101F1. All estimates are supported by applicable scientific and technical information. Unless otherwise indicated, all financial values are reported in US currency and metric as the units of measure. The Salobo deposit is hosted in the Carajás Mining District within Carajás Province, a sigmoidal-shaped, west–northwest to east–southeast-trending late Archean basin. The basin contains a basement assemblage that is dominated by granite–tonalitic orthogneisses of the Pium Complex, and amphibolite, gneisses and migmatites of the Xingu Complex. The basement rocks are overlain by volcanic and sedimentary rocks of the Itacaiúnas Supergroup, which includes the Igarapé Salobo Group, the Igarapé Pojuca Group, Grão Pará Group and the Igarapé Bahia Group. The Itacaiúnas Supergroup hosts all the Carajás iron deposits as well as Salobo. Salobo is considered to be an example of an iron oxide–copper–gold (IOCG) deposit. Global examples include Olympic Dam in Australia, Candelaria–Punta del Cobre in Chile, and Sossego in Brazil.
