Vale S.A.

The Sossego Mine Complex consists of two open-pit mines, Sossego and Sequeirinho, located in the Carajás region in the southeastern portion of Pará State in Brazil. Access to the Sossego Mine Complex is via a bitumen road from the township of Parauapebas. Sossego was the first copper project taken into operation by Vale and has been producing copper concentrate since 2004.

The Sossego deposit is associated with a 10 km regional structural shear zone striking northeast to southeast and dipping steeply to the south. A series of copper gold deposits are associated with this structure. The Sossego deposit has been divided into four main zones, from west to east areas: Pista, Sequerinho, Baiano and Sossego Hill of which, the Sequeirinho deposit is the most important in terms of size.

Copper ore is mined using the open-pit method, and the run-of-mine is processed by means of standard primary crushing and conveying, SAG milling, ball milling, copper concentrate flotation, tailings disposal, concentrate thickening, filtration and load out.

In 2020, the Sossego mine produced 87,700 tonnes of copper and Vale reported an updated reserves estimate for Sossego totaling 98.3 million tonnes grading 0.69% copper and 0.19 g/t gold as of December 31, 2020.

Recent Activity

July 2021

Vale reported that only critical maintenance activities were performed at the Sossego’s SAG mill in Q2 2021. This allowed the company to defer a major portion of the SAG mill maintenance to 2022. Vale expects production improvements in H2 2021.
