Vale informs on Borrachudo II dike


Rio de Janeiro, April 23rd, 2020 - Vale informs that, yesterday, on a preventive basis, the Level 1 emergency protocol for Borrachudo II dike, of Mina Cauê, in Itabira (MG) was initiated. This protocol does not require the evacuation of the population downstream of the dam. The Borrachudo II dike had its Declaration of Stability Condition (“DCE”) issued on March 31, 2020, which remains valid.

In this sense, Vale accepted the recommendation of the National Mining Agency - ANM, regarding the activation of the Level 1 emergency protocol, in order to provide a better understanding of the current drainage conditions of the dam. The Borrachudo II dike is a small structure built in a single step and designed to contain the sediments from the sterile Borrachudo Ipoema waste dump.

The activation of Level 1 of the Borrachudo II dike does not impact the 2020 production plan, as presented in the Production and Sales Report in 1Q20.

Vale reinforces that it has been enhancing its Tailings Management System (“TMS”) and as a result of this process, in January of this year the Engineer of Record (“EoR”) function was implemented, as an additional step for assessing its structures in Brazil. The EoR is a good practice recommended by the MAC (Mining Association of Canada) and the CDA (Canadian Dam Association) and aims to give greater reliability and quality to the dam monitoring and safety review process.
