Vale S.A. (“Vale”) informs that it has initiated, in a preventive manner, the Level 1 emergency protocol of the Dicão Leste dam, of the Fazendão Mine in Catas Altas (MG), a protocol that does not require the evacuation of the population downstream of the dam.
 
The decision is a preventive measure, resulting from the enhancement of Vale's dam safety management practices and the need to further develop the level of knowledge of the structure's geotechnical properties. The Dicão Leste dam had its positive Stability Condition Statement issued in March 2020. However, as a result of this reassessment, it will become negative.
 
The activation of the emergency Level 1 of the Dicão Leste dam does not impact the 2020 production plan, as disclosed in the 1Q20 Production and Sales Report.
