Vale informs that, in line with the continuous monitoring of the safety conditions of its geotechnical structures, and as a result of regular inspections and frequent interpretations of data related to the structures, performed through the function of the Engineer of Record (EoR), it started today, on a preventive basis, the Level 1¹ emergency protocol of the Paracatu and Patrimônio dikes, a protocol that does not require the evacuation of the population downstream of the structures. Both geotechnical structures had negative Stability Condition Declarations (DCEs) issued.

Vale also informs that four geotechnical structures, with Level 1 emergency protocols initiated and communicated in previous periods, on a preventive basis, formally had, on this date, negative DCEs issued, as shown below:
