Vale informs that the Declarations of Conformity and Operability ("DCO") of the Emergency Action Plans for Mining Dams ("PAEBM") have been denied for four of its structures, namely Monjolo, ED Monjolo, Porteirinha (Piracicaba River, MG) and Dam 7 (Jeceaba, MG), in accordance with Resolution No. 95/2022 of the National Mining Agency (ANM). The DCO became mandatory in 2022 and specifically evaluates the PAEBM and related measures. The denial signals that there are actions to be taken by Vale to ensure that the referenced PAEBMs have adequate operating conditions. The company is acting to resolve the identified discrepancies as soon as possible.

Vale reiterates that the stability conditions of the four structures remain unchanged. Of the four structures, only Dam 7 was in operation for tailings disposal at the time of the assessment. Based on the negative DCO and prioritizing the best safety conditions for its employees and communities, Vale has suspended the operation of Dam 7 and related production processes until the actions related to the corresponding PAEBM are implemented.
