​In view of the biannual submission of Stability Condition Declarations (“DCEs”) to the National Mining Agency (“ANM”), on March 31, 2022, Vale informs that a dam (Porteirinha) has been added to the list of structures with negative DCE. Thus, there are currently 30 dams without DCE and with active emergency level protocols, reflecting the greater scrutiny and rigor adopted in the risk management program associated with dams, through continuous monitoring via EoR (Engineer of Record). Also in line with the evolution of governance and management processes, a review was made of the number of dams included in the National Dam Safety Policy (“PNSB”). The updates refer to the following structures:

1. Porteirinha Dam, located at the Água Limpa mine, in the municipality of Santa Bárbara/MG, intended for sediment containment, located at the Água Limpa mine, in the municipality of Santa Bárbara/MG, which had a negative DCE emission, within the process of continuous performance evaluation carried out by the respective EoR from the review of new information obtained with new drilling and testing data. In this sense, the level 1 emergency protocol was activated, according to the Emergency Action Plan for Mining Dams, without the need to evacuate the Self-Rescue Zone downstream of the structure and without material impact on the company's operations. It is a small-sized, conventional earth dam, with about 2.4 million cubic meters of accumulated sediment volume. Vale will establish complementary studies and implement additional security measures for the structure, in line with its conservative approach to risk management.

2. Pondes de Rejeitos, in the municipality of Parauapebas/PA, was permanently excluded from the PNSB due to its de-characterization.

3. Dique 02 and Dique 06, located in Barão de Cocais/MG and São Félix do Xingu/PA, previously reported within the scope of the PNSB, had this reporting removed due to a review of the regulatory understanding.

4. Bacia 05 Pé de Serra, Captação de Água, Lagoa Azul and Natividade, located in the municipalities of Corumbá/MS, Parauapebas/PA, Brumadinho/MG and Ouro Preto/MG, respectively, with previous reporting as mining structures included in the PNSB, were removed from such framework in the condition of structures for water catchment, non-related to the mining activity.

In this context, the total number of Vale's mining structures included in the PNSB decreases from 110 to 103. The company reiterates that its priorities are the safety of people and communities downstream of its operations and the safety of all its structures.
