Press Release Vale informs on the report of the Independent Extraordinary Advisory Committee for Dam Safety Rio de Janeiro, May 19th, 2021 - Vale S.A. ("Vale" or "Company") hereby discloses to the market the final report ("Report") of the Extraordinary Independent Advisory Committee for Dam Safety ("CIAE-SB"), which ended its activities in May 2021. Announced on February 15, 2019, the CIAE-SB was established by the Company's Board of Directors, under the coordination of Professor Flavio Miguez Mello, a reference in dam engineering with over 50 years of professional experience. The geotechnical experts Mr. Willy Lacerda and Mr. Pedro Repetto worked together with Mr. Mello. Along its two years of works, the CIAE-SB dedicated itself to the diagnostics of the safety conditions and risk management and mitigation related to Vale's dams, as well as recommended measures to reinforce their safety conditions. To access the CIAE-SB Report, click here. The CIAE-SB final report introduced a summary of the 380 recommendations made during the period, comprised of visits and technical assessments made for Vale’s main dams and tailings storage facilities in Brazil. Recommendations and observations made by CIAE-SB had the main objective of advising Vale’s Board of Directors, as well as Vale's geotechnical and project teams towards the enhancement of safety and risk management practices. The Committee also highlighted the progress made by the company in the last two years in its practices and policies for dam management and control. Out of the 380 CIAE-SB recommendations, 265 were already adopted by Vale. With the issuance of its final report, the CIAE-SB in its current format will be discontinued and the committee members will take part of one of the Independent Tailings Review Boards (ITRB), acting as external reviewers to the three lines of defense used in Vale's risk management model, in line with international best practices and with the Global Industry Standard on Tailings Management (GISTM).
