VALE Vale SA

Rio de Janeiro, June 7th, 2019 To: Investor Mining & Tailings Safety Initiative Church of England Pensions Board Swedish Council on Ethics for the AP Public Pension Funds Re: Urgent request for information concerning tailings dam management Dear all, In response to correspondence received in April 2019, please find attached the requested disclosures concerning tailings facilities operated by Vale and its joint ventures (annexes A, B and C). We appreciate the opportunity to engage in this initiative as we are committed to working together to ensure that best practice standards continue to be developed and applied in the mining industry. Vale is going through a critical moment that has created opportunities to identify and reconfirm the Company’s priorities: safety, people and repair. We remain committed to the affected communities and focused on recovery efforts. The pillar of Safety and Operational Excellence is an important and strategic initiative. A new Executive Office has been created and will keep an open and direct reporting channel concerning operational risk management to the CEO and to the Board of Directors. As the Company has demonstrated over recent months, we have not spared -and will not spare-resources or efforts to repair any damages caused to the families involved, to the infrastructure of the communities and to the environment. Vale is supporting, with complete transparency, the investigation of the causes of the tragedy. There are ongoing investigations being conducted by several Brazilian governmental authorities, by the independent extraordinary committee created by Vale’s Board of Directors, and a panel of experts hired by a foreign law firm appointed by Vale. Vale is also committed to strengthening its pact with society, in which we will seek to deliver a new value proposition by acting as a force for the creation of economic growth in the communities where we operate, going beyond mere tax payments and the repair actions. We plan to seek opportunities to establish partnerships and alliances to foster sustainable development in local territories. We firmly believe that these visionary steps will be critical to the reimagining of mining operations in Brazil and in the rest of the world. * * * * Please note that references in this letter and the accompanying materials to “Vale” are to Vale S.A., and references to the “Company” or “we” are to Vale and, except where otherwise explicitly noted, its consolidated subsidiaries.

Annex A – Vale S.A. a) Overview of tailings management system, and how we manage risk In summary, risk management is composed by 3 lines of defense: The 1st Line of Defense is formed by the owners of the risks and by the executors of the processes of the business, project, support and administrative areas of the Company. They are directly responsible for identifying, evaluating, monitoring and managing risk events in an integrated manner. They must implement and enforce effective prevention and mitigation controls, ensure adequate definition and execution of action plans and establish corrective actions for the continuous improvement of risk management. It should continuously assess the applicability of the risks of the Integrated Risk Map to the activities and geographies under its responsibility. It should anticipate to the Executive Office and the Board of Directors the potential impacts that are imminent to occur, following the current governance to address the treatment of the risks mapped, as well as presenting the risks under its responsibility to the Executive Risk Committee, to the Executive Office, the Board of Directors or one of its Advisory Committees, whenever necessary. It is responsible for establishing and implementing Crisis Management protocols and Business Continuity plans for the risk events under its responsibility, whenever applicable. For events with significant impacts, drills should be performed to verify the efficiency and effectiveness of Crisis Management protocols. The periodicity of the drills should be defined by the 1st line of defense according to the criticality, observing local rules and specificities of the legislation. It must meet the guidelines defined by the 2nd line of defense. The 2nd Line of Defense, which corresponds to the areas of occupational safety, risk management, internal controls, standardization, legal compliance and specialist areas, such as operational excellence and asset management, supervises and supports the work of the 1st line of defense, providing training and instrumentation for risk management. It must identify and monitor new and emerging risks, ensure compliance with laws, regulations, internal standards and promote continuous improvement in risk management. For specific risks, there are areas such as Environmental, Health and Safety, Corporate Integrity and Data Security, which act as the 2nd specialist line of defense, monitoring risks and controls, and ensuring compliance with external regulations, policies and internal standards. The 3rd Line of Defense is composed of areas with total independence from the administration, that is, the Internal Audit and Ombudsman's Office which produce, taking into account their respective areas of operation, evaluations, inspections, through the execution of control tests, risk analysis and verification of complaints, providing exempt assurance, including on the effectiveness of risk management, internal controls and compliance.  The pillar of safety and operational excellence is strategic as it is the basis for everything. Effective processes being executed by skilled people generate predictable results leading to positive impacts on our costs, on our volumes and, obviously, on the safety of people and assets. 3

To support the diagnosis of safety conditions, management and mitigation of risks related to Vale's tailings dams, and also to provide recommendations for strengthening the conditions of its operations, the Board of Directors created the Independent Advisory Committee for Extraordinary Advisory Security of Dams (CIAESB). Tailings management system Since 2015, when Samarco’s Fundão dam collapsed in Mariana (MG), Vale’s Iron Ore business, increased investments in the management of all its structures, more specifically, maintenance services, monitoring, improvement works, audits, risk analysis, revisions of the Action Plans for Emergencies of Mining Dams (PAEBM) and implementation of warning systems, among others. The Company works to ensure the physical stability and hydraulic safety of structures and ensure compliance with legal requirements, with monitoring and regular external audits. In 2018, all of Vale’s iron ore dams classified as high and medium DPA (Associated Potential Damage) have undergone periodic dam safety reviews, obtaining all Stability Condition Declarations (DCE) for their respective structures. Certain dams, that fall within the Brazilian Law 12344/2010, are required to have external audits every six months through the regular safety inspection report. In March and September 2018, audits were carried out in Vale’s iron ore structures in Brazil and the respective DCEs were issued to all dams. In March 2019, there was another external audit process when all available data was reevaluated, new interpretations for calculating safety factors were considered in the analysis and a new constitutive model and more conservative resistance parameters were adopted. As a result of the stricter analysis framework, 18 of the Company’s dams (tailings and others) have not received the Stability Condition Declaration. Since the Dam I failure in Brumadinho, the frequency of monitoring of the safety variables, as well as the inspections for stability, evaluation were intensified in order to subsidize the taking of preventive and corrective actions in a timely manner in all of Vale’s structures. We anticipated the implementation of the Geotechnical Monitoring Center (CMG) at the Águas Claras mine in Nova Lima (MG, Brazil), which is responsible for monitoring all upstream and some conventional dam structures 24 hours a day, seven days a week. In order to support the management processes of iron ore dams, Vale also has two IT systems, one of which is called Geotec, specifically designed to the routine activities of our geotechnical structures, such as monitoring and maintenance, and another called GRG (“Gestão de Risco Geotécnico” - Geotechnical Risk Management) where technical information, such as the Dam Safety Plans, are stored. In the Coal business (Mozambique), the risk is managed by a regular geotechnical monitoring, visual inspection, maintenance plan and safety external evaluation. The Base Metals business employs a combination of industry-leading guidelines to guide our management systems for Tailings Storage Facilities (TSFs). In every location of the world in which we operate we respect and comply with the relevant legislation. We also manage our facilities by adopting the leading technical guidance by the Canadian Dam Association Guidelines in conjunction with the leading protocols established by the Mining Association of Canada Guidelines for managing TSFs. 4

In addition to internal and external assessments and reviews, we reinforce our governance with the use of Independent Tailings Review Boards (TRB). The TRB process is an independent oversight body of industry-leading tailings dam practitioners who are engaged by Vale to provide guidance and oversight to all critical active and inactive facilities plus facilities in design. The TRB process was initiated in Sudbury in 2003 and now extends across global facilities that meet at least annually at each site and also provides necessary ongoing support throughout each year. b) Confirm whether your approach to tailings management has changed or will change in light of the recent tailings disasters at Brumadinho, Mariana, Mt Polley and others. Have you, for example, reviewed all tailings storage facilities with upstream dam construction, and taken steps necessary to protect local communities and the environment e.g. buttressing, evacuation? Right after Samarco's (a joint venture equally owned by Vale S.A. and BHP Billiton Brasil Ltda.) dam breach, Vale decided, in 2016, to decommission all upstream dams dedicated to iron ore in Brazil. Over the past few years, the Company turned all of them inactive, halted disposing tailings at those dams and planned their decommissioning, while securing all necessary related stability reports issued by specialized and independent companies. With the breach of the Brumadinho dam, Vale decided to accelerate the already planned decommissioning process of the remaining iron ore upstream dams and has already provisioned US$ 1.855 billion related to this process. The Board of Directors decided to create an Independent Advisory Committee for Extraordinary Advisory Safety of Dams (CIAESB) on January 27, 2019, which is dedicated to advising the Board of Directors in matters related to the diagnosis of the safety conditions, management and mitigation of the risks related to Vale's ore tailings dams, as well as to recommend measures to be taken to reinforce their safety conditions. Vale has increased substantially its expenditures in dam management and has gone through several process and governance changes in order to improve the safety of our geotechnical structures. The Company is also continuing to examine additional opportunities for further improvements, as detailed below. The investments in dam management in Brazil have been steadily strengthened. From 2016 to 2019, investments in dam management will total R$ 786 million (approximately US$ 220 million), being applied to initiatives related to the maintenance and safety of dams, such as maintenance services, monitoring, improvements, auditing, risk analysis, revisions of the Emergency Action Plan for Mining Dams (PAEBM), implementation of alert systems, video monitoring systems, radars, installation of geophones in structures for microsymmetric monitoring, satellite tracking systems, drones for visual monitoring of the massif, the bottom drain and the spillways. Additional new piezometers and inclinometers are also being purchased, which will contribute to increase the safety level of the dams.

With the continuous increase of the share of dry processing production, from 45% in 2014 to 60% in 2018 and 70% by 2023, the Company’s investments in new dams and dam raisings tend to be concomitantly reduced. Furthermore, in order to treat the tailings from wet processing, Vale plans to invest, starting in 2020, approximately R$ 1.5 billion (about US$ 390 million) in the implementation of dry stacking disposal technology. This initiative goes along with the acquisition of New Steel announced in December, 2018, with innovative technologies for the dry beneficiation of iron ore. Vale has invested nearly R$ 66 billion (US$ 17.5 billion) installing and expanding the use of dry processing, using natural moisture, in iron ore production in its operations in Brazil over the last 10 years. By not using water in the process, no tailings are generated and, therefore, there is no need for dams at such facilities. Over the next five years, it is estimated that an additional R$ 11 billion (US$ 2.5 billion) in similar processing facilities will be spent. Today, about 60% of Vale's production is dry processed and the goal is to reach 70%. At the end of February, the Geotechnical Monitoring Center was launched. The Center currently collects data available from all upstream and some conventional dam structures, with plans to expand to all geotechnical structures in Brazil. There are professionals monitoring information 24 hours a day, 7 days a week, to ensure an informed, fast and secure decision-making process. The Center intends to provide redundancy to the existing process of identification of risks and anomalies by the risk owners at the dam site. In the Coal business, the Company is increasing its safety levels, with more frequent visual inspections, automation of geotechnical monitoring and a review of the emergency plan including alert system downstream. In the Base Metals business, each structure built using the upstream method has undergone an extensive physical inspection as well as an independent audit of those inspection processes. Benchmarking of internal and external technologies available for monitoring have been undertaken and a suite of projects have been initiated including automation of all instruments as well as satellite monitoring trials. In addition to all of the abovementioned initiatives, a Safety and Operational Excellence Office was created and will act in the areas of Safety, Operational Risk, Asset Management and Operational Excellence. This structure will keep a direct reporting channel open concerning operational risk management to the CEO and to the Board of Directors. It will be composed of highly qualified professionals who will act independently, thus strengthening and unifying the second line of defense for operational risks.
