Production highlights Rio de Janeiro, April 20, 2017 – Vale S.A. (Vale) reached a record for a first quarter of 86.2 Mt of iron ore production1 in the first quarter of 2017 (1Q17), 11.2% higher than in 1Q16 mainly due to the ramp-up of the S11D and Itabiritos projects in the Southeastern System. The Northern System, which comprises Carajás, Serra Leste and S11D, achieved a record for a first quarter of 36.0 Mt in 1Q17, 11.1% higher than in 1Q16 as a result of the S11D ramp-up, which is advancing according to plan. Blended volumes in Asia totaled 12.4 Mt in 1Q17, 10.3 Mt and 6.5 Mt higher than in 1Q15 and 1Q16, respectively, as a result of the ongoing strategy to bring more flexibility to the integrated supply chain by increasing offshore blending capacity, enabling rapid responses to changes in market conditions. The ongoing offshore blending activities require the build-up of offshore inventories and, as a result, temporarily leads to lower sales volumes when compared to shipment volumes from Brazil. Nickel production reached 71.4 kt in 1Q17, 14.0% and 2.9% lower than in 4Q16 and 1Q16, respectively, mainly due planned maintenance shutdowns at our operations in Indonesia and Japan, and operational challenges at our Thompson operations. Production of finished nickel products from VNC reached the record of 10,200 t in 1Q17, 14.7% higher than 4Q16 and 6.0% higher than 1Q16. Copper production was 109,000 t in 1Q17, 11.0% and 2.6% lower than in 4Q16 and 1Q16, respectively, mainly due to the lower production from Sudbury. Production of copper in concentrate at Salobo in 1Q17 totaled a record 42,600 t for a first quarter, 3.6% higher than in 1Q16. Coal production in Mozambique reached a quarterly record of 2.4 Mt in 1Q17, 170.4% and 53.7% higher than in 1Q16 and 4Q16, respectively, mainly as a result of the continued and strong ramp-up of the second Coal Handling and Preparation Plant (CHPP2). CHPP2 production grew by 86% in 1Q17 compared to 4Q16. 1 Including iron ore acquired from third parties. 3

Production summary Vale’s iron ore production reached a record for a first quarter of 86.2 Mt in 1Q17, 8.6 Mt higher than in 1Q16 mainly due to the ramp-up of the S11D and Itabiritos projects in the Southeastern System. Production was 6.2 Mt lower than in 4Q16 due to usual weather-related seasonality in the first quarter of the year, which affected mainly the performance of the Northern System. The production guidance for 2017 remains within the 360-380 Mt range as previously announced and from the end of 2018 onwards Vale will most likely achieve the long-term base case target of 400 Mt, as per Vale’s presentation at the December 2016 “Vale Day”. Vale’s Global Recovery (GR)2 increased from 44% in 1Q15 to 49% in 1Q16 and to 51% in 1Q17, as a result of the continuing increase in operational productivity over the past few years. 2 Measured by output of final production divided by the total ton nages extracted (ROM and waste). 5 IRON ORE 186,198 92,386 77,544 -6.7% 11.2% Itabira 8,821 8,573 7,512 2.9% 17.4% % change 000’ metric tons 1Q17 4Q16 1Q16 1Q17/4Q16 1Q17/1Q16 Northern System 35,974 40,594 32,385 -11.4% 11.1%

Iron ore and pellets shipments from Brazil and Argentina totaled 77.7 Mt in 1Q17, 12.0 Mt and 6.1 Mt higher than in 1Q15 and 1Q16, respectively, mainly due to higher production in the Northern and Southeastern Systems. Blended volumes in Asia totaled 12.4 Mt in 1Q17, 10.3 Mt and 6.5 Mt higher than in 1Q15 and 1Q16, respectively, as a result of the ongoing strategy to bring more flexibility to the integrated supply chain by increasing offshore blending capacity, enabling rapid responses to changes in market conditions. The share of offshore inventories over total inventories increased from 15% in 2015 and 2016 to 23% in 1Q17, reflecting the ongoing strategy to shift inventories downstream along the supply chain. By the end of 2017, we expect to have 30% of our total inventories offshore. The ongoing offshore blending activities require the build-up of offshore inventories and, as a result, temporarily leads to lower sales volumes when compared to shipment volumes from Brazil. The average Fe content was 63.9% in 1Q17, remaining in line with the average grade achieved in 4Q16. Northern System The Northern System, which comprises Carajás, Serra Leste and S11D, achieved a record for a first quarter of 36.0 Mt in 1Q17, 11.1% higher than in 1Q16 as a result of the S11D ramp-up, which is advancing according to plan. Production was 11.4% lower than in 4Q16 due to the usual weather-related seasonality in 1Q17. Southeastern System The Southeastern System, which encompasses the Itabira, Minas Centrais and Mariana mining hubs, produced 28.2 Mt in 1Q17, 0.4 Mt higher than in 4Q16 due to the better operational performance of the dry beneficiation process in Alegria and the higher production in Conceição Itabiritos II, as its ramp-up was concluded in 1Q17. Production in 1Q17 was 5.6 Mt higher than 6

in 1Q16 due to the start-up of a crushing facility at the Fazendão mine and the other above-mentioned positive events from 4Q16 vs. 1Q17. Southern System The Southern System, which encompasses the Paraopeba, Vargem Grande and Minas Itabirito mining hubs, produced 21.5 Mt in 1Q17, 8.2% lower than in 4Q16 mainly due to stoppages in the Minas Itabirito complex to allow for the shift in beneficiation from wet to dry processing. Production was 2.4% lower than in 1Q16 due to quality of ROM being mined at current mine faces in the Vargem Grande mining hub. Midwestern System The Midwestern System, which encompasses the Urucum and the Corumbá mines, produced 0.6 Mt in 1Q17, remaining in line with 4Q16 and 1Q16, as a result of Vale’s continuing strategy to optimize margins. 7

Ferroalloy production reached 36,000 t in 1Q17, 2.8% and 44.0% higher than in 4Q16 and 1Q16, respectively. Manganese ore production Production at the Azul manganese mine totaled 367,000 t in 1Q17, 6.1% and 15.4% lower than in 4Q16 and 1Q16, respectively, mainly due to the lower availability of high grade ore. Production at the Urucum mine totaled 163,000 t in 1Q17, in line with 4Q16 and 1Q16. Production at the Morro da Mina mine totaled 14,000 t in 1Q17, 36.6% lower than 4Q16 due to a scheduled stoppage in the mine, which began at the end of February and is scheduled to go on until May. The purpose of the stoppage is to adequate the mine to increase the manganese grade and to clean the bottom of the pit. Ferroalloy production Ferroalloy production in 1Q17 totaled 36,000 t, 44.0% higher than in 1Q16, mainly due to the resumption of the operations at the Barbacena unit in February 2016. Production was composed by 15.000 t of ferrosilicon manganese alloys (FeSiMn), 15.000 t of high-carbon manganese alloys (FeMnHC) and 6.000 t of medium-carbon manganese alloys (FeMnMC). 10 FERROALLOYS (Brazil)3635252.8%44.0% Urucum163167162-2.4%1.0% % change 000’ metric tons1Q174Q161Q161Q17/4Q161Q17/1Q16 MANGANESE ORE544580596-6.2%-8.7%

Production overview Production of nickel reached 71,400 t in 1Q17, 14.0% lower than in 4Q16 and 2.9% lower than in 1Q16, mainly due to planned maintenance shutdowns in Indonesia and Japan and operational challenges at our Thompson operations. Canadian operations Production from the Sudbury mines reached 17,900 t in 1Q17, 10.1% lower than in 4Q16 and 8.2% lower than in 1Q16. Sudbury source production was adversely impacted in 1Q17 mainly due to inventory drawdown during the 4Q16 and 1Q16 periods. Sudbury took furnace #2 off-line mid-March for a three-month long rebuild and expansion in its’ capacity as this will be the furnace in operation when Sudbury officially transitions to a single furnace in 4Q17. In 2Q17 Sudbury will have its three-week long surface plant wide scheduled maintenance shutdown, which occurs every 18 months. . 11 Feed from third parties 22.73.33.9 -18.2% -30.8% TOTAL NICKEL 71.483.073.5-14.0%-2.9% New Caledonia 110.28.99.714.6%5.2% Voisey's Bay13.516.310.9-17.2%23.9% Sudbury17.919.919.5-10.1%-8.2% % change 000’ metric tons 1Q174Q161Q161Q17/4Q161Q17/1Q16

Timeline of the transition to a single furnace operation in Sudbury In 1Q17, the Clydach refinery continued to consume feed from the Sudbury smelter above normal levels, contributing to the overall performance of the North Atlantic operations. Production from the Thompson mines reached 4,800 t in 1Q17, 34.3% lower than in 4Q16 and 23.6% lower than in 1Q16, output in 1Q17 was impacted by: (i) the planned 1Q17 transition to a single furnace operation; and (ii), certain operational issues, including deleterious elements in the smelter feed and a hot metal leak in the smelter that resulted in approximately ten days of production loss. The operational issues encountered were unrelated to the transition to the single furnace. Production from the Voisey’s Bay source reached 13,500 t in 1Q17, 17.0% lower than in 4Q16 and 23.4% higher than in 1Q16. Production decreased relative to 4Q16 mainly due to reduced consumption of Voisey’s Bay source concentrate in Thompson due to the single furnace operation and certain operational issues. The production increase over 1Q16 was due to the higher consumption rates at Sudbury and the continued successful ramp-up of the Long Harbour refinery. Production at the Long Harbour processing plant reached 4,100 t in 1Q17, 21.2% lower than in 4Q16 due to the start-up of additional processing circuits in January after a two-week shutdown to complete the necessary tie-ins. These new circuits successfully started up and both cobalt and copper metal were produced for the first time. A monthly production record for nickel was achieved in March. During 1Q17, the operating throughput increased to almost 65% of its nominal capacity. Indonesian operation (PTVI) PTVI nickel in matte production reached 17,200 t in 1Q17, 12% lower than in 4Q16 and 2.0% higher than in 1Q16. Compared to 4Q16, the weaker nickel in matte production was due to the adverse impact of a planned maintenance works in its kilns and furnaces. 12

Production of finished nickel from PTVI reached 16,300 t in 1Q17, 25.4% lower than in 4Q16 and 8.6% lower than in 1Q16. Production in 1Q17 of finished nickel was negatively impacted by the scheduled annual maintenance shutdown at the Matsusaka refinery in Japan. New Caledonia operation (VNC) Production of finished products from VNC reached a record of 10,200 t in 1Q17, 14.7% higher than in 4Q16 and 6.0% higher than in 1Q16. Production of NiO and NHC at VNC was 8,700 t in 1Q17. Site production was 6.5% lower than in 4Q16 and 4.0% lower than in 1Q16. Production was negatively impacted by decreased autoclave availability and unscheduled electrical power outages. NiO represented 81% and NHC 19% of VNC’s 1Q17 site production. Brazilian operation (Onça Puma) Production from the Onça Puma operation reached 6,100 t in 1Q17, 8.9% and 10.6% higher than in 4Q16 and in 1Q16, respectively. Onça Puma’s strong production rates were achieved through improved asset utilization and productivity. 13
