The annual production of iron ore was within the original guidance of 360-380 Mt, being closer to the lower end of the range, mainly due to the reduction of production of iron ore with high silica content from the Southern and Southeastern Systems, in line with the ongoing strategy to maximize margins. Vale reaffirms its production guidance for 2018 of around 390 Mt, as previously announced on Vale Day.

 7 VALE’S FINANCIAL REPORT 1Q15 The Northern System achieved a production record of 169.2 Mt in 2017, 14.2% higher than in 2016, due to the S11D mine and plant ramp-up. Vale’s Global Recovery rate (GR)3 increased from 46% in 2015 to 50% in 2016 and now to 51% in 2017, as a result of the continuous improvement in productivity. 3 Measured by output of final production divided by the total tonnages extracted (ROM and waste). Iron ore and pellets shipments from Brazil totaled 335.5 Mt in 2017, 34.2 Mt and 17.1 Mt higher than in 2015 and 2016, respectively, mainly due to higher production in the Northern System. Blended volumes in Asia totaled 66.2 Mt in 2017, 48.1 Mt and 24.9 Mt higher than in 2015 and 2016, respectively. Sales volumes of iron ore and pellets reached 343.1 Mt in 2017, remaining practically in line with 2016, but with improvements in the portfolio mix. In 4Q17, some sales were deliberately postponed to 1Q18 for margin optimization purposes. On a quarterly basis, Vale’s 4Q17 iron ore production reached 93.4 Mt, 1.8% lower than in 3Q17 due to the seasonal weather conditions in the Southeastern and Southern Systems and 1.1% higher than in 4Q16 due to the S11D ramp-up in the Northern System which more than offset the reduction in lower grade ore production from the Southern and Southeastern Systems. Average Fe content was 64.3% in 4Q17, slightly higher than the 64.1% in 3Q17 mainly due to the S11D ramp-up and the reduction in lower grade ore production aligned with the ongoing strategy to maximize margin. Northern System The Northern System, which comprises Carajás, Serra Leste and S11D, achieved a production record of 46.7 Mt in 4Q17, 15.0% and 3.7% higher than in 3Q17 and 4Q16, respectively, mainly due to the ramp-up of S11D, which is advancing according to plan.

 8 VALE’S FINANCIAL REPORT 1Q15 Southeastern System The Southeastern System, which encompasses the Itabira, Minas Centrais and Mariana mining hubs, produced 26.0 Mt in 4Q17, 3.2% Mt lower than in 3Q17 mainly due to Vale’s actions to reduce supply of lower grade and high silica material, as well as weather-related seasonality and 6.3% lower Mt than in 4Q16 due to the curtailment of lower grade ores production. Southern System The Southern System, which encompasses the Paraopeba, Vargem Grande and Minas Itabirito mining hubs, produced 20.0 Mt in 4Q17, 11.2% lower than in 3Q17 mainly due to Vale’s actions to reduce supply of lower grade and high silica material, as well as weather-related seasonality and 14.6% lower than in 4Q16 due to the curtailment of lower grade ore production. Midwestern System The Midwestern System, which encompasses the Urucum and the Corumbá mines, produced 0.6 Mt in 4Q17, in line with 3Q17 and 4Q16.

 14 VALE’S FINANCIAL REPORT 1Q15 Canadian operations Production from the Sudbury mines reached 17,700 t in 4Q17, 4.3% lower than in 3Q17 and 11.1% lower than in 4Q16. The decrease compared to 3Q17 was due to the full transition to a single furnace operation in 4Q17 whereas Sudbury operated with two furnaces during part of 3Q17. Production decreased in relation to 4Q16 due to the transition to a single furnace operation as well as the cessation of mining activities at Stobie mine since 2Q17, following Vale’s strategy to optimize margins and reduce the nickel footprint. The ramp-up of the single furnace operation was completed ahead of schedule and the furnace has been running above expected levels. Production from the Thompson mines reached 7,000 t in 4Q17, 4.5% higher than in 3Q17 and 2.8% lower than 4Q16. The increase when compared to 3Q17 was due to a scheduled maintenance shutdown at its surface plants in 3Q17. The decrease when compared to 4Q16 was due to lower production as the Birchtree mine was placed under care and maintenance at the end of September, as well as the closure of one of the furnaces since January 2017 whereas Thompson operated with two furnaces in 4Q16. Thompson will fully transition to a mine-mill operation in 3Q18, when the remaining furnace and refinery will be shut down. Production from the Voisey’s Bay source reached 13,200 t in 4Q17, 26.9% higher than in 3Q17 and 19.0% lower than in 4Q16. The increase compared to 3Q17 was mainly due to the drawdown of Voisey’s Bay feed in Thompson as it returned to full production after the scheduled maintenance shutdown in 3Q17. Production decreased in relation to 4Q16 as both Thompson and Sudbury operated with two furnaces during 2016 and consumed higher volumes of Voisey’s Bay feed. Production at the Long Harbour processing plant reached 8,400 t in 4Q17, in line with 3Q17 and 61.5% higher than in 4Q16. Production continues to ramp up with November 2017 output reaching 85% of nameplate capacity. The nickel concentrate being produced at Voisey’s Bay is now processed solely at Long Harbour. Indonesian operation (PTVI) Production of finished nickel from PTVI reached 19,000 t in 4Q17, 4.4% higher than in 3Q17 and 12.8% lower than in 4Q16. The decrease compared to 4Q16 was mainly due to differences in the required time for processing matte into finished nickel as increasing volumes of PTVI source feed were shipped to our Clydach refinery. PTVI nickel in matte production reached 19,300 t in 4Q17, 4.5% lower than in 3Q17 and in line with 4Q16.

 15 VALE’S FINANCIAL REPORT 1Q15 New Caledonia operation (VNC) Production of finished products from VNC reached 10,900 t in 4Q17, 7.9% and 22.5% higher than in 3Q17 and 4Q16, respectively. Production of NiO and NHC at VNC reached 10,600 t in 4Q17 and an annual production of 37,300 t in 2017. Site production was 12.8% higher than 3Q17 and 14.0% higher than 4Q16. NiO represented 80% and NHC 20% of VNC’s 4Q17 site production. VNC continues to ramp up its production. Brazilian operation (Onça Puma) Production reached 6,000 t in 4Q17, 15.5% lower than in 3Q17 and 7.1% higher than in 4Q16. The decrease when compared to 3Q17 was due to lower ore grades while the increase when compared to 4Q16 was a result of stronger plant performance in 4Q17.

Production overview Copper production4 reached 438,500 t in 2017, remaining practically in line with 2016 and with the guidance of 438,000 t that had been previously announced. Production decrease in Canadian operations, mainly due to the flowsheet transition towards a smaller footprint as well as the impact of an unscheduled maintenance shutdown at the Coleman mine, was practically offset by a record annual production of 193,400 t at Salobo, 17,500 t higher than in 2016. Sales volumes of copper reached 423,800 t in 2017, remaining in line with 2016. Sales volumes are lower compared to production volumes due to payable copper vs. contained copper content: part of the copper contained in the concentrates is lost in the smelting and refining process and, hence, payable quantities of copper are approximately 3.5% lower than production volumes.

 17 VALE’S FINANCIAL REPORT 1Q15 Brazilian operations Production of copper in concentrate at Sossego totaled 22,600 t in 4Q17, 11.7% lower than in 3Q17 and in line with 4Q16. The decrease when compared to 3Q17 was due to lower ore grades being processed at the mill. Production of copper in concentrate at Salobo reached a quarterly record of 53,000 t in 4Q17, 2.3% and 6.4% higher than in 3Q17 and 4Q16, respectively, mainly due to higher feed grades and strong plant performance. Salobo achieved a monthly production record of 18,500 t of copper in concentrate in November. Canadian operations Production of copper from Sudbury reached 25,400 t in 4Q17, 15.6% and 21.1% lower than in 3Q17 and 4Q16, respectively, mainly due to the extended unscheduled maintenance at the Coleman mine as well as the cessation of mining activities at the Stobie mine since 2Q17. Production of copper from Voisey’s Bay reached 9,200 t in 4Q17, 39.4% higher than in 3Q17 due to the three week scheduled maintenance period in 3Q17. 4Q17 production was 16.4% lower than in 4Q16 due to lower copper mine grades and as a result of more Voisey’s Bay nickel concentrate feed being sent to Long Harbour rather than Sudbury in order to support Long Harbour’s successful ramp-up. In 2018, copper cathode production from Voisey’s Bay source feed will increase at Long Harbour.

The reconciliation of previous period volumes attributed a negative amount to T hompson and higher volumes to Voisey’s Bay in 4Q17 . Production overview Cobalt reached an annual production of 5,811 t in 2017. Cobalt production totaled 1,650 t in 4Q17, 10.8% and 3.1% higher than in 3Q17 and 4Q16, respectively, mainly driven by production from VNC, Voisey’s Bay and in Sudbury. Production of cobalt from Sudbury source takes about 3 months from the moment nickel ore is mined at Sudbury to the moment that the cobalt by-product is processed in Port Colborne. Sudbury source cobalt decreased 19.4% compared to 3Q17 mainly due to the impact of the closure of Stobie mine in 2Q17, whose inventory of cobalt intermediate was drawdown and processed in 3Q17. To compensate for this decrease, Sudbury cobalt production line consumed greater amounts of external cobalt feed, leading to the increase in cobalt from Other sources. Voisey’s Bay cobalt production increased compared to 3Q17, mainly due to the successful ramp-up of Long Harbour. As Long Harbour continues to ramp-up we will benefit from the high cobalt recoveries at Long Harbour and produce more Voisey’s Bay source cobalt than in previous periods. Also, there was a spot reconciliation of previous period volumes that attributed a negative amount to Thompson and higher volumes to Voisey’s Bay (254 t) in 4Q17. Cobalt production in Long Harbour increased from around 100 t in 1Q17 to 400 t in 4Q17, a significant increase that strengthens the refinery performance with robust by-product credits.

Coal production in 4Q17 was 2.6 Mt, 19.8% lower than in 3Q17. The lower quarterly production was mainly impacted by an already addressed failure in one of the hydraulic excavators, which is also the main reason for the lower production compared to the 11.7Mt forecast announced on Vale Day 2017. The 49% increase in production compared to 4Q16 is a result of the rampup of Moatize II, partially offset by the divestment of Carborough Downs mentioned above, whereas standalone production at Moatize increased 62.5% when compared to 4Q16. Production of metallurgical coal from Mozambique was 1.4 Mt in 4Q17, 23.4% lower than in 3Q17 and 41.0% higher than in 4Q16. Production of thermal coal was 1.2 Mt in 4Q17, 14.9% lower than 3Q17 but 100.0% higher than in 4Q16. The higher share of thermal coal in overall production in 4Q17 was due to a combination of the geological characteristics of the feed, with relatively higher ash content, and the processing of remaining tonnes of thermal coal stockpile in the Coal Handling and Processing Plant 1 (CHPP1). Our expectation is that the share of

 21 VALE’S FINANCIAL REPORT 1Q15 metallurgical coal in overall production will return to 60% - 65% with the access to feed with lower ash content and the implementation of improvements in the coal preparation processes in 2018. Coal sales volumes reached 11.780 Mt in 2017, 13.7% higher than in 2016, with metallurgical coal sales increasing 46.3% in 2017 whereas thermal coal sales decreased 15.7% in the same period. Thermal coal sales decrease was due to high level of sales in 2016, as the ramp-up of Nacala Logistics Corridor enabled to draw down accumulated inventories of thermal coal produced in 2015.
