NATURAL RESOURCES AND REWEABLE ENERGY DENILSON RODRIGUES DE ARAUJO, Dr. Ing., M.Sc. GENERAL MANAGEMENT - TECHNOLOGY AND ECO-EFFICIENCY NATURAL RESOURCES AND REWEABLE ENERGY SOME SAMARCO’S EXPERIENCES AND CHALLENGES PORTO ALEGRE, 31 AUGUST 2015

Since 1977 producing and supplying iron ore pellets to seaborne market WHO WE ARE SAMARCO Since 1977 producing and supplying iron ore pellets to seaborne market Total Pellet Production = 501 million ton (E) Seaborne Market = 114.8 million ton (2014)  22,8% Samarco Market Share = 25 million (2014)  21%

SAMARCO AND IRON ORE PELLET MARKET 2nd largest iron ore pellet supplier in seaborne market 114.8 M Ton

INNOVATION CHALLENGE IN SAMARCO TO IMPLEMENT TECHNOLOGICAL SOLUTION FROM MINE TO PORT A company where technology is applied intensively to optimize the use of natural resources and generating economic and social development, with respect for the environment. Mining Concentration Pipeline Pelletizing Port Iron Ore Concentrate (67 – 68%%Fe) Poor Iron Ore (45%Fe) Iron Ore Pellets (66 – 68%%Fe)

SAMARCO COMPETITIVENESS one of the lowest operating costs COMPARED TO IRON ORE PRODUCERS A company currently running at one of the lowest operating costs when compared to other iron ore producers due to: optimized mining operations (open pit); logistics advantages: pipelines system and own port terminal. management highly focused on operating efficient; technological innovative efforts.

SAMARCO SUSTAINABILITY MODEL: INNOVATION & TECHNOLOGY– AN IMPORTANT PILAR

WATER SPECIFIC CONSUMPTION (m3/ton IRON ORE) WATER RESOURCES AND MINING SECTOR WATER SPECIFIC CONSUMPTION BY IRON ORE PRODUCER COUNTRY IRON ORE PRODUCTION (E) WATER SPECIFIC CONSUMPTION (m3/ton IRON ORE) TOP 5 IRON ORE PRODUCER COUNTRIES > 100 million tons/year < 100 million tons/year SAMARCO (with pipeline system) Source: BI Samarco Source: Adapted from Bluefield Research, CRU and Samarco

ENERGY EFFICIENCY AT PELLETIZING FURNACES COMPARISON TO OTHER PELLETING OPERATIONS

GHG EMISSION PERFORMANCE CARBON INVENTORY 10 -15% -55% SOURCE: SAMARCO MAIN ACTIONS: 2008: 3rd pellet plant startup  2014: 4th pellet plant startup. 2010: Natural gas replacing heavy fuel oil; Gains from LSS projects and other developments SOURCE: IBRAM

Heat Generation (Biocombustion) EXAMPLE OF TECHNOLOGICAL STUDIES IN PROGRESS ALTERNATIVE RENEWABLE ENERGY GENERATION AND USAGE Technological solution: Conversion of Biomass into Renewable Thermal Energy to Pelletizing Furnace Where: pelletizing furnace replacing natural gas/heavy fuel oil and/or even ground antracite /pet coke added into green pellets. Benefits: Renewable energy utilization (even less GHG) to provide a valuable destination any wood-based solid wastes; Eucalyptus PELLETING FURNACE(S) Other sort of biomass Pre-processing Heat Generation (Biocombustion)
