UNIQUE INTEGRATED LOGISTICS

Since Iron ore is a bulk commodity, an integrated logistic (mine ����railway ���� port) is the key factor for a successful operation

Mine SuperportRailway

Serra Azul unit is near to theMRS railway - 10 km from themine, a distance currentlytraversed by trucks.

MMX has a long term contractwith MRS railway, which connectsthe mine with the CSN’s Itaguaíport and to the SudesteSuperport.

Sudeste Superport is located inItaguaí and will have 50Mtpy ironore shipping capacity. The Superportwill have a depth of 20 meters,enough to handle Capesize vessels.

Offtakers (Shareholders)

Long-Term contract (20 years) to trade ironore. SK will take-off part of the SudesteSystem yearly production equivalent to itsparticipation in MMX Capital (14%).

SK and Wisco will togetherofftake 64% of total production

Long-Term contract (20 years). Wisco willoff-take at least 50% of MMX Sudesteproduction.
