The helicopter circles over a range of verdant mountains in the Carajás National Forest, a park in Brazil’s Amazonian state of Pará.
In spite of the thick jungle on their lower slopes, some of the peaks are strangely bare. This is a clue as to what lies below the surface – a giant iron ore body known by miners as Carajás Serra Sul S11D, which decodes as Carajás southern mountain range iron ore body 11, block D.
The discovery is so large it will boost the production of Brazilian miner Vale, the world’s second-largest iron ore miner by volume, by nearly a third after it comes on-stream in 2016 compared with the company’s expected production this year of 312m tonnes. Vale claims it is the largest such project in the iron ore industry.
“We are flying above the S11D,” says Jamil Sebe, Vale’s director of northern region ferrous metal projects, above the noise of the helicopter rotors. “Where you have iron, you don’t get trees, that’s one of the ways to discover iron ore.”
Conceived during the commodity supercycle of the past decade, the $20bn project to develop S11D comes as the environment for the industry is changing radically.
Iron ore prices in May suffered their sixth monthly consecutive drop, marking a record losing streak for the steelmaking ingredient.
