Open-pit Ni mine.
Saprolite (originated due to weathering of serpentinites) overlain by laterites and extending for 35 km in an arc-shaped area from southwest to northeast. The deposit, discovered in 1960, is located in the Barro Alto mafic-ultramafic complex, part of the Pre-Cambrian shield in the state of Goiás.
