A gold mine owned by Mineracao Morro Velho, a subsidiary of Anglo American Corporation. The mine was started in 1910 and was still under maintenance in 2001. From 1982 until 1999, it produced about 22 tons of gold. Located about 40 km southeast of Belo Horizonte and about 5 km northeast of the Morro Velho mine.

The deposit is hosted by a banded iron formation (BIF) which is overlain by quartz-carbonate-sericite schists and underlain by chlorite-carbonate-quartz-talc schists. The BIF includes oxide-, silicate-, carbonate- and sulphide-facies rocks; most of the gold production came from the carbonate-bearing unit.
