18th century mine opened.


Ouro Prêto sits right on an outcrop of banded iron formation. This formation is a sedimentary rock with many layers of iron ore, often altered to iron oxide especially ochre. There are also copper deposits, which sometimes are transformed to malachite. The dark rocks were the reason for its name Ouro Prêto which means black gold as a reference to the dark colour of the local gold, which contains a lot of iron oxides. However, the gold is mostly bound to gold bearing quartz veins, not to the iron.


Mina 13 de Maio (May 13th Mine) is named after the road where it is located. The mine entrance offers a spectacular view of the Church of Santa Efigênia, Pico do Itacolomi and the Historic Center. The mall exhibition at the entrance shows mining tools and other iron artifacts. It is located in the Casa da Mineração, which also has a small beer bar and a local handicraft shop.
