Miguel Burnier is a mid-sized iron ore surface mine situated in Brazil's Quadrilátero Ferrífero (QF) region, approximately 85 kilometres south of the city of Belo Horizonte. Miguel Burnier's mining operations were closed at the end of 2015 due to weak iron ore and steel market conditions. Though the mine's processing facilities are still operational handling ore trucked from Varzea do Lopes. As Gerdau does not have any short-term plans to resume operations at Miguel Burnier, we have assumed it will remain permanently idled. Miguel Burnier used to produce a concentrate product that was either used at Gerdau's nearby Ouro Branco steel facility or sold into the seaborne export market.
