In the Gandarela Mountain Range, located in the Metropolitan Region of Belo Horizonte (Minas Gerais), Vale aims to produce 24 million tons of iron ore per year, for 17 years. Vale’s project is called Apolo Mine. Gandarela presents the largest and best preserved metallophile savannah (canga ecosystem) of the Iron Quadrangle (the mining region of Minas Gerais). This type of savannah has few remnants in Brazil, as it is generally destroyed by mining. It is an important recharge area for aquifers and, therefore, coincides with great underground water potential, which is important for the formation of river springs and also directed used for public water supply. For this reason, environmentalists even created the term Aquifer Quadrangle to oppose the official name Iron Quadrangle and thus the idea of a regional vocation focused on mining. It is estimated that 80% of the 5 billion m3 reserve of this Aquifer are located under the metallophile savannahs and that 40% of the remaining savannahs in the region are in Gandarela Mountain Range. Therefore, Apollo Mine could damage not only unique attributes of savannah ecosystems, such as the endemic biodiversity and dozens of caves, as well as the availability of water for the Metropolitan Region of Belo Horizonte [1, 2, 4].
