The advent of graphene technology has highlighted the importance of graphite in the modern industrial landscape, making this mineral strategic. The new fields of its use have made the exploitation of flake graphite economically attractive. The kinzigitic gneisses of the Jequitinhonha Complex contain graphite mineralizations and have been the object of recent studies. Understanding the behavior of mineralization, through characterization, allows advancement in the techniques for its exploration and exploration. Establishing the influence of the contaminants from the geological environment and the features they impart to the mineralization is important in order to standardize prospecting and processing procedures. This study allowed determining the orebodies resistive/conductive patterns as a function of petrological contaminants, defining the inherent characteristics of the graphite mineralization that make possible the standardization of the prospecting criteria and later the industrial use of the ore.
