This paper presents some results of HTEM (Helicopter Transient Electromagnetic) and magnetometry geophysical modeling/inversion and their integration with radiometric data in the Quadrilátero Ferrífero area, MG, Brazil. The HTEM survey identified 898 conductors, with many of them close to mineralized gold zones and strongly correlated to structural and geophysical lineaments, which could indicate the structural control of sufidation zones. The geophysical modeling was focused on two areas: the Lamego and Roça Grande gold deposits. The results showed that the conductors main dip direction towards to SE and seems to indicate the structural configuration of the mineralized bodies with their enclosing rock.
