New data on the structure, formation and prospecting signs of the ore.controlling structures of the Novye Peski gold.sulphide occurrence (Archean Vedlozero.Segozero greenstone belt, Shotozero prospect) are reported. Spatially discrete NE. and dominantly near.N.S. trending steeply dipping shear zones of varying size, closely.spaced (echelon.like) in some parts of the study area, are identified as these structures. Sulphide mineralization is emplaced in these zones. The geophysical study of the gold occurrence shows that the resistance electrotomography and induced polarization methods can and should be used to reveal ore.controlling structures in bedrock covered by Quaternary deposits. The method tested can be employed to reveal shear zones by local low.resistance anomalies triggered by the elevated fracturing and inundation of rocks in intense deformation zones; to draw conclusions on the occurrence of ore components in the zones on the basis of analysis of the induced polarization parameter distribution; and to geometrize a geophysically anomalous prospect by interpreting geoelectrical sections.
