When conducting electrical exploration onshore aimed at studying deep ore objects, traditional electrical exploration methods are usually used. Geophysicists most often use modifications of the TEM methods or methods aimed at studying the polarization of the environment. Both approaches have a number of disadvantages when working on deep objects. The polarizability of deep objects has little effect on the signals measured at the surface. And the TEM methods provide very poor information about 3D objects. To overcomethese problems, it is necessary to use methods that are much more sensitive to three-dimensional disturbances, namely, such are the ore deposits in relation to the host environment. The most logical way out seems to be the use of methods based on vertical currents, for example, the VECS method. It is this approach that makes it possible to identify ore objects at great depths overlain by various rocks.
