%X In the application of electroprospecting for mineral exploration, there are few clearly observed trends based on the development of electroprospecting technologies, hardware, software and computer technologies aimed at: a) the increase of electroprospecting application in comparison with other EM methods; b) application of electroprospecting at all stages of the exploration cycle; c) the increase of application of induction electroprospecting methods and, first of all, these which are based on the study of the natural EM field of the Earth (NEMFE). A special role here is played by the method of Broadband Magnetovariational Profiling (BMVP). Three stages in the application of electroprospecting are quite clearly distinguished: a) exploration for new mining provinces according to the distribution of resistivity in the Earth's crust and upper mantle (the AusLAMP project, a revolutionary idea proposed by Australian scientists; deep MT, scale 1 : 5,000 000 &#x2013; 1 : 1,000 000); b) exploration for large conductive ore bodies, areas with a prospecting survey square area of more than 100 km2 by airborne geophysics, for areas with smaller size - 5-component AMT on a scale of 1 : 200,000 &#x2013; 1 : 50,000; c) detailization and support of drilling operations, mapping of veins and dikes - 5-component AMT on the scale 1 : 20,000 &#x2013; 1 : 5,000 in complex areas with induction and geometric soundings using control source if Induced Polarization is an exploration factor.
