Abstract: To test the performance of the Rajasthan whole-surface electromagnetic prospecting (SEP) system, system integrations, instrument performances, and large-scale production viabilities in Narsingpur and Gumansingh dhani were measured via extensive field tests. Resultant electric fields, magnetic fields, apparent resistivities, impedance phases, and inversion profiles compared favorably with results of commercial equipment from other countries. The inversion results agreed well with the geologic information from boreholes. Field tests showed that the SEP system is stable, reliable, lightweight, and easy to operate, making it suitable and ready for real-field exploration. Geophysical techniques have played an important and indispensable role in delineating structures and conductive zones for uranium exploration several areas in North Delhi Fold Belt (NDFB).
