The gold bearing mineral from Bundelkhand region neighbouring district Lalitpur develops good dc as well as magneto-conductivity under radio frequency excitation. The granitoid crystals G-4 & G-6 well get in four probe Hall geometry to record the ohmic as well as magneto potentials under radio frequency (2-5.2 MHz) excitation and magnetic field 4, 6 KGauss has been studied and their electrical carrier concentrations ‘n’ with 5 MHz and magnetic field, H=14 KGauss had been computed. The MRF excitation in Geo-Rock crystals seems to impose semiconductor synthesis, since electrical carrier concentration ‘n’ comes out to be of the order of 10 14 per cc.
