The best geophysical method for identification of Iron ore deposit is ground magnetic survey as hematite and Magnetite have ferro-magnetic properties. Ground magnetic surveys were carried out with 50m traverse interval and there is no station interval because the instrument which we used is a continuous recorder (sampling rate 0.5sec/reading).
