Very low frequency electromagnetic method was carried out at twenty three (23) locations within Parts of the Eastern Basement Complex of Nigeria. The field data were collected using ABEM Wadi VLF (very low frequency) electromagnetic instrument with other accessories. A transmitter located at Cutler, Maine USA, designated as NAA with 24.0 KHz frequency and 1000Kw transmission power was used throughout the data collection exercise. The profiles were of lengths between 120m and 650m. The station

The results of the study showed that majority of the fractures were oriented in the NE -SW direction, followed by fractures oriented in the NW -SE direction indicating that the study area is well fractured and has good potentials for ground water.
