Helicopter Airborne Electromagnetics at 12.5 Hz - Western Australia Case studies

Low base frequency EM provides an advantage to detection of very conductive targets or for exploration with thick conductive cover. A comparison of a 30 Hz and 7.5 Hz system showed significantly better detection to a conductive body at 400 m depth. 12.5 Hz survey was acquired for a graphite exploration survey, providing better definition of a known mineralization zone and identifying areas with further mineralization potential. The AEM data agreed with depths to mineralization from drilling.
