An airborne ElectroMagnetic (EM) survey system wherein the system includes; first, a series of transmitter coils, which induce a primary (EM) field into the earth resulting in a secondary EM field being created in any sub-surface electrically conductive bodies; and second, a set of three orthogonal receiver coils which detect the secondary EM field. Multiple transmitter coils through which an electric current is pumped, form part of the structural, aluminum framework of a multi-rotor drone. The receiver sensor may be an EM induction sensor, comprised of multi-turn, copper windings, mounted inside an aerodynamic bird and separated by non-conductive sphalerite, which acts as an electrical insulator to limit self-induction and capacitance. Additionally a lighter-than-air balloon may be used to add vertical lift and increase a pendulum effect.
