Groundfloor Electromagnetics (GFEM) is a methodology that utilizes an airborne EM transmitter with a set off surface-based receivers. The larger transmitter-receiver separation in Groundfloor EM over standard airborne techniques yields the ability to compute the step-response with sufficient accuracy to study extremely high conductivity targets that are commonly encountered in nickel sulfide exploration. This technique adds a substantial improvement in conductivity discrimination, model stability, and data confirmation to an existing airborne EMM survey for a relatively little added cost. In the future, this technique should be considered as a best practice for massive sulphide exploration.
