1st priority are any and all coincident EM and Mag anomalies anywhere remotely on strike from DE1 and DE2, using the airborne Mag for guidance. 2nd priority, the west side of any Mag anomalies in the same area. The latter presumes that accumulations of Ni/Cu sulphides will occur in the basal portions of any ultramafic/mafic bodies, whether volcanic or intrusive, and that "tops" are to the east.
