 The Emily Ann orebody was unequivocally discovered by geophysical surveying, the result of a flatter orientation of the orebody, the fact it is hosted within conductively dead felsic gneiss, and the depth of the upper parts of the orebody reaching to within 200m of the surface.The Emily Ann discovery was a technical triumph, because it is a mechanically displaced recumbent fold of sheared massive sulfide hosted several hundred metres off the original ultramafic-felsic contact in a position not generally expected to host nickel sulfides.The Maggie Hays and Emily Ann orebodies are hosted within a komatiitic belt of rocks within the Archaean c. 2.85 Ga Lake Johnston Greenstone Belt (LJGB).
