IGO Core Geophysics Collaboration Final Report Eastern Contact Airborne Electromagnetic Survey Lake Mackay Project

Abstract

This Collaboration program was a SPECTREM 25Hz Airborne Electromagnetic Survey covering the contact between the Lander Rock Formation and the Andrew Young Igneous Complex to the east of the Grapple and Bumblebee Au-Ag-Cu-Pb-Zn-Co prospects. These prospects are associated with pyrrhotite and produce conductors that are detectable using airborne electromagnetics. The survey commenced on the 4 June, 2018 and was completed on 13 June 2018. The objective of this survey was to detect conductors that could be derived from 'Grapple Style' mineralisation and further define areas that could be amenable to soil sampling techniques. This has been successfully achieved with the program identifying late time conductors which are indicative of massive sulphides. Additionally, the depth of regolith derived from this survey has defined areas in which soil sampling will be an effective test for mineralisation that may not have a conductive signature.
