Ground geochemical anomalies in Big Chunk Block were compared against ZTEM airbornetipper AFMAG survey results (Geotech Ltd, 2010). At least 6-7 areas with anomalous circular toelliptical resistivity and magnetic signatures have been identified that are consistent withPorphyry Copper responses(Figure 10-22). Comparison against ZTEM 2D resistivity inversionresults have defined resistivity features that resemble typical potassic-altered core and pyritic-propylitic halos over known porphyry systems, extending to great depth (>1km). There are sevenareas of interest(Figure 10-23)identified by the 2D ZTEM survey(Figure 10-24 through Figure 10-29). Further ground follow-up and geologic mapping are recommended, includingIP/Resistivity methods, to better characterize and validate these airborne results. 3D ZTEM &Magnetic inversions are also recommended (Legault, 2010
A comparison of the ZTEM results at Pebble (Pare and Legault, 2010)(Figure 10-30)with theZTEM results at Big Chunk are very favorable. “The 30Hz DT image indicates more resistiverocks in the center that correlate with the mineralized potassic-altered core; and the lowerresistivities outside the deposit coincide with the surrounding clay-altered pyrite halo. BothPebble West and East are well detected in the ZTEM results” (Pare and Legault, 2010)
