3D IPI'm still trying to get a read on why the large Ridge Target Area is relatively conductive. I say relative, because there is no legend showing what the conductivity numbers are on the colour contours. If we assume that the logged core of CA-21-15 shows diorite/gabbro, mafic volcanics, ultramafic basalt, ultramafic komatiite and syenite porphyry, then what would be the conductive material in these rocks, that would give such a large chargeability response as indicated on the map. The latter is a wide spread conductor, suggesting a rather large body of conductive material, as opposed to a narrow one. Was there lots of either sulphides, graphite or magnetite in the core? I suggest that most of the chargeability response may be related to serpentinization of the magnesium-rich ultramafic portions of the mafic volcanics (komatiites). The chargeability responses related to CA-21-15 (Zone L) and Zone G may be related to separate sources, and related to the diorite/gabbro. Just my thoughts.
