Ann: Follow Up CopperGold Exploration at Nankivel Porphyry Target-IVR.AX, page-4

This is really shaping up to be one hell of a deposit?

A number of new geological and geophysical clues were behind the definition of the Nankivel and Helen porphyry copper targets.
Of particular note, the airborne magnetic data (Figure 2) shows a magnetically-depleted target area extending 1.5km west from the recent Nankivel drill hole. This magnetic pattern is interpreted to reflect porphyry alteration of the earlier magnetic granodiorite within the 2.5km by 5km intrusive complex. The geology and visible low-level copper sulphide mineralisation intersected in PPDH147 is also a vector because it is consistent with the margin of the porphyry target.
PPDH147 was targeted at a magnetic high, which is now explained by magnetite (magnetic iron oxide) plus pyrrhotite (magnetic iron sulphide) intersected at the lower depths of the hole.
Similar zones of high magnetics abut the new Nankivel porphyry target area (Figures 2 & 3). These may be skarn mineralisation formed in carbonate-rich rocks. Skarn-hosted copper deposits are frequently found on the margins of porphyry copper systems.
Drilling by Investigator in 2014 had already proved the anticipated presence of copper and gold mineralisation in the Paris field with the intersection of copper-gold-silver in the Helen skarn at the northern end of the intrusive complex (Figure 3). The Helen skarn is now interpreted to be on the margin of the second magnetically-depleted zone of similar size to the Nankivel porphyry copper target. Although drilling suggests the Helen skarn is small, it is significant support for the newly identified and large Helen porphyry target area.
The Nankivel and Helen porphyry targets are also enhanced by interconnection with the Paris silver deposit by mineralising structures and rhyolite dykes (Figure 3).

This is all FANTASTIC NEWS!!!
