General Discussion, page-820

The kmz file in ( post ) contains a Web Page reference, and geophysical maps for 'Kperc Radiometry' and 'IP Chargeability'. There are two areas of high IP Chargeability (pink) in the IP Chargeability map. Those areas were overlaid onto the Kperc map (green/black) and shown in the map above.
.

The black and pink areas appear to be paired. In each pair the pink area is on the SE margin of the black area, and each pair is of proportionate size and shape. The referenced Web Page is an interesting read and, when drill cores are assayed, may explain the implications of these pairings.
.

The Kperc measurements are surficial. They increase in salt pans (Lake Mackay ~ 1.2%) and are almost zero in dunes. In the West Arunta there are only a few high Kperc areas (4.5% in K-Granites), and all are located in an E-W arc 200 km long. The largest area comparable to Pokali, and at half its size, is at (-23.131, 128.705).
.

It is 42km ESE in RCR tenement 'E 80/6013'.
The 'IP Chargeability' found in that tenement will also be interesting.
