Abstract: | Analysis of airborne radiometrics highlighted several magnetic anomalies, possibly indicative of kimberlitic diatremes. There were no radiometric anomalies which warranted follow up. 7 of the magnetic anomalies were followed up on the ground by geochemical sampling. The results from which were negative for kimberlitic indicator minerals. This result significantly downgrades the potential for kimberlitic diatremes in the area. A grid was established over a prominent curvilinear magnetic anomaly in the NW of the licence. A scintillometer survey over this area produced low readings. The ground magnetic survey in this area showed the source of the anomaly to be 25 to 200m down and vary in thickness from 80-300m. Interpretation suggests an asymmetric fold. |
