ERL 150, ERL 151 and ERL 152 Second Annual Report 20 May 2000 to 19 May 2001

Abstract

The report discusses exploration activities during the second year of tenure. Geophysical surveys conducted within ERL 150 identified resisitivity and phase anomalies. Drill testing one of the geophysical anomalies was planned, but was postponed for the next year. A gravity survey within ERL 151 highlighted anomalous areas that were tested with a number of drill holes. Drilling confirmed the presence of prospective mineralisation, alteration and lithologies. No exploration was conducted within ERL 152 during the reporting period. A narrow zone of primary pitchblende mineralisation was intersected at 250.5m by drill hole N147-9. Wider anomalous zones of radioactivity are scattered through the reminder of the basement, between 200m and 260m. Minor anomalous radioactivity was detected in the sandstone between 28 and 68m, correlating with elevated Th values detected in the geochemical analysis. Elevated Th and U values were also present in the chlorite-altered sandstone immediately above the unconformity. A minor radiometric anomaly occurs at 152.7m, and is associated with moderately chlorite altered mica shist in drill hole N147-10. In drill hole N147-13 minor radioactivity was detected in the sandstone between approximately 52 and 60m, corresponding to elevated Th values over a similar interval. Anomalous radioactivity was not detected in the basement. The presence of WNW and NW trending structures parallel to the Nabarlek structure was further confirmed by both the gravity survey and drilling. The WNW trending gravity low demands further testing and are considered prospective due to the confirmation of reverse structures and unconformity.
