Abstract
The aero-radiometric' survey map of Lere (sheet 147) was studied with a view to selecting an area for detailed ground investigation to determine the radioelement potentials of the region. The map revealed several anomalies out of which the one with high uranium count, low potassium count and zero magnetic intensity occuring on flight line 32 was choosen for further ground investigation. The ground spectrometric investigation was aimed at characterising the anomaly in terms of its radioelements content ie uranium, thorium and potassium. The investigation was particularly conducted to determine the uranium potentials of the anomalies detected in the region. Data was collected using a DISA-300 gamma ray spectrometer at stations spaced 50m apart. Analysis of data indicated that about 30% of the surveyed area could be characterised as an area of possible uranium mineralization. Available data from uranium geochemistry was compared with the equivalent uranium concentrations calculated from the field gamma-ray spectrometric data. The comparison showed that the uranium concentrations in the area may be of low grade. Thus an independent geochemical analysis of the rock samples in the area need be carried out.
