The objective of the study was to de- termine signatures of Pb from uranium ore mineralisation, identify as to the Pb present is geogenic and/ or antrogenic and provided an estimate of the age of the uranium ore mineralisation from measured Pb isotope. A total of 24 samples of uranium ore were collected from three mines and the lead isotopic ratios and age estimation signatures of the uranium ore mineralisation determined. Inductively Coupled Plasma Mass Spectrometer was employed for sample analysis. 206 Pb was abundant in the ore samples and was determined to be geogenic and not anthropogenic. The estimated age of the uranium ore mineralisation was in the range documented for the Namibian Damara Orogen. The studied showed that lead isotopic ratios can provide an estimate of the age of the uranium ore mineralisation and aid as a fool in nuclear forensics.
