[en] Forty-two uranium and mixed uranium and thorium anomalies were selected from the analogue radiometric records generated during theBarberton-Phalaborwa airborne geophysical survey. Thirty-eight of the anomalies plotted over rocks of the Timeball Hill and Daspoort Formations, and ground follow-up work is recommended for these anomalies. Two more anomalies probably originate from rocks of the Palabora Igneous Complex, another anomaly overlies a diabase intrusive, and the remaining anomaly appears related to an outlier of Ecca Group rocks
