Jan 28, 2017 (A Wilson) - A background count of 20 cps was obtained. Calcite veins were analmalous with values around 30 cps indicating that this technique is useful as a prospecting tool (tighter spacings might useful in some areas where prospecting for calcite veins. This usefulness was further backed up when two new (previously undiscovered veins were found during the radiometric survey before any data was processed. There were some anomalous values obtained (80.1, 41.6, 53.6 and some very low values )which should be investigated
