[en] The results of a high-sensitivity aerial gamma-ray spectrometer and magnetometer survey of the Circle Quadrangle, Alaska, are presented. Instrumentation and methods are described in Volume 1 of this final report. Statistical and geological analysis of the radiometric data revealed two uranium anomalies worthy of field checking as possible prospects. One is located over Mesozoic granite which is believed to have the best potential for future economic uranium deposits in either vein deposits or porphyry-type uraniferous late-stage differentiates. Another particularly strong uranium anomaly is associated with Circle Hot Springs, and is thought to be attributable to radium-rich hot-spring deposits which may be taken to indicate potential for uranium mineralization in that region
