Notes

Fugro, Inc. performed an airborne geophysical survey using the DIGHEM (Digital Helicopter ElectroMagnetics) aircraft over a 937 km^2 survey grid. Airborne gamma radiation survey indicated anomalously high concentrations of U and Th correlated with highly evolved granite outcrops in the northern and eastern areas of the Chena Pluton. These measurements contributed to the geological map compiled.
