The Ladue electromagnetic and magnetic airborne geophysical survey is located in eastern Alaska in the Fortymile mining district, about 325 kilometers southeast of Fairbanks. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system in August 2010. A total of 5471.1 line kilometers were collected covering 1928.9 square kilometers. Line spacing was 400 meters (m). Data were collected 30 m above the ground surface from a helicopter towed sensor platform ('bird') on a 30 m long line. The survey data were aquired and/or processed by Fugro Airborne Surveys Corp. and Fugro GeoServices, Inc. and administered by the Alaska Geological & Geophysical Surveys (DGGS).
