The survey is adjacent to the Richardson geophysical survey. Frequency domain electromagnetic and magnetic data were collected with the DIGHEMV system from September to November 2005. A total of 1758.4 line kilometers were collected covering 629.0 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.
