Bonnifield Mining District Geophysical Survey

The Bonnifield electromagnetic and magnetic airborne geophysical survey data were acquired in 2006 and 2007 with a DIGHEM-V Electromagnetic (EM) system and a cesium magnetometer. Aeromagnetic and electromagnetic data were acquired for 613 sq miles during the helicopter-based survey. These new data were combined with a geophysical survey of the Liberty Bell area released in 2002 by DGGS. The merged grids and maps are included in this dataset.
