The Minerals Division of the Minnesota Department of Natural Resources, having the responsibility of assessing the mineral potential of state controlled lands, felt this area required further evaluation. The state controlled land in this area is extensive. Therefore, geophysical and geochemical surveys were conducted in 1975 and 1976 for the objectives of identifying geophysical conductors and geochemical trends which may reflect economic mineralization. The purpose of these surveys was to produce a reconnaissance type assessment of the mineral potential of the area.
The geophysical and geochemical surveys described in this report are generally reconnaissance in scope. The geophysical surveys (EM and magnetics) were conducted on portions of the grid established for the above described drilling, and extended outward from this grid. The geochemical surveys consisted of lake sediment, organic stream bank, surface soil and peat sampling.
The geophysical data for this report was derived by Minerals Division field surveys and from open file lease information supplied by exploration companies.
