Setting Net Lake is about 195 km north of Red Lake, the closest road terminus, and is accessible only by float or ski-equipped aircraft.This field project was designed mainly to test the use of surface geochemical and biogeochemical exploration methods in an area of widespread, low-grade Precambrian molybdenite-pyrite-chalcopyrite mineralization covered by extensive transported Quaternary overburden, including variable thicknesses of boulder till and Late Pleistocene lake clay. The report describes the location and access of the area and the scope and purpose of the geochemical survey; the geology of the area; geochemical methods used; and the results obtained.
