A high-resolution aeromagnetic survey was flown over a large area in northern Manitoba covering the northern extent of the Superior Boundary Zone in the Assean Lake area. This current survey, consisting of 29 400 line-kilometres of traverse and control lines, was monitored by the GSC and carried out by Goldak Exploration Ltd. of Saskatoon, Saskatchewan. Normal line spacing was 400 m for the traverses and 2400 m for the control lines, all flown according to a draped surface at a nominal ground clearance of 150 m.

This aeromagnetic survey and the production of these maps were funded by Natural Resources Canada's Targeted Geoscience Initiative (TGI) 2003–2005 and by Manitoba Industry, Economic Development and Mines. The maps were produced as part of the Trans-Hudson / Superior Margin Metallotect project as a contribution to the Northern Resources Development program of the Earth Sciences Sector, Natural Resources Canada.
