QUEST-West: Report on a helicopter-borne AeroTEM system electromagnetic & magnetic survey
by Aeroquest Surveys

Report Components

Note: This survey consists of two blocks (Block 1 in UTM Zone 9 and Block 2 in UTM Zone 10), which are subdivided into smaller blocks. Six infill blocks were also flown over known mineralization. Map below shows the QUEST-West survey blocks and the 6 infill survey blocks. Click on the map for a larger view.

(Projection: Mercator, WGS 1984)

The geophysical profile data is archived in a Geosoft GDB binary format database. A description of the contents of the individual channels can be found in the PDF report (below). The Geosoft free viewer can be downloaded from here.

    Report Description
    Geoscience BC Report 2009-6 is part of the QUEST-West project, which covers over 40,000 square kilometers from Vanderhoof and Fort St. James to Terrace and Kitimat. The Regional District of Bulkley-Nechako, Northern Development Initiative Trust and the BC Geological Survey (Ministry of Energy, Mines and Petroleum Resources) partner with Geoscience BC on this project. This data release is on the airborne electromagnetic (EM) survey of QUEST-West area collected by Aeroquest Surveys.
