In 2004 the Geological Survey of Canada conducted a multisensor (gamma-ray spectrometric, magnetic total field) helicopter-borne geophysical survey in the Mount Sylvester area, approximately due west of MacKenzie, British Columbia, Canada. Flight lines were oriented E-W, spaced at 500 m intervals. The survey was flown under contract by Fugro Airborne Surveys. Funding was provided by the British Columbia and Yukon Chamber of Mines Rocks to Riches Program, under a project submitted by the District of MacKenzie. Support for the Geological Survey of Canada’s Radiation Geophysics Section, acting as the Scientific Authority for the survey, was provided under Natural Resources Canada – Earth Sciences Sector’s Northern Resources Development Program. This survey covers rocks of the Quesnel Terrane, a belt prospective for bulk tonnage copper-gold deposits similar to the well-known Mount Milligan deposit.


This data was published with the Mount Milligan Geophysics Map to MapPlace as this Open File on April 8, 2005. The MapPlace data includes digital gridded images for 2 magnetic and 7 radiometric parameters for each survey area. The downloadable files from this website are in georeferenced TIF – tagged image and PNG formats (UTM NAD 83 and Albers projections) and GRD - Geosoft gridded data format (UTM Nad 83 only). PDF theme files area also available.  A full product release (in late spring 2005) will be made by the Geological Survey of Canada as a series of Open Files, including printed colour maps, images of the printed maps in PDF format, and digital line and grid data.


All publications of the BC Geological Survey are available digitally, free of charge, from this website.
