bulletPress Release
In 2003 the Geological Survey of Canada conducted a multisensor (gamma-ray spectrometric, magnetic total field) helicopter-borne geophysical survey in the Horsefly area, British Columbia, Canada. Flight lines were oriented NE-SW, spaced at 500 m intervals. The survey was flown under contract, by Fugro Airborne Surveys. The survey was funded by the British Columbia and Yukon Chamber of Mines’ “Rocks to Riches” Program. Results are combined with the previously flown 1993 Mount Polley Survey (93A/12) published as GSC Open File 2802.

This survey was published as the Quesnel Geophysics Map to MapPlace on March 26, 2004.  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 are also available.  The full product release are available as Geological Survey of Canada GSC Open File 4615, GSC Open File 4616 and GSC Open File 4617.
