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. Results are available in a variety of digital and printed formats at 1:50 000 scale and are combined with the previously flown 1993 Mount Polley Survey results (Open File 2802, 93A/12) at 1:250 000 scale. The 2003 Horsefly survey was funded by the British Columbia and Yukon Chamber of Mines' "Rocks to Riches" Program.
The results are available as follows:
