In 2003 the Imperial Metals Corporation conducted a multisensor (gamma-ray spectrometric, magnetic total field) helicopter-borne geophysical survey over the Mount Polley Mine area, British Columbia, Canada. Flight lines were oriented NE-SW, spaced at 100 m intervals. The survey was flown under contract, by Fugro Airborne Surveys. Results are available in a variety of digital and printed formats at 1:20 000 scale. The survey was funded by the British Columbia and Yukon Chamber of Mines' "Rocks to Riches" Program and by Imperial Metals Corporation

The results are available as follows:
