| Details: A high-resolution aeromagnetic and airborne gamma-ray spectrometric geophysical survey in the Bonaparte Lake area (parts of NTS 92P and 093A) was completed in 2006. Funding for the survey was provided by Geoscience BC, Natural Resources Canada’s Targeted Geoscience Initiative (TGI3), Candorado Operating Company Ltd., GWR Resources Inc. and Amarc Resources Ltd. Project management was undertaken by the Geological Survey of Canada. The western portion of the survey area was surveyed with a fixed-wing by Sander Geophysics Ltd., while the eastern portion was surveyed with a helicopter by Fugro Airborne Surveys. This map, in UTM Zone 10 projection, features 2 magnetic parameters, residual total magnetic field and first vertical derivative of the magnetic field, and multisensor gamma ray spectrometric geophysical data.
The files are available for download in various formats. Details of the aeromagnetic survey can be found in the Fieldwork 2006 article by Miles, W.F., Shives, R.B.K., Carson, J., Buckle, J., Dumont, R. and Coyle, M: Airborne Gamma-Ray Spectrometric and Magnetic Surveys over the Bonaparte Lake Area (NTS 092P), South-Central British Columbia (PDF document, 208 Kb).

A joint publication of seventeen 1:50,000 total field magnetic anomaly and vertical derivative maps (GSC Open Files 5488-5500 and Geoscience BC Maps 2007-3-1 to 3-9 and 2007-4-1 to 4-8) were released on April 3, 2007, to coincide with the Kamloops Exploration Group KEG conference. Each open file consists of 10 maps.
