The MapPlace - Bonaparte Lake
Geophysical Survey NTS 92P and 93A
(GBC Maps 2007-3-1 to 9 and 2006-4-1 to 8 / GSC OF 5488 - 5504) |
 |
| 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

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.

Additionally, the digital
profile and gridded data are available on-line and at no cost via the Geoscience Data Repository for
Aeromagnetic Data.

An interpretation of the aeromagnetic
data by Geological Survey of Canada was undertaken and the
findings reported at KEG 2007. |
Digital profile and gridded data, as well as
associated maps in .pdf format, area available for download free of charge
from Natural Resource Canada's
Geoscience Data Repository. Customized digital data will be available
