MapPlace Home

Details: Mount Milligan Geophysics covers four geophysical surveys: The 1991 Mount Milligan survey is represented in BCMEM Open File 2005-9 and GSC OF 2535 and the 1995 Inzana-Salmon Lake (Mount Milligan South) survey is represented in BCMEM Open File 2005-9 and GSC Open File 2801.  The 2004 Mount Sylvester survey is represented in BCMEM Open File 2005-14 and the 2004 Fran Property survey is represented in BCMEM Open File 2005-15. The files are also available for download in georeferenced TIF and PNG formats and GeoSoft gridded data (.grd) format.  The surveys were posted to MapPlace April 8, 2005.

Survey Summaries:

Multiparameter (gamma-ray, magnetic) geophysical surveys are useful in mineral exploration and bedrock mapping studies. These surveys cover rocks of the Quesnel Terrane, a belt prospective for bulk tonnage copper-gold deposits similar to the well-known Mount Milligan deposit.

 

These surveys were published to MapPlace on April 8, 2005. The MapPlace data includes digital gridded images for 2 magnetic and 7 radiometric parameters for each survey area. The downloadable files from the British Columbia Ministry of Energy and Mines website will be 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 area also available.  A full product release (in late spring 2005) of the Mount Sylvester and Fran Property surveys will be made by the Geological Survey of Canada as a series of Open Files, including printed colour maps, images of the printed maps in PDF format, and digital line and grid data.

In 1991 the Geological Survey of Canada conducted a multisensor (gamma-ray spectrometric, magnetic total field) helicopter-borne geophysical survey in the Mount Milligan area, British Columbia, Canada. This data was published as GSC Open File 2535 in 1992 and to MapPlace as BCMEM Open File 2005-9 on April 8, 2005.

In 1995 the Geological Survey of Canada conducted a multisensor (gamma-ray spectrometric, magnetic total field) helicopter-borne geophysical survey in the Inzana-Salmon Lakes (Mount Milligan South) area, British Columbia, Canada. This data was published as GSC Open File 2801 in 1995 and to MapPlace as BCMEM Open File 2005-9 on April 8, 2005.

 

MOUNT SYLVESTER GEOPHYSICAL SURVEY

In 2004 the Geological Survey of Canada conducted a multisensor (gamma-ray spectrometric, magnetic total field) helicopter-borne geophysical survey in the Mount Sylvester area, approximately due west of MacKenzie, British Columbia, Canada. Flight lines were oriented E-W, spaced at 500 m intervals. The survey was flown under contract by Fugro Airborne Surveys. Funding was provided by the British Columbia and Yukon Chamber of Mines Rocks to Riches Program, under a project submitted by the District of MacKenzie. Support for the Geological Survey of Canada’s Radiation Geophysics Section, acting as the Scientific Authority for the survey, was provided under Natural Resources Canada – Earth Sciences Sector’s Northern Resources Development Program. This survey covers rocks of the Quesnel Terrane, a belt prospective for bulk tonnage copper-gold deposits similar to the well-known Mount Milligan deposit.

 

This data was published to MapPlace as BCMEM Open File 2005-14 on April 8, 2005. A full product release (in late spring 2005) was made by the Geological Survey of Canada as a series of Open Files, including printed colour maps, images of the printed maps in PDF format, and digital line and grid data.

 

FRAN PROPERTY GEOPHYSICAL SURVEY

In 2004 the Geological Survey of Canada conducted a multisensor (gamma-ray spectrometric, magnetic total field) helicopter-borne geophysical survey in the Fran Property Area, southwest of Mount Milligan, British Columbia, Canada. Flight lines were oriented N-S, spaced at 150 m intervals. The survey was flown under contract by Fugro Airborne Surveys. Funding was provided by Yankee Hat Industries Corp. Support for the Geological Survey of Canada’s Radiation Geophysics Section, acting as the Scientific Authority for the survey, was provided under Natural Resources Canada – Earth Sciences Sector’s Northern Resources Development Program.

 

This data was published to MapPlace as BCMEM Open File 2005-15 on April 8, 2005. A full product release (in late spring 2005) was made by the Geological Survey of Canada as a series of Open Files, including printed colour maps, images of the printed maps in PDF format, and digital line and grid data.

 

Analogue and digital products include data for eight radiometric and two magnetic parameters:
