New QUEST Lake Sediment Geochemistry and Preliminary Airborne Gravity Images Released

April 1, 2008- Geoscience BC is pleased to release new lake sediment geochemistry and preliminary airborne gravity images collected as part of the QUEST Project.

Geoscience BC Report 2008-5 reports results from an in-fill lake sediment and water survey which includes new samples from over 1800 sites in NTS sheets 093G, J, N and O, as well as new inductively coupled plasma mass spectrometry (ICPMS) reanalyzed results of sample pulps from a previous lake survey in the Stewart Lake area (part of 093K). The report includes survey descriptions and details regarding methods, field and analytical data listings, summary statistics, sample location map, geology map and maps for individual metals. Raw digital data files used in the production process are included in XLS and DBF formats. The project was managed by Noble Exploration Services Ltd.

Geoscience BC is also releasing Geoscience BC Report 2008-6, which contains three preliminary PDF and geocoded bitmap images of the QUEST airborne gravity survey, which was undertaken by Sander Geophysics Ltd. This gravity survey covers the same footprint as the QUEST VTEM survey (released in January 2008), but was flown with a 2 km line spacing. The final airborne gravity data and images will be released at a later date.

Geoscience BC is also pleased to announce that ten georeferenced TIF images of QUEST data released at Roundup are now available for download from GBC's website. This new set includes eight images of reanalyzed geochemistry in the QUEST Project area, as well as two images of the Geotech VTEM data. The PDF versions of these images, released in January 2008, are still available for download from Geoscience BC's website.

In addition, draft images of Natural Resources Canada's (NRCan) airborne magnetics and ground gravity data are available for download. These images were created by Geoscience BC, using freely-available NRCan data which can be downloaded from:, and proprietary visualization software developed by C. Barnett of BW Mining. The images are available in both georeferenced TIF and PDF format.
