NTS 93E - Whitesail Lake / RGS 16 /

GSC OF 1360 / BCGS GF2006-10 / GBC 2009-5GBC 2009-11 / GBC 2009-14GBC 2010-10

The Whitesail Lake (NTS 93E) reconnaissance-scale stream sediment and water survey was completed in 1986 and the resulting field and analytical data were released in 1987. A total of 951 stream sediment and 933 water samples were collected from 898 sample sites. The survey also included the collection of lake sediment and water samples from 214 sites.


Stream sediment analyses, from several regional geochemical surveys(093D,C,E), carried out by the BC Geological Survey in the Bella Coola area have been compiled into GeoFile 2006-10 for convenience and to accompany recent geological map product releases from the Geological Survey of Canada and the BC Geological Survey.


Geoscience BC Report 2009-5 is part of the QUEST-West project, which covers over 40,000 kilometers from Vanderhoof and Fort St. James to Terrace and Kitimat. The Regional District of Bulkley-Nechako, Northern Development Initiative Trust and the BC Geological Survey (Ministry of Energy, Mines and Petroleum Resources) partner with Geoscience BC on this project. This digital release includes inductively coupled plasma mass spectrometry (ICP-MS) results for a total of 3479 archived stream and lake sediment samples that cover parts of NTS map sheets 93E, F, L, and M. 


Geoscience BC Report 2009-11 is part of the QUEST-West project, which covers over 40,000 kilometers from Vanderhoof and Fort St. James to Terrace and Kitimat. Geoscience BC in partnership with the Northern Development Initiative Trust and the Regional District of Bulkley-Nechako funded an infill drainage sediment and water survey in 2008 conducted in central British Columbia. This digital release includes results of the 2008 infill survey and parts of this package incorporate data from a number of previous lake and stream based surveys completed in the study area as well as the new reanalysis data that were released in January 2009 as part of the QUEST-West Project.


Geoscience BC Report 2009-14 is an investigation using SiroSOM for the Analysis of QUEST Stream-Sediment and Lake-Sediment Geochemical Data on all NTS sheets for 93 and 94 A, B, C and D. 



In 2010, Geoscience BC, under Geoscience BC Report 2010-10, collected 79 basal till samples within the Nadina River map area that were analyzed for 37 elements by inductively coupled plasma mass apectrometry (ICP-MS).  See also BCGS Open File 2010-07.
