NTS 93C and F - Anahim Lake and Nechako River


BCGS GF 2006-10 / GBC R2006-4/BCGS GF 2006-11 / GBC R2007-10 / GBC R2009-5 / GBC R2009-11 / GBC R2009-14 / GBC R2014-10 / GBC R2015-09

During the 2005 field season, Geoscience BC funded two reconnaissance-scale drainage sediment and water surveys in central British Columbia.  The Anahim Lake and Nechako River (NTS 093C & F) resulting field and analytical data were released July 7, 2006. A total of 106 sediment and 1962 water samples were collected from 1957 sample sites.  This includes 489 samples from a lake survey conducted in 1993 (Open File 1994-19).

 

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 2006-4 / BC Geological Survey GeoFile 2006-11 includes results of the surveys. The data has been provided in a variety of digital formats. PDF files include 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 and basemap coverages as Arc SHP files.

 

Geoscience BC Report 2007-10 is aimed at enhancing the discovery of concealed mineral deposits using the halogen elements, focusing on soil and common vegetation from three target areas: Mount Polley (Imperial Metals Corp); QR (Cross Lake Minerals Ltd.); and 3Ts (Silver Quest Resources Ltd.) on NTS 93A and 93F mapsheets.

 

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 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. 

 

Geoscience BC Report 2014-10 is part of the Targeting Resources for Exploration and Knowledge (TREK) Project and shows geochemical and mineralogical data from the first year of the surface geochemistry survey that focused on the eastern portion of the TREK Project area.  Basal till is the primary sample medium and was targeted using basal potential maps produced for this project.  Lake sediment samples were collected in areas where basal till is not present.

 

Geoscience BC Report 2015-09 is a report on the Geochemical Reanalysis of Archived Till Samples, TREK Project, Interior Plateau, central BC (parts of NTS 093C, 093B, 093F & 093K)." Short for Targeting Resources through Exploration and Knowledge, TREK is Geoscience BC's current regional project focused on BC's Interior Plateau, an underexplored area that is considered highly prospective for mineral resources.
