GSC Open File 1766/BC RGS 57 includes analytical and statistical data compiled from a reconnaissance-scale geochemical survey conducted in the Fort Fraser (NTS 93K) map sheet during 2002. Stream sediment and water samples were collected from 795 sites covering over 10,500 square kilometers at a density of one sample per 13.2 km2 (Figure 1).
Survey results include 49 variables in stream sediments, fluorine and loss-on-ignition in sediments, and pH, uranium, fluoride and conductivity in stream waters. In addition, 186 stream water samples were analyzed for trace and major elements.
There are over sixty known mineral occurrences in the Fort Fraser area including the Endako molybdenum mine. This very accessible region for exploration has potential for volcanogenic massive sulphide (VMS) mineralization mesothermal vein (Au), epithermal vein (Au, Ag) and Cu-Mo porphyry mineralization. The area is underlain by volcanic and sedimentary rocks of the Mesozoic Cache Creek, Takla and Hazelton Groups and by Jurassic-Cretaceous quartz monzonite to granodiorite plutons. A NATMAP project over the area carried out by the BC Geological Survey and the Geological survey of Canada between 1995 and 1999 included geological mapping, till geochemical and lake sediment surveys.
Geoscience BC Report 2008-5 is part of the QUEST project, which was funded by Geoscience BC in partnership with the Northern Development Initiative Trust, and covers a 46,000 square kilometre area extending from Williams Lake to north west of Mackenzie. This digital release includes results of the 2007 in-fill lake sediment and water survey as well as original data and new inductively coupled plasma mass spectrometry (ICPMS) results from a 1995 survey previously conducted in the adjacent Stuart Lake area.
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 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.
