The Prince George (NTS 93G) reconnaissance-scale stream sediment and water survey was conducted in 1984 and 1985. The resulting field and analytical data were released in 1986. A total of 1159 sediment and 1054 water samples were collected from 1095 sample sites.


Geoscience BC Report 2008-3 is a digital release that reports on geochemical results from a reanalysis of almost 5,000 archived stream and lake sediment samples collected in the region over 10 years ago.


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 2013-8 map shows ice flow patterns for NTS 093G, H (west) and J, and detailed ice flow history for parts of NTS 093J (near Prince George, BC).  The report also contains a regional ice flow model for the northern Interior Plateau region.  Constructed from previous mapping and recent field studies, the report is intended as an aid to mineral exploration in central BC. The report consists of one PDF sheet, and the ESRI ArcGIS shapefiles of striations, regional ice flow and detailed ice flow data.


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.

The 1984 survey was undertaken by the British Columbia Ministry of Energy, Mines and Petroleum Resources (MEMPR) and the Geological Survey of Canada (GSC).  The 1985 survey was funded by the Canada-British Columbia Mineral Development Agreement.
