The Quesnel (NTS 93B) reconnaissance-scale stream sediment and water survey was completed in 1980 and the resulting field and analytical data were released in 1981. A total of 759 sediment and 750 water samples were collected from 715 sample sites.

 

As part of the RGS Archive Program, 1241 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were published in 2001.

 

Geoscience BC Report 2007-6 reports new lake sediment and water data covering over 16,000 square kilometers of previously un-surveyed ground in central BC, and represents a significant addition to the provincial geochemical database.

 

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 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.
