The Hazelton (NTS 93M) reconnaissance-scale stream sediment and water survey was completed in 1983 and the resulting field and analytical data were released in 1984. A total of 1099 sediment and 1092 water samples were collected from 1037 sample sites.

 

As part of the RGS Archive Program, 1030 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were re-published in 1998.

 

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 2009-10 is in pdf format, and analytical data in zipped excel files. The clay-sized fraction of 533 archived basal till samples collected within the Babine porphyry copper belt was analyzed for 37 elements by aqua regia digestion followed by inductively coupled plasma mass spectrometry (ICP-MS). The spatial distribution of samples elevated in Ag, As, Cu, Hg, Mo, Pb, and Zn are the focus of this study. Data presented here confirm and further constrain previously identified till geochemical exploration targets within the Babine porphyry copper belt. These data also outline two new multi-element, multi-site till geochemical exploration targets.

 

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.
