NTS 92P - Bonaparte Lake


BC
RGS 4/36
/ GSC OF 775/735 / GBC 2007-6 / GBC 2010-4 / GBC 2010-13

The Bonaparte Lake (NTS 92P) reconnaissance-scale stream sediment and water survey was completed in 1979 and the resulting field and analytical data were released in 1980. A total of 913 sediment and 834 water samples were collected from 863 sample sites.

 

As part of the RGS Archive Program, 898 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were re-published in 1992.

 

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.

 

In 2010, Geoscience BC, under the QUEST-South Project released Geoscience BC Report 2010-4 which shows new analytical results for a total of 8256 stream sediment samples that cover parts of NTS map sheets 082E, L, M and 092H, I, J, O, P.  These government-funded surveys were originally conducted from 1976 to 1981 as part of the National Geochemical Reconnaissance (NGR) program (Lett, 2005).  The new data has been carefully checked for analytical quality using blind duplicate samples and control reference material. 

 

Geoscience BC Report 2010-13, contains results of the 2009 infill surveys and parts of this package incorporate data from previous regional stream and lake based surveys completed in the study area as well as the new reanalysis results. This information 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 formats.
