NTS 94C - Mesilinka River


BC RGS 47 / GBC 2009-14 / GBC 2011-2

The Mesilinka River (NTS 94C) reconnaissance-scale stream sediment and water survey was completed in 1997 and the resulting field and analytical data were released in 1998. A total of 1068 sediment and 1055 water samples were collected from 1008 sample sites.


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 2011-2 reports on the Northern BC Reanalysis Project -a continuation of a series of large-scale reanalysis initiatives that have been sponsored by Geoscience BC since 2007.  Recognized as a cost-effective means of updating information collected during older government funded regional geochemical surveys, these programs have significantly improved the BC geochemical database by providing a wide range of new analytical information at improved detection levels plus greater data compatibility with analytical methods currently being employed.  Digital data file includes new ICP-MS analytical results for a total of 7,651 stream and lake sediment samples.
