NTS 094D - McConnell Creek

 

BC RGS 45  / BCGS GF2005-22 / GBC 2009-14 / GBC 2011-2

 

The McConnell Creek (NTS 94D) reconnaissance-scale stream sediment and water survey was completed in 1996 and the resulting field and analytical data were released in 1997. A total of 1034 sediment and 1034 water samples were collected from 976 sample sites, at an average sample density of 1 site every 11 square kilometres. Stream sediment samples were analyzed for precious and base metals, pathfinder elements and rare earths. Water samples were analyzed for pH, fluoride, uranium and sulphate.

 

This region is well known for its geologic and metallogenic diversity and is considered to have high potential for additional discoveries of gold-copper porphyry, gold-silver epithermal, skarn, vein and basaltic copper mineral deposits.

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.
