As part of the QUEST South regional geochemical studies sponsored by Geoscience BC, a total of 785 stream samples were collected in southern British Columbia in 2009, with analytical results published in 2010 (Jackaman, 2010).


The BC Geological Survey recently delineated catchment basins for these new infill stream sample sites, after extensive validation and adjustment of the sample locations to the TRIM streams.  Detailed methodology on the delineation of catchment basins was described and published by Cui, et al. (2009). 


The release of the catchment basin data for these sample sites is to complement and enhance the values of the Geoscience BC publication, in the advancement of the levelling, interpretation, application and presentation of the geochemical results for mineral exploration. 


All publications of the BC Geological Survey are available digitally, free of charge, from this website.
