British Columbia is suited for using drainage geochemistry to find new mineral resources.  As a result the British Columbia Geological Survey started a regional stream sediment and stream water geochemical survey (RGS) in 1976 as part of the Geological Survey of Canada National Geochemical Reconnaissance Program. This survey now covers about 70 percent of the province with field and analytical data from the collection and analysis of over 55 000 stream sediment, lake sediment, moss mat sediment and surface water samples.


Geofile 2008-1 is an atlas of gold, arsenic, cobalt, copper, iron, manganese, molybdenum, nickel, lead, uranium and zinc geochemical maps created from the analyses of stream, lake and moss sediment samples collected throughout British Columbia. Background variations between some of the elements in the different samples types have been reduced by adjusting the source data using levelling procedures. The atlas maps are accompanied by element data files and documentation.
