Open File 2001-13 presents the geochemistry of the Ecstall Greenstone Belt of British Columbia (103H/103I) between the Skeena River and Douglas Channel.   A total of 242 sediment samples and 241 water samples were collected from 228 sites covering over 1,800 square kilometers at a density of one sample per 7  km2. Sediment samples were analysed by INAA and aqua regia-ICPMS for base and precious metals, pathfinder and rare earth elements.  Water samples were analysed for pH, uranium, sulphate and fluoride.  This region has a high potential for the discovery of new volcanogenic massive sulphide (VMS) mineralization.  The survey was conducted in 2000.
