Geological Survey of Canada (GSC) Open File 1001 / British Columbia Ministry of Energy, Mines and Petroleum Resources (BCMEMPR) Regional Geochemical Survey (RGS) 11 presented analytical and statistical data for 14 elements in stream sediments from 1,061 sample sites, collected at an average density of one sample per 13.3 km². Uranium, fluoride, and pH values in waters from these sites were also included in this report.

In 1990, under the BCMEMPR RGS Archive Program, the samples collected in 1983 were analyzed by Instrumental Neutron Activation Analysis (INAA). These new data for gold and 25 other elements, along with original survey results, were published in 1998 as BCMEMPR RGS 49.
