Geological Survey of Canada (GSC) Open File 865 / British Columbia Ministry of Energy, Mines and Petroleum Resources (BCMEMPR) Regional Geochemical Survey (RGS) 7 presented analytical and statistical data for 14 elements in stream sediments from 941 sample sites, collected at an average density of one sample per 17.1 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 1981 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 1994 as GSC OF 2665 / BCMEMPR RGS 39.

Acknowledgements:

The original reconnaissance survey of the Hope, British Columbia map sheet (NTS 92H) was managed and funded by the British Columbia Ministry of Energy, Mines and Petroleum Resources as part of the Regional Geochemical Survey Program. Data management was provided by the Geological Survey of Canada.

The reanalysis program was funded in part by the Canada - British Columbia Mineral Development Agreement (1985 - 1990) and the GSC provided funds for the INAA determination.

The reanalysis program was managed by the Geological Survey Branch staff of the MEMPR.

P.F. Matysek and W. Jackaman coordinated the operational activities of contract and MEMPR staff.
