Geological Survey of Canada (GSC) Open File 561 presented analytical and statistical data for 11 elements in sediments from 892 stream and 75 lake sample sites. Loss-on-ignition in lake sediments, uranium, fluoride, and pH values in waters from these sites were also included in this report.

In 1990, under the British Columbia Ministry of Energy, Mines and Petroleum Resources (BCMEMPR) Regional Geochemical Survey (RGS) Archive Program, the samples collected in 1978 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 2000 as BCMEMPR RGS 52.

The regional stream and lake sediment and water survey of the Jennings River, British Columbia map sheet (NTS 104O) was undertaken by the GSC in conjunction with the BCMEMPR under the terms of the Canada - British Columbia Agreement on a Uranium Reconnaissance Program.

E.H.W. Hornbrook directed the GSC activities. N.C. Carter directed BCMEMPR activities (1978).

P.F. Matysek and W. Jackaman (BCMEMPR) managed the RGS Archive Program (1990). This initiative was funded in part by the Canada-British Columbia Mineral Development Agreement (1985-1990).
