          In the course of NGR surveys (1975-1979), sediment and water samples were collected from more than 23 000 streams and 41 000 lakes in Canada. The surveys were carried out under the auspices of the Federal-Provincial Uranium Reconnaissance Program (URP) and Provincial Geochemical Reconnaissance Surveys. Sediments from all areas were analyzed for U, Zn, Cu, Pb, Ni, Co, Mn, Fe, Mo and those from some areas for Hg, Ag, As, V, F, W, Sn and Ba. When collected, waters were analyzed for one or all of U, F and pH. The source data have been previously published as Geological Survey of Canada Open Files and Provincial releases at a 1:250 000 scale.

          Each of the 20 Open Files consists of from 11 to 17 Xerox coloured maps, a sample location map and descriptive text.

          These files will be placed on open file for inspection February 25, 1981 at all Geological Survey of Canada libraries; Resident Geologist's office, Department of Indian and Northern Affairs, Bellanca Building, P.O. Box 1500, Yellowknife, Northwest Territories, X1A 2R3 (Open Files 737, 738, 739, 740, 741 and 742 only); and Resident Geologist's office, Department of Indian and Northern Affairs, 200 Range Road, Whitehorse, Yukon Y1A 3V1 (Open Files 730, 731, 732 and 733 only).
