The regional lake sediment and water survey in northwestern Ontario (NTS 52C) was conducted during the summer of 1979.

This report presents analytical and statistical data for gold and 25 other elements obtained by re-analyzing lake sediments from 510 sites, collected at an average density of one sample per 15.8 km². Original analytical data selected from Open File 676 (published 1980) for 12 variables in sediments, and uranium, fluoride, and pH values in lake waters are also included in this report.

The original reconnaissance survey was managed by the Geological Survey of Canada in conjunction with the Ontario Ministry of Natural Resources according to the specifications established under the former Canada - Ontario Uranium Reconnaissance Program. Sample preparation, analytical, contract and technical support costs were financed by the Province of Ontario. The reanalysis program was undertaken under the Canada - Ontario Mineral Development Agreement (1985-1990).

E.H.W. Hornbrook directed the original survey (1979) and the reanalysis program (1990).

P.W.B. Friske coordinated the activities of contract and Geological Survey of Canada staff (1990).
