National Geochemical Reconnaissance Release NGR 19-1977, Regional lake sediment and water geochemical reconnaissance data, Northeastern Saskatchewan, NTS 63L and parts of 64M

          This file relates to data acquired under the Federal Provincial Uranium Reconnaissance Program, the provincial part being financed through the Canada-Saskatchewan Agreement on a Uranium Reconnaissance Program.

          The project was jointly planned by the Geological Survey of Canada and the Saskatchewan Department of Mineral Resources. The contracts for field work, sample preparation and sample analysis were let, supervised and monitored by the Geochemistry Section, Geological Survey of Canada.

          The survey covers approximately 11 900 km ² (4600 mi ²) at an average sample density of one sample per 6.25 km ² (2.41 mi ²). Lake sediments were analyzed for U, Zn, Cu, Pb, Ni, Co, Ag, Mn, Fe, Mo, Hg and As and loss-on-ignition to estimate organic carbon content. Lake waters were analyzed for U, F and pH.

          Each open file consists of 13 geochemical maps, sample location map and a text of field observations and analytical and statistical data. The total area is covered in one open file.

          This file will be placed on Open File for inspection from 1:00 EDT, Thursday, June 1, 1978 (and equivalent local times) at all the libraries of the Geological Survey of Canada; at the Saskatchewan Department of Mines and Resources, 1914 Hamilton Street, Regina and the Mining Recorder's office at Creighton, La Ronge and Uranium City, Saskatchewan; and at the Ontario Ministry of Natural Resources, Public Service Centre, 6th Floor, Whitney Block, Queen's Park, Toronto, Ontario.

          A limited number of white prints and text will be available for sale at Regina and the Mining Recorder's offices, Saskatchewan. White print and text copies may also be obtained at the user's expense by application to Campbell Reproductions, 880 Wellington Street, Ottawa, Ontario, K1R 6K7. The field observations and analytical data in the text from which the maps were prepared are also available in a digital form at the user's expense from The Director, Computer Science Centre, Department of Energy, Mines and Resources, 588 Booth Street, Ottawa, Ontario, K1A 0E8.
