National Geochemical Reconnaissance releases NGR 3-76 and 4-76, Regional lake sediment geochemical reconnaissance data, northeastern Manitoba (NTS 64I, 54L W½ and 64P, 54 M W½)

          These files relate to data acquired under the Federal-Provincial Uranium Reconnaissance Program, the provincial part being financed through the Canada-Manitoba Subsidiary Agreement on Mineral Exploration and Development.

          The project was jointly planned by the Geological Survey of Canada and the Manitoba Mineral Resources Division. 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 some 13,700 sq. miles at an average sample density of 1 sample per 5 sq. miles. Samples were analyzed for 12 elements (Zn, Cu, Pb, Ni, Co, Ag, Mn, Fe, U, Mo, As and Hg) and loss-on-ignition to estimate organic carbon content.

          The files consist of 26 geochemical maps, the area being divided into 2 sheets, 2 sample location maps and lists of the field and analytical data.

          A limited supply of white prints will be available for sale at the Manitoba Mining Recorder's offices at the user's expense. Copies of material may also be obtained at the user's expense by application to K.G. Campbell Corporation, 880 Wellington Street, Ottawa, Ontario, K1R 6K7. The field observations and analytical data from which the material was prepared are also available in digital from at the user's expense. Enquiries should be directed to: The Director, Computer Science Centre, Department of Energy, Mines and Resources, 588 Booth Street, Ottawa, Ontario, K1A 0E4.
