Exploration for Archean Polymetallic Sulphide Deposits in Permafrost Terrain: An integrated geological/geochemical technique; Kaminak Lake area, District of Keewatin

The paper contains 54 pages of text, 23 figures (i.e. 21, as no. 11 and 5 are excluded) and 3 tables, resulting from work done in the Ennadai Belt (Spi Lake and Kaminak Lake areas) by R.H. Ridler and W.W. Shilts from 1970 to 1973. The total area concerned is bounded by Lat. 61º45’; 62º30’N and Long. 96º30’W and 94º15’W. The exhalite metallogeny and volcanic stratigraphy of the Archean bedrock is used to interpret anomalous areal distribution of patterns of copper and zinc in tills. Anomalous concentrations of base metals are indicated over and along economically significant exhalite zones in major felsic volcanic concentrations similar to the Noranda area. Gold analyses of exhalites, ranging into ore grades, confirm the economic potential. Previously unrecognized exploration targets are indicated. The new method by which bedrock-related base metal anomalies are derived from weathered till in the active zone above permafrost is described.

The report will be available for inspection from 1:00 p.m., E.S.T., May 24, 1973 (and equivalent local times) at the libraries of the Geological Suvey of Canada, 601 Booth Street, Ottawa K1A 0E8, Ontario; the Institute of Sedimentary and Petroleum Geology, 3303-33rd Street, N.W., Calgary T2l 2A7, Alberta; the British Columbia Office, 6th Floor Sun Building, 100 West Pender Street, Vancouver 3, British Columbia and at the Office of the Resident Geologist, Indian and Northern Affairs Department, Box 1500, Yellowknife, N.W.T.
