Project History

1986-1994 Lake of the Woods region, northwestern Ontario till sampling survey carried out in 1986-1989.
  Glacial geological mapping and drift prospecting were conducted in the Lake of the Woods area to aid exploration for gold and base metals. Some of the main objectives of the project were to define abundances and dispersal patterns of selected rocks, mineral and trace elements in till, the principal Quaternary deposit used for drift prospecting studies; to define till geochemical anomalies; and to identify other characteristics of Quaternary drift which could be applicable to waste disposal, ground water studies and aggregates. The data are published in GSC Memoir 436.
