The third (TGI) provides integrated geoscience knowledge pertaining to areas of high base metal potential, with the intent of stimulating private-sector resource exploration. The TGI3 project at Flin Flon is a collaboration of the Geological Survey of Canada, the Manitoba and Saskatchewan geological surveys, Hudson Bay Exploration and Development Company Ltd. and Laurentian University.
