Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. Past producing mines in the Echo Bay region on the eastern shore of Great Bear Lake extracted radium, uranium, silver, copper, cobalt, nickel, lead and bismuth. The Echo Bay area occupies part of an ancient volcanic belt known as the Great Bear magmatic zone in the Northwest Territories. The belt hosts the only two Iron Oxide Copper-Gold (IOCG) deposits discovered in Canada: NICO and Sue Dianne (gold, cobalt, bismuth, copper, silver).
