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. Many of Canada's largest gold deposits are hosted in complex geologic environments that posses long-lived histories. Identifying how gold fits into this complex history is important for mineral exploration. This poster reports new ages that bracket the timing of gold at the Meliadine gold district. Our results have implications for identifying prospective structures under cover.
