AbstractThe goal of this activity is to test the hypothesis that climate variability controls metal(loid) cycling in the environment. We initiated research in 2015-16 to provide missing baseline geochemical data and model the cumulative impacts of geogenic and anthropogenic processes, with a focus on climate variability, on the transport and fate of metal(loids) in the vicinity of the City of Yellowknife, Northwest Territories. Due to the complex geology of the Slave Geological Province and in particular, mineralized greenstone belts and hydrothermal alteration zones, geochemical background can be highly variable even on small spatial scales. In addition, the Yellowknife region has experienced ~75 years of gold ore mining and processing that resulted in release of substantial quantities of arsenic to the surrounding environment. The larger POLAR Knowledge Canada S&T funded activity will also focus on the Courageous Lake area that is thought to have been impacted by free-milling gold mining and processing at Tundra, Salmita, and Bulldog mines in the 1960s and 1980s, and the yet to be developed Hope Bay area (TMAC Resources Ltd.) in the central and northern Slave Geological Province, respectively.
Summary(Plain Language Summary, not published)
The environmental geoscience program is a federal research program that aims to provide Canadians with advanced scientific information to differentiate the effects of the development of natural resources on the environment of those of natural processes. Following this mandate, the development of new geoscientific approaches is used to support the developement and responsible use of Canada's natural resources by making informed decisions while protecting Canadians and their environment. Advancing scientific understanding about natural resources development will inform policy makers and have direct implications on future decisions. To increase the program visibility, a public session was offered in May 2016 to the Earth Science Sector and other key partners from Natural Resources Canada. All the information presented during the public session is included in this Open File.
