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)
To increase the program visibility, a public science presentation was offered to the entire department (NRCan) and key partners via Tandberg and NRCan live web on May 9th, 2017. All the Power Point Presentations (7) are included in this Scientific Presentation and key words associated to the research are as follow: oil sands, groundwater, shale gas, induced seismicity, geological storage, critical metal deposits and geoscience tools.
