| Abstract | Renewed exploration or development in historical mining districts, such as Cobalt, presents unique challenges for proponents and government regulators because of the cumulative nature of environmental
impacts. To increase their capacity to carry out or review environmental assessments, this project will develop geoscience methods for distinguishing environmental effects of new mining activity from complex existing background conditions in affected
watersheds. Specifically, the project will develop means of unraveling the history of accumulated polymetallic contamination from multiple sources over multiple periods. This information and new data from mine wastes and mine drainage will be
synthesized in the first geoenvironmentalmodel for Ag-Ni-Co-As vein type deposits. Project results will be disseminated to key end users in order to improve their capacity to carry out or review environmental assessments and to ensure that decision
makers have a better understanding of the cumulative nature of environmental impacts for the sustainable development of natural resources. |
| Summary | (Plain Language Summary, not published)
This presentation was an introduction about the research that will be undertaken over the next 5 years under the Environmental Geoscience Program. The
goal is to distinguish the environmental effects of natural resources development of those from natural processes. This new phase of research will be looking at marine spills, Canada's largest watershed, permafrost geochemistry, volcanic mercury
contribution, mining impacted watersheds, assessments of aquifers, diluted bitumen and permafrost degradation. |
