AbstractRenewed 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 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 geoenvironmental model for Ag-Ni-Co-As vein type deposits. Project results will be disseminated to key end users in order to improve the environmental assessment process and to ensure that decision makers have a better understanding of the cumulative nature of environmental impacts for sustainable mineral resource development.
Summary(Plain Language Summary, not published)
The goal of the Environmental Geoscience program (EGP) is to distinguish the environmental effects of natural resource development from those produced by natural processes, and to develop new approaches to support the sustainable use and development of Canada's natural resources through informed decision-making. The ultimate outcome of EGP is to increase the effectiveness and efficiency of Canadian environmental regulation and oversight. By developing innovative geoscience for environmental stewardship, as well as increasing public and private sector access to research findings, decision-makers have a greater capacity and are more empowered to carry out and review environmental assessments. This SP highlights the 5 public presentations provided on May 11, 2021 as well as all updates from all projects under the EGP.
