Principal Investigator: Donald, Derek
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5765. The main objectives of the field work for 2023 will be (1) to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment, wildlife, and air quality; and (2) to provide baseline data for areas where mine development may occur in the future. In winter, water samples will be colle...

Principal Investigator: Brezenski, Jeff
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5636. The purpose of the baseline program field studies is to: characterize existing conditions in the project vicinity and surrounding region to support project planning, permitting, and development of a proposed lithium mine. One continuous air quality monitoring station will be installed to measure ambient concentratio...

Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5534. The long-term objective of this research is to determine what processes control the recovery of the landscape near Yellowknife that was contaminated by stack emissions from the Giant Mine roaster, and how this recovery will be affected by climate change and unusual or severe weather events. One focus will be on how cl...

Summary: This licence has been issued for the scientific research application No.5531. The overarching objective of this program is to take an ecosystem approach to assessing how multiple environmental stressors impact aquatic habitats in subarctic shield terrain. There are three central activities that will be undertaken with this license and they are designed to address the specific objectives below: ...

Principal Investigator: Amuno, Solomon A
Licensed Year(s): 2017
Summary: The objectives of this research project are to: 1. investigate the effects of chronic arsenic exposure on reproductive parameters, specifically seminal and hormonal parameters including testicular pathology and os penis (baculum) morphology of small mammals (muskrats and squirrels) inhabiting the vicinity of the Yellowknife area, near the Giant mine, and in a reference location approximately 30-8...

Principal Investigator: Wiatzka, Gerd M
Licensed Year(s): 2009
Summary: The Rayrock Mine site has been previously remediated, but additional assessment work is proposed to ensure that the remedial efforts were effective, complete, and in good condition. INAC has contracted SENES to complete a Supplementary Site Assessment, the results of which will be used to determine if there are any residual risks associated with the site and identify options to mitigate those ris...

Licensed Year(s): 2007 2006
Summary: The project objectives include the collection of information and samples to characterize the environmental conditions at the sites. The types of samples to be collected include: water (8 samples), sediment (5 samples), soil/tailings/waste rock (5 samples) and designated substances (e.g., asbestos, lead paint, PCBs, hydrocarbons). The work involves manual sampling and measurement with minimal d...

Licensed Year(s): 2007 2006 2005
Summary: The purpose of this project is to study the mobility, speciation, and mineralogical and geochemical controls on antimony (Sb) and arsenic (As) originating from the Giant Mine. This research could aid in designing reclamation plans, resolving the relation between Sb and benthic diversity and identifying threats to the Great Slave Lake ecosystem. Understanding the movement and speciation of As and S...

Licensed Year(s): 2006
Summary: The spruce and jack pine forest stands in certain areas surrounding the site of Giant Mine, north of Yellowknife, show signs of poor health; stunted growth, early leaf drops, and yellowed foliage. These symptoms may be attributed to the emissions of sulphur dioxide (SO2) and arsenic trioxide (As2O3) that were released into the atmosphere from 1949 to 1999 as by-products to the roasting process use...

Licensed Year(s): 2005 2004
Summary: Colomac Gold Mine was closed in 1996 and is now under the care and maintenance of INAC. Mine water is accumulating in the Tailings Containment Area (TCA) and the mine pits and will have to be released to the environment within a few years. Under the reme...
