Sediment samples were collected from Slipper Lake and Lac du Sauvage in March 1997. Study of the different types of algae in the sediment cores from Slipper Lake showed a continuing pristine, clean water lake with increasing acidity beginning around the year 1820. These changes in algae throughout the sediment core may also be related to climatic warming. Analysis of metal in the cores showed no significant changes over time. The sediment cores taken from Lac du Sauvage were not usable.
Caribou seem to be attracted to mining infrastructure such as tailings ponds, airstrips and roads.
In this project, researchers and remote cameras observed caribou behaviour around mine sites and tested two methods of diverting caribou from mine sites and other developments. Native elders were involved in designing the tradition-based test barrier and in observing and commenting on the caribou behavior. Researchers also measured temperature, wind and fly activity, and documented other caribou behavior around the mine site. It was found caribou were resting on tailings areas and feeding nearby even when mosquitoes were not present, possibly because there is no cover to conceal predators. Researchers also collected plants and measured dust levels near the roads and tailings ponds to see whether the dust affects which types of plants grow in an area.
