Summary: The objective of this project is to understand why arsenic trioxide (As3+) is still present in soils around Giant Mine, how long it will remain there, and if the set of circumstances leading to persistent As3+-rich soil may apply to any other places previously assumed to be As3+-free. In terms of current mine remediation, future human contact with the site, and ecosystem health, it needs to be und...

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...

Summary: Between 1948 and 1951, approximately 375 000 tons of tailings were deposited directly into Back Bay from Giant Mine along the northwest shore via a drainage channel. The submerged tailings contain high levels of metals, particularly arsenic. Over time, t...

Summary: Conduct mapping of surficial deposits based on airphoto interpretation and fieldwork. Dig small holes to obtain soil samples. Samples will be analyzed to determine their chemical composition....

Principal Investigator: Kerr, Daniel E.
Licensed Year(s): 1993
Summary: The researcher will be conducting geological field work in the region defined by the NTS Winter Lake Map (No. 86A). The work will involve surveying the land features and collecting samples of the rock and sediments in order that this information can be summarized on a geological map....
