TERRE-NET: Controls on the Release of Contaminants from Gold Tailings at the Giant Mine, Yellowknife, NT
Principal Investigator: Blowes, David W.
Licenced Year(s): 2019 2018 2017
Summary: The goals of this research are: 1) to determine the magnitude and rate of release of arsenic and other toxic elements from the Giant Mine tailings to groundwater; 2 to evaluate remediation alternatives for tailings management, including the effects of proposed engineered covers; and, 3) to apply novel characterization techniques to understand the mechanisms controlling arsenic release. The r...

Characterization of arsenic-hosting solid phases in Giant Mine tailings and tailings dust
Principal Investigator: Bailey, Alexandra
Licenced Year(s): 2016
Summary: The primary objective of this research is to analyze near-surface tailings from the tailings ponds and shoreline at Giant Mine in Yellowknife, Northwest Territories, and to distinguish the arsenic-hosting phases in both the bulk tailings and the fine fraction of the tailings from the site. The research team will initially take near-surface samples of tailings - from which windblown dust may be ...

Investigation of the Extent of Historic Tailings in Back Bay/Yellowknife Bay
Principal Investigator: Caughill, Dave
Licenced Year(s): 2004
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...
