History of Giant Mine for EA

August 17, 2012

The Abandoned Mines team leads, John Sandlos and Arn Keeling, recently prepared a historical summary of the arsenic problem at Giant Mine for submission to the Mackenzie Valley Review Board. The board is conducting an environmental assessment of remediation alternatives for the 237,000 tons of arsenic trioxide stored underground, a byproduct of 50 years of mining at the site. This toxic material poses a major threat to the Yellowknife area environment and public health, as well as the challenge of managing this toxic site in perpetuity (and issue we wrote about earlier in the summer).

The environmental assessment public registry is accessible to the general public. You can find our report here.
