Mines owned or run by Meridian Gold have created serious toxic pollution in at least three locations in the United States. One of the largest emitters of atmospheric mercury in the US is the Jerritt Canyon Mine in Nevada, which was part-owned by Meridian until its recent sale. This mine emits more than 10 times the amount of mercury released by a typical US power plant. The tailings facility at Jerritt Canyon has been leaking since it was constructed in the 1980s.
