How and where is the arsenic trioxide currently stored?
A. The arsenic trioxide dust is stored in 15 mined-out chambers located in solid rock between 80 and 250 feet below the surface. The chambers are all located near the “C” shaft on the mine site. The arsenic trioxide is not in barrels, and the chambers are not under the lake or under the communities of N’Dilo, Dettah or Yellowknife.
