Arsenic trioxide and underground issues at Giant Mine

Processing of the Giant Mine ore created arsenic trioxide dust as a by-product. Approximately 237,000 tonnes of the dust was produced and stored underground in 15 purpose-built chambers and mined-out stopes (open holes in the mine resulting from the extraction of minerals). The dust is about 60% arsenic.
