explosion (Fullowka v. Royal Oak Ventures Inc.) In 2008, the nine Giant Mine widows lost their $10-million civil judgment when the Northwest Territories Supreme Court overturned an earlier ruling. Contamination Mining operations over five decades have created a massive environmental liability, a problem which the mine's previous owners left to the Government of Canada and Government of the Northwest Territories to sort out. The site's footprint includes 8 open pits, 4 tailing ponds, of contaminated soils, and approximately 100 buildings including a roaster/bag house complex that is highly contaminated with arsenic trioxide dust and fibrous asbestos. The remediation plan proposed by the SRK Consulting Inc. and SENES Consultants Limited, the leading technical advisors since 2000 to Aboriginal Affairs and Northern Development Canada on the Giant Mine Remediation Project, includes underground issues such as dust that contains arsenic trioxide, and remediation of the surface, water and Baker Creek. Remediation Aboriginal Affairs and Northern Development Canada reported that the "greatest challenge associated with the remediation of Giant Mine" is the safe long-term storage of the arsenic trioxide dust, the lethal byproduct of extracting gold from the mineral arsenopyrite ore stored underground. Their top priority for the Giant Mine site remediation is an "effective, long-term management" of arsenic trioxide. Arsenic trioxide dust, which contains approximately 60% arsenic, is highly lethal even in small doses. It is odourless, tasteless and semi water-soluble. The arsenic trioxide dust is stored in 15 stope or rock chambers that have been sealed with concrete approximately below the surface. The taxpayer-funded (c. $900m to approximately one billion dollars) remediation plan to permanently freeze the underground arsenic trioxide dust chambers was approved by the Canadian federal government in August 2014. According to the federal civil servant in charge of the clean-up, Jane Amphlett, using technology like that used in ice-hockey rinks, coolants will permanently freeze the storage chambers containing the arsenic trioxide dust to keep groundwater seepage out in what is called the "Frozen Block Method." A Yellowknife community museum is envisioned for part of the former Giant Mine townsite. In winter 2020 the Yellowknives Dene First Nation (YKDFN) demonstrated outside the site demanding a federal apology, compensation, and a role in the contracts for remediation. They launched their own website which details the story from their point of view.
