The Giant Mine just outside of Yellowknife, Northwest Territories, Canada is one of the country's largest recognized environmental liabilities. The mine's 100 plus year history illustrates the continuity between resource colonialism in the late 19th/early 20th century and neoliberalism at the turn of the millennium.
There were several gold rushes in northern Canada/US in the late 19th century, such as the Klondike. The Giant gold strike on was first discovered by settlers about the same time as the Klondike, but as Giant is on Great Slave Lake (named for an Anglicization of the name of local peoples, not after slavery) instead of the Pacific Ocean, it is much less accessible and didn't take off like the Klondike. Parallel with displacement of local Yellowknives Dene people https://ykdene.com/, the town of Yellowknife sprung up around small mining operations through the 30s. It wasn't until after WW2 that the mine was developed at a large scale. Starting operation in 1948, Giant was owned by a Canadian mining conglomerate through the 80s, then some Australians, and for the last ten years of its operating life, by Americans, who went bankrupt and abandoned the property in 1999. The Canadian federal government is responsible for the site and its remediation now, similar to the way the EPA has Superfund sites in the USA.
The project is infamous for poisoning the people and environment of the surrounding area through arsenic poisoning. The ore at giant is arsenopyrite, an arsenic sulphide mineral that often contains gold. Roasting it in large furnaces or kilns releases the gold as well as fine arsenic trioxide dust. The most infamous arsenic poisoning incident was in 1951 when a Yellowknives Dene toddler in died after eating contaminated snow in the fallout area, 2 kilometers from the processing mill's smokestack. Over the years, improvements to the mill reduced the amount of toxic dust released to the environment. This is better than blasting it into the air wildly, but meant that the site accumulated hundreds of thousands of tonnes of arsenic trioxide dust that they chucked in empty mine workings underground. Unfortunately, arsenic trioxide dissolves in water as easily as sugar and so represents a tremendous risk to groundwater and waterbodies nearby, like Great Slave Lake and Yellowknife's water supply.
Arsenic issues contributed to labour disputes as well. In 1991 the union workers of the plant went on strike, refusing management's demand to reduce their salary and wanting better safety measures for workers . The company brought in Pinkertons and strikebreakers, backed by RCMP thugs. The situation escalated, culminating in a bomb planted on a train track deep in the mine. When it was triggered, it killed 6 scabs and 3 Pinkertons. For the next year, the RCMP interrogated mine workers, their family and community without determining who did it, supporting the company in their refusal to sign a new contract until an arrest was made. Finally a worker named Roger Warren confessed to doing it alone and was sentenced to life in prison. He was released in 2014 and died in 2017.
Since 1999, the site has been the responsibility of the Canadian federal government and is being every so gradually remediated. Operated through what are effectively private-public partnership contracts, environmental engineering companies are attempting to clean up and isolate the huge amounts of arsenic trioxide dust. The concept is move the dust into specially ventilated chambers of the underground mine, where it is frozen in place and thus prevented from leaching into groundwater. Active remediation is supposed to be finished in about 15 years at a cost of $1 billion CAD, but will surely take longer and cost more than this. Also, freezing material in place will definitely work because the climate isn't changing, and the Canadian north is definitely not seeing extreme levels of temperature rise.
After active works are complete, the site will require perpetual care.
