Guardians of Eternity confronting Giant Mine's toxic legacy
Guardians of Eternity is a documentary film about the toxic legacy of an abandoned gold mine in northern Canada. The Giant Mine is closed now, but the mess that has been left behind will be with us forever. The Yellowknives Dene First Nation is on the front line because the mine is on their land.
Guardians of Eternity is a full-length documentary film about the toxic legacy of the Giant Mine in Yellowknives, Northwest Territories. The Giant Mine was part of the founding infrastructure of the city of Yellowknife and can still be seen on the outskirts of town. It is located near the Yellowknives Dene First Nation communities of N’Dilo and Dettah and was built in 1949 without consent on Dene hunting and harvesting grounds. For a number of years highly toxic arsenic trioxide, a byproduct of the roasting process used to separate gold from the ore, spread widely from the roaster contaminating the land around the mine. Today, the majority of the arsenic, some 237,000 tones, is buried underground in frozen chambers. The Canadian and NWT governments are working to remediate the site and the current plan includes keeping the contaminants frozen, perhaps into eternity. The recently passed environmental assessment includes a number of measure, including an independent oversight body and a perpetual care plan, and includes the requirement that research into a more permanent solution be conducted and that the project be reviewed every 100 years. This is one of Canada’s most contaminated sites and understandable there is much public awareness and concern. Guardians of Eternity introduces the people who are most affected by this legacy of a gold rush and looks at the challenge of communicating the danger to future generations posed by the existence of a substance that will remain highly toxic forever.
The Giant Mine produced 7 million ounces of gold over a period of 55 years. The companies that controlled the mine made $1.1 billion (all figures in 2002 dollars) in profit and the government collected $572 million in taxes and royalties, but also provided $59 million in subsidies to the mine.
After the mine went bankrupt, Aboriginal Affairs and Northern Development Canada took responsibility for dealing with the cleaning up of the site. The Giant Mine site consists of 950 hectares containing 8 open pits, 4 tailing ponds, 100 buildings, 11,500,000 cubic feet of contaminated soils, and 237,000 tons of arsenic trioxide.
Remediation of the mine site focuses on isolating and containing the arsenic trioxide using a “Frozen Block Method.” In the short term, the estimated cost of the remediation work is $903 million. However, arsenic trioxide will remain toxic to life forever.
The Yellowknives Dene First Nation has lived on the surrounding land for centuries and now they must deal with the prospect of living with arsenic trioxide for eternity.
Director – France Benoit is a policy advisor turned filmmaker who decided to become a vegetable farmer in Yellowknife. After a feature documentary, she switched to short films and recently completed her first short fiction. She has lived in Yellowknife for 26 years. She has been directing films for more than a decade. Her film, “Un pied dans la main / Hand to Toe “ was selected for Hot Docs in 2011, the first filmmaker from the Northwest Territories to be selected. In 2008, with Les Productions Rivard of Winnipeg, Radio-Canada and RDI, France wrote and directed “One River, Two Shores, reflections on the Mackenzie Gas Project”. The documentary discusses the environmental spiritual and socio-economic consequences of the proposed natural gas pipeline which would largely follow the Mackenzie River in the Northwest Territories. The film was selected to the Rendez-vous du cinéma québécois in Montréal in 2009. Also in 2009, for the TVA show “Viens voir ici”, France completed a 30 minute episode on local food production in Yellowknife. France continues to live self-sufficiently in the boreal forest outside of Yellowknife, pumping her water from the lake, heating her home from wood and drawing her energy from the sun.

Mining and Communities in Northern Canada is a collection of articles examining the historical and contemporary social, economic, and environmental impacts of mining on Aboriginal communities in northern Canada. Combining oral history research with intensive archival study, this work juxtaposes the perspectives of government and industry with the perspectives of local communities. The oral history and ethnographic material provides an extremely significant record of local Aboriginal perspectives on histories of mining and development in their regions.

Toxic Legacies
The Toxic Legacies Project examines the history and legacy of arsenic contamination at Giant Mine. The project is a partnership among researchers at Memorial University (John Sandlos and Arn Keeling) and Lakehead University, (Ron Harpelle) the Goyatiko Language Society (a Yellowknives Dene First Nation) non-profit organization dedicated to the preservation of the Weledeh language), and Alternative North (a Yellowknife environmental and social justice coalition that conducts public interest research).
The project is a response to the Canadian government’s Giant Mine Remediation Project to freeze arsenic underground in pepetuity, a project that has recently undergone and extensvie environmental assessment. As a “Partnership Development” project (funded by the Social Sciences and Humanities Research Council (SSHRC)), we also aim to communicate our research results in a way that will engage the community of Yellowknife and the broader concerned public.
