The Det'on Cho Nuna Joint Venture will ensure the former gold mine site meets environmental standards over the next 21 months, federal Aboriginal Affairs and Northern Development Minister John Duncan stated in a release Wednesday.
As part of the contract, the joint venture will also operate the site's effluent treatment plant, and protect the property.
The Giant Mine produced 7.6 million ounces of gold from 1948 to 2004, but it also produced 237,000 tonnes of arsenic trioxide — a toxic byproduct of gold production — that is currently stored in underground vaults.
After the mine's owner, Royal Oak Mines Inc., went into receivership in 1999, the federal and territorial governments began co-managing the site.
The Mackenzie Valley Environmental Impact Review Board is conducting an environmental assessment of the federal government's remediation and cleanup plan for the mine site.
The Det'on Cho Nuna Joint Venture is a partnership between Det'on Cho Corp., which is the economic development arm of the Yellowknives Dene First Nation, and Nuna Logistics Ltd. which is 51 per cent owned by Inuit in Nunavut.
The joint venture has won the federal maintenance contract for Giant Mine each time it has been put to tender in 2005 and 2007. The federal Public Works Department extended the latter contract by a year in 2010.
The latest contract runs until March 31, 2013.
