[Northwest Territories Mining] Giant Mine rehab contract awarded (Mining Journal – February 20, 2018)


Canada’s government has awarded a main construction manager contract as part of a multimillion dollar remediation of the storied Giant Mine near Yellowknife in the Northwest Territories.

The abandoned gold mine operated from 1948-1999 when its last owner Royal Oak Mines entered receivership.

The government said the site was one of the highest priority contaminated areas with the federal property inventory and required ongoing management to protect human health and safety and the environment.

The scope includes tailings management, building demolition, pit closures, dealing with contaminated soils and “in-situ encapsulation” of the 237,000 tonnes of arsenic trioxide stored in underground chambers.

Parsons Inc was appointed main construction manager and will provide work over two terms, with the first term to cost up to C$32 million and take until March 2020, centred around responsibility for care and maintenance and planning for full remediation in Term 2 starting in 2020.

“The cost estimate of Term 2 will be determined following design work undertaken in Term 1,” a joint statement, from Minister of Crown-Indigenous Relations and Northern Affairs Carolyn Bennett and Public Services and Procurement Minister Carla Qualtrough, said.
