NORTHWEST TERRITORIES - The joint venture NISHI-KHON/SNC-LAVALIN has won a $16-million contract for procurement and construction management of Dike A418 at the Diavik diamond mine.
The dike will allow temporary draining of part of Lac de Gras so that the kimberlite bodies beneath the lake can be mined. Once completed, the dike will be 1.29 km long, with a maximum height of 32 m, requiring approximately 1 million m of rockfill. The dike will also be equipped with automatic data-collection sensors for continuous monitoring of the dike and the surrounding environment. Services for the current project began in January, and construction will cover the period from May 2005 to November 2007.
The mine, operated by DIAVIK DIAMOND MINES, became Canada's second producer of diamonds in January 2003. It recovers up to 8 million carats/year. For more facts and information about the dike system, visit www.Diavik.ca.
