This global diamond conglomerate has set up offices in Yellowknife due to the influx of local diamond mining. This office oversees affairs at the nearby Snap Lake Mine. Diamond mining, exploration, manufacturing and retail is the company's specialty.
Since its opening in 1998, the Ekati Diamond mine has come to produce four per cent of the world's diamond supply by weight and six per cent by value. The mine is located 300 km northeast of Yellowknife and is operated by BHP Billiton Diamonds Inc. Diamonds are sent from the mine to the Yellowknife office, where they are cleaned and prepared for appraisal.
