The Diavik Diamond Mine is a diamond mine in the North Slave Region of the Northwest Territories, Canada, about 300 kilometres (186 miles) north of Yellowknife. It has become an important part of the regional economy, employing 700, grossing C$100 million in sales, and producing 8 million carats or about 1,600 kg (3,500 lb) of diamonds annually. The area was surveyed in 1992 and construction began in 2001, with production commencing in January 2003. It is connected by an ice road and Diavik Airport with a 5,235 feet (1,596 m) gravel runway regularly accommodating Boeing 737 jet aircraft.
The mine is owned by a joint venture between the Aber Diamond Corporation and Diavik Diamond Mines Inc., a subsidiary of Rio Tinto Group. The lifespan of the mine is expected to be 16 to 22 years.
The mine consists of three kimberlite pipes and is located on an island 20 square kilometres (8 sq mi) in Lac de Gras and is informally called East Island. It is about 220 kilometres (137 mi) south of the Arctic Circle.
