Diavik diamond mine
The Diavik Diamond Mine is located in the North Slave Region in the Northwest Territories of Canada , approximately 300 km north of Yellowknife .
As an important regional economic factor, it employs 700 people, has CAN $ 100 million in sales and mines 8 million carats or 1.6 tons of diamonds annually. Research in the area began in 1992, construction of the mine began in 2001, and normal operations began in January 2003. The mine is the Tibbitt to Contwoyto Winter Road connected, there is only two months a year, and has the airport Diavik Airport with a 1,596 meter long gravel - runway that the Boeing 737 is designed.
The owner of the mine is a joint venture between the Canadian Dominion Diamond Corporation (formerly Harry Winston Diamond Corporation ) and Diavik Diamond Mines Inc., a subsidiary of the Rio Tinto Group . The mine has been in operation for 16 to 22 years.
The mine is located on a 20 square kilometer island in Lac de Gras and is informally called "East Island". It is located 220 km south of the Arctic Circle .
Due to the mild winter of 2006, the ice road was opened late and closed early, which meant that Diavik had to fly in the rest of the cargo in order to keep operations going.
The Diavik mine was the subject of the documentary series Ice Road Truckers . In October 2018, a 552-carat diamond was found in the mine, the largest in North America to date.
