Diavik Diamond Mine is Canada’s largest diamond mine. Diavik was established following the discovery of four diamond-bearing deposits, called kimberlite pipes, in 1994 and 1995.
The mine site is located in Canada’s remote wilderness on a 20 square kilometer island, at Lac de Gras, Northwest Territories, approximately 300 kilometers from Yellowknife, the territorial capital, and just 220 kilometers south of the Arctic Circle.

Harry Winston does not operate the Diavik Diamond Mine. The mine is operated by Diavik Diamond Mines Inc., a subsidiary of Rio Tinto plc, one of the largest and most highly regarded mining companies. Under the joint arrangement, Rio Tinto operates the mine and Harry Winston pays 40 per cent of the mine’s operating and capital costs while receiving 40 per cent of the mine’s diamond output.
The three kimberlite pipes currently mined, A154 South, A154 North, and A418, are small in diameter by global comparison, but are very high grade, with some of the world's highest per tonne ore value. At December 31, 2011, the Diavik Mine had 16.1 million carats of proven reserves and 42.8 million carats of probable reserves for nearly 59 million carats of total proven and probable reserves (reserves are for 100% of the Diavik Mine, in which the Company has a 40% ownership interest).
Diavik’s exceptional grades make it one of the most valuable and profitable diamond mines in the world. The current mine plan is expected to take the mine’s production to at least 2022.
Diavik began producing diamonds in January 2003, and the Company sold its first rough diamonds in March that year. Diavik diamonds are highly regarded in the international commercial marketplace. Most are one carat or larger, white in color and have good clarity, as well as being conflict-free.
