Dominion Diamond Corporation (TSX: DDC, NYSE: DDC) is a Canadian diamond mining company with ownership interests in two major producing diamond mines situated approximately 200 kilometers south of the Arctic Circle in Canada’s Northwest Territories. The Company operates the Ekati Diamond Mine (in which it owns an 88.9% controlling interest, as well as a 65.3% in the surrounding areas containing additional resources), and also owns 40% of the Diavik Diamond Mine. It supplies rough diamonds to the global market through its sorting and selling operations in Canada, Belgium and India and is the world’s third largest producer of rough diamonds by value.
Diavik Diamond Mine戴维克钻石矿，是加拿大最大的钻石矿。
The 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.
Diavik began producing diamonds in January 2003, and the Company sold its first rough diamonds in March that year. Diavik diamonds are conflict-free and highly regarded in the international commercial marketplace. Most are one carat or larger, white in color and have good clarity. Diavik’s exceptional grades make it one of the most valuable and profitable diamond mines in the world.
Dominion Diamond Corporation 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 Dominion Diamond 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 being 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, 2013, the Diavik Mine had 31.4 million carats of proven reserves and 14.9 million carats of probable reserves for 46.3 million carats of total proven and probable reserves (reserves are for 100 per cent of the Diavik Mine, in which the Company has a 40 per cent ownership interest).
The current mine plan is expected to take the mine’s production to at least 2022.
Ekati Diamond Mine Ekati钻石矿是加拿大第一个露天和地下钻石矿
The Ekati Diamond Mine (named after the Tlicho word meaning ‘fat lake’) is Canada’s first surface and underground diamond mine. It officially began production in October 1998, following extensive exploration and development work dating back to 1981. Like Diavik, the Ekati mine site is located in the Lac de Gras region of the Northwest Territories, approximately 300 kilometers northeast of Yellowknife.
The Ekati mine is renowned for the premium gem quality diamonds it produces. The largest gem quality diamond produced to date at the mine is the 78 carat Ekati Spirit, which was discovered in 2010 and sold at auction in 2011. A production milestone of 50 million carats was achieved in 2011.
The Company’s interests in the Ekati mine include: 88.9 per cent of the Core Zone (current operations and other permitted kimberlite pipes) and 65.3 per cent of the Buffer Zone (development and exploration potential).
Over the mine’s early years, production was focused on six open pits. Current production at the Ekati Diamond Mine includes ore sourced primarily from the Fox open pit (which is lower-grade, but high carat value), supplemented by underground production from the lower portion of the Koala and Koala North kimberlite pipes.
While carat production in the next two years is expected to be lower than the average achieved over the last five years, it is expected to return to higher carat production as the mine transitions to production from the Misery and Pigeon open pits, which have higher grades, but lower carat values. The current Ekati mine plan calls for a further seven years of production to 2019, but there are additional resources which could become economic with increased diamond prices.
