Senior Vice President, Exploration Division: Martin Doyle

De Beers Canada Inc., a unit of global diamond miner De Beers Group, has been active for nearly 50 years, growing from a small group of geologists in the field to multiple offices and operations across the country, including the Snap Lake Mine and the Gahcho Kué advanced exploration project in Northwest Territories. The Snap Lake Mine, Canada’s only fully underground diamond mine, is located about 220 kilometers, or 135 miles, northeast of Yellowknife and has a 20-plus year mine life. The mine officially opened in July 2008 and is currently ramping up to reach full production at Snap Lake by the end of 2012.

De Beers also is advancing the Gahcho Kué diamond project with 49 percent joint venture partner Mountain Province Diamonds Inc. Gahcho Kué, one of the largest diamond deposits under development in the world, consists of a cluster of kimberlites, three of which have an indicated resource of about 30.2 million metric tons grading 1.67 carats per metric tons (about 50.5 million carats) and an inferred resource of about 6Mt grading at 1.73 cpt (about 10.3 million carats). The Gahcho Kué project is currently the subject of a C$10 million independent definitive feasibility study conducted by JDS Energy and Mining, which was due for completion in September.
