On June 28, 2010, De Beers, the world's largest diamond mining group, completed an agreement with Gedex Inc., a private Canadian corporation, which will assist in the commercialization of Gedex's new resource exploration technology.

De Beers has contracted with Gedex to use its unique and proprietary high definition airborne gravity gradiometer (HD-AGG(TM)) system in exploration surveys and to provide related services over several years.

De Beers was advised in the negotiation of this agreement by Robert Shirriff and Alex Nikolic of Fasken Martineau.
