DE BEERS, the world’s largest producer of diamonds, has completed its successful 305m Canadian dollar bid for the takeover of diamond producer Winspear Diamonds.The offer saw 96.2% of Winspear shareholders accept De Beers’ bid of C$5 per share. De Beers last month concluded the agreement for the acquisition of Winspear, which counts among its assets mineral-rich land in northern Canada, including the key Snap Lake project. This is forecast to produce around 1.9m carats in diamonds per year, or a total of 67m recoverable carats.
