Description Cosigo Resources Inc (formerly Horseshoe Gold Mining) is looking for any luck it can get in its search for diamonds. The company is primarily looking for the precious gem in Canada's Northwest Territories. Cosigo, through its one-third interest in DHK Diamonds, has a stake in more than 200,000 acres in the Lac de Gras area. Its other exploration project is the Fuego gold and silver metals prospect (wholly-owned by fellow Canadian mining company Almaden Minerals) in the Oaxaca State of Mexico. Horseshoe Gold became Cosigo Resources following a reverse merger in 2011
