Denison Mines Corp. (NYSE American: DNN) is a uranium exploration, development and production company with a primary focus on advancing its high-grade uranium assets in Canada’s Athabasca Basin. The company’s flagship project is the Wheeler River joint venture in northern Saskatchewan, which is one of the largest undeveloped high-grade uranium deposits in the region. Denison also holds interests in several other exploration properties, including the Waterbury Lake and Moon Lake projects, which add depth to its strategic land position in one of the world’s richest uranium mining districts.
