Canadian miner Uranium One is selling a controlling stake to a Russian state-owned corporation in exchange for interests in two Kazakhstan uranium mines, plus US$610 million in cash. Through the deal, Uranium One will acquire a 50 percent interest in Akbastau and a 49.67 percent interest in Zarechnoye from JSC Atomredmetzoloto, known as ARMZ. In return ARMZ, which already holds 23.1 percent of Uranium One's outstanding shares, will increase its stake in the Vancouver-based miner to at least 51 percent.
