It has been estimated that uranium oxide (from which natural uranium is extracted) has a recoverable price of less than $22/kg, which is 840,000 tons. The current production of uranium oxide is 23,000 tons per year (including 14,000 tons in the United States, 4,000 tons in Canada, 3.8 tons in South Africa, 1.3 tons in France, 450 tons in Central Africa, 120 tons in Portugal, and several in Argentina and Japan).
