The Saghand Uranium Mine will extract low-grade underground uranium ore, which will presumably be processed in the associated Ardakan Yellowcake Production Plant. [1] Starting in 1989, Iran reportedly received assistance from China and Russia with both exploration and construction.[2] The maximum projected production output of the Saghand facility is 50 tons of uranium per year.[3] There are approximately 1400 tons of uranium reserves in the ore field.[4] Construction of the extraction infrastructure had nearly been completed in 2004 with production expected to begin in 2006.[5] However, construction continues at the site and neither the mine nor the Ardakan facilities appear to be operating as of November 2010.[6]
