Uranium mining in New Mexico : ウィキペディア英語版 | Uranium mining in New Mexico Uranium mining in New Mexico was a significant industry from the early 1950s until the early 1980s. Although New Mexico has the second largest identified uranium ore reserves of any state in the United States (after Wyoming), no uranium ore has been mined in New Mexico since 1998. ==White Signal district== The first uranium production in New Mexico was a minor amount of autunite and torbernite mined circa 1920 from former silver mines in the White Signal district, about southwest of Silver City in Grant County.〔Lovering, T. G. (1956) ''Radioactive Deposits of New Mexico'', US Geological Survey, Bulletin 1009-L, p.329.〕
