The Rio Grande Resources Mt Taylor Uranium Mine was originally developed in the 1970s by Gulf Mineral resources and placed in production in 1980. Following a 1985 merger, the corporation name was changed to Chevron Mineral Resources. Uranium was extracted from a depth of over 3,000 feet through two shafts and hoists. The ore was transported to Chevron's Panna Maria mill in south Texas for processing. Mining operations were suspended in 1990 as a result of depressed uranium prices and the facility was placed on standby.

In 2013, Rio Grande Resources, which acquired the property in 1991, made application to reactivate the mine but took no further action. The Mt. Taylor mine contains an in-place resource of over 100 million pounds U3O8 (38,500 mtU). Presently, the deposit is being evaluated for development as an in situ leach operation.
