The desire of local Mormon settlers for economic self-sufficiency led to mining by missionaries for lead at Potosí. In 1858, Nathaniel V. Jones was sent to recover ore from the “mountain of lead” 30 miles southwest of the mission at Las Vegas Springs. About 9,000 lbs. were recovered before smelting difficulties forced the remote mine to be abandoned in 1857. Potosi became the first abandoned mine in Nevada.
In 1861, California mining interests reopened the mine, and a smelter and rock cabins for 100 miners made up the camp of Potosi. Even more extensive operations resulted after the transcontinental Salt Lake and San Pedro R.R. (now the union pacific) was built through the county in 1905.
During World War I, Potosi was an important source of zinc.

Originally located in April 1856, when a Paiute Indian showed Mormon miners where "heavy rock" could be found, the Potosi Mine is the oldest in southern Nevada. Opened under the direction of Nathaniel V. Jones, it operated until January 1857, when the first effort ended. The lead was too brittle for bullets due to the high zinc and silver content. By 1861, the mine was being worked by the Colorado Mining Company, but this also only lasted a few years.
With the early twentieth century mining boom in the Goodsprings area, the Potosi was reopened. In 1913, the Empire Zinc Company bought the mine, building an aerial tram and baby gauge railroad to the site. By 1915, the Potosi mine was the largest zinc producer in Nevada, in addition to significant amounts of lead and silver. Production ended about 1930.
