Potosi
Clark County, NV
Seeking economic self-sufficiency, Mormon settlers turned to mining lead at Potosi in the late 1850s, when Nathaniel V. Jones was dispatched to work the “mountain of lead” southwest of the Las Vegas mission, though smelting troubles soon forced the remote mine to close—making it the first abandoned mine in Nevada. California interests reopened it in 1861, building a smelter and stone cabins for a hundred miners, and operations expanded further after the transcontinental railroad reached the county in 1905. During World War I, Potosi served as an important source of zinc.
