Most all the buildings are left standing. Mexicans first worked the Salero mine in the 18th century. Salero, meaning salt cellar, was acquired by the Salero Mining company in 1857 who's company headquarters were in Tubac. All of the men who originally founded the company were later killed by Apaches. George Clark later relocated the mine in 1870 and the post office was established 14 years later.
Today there are many well preserved buildings left but the whole town site is on private property.
