The Little Cottonwood district came into prominence in the 1870s with large ore shipments from the Emma Silver Mine, the Flagstaff Mine, the Emily Mine, and others. Silver ore was found in sandstone formations in the Silver Reef district in 1866, although large-scale mining operations did not begin until 1875. [38]
Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. Specific minerals include argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), polybasite (Ag, Cu) 16 Sb 2 S 11), and proustite (Ag 3 AsS 3). [2] Silver mainly occurs as a contaminant in chalcopyrite and galena, important ores of ...
The Crown Point-Belcher bonanza was discovered in 1870. The ore body extended from the 900 to the 1,500-foot level (275 to 460 m), having a length of 775 feet (236 m) and a width of 120 feet (37 m). The ore, the precious metal value of which was 54 percent from gold and 46 percent from silver, lasted only four years. [2]: 137–138
The patio process is a process for extracting silver from ore. Smelting, or refining, is most often necessary because silver is only infrequently found as a native element like some metals nobler than the redox couple 2 H + + 2 e − ⇌ H 2 (gold, mercury, ...). Instead, it is made up of a larger ore body.
As the Spanish need for silver increased, new innovations for more efficient extraction of silver were developed, such as the amalgamation method of using mercury to extract silver from ore. [ 6 ] In the two centuries that followed the discovery of Potosí in 1545, the Spanish silver mines in the Americas produced 40,000 tons of silver. [ 7 ]

Star City was established in 1861 when rich silver ore deposits were discovered in the area. During its height from 1864 to 1865 the town was home to 1,200 people. It also housed two hotels, three general stores, a Wells-Fargo office, a church and more than a dozen saloons.
