Silver mining was a driving force in the settlement of western North America, [28] with major booms for silver and associated minerals (lead, mostly) in the galena ore silver is most commonly found in. Notable silver rushes were in Colorado; Nevada; Cobalt, Ontario; California and the Kootenay region of British Columbia; notably in the Boundary ...
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 is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal.
Mizpah mine, Tonopah. The last great silver-mining district to be developed in Nevada was Tonopah, in Nye County, discovered in 1900. The silver deposits are replacement veins in Tertiary volcanic rocks. Through 1921, the district produced 138 million troy ounces (4,300 metric tons) of silver and 1.5 million ounces (47 metric tons) of gold.
Bonner Shaft, Gould & Curry Mine, 1874. The ore was first extracted through surface diggings, but these were quickly exhausted and miners had to tunnel underground to reach ore bodies. Unlike most silver ore deposits, which occur in long thin veins, those of the Comstock Lode occurred in discrete masses often hundreds of feet thick.
The Creede district in Mineral County was discovered in 1887 but did not become a significant silver producer until 1891. The ore occurs as veins along north–south trending faults, and as replacement bodies in the Creede Formation, a Tertiary ash-flow tuff. Ore minerals are sphalerite, galena, acanthite, native silver, pyrite, and ...
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. [5]Galena is one of the most abundant and widely distributed sulfide minerals.
