Silver mining in Nevada
Silver mining in Nevada, a state of the United States, began in 1858 with the discovery of the Comstock Lode, the first major silver-mining district in the United States. Nevada calls itself the "Silver State." In 2006, Nevada was the nation's second-largest producer of silver, after Alaska.()

==Comstock Lode==
(詳細はComstock Lode had been a minor gold placer district since 1849. In 1859, several prospectors discovered its rich lode silver ore, and a great rush of miners poured eastward from California, and established Gold Hill and Virginia City, the principal towns of the Comstock Lode.〔Francis Church Lincoln (1923) ''Mining Districts and Mineral Resources of Nevada'', reprinted 1982, Las Vegas: Nevada Publications, p.222-233.〕 The district has been mostly inactive since the 1920s.
The Comstock was the first important silver-mining district in the United States, and its discovery stimulated a great deal of prospecting for silver across the Great Basin area of the United States. The resulting silver rush led to many other silver discoveries in Nevada, including Austin (1862), Eureka (1864), and Pioche (1869).
