SILVER MINING
Silver mining in the United States part4
Article # : silver178
Nevada
The discovery of the Comstock Lode in 1858 inaugurated large-scale silver mining in the United States. 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).
New Hampshire
Silver-bearing galena was mined from three districts in New Hampshire.
The Silver Lake mine near Madison in Carroll County operated intermittently from 1826 to 1918. Ore was extracted from underground workings until 1915, when a small open pit was dug.
The Mascot mine and the Shelburne mine worked veins in schist and granite on Mount Hayes, between Gorham and Shelburne in Coos County. The Shelburne mine operated intermittently from the 1830s into the 1850s; a final attempt at mining took place in 1880. The Mascot mine worked from 1881-1885 and in 1906.
The North Woodstock mine, near the town of the same name in Grafton County, apparently mined and milled lead-silver ore, although no production records are known.
New Mexico
No silver is known to have been mined in New Mexico prior to the silver discovery in 1863 near Magdalena in Socorro County. The major silver-mining area of Silver City in Grant County was discovered in 1866.
A rancher found the Lake Valley silver deposits in Sierra County in 1876. The deposits are bedded manto-type deposits in Paleozoic limestone. The mines, promoted by Whitaker Wright, produced well for a few years after miners tunneled into a silver-lined cavity they named the “bridal chamber” that alone yielded 2.5 million troy ounces (78 tonnes) of silver. But no more bridal chambers were discovered, the mines struggled and were worked periodically into the 20th century. The district produced manganese during World Wars I and II. Total production of the Lake Valley district through 1931 was 5.8 million ounces (180 tonnes) of silver.
Almost all the silver produced today in New Mexico comes as a byproduct from the two large open-pit copper mines in southwest New Mexico.
Oklahoma
Copper and silver occur in a sandstone roll-front-type deposit in the Wellington sandstone of Permian age at Paoli, Garvin County, Oklahoma. About 1900, several wagon loads of ore were shipped from the deposit.
