<P> 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 . </P> <P> 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 . </P> <P> 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 . </P> <P> 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 metric tons) 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 metric tons) of silver . </P>
