Silver mining in Colorado. Silver mining in Colorado has taken place since the 1860s. In the past, Colorado called itself the Silver state. (Nevada also calls itself the Silver state. Idaho, however, actually produces the most silver in the US.)
In 1858 the great silver rush began in Napa Valley, and miners eagerly flocked to the eastern hills. In the 1860s, mining carried on, in a large scale, with quicksilver mines operating in many areas of Napa County. The most noted mine was the Silverado Mine, near the summit of Mount Saint Helena.
