Donovan Mill tour
https://comstockfoundation.org/tours/After the world’s largest silver discovery in 1859, the Comstock Lode drew hordes of prospectors, miners and speculators who swarmed Virginia City, Gold Hill and Silver City. Although history does not always acknowledge it, Silver City soon became a milling town as well as a residents’ mining town throughout 1860-1870. Yet, over the last 150 years, about the only visible milling-days’ landmark left in town is the Donovan Mill, its outbuildings and large cyanide tanks at the south end of Main Street, which is also State Route 342.
