Central City-Idaho Springs District
Silver veins were discovered in the Central City-Idaho Springs district a short time after lode gold was discovered in 1859. However, mining the silver veins was delayed for the most part until smelters were built in the late 1860s. The veins of the district are zoned in a roughly concentric manner, with gold-bearing pyrite veins in the center, and silver-bearing galena veins more common in the outlying areas.
