Eureka began as a mining district with a few stakes claimed in 1864, but grew into a larger silver mining town by the 1870s. In 1873, Eureka became the seat of Eureka County, a new local government split of from Lander County to the west. Silver mining and milling continued in Eureka until the 1880s when the silver veins had been depleted. Limited ore discoveries in the district kept Eureka on the map. Gold discoveries in the Carlin Trend in the 1980s benefited Eureka County greatly, providing public revenue, although most of the workers lived in Elko County.
