The 1883 discovery of gold, silver, and lead in the Coeur d'Alene region of northern Idaho lured prospectors. The Inland Empire erupted with numerous mining rushes from 1883 to 1892. Mining and smelting emerged as a major stimulus to Spokane. At the onset of the initial 1883 gold rush in the nearby Coeur d'Alene mining district, Spokane became popular with prospectors, offering low prices on everything "from a horse to a frying pan". It would keep this status for subsequent rushes in the region due to its trade center status and accessibility to railroad infrastructure.
