Cardinal was founded in 1870 when Sam Conger and his partner discovered the Boulder County Mine on the eastern end of the same vein as the Caribou Mine. This vein contained rich deposits of gold and silver. The population of Cardinal grew from 200 people in 1872 to over 1,500 people during its peak between 1878 and 1883. The mill was built to process ore from local mines. Most of the area's silver mines closed after the crash of the silver market in 1893, and the town was almost deserted. The Boulder County Mine was one of the few mines in the area that continued to operate until 1899. In 1905 a rail line to the gold camp of Eldora was built, passing close to Cardinal. This brought new life to the area and to the mill for a short time. The Boulder County Mining Company used the Cardinal mill to process tungsten from 1915-1917.Rights management statement available at: http://library.mines.edu/digital/rights.htmlGold ore processing plantsSilver ore processing plantsTungsten ore processing plantsStillImage
