Coryville (also spelled Coreyville) was laid out in 1883 after promising silver ore was discovered northeast of Corey Peak. A massive lixiviation mill costing $750,000 was erected by the Mount Cory Mining Company in 1884. Several houses were also built in Coryville, but despite intensive development, the camp folded before the end of the decade. The mill closed in 1887, and was dismantled in 1890.
