Santiago Mill History

Santiago Mill is an increasingly rare example of an early- to mid-20th century American floatation mill located on National Forest System lands. Built in 1935, the mill was used for concentrating locally mined gold, silver and lead ore, utilizing the floatation process. It is one of the last complete depression-era mills standing.  The Santiago Mill is listed on the Colorado State Register of Historic Properties.
