near Eureka. The metal content of ore was increased through the process to make transportation less expensive. The reducing process used was an acid-brine chloridizing and leaching process which became outdated, leading to the abandonment of the site in 1925. At the mill's highest productivity it processed 200 tons of ore daily from the Tintic Mining District. What remains of the mill are foundations for water tanks, crushers, roasters, iron boxes, leaching tanks, and drain boxes. The site dominates the surrounding landscape with its size and unique colors and shapes. It has been speculated that the mill may be the contributor of heavy metal pollution in the Warm Springs which lie below it. It was listed on the
