The Caribou Mill was built in 1870-1871 by A. D. Breed and sold to the Mining Company Nederland in 1873. Silver ore was transported by wagon from the Caribou Mine to the Mill. The mill had five levels. Ore was unloaded and crushed at the uppermost level. The stamp room on the next level down pulverized the ore before it was moved down another level to the cylinder room where the ore was roasted. On the fourth level the ore went to the amalgamating room. The bottom level held the melting room where the amalgamated silver was taken for retorting and melting into bars. The mill, when running at full capacity, could handle twenty tons of ore per day, but the crash of the silver market in 1893 led to its closure. Sometime in the early 1900s, the mill was reopened to process tungsten ore and renamed the Wolf Tongue Mill.
