An underground copper mine consisting of two shafts located near Allouez, just north of Calumet. The Allouez Mining Co. was organized in 1859, but work didn't start until 1869 on the Allouez Conglomerate lode. Work continued until 1877, when it was leased on tribute until the company resumed control in 1880. In 1885 the mine was again leased to tributers until 1889 when the company resumed control. In 1923, the Allouez Mining Co. was absorbed by C&H and mining operations ceased shortly after. Minerals that can be found here include copper, silver, cuprite, malachite, and some nice chrysocolla.
