Ahmeek mine, Ahmeek, Keweenaw Co., Michigan, USA

Ref.: Rocks & Min.:58:111, U.S.G.S. PP 144, "The Hard Rock Mining Era", by Kilpela.

The Ahmeek Mining Company was organized in 1880 as an exploration wing of the Seneca Mining Co. to work the Kearsarge Conglomerate lode. The original operations consisted of two shallow shafts, but production was irregular at best. In 1903, with the discovery of the Kearsarge Amygdaloid lode, the Ahmeek Mining Co became it's own operation. The new workings consisted of four inclined shafts that worked to a depth of approx. 3,000 ft. Two of the shafts, 3 and 4, were unique in that both were serviced from a common shafthouse. In 1923, the company merges with C&H and operations were suspended in 1931. After the depression ended the mine reopened in 1936 and continued until about 1966 when the mine closed permanently.
This is a great site for the collector. Some of the minerals found here include copper, silver, datolite, nice calcite crystals, and the ever popular domeykite.
