The Wolverine Mine was started as a small scale operation in 1882 and ceased in 1884. It was reoganized as the Wolverine Copper Mining Co. in 1889 and work began in 1890. The mine was absorbed by the Mohawk Mining Co. in 1923 and closed permanantly in 1925. The mine consisted of four shafts; #1 was abandoned early (it missed the lode). #2 was used to handle men and supplies. #3 was bottomed at approx. 4,000 ft. on the incline. #4 was bottomed at approx. 4,500 ft. on the incline. Being the Wolverine Mine sits between the Kearsarge Mines, and that it worked the Kearsarge lode, it has a wealth of minerals for the collector. Some of these include copper, silver, epidote, and quartz. Recently, agate nodules have been discovered encased within basalt on the rock piles.
