Location, SW1/4 of NW1/4 Sec. 7, T. 11N., R.17E. The Mayville Shaft Mine is a shaft iron mine that produced, by far the most iron of all the mines in the Iron Ridge District/Neda Iron District. The 3 main shafts sunk at the site go 140 feet down through 16 feet of glacial drift, and 98 feet of dolomitic limestone, to reach the 26 foot deep ore body. The mine operated from 1911 to 1928, though surface cuts were being worked upon at the site since 1849. During the time the mine was active, the mine produced 2,156,939 gross tons of high grade ore, test surveys on ore samples reported 43 to 47 pecent iron in the ores, though some other iron ores mined at the site had more or less iron in thier composition. During mining, groundwater seeped into the tunnels and required the use of four pumps working day in and day out to keep the mine from becoming waterlogged. After the mine was abandoned , groundwater seeped up and completely flooded the mine and the water level rose only 30 feet from the shaft collar. Eventually 3 concrete caps were erected to seal the 3 main shafts. The mine site is now on private property and collecting at or near the site is not possible.
