New Jersey Zinc Mine, Elmo Mine
Ore was in solution breccias within carbonate rocks of the Ordovician Decorah and Galena Formations.
This zinc-lead mine is in the SE1/4SW1/4 sec. 2, T. 2 N., R. 1 W. The ore body was discovered by drilling by the Beloit-Elmo Mining Co. about 1908. A shaft was sunk to a depth of 100 feet in 1909, and the mine operated until about 1911, when it was closed because of high operating and pumping costs owing to inefficient equipment. In 1949, A. V. Austermann attempted to reopen the mine, but was unable to drain the water from it.
The ore body is of the gash-vein type and has a general N. 80° W. trend. It was mined about 400 feet east and 200 feet west from the shaft in the Prosser cherty member. The ore is pale yellow sphalerite, with very little iron sulfide, which occurs in disseminated and solution-breccia deposits in an opening along the mineralized joint. Galena locally accompanies the sphalerite.
The west heading of the mine is still in ore and is rich in galena, and the east heading is reported to contain a mineable face of disseminated sphalerite ore lean in marcasite.
