This mine is located about a mile southwest of the town, in the upland prairie in the eastern part of section 12. When examined by Mr. Robertson in 1891, a shaft was sunk 60 feet in depth, and passed through a series of layers of limestone and chert until it reached the first opening at 50 feet. This opening was 5 to 8 feet high and was opened by a drift, which gradually widened away from the shaft, until a 40-foot face of ore was exhibited. The ore was composed of galena, filling seams and crevices in the broken chert. It was interbedded between the limestone (here dolomized) and chert layers. About 10 feet below was a second opening, of about three feet in height, in which large quantities of "silicate" were found.
Galena and calamine are the principal minerals. The calamine occurs in clusters of very delicate crystals, and some beautiful specimens have been obtained from this mine.
The country rock is the usual Lower Carboniferous limestone, with more or less chert. In and around the ore body, much of the limestone has been removed, and that which remains, in close vicinity of the ore, is altered to dolomite, becoming softer, darker, and having a decidedly different appearance from the ordinary limestone rock of the region.
