This mine is located near the Meramec Springs, seven miles southeast of St. James. The main workings consisted of a circular pit 225 feet in diameter and 80 feet deep, the top of which occurs near the contact of the Roubidoux and Gasconade formations. The enclosing sink structure is well outlined on the east, north, and west by steeply dipping ledges of sandstone and the ore body was enclosed by steeply dipping beds of the same material. According to the Tenth Census Report, a horse of clay occurred in the center of the deposit near the surface. Near the bottom of the pit this mound of clay was underlain by soft red hematite, which has been removed as far as safety would permit. It is reported that the bottom of the pit is still in ore at the 80 feet level, below which a shaft sunk an additional 40 feet, passed through the ore into clays and sand at a depth of about 20 feet.
The ore consisted of soft red and specular hematites, an average sample of which ran 68.06% iron, 2.06% silica, 0.040% Phos., and 0.00% Sul. Samples of the red ore alone showed 60.76% iron, 9.78% silica, 0.051% Phos., 0.126% Sul., and 0.00% Mn.
This mine was operated intermittently from 1826 to 1891, producing a total of about 375,000 tons of ore.
