This company was one of the oldest in the vicinity. It was composed mainly of residents of the town of Rolla. The mine operated is less than a fourth of a mile NE. of the last, and is described as follows by Mr. Robertson: “The mine is in the prevailing limestone of this district, here quite coarsely crystalline, and carrying less inter-stratified chert than is common. The ore is almost entirely galena, occurring interbedded in the linestone, and at times partially filling the space left by the removal of that rock. The ore body appeared to be a run, having some times a vertical thickness of 20 to 30 feet, and a horizontal width as great as 100 feet. It has been followed in a direction a little north of east and south of west to the limits of the lot, or about 200 feet, but had been developed in lots adjoining to the east and west for over 1200 feet. While more or less of the ore occurred interbedded throughout the whole ore body, by far the largest part had been taken from abnormally developed portions resembling caves or pockets. Galena was the only mineral noticed. It occurred in the clay, often well crystallized, and always in modifications of the octahedron."
