This mine is near the village of Raum in Pope County, Illinois.

Bain (1905) reported that the Pittsburg Mining Company had sunk two shallow shafts and a tunnel into the local limestone, which Weller et al. (1952) later identified as the Kincaid Formation (Bain [1905] believed the relative age of this limestone unit was the same as the St. Louis Limestone]).

The Kincaid Limestone on site outcropped in a belt about 200 feet wide, with a general strike of N. 35° E., and was traceable for several miles. Bain (1905) observed thin veinlets of galena and sphalerite, which cemented in a breccia with fluorite and calcite. The Pittsburg Mining Company also erected a mill and operated the site until the 1930s (Bain, 1905, Weller et al., 1952).

During the 1860s, a local pit close to the mine shafts produced blueish to white clay for the purpose of ceramic pottery and stoneware. Bain (1905) hypothesized that this clay was kaolinite, while Weller et al. (1952) later amended the clay as halloysite. The locals called this pit the “Clay diggings.”
