Abstract
The DuBois fluorite property in the southwestern part of Hardin County, Ill., has been active intermittently since 1904 and has produced an estimated total of 1,000 to 2,000 tons. The persistence of the vein and the stratigraphy suggested extensions of the ore body formerly mined. The Bureau of Mines investigated the property by core drilling early in 1944. Four holes were bored which totaled 1,106 feet and extended along a strike length of 1,150 feet. The data obtained in the course of the investigation are presented in this report.
