RI 4235 Bauxite Deposits in Union & Pontotoc Co., Miss.

"INTRODUCTION The district comprising Union, Lafayette, Pontotoc and Calhoun Counties, Miss. (fig. 1), was examined in October 1941 by R. W. Smith of the Bureau of Mines, accompanied by J. W. Adams of the Mississippi Bauxite Co. 3/ Subsequently, geologists of the Federal Geological Survey made a more detailed study of the area. 4/Bauxite had been reported as present in several localities in Pontot. County, and large deposits of kaolin are known in Pontotoc, Union, Calhoun, and Lafayette Counties. Many of the bauxite deposits, such as those on Big Hill, Second Hill, and Third Hill, in Pontotoc County, form the caps on hills and are outliers of Wilcox deposits on the Midway formation. Such deposits could have no extensions because of erosion and were not examined, as they were investigated by the Mississippi Geological Survey. 5/ Most of the bauxite was known to be low-grade, with a high iron content. However, Pontotoc County in particular presented possibilities of finding high-grade bauxite with a low iron content by drilling down the dip from the Wilcox-Midway contact. Consequently, with few exceptions the investigation was confined to drilling in this direction.Headquarters were established in Tupelo, Miss., on July 13, 1943, and mineral agreements were obtained covering 8,367 acres of land, with 62 land-owners in Pontotoc and Union Counties. Holes were drilled on properties of three of the landowners in Union County and 36 in Pontotoc County."
