Barites high density and chemical inertness make it an ideal mineral for many applications. The chemical formula for barite is BaSO 4. To be economically viable for extraction, barite usually needs to be the predominant material in a deposit. The types of deposits in which it is normally found include vein, residual, and bedded.
Production of barite from Arkansas was used exclusively as a weighting agent in drilling muds in the oil and gas industry, due to its relatively high specific gravity 4.5. World class barite deposits contained within the Stanley Shale Mississippian are present in the Ouachita Mountains province of Arkansas, specifically in Hot Spring, Montgomery, and Polk Counties. Production was mainly by National Lead Division of Baroid Company and Magnet Cove Barium Corporation Magcobar.
In 1981, the cost of extracting and processing barite ore exceeded the product39s value because the nation began importing ore from less expensive over-seas sources. Most of the barite mining operations in the United States ceased.
Reserves of barite in Arkansas are estimated to be in the order of millions of tons, but further mining awaits barite39s expanded use. Increased domestic oil-field drilling activities and a shortage of cheap foreign ores could make Arkansas barite a viable mineral commodity again.
Due to interest, AGS staff began electronic preservation of these paper documents, starting with scanning 153 maps, drill core cross sections with ore intecepts, ore removal schedules, and geologic maps. A second phase of scanning resulted in digital availability of all the drilling logs for the Milchem exploration holes, and core sample analyses, and calculated ore grades.
Barite is classified based on its purity, i.e. the concentration of barium sulfate present in barite. Accordingly, the specific gravity of barite varies. Barite with specific gravity of 3.9 gcm3 or less falls under the up to Sp. Gr. 3.9 grade segment. The Sp. Gr. 4.0 segment comprises barite with specific gravity of 4.0 gcm3. Sp.
Core from the Milchem exploration project of Fancy Hill and Gap Mountain deposits is available for visual examination at the Norman F. Williams Well Sample Library during normal working hours.

The earliest published work on the Fancy Hill and Gap Mountain barite deposits of Montgomery County was by R. B. McElwaine of the USBM in 1946. This report was followed by a more general 3 county report by T. A. Jones, USBM, in 1948. A later report covering all of the known barite deposits in Arkansas was published in 1958 by B. J. Scull as Information Circular 18 by the Arkansas Geology and Conservation Commission, a predecessor of the Arkansas Geological Survey AGS.
A renewed recent interest in the Arkansas barite deposits is partly due to increased drilling in the USA, combined with China39s increasing domestic consumption of barite and stated policy to begin a reduction of the export of barite exports. These economic developments have drawn commercial interests by mining and development companies to the Fancy Hill deposit.
