Lost Louisiana Mine

The Lost Louisiana Mine is an American legend about buried Spanish treasure that has been sought since the Victorian era, primarily in Arkansas’s Ouachita and Ozark mountains regions. The legend’s core narrative is that a Spanish expedition concealed a rich gold mine in the wilderness of Spain’s Luisiana colony (hence the name), and in returning to New Orleans, all but one of the party was killed by Indians. In the early twentieth century, variants of the legend attributed the treasure to either Freemasons or Sephardic Jews exiled from Spain who brought a fortune in gold and jewels with them, or a Catholic or Aztec trove brought from Spanish Mexico. Such Spanish treasure legends were once part of a deeply anti-Spanish …

Manganese Mining

The mining of manganese ore was a very important economic activity in Arkansas between 1849 and 1959. The region around Batesville (Independence County)—including about 100 square miles located in northwestern Independence County, southeastern Izard County, and northeastern Stone County—has produced more than ninety-eight percent of the manganese ore shipped from Arkansas. A second area including portions of Polk and Montgomery counties also contains manganese ores. The first commercial exploitation of manganese was by Colonel Matthew Martin. Between 1848 and 1850, Martin purchased large tracts of land containing the ore, and, between 1850 and 1852, he shipped small quantities of manganese from Penter’s Bluff (Izard County) on the White River to Boston, New York, Philadelphia, and even Liverpool, England, where it …

Mercury Mining

aka: Cinnabar Mining
Mercury, which was first mined in Arkansas in 1931, is in most rock types in trace amounts, generally occurring at higher levels in shale and clay-rich sediments and organic materials like coal than in sandstone, limestone, or dolostone. Although mercury was widely used in the past for several applications, the market for products containing mercury steadily declined in the 1980s because it was recognized to be toxic. It still has important uses, however, in the chemical and electrical industries as well as in dental applications and measuring and control devices. The mercury-bearing district in southwest Arkansas occupies an area six miles wide by thirty miles long, extending from eastern Howard County through Pike County and into western Clark County. Surface …

Mining

Mining is defined as the extraction of valuable minerals or stone (mineral resources) from the earth, usually from an ore body, vein, or bed. Materials mined in Arkansas include base metals, iron, vanadium, coal, diamonds, crushed and dimension stone, barite, tripoli, quartz crystal, gypsum, chalk, and bauxite. Mineral resources are non-renewable, unlike agricultural products or factory-produced materials. Mining in a wider sense includes extraction of any non-renewable resource, including petroleum, natural gas, bromine brine, or even water. These resources are recovered by extractive methods that differ from those of normal surface or underground “hard rock” mining methods. Early settlers in the Arkansas Territory used several local mineral commodities. These included galena (lead ore), hematite and goethite (brown iron ores), saline …

Quartz Mining

Arkansas is one of a small number of places in the world with enough quartz crystals to justify commercial mining. Though the amount of unmined quartz in the state is not yet known, Arkansas does have, in terms of both size and quality, some world-class deposits of quartz. Quartz is a common mineral that becomes crystallized under extreme geologic pressure. These crystals have been used to make oscillators for radios, computer chips, and clocks. Quartz crystals are also valued for their beauty as mineral specimens and gemstones. In 1967, the General Assembly adopted the quartz crystal as the Arkansas State Mineral. History of Quartz in Arkansas A quartz arrowhead that is estimated to be over 11,000 years old was discovered …

Saltpeter Mining

Potassium nitrate, or saltpeter, is a naturally occurring mineral that is vital to the production of gunpowder. Found in limestone caves in the Arkansas Ozarks, it became one of the state’s most important chemical industries during the Civil War due to the Confederacy’s demand for arms. Although this resource was a definite advantage for the Confederacy, problems with labor, security, and transportation made Arkansas’s saltpeter mines an ultimate failure. Saltpeter deposits were known by early Arkansas settlers long before the Civil War in Madison, Searcy, Independence, Marion, and Newton counties. A geographical survey was conducted by Dale David Owens from 1857 to 1860. His findings were published in 1860, and, by 1862, the Confederacy, looking to arm itself for the …

Sand and Gravel Mining

aka: Gravel and Sand Mining
Sand is usually defined as an accumulation of mineral grains in sizes ranging from one-sixteenth to two millimeters. Sand normally consists predominantly of quartz grains of variable degrees of roundness. Other mineral grains within the sand size range are also present and typically consist of feldspar, chert, ilmenite, and other less abundant resistant minerals. Gravel is considered to be an unconsolidated mixture of rock fragments, pebbles, cobbles, and boulders of indefinite size, but always larger than sand-sized materials. Gravel normally consists of a mixture of rock types, depending upon the original source, and may consist of various quartz rock varieties, such as chert, sandstone, novaculite, agate, and milky vein quartz, as well as limestone, dolostone, and other resistant rock types. …

Silver Mining

The silver in Arkansas is mixed sulfide ores of lead, zinc, copper, and antimony in small, scattered deposits in parts of the southern and eastern Ouachita Mountains. Most of the known mining activity involving silver took place between 1840 and 1927 and rarely resulted in profit to owners and operators. Sale of claims or mines to unsuspecting investors was usually the only route to profit. The mines opened in the 1800s were shallow, reaching maximum depths of less than 200 feet. Most of the deposits where mining was undertaken are clustered in three groups. One is along Kellogg Creek in Pulaski County, north of the Arkansas River. Deposits in another group were clustered along tributaries near the confluence of the north …

Tripoli Mining

Tripoli is a microcrystalline form of quartz (SiO2) that is derived by the alteration of chert, chalcedony, or novaculite, or leaching of highly siliceous limestones. The removal of carbonate is essential to the formation of Arkansas tripoli. Tripoli is present in three general areas of Arkansas: northwestern Arkansas near Rogers (Benton County), in the Ouachita Mountains near Hot Springs (Garland County), and near Athens (Howard County). Tripoli has varied uses. Due to its inert nature and its fine-grained texture, tripoli has numerous applications, mainly as an abrasive in polishing, buffing, and burnishing compounds; in scouring soaps and powders; a filler or extender in plastics, rubber, and sealants like caulks and epoxy resins; and a pigment in paints. It also improves …

United Mine Workers of America (UMWA)

The United Mine Workers of America (UMWA) was at one time the most powerful union in the United States. The union, which remains active in the twenty-first century, encouraged the development of the Arkansas State Federation of Labor. The UMWA was formed in 1890 in Columbus, Ohio, when Knights of Labor Trade Assembly No. 135 merged with the National Progressive Union of Miners and Mine Laborers. This combined union banned discrimination against any members based on race, national origin, or religion. By 1898, the UMWA had achieved improvements in wages and hours per week with mine operators in Pennsylvania, Ohio, Indiana, and Illinois. In 1898, the UMWA began organizing miners in western Arkansas. Arkansas became a part of District 21, and …

Vanadium Mining

Major deposits of vanadium were discovered in central Arkansas by Union Carbide’s Western Exploration Group in the 1960s. Vanadium orebodies are found in two isolated igneous intrusive complexes in the Ouachita Mountains of Arkansas: the Potash Sulphur Springs (now Wilson Springs) complex located in Garland County and the Magnet Cove complex in Hot Spring County. The Wilson Springs vanadium deposits were the first to be mined solely for vanadium in the United States. The major use of vanadium is as an alloying metal in iron and steel (ferroalloy). Small amounts of vanadium added to iron and steel significantly increase its strength, improve toughness and ductility, and reduce weight, making it suitable for structural and pipeline steel. Vanadium also increases high-temperature …

Washington Monument Marble Quarry

In 1833, the Washington National Monument Society was founded to create a memorial to the United States’ first president, George Washington. A year before a design contest for the memorial was announced, the society laid down guidelines: “Its material is intended to be wholly American, and to be of marble or granite brought from each State, that each State may participate in the glory of contributing in material as well as in funds to its construction.” Arkansas would ultimately donate three stone slabs to the Washington Monument in Washington DC, which was constructed intermittently from 1848 to 1888. The first stone, representing the state of Arkansas, was taken from a mountain in what was then Carroll County (now Newton County) …
