Antimony mine areas refer to regions with favorable geological conditions for antimony ore extraction. Antimony ores primarily exist in two forms: sulfides and oxides. Their distribution is closely related to geological structures, often found in areas with active tectonic activities such as seismic zones, fault zones, and volcanic belts ( Chen ...
Mined ore deposits occurred as lenses or pockets of stibnite encased in nearly vertical quartz veins. Antimony mining took place intermittently in Arkansas after the metal's discovery in 1873. Smelting attempts were made first in 1887 but were unsuccessful. The first commercial production was recorded in 1889.

Mining for both gold and antimony began at the Stibnite Mine in 1931. A body of rich tungsten ore was also found and mined. During World War II, Stibnite produced ninety-eight percent of America's antimony in addition to a large proportion of the nation's tungsten. Both metals were vital to the production of military machinery and weaponry.
