Mining of antimony ore has been limited to northern Sevier County, although some stibnite is also present in Pike County, associated with cinnabar (HgS). 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 ...

However, it is often the primary focus of extraction in gold–antimony vein mining operations. The inclusion of antimony in gold ore poses challenges in terms of processing, leading to increased difficulty and cost. Consequently, it may be necessary to accumulate a quantity of gold ore with a significant antimony content [3,9].
