Rotherkopfite is a rare lead arsenic sulfide mineral first described from the Rotherkopf mine in Germany's Eifel volcanic region. It forms metallic gray prismatic crystals in hydrothermal polymetallic veins containing arsenopyrite, galena, and other sulfide phases. The mineral contributes to the mineralogy of Pb-As sulfide phases and is historically tied to classical German ore mineralogy.
