Zinkenite is a steel-gray metallic sulfosalt mineral composed of lead antimony sulfide Pb₉Sb₂₂S₄₂. Zinkenite occurs as acicular needle-like crystals.^[1]

It was first described in 1826 for an occurrence in the Harz Mountains, Saxony-Anhalt, Germany and named after its discoverer, German mineralogist and mining geologist, (1790–1862).^[2]^[3]
