Uchucchacuaite (AgMnPb3Sb5S12) is a rare sulfosalt mineral found in hydrothermal deposits.
It was first described in 1984 for an occurrence in the Uchucchacua Mine, Oyon Province, Lima Department, Peru and named for the mine.[2] It has also been reported from mines in Hokkaido, Japan.[2] It occurs with alabandite, galena, benavidesite, sphalerite, pyrite, pyrrhotite and arsenopyrite in the Peru deposit.[3]
