Cubo-octahedral Sperrylite crystals, a rare platinum arsenide much desired by collectors. The crystals, which have very well-balanced faces of the cube and octahedron, are well-defined, very bright, and on a Chalcopyrite matrix.
Talnakh forms part of the Noril’sk–Talnakh metallogenic district, one of the largest magmatic Ni–Cu–PGE sulfide complexes in the world. The mineralizations are associated with mafic–ultramafic intrusions related to Siberian Traps magmatism (Permian–Triassic), emplaced within the Putoran Plateau. The sulfides are concentrated in massive and disseminated bodies, with typical species such as Chalcopyrite, Pentlandite, and Pyrrhotite, together with numerous platinum-group minerals, notably Sperrylite.
