It crystallizes in the hexagonal crystal system (space group P-62c).
Key properties: Mohs hardness 5; specific gravity 9.33.
IMA symbol Mjk, IMA status: approved, named in 1974.
Occurs as intergrowths with other platinum-group minerals in chalcopyrite and talnakhite ores (Majak mine, Russia); in sulfide mineralization in a strongly metamorphosed layered intrusive (Konttijärvi intrusion, Finland).
It is found associated with Chalcopyrite, talnakhite, polarite, stanopalladinite, silver, ferroplatinum, sperrylite, other platinum-group minerals (Majak mine, Russia); isomertieite.
The name refers to the Majak (Mayak) mine, Russia.
