Eskebornite is a selenide mineral with the formula CuFeSe2.[2][3] It crystallizes in the tetragonal system and it has a brassy colour. Eskebornite is sometimes found as thick tabular crystals, but is more often found intergrown with other selenides.[4] It is part of the chalcopyrite group and forms a series with chalcopyrite.[5]
