CUBANITE (Copper Iron Sulfide) - Amethyst Galleries

Cubanite (also known as "chalmersite") is a rare copper mineral that does not contribute much to the supply of copper.It would not even be considered an ore of copper except that it is often interbedded with other ores of copper and so it does contribute some copper when these other ores, such as chalcopyrite, are processed.Cubanite is also associated with gold in some gold mines.
