Beautiful specimen of chalcopyrite in microcrystals deposited on a rich miniature of covellite crystals. This is extremely fine in quality for the locality which is even harder to come by than Butte material! It is not only attractive, but more importantly has freestanding blades of covellite, rather than the usual jumbled mess. 5.3 x 3.3 x 2.6
