Wildly iridescent chalcopyrite in shades of blue and purple inter-grown with brassy pyrite and mounded over cubic galena. The chalcopyrite was formed in ball like mounds first and then partially replaced by pyrite. This was collected from a unique pocket in 2013: it is unknown at this point if this type of combination will be found again in the stope. In great condition.
