The Camp Bird mine near Ouray, Colorado is one of the most classic of all the Colorado ore body localities. It is renowned for its superb Chalcopyrite specimens, exhibiting some of the finest twins for the species extant. This specimen features a few superb, sharp, splendent, metallic, brassy-gold colored twinned crystals of Chalcopyrite which are sitting atop contrasting white, prismatic Quartz crystals. There is also some brownish Sphalerite on the reverse side of the specimen. This is a superb Chalcopyrite from this most classic of San Juan localities. These specimens are impossible to obtain these days, and are regarded among Colorado collectors as some of the best from the state. This piece came to Rich Kosnar from his father-in-law, Dave Bergman. The exact location within the mine is Orphan #2 South East Orebody, 2100' level. Ex. Richard Kosnar Collection.
