Sparkly, robin's-egg blue aurichalcite lathes richly cover both sides of the sturdy gossan cabinet matrix on this fine and rare old-time specimen from a very uncommon Montana locale - the Cleopatra Mine in Beaverhead County. Comes with a faded, hand annotated label with a March 1944 date. Ex. Dennis Mullane Collection. I have never seen a specimen from this locality, to be honest. The Mullane collection incorporated an earlier collection of a newspaperman from Butte named Kessler, though, and he had a huge range of early 1900s minerals from obscure (today) western localities.
