High Grade Gold-Silver Ore w/ Galena Freiberg Vein Cash Mine Gold Hill Colorado

Description

Here's a very rare specimen that was collected underground on the Freiberg vein at the famous Cash Mine in Boulder county Colorado by a geologist friend of mine.  The specimen consists primarily of galena, sphalerite and pyrite and I'm sure there are tellurides mixed in as well.  Very nice high grade specimen that is rarely seen on the market!
