RICH NATIVE COPPER & CUPRITE: BIG CREEK MINE, CARBON COUNTY, WYOMING - VERY RARE
Item History & Price
| Reference Number: Avaluer:31665225 |
For your consideration is this very rare specimen from the Big Creek Pegmatite, Big Creek Pegmatite District, Carbon County, Wyoming USA. The Big Creek pegmatite was mined for copper from ~1940-1965 by Ralph Platt and others. It is an extremely unusual pegmatite in that it hosts copper mineralization including native copper, typically unheard of in a pegmatite. The pegmatite is otherwise mineralogically-simple, and is hosted in Archean metasedimentary rocks of the Archean Wyoming crato...n.
This is a hefty/solid, rope-like specimen of native copper with cuprite and malachite. I have never seen native copper from a pegmatite outside of this occurrence. Ex. Ralph Platt Collection. Collectible minerals of any kind are not common from Wyoming and this is a very unusual piece.
Specimen Dimensions: 6 x 1 x 1.2 cm. Weight: 17 grams
