Native Copper Bingham Canyon Mine, Bingham District, Oquirrh Mts, Salt Lake Co., Utah 12.3cm x 6.45cm x 3.5cm Ex. A. E. Seaman Mineral Museum No. DM-1932

Description/Interesting Notes: A unique, old time example of native copper from Utah!!! This specimen is comprised almost entirely of native silver in association with a small amount of matrix!!! The native copper is completely crystalline - consisting of a dense group of bright, intergrown copper crystals that has been infiltrated by a second generation of thin, wire-like dendritic copper crystals that have a distinctly different and darker patina!!! In person, the difference between the two generations of intergrown copper crystals is quite pronounced!!! This specimen is fascinating upon close inspection!!! A fantastic old time native copper from Utah!!! This specimen retains an old label from the A.E. Seaman Mineral Museum as well!!!
