M261: Copper Specimen. Locality: Ray Mine, Arizona. Selection: Rough Specimen.
Appearance: This unique specimen is from the Ray Mine. The Ray Mine, located in Pinal County Arizona. Opened in 1880 and has produced roughly 62 million pounds of copper. We believe this awesome specimen could be post mine creation, meaning that it may have formed in the mine dump around a pipe or a stick in the dump as it has a deep 1/2″ hole running almost the entire length of the specimen. Great item for any collection.
Approximate measurements: LxWxH – 3 3/8″ x 2 1/8″ x 2″.
Availability: single specimen, exclusive.
