Cuprite Plus from Red Dome Mine QLD
Cuprite, commonly known as red copper ore is a copper and oxygen mineral. This specimen has a coating of Malachite which is a common mineral association. Other specimens displaying bright cherry-red Cuprite crystals have also come from the Red Dome Mine where this specimen was mined many years ago.
The Red Dome Mine site operated from about 1986 to 1997, producing approximately 1 million ounces of gold, 35,000 tonnes of copper from about 15 million tonnes of ore.
I intend to add a specimen of museum grade Cuprite to the collection to show the transparent red crystals it forms. Currently I have only seen it with associated malachite coating.
I acquired this specimen from Greg at Blue Gems at the October 2013 Central Coast Gem Festival.
