Peacock Ore is a commercial name that is used to describe both iridescent Bornite and Chalcopyrite.
Major Bornite deposits are in located in Australia (Tasmania), Austria, Canada, Chile, Great Britain, Kazakhstan, Morocco, Peru, and the United States (Arizona, Connecticut, Montana and Utah).
Major Chalcopyrite deposits are located in Australia (Tasmania), Canada, China, Germany, Great Britain, Japan, Peru, Spain, and the United Sates (Arizona, Colorado, and Utah).
Sulfide minerals such as Bornite and Chalcopyrite are ore minerals for valuable metals including Gold, Silver, Platinum, and Copper. These are often mined in massive open-pit industrial Copper mines, where the ore minerals are crushed and melted to extract the metal. Occasionally these sulfide minerals may be found in small-scale or artisanal deposits. Depending on the circumstances, it may be economically worthwhile for the miners to sell the Bornite or Chalcopyrite in their natural form. If the minerals are tarnished, naturally or artificially, they are then sold under the name “Peacock Ore.”
