Now, as of 2017, it costs cents (it cost cents in 2012). That's good news for a decline in cost, but, it still means a heavy burden to make the little onecent coin. This is more than 2x production cost over a very short amount of time.

These costs are derived from the Advanced projects, research and development and Exploration amounts presented in the Condensed Consolidated Statements of Operations less the amount attributable to the production of copper at our Phoenix and Boddington mines.
