A database available at (Wise Uranium, 2012) provides overnight construction, annual operating and decommissioning costs for over two dozen operating and proposed uranium mining and milling projects. To illustrate uranium production cost calculations, data sets for three projects have been selected from the (Wise Uranium, 2012) database. They are: a generic Colorado Plateau mine (underground, UG) with ore processing at the White Mesa mill; the Areva Trekkopje (open pit, OP) mine and mill in Namibia; the Lost Creek (in-situ leaching, ISL) project in Wyoming.
