· Landforms termed "waste heaps", "dumps" or "spoil" were, for example, associated with mining on the broad floor of the Wadi Khalid. These were reported to contain fragments of copper-rich ores and occasional rock-anvils and hammer-stones ( Hauptmann, 2000, Hauptmann, 2007, 46, 116–121; Hunt and el-Rishi, 2011, Weisburger, 2006 ).
