[3] Evidence suggests that Nubia had sporadic access to gold nuggets during the Neolithic and Prehistoric Period. During the Bronze Age, sites in the Eastern Desert became a great source of goldmining for nomadic Nubians, who used "twohandmallets" and "grinding ore extraction ." By the Old Kingdom, the oval mallet was introduced for mining.
