Archaeologists from the Oriental Institute have discovered a gold-processing center along the middle Nile in the Sudan, an installation that produced the precious metal sometime between 2000 and 1500 B.C. The center, along with a cemetery they discovered, documents extensive control by the first sub-Saharan kingdom, the kingdom of Kush.

The team found more than 55 grinding stones made of granite-like gneiss along the Nile at the site of Hosh el-Guruf, about 225 miles north of Khartoum. The region also was known as Nubia in ancient times. Groups of similar grinding stones have been found on desert sites, mostly in Egypt, where they were used to grind ore to recover the precious metal. The ground ore was likely washed with water nearby to separate the gold flakes. “This large number of grinding stones and other tools used to crush and grind ore shows that the site was a center for organized gold production,” said Geoff Emberling, Director of the Oriental Institute Museum and a co-leader of the expedition. The research was funded by the National Geographic Society and the Packard Humanities Institute, which also offered to support all the other teams working in the Fourth Cataract salvage project, the location of the University’s expedition.

Do have a look at the site - there is lots more information and some good photographs.
