Gold-bearing quartz vein-type and volcanogenic massive sulphide (VMS) mineralization, hosted in volcanic rocks of the Proterozoic Ariab formation. The oxidation zone is well developed and enriched in gold so as to form a gold deposit on its own.

Started in 1992 as Sudan's first modern gold mine.
12 pits have been mined over the years.

Located about 200 km west of Port Sudan.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

ID: 1383627
Neoproterozoic intrusive and metamorphic terranes

Age: Neoproterozoic (541 - 1000 Ma)

Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.

Lithology: Intrusive and metamorphic terranes
