A review of gold occurrences in the Northern and Central Zones of the Damara Orogen and the underlying mid-Proterozoic basement, central Namibia
Historically, late Proterozoic/early Palaeozoic Pan-African terranes have never been large producers of gold. The discovery of Damaran carbonate- and skarn-hosted gold mineralisation in the Karibib District in the 1980s came as a major surprise and the Navachab Gold Mine (10.4 million tonnes at ~2.4 g/t Au; annual production of approximately 1800 kg of gold) was opened in 1989. Further exploration in central Namibia has subsequently revealed that the underlying mid-Proterozoic basement, Damaran mafic volcanic rocks and turbidite sequences are also prospective for gold. This paper presents a geological and geochemical data base that has been compiled for gold occurrences in the Northern and Central Zones of the Damara Orogen with particular reference to mineralisation in the Usakos-Karibib-Omaruru area.
