Localities

At the type locality, the Asis West sector, Kombat Mine, Kombat, Grootfontein, Otjozondjupa Region, Namibia, damaraite occurs in a late-stage vein cutting a banded manganese ore lens in copper-lead-silver ores formed by hydrothermal and metasomatic replacement of dolostone (HOM). The vein is a baryte-calcite-jacobsite-hematite vein, in which damaraite is also associated with hausmannite, hematophanite, native copper and a lead molybdenum oxychloride. The assemblage occurs in a manganese ore lens (AM 77.671). Other associated minerals include defernite, crednerite, asisite, andradite, vesuvianite, calcite and baryte (HOM).
