(1995) report that namibite occurs associated with schumacherite, eulytite (?), pucherite (?), mrazekite and chrysocolla from a skarn on the western side of a gorge on Morass Creek, north of Benambra, Victoria, Australia.
(1994) report an occurrence of namibite from the Elias mine, Jachymov, Krusne hory, Czech Republic, where it is found in fragments of quartz gangue with eulytite, beyerite, bismutite and pucherite. The namibite here is dark green with an anhedral to subhedral habit.
It is found in quartz cavities associated with native bismuth, beyerite, bismite, bismutite, clinobisvanite pseudomorphs after pucherite, and other oxidized Cu minerals.
