Environments
Although schaurteite was known as early as 1967, to date (September 2025) it has been reported only from
the type locality.
Localities
At the type locality, the Tsumeb Mine, Tsumeb, Oshikoto Region, Namibia, schaurteite occurs as needlelike
crystals; it is a secondary mineral formed in the oxidised
zone of a dolostone-hosted hydrothermal polymetallic ore deposit.
Germanite is an associated mineral
(Mindat).
