Biehlite is a very rare mineral approved in 1999 and to date (May 2024) reported only from its type locality, the
Tsumeb Mine, Oshikoto Region, Namibia. Here it is a secondary
mineral found
associated with anglesite and
wulfenite on fine-grained copper ore
in the oxidation zone of the mine, in a
dolostone-hosted hydrothermal polymetallic ore deposit
(Mindat, Webmin, AM 86.197).
