Localities

At the Bou Azzer mining district, Drâa-Tafilalet Region, Morocco, schneiderhöhnite is associated with löllingite, karibibite, eosphorite, arseniosiderite, scorodite and quartz (HOM).
Schneiderhöhnite has been found in quartz-lined cavities in löllingite as crystals to 1 mm. The most commonly observed formation sequence is quartzschneiderhöhnitekaribibiteparasymplesite (Minrec 38.5.394).

At the type locality, the Tsumeb mine, Tsumeb, Oshikoto Region, Namibia, schneiderhöhnite is a rare secondary mineral in an oxidation zone in the dolostone-hosted hydrothermal polymetallic ore deposit. Associated minerals include zincian stottite, chalcocite, tennantite and leiteite (AM 59.1139, HOM).
