Very rare. Questionable status at Tsumeb.
Paragenetic and General Notes
Listed by both Lombaard et al. (1986) and Gebhard (1999) as a questionable occurrence at Tsumeb. However, Gebhard (op. cit.) suggests that romanèchite is one of the component minerals in the black, manganese oxide coatings sometimes observed on calcite and mottramite.
