General Notes
The IMA lists bindheimite as a species of questionable validity, although it has not been officially discredited (http://cnmnc.units.it/; accessed January 2023). Oxyplumboroméite was described as an IMA-approved species by Hålenius and Bosi (2013) and is closely similar, if not synonymous, with bindheimite.
Bindheimite was first recorded from Tsumeb by Pinch and Wilson (1977), with reference to a specimen in the collections of the Smithsonian Institution. They indicated that bindheimite "… occurs as a yellow alteration product of an unknown mineral in bladed masses several cm in size".
Bindheimite is not included, however, in the species lists provided by Keller (1984) and Lombaard et al. (1986) and Gebhard (1999) considered reports of bindheimite from Tsumeb to be questionable.
The occurrence of oxyplumboroméite at Tsumeb is listed by Von Bezing et al. (2014, 2016) who merely reiterate the description of Pinch and Wilson (1977) and appear to have treated oxyplumboroméite as completely synonymous with bindheimite.
Independently, oxyplumboroméite from Tsumeb has been reported by Joy Désor based on Raman and EDS identification (www.mindat.org/locentry-1310222.html; accessed April 2020). According to Désor oxyplumboroméite occurs as a pale yellow alteration product in tiny cavities in sulphide ore, associated with duftite, schultenite and wulfenite.
