Rare. Very rare in the upper levels of the mine; most specimen material is from the second oxidation zone.
- 1st Oxidation Zone
- 2nd Oxidation Zone
A small vug in the second oxidation zone, discovered in the early 1980s, contained crystals of beudantite (to 5 mm) on lepidocrocite (Gebhard, 1999).
Paragenetic and General Notes
Gutzmer and Cairncross (2001) described germanium-rich beudantite containing up to 6.5% Ge that was mined during the 1970s. Re-analysis of some beudantite specimens has shown them to be segnitite (Gebhard, 1999).
