Goodchild, of the Scottish Geological Survey, found wulfenite there in 1875 but the locality only really became of interest to collectors in the 1950s following the reporting of a suite of rare supergene minerals including bayldonite, duftite, beudantite, carminite
, lindgrenite and stolzite (the first authenticated British occurrence).
Some of the finest examples were found associated with carminite
; another associated species is lepidocrocite (Gebhard, 1999).
The Bushveld Complex is not only a fascinating geological feature, but also the source of numerous interesting micromineral species including carminite, scorodite, crocoite, linarite, julgoldite, anatase and munirite.
Carminite, beudantite, scorodite and olivenite have been collected off the old dumps.
The first discovery of carminite
in Japan has been made nearly simultaneously at two localities: the Tsuzura mine, Miyazaki prefecture and the Kiura mine district, Ohita prefecture, both in Kyushu.
