schaurteite

calcite; germanite (?); ludlockite (?); renierite (?); tennantite-(Zn) (?)

White to off-white fibrous crystals of schaurteite (to 4 mm) forming tight, compact aggregates of closely parallel individuals, locally intergrown with minor cream-white calcite, occupying a shallow vug and partings in germanium-rich massive sulphide ore (Exhibit 2).  Sparse and isolated occurrences of fibrous orange ludlockite (?) are present in the sulphide but not in direct association with the ludlockite.

The provenance can be traced back to Julius and Miriam Zweibel (early 1990s), who sold the specimen to Californian collector/dealer Will Frech. Frech sold it to Australian collector Paul Melville in the mid 1990s and some 20 years later, Melville traded it to Rob Sielecki who passed it on to Ian Bruce.

There is no record of location in the mine but the paragenesis is strongly indicative of the second oxidation zone.
