Description

A vug in massive sulphide ore, lined with crystals of tennantite and quartz. Ludlockite fibres and sheaves are sparsely distributred on some of the tennantite and quartz crystals and the cavity is bridged by a circa 20 mm blade of leiteite (Exhibit 2). At the back of the cavity (as photographed) is a group of slender, colourless stibioclaudetite blades (to 3 mm), striated and double-terminated (Exhibit 3).

This is the specimen from which the mineral stibioclaudetite was originally described (Origlieri et al. 2009). Bill Pinch acquired it from dealer Dave Bunk, but its earlier provenance and location in the mine are not recorded. It provided the registered type material conserved at the Smithsonian Institute (catalogue number 174550). Pinch’s label is shown in Exhibit 4.
