Description
Stalactitic goethite on a dense, gossanous matrix, thickly encrusted with apple-green to bottle-green conichalcite (XRD indicated; Paul Carr, University of Wollongong, 2016). A little malachite is associated locally.
The specimen was number 985 in the collection of Wilhelm Klein, production manager at Tsumeb between 1916 and 1939. Klein mistakenly labelled it as "Zinkspat" [smithsonite]; his handwritten catalogue attributes it to 8 Level West.
