A complex and unusual Tsumeb specimen from the important collection of Cors De Bruin who was employed at Tsumeb starting in 1947. His label gives us the rare detail of locality (30 Level) and has his observation "real mixed-up thing!". The matrix is a heavy mass of Copper/Cuprite that is host to several vugs and zones packed with small crystals and botryoidal masses. The Wulfenites here are mostly the bipyramidal habit. This small specimen is loaded with Copper, Zinc and Lead minerals, the kind of mixing that really only is seen at Tsumeb and one of the reasons it is so revered by collectors.
