Rich bright yellow Tsumcorite covers an area up to 3cm by 3cm, with extension into a 1 x 1cm cavity. This specimen comes from the type location of the Tsumeb mine. The Tsumcorite is composed of well developed intergrown platy disc-like micro-crystals, with a later phase of olive-green micro-acicular Olivenite. The Olivenite forms aggregated and scattered crystals, some as a wheat-sheaf habit. Both have grown on a matrix of dense white Dolomite which is crosscut by thin veinlets of Olivenite and Cuprian Adamite, and reddish Iron oxides with remanent Sulphides. There is an area of crystalline light blue-green Cuprian Adamite on the underside of the specimen measuring 2 by 1.5cm. Several other small cavities also harbour Olivenite with later crystals of Cuprian Adamite. An excellent specimen of the rare species Tsumcorite, with two other Arsenate species.
