A world-famous Cu-Pb-Zn-Ag-Ge-Cd mine, renowned for a wealth of rare and unusual minerals. On January 21, 1893, Matthew Rogers discovered the "green hill," and the site started operating in 1907 and closed in 1996 for economic reasons.
However, even before the "official" discovery, the deposit had been known for ages by local Bushmen and exploited by them artisanally to recover copper.
Mineralisation is hosted in Neoproterozoic Otavi dolomite. The orebody is an ore pipe. It is about 120 by 15 meters in cross-section, steeply dipping and extending from the surface to at least 1,000 meters in depth. Controls for ore emplacement include interrupted circular fracturing, core breccia, and an internal mass of pseudo-aplite (Tsumeb Pipe). Local rocks include mainly Late Proterozoic sedimentary terrane.
Workings include extensive underground openings to a depth of 1,000 meters.
The De Wet shaft is on Main Street.
The Mindat icon shows the surface plant.
Please look for the other icons to see the location of the former "green hill" and exploitation of the early days and also where the De Wet and Friedrich-Wilhelm shafts are situated.

| β Acanthite Formula: Ag2S |

| β Formula: Zn2(AsO4)(OH) Description: Analysis shows less than 0.1% Cobalt, consequently cannot be regarded as 'cobaltoan' |
| β Formula: (Zn,Cu)2AsO4OH Description: "Cuprian adamite" is primarily Zincolivenite or close to end-member Adamite. References: |
| β Agardite-(Ce) Formula: CeCu6(AsO4)3(OH)6 · 3H2O |
| βͺ Alamosite Formula: PbSiO3 Habit: divergent sprays Colour: clear / white Description: βUntil the nineteen seventies the presence of lead silicates was unknown at Tsumeb. The first lead silicate specimen, alamosite, was discovered during a photographic session at the collection of W.R. Kahn. A piece of aragonite was to be featured, but the specimen that was photographed was slightly too heavy for aragonite. It was composed of radiating 8 cm spray of bundles of elongated, terminated white crystals up to 4 cm. The luster was also different to the known luster of the carbonate. Further examination gave the surprising result that this aragonite was in fact alamosite. This particular specimen is the best alamosite yet found anywhere. Another great specimen belongs to the collection of the Houston Museum. Tsumeb is the only locality from which crystals of alamosite have been reported, and a total of about 20 specimens have been found. Alamosite is often associated with small green-black spheres of melanotekite.β1
