Very common. Widespread throughout the Tsumeb deposit, but generally as lamellar intergrowths with chalcocite, from which it is visually indistinguishable.
- 1st Oxidation Zone
- 2nd Oxidation Zone
- 3rd Oxidation Zone
Excellent crystals of "chalcocite" found in the third oxidation zone, between 44 and 47 levels, are in fact a 50:50 mixture of chalcocite and djurleite (Gebhard, 1999).
