Different kinds of mineralisation occur on Farm Tubussis 22 (note that the tiny village of Tubussis, where many of the small scale Erongo miners live but no minerals are produced, is on the same farm):
- Miarolitic voids in the Erongo granite (e.g., 'Metazeunerite pocket').
- Calcsilicate rocks with demantoid, axinite and others.
Note: The farm and the village both officially fall under the Karibib District (not the Omaruru District, althought they fall on the southern most borders of the Omaruru District lines).
