Köppen climate type:


Sediment-hosted, structurally controlled, mesothermal gold deposit on State owned land, mining area 10 km². Discovered in 1917, claims where first staked in 1922, a minor gold rush began. Initial production began on alluvial and eluvial workings, with some 11,600 Oz Au reported from 1923 to 1945. Located NNW of the Navachab gold mine, and east of the villages Ondundu and Ondundotjuapa.


"Ondundu gold mineralization is concentrated in the hinge zone of a large north-south trending, southerly plunging antiform within metasediments of the Kuiseb Formation and features multiple gold-bearing quartz vein sets. Widespread alteration including tourmalinisation, silicification, pyritisation, dolomitisation and albitisation increases in intensity toward the anticline. Mining of the veins along a 2.5 km corridor occurred on a relatively small-scale from five individual claim groups or mining areas from 1917 until 1963 producing an estimated 19,851 ounces of gold (Venter, Carter, 1983). The majority of the historical gold production came from proximal alluvial-eluvial deposits. Underground mining was limited to approximately sixty metres below surface by the water table."

Note: Namibia ministry of mines refers to area as the Ondundu mine and Ondundu gold fields (figure 1, http://www.mme.gov.na/gsn/pdf/gold.pdf).
