Otjizonjati Mine


The Otjisongati mines form a component of the Onjati mountains which lie in the northeast spurs of the Khomas highland which pulls through the middle from Namibia as a spine of SSW after NNE. On an elevated plain, about 60 km air line northeast of Windhoek, that consists of gneiss and mica schist basically, there are more than 20 lodes from which some were subject of the mining industry in a sea level of 2020 m on a narrow area of 1,5 square miles.
The mines were locked around 1912.
