The deposit, with very fine-graind gold, was discovered as a result of a geochemical exploration program in October 1984, during exploration for carbonate-hosted gold deposits area. It was discovered on the farm Navachab, 6 km south of the main Okahandja-Swakopmund tar road, and ca. 10 km SW of Karibib. Construction work began in 1988.

The 35 metre-thick ore body is hosted in a thick marble unit. The ore body dips at 70' to the west and plunges at 14' to the north and it is mined by open-cast method to a depth of over 200 metres. The ore body is estimated to contain 10.4 million tones of ore with average grade of 2.3 grams of gold per ton and a further 6.5 million tones of marginal ore with an average grade of 0.66 grams per ton. It was originally anticipated that the life of mine would be in the region of 13 years.

85% of the gold is unalloyed, 15% is alloyed with bismuth. The average gold grain size is 5 micron.
