Skorpion Zinc (NamZinc) is located 25km north of the town of Rosh Pinah, in the //Kharas Region of southern Namibia. Comprises Comprising an open-pit mine and refinery, Skorpion is the largest integrated zinc operation in Africa and is to VZI's vision for …
There are two operational mines: Skorpion Zinc (operated by Vedanta Resources) and Rosh Pinah (owned by various shareholders, with Exxaro Base Metals owning the largest interest at 46 percent). Lodestone, a mining company with U.S. shareholding, is extracting iron ore deposits in eastern Namibia.
The manganese at the Round Mountain Mine was discovered in rich pockets of residual clay (Ladd and Stead, 1944). Similar to the Flat Top Mountain District, the Round Mountain District was also assessed by the U.S. Bureau of Mines to determine how much recoverable ore remained in 1942.
The proposed line, passing by the Skorpion Zinc Mine, will start at Kudu Power Plant at Oranjemund, some 290 km from the Kokerboom Substation just north of Keetmanshoop. The following alternatives were identified and evaluated to supply the Skorpion Mining Project: Alternative A 220 kV power supply to the Skorpion Zinc Project from Oranjemund
Background The Skorpian Zinc mine is located in south-western Namibia. At the time of the environmental assessment, access to the proposed project site had been prohibited for many years due to its location within the diamond mining area of Sperrgebiet, and the site was therefore pristine.
The mine will source the zinc sulphide concentrate from Black Mountain and Gamsberg in the Northern Cape, South Africa. New sulphide deposits discovered in the …

The Gamsberg mine, at Aggeneys in the Northern Cape, will cost $630 million and produce 250 000 tonnes a year of zinc in concentrate. Processing in Namibia According to reports, Vedanta will truck 150 000 tonnes of zinc-and manganese-rich concentrate to its Skorpion zinc refinery in Namibia to process into metal.
The operation is expected to produce up to 500ktpa of zinc concentrate with an average manganese content of 2.5%. This level of manganese would attract a high penalty if marketed to smelters. Some may not accept the concentrate at all. Vedanta is looking to avoid this problem by treating the concentrate in-house at its nearby Skorpion refinery.

For more information visit Groote Eylandt mine. Remaining JORC resource: 138 Mt @ 43.6% Mn (ROM) and 9 Mt @ 19.5% Mn (Sands) The Groote Eylandt manganese mine has been in operation since 1965 and has produced more than 130 million tonnes of manganese ore and concentrate to June 2022.
Gamsberg currently produces 400,000 tonnes of ore per month. While the operational design is for 300 thousand tonnes of ore per month. During Phase 1, at full production capacity, Gamsberg will produce 4 million tonnes of ore from its open-pit mine and 250 thousand tonnes per annum of zinc-in-concentrate.
Although in 2000 the project had demonstrated a positive return on investment the decision to proceed to implementation was not granted due to the concerns around the imminent royalties bill legislation, the fact that the zinc price was at a 30. year low and the recent approval of the Skorpion mine in Namibia.. A zinc review in 2007 concluded that, …
