See link to article in Mining Weekly at the bottom - Vedanta has announced that a feasibility study into the development and construction of a zinc smelter-refinery complex at their Gamsberg operation the Northern Cape is under way. The Gamsberg refinery could see a further investment by Vedanta of between US$700-million and US$800-million.
Gamsberg is not far from the Prieska Project and ore can easily be transported to Gamsberg in the future. The zinc and copper concentrate from Prieska were very sought after by smelters in the past due to low deleterious elements - i.e. very "clean" concentrates making them attractive for smelters or as a blending product for bulk concentrate traders.
The Northern Cape region of SA is poised to become the world's largest zinc supply region and having large player like Vedanta with its Gamsberg operation in the same region as the  Prieska Project, could provide an array of opportunities for the Prieska Project and ORN.
