Development of Gamsberg project was announced in November 2014, which included development of 4 million tonne per annum (MTPA) open pit zinc mine, concentrator plant and associated infrastructure. Vedanta expects ore production to start from 2018 with 9-12 month ramp-up to full production.
"We will invest a total of USD 1 billion in the Gamesberg project over the next three years, of which around USD 150 million has already been invested," Vedanta Resources Chairman Anil Agarwal told PTI.
On investments in Africa, Agarwal said: "Vedanta Resources has invested around Rs 25,000 crore in Africa in the last 13 years. We have a strong presence in Namibia, Zambia and South Africa."
The London-listed firm mines copper in Zambia at Konkola Copper Mines (KCM) and produces zinc and lead concentrate at Black Mountain Mining (BMM) in South Africa. It also produces special high grade zinc metal at Skorpion Zinc in Namibia.

On the Gamesberg project, it has invested USD 150 million and will invest USD 200 million each this year and in 2017. After the production starts at the mines, the firm will invest around USD 450 million on ramp-ups during 2018 and 2019.
The MoUs are for the development and supply of equipment and transfer of technology, with an aim to improve safety and productivity at the mechanised underground mines of Vedanta's subsidiary, Hindustan Zinc Ltd (HZL).
For a natural resources company like Vedanta, South Africa offers a unique opportunity with its wealth of diverse natural resources, Agarwal said.
"We are committed to expanding operations here and will continue to invest at Gamsberg. We already have a significant presence in South Africa and are well placed to help realise the vision of our Prime Minister of shared growth between India and South Africa in the future," he added.
