Vedanta has inaugurated an expansion of its Gamsberg zinc mine in South Africa’s Northern Cape following an investment of nearly US$600 million. The project doubles the mine’s annual ore-processing capacity to 8 million tonnes and raises its stated annual zinc-in-concentrate capacity to approximately 500,000 tonnes. According to the official inauguration address, President Cyril Ramaphosa opened the Phase II concentrator on October 16, 2026.
Key Overview
- Investment: Nearly US$600 million for the Gamsberg Phase II expansion.
- Ore capacity: Doubles from about 4 million to 8 million tonnes annually.
- Zinc capacity: Approximately 500,000 tonnes of zinc-in-concentrate per year, not confirmed current output.
- Employment: The expanded operation is expected to sustain 800–1,000 jobs, following more than 1,500 construction jobs.
- Long-term plan: Vedanta wants to expand regional zinc output and develop local smelting capacity, subject to suitable infrastructure and commercial conditions.
Gamsberg Phase II Expands South Africa’s Zinc Industry
Gamsberg, near Aggeneys in the Northern Cape, is a flagship operation of Vedanta Zinc International. The newly inaugurated concentrator increases the amount of ore the mine can process, strengthening its capacity to supply zinc concentrate to industrial markets.
The expansion includes a new processing facility and supporting infrastructure. Vedanta’s project progress report identifies a new concentrator, additional water facilities, electricity infrastructure and a tailings-storage facility among the developments associated with Phase II.
The 500,000-tonne figure refers to annual production capacity for zinc contained in concentrate, not 500,000 tonnes of refined metal already produced. Actual output will depend on operational ramp-up, ore grades and plant performance.

How the $600 Million Project Fits Vedanta’s Investment Pledge
The expansion forms part of a wider R21 billion investment commitment made by Vedanta at the 2018 South Africa Investment Conference. During the October 16 opening ceremony, Ramaphosa highlighted the project’s progression from a pledged investment to an operational facility.
The mining group has a longer-term ambition to produce 3 million tonnes of zinc annually across its India and South Africa businesses. Under the stated expansion targets, Hindustan Zinc would contribute 2 million tonnes and Vedanta Zinc International 1 million tonnes. These remain targets rather than verified current production levels, and the figures cover different zinc product forms.
Zinc is widely used to galvanise steel, protecting it from corrosion in construction, transport and manufacturing. Expanded supply could strengthen the region’s role in global industrial supply chains.
Jobs, Communities and Local Economic Benefits
The expanded mine is expected to support 800 to 1,000 operational jobs, many involving workers from the Northern Cape. The president’s employment figures indicate that more than 1,500 people worked during construction.
Vedanta has also reported spending nearly US$20 million on community programmes since 2011, covering education, health, livelihoods and infrastructure. Its reported community investment activities include an oncology centre established in the Namakwa region during 2026. The spending and beneficiary figures are company-reported rather than independently audited in the cited coverage.
Proposed Zinc Smelter Could Add More Local Value
South Africa’s government wants mining investment to generate more domestic processing and manufacturing instead of relying mainly on exports of mineral concentrate. Ramaphosa welcomed Vedanta’s ambition to establish a zinc smelter in the Northern Cape, which could turn concentrate into refined zinc and create opportunities for suppliers and skilled workers.
However, the smelter is a proposed future investment, not part of the newly opened concentrator. In his remarks on local mineral processing, the president acknowledged that competitive electricity, reliable infrastructure and commercially viable operating conditions would be essential.
The Gamsberg expansion gives Vedanta a larger production base, but the project’s longer-term economic impact will depend on how quickly capacity translates into output, stable employment and further investment in South African processing facilities.
