Gamsberg is located about 30km from Black Mountain Mining (BMM) in the Northern Cape, South Africa. BMM is located at Aggeneys, a mining town in the province.

Vedanta holds 69.6%. Exxaro Resources, a leading South African BEE company owns 24.4% and ESOP holds 6%.

Gamsberg will exploit one of the largest known, undeveloped zinc orebodies in the world and comprises an open pit mine and a dedicated processing plant.


Gamsberg currently produces 400,000 tonnes of ore per month. While the operational design is for 333,333 tonnes of ore per month, we are currently exceeding production to make up for the shortfall experienced early in 2019. During Phase 1, at full production capacity Gamsberg will produce 4 000,000 tonnes of ore from its open pit mine and 250,000 tonnes per annum of zinc-in-concentrate. The project’s current reserve and resource is 214 million tonnes, with a grade of between 6 and 6.5%, and has a total life-of-mine (LOM) estimated at 30 years.


Studies into Gamsberg Phase 2 and 3 are underway which will see ore mined increase to 8 million tonnes per annum and production of zinc-in-concentrate to 450,000 tonnes, and, in a modular fashion, ultimately to 600,000 tonnes per annum. It will reflect an additional investment of US$350 to US$400 million.


Discovered more than 40 years ago and held undeveloped in the asset portfolios of various mining companies, it was acquired from Anglo American by the Vedanta group in 2011, as part of the Black Mountain Mining complex. Vedanta gave the project the go-ahead in 2014, and the first blast occurred in mid-2015 just eight months later. President Cyril Ramaphosa officially innaugurated Gamsberg on 28 February 2019.


Gamsberg employs more than 959 permanent direct employees. More than half of the employees are recruited from the Northern Cape, with over 25% from local communities. Gamsberg employed 3,000 people during the construction of the operation.


Community development initiatives are prioritised according to local needs and include:

  • Social investment (health, education and livelihoods)
  • Bio-investment (water harvesting, agriculture and social forestry)
  • Environmental conservation

These corporate social responsibility activities are included in the project’s business plans and appropriate implementation is carefully considered in collaboration with associates, government bodies and NGOs. Progress and performance are measured by third-party reviews and reported regularly to all stakeholders.


A critical feature of Gamsberg’s development is its approach to biodiversity. The Project is being developed in the ecologically sensitive Succulent Karoo Biome, a designated biodiversity "hotspot" and one of just 35 “biodiversity hotspots” in the world. This has required extensive engagement with key stakeholders – government, NGOs and landowners – which has resulted in a unique biodiversity offset agreement.

The project team is working in close partnership with the International Union for the Conservation of Nature (IUCN), the world's oldest and largest environmental organisation and in compliance with the Vedanta Sustainable Development Framework to ensure effective implementation of the agreement.


Vedanta is simultaneously pursuing a feasibility study into the development and construction of a smelter-refinery complex, which speaks to both Vedanta and Government’s commitment to local metal beneficiation.
