Gamsberg: a zinc operation in South Africa
Gamsberg is a mine producing zinc in Northern Cape, South Africa. The sources report 185 thousand tonnes ('000 tonnes) of mined metal content for FY2026 (1 April 2025 to 31 March 2026); the basis is as reported by Vedanta Limited for the mine; the release does not state whether this is 100% of the mine. The sources do not give a whole-operation figure in zinc content that can be compared with world output, so no share is computed.

Method and limits
- Reported, not estimated. Output is the figure the operator or owner published, in the unit it used. This site does not estimate output where none is published.
- Shares. A share divides output in zinc content by the USGS world or country total for 2025. Where the operator's year is a fiscal year or the unit is a concentrate or a carbonate equivalent, the share is approximate or not given.
- Whole operation or owner's share. The basis column says which. A joint venture's output is never counted twice.
- Partial list. Only operations with a published figure are listed, so the rank is among those on this site, not among every zinc mine. Shares of a country's output mix periods and bases, so treat them as indicative.
