Tara: a zinc operation in Ireland
Tara is a mine producing zinc in Ireland, operated by Boliden. The sources report 75,817 tonnes of zinc, "Production of metal in concentrate" for CY2025; the basis is whole mine, as reported by Boliden. In zinc content, whole-operation output for CY2025 is 75,817 tonnes: about 0.6% of world zinc output in 2025; it is one of 22 operations on this site whose output can be stated in zinc content.

Between CY2024 and CY2025 the reported figure rose by 1094.3%, in the same unit and on the same basis.
How the zinc-content figure is worked out. Boliden prints 75,817 tonnes of zinc as metal in concentrate for Tara for the full year 2025 in its unit table. This is contained zinc for the whole mine. World mine production of zinc in 2025 was 13,000,000 tonnes (USGS Mineral Commodity Summaries 2026).
Status: operating, as of 31 December 2025.
- Boliden reports 1,441 kilotonnes of milled ore at a head grade of 5.6% zinc for Tara in 2025, and 156 kilotonnes at 4.3% in 2024.
- Boliden's year-end report refers to the restart of Tara as a contributor to higher volumes in 2025.

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.
