Antamina (zinc): a zinc operation in Peru
Antamina (zinc) is a copper zinc mine producing zinc in northern Peru. The sources report 454,800 tonnes of zinc production for CY2025; the basis is 100% of Antamina, as reported by Teck (22.5% holder). In zinc content, whole-operation output for CY2025 is 454,800 tonnes: about 3.5% of world zinc output in 2025 and about 30% of Peru's; it is one of 22 operations on this site whose output can be stated in zinc content.
Who owns and operates it?
| Owner | Interest | As of |
|---|---|---|
| Teck | 22.5% | 18 February 2026 |
| BHP | 33.75% | 18 February 2026 |
| Glencore | 33.75% | 18 February 2026 |

How much does it produce?
| Period | Output | Basis | Where in the source |
|---|---|---|---|
| CY2025 | 454,800 tonnes of zinc production | 100% of Antamina, as reported by Teck (22.5% holder) | printed p.8, Antamina section: "On a 100% basis ... Zinc production in 2025 increased significantly to 454,800 tonnes" · Teck Resources Limited |
| CY2024 | 267,900 tonnes of zinc production | 100% of Antamina, as reported by Teck (22.5% holder) | printed p.8, Antamina section · Teck Resources Limited |
Between CY2024 and CY2025 the reported figure rose by 69.8%, in the same unit and on the same basis.
How the zinc-content figure is worked out. Teck prints 454,800 tonnes of zinc production for Antamina on a 100% basis for 2025. Teck lists its 22.5% interest as 102 thousand tonnes in a table headed 'Contained in concentrate' (22.5% of 454,800 is 102,330 tonnes, consistent with the 102.3 thousand tonnes Teck prints for its share), so the whole-mine figure is read as zinc contained in concentrate. World mine production of zinc in 2025 was 13,000,000 tonnes (USGS Mineral Commodity Summaries 2026); Peru produced 1,500,000 tonnes.
Status: operating, as of 18 February 2026.
- Antamina is also listed under copper (the copper entry for Antamina). Do not add the owners' shares (Teck 22.5%, BHP 33.75%, Glencore 33.75%, Mitsubishi Corporation 10%) to the 100% figure.
- Teck reports 102.3 thousand tonnes as its 22.5% share and Glencore reports 152.6 thousand tonnes as its 33.75% share. Divided by the interests, these give 454.7 and 452.1 thousand tonnes.

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.
