El Porvenir: a zinc operation in Peru
El Porvenir is an underground mine producing zinc in Peru (part of the Cerro Pasco Complex), Peru, operated by Nexa Resources. The sources report 53.1 thousand tonnes of zinc contained in concentrates for CY2025; the basis is 100% of the mine, as reported by Nexa Resources. In zinc content, whole-operation output for CY2025 is 53,100 tonnes: about 0.4% of world zinc output in 2025 and about 3.5% of Peru's; it is one of 22 operations on this site whose output can be stated in zinc content.

How much does it produce?
| Period | Output | Basis | Where in the source |
|---|---|---|---|
| CY2025 | 53.1 thousand tonnes of zinc contained in concentrates | 100% of the mine, as reported by Nexa Resources | printed p.34, Item 4 "Producing mines", El Porvenir paragraph: "approximately 53.1 thousand tonnes of zinc contained in concentrates"; Earnings release (Form 6-K) printed p.23, El Porvenir table "(100% basis)", row "Production - metal contained - Zinc", column 2025 · Nexa Resources S.A. |
| CY2024 | 50.6 thousand tonnes of zinc contained in concentrates | 100% of the mine, as reported by Nexa Resources | printed p.23, El Porvenir table "(100% basis)", row "Production - metal contained - Zinc", column 2024 · Nexa Resources S.A. |
Between CY2024 and CY2025 the reported figure rose by 4.9%, in the same unit and on the same basis.
How the zinc-content figure is worked out. Nexa Resources prints 53.1 thousand tonnes of zinc contained in concentrates produced by the El Porvenir mine in 2025, and its earnings release labels the mine table "100% basis". The figure covers the whole mine. 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 31 December 2025.
- The 20-F lists El Porvenir as part of the Cerro Pasco Complex.

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.
