Las Bambas: a copper operation in Peru
Las Bambas is a mine producing copper in Apurímac region, Peru, operated by MMG. The sources report 410,834 t copper in copper concentrate for CY2025; the basis is the whole operation. In copper content, whole-operation output for CY2025 is 410,834 tonnes: about 1.8% of world copper output in 2025 and about 15% of Peru's; it is one of 11 operations on this site whose output can be stated in copper content.

How the copper-content figure is worked out. MMG reports 410,834 tonnes of copper in copper concentrate (contained copper) for the whole operation. World mine production of copper in 2025 was 23,000,000 tonnes (USGS Mineral Commodity Summaries 2026); Peru produced 2,700,000 tonnes.
Status: operating, as of 3 March 2026.

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 copper 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 copper mine. Shares of a country's output mix periods and bases, so treat them as indicative.
