El Teniente · Copper: total contained copper at the mine production 2025

As of 2026-10-25 · Observation periods are shown separately.

El Teniente is a copper operation in Chile operated by Codelco. In 2025 (2025-01-01 – 2025-12-31) it produced 310,000 t of total contained copper at the mine on a 100% project basis, as disclosed by Codelco. The tables below keep each disclosure's own period and source; a later actual does not establish whether the original expectation was met.

Recompute in tonnes. A midpoint is an arithmetic reference, not an issuer point forecast. Percentage changes use the corresponding reference value; a zero denominator has no percentage.

Change=310000 - 356000

Percentage = difference / reference × 100=(310000 - 356000) / 356000 * 100

Figures are provisional. Codelco corrected its 2025 corporate own-production total on 28 July 2026 (Chuquicamata and Ministro Hales only); El Teniente is not listed as changed, which is an inference by omission. Divisional 2024–2025 figures remain under external review. Single-quarter values other than Q1 are differences of printed cumulatives and are marked derived.

What did El Teniente produce in 2025, and is the figure final?

Codelco reports 310,000 t of own copper production for 2025, down from 356,000 t in 2024; the printed first-quarter, first-half and nine-month cumulatives are 80,000, 172,000 and 234,000 t. Codelco published no division-level numeric guidance for El Teniente in 2025 or 2026, so no guidance comparison is made.
