Overview

Archive Note

The Escondida operation lies in the Atacama Desert roughly 170 km southeast of Antofagasta and consists of major copper pits and associated mineral deposits.

BHP separately reports Escondida, Escondida Norte, Pampa Escondida and Pinta Verde, some not yet mined. The approximately 26 billion tonnes is a resource inventory across the defined district, not metal already extracted or proven recoverable ore reserves.

Verification basis and limitations

Verified

The record conclusion has sufficient verification support.

Basis: direct confirmation by an authority

BHP's 2024 Escondida district materials support approximately 26 billion tonnes at 0.53% copper, including neighboring deposits; this is neither one pit's ore reserve nor copper metal content. The worldwide superlative depends on the aggregation boundaries of the mining district.
