A company's copper is the sum of its operations, each at 100%: it is not its attributable output. An operation whose regulated unit is not linked yet does not appear under its company.

Those that own

Companies with a stake in others, as the document cited on each page states. Their largest stakes are shown.

Other companies

Companies with known owners that do not hold an operation with published output, and lithium producers.
