Kumba: the mines it operates or owns, and what they report

Kumba is a listed company headquartered in South Africa (Johannesburg Stock Exchange: KIO). This site lists 2 operations tied to it, for iron ore: it operates 2 and holds an interest in 0 more. On the operations here where a whole-operation figure can be stated (in metal content, or as the commodity page says for ore and smelted metal), its interests add up to about 27,207,300 tonnes of iron ore as ore, not iron content (1% of world output). That leaves out operations without such a figure, so it is not the company's total.

How much is that on its interests?

iron ore: 27,207,300 tonnes of iron ore as ore, not iron content across 2 operations, about 1% of world output. Periods differ by operation (CY2025).

Computed as each operation's whole-operation output in metal content, or as ore or smelted metal where the commodity is measured that way, multiplied by the interest shown. Operations whose output is stated in another form, or only as the owner's share, are left out of this sum, so it understates what the company controls.
