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

Glencore is a listed company headquartered in Switzerland (London and Johannesburg stock exchanges). This site lists 10 operations tied to it, for cobalt, zinc, bauxite, copper and nickel: it operates 7 and holds an interest in 3 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 5,202,000 tonnes of bauxite (1.2% of world output) and 26,100 tonnes of cobalt (8.4% of world output) and 260,900 tonnes of copper (1.1% of world output) and 716,300 tonnes of zinc (5.5% 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?

bauxite: 5,202,000 tonnes of bauxite across 1 operation, about 1.2% of world output. Periods differ by operation (CY2025).
cobalt: 26,100 tonnes of content across 2 operations, about 8.4% of world output. Periods differ by operation (CY2025).
copper: 260,900 tonnes of content across 2 operations, about 1.1% of world output. Periods differ by operation (CY2025).
zinc: 716,300 tonnes of content across 3 operations, about 5.5% 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.
