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

Teck is a listed company. This site lists 3 operations tied to it, for zinc and copper: it operates 1 and holds an interest in 2 more. On the operations here where a whole-operation figure in metal content can be stated, its interests add up to about 85,900 tonnes of copper (0.4% of world output) and 102,300 tonnes of zinc (0.8% 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?

copper: 85,900 tonnes of content across 1 operation, about 0.4% of world output. Periods differ by operation (CY2025).
zinc: 102,300 tonnes of content across 1 operation, about 0.8% of world output. Periods differ by operation (CY2025).

Computed as each operation's whole-operation output in metal content 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.
