Glencore to raise global copper production by 2035

Global metals producer Glencore expects to increase its copper output to 1.6mn t by 2035, on the back of mine expansions, but faces short-term copper challenges.

It plans to produce 1.1mn t of copper in 2029, up from 850,000-875,000t in 2025, Glencore told investors in a capital markets day presentation on 3 December. It will then further increase production to around 1.6mn t by 2035, the company added.

Glencore's copper growth will come largely from the planned mine developments and restart projects (see table) over the next few years, including the 2028 reopening of its Alumbrera mine in Argentina.

Development work at the company's Collahuasi mine — a joint venture with UK-South African producer Anglo American and Mitsui-owned producer Japan Collahuasi — in Chile will also support its growth plan.

The project will increase Glencore's long-term output but has dampened its short-term production outlook. The company cut its 2026 copper production guidance to 810,000–870,000t on 3 December, from 930,000t in February, because of mine plan changes at the site.

Total production at Collahuasi fell by 31pc on the year in July-September, from 431,200t to 297,000t, because of lower ore grades, data from Chilean copper commission Chochilco show.

The mine will operate at a reduced rate in 2026 because of development work, Anglo American told investors on 29 October.

Glencore also cut the upper bound of its 2025 copper production guidance from 890,000t to 875,000t in late October because of operational and ore grade issues. It expects to produce at the lower end of its 850,000–875,000t range over the year.

The company mined 583,500t of copper in January-September, down by 17pc on the year.
