05Ways to take part
Not investment advice. This says how the public can reach a company — a job, its shares, its products — not whether anyone should. It takes no account of anyone’s circumstances, and a company holding a chokepoint is not a reason to own it. What this is not
- Work there
- It publishes its roles on its own careers page.Official careers page ↗
- Own part of it
- Not listed on its own: it is part of Anglo American, whose shares trade publicly as AAL LN. Owning those is owning the whole group, of which this is one part.AAL LN listing record ↗
- Buy from it

A loop is one design, build and measure turn. Severity is a dated judgement on a 0–12 scale, not a measurement, and the judgements are not added together — the figure shown is the worst single one.
