Murrin Murrin: a cobalt operation in Australia
Murrin Murrin is a nickel laterite producing cobalt in Western Australia, operated by Glencore. The sources report 2.2 kt cobalt metal (own sourced) for CY2025; the basis is as reported by operator. The sources do not give a whole-operation figure in cobalt content that can be compared with world output, so no share is computed.
Who owns and operates it?
| Owner | Interest | As of |
|---|---|---|
| Glencore | 100% | 31 December 2025 |
How much does it produce?
| Period | Output | Basis | Where in the source |
|---|---|---|---|
| CY2025 | 2.2 kt cobalt metal (own sourced) | as reported by operator | PDF p.12, table 'Production from own sources - Nickel assets', Murrin Murrin Cobalt metal row (also PDF p.5) · Glencore plc |
| CY2024 | 2.5 kt cobalt metal (own sourced) | as reported by operator | PDF p.5 and p.12 · Glencore plc |
Between CY2024 and CY2025 the reported figure fell by 12.0%, in the same unit and on the same basis.
Status: operating in CY2025.
- The figure is cobalt metal from the operation's own sources, not cobalt contained in ore or concentrate, so no share of world mine output is computed.

Method and limits
- Reported, not estimated. Output is the figure the operator or owner published, in the unit it used. This site does not estimate output where none is published.
- Shares. A share divides output in cobalt content by the USGS world or country total for 2025. Where the operator's year is a fiscal year or the unit is a concentrate or a carbonate equivalent, the share is approximate or not given.
- Whole operation or owner's share. The basis column says which. A joint venture's output is never counted twice.
- Partial list. Only operations with a published figure are listed, so the rank is among those on this site, not among every cobalt mine. Shares of a country's output mix periods and bases, so treat them as indicative.
