Moa joint venture: a cobalt operation in Cuba
Moa joint venture is a nickel laterite producing cobalt in Moa, Cuba. The sources report 2,728 tonnes finished cobalt (Moa JV, 100% basis) for CY2025; the basis is the whole operation. 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 |
|---|---|---|
| Sherritt International | 50% | 10 February 2026 |
| Joint venture partner (not named in the sources used) | — | 10 February 2026 |
How much does it produce?
| Period | Output | Basis | Where in the source |
|---|---|---|---|
| CY2025 | 2,728 tonnes finished cobalt (Moa JV, 100% basis) | Whole operation | Highlights paragraph 'Full year 2025 production reached 25,240 tonnes of nickel and 2,728 tonnes of cobalt (100% basis)'; table 'Metals - Moa JV (100% basis, tonnes)' · Sherritt International Corporation |
| CY2024 | 1,603 tonnes finished cobalt, Sherritt's 50% share | attributable | MD&A text, Metals, full-year production paragraph ('1,364 tonnes ... compared to 1,603 tonnes') · Sherritt International Corporation |
Status: operating in CY2025.
- The figure is finished (refined) cobalt from Moa mixed sulphides, refined in Alberta, and Sherritt's release says it bought no additional third-party feed in the second half. It is not cobalt mined at Moa, so no share of world mine output is computed. It comes from Sherritt's release, as a 50% holder.

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.
