Dugald River: a zinc operation in Australia

Dugald River is an underground mine producing zinc in near Cloncurry, north-west Queensland, Australia, operated by MMG. The sources report 183,463 tonnes of zinc in zinc concentrate for CY2025; the basis is whole mine, as reported by MMG. In zinc content, whole-operation output for CY2025 is 183,463 tonnes: about 1.4% of world zinc output in 2025 and about 17% of Australia's; it is one of 22 operations on this site whose output can be stated in zinc content.

How much does it produce?

Reported output of Dugald River
Period	Output	Basis	Where in the source
CY2025	183,463 tonnes of zinc in zinc concentrate MMG also reports payable zinc in product sold of 145,093 tonnes; the payable figure is not used.	whole mine, as reported by MMG	PDF p.18, table "Dugald River - Production", row "Zinc in zinc concentrate (tonnes)", column 2025; narrative PDF p.19 · MMG Limited
CY2024	163,588 tonnes of zinc in zinc concentrate	whole mine, as reported by MMG	PDF p.18, same row, column 2024 · MMG Limited

Between CY2024 and CY2025 the reported figure rose by 12.1%, in the same unit and on the same basis.

How the zinc-content figure is worked out. MMG prints 183,463 tonnes of zinc in zinc concentrate produced at Dugald River in 2025. MMG reports the Australian operations under assets in which it holds a 100% interest, so the figure covers the whole mine. World mine production of zinc in 2025 was 13,000,000 tonnes (USGS Mineral Commodity Summaries 2026); Australia produced 1,100,000 tonnes.

Status: operating, as of 31 December 2025.

MMG reports payable zinc in product sold separately (145,093 tonnes in 2025). Only zinc in zinc concentrate is used.

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 zinc 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 zinc mine. Shares of a country's output mix periods and bases, so treat them as indicative.
