Manganese Reserves by Country

Australia's reported manganese reserves are nearly six times what they were in 2018. The figures come from the USGS Mineral Commodity Summaries 2019-2026 and cover estimated quantities that can be economically extracted under applicable conditions. Reserves refer to quantities that can be economically extracted under applicable conditions, rather than material mined in a particular year. The table covers 10 countries, with 7 reported 2025 values, and listed reserves totaled 1,798,000 thousand metric tons in 2025. The source gives a rounded world total of 1,800,000 thousand metric tons.

Australia (580,000 thousand metric tons) and South Africa (550,000) sit just 30,000 apart at the top. Brazil (300,000) and China (260,000) follow, putting 94.0% of the listed 2025 reserves in the top four countries. Gabon (61,000), India (34,000) and Ghana (13,000) make up the remainder.

Australia overtook South Africa in 2025, with reserves of 580,000 thousand metric tons versus 550,000, after trailing 500,000 to 560,000 in 2024.

Australia overtakes South Africa

South Africa led in 2024 with 560,000 thousand metric tons against Australia's 500,000. In 2025 Australia added 80,000 (+16.0%) while South Africa slipped 10,000 (-1.8%), flipping the order to 580,000 versus 550,000. Australia's path here ran from 99,000 in 2018 through 230,000, 270,000 and 500,000 — a climb of nearly sixfold, pausing only in 2022 and 2024.

China's 2022 jump

China reported 54,000 thousand metric tons from 2018 through 2021, then 280,000 for 2022 — more than a fivefold rise in a single step. It has eased to 260,000 in 2025 (-7.1%), while Brazil moved the other way, from 270,000 to 300,000 (+11.1%).

Three countries lack 2024 and 2025 values

Ukraine remained at 140,000 through 2023, while Kazakhstan and Mexico stayed at 5,000 through the same year. None of the three has a reported value for 2024 or 2025. Ghana, meanwhile, has reported 13,000 in every year of the series, while Gabon (61,000) and India (34,000) have remained unchanged since 2019.

Methodology

Figures come from the USGS Mineral Commodity Summaries 2019-2026, with 2025 values estimated. Units are thousand metric tons, exactly as reported. Empty means the source reported no value; 0 means the source reports zero. The source’s world total, where published, may be rounded, approximate, a lower bound, or a textual estimate, so shares are computed against the sum of the listed countries. Reserves and production are different measures and should not be combined without equalizing units.
