Australia’s Groote Eylandt mine to support global manganese supply growth in 2026

Group 1 - Global manganese production is heavily concentrated in Africa, with South Africa, Gabon, and Ghana accounting for a substantial share of total output, reinforcing Africa's strategic role in the global manganese supply chain [1] - In 2025, global manganese production is estimated to increase by 10.8% to 57.3 million tonnes, primarily driven by supply growth from Ghana and Australia, with Ghana's production growth linked to the ramp-up of operations at the Nsuta mine [2] - The Groote Eylandt mine in Australia is expected to resume operations in May 2025, following a suspension due to Tropical Cyclone Megan, which will significantly enhance Australia's supply contribution in 2025 [2] Group 2 - In 2026, global manganese output is forecasted to rise by 3.3% to 59.1 million tonnes, largely supported by Groote Eylandt reaching full production capacity after its 2025 restart [3] - Production from other major suppliers, including South Africa, Gabon, and Ghana, is expected to remain broadly flat due to the absence of significant new capacity additions, which is notable given supply disruptions in other regions [4] - Global markets are increasingly reliant on output from South Africa, Gabon, and Ghana to meet sustained demand, particularly from the steel and electric vehicle battery sectors, with a projected compound annual growth rate of 0.6% in global manganese production from 2025 to 2035 [5]
