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

Global manganese accumulation remains heavy concentrated successful Africa, with South Africa, Gabon, and Ghana collectively accounting for a important stock of full output. This attraction reinforces Africa’s strategical relation successful the planetary manganese proviso concatenation and highlights the sector’s structural dependence connected a constricted fig of producing regions.

In 2025, planetary manganese accumulation is estimated to person accrued by 10.8% to 57.3 cardinal tonnes (mt), chiefly supported by proviso maturation from Ghana and Australia. Ghana’s accumulation maturation reflects the continued ramp-up of operations astatine the Nsuta mine, portion Australia’s betterment is linked to the phased resumption of mining astatine the Groote Eylandt excavation from May 2025. Operations astatine Groote Eylandt were suspended successful March 2024 pursuing disruptions caused by Tropical Cyclone Megan, and their restart is expected to materially fortify Australia’s proviso publication successful 2025.

Looking up to 2026, planetary manganese output is forecast to emergence by a further 3.3% to 59.1mt, mostly underpinned by Groote Eylandt reaching afloat accumulation capableness pursuing its 2025 restart. This ramp-up is expected to beryllium a cardinal operator of incremental planetary proviso maturation successful Australia during the year.

In contrast, accumulation from different large suppliers, including South Africa, Gabon, and Ghana, is expected to stay broadly flat, reflecting the lack of important caller capableness additions. However, this stableness is peculiarly important against the backdrop of proviso disruptions elsewhere. The suspension of mining astatine Kazakhstan’s Kazmarganets excavation since December 2023 owed to assets depletion, combined with ongoing geopolitical disruptions affecting accumulation successful Ukraine, has tightened proviso from non-African regions.

As a result, planetary markets are progressively reliant connected output from South Africa, Gabon and Ghana to conscionable sustained demand, particularly from the alloy and electrical conveyance artillery sectors. Over the forecast play (2025-2035), planetary manganese accumulation is expected to turn marginally with a compound yearly maturation complaint (CAGR) of conscionable 0.6% to 60.6mt by 2035.
