Manganese Project Pipeline
The following projects represent the most significant Manganese operations and development-stage assets worldwide:
GEMCO (Groote Eylandt)
South32
One of the worlds largest and lowest-cost manganese mines, located on Groote Eylandt in the Gulf of Carpentaria
COMILOG (Moanda)
Eramet
Worlds largest manganese mine, located in southeastern Gabon; major expansion underway
Kalahari Manganese Field
Various (ARM, South32, Tshipi)
Hosts ~70% of known global manganese reserves; multiple operating mines including Mamatwan, Wessels, and Tshipi Borwa
Gruyere HPMSM Plant
Euro Manganese
Proposed high-purity manganese sulfate plant processing historical mine tailings for European EV battery supply chain
Government Support and Strategic Initiatives
Recognizing the strategic importance of Manganese, governments in major consuming nations have launched programs to support project development. These include direct financing, loan guarantees, streamlined permitting, and bilateral resource partnerships. As a USGS-listed critical mineral, Manganese projects are eligible for various U.S. government support mechanisms including the Defense Production Act Title III program. EU Critical Raw Materials Act provisions enable fast-track permitting and financing support for Manganese projects within the EU and partner nations.
Key Industry Developments
Recent developments affecting the Manganese project landscape:
South Africas Transnet rail and port bottlenecks constrained manganese exports, supporting prices despite adequate mine supply
Battery-grade high-purity manganese sulfate (HPMSM) demand surged as EV battery production scaled; shortage of HPMSM processing capacity emerged
Manganese ore prices fell as Chinese steel production growth slowed; battery-grade manganese remained in higher demand
Multiple HPMSM projects announced globally as EV battery manufacturers sought non-Chinese high-purity manganese supply
