Manganese has long been considered a supporting metal in the global mining industry, primarily tied to steel production. More than 90 percent of global manganese consumption is used in the steel sector, where the metal acts as a critical alloying element that enhances strength, durability, and resistance to wear. On average, each tonne of steel requires 6 to 9 kilograms of manganese, making the metal indispensable for infrastructure, construction, transportation, and heavy industry.
In recent years, however, manganese has taken on new strategic importance as the global battery industry evolves. Lithium-ion battery chemistries such as nickel–manganese–cobalt (NMC) rely on manganese to stabilize cathode structures while reducing reliance on expensive cobalt. Emerging technologies—including lithium manganese iron phosphate (LMFP) and other high-manganese cathodes—are expected to significantly increase manganese demand in electric vehicles and energy storage systems.
This shift has drawn the attention of governments, manufacturers, and investors seeking to secure reliable supplies of battery materials. Global manganese ore production currently exceeds 20 million tonnes annually, with the majority coming from South Africa, Australia, and Gabon. Yet processing capacity for battery-grade manganese remains concentrated in a small number of countries, highlighting the need for diversified supply chains.
Across Africa and Europe, junior mining companies are now intensifying exploration efforts to identify new manganese deposits that could serve both the traditional steel industry and the emerging battery materials market. Around twenty exploration discoveries and promising districts illustrate how this sector is expanding beyond its historical production hubs.
Africa: The World’s Core Manganese Province
Africa remains the dominant geological region for manganese resources. One of the most significant deposits is the Kalahari Manganese Field in South Africa, widely recognized as the largest manganese resource base on the planet. The basin is estimated to contain more than 70 percent of global manganese resources and hosts numerous large-scale mines producing high-grade ore primarily used in steelmaking.
Despite decades of mining, exploration activity in the Kalahari Basin continues to uncover new mineralized zones. Junior companies have secured exploration licenses targeting extensions of known ore bodies concealed beneath layers of sedimentary cover. Recent drilling programs have intersected stratiform manganese layers grading above 30 percent Mn across several metres, indicating that the basin still holds substantial untapped potential.
Modern geophysical imaging techniques have played a key role in these discoveries. Advanced subsurface mapping technologies now allow geologists to detect mineralized horizons beneath thick overburden that previously masked important geological structures.
Further north, Gabon’s Moanda manganese district remains one of the world’s highest-grade manganese regions. Exploration programs across the wider Franceville Basin are identifying additional manganese-bearing formations within sedimentary rocks deposited in ancient marine environments.
Preliminary exploration results have reported manganese concentrations exceeding 35 percent Mn, suggesting that deposits comparable to Moanda’s existing operations may still exist within the basin. Several junior companies are now conducting geochemical surveys and early drilling campaigns to test these targets.
In Namibia, exploration has also revealed manganese mineralization within sedimentary formations linked to ancient oceanic environments. Geological studies suggest that manganese oxides accumulated in shallow marine basins during periods of intense biological activity millions of years ago.
Drilling across several Namibian prospects has intersected manganese-rich layers in sedimentary rocks. While still at an early exploration stage, these findings indicate the potential for Namibia to emerge as a new manganese producer in southern Africa if continuity and scale are confirmed.
West Africa’s Emerging Exploration Potential
West Africa is also attracting renewed interest from manganese explorers. In Ghana, geological surveys have identified manganese-bearing formations in the country’s western regions. Ghana previously produced manganese during the twentieth century, and modern exploration programs are now reassessing these historic districts.
Sampling campaigns have reported manganese grades ranging between 20 and 40 percent Mn, suggesting that new mining projects could eventually complement the country’s well-known gold industry.
Exploration in Côte d’Ivoire has also identified manganese occurrences within sedimentary basins associated with ancient marine deposits. Although these projects remain in early stages, geochemical data indicates the presence of manganese-rich layers that may justify further drilling campaigns.
Europe: Smaller Deposits with Strategic Value
Compared with Africa, manganese exploration across Europe is more limited, yet it is gradually expanding as governments seek to strengthen regional supply chains for critical raw materials.
In Ukraine, one of the world’s historic manganese producers, exploration programs continue to evaluate the vast Nikopol manganese basin. This large sedimentary formation already supports major mining operations, but new studies are identifying additional mineralized zones within deeper sedimentary layers that could extend the life of the basin’s production.
Further west, Romania hosts manganese deposits associated with metamorphic formations in the Carpathian Mountains. Junior exploration companies are revisiting historic mining districts where manganese extraction took place during the twentieth century. Modern geological surveys suggest that additional resources may exist at greater depths than earlier mining operations reached.
In Spain, exploration programs are examining manganese oxide mineralization within sedimentary basins in the northern part of the country. Although these deposits are generally smaller than those found in Africa, their proximity to European industrial markets could make them strategically important.
The Battery Revolution Reshaping Manganese Demand
The rapid expansion of the global battery sector is transforming how manganese resources are evaluated. Battery manufacturers increasingly require high-purity manganese sulphate, a processed chemical used in lithium-ion battery cathodes.
As a result, some exploration companies are now focusing on deposits that could be suitable for battery-grade manganese processing, rather than solely targeting ore for traditional steel applications.
Europe’s growing network of battery gigafactories is expected to require large quantities of manganese chemicals in the coming decade. As battery chemistries shift toward higher manganese content, the metal is emerging as a key component in efforts to reduce reliance on cobalt while maintaining performance and safety in electric vehicle batteries. This trend could ultimately lead to the development of integrated supply chains that connect manganese mining, refining, and battery manufacturing across Europe.
Opportunities and Challenges for Junior Explorers
For junior mining companies, manganese exploration offers several advantages. Deposits frequently occur in large sedimentary basins that can support cost-effective open-pit mining operations, and manganese processing is generally less complex than that required for many other battery metals.
The manganese market remains closely tied to global steel production cycles, which still account for the vast majority of demand. Fluctuations in steel output can therefore influence manganese prices and investment decisions. Despite these challenges, exploration momentum continues to grow as industries seek diversified supply sources for both steelmaking and battery technologies.
A New Chapter for Manganese Supply
Across sedimentary basins and ancient geological formations in Africa and Europe, exploration teams are gradually redefining the global distribution of manganese resources. The discoveries emerging today represent the early phase of a potential transformation in the manganese supply chain.
If even a portion of these exploration projects advances toward development, they could significantly expand global manganese production while reducing supply concentration in a handful of regions.
From the vast Kalahari Basin to emerging prospects in West Africa and Eastern Europe, drilling programs are uncovering the geological structures that host manganese mineralization. The junior explorers working in these regions are not merely discovering new deposits—they are helping shape the future geography of one of the world’s most essential industrial metals, supporting both steel infrastructure and the rapidly growing battery economy.
