Why Tanzania Could Become Africa’s Next Battery Minerals Hub

The global energy transition is creating a new class of strategic resources. Lithium, graphite, nickel, cobalt and rare earth elements have become the backbone of the battery economy, powering everything from electric vehicles to grid-scale storage systems.

Tanzania is quietly positioning itself within that supply chain.

Through the State Mining Corporation (STAMICO), the government has opened a series of exploration licences targeting exactly these minerals. The projects span multiple geological belts across the country and include lithium prospects in Dodoma, graphite exploration licences identified through airborne geophysical surveys, rare earth element deposits in Songwe and nickel and cobalt opportunities in northwestern Tanzania.

This emerging portfolio places Tanzania within a group of African countries that could shape the future of global battery supply chains.

Lithium in Central Tanzania

Among the most promising developments is a lithium prospecting licence located within the Hombolo–Magali geological belt near Dodoma.

The area hosts pegmatite formations known to contain lithium-bearing minerals such as lepidolite and spodumene. These minerals are widely used as primary sources of lithium for battery manufacturing. The pegmatites occur within Archean rock formations that have been intruded by granitic bodies, a geological setting commonly associated with lithium mineralization worldwide.

Although exploration remains at an early stage, geological indicators suggest that the region could hold commercially viable deposits if drilling confirms resource continuity and grade.

Graphite: The Battery Anode Mineral

Graphite is another mineral attracting growing investor interest.

STAMICO has conducted airborne geophysical surveys across four graphite prospecting licences. The results show strong electromagnetic conductance anomalies, typically associated with graphite mineralization beneath the surface. 

Graphite plays a critical role in lithium-ion batteries, forming the anode component that allows the battery to store and release energy. As electric vehicle production expands globally, demand for battery-grade graphite is expected to grow sharply.

Several African countries are already capitalizing on this opportunity. Mozambique and Madagascar have become major graphite producers, and Tanzania could follow a similar path if exploration results confirm large deposits.

Rare Earths and Strategic Minerals

Beyond lithium and graphite, Tanzania also hosts rare earth element potential.

In the southwestern region of Songwe, rare earth minerals have been identified within carbonatite formations associated with the Panda Hill geological complex. Rare earth elements are essential inputs for wind turbines, electric motors, magnets and advanced electronics.

Because rare earth supply chains are currently dominated by a small number of countries, new producers are attracting increasing attention from global investors seeking diversification.

The Kabanga Belt Advantage

Northwestern Tanzania adds another strategic dimension to the country’s mineral portfolio.

Prospecting licences for nickel and cobalt lie within the Karagwe–Ankole geological belt, a mineralized corridor that extends across Tanzania, Rwanda and the Democratic Republic of Congo. The licences are located along the same geological trend as the Kabanga deposit, one of the world’s largest undeveloped high-grade nickel sulphide resources. 

Nickel and cobalt are essential for high-energy-density batteries used in electric vehicles. As automakers increase EV production, demand for these metals is expected to grow significantly.

A Strategic Opportunity

Tanzania’s advantage lies not only in geology but also in timing.

Global supply chains are under pressure to diversify away from concentrated sources of critical minerals. Governments and manufacturers are actively searching for new jurisdictions that offer both resource potential and political stability.

If exploration confirms commercially viable deposits, Tanzania could emerge as a major supplier of battery minerals within the next decade.

For investors, the opportunity lies at the exploration stage. Early partnerships in geological exploration often provide access to assets that later become cornerstone mining projects.
