The Critical Minerals Super-Cycle
The International Energy Agency projects that demand for lithium will grow 40-fold by 2040, cobalt 21-fold, nickel 19-fold, and manganese 8-fold under the Net Zero by 2050 scenario. These demand projections have redirected exploration capital from conventional precious metals targets toward the battery-minerals belt that runs from southern DRC and Zambia through Zimbabwe, Tanzania and into Ethiopia and Eritrea. East and Central Africa sit at the epicentre of this shift.
Lithium: Zimbabwe, DRC and Tanzania
Zimbabwe's Hard-Rock Lithium Boom
Zimbabwe's Archaean granites host some of the most significant pegmatite-hosted lithium deposits in Africa. Arcadia (Prospect Resources / Alita Resources), Bikita (Sinomine), Kamativi and several new discoveries are transforming Zimbabwe into a credible member of the global lithium supply chain. Hard-rock spodumene and petalite deposits offer higher-purity direct-to-refinery product pathways compared to brine deposits, and Zimbabwe's proximity to South African port infrastructure provides a logistical advantage over more remote African lithium jurisdictions.
Tanzania Lithium: The Emerging Frontier
Pegmatite-hosted lithium occurrences are increasingly documented in Tanzania's Dodoma and Singida regions, associated with Neoproterozoic granitic intrusions in the Mozambique Belt. Several junior companies have staked licence areas and commenced early-stage mapping and sampling. Tanzania's lithium potential is not yet quantified but may be significant given the structural setting.
Cobalt: DRC and Zambia
The DRC's cobalt endowment is so dominant. accounting for over 70% of global supply, that the question is not whether DRC cobalt will supply the energy transition but under what conditions and from which supply chains. The emergence of "clean cobalt" certification (Responsible Minerals Initiative, OECD Guidance) and traceability technologies (blockchain-based chain-of-custody) is creating differentiated markets where ethically sourced DRC cobalt commands a premium and drives investment into compliant, formal-sector operations.
Zambia's cobalt, produced largely as a by-product of copper refining at Chambishi, is gaining renewed attention as battery manufacturers seek to diversify supply away from DRC exposure.
Nickel: Tanzania's Kabanga and Beyond
The Kabanga Nickel project in northwestern Tanzania. held by Kabanga Nickel Limited / BHP / Tanzanian government. is one of the world's largest undeveloped high-grade nickel-cobalt-copper sulphide deposits, with an estimated resource of 58 million tonnes at 2.6% Ni, it represents a transformational project for Tanzania's mining sector. Kabanga's development, and the associated Tembo refinery concept for producing battery-grade nickel sulphate in Tanzania. signals a potential shift toward in-country beneficiation of critical minerals.
Graphite: Tanzania and Mozambique
Tanzania and Mozambique host world-class flake graphite deposits of the type required for lithium-ion battery anodes. Syrah Resources (Balama, Mozambique) and Black Rock Mining (Mahenge, Tanzania) have delineated multi-hundred-million-tonne resources at high graphitic carbon grades (>97% TGC), as battery demand scales up, these projects are transitioning from exploration to production, and creating a template for in-country graphite processing and value addition.
Technology Transformation in African Mining
Remote Monitoring and IoT
Satellite-connected sensors, drones for pit mapping and stockpile surveys, and real-time fleet management systems are being adopted by mid-tier and major operations across East Africa. The benefit is dual: reduced cost per tonne through optimised scheduling, and improved safety through remote monitoring of geotechnical risk indicators.
Green Mining Practices
Solar-diesel hybrid power for remote mine sites, electric mining vehicles (initially for underground LHDs and haul trucks), dry tailings filtration to reduce water consumption, and in-pit crush-and-convey to reduce fuel use. these technologies are moving from pilot to mainstream across African operations as power costs rise and environmental expectations tighten.
Investment Climate and Emerging Opportunities
The alignment of ESG mandates among institutional investors, green transition policy in the EU (Critical Raw Materials Act) and US (Inflation Reduction Act) with the mineral endowment of East and Southern Africa is creating the conditions for a sustained, multi-decade wave of mining investment. Countries that can offer: clear, stable mining codes; effective community engagement frameworks; functional environmental oversight; and realistic timelines for licence approvals will attract the majority of this capital.
