The Lithium Triangle of Africa: Zimbabwe, Namibia, and DRC Exploration Trends

As the global demand for electric vehicles and renewable energy storage surges, lithium has become one of the world’s most strategic minerals. Traditionally dominated by the “Lithium Triangle” of South America—Chile, Argentina, and Bolivia—the focus is now expanding to Africa. A new “Lithium Triangle” is emerging on the continent, anchored by Zimbabwe, Namibia, and the Democratic Republic of Congo (DRC).

Africa’s mineral wealth has long been recognized, but in recent years, these three nations have begun to attract global attention for their high-grade lithium reserves and favorable geology for large-scale production. Alongside this growth, the emphasis on sustainable exploration practices—such as responsible drilling, efficient core sampling, and the use of recycled plastic core trays—is redefining how mining companies operate on the continent.

This article explores the geology, current exploration activities, and sustainable innovations shaping Africa’s lithium boom—along with the pivotal role that core storage and handling play in ensuring reliable geological data and environmentally responsible mining.

The Global Lithium Context

Lithium is often called “white gold” for the 21st century. It is an essential component in lithium-ion batteries that power electric vehicles, smartphones, and grid-scale energy storage systems. According to the International Energy Agency (IEA), global lithium demand could increase sixfold by 2030, driven by electric vehicle production and energy transition goals.

While South America still holds more than 50% of the world’s lithium resources, Africa’s untapped potential is now impossible to ignore. The continent’s combination of pegmatite deposits, favorable mining laws, and growing infrastructure investment has made it a promising frontier for lithium exploration.

Zimbabwe: Africa’s Lithium Powerhouse

Zimbabwe has emerged as the leading lithium producer in Africa and one of the top five globally. Its lithium wealth is primarily concentrated in spodumene- and petalite-bearing pegmatites found in the Bikita, Arcadia, and Zulu regions.

Key Projects:

• Bikita Mine (Masvingo Province): Africa’s oldest lithium operation, in production since the 1950s, now undergoing expansion to increase capacity for lithium hydroxide supply to EV markets.

• Arcadia Project (near Harare): One of the world’s largest hard-rock lithium deposits, developed by Prospect Resources and later acquired by Zhejiang Huayou Cobalt. The mine’s estimated reserves exceed 70 million tonnes of lithium ore.

• Zulu Project (Fort Rixon): Managed by Premier African Minerals, the Zulu deposit has attracted attention for its consistent lithium grade and strategic position in the regional supply chain.

Zimbabwe’s geology provides the ideal environment for economic lithium extraction—shallow pegmatite bodies, relatively low stripping ratios, and stable mineralogy.

Sustainability in Practice:

As global investors demand ESG compliance, Zimbabwean operations are beginning to adopt greener exploration techniques. The use of recycled plastic core trays for sample storage ensures long-term integrity of lithium-bearing core samples under harsh tropical climates, where humidity and temperature fluctuations are constant challenges. Plastic trays also resist chemical degradation caused by spodumene or drilling fluids, unlike traditional wooden boxes that rot and contaminate samples.

Moreover, new processing plants in the country are exploring solar-powered operations, aligning lithium production with clean-energy principles.

Namibia: Desert Lithium and New Frontiers

Namibia, often associated with uranium and diamond mining, is fast becoming a lithium exploration hub. The Namibian pegmatite belt, stretching across Erongo and Hardap regions, contains numerous spodumene-bearing pegmatites similar to those found in Zimbabwe and Australia.

Notable Projects:

• Desert Lion Energy Project: Located near Karibib, this site has been a focal point of Namibia’s lithium development. The project, led by Lepidico Ltd, includes both mining and lithium hydroxide conversion facilities designed for battery-grade production.

• Uis Mine (by AfriTin Mining): Originally a tin mine, Uis is being revived with a focus on lithium and tantalum co-production. Exploration drilling has revealed significant lithium mineralization within old pegmatite structures.

• Kaoko Belt Exploration: New discoveries in northern Namibia suggest potential for large-scale lithium-bearing pegmatites that could reshape the nation’s resource portfolio.

Geological and Environmental Considerations:

Namibia’s semi-arid environment presents unique challenges—intense UV radiation, high temperatures, and limited water resources. For geologists and exploration engineers, sample preservation becomes a top priority.

UV-resistant plastic core trays are invaluable in such conditions, ensuring that geological core samples remain stable during long-term outdoor storage. The lightweight and stackable design of these trays improves logistics across vast exploration sites, reducing both cost and environmental impact.

Namibia’s government has also taken a progressive stance toward sustainable mining. With strong institutional frameworks and renewable energy initiatives, it offers a blueprint for low-carbon lithium production.

DRC: Manono and the Future of African Lithium

The Democratic Republic of Congo is already synonymous with cobalt—the metal that powers most lithium-ion batteries. Now, it is positioning itself as a dual supplier of cobalt and lithium, thanks to the Manono Project, one of the world’s most promising hard-rock lithium deposits.

The Manono Project:

Located in Tanganyika Province, the Manono deposit is hosted within a 13 km-long pegmatite belt with exceptionally high spodumene content. Preliminary resource estimates indicate over 400 million tonnes of lithium-rich ore, placing it among the largest undeveloped deposits globally.

The project, led by AVZ Minerals, has attracted significant international investment. Its scale could make the DRC a key player in the global lithium supply chain—complementing its existing dominance in cobalt.

Sustainable Exploration Efforts:

In tropical regions like Manono, managing core sample degradation is critical. Intense humidity, heavy rainfall, and logistical constraints make plastic core trays essential. Unlike wood, plastic trays resist rot, termite damage, and moisture absorption, keeping samples intact from field to laboratory.

Many exploration teams in the DRC are now integrating solar-powered core sheds and recycled core tray systems to reduce their carbon footprint. The combination of sustainable materials and renewable energy aligns with international ESG expectations for responsible mining investments.

The Role of Geological Core Trays in Lithium Exploration

Across Africa’s lithium triangle, accurate geological data determines the success of every project. Core samples represent the physical evidence of mineralization, and their preservation directly influences assay quality, mine planning, and investor confidence.

Proper core storage and handling ensure:

• Data Integrity: Core trays maintain exact sample orientation and depth sequence, critical for geological modeling.

• Durability: UV- and impact-resistant plastic trays prevent damage from harsh environments during transport and storage.

• Sustainability: Trays made from recycled plastic support ESG targets and reduce landfill waste from traditional materials.

• Operational Efficiency: Stackable, lightweight designs optimize space, logistics, and reduce fuel consumption in remote areas.

In exploration hubs such as Harare, Karibib, and Manono, the transition from wooden to recycled plastic trays is already evident. Mining teams report lower breakage rates, easier handling, and longer storage life, demonstrating that sustainability and efficiency can go hand in hand.

The Broader ESG and Economic Outlook

Africa’s lithium expansion coincides with a global shift toward ESG-driven mining. Investors increasingly prioritize operations that minimize environmental impact, ensure community benefits, and uphold ethical sourcing standards.

• Environmental: Solar-powered mining operations, efficient water recycling systems, and the adoption of eco-friendly sampling materials are reducing emissions.

• Social: Lithium projects create skilled employment opportunities, while community energy initiatives help electrify remote areas.

• Governance: Transparent reporting and traceable supply chains are now prerequisites for international partnerships, especially with European and North American battery manufacturers.

By aligning exploration practices with ESG principles—such as using recycled plastic core trays and renewable energy—African lithium projects gain a competitive edge in global markets increasingly focused on sustainability.

Africa’s Role in Global Battery Supply

The coming decade will see Africa’s lithium resources integrated into the global energy transition. As electric vehicle adoption accelerates, the continent’s role will expand from raw material supplier to value-added producer, including battery-grade lithium hydroxide refining.
