Beneath the red laterite soil of Tanganyika Province in the southeastern Democratic Republic of Congo lies a geological formation that could reshape the global energy transition. The Manono-Kitotolo pegmatite deposit — a lithium-bearing ore body stretching roughly 13 kilometres in length — contains an estimated 401 million tonnes of ore grading at 1.65% lithium oxide. In raw terms, that makes it one of the largest hard-rock lithium deposits ever discovered on earth.
This is not speculative geology. These are measured and indicated resources, confirmed by multiple independent technical assessments. And they sit in a country that already dominates the battery metals supply chain through its unassailable position in cobalt production.
The Scale of the Opportunity
The numbers are staggering by any measure. At current lithium prices, the Manono deposit alone has an estimated in-ground value exceeding $15 billion. But the DRC's lithium story extends beyond a single deposit. Geological surveys have identified additional lithium-bearing pegmatites across Tanganyika and Haut-Lomami provinces, suggesting that the country's total lithium endowment could be significantly larger than current estimates indicate.
What makes the DRC's lithium particularly strategic is context. This is not a country entering the mining industry for the first time. The DRC has decades of experience in industrial-scale mineral extraction, an established mining code (revised in 2018), existing relationships with global commodity traders, and — critically — the world's largest cobalt reserves sitting alongside its lithium deposits.
That combination matters enormously. A lithium-ion battery requires both lithium for the cathode and cobalt for stability and energy density. A country that can supply both from geographically proximate deposits offers something no other nation can: the possibility of a vertically integrated battery metals hub on African soil.
The Investment Pipeline
Capital is flowing, though not without complications. AVZ Minerals, the Australian company that holds the majority stake in the Manono project, has seen its journey illustrate both the promise and the peril of DRC mining investment. After completing a definitive feasibility study that valued the project at over $5 billion, AVZ became embroiled in a complex ownership dispute involving competing claims from Chinese interests and the DRC's state mining company, Gécamines.
The dispute, which has involved arbitration proceedings in Paris and interventions from the DRC government, has delayed development but not deterred interest. If anything, the intensity of the competition for Manono underscores the project's strategic value. Multiple parties want control precisely because the economics are so compelling.
Beyond Manono, the investment pipeline is expanding rapidly. Tantalex Lithium has acquired exploration rights in adjacent concessions. Zijin Mining, the Chinese metals giant, has secured positions in copper-cobalt projects that sit near lithium-bearing formations. CATL, the world's largest battery manufacturer, has established offtake relationships that could see DRC lithium flow directly into Chinese EV battery production.
The total investment pipeline across all DRC lithium projects is estimated to exceed $15 billion through 2030 — a figure that would make lithium the country's third-largest mining sector after copper and cobalt.
The Processing Question
Raw lithium ore is worth relatively little compared to processed lithium compounds. Lithium hydroxide and lithium carbonate — the forms required by battery manufacturers — trade at significant premiums to spodumene concentrate, the unprocessed mineral. The value chain looks something like this: mining spodumene ore generates perhaps $800-1,200 per tonne; converting it to battery-grade lithium hydroxide captures $15,000-25,000 per tonne depending on market conditions.
Historically, this processing has occurred almost exclusively in China, which controls approximately 65% of global lithium refining capacity. African countries have exported raw minerals and imported finished batteries — a pattern that President Félix Tshisekedi has described as "the old colonial model wearing new clothes."
The DRC government is now mandating local processing requirements. New mining permits include obligations to establish beneficiation facilities within the country. The goal is not merely to export spodumene concentrate to Shanghai, but to build lithium processing plants in Lubumbashi, Likasi, or Kolwezi — cities that already host copper and cobalt smelters.
The ambition faces real obstacles. Reliable electricity supply remains a challenge in the DRC despite the country sitting atop the Congo River system, which has the hydroelectric potential to power the entire continent. Transport infrastructure — the roads, rail links, and port access needed to move processed lithium to global markets — requires massive investment. Skilled labour for lithium processing is scarce.
Geopolitical Dimensions
The DRC's lithium reserves have attracted attention from every major power engaged in the energy transition. The United States, through its Minerals Security Partnership, has identified DRC lithium as a priority for diversifying supply chains away from Chinese dominance. The European Union's Critical Raw Materials Act lists lithium as a strategic resource and names the DRC as a key source country.
China, already the DRC's largest trading partner and mining investor, is moving to secure additional lithium positions. Chinese companies now control or have significant stakes in approximately 15 of the DRC's 19 largest cobalt mines. The pattern is extending to lithium, with Chinese firms offering infrastructure investment — roads, bridges, processing plants — in exchange for long-term mineral offtake agreements.
This great power competition creates both opportunity and risk for the DRC. On one hand, competitive demand from multiple bidders gives Kinshasa negotiating leverage. On the other, it creates political pressures and the potential for the country's mineral wealth to become a proxy for broader geopolitical contests.
The Labour and Governance Challenge
Any honest assessment of DRC mining investment must address the governance environment. The country ranks 170th out of 180 on Transparency International's Corruption Perceptions Index. Mining contracts have historically been opaque, with revenues disappearing into elite networks rather than reaching public coffers or local communities.
The 2018 Mining Code revision attempted to address some of these issues by increasing royalty rates, mandating community development funds, and creating a state-owned strategic minerals company. Implementation has been uneven. Some provinces have seen genuine improvements in revenue transparency; others remain captured by entrenched interests.
The artisanal mining sector presents additional challenges. While large-scale lithium mining (unlike cobalt) is less amenable to artisanal extraction due to the processing requirements, the influx of mining activity into new regions creates land-use conflicts, displacement pressures, and environmental risks that require careful management.
The Investment Thesis
For investors, the DRC lithium story presents a classic frontier market dilemma: extraordinary resource potential weighed against significant political, logistical, and governance risks. The question is not whether the lithium is there — it demonstrably is — but whether the institutional environment will allow its extraction and processing in a manner that generates returns for shareholders while delivering benefits to the Congolese people.
The bull case rests on structural demand. Global lithium demand is projected to triple between 2025 and 2030, driven by EV adoption mandates in Europe, China, and increasingly the United States. Supply is constrained — new mines take 5-7 years to develop. The DRC's reserves are among the highest-grade in the world, offering lower extraction costs per tonne of lithium content.
The bear case centres on execution risk. Ownership disputes have delayed multiple projects. Infrastructure deficits add to operating costs. The regulatory environment, while improving, remains less predictable than Australia, Chile, or Argentina — the DRC's main competitors in the lithium space.
What is clear is that the DRC's lithium reserves represent one of the most consequential mineral discoveries of the 21st century. Whether the country captures the full value of this endowment — or watches it extracted on terms set by others, as has happened too often with African resources — will depend on decisions being made right now in Kinshasa, Lubumbashi, and the boardrooms of companies competing for a piece of the $15 billion prize buried beneath Tanganyika's red earth.
