(Ecofin Agency) - KoBold Metals, the U.S.-based mining company backed by heavyweight investors including Bill Gates and Jeff Bezos, is stepping up its campaign to secure rights to the Manono lithium deposit in the Democratic Republic of Congo (DRC), a site widely seen as having “the potential to become a large-scale, long-life lithium mine.” According to a January 2024 estimate, Manono could hold 669 million tonnes of resources grading 1.61% lithium.

On May 6, 2025, KoBold and Australia’s AVZ Minerals issued a joint statement titled Developing Manono for Peace and Prosperity, signed by their respective CEOs, Kurt House and Nigel Ferguson. The companies announced they had “reached consensus on a commercial framework to enable the rapid development of the Manono deposit.” 

The statement specifies: “This framework provides for AVZ to cede its commercial interests in the Manono lithium deposit to KoBold, at fair value.” The document further claims this agreement would allow KoBold to “quickly” mobilize more than a billion dollars “to bring Manono’s lithium to Western markets.”

But the Congolese government maintains that AVZ no longer has any rights to Manono, arguing those rights were lost when state-owned Cominière terminated its partnership with AVZ in 2022. AVZ is contesting the move before the International Court of Arbitration of the International Chamber of Commerce, where it has already secured an order for Cominière to pay €39.1 million in penalties for non-compliance with injunctions. However, the tribunal has yet to rule on the core ownership issue.

KoBold’s January offer proposes to resolve the dispute by granting “appropriate compensation” to AVZ in exchange for relinquishing its claims on Manono. The company says it is prepared to develop the southern part of the deposit, while the northern section would remain under the control of the Chinese group Zijin Mining.

Manono Lithium SAS-a joint venture 61% owned by Zijin (via Jinxiang Lithium) and 39% by Cominière-was granted an operating permit in September 2024 for part of the deposit. The company plans to begin lithium production in the first quarter of 2026.

An offer for “peace and prosperity”

So far, Congolese authorities have not commented publicly on KoBold’s offer. The May 6 joint statement suggests no favorable response yet. “AVZ has undertaken to propose to the Congolese government a temporary suspension of the ICSID arbitration proceedings to facilitate discussions,” the document states.

KoBold and AVZ may be trying to pressure Kinshasa by leveraging the current warming of US-DRC relations, considering the May 6 statement, which reads: “AVZ and KoBold are cooperating with all stakeholders, including the US government, the DRC government, and AVZ’s current development partner.”

AVZ and KoBold frame their proposal as a contribution to “peace and prosperity,” promising “thousands of well-paying jobs for the Congolese, over several decades.”

Kinshasa recently offered the Trump administration a mining agreement in exchange for its support toward resolving the ongoing conflict in Eastern DRC.  Since then, the issue has been the subject of bilateral discussions, and Washington is actively involved in the resolution process.

“A lasting peace in the eastern Democratic Republic of Congo will open the door to greater U.S. and Western citizen investment, which will create an ecosystem conducive to responsible and reliable supply chains for things like critical minerals,” declared US Secretary of State Marco Rubio on April 25, 2025, in Washington, at the signing of the “declaration of principles” for a peace agreement between the DRC and Rwanda, the main supporter of the M23 rebellion.
