Rio Tinto is reportedly keen to ride on the coattails of a deal in the Congo that could unlock a big piece of the world’s largest hard rock lithium deposit and save stranded shareholders of AVZ Minerals.
Government officials from the Democratic Republic of Congo and Rio Tinto higher-ups held discussions in recent weeks about developing the Roche Dure mineral resource into a lithium mine, according to Bloomberg.
Rio’s interest in the Roche Dure comes as the United States and the DRC negotiate a potential critical minerals and security partnership.
China has grown its influence in the DRC in recent years, effectively locking out Western companies from doing mining deals.
But now the DRC is entertaining a deal with the Trump Administration as the central African country struggles to suppress a Rwanda-backed rebellion in its eastern provinces.
Bloomberg last week reported that KoBold Metals, which counts the ultra-rich Bill Gates and Jeff Bezos as investors, is interested in Roche Dure. KoBold and Rio are supposedly mulling a joint venture to build and run Roche Dure.
KoBold’s proposal also reportedly aims to resolve a long-drawn dispute involving AVZ Minerals, China’s Zijin Mining Group and the DRC government, according to a letter seen by Bloomberg.
KoBold’s plan is contingent on AVZ receiving “appropriate compensation” and agreeing to transfer all its interests in the DRC.
Roche Dure was first discovered and defined by AVZ as part of its Manono mining project.
AVZ was developing the Manono— touted as “the biggest lithium discovery on the planet” — but in 2023 the DRC’s government controversially revoked and split the licence, giving Zijin the northern portion.
The value of West Perth-based AVZ, which was listed on the ASX, was savaged by the licence drama and its shares are currently delisted.
AVZ is fighting a bitter legal battle in hopes of winning back the whole deposit. Adding to the drama, The West Australian in December revealed that AVZ is under investigation by the Australian Federal Police over bribery allegations.
AVZ has denied the bribery allegations.
Rio’s purported move in the Congo comes as the Anglo Australian miner pours significant sums into lithium investments across the globe, despite the battery commodity’s depressed price.
Rio last year spent more than $10 billion to buy Arcadium Lithium and separately is building a lithium mine in Argentina. It also plans to build run lithium operation in rural Serbia, despite fierce local community opposition.
