New explorations in Rwanda’s eastern province have revealed a significant lithium deposit, with preliminary estimates suggesting at least 30 million tons of ore at 1% lithium oxide—enough to position the country as a potential leader in Africa’s burgeoning lithium industry.
A Promising Discovery
Deep inside the cult mine in Rwanda’s eastern province, miners and geologists are drilling into what could be one of the continent’s largest lithium reserves. The site, operated by Trinity Metal Group, a major player in Rwanda’s mining sector, has already shown highly encouraging results.
Peter Galata, CEO of Trinity Metal Group, stated that initial drilling indicates a resource of 50 to 100 million tons, with potential for further expansion. “If you compare it to other lithium deposits around the world, it’s in the top 10 for sure,” Galata said. “We believe there’s great potential here.”
Lithium: A Game-Changer for Rwanda’s Economy
Lithium, a critical mineral for electric vehicle batteries and renewable energy technologies, could transform Rwanda’s mining sector. The discovery comes as the government pushes to increase mineral exports, which brought in $1.7 billion in 2024—making mining the country’s top export sector. Officials aim to raise annual mining revenues to $2.17 billion by 2029.
The Director of Mine Exploration at the Rwanda Mining Board, emphasized the country’s focus on attracting investment and expanding exploration. “We have demarcated 10 new mining blocks to boost the sector,” she said.
Next Steps: Commercial Mining in 3-5 Years
While Rwanda’s lithium potential is substantial, experts stress that attracting global investors and adopting advanced mining technologies will be crucial. Currently, the Nunga deposit alone holds an estimated 157,000 tons of lithium metal, with further exploration expected to reveal more reserves.
Officials predict that commercial lithium mining could begin within three to five years, marking a major milestone in Rwanda’s industrial development. As global demand for lithium surges, this discovery could place Rwanda at the forefront of Africa’s green energy supply chain.
