Aterian PLC Discovers High-Grade Lithium Deposits in Rwanda

Strategic Insights -

Aterian PLC, a UK-based critical minerals exploration company, has made a significant discovery in Rwanda, finding high-grade lithium deposits following a drilling exercise in collaboration with Rio Tinto Mining and Exploration Ltd. This breakthrough has significant implications for the region's mining sector, which already contributes approximately 3% to Rwanda's economic output and employs over 72,000 people. The discovery was announced in a statement on July 10, confirming the presence of high-grade lithium mineralisation and demonstrating the prospectivity of the HCK Project.

Key Takeaways:

  • Aterian PLC and Rio Tinto Mining and Exploration Ltd have discovered high-grade lithium deposits in Rwanda through a joint drilling exercise.
  • The HCK Project, a joint venture between the two companies, has identified 19 pegmatite zones for lithium, cesium, and tantalum on 2,750 hectares of land in Southern Province.
  • One drill hole, MWOG0002, reached a depth of 174.6 meters and uncovered a 6.9-meter section of lithium-bearing rock grading 2.11% lithium.
  • Rio Tinto has exercised its Stage 1 earn-in rights, allowing it to own a 51% interest in the HCK license, which will increase to 75% upon investing $7.5 million over three years.
  • A comprehensive technical review is currently underway to determine the optimal next phase of exploration, with a JV decision anticipated by the end of 2025.
  • The discovery of high-grade lithium deposits in Rwanda highlights the significant potential of the region's mining sector, which already contributes approximately 3% to Rwanda's economic output and employs over 72,000 people.
