Aterian said its lithium-focused earn-in investment and joint-venture agreement in Rwanda with mining giant Rio Tinto is now effective, after Aterian met the required conditions.

The Africa-focused mineral exploration and development company said Tuesday that Rio Tinto has since August established its operational infrastructure and recently began field operations on the partner's HCK project.

Aterian said it will begin exploring the 2,750-hectare site and collect valuable data on the lithium, tantalum, tin, and niobium to generate preliminary resource estimates.
