Aterian Launches Responsible Tantalum and Niobium Trading Operations in Rwanda
Aterian Begins Export of Responsibly Sourced Coltan from Rwanda to Global Markets
London-listed Aterian has officially launched expanded trading operations in Rwanda with the first consignment of responsibly sourced tantalum/niobium concentrate (coltan) delivered to its global trading partner.
The company highlighted that its partnership with a major international metals and minerals trading house provides access to a well-established global sales and marketing platform.
This collaboration connects Aterian to a broad network of downstream buyers, enabling the company to scale up operations more quickly.
Before commercial sales commenced, Aterian’s trading partner conducted due diligence and product quality trials with artisanal and small-scale mining suppliers in Rwanda. These suppliers operate under standards aligned with the Organisation for Economic Co-operation and Development (OECD).
Following the successful completion of these checks, Aterian’s wholly owned Rwandan subsidiary, Eastinco, activated its responsible supply chain for tantalum and niobium and commenced commercial trading.
To support the expansion, Aterian secured a $250 000 mezzanine loan facility, which has already been fully drawn down and invested into trading operations, specifically for the acquisition of Rwandan mineral concentrates.
“The successful completion of supplier trials and compliance checks, combined with new trading capital, enables us to move forward at pace,” said CEO Simon Rollason. “We anticipate a significant increase in trading volumes in the coming weeks as we activate multiple supply relationships and expand procurement with our trade finance partners.
“This is a pivotal moment for our trading business, laying the foundation for regional growth. With risk management systems and partnerships in place, we are confident in our ability to ensure complete traceability while building a high-integrity supply chain that supports substantial volume growth and long-term revenue generation for the group.”
Aterian confirmed that all supplies are sourced in line with the International Tin Supply Chain Initiative and comply fully with OECD due diligence guidance. This involves rigorous on-site audits, mine origin verification, and conflict-free certification.
Every supplier undergoes a detailed onboarding and audit process covering operational, legal, and ethical standards. These checks are ongoing to ensure supply stability and integrity.
According to Aterian, its trading house partnership validates the company’s business model and establishes a clear pathway to creating a vertically integrated exploration and trading platform for critical minerals across East Africa.
With export-ready volumes now confirmed, Aterian announced that container-scale shipments are set to begin.
