Highlights

  • First consignment of responsibly sourced tantalum-niobium (coltan) shipped through global trading partner.

  • US$250,000 mezzanine loan secured to accelerate trading operations in Rwanda.

  • All supplies fully compliant with OECD and ITSCI responsible sourcing standards.

Aterian plc (LSE:ATN), the critical mineral exploration and development company, announced the commencement of expanded trading operations in Rwanda, marked by the transfer of its first consignment of responsibly sourced tantalum-niobium concentrate (commonly known as coltan) to its international trading partner.

The partnership with a global metals and minerals trading house provides Aterian with established sales channels and access to a wide downstream buyer network. 

Responsible Sourcing Framework

Aterian confirmed that all mineral supplies handled by its wholly owned Rwandan subsidiary, Eastinco Ltd, are fully compliant with the International Tin Supply Chain Initiative (ITSCI) and OECD Due Diligence Guidance. The company has conducted extensive on-site audits, mine origin verification, and conflict-free checks to establish a transparent supply chain.

The onboarding process for artisanal and small-scale mining suppliers included thorough reviews of operational, legal, and ethical standards.

Financial Support and Expansion

To accelerate its trading expansion, Aterian secured a US$250,000 mezzanine loan facility. The capital, which has been fully drawn, is being used to finance the acquisition of responsibly sourced concentrates in Rwanda.

Key terms of the loan include:

  • Principal: US$250,000

  • Interest & Fees: 20% interest plus 2% trading fees

  • Term: Initial three months, extendable quarterly by agreement

  • Guarantee: Aterian plc guarantees the performance of Eastinco Ltd

The loan proceeds are now fully deployed, supporting initial export volumes, with container-sized shipments expected to commence shortly.

Market Positioning and Growth Strategy

The company highlighted that the partnership with its global trading house validates its business model and demonstrates the commercial pathway to building a vertically integrated critical minerals platform across East Africa. 

Coltan, the mineral group comprising tantalite and columbite, is a primary source of tantalum and niobium. Tantalum is critical for capacitors and high-performance resistors used in smartphones, laptops, and aerospace technology, while niobium is key to advanced steel alloys, superconductors, and specialised electronics.

Outlook

Export sales through Aterian’s trading partner are set to scale, with container-sized consignments marking the next phase of operations. The company will provide further updates on trading performance and supply expansion in due course.

Aterian stated that its focus on responsible sourcing, combined with global trading links, positions it to meet growing international demand for critical minerals while ensuring compliance with ESG-aligned procurement standards.
