Rwanda is fast becoming a cornerstone of East Africa’s mining landscape. It combines clear rules, predictable permitting, and an active push for responsible, traceable supply. For critical raw materials like tin, tantalum, niobium and lithium, that mix is hard to beat.

 Clear permitting with defined steps and responsive oversight.

 Pro-investment stance with an emphasis on responsible operations and traceability.

 Consistent policy environment that reduces operating risk.

 Young workforce with growing technical training and local contractor capability.

 Upgrades across key mining regions, plus reliable power in growth corridors.

 Efficient routes to international markets via Dar es Salaam and Mombasa.

Demand for energy-transition and high-tech metals is rising. Rwanda offers the right fundamentals to explore, develop and move product through compliant, auditable supply chains.

 Tantalum and niobium in the near term, with lithium evaluation continuing.

 Data-led exploration tied to partner-funded development where appropriate.

 Alignment with responsible sourcing frameworks to support downstream buyers.

 Rwanda gives Aterian a stable base, efficient routes to market, and the ability to grow a responsible critical-minerals platform.

Our Rwanda portfolio includes two strategically important projects:

Aterian controls more than 3,000 hectares of highly prospective ground in Rwanda, targeting critical technology metals including tantalum, niobium, tin, tungsten and lithium. Our approach blends data-led exploration, partner-enabled development and a compliant trading footprint to unlock value in one of East Africa’s most investable mining jurisdictions.

 2,750 ha in southern Rwanda with a comprehensive exploration dataset from mapping, geochemistry, geophysics and core drilling. Current focus is tantalum–niobium targeting with lithium under evaluation.

 Western Rwanda, 350 hectares. Multi-commodity targets including Li, Ta, Nb, Sn and W.

 Direct exploration, selective M&A/licence acquisition, and partnerships with capable local operators and near-production assets.

 Our Rwanda trading licence enables strategic buy-ins, access to by-product credits and offshore pricing options to enhance portfolio flexibility and near-term revenues.

 Alignment with recognised traceability frameworks to support downstream ethical-sourcing requirements.

Aterian’s Rwanda platform is built to meet rising demand for responsibly sourced critical minerals through disciplined exploration, capital-aware development and transparent routes to market.

Advancing tantalum and niobium with lithium evaluation on a fully owned, data-rich licence

Located 65 km southwest of Kigali, the HCK Project is a 2,750-hectare exploration licence 70% owned by Aterian. 

Following the conclusion of a prior farm-in, Aterian retains a comprehensive exploration dataset from mapping, geochemistry, ground geophysics and diamond drilling. 

This provides a strong evidence base to prioritise tantalum–niobium targets while continuing to assess identified lithium mineralisation.

Focus: tantalum and niobium priority; lithium under evaluation

Dataset: inherited multi-method programme including diamond drilling

Status: data integration, target ranking and next-phase planning

In Rwanda, Aterian is building a secure, institutional-grade supply chain for the metals powering tomorrow's technology. 

Focusing primarily on tantalum, niobium, and lithium - critical components for advanced electronics and AI infrastructure - Aterian combines active, cash-generating mineral trading with data-led exploration in one of East Africa's most transparent and stable mining jurisdictions.

Advancing tantalum and niobium, assessing lithium and strengthening Rwanda’s role in Aterian’s portfolio.

Advancing a multi-commodity target area in western Rwanda

The 350 hectare and 100% owned Musasa Project, sits in a highly prospective district in western Rwanda. 

Target commodities include lithium, tantalum, niobium, tin and tungsten.

Consolidate and review historic and recent datasets

Define priority targets and phase the next field programme

Rwanda is a recognised leader in the 3Ts, tantalum, tin and tungsten, with growing interest in its lithium potential. A modernised mining code, political stability, and established traceability frameworks create an investor-friendly setting for critical minerals.

Clear licensing process with predictable timelines and policy continuity

Internationally recognised traceability systems that support ethical sourcing

Improving infrastructure and access to export corridors via Dar es Salaam and Mombasa

Skilled, youthful workforce with expanding technical training

Focus on tantalum and niobium, with lithium evaluation continuing in LCT pegmatite systems

Trading Licence enables strategic buy-ins, offshore pricing options, and access to by-product credits

Data-led exploration tied to partner-funded development where appropriate, keeping programmes capital-aware

Rising demand for tantalum in electronics and electric vehicles, driven by capacitor and superalloy applications

Ongoing need for traceable, responsibly sourced 3T supply to meet downstream compliance requirements

With supportive regulation and underexplored geology, Rwanda is well positioned to grow as a critical-minerals centre, and Aterian’s combined exploration and trading footprint is set up to convert that potential into value.
