Aterian is building a leading African critical metals platform to supply the global clean energy transition — targeting copper, lithium, and tantalum in underexplored but highly endowed jurisdictions.
Our approach combines ethical sourcing, exploration expertise, and strategic partnerships to accelerate discovery and capital efficiency across a multi-country, multi-commodity portfolio.

Building a multi-commodity critical minerals trading platform
Eastinco, our wholly owned Rwandan subsidiary, has commenced a trial for the trading of tungsten ore and concentrates — broadening a business built on tantalum-bearing concentrates into a diversified, cash-generative trading platform.

Commodities now trading — tantalum and tungsten
Eastinco is leveraging its established procurement network, local operating infrastructure, responsible-sourcing procedures and international trading relationships to trial smaller-scale, lot-by-lot tungsten transactions with approved Rwandan suppliers — testing supplier performance, product specifications, pricing and the working capital cycle before scaling.
With China supplying around 82% of mined tungsten in 2024, supply concentration and export controls are creating diversification pressure across industrial cutting tools, mining equipment, electronics, aerospace and defence — an opportunity Eastinco is positioned to serve. The Company is also assessing further commodities including copper, tin and beryllium as it builds Eastinco into a broader trading platform.

From Our Executive Chairman
Over the past year, Aterian has increasingly moved from strategy into execution — building a diversified African critical minerals platform through exploration, strategic partnerships and operational growth. The foundations are now in place. The momentum is real, and we believe it has only just started.

Recent Validation
17km
Agdz East sits ~17km from the Bou Skour district, a producing deposit of ~53Mt at 0.8% Cu & 9g/t Ag — a structural comparison that validates Aterian's geological model.
$3–83m
Galileo Resources' recent sale of just two KCB licences — $3m upfront plus up to $80m contingent — underscores the strategic value of ground in the belt, where Aterian holds 11 licences across ~5,200 km².
140%
Expansion of the high-resolution ground magnetic survey at Agdz, identifying multiple priority targets along kilometre-scale fault corridors ahead of trenching and drilling.
More From Our Chairman
A high-resolution drone magnetic survey is now underway in Botswana over our two highest-priority Kalahari Copper Belt licences — the data will feed directly into Lithosquare's AI platform to rank drill targets beneath the region's sand cover.
While attention has focused on HCK's lithium-bearing pegmatites, drilling has also confirmed significant tantalum mineralisation — a metal essential to AI data centres, electronics, semiconductors and aerospace.
Our strategy is clear: discover, de-risk, demonstrate value, then partner with world-class operators to unlock that value for shareholders — alongside scaling Eastinco, our Rwandan trading business.
