Our appetite for technology is increasing.
Our global tech transition is compromised.
Sourcing minerals: the world’s most unsophisticated $100bn market.
We secure the mineral supply chain from earth to tech - with traceability, transparency and trust.

Securing the mineral supply chain from earth to tech

Our blockchain platform – with its global application – creates a digital marketplace that enables trade and compliance.

We are strategic partners at the centre of the ecosystem bringing benefits to miners, smelters, traders, tech companies and governments.

We use digital payments, blockchain and IoT – Internet of Things – to bring traceability, transparency and trust to the sector, while directly impacting 10 of the 17 Sustainable Development Goals.

Through Minexx we can satisfy the world’s appetite for technology in a fair way for people and planet.


Transforming lives through technology.


Minerals are fundamental for today’s modern society. They are in all electronics, from smartphones to electric cars.

Technology companies are under pressure from consumers, regulators and legislation to prove minerals are sourced responsibly. But the minerals which are driving our clean tech transition go through an opaque and outdated value chain. This risks funding conflict and child labour, while African countries are losing more in mineral tax evasion than they gain in foreign aid.

It is the most unsophisticated $100bn market in the world.

But now advances in technology also give us an opportunity to reshape this sector, from the moment a mineral comes out of the ground, tracing its journey into our consumer goods.


1 in 8 people in sub-Saharan African countries are dependent upon artisanal mining.

Minerals from artisanal sources:
30% of gold
30% of cobalt
50% of tantalum
80% of coloured gemstones

Eightfold increase in demand for cobalt by 2026 due to electric cars – Morgan Stanley
