Mineral Sourcing Problem

Technology companies are under pressure from consumers and regulators to prove their minerals are sourced responsibly. With seven stages from artisanal mine to manufacturer mineral origin data is not trustworthy and tech companies are powerless to improve the situation for miners.


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 

Legal requirement for tech companies to prove minerals are responsibly sourced in EU and US.
