Africa to Pilot Innovative Bond to Formalise Artisanal Mining Sector

A new sustainability-focused financing model aimed at integrating informal miners into formal supply chains is set to be piloted in Africa this year, marking a significant step toward transforming the continent’s artisanal mining sector.

The initiative, developed by Canada-based advisory firm Veridicor in partnership with Zambia’s Metalex Commodities, centres on a “stakeholder prosperity bond” designed to formalise artisanal and small-scale mining while improving social and environmental outcomes.

Artisanal mining supports the livelihoods of millions across Africa but largely operates outside formal systems, often taking place near industrial mining sites. This has historically created tensions with large-scale operators, contributed to environmental degradation, and limited government revenue collection.

Rather than displacing these miners, the proposed bond structure seeks to integrate them into regulated value chains. The model links investor returns to measurable social and environmental improvements, including better working conditions, reduced pollution, and stronger economic benefits for local communities.

The first issuance, expected before the end of the year, aims to raise between $100 million and $200 million. Proceeds will be used to support the integration of artisanal miners through formal offtake agreements, shared infrastructure, and access to equipment—allowing them to operate more efficiently and sustainably.

Zambia, Africa’s second-largest copper producer, provides a natural testing ground for the initiative, with tens of thousands of artisanal miners active across the country, particularly around industrial mining licences. Under the model, larger mining companies act as anchor partners, supporting the bond structure while benefiting from more stable and transparent ore supply.

The approach is designed to create shared value across the ecosystem. Industrial operators gain access to additional feedstock under regulated conditions, while artisanal miners benefit from fair pricing and safer, more structured working environments.

Beyond Zambia, the model is already being considered for expansion into the Democratic Republic of Congo and Ghana, both of which have significant artisanal mining sectors.

As global investors increasingly prioritise environmental, social, and governance (ESG) outcomes, the bond could offer a scalable solution to one of the mining industry’s most persistent challenges—bridging the gap between informal activity and formal, sustainable development.
