A new financing instrument aimed at integrating artisanal and small-scale miners into formal supply chains is set to be piloted in Africa, marking a notable shift in how the sector is approached.
Developed by Canada-based advisory firm Veridicor in partnership with Zambian copper producer Metalex Commodities, the proposed “stakeholder prosperity bond” seeks to align investor returns with social and environmental outcomes rather than production volumes.
The initiative targets one of the mining industry’s most persistent challenges. Artisanal mining supports livelihoods for hundreds of millions globally, yet in Africa it largely operates outside formal frameworks, often overlapping with industrial concessions. This has historically resulted in lost revenue for governments, operational disruption for mining companies, and ongoing environmental and safety concerns.
Rather than displacing informal miners, the bond structure is designed to bring them into regulated value chains. Proceeds from an initial issuance, expected to raise between $100 million and $200 million, will be used to fund formal offtake agreements, shared infrastructure, and access to equipment.
Under the model, industrial mining companies act as anchor participants, providing balance sheet support while securing more stable and transparent ore supply. Artisanal miners, in turn, gain access to fair pricing and improved working conditions through formalisation and licensing.
A key feature of the instrument is its performance-linked structure. Returns are tied to predefined environmental and social metrics, with interest rates adjusting according to outcomes such as reduced pollution, improved safety standards, and broader community benefits.
Zambia, Africa’s second-largest copper producer, has been selected as the initial test case, reflecting both the scale of its artisanal mining activity and the proximity of informal operators to established mining assets. The model is also being considered for expansion into the Democratic Republic of Congo and Ghana.
For operators, the approach offers a pathway to mitigate longstanding tensions with informal miners while improving supply chain visibility. For governments, formalisation presents an opportunity to capture revenue from previously unregulated activity. For investors, the structure introduces a new ESG-linked instrument tied to measurable outcomes in a complex operating environment.
While the success of the pilot will depend on execution, the concept signals a broader shift in industry thinking. Formalisation is increasingly being framed not as an enforcement issue, but as a financing and integration challenge, with capital markets positioned as part of the solution.
