Artisanal gold mining in Guinea: the governance gap and what it costs

An estimated $167 million in foregone revenues over six years. Our field diagnostic in Guinea’s artisanal gold sector quantifies the governance gap — and what it would take to close it.

The scale of the revenue gap

The most striking quantification from our diagnostic work concerned the fiscal cost of weak governance. The suspension of the export tax on artisanal gold during 2016 to 2022 contributed to an estimated US$167.3 million in foregone fiscal revenues, approximately US$27.9 million per year. This figure reflects the cumulative result of weak enforcement capacity, fragmented institutional responsibilities, and the dominance of informal governance structures at mine sites.

How informality becomes entrenched

Our fieldwork in Mandiana, Siguiri, and Kouroussa, visiting 8 artisanal mining sites, revealed a consistent picture of how informality becomes self-reinforcing. In the absence of a visible, credible administrative presence from the Ministry of Mines, customary governance fills the vacuum. Customary governance provides a form of order, but it operates on different principles than a formal regulatory system: access to mine sites is governed by relationships and payments that flow to customary authorities rather than to the state.

The traceability challenge

Gold has a particular characteristic that makes governance especially challenging: it is easily melted, transported, and commingled with gold from different sources. Our value chain mapping traced gold from extraction through artisanal treatment, sale to collectors, purchase by authorized buying counters, and export — identifying at every stage the points where gold left the formal chain.

What reform would require

Our reform package was grounded in a realistic assessment of administrative capacity and political feasibility. Three priorities: first, re-establishing a legally grounded and administratively implementable export tax mechanism; second, operationalizing the local management and oversight structures that exist in law but not in practice in Mandiana, Siguiri, and Kouroussa; third, establishing a Single Window (Guichet Unique) to centralize financial formalities and improve the traceability of payments and gold flows.

The broader lesson

Guinea's artisanal gold sector illustrates a challenge common across extractive industries in developing countries: the gap between a formal regulatory framework that looks reasonable on paper and an administrative reality in which that framework is barely operative. Closing this gap does not require sophisticated new institutions or expensive technology. It requires field presence, enforcement capacity, data collection, and incremental formalization, sustained over a period long enough for new norms to take hold.
