Structured sourcing programme from artisanal mining operations
A network of artisanal mining cooperatives required structured procurement with documented responsible-sourcing compliance. The Project Office established a chain-of-custody programme with due-diligence assessments and documented handover at each stage.
Project Profile
Sector: Artisanal and small-scale gold sourcing — export-grade refinement pipeline Scope: Structured aggregation, assay validation, chain-of-custody documentation and responsible-sourcing compliance for a recurring supply programme across active ASM corridors in Ghana Client Tier: Tier-1 Institutional Refinery — European operations Programme Duration: Ongoing; initial structured pipeline established over a multi-month mobilisation phase
The Sourcing Challenge
Artisanal and small-scale mining corridors in Ghana generate material of genuine metallurgical value — but the path from mine-site output to a Tier-1 refinery’s accepted intake is rarely linear. The instructing client required gold supply that satisfied not merely assay thresholds, but the full documentary architecture that responsible-sourcing compliance frameworks demand: origin traceability, chain-of-custody continuity, conflict-minerals due diligence, and consistent lot-level assay data.
The challenge was structural. ASM supply is inherently fragmented — sourced across multiple operators, varying in purity, inconsistently documented, and exposed to chain-of-custody breaks at each aggregation point. Any single gap in the documentation trail renders a lot commercially inadmissible to institutional buyers regardless of its metallurgical quality. The client’s compliance desk had rejected prior supply attempts from the corridor precisely on documentation grounds, not assay grounds.
Approach
Ghana Metals deployed a disciplined, process-first sourcing structure built specifically for this client’s intake requirements.
Aggregation discipline was established at source level — not at the point of export. Field-level documentation protocols were embedded with aggregation partners, creating verifiable lot-origin records from the point of acquisition rather than retrospectively.
Assay validation was conducted at each aggregation stage, with independent cross-verification prior to consolidation. No material advanced in the pipeline without a corresponding, traceable assay record aligned to the client’s minimum specification.
Chain-of-custody documentation was maintained as a continuous thread — each transfer, each custody handover, each transport movement logged and reconcilable at audit. The documentation architecture was designed to satisfy the client’s internal compliance team and external regulatory review simultaneously.
Responsible-sourcing compliance review was conducted against applicable frameworks governing conflict-minerals due diligence and ASM operator conduct. Only operators meeting the compliance baseline were retained within the sourcing network.
Trade facilitation and export documentation were coordinated in alignment with Ghanaian regulatory requirements, ensuring the material arrived at the refinery intake desk with a complete, audit-ready dossier.
Outcome
The client’s compliance desk accepted the initial consignment without remedial documentation requests — the first time supply from this corridor had cleared intake review without exception. The programme has since continued on a recurring basis, with the documentation architecture functioning as a standing compliance framework rather than a consignment-by-consignment construction.
The sourcing network itself has been refined progressively, with operators demonstrating consistent compliance posture consolidated into a preferred-tier structure that reduces aggregation time without sacrificing documentary rigour.
What This Project Demonstrates
Artisanal corridors are not inherently incompatible with institutional supply chains — but they require the sourcing discipline that most operators do not provide. The decisive variable is process architecture: documentation built from the source point outward, assay validation conducted continuously rather than terminally, and compliance review embedded as a structural feature rather than a late-stage filter.
Ghana Metals exists precisely for this work. Where supply chains require both metallurgical reliability and institutional-grade documentation, the discipline applied here is the standard we bring to every programme across Ghana and Togo.
