The problem
Institutional buyers need a documented, HSE-disciplined source for assay & quality verification.
Our approach
Assay & Quality Verification
Assay & Quality Verification delivered to institutional standard — structured procurement, chain-of-custody discipline, documented handover.
The Challenge
Precious metals move through complex, multi-party supply chains where a single gap in verification discipline can undermine an entire transaction — from the mine gate to the refinery intake. In Ghana and Togo, where artisanal and small-scale mining activity intersects with institutional trade flows, the assay and quality verification stage is not a formality. It is the point at which material representation meets documented reality, and where disputes are made or avoided.
Refineries, institutional investors and export operations require more than a weight declaration and a purity estimate. They require structured, traceable verification — a process that holds under scrutiny from compliance officers, trade financiers and regulatory bodies alike. Without it, procurement decisions are made on incomplete information, counterparty risk accumulates, and chain-of-custody integrity breaks down at the precise moment it is most needed.
The sector demands verification conducted not as a transactional checkpoint but as a professional discipline — with documented methodology, calibrated instrumentation, and a clear handover record that survives audit review.
The Ghana Metals Solution
Ghana Metals applies a structured assay and quality verification process designed for institutional procurement chains. Each engagement begins with documented intake — material provenance, declared specification, and counterparty records — before any analytical work commences. This sequencing is deliberate: verification without documented context produces a number, not a finding.
Analytical work is conducted using calibrated instrumentation appropriate to the material type and the precision requirements of the receiving institution. Results are reported in a format aligned with refinery intake standards and trade finance documentation requirements — not summary certificates, but structured verification records that carry the full weight of a traceable process.
Throughout the engagement, chain-of-custody is maintained as a non-negotiable condition. Sample handling, analytical sequencing and results documentation follow a defined internal protocol, ensuring that the verified record Ghana Metals issues can be relied upon at every subsequent stage of the transaction.
Process and Verification Specification
- Documented material intake with provenance recording and counterparty identification prior to analytical commencement
- Calibrated fire assay and XRF-based analytical methods selected to match material type and institutional precision requirements
- Chain-of-custody maintained across all sample handling stages — intake, preparation, analysis and results documentation
- Structured verification reports formatted to refinery intake and trade finance documentation standards
- Responsible-sourcing compliance checks integrated into the verification workflow, not treated as a separate advisory layer
- Discrepancy protocol activated where declared specification diverges materially from analytical findings, with documented escalation and client notification
Typical Engagement Profile
A typical verification engagement spans a defined consignment or procurement tranche — managed across the supply chain corridor in Ghana or Togo as the transaction requires. Clients include refineries conducting intake due diligence, institutional investors commissioning independent verification of purchased material, banks requiring documented assay records to support trade finance facilities, and export operations preparing documentation packages for cross-border regulatory clearance. Timeline is calibrated to the transaction’s commercial requirements, with documentation structured for immediate integration into the client’s compliance or procurement workflow.
Outcomes
- Institutional-grade verification records that withstand audit review by compliance officers, trade financiers and regulatory bodies
- Reduced counterparty risk through documented, independent analytical findings rather than reliance on self-declared material specifications
- Chain-of-custody continuity from material intake through to verified results — traceable at every stage
- Responsible-sourcing compliance evidence integrated into the verification record, supporting downstream reporting obligations
- A structured discrepancy protocol that protects client interests when declared and verified specifications diverge
