Map a Mineral Transaction

Understand the roles, evidence and open questions in a mineral supply chain before considering a transaction.

01

Identify roles and responsibilities

Draw a simple chain showing the claimed producer, dealer or exporter, buyer, laboratory, logistics provider and relevant authorities. These roles may be held by different organisations, and a person presenting an offer may not have authority to act for every party. Note who claims to own the goods, who can authorise a sale, who would hold custody and who would receive payment. Treat this as an information request rather than an assumption that every link exists.

02

Ask what each item of evidence establishes

A photograph, a site observation, a sample test and a licence address different questions. A test result relates to the material tested and the sampling conditions; it does not by itself establish title or lawful export. Ask a qualified laboratory about suitable testing and sampling for the material. Confirm the scope and current status of relevant permissions through the appropriate issuing authorities. Keep goods, documents and the parties involved connected in the record, including unresolved gaps.

03

Include responsible sourcing

Commercial checks should be considered alongside supply-chain impacts. The OECD minerals guidance addresses risk-based due diligence for companies in mineral supply chains, including human-rights and conflict-related risks. Use the original guidance and specialist support appropriate to your role and context. A short course or worksheet cannot establish that a supplier, shipment or sourcing arrangement meets every requirement. The useful result of this exercise is a clearer set of questions and an evidence plan.
