Counterparty due diligence
Supplier identity, authority to act, relationship to source, applicable commercial, tax and banking information, and risk indicators requiring review.
Responsible sourcing & traceability
Know the counterparty. Verify the mine. Preserve the lot identity.
For us, traceability begins at source, not at export. We link supplier due diligence, mine verification, dispatch and receiving controls, production traceability, export documentation and final reconciliation into one evidence chain.
Source competency
Four control layers.
Our objective is simple: create an evidence chain we can reconstruct, rather than rely on a single declaration or document.
Mine & source verification
Applicable concession or right, location, evidence of activity or stock, mineral characteristics and consistency between supplier, mine and offered material.
Chain of custody
Authorized dispatch, vehicle, origin, weighbridge, sample, receiving lot, process batch, blend, packing, container, seal and export lot.
Reconciliation & escalation
Compare mass, grade, moisture, shipment identity, buyer assay and settlement; investigate material deviations before closure.
Field controls
Evidence should follow the material.
We expect the visual evidence, documents and data to tell the same story—from the declared source to the received lot and the final shipped product.
- Tagged lots, sampled material and dispatch records should align.
- Containers, seals, export lots and settlement references should remain linked.
- Exceptions should trigger controlled review before the chain continues.
Controlled chain
Traceability architecture.
We create a reference at every custody transfer or transformation so the material identity stays connected from one stage to the next.
ORIGIN & RECEIVING
Supplier / Mine
Verification
Approval
Dispatch
Origin / GPS
Weighbridge / Sample
Receiving lot
PROCESS & SETTLEMENT
Process batch
Blend
Big bag / packing
Container / seal
Export lot
Buyer assay
Supplier settlement
Operating control
Controls and escalation points.
When we see a deviation, we do not treat it as an automatic rejection. We stop the relevant approval, document the variance and resolve the evidence before moving forward.
| Stage | Minimum evidence | Example review trigger |
|---|---|---|
| Counterparty | Identity, role, authority, relationship to mine/source | Identity, ownership or authority inconsistency |
| Origin | Mine, concession, coordinates, evidence of production/stock | Unverifiable origin or material inconsistent with source |
| Transport | Dispatch, vehicle, driver, origin, weight, receiving | Route deviation, weight variance or missing critical record |
| Sampling | Sample ID, lot, date, method, laboratory, custody | Sample not clearly linked to lot or anomalous result |
| Production | Receiving lot → batch → blend → product | Unrecorded mixing or loss of material identity |
| Export | Packing, weight, container, seal, documents | Mismatch between lot, weights, container or seal |
| Settlement | Buyer assay and payment calculation | Unresolved material grade, moisture or mass variance |
Scope
Risk-based framework, not a certification claim.
Legal, regulatory, buyer and due-diligence requirements vary by jurisdiction, mineral and transaction. This framework is designed to support risk-based sourcing and auditable traceability; it does not imply a specific certification or compliance status unless separately documented.
Operating principle
If we cannot sufficiently verify the source, counterparty or lot identity, we keep the transaction under review until the evidence is strong enough for the relevant decision.
