Minerals Supply-Chain Evidence AI Agent

Keep current the evidence a producer is asked for again and again — chain of custody per shipment, certificate and audit clocks, answers still tied to a source. The certification sits downstream.

What this agent does

Assembles the evidence, not the declaration

In
01

A parcel is despatched, and the despatch, weighbridge and seal records are pulled from supported sources.

02

A lot is blended from two pits, and each contributing lease is carried rather than the template default.

Reason
03

A questionnaire arrives, and each prior answer is re-checked against the source document that supported it.

04

An audit falls due, and the scheme cycle the operation is actually enrolled in is read, not a generic calendar.

05

A certificate nears expiry, and the shipments and answers leaning on it are listed while there is still time.

Decide
06

An origin claim rests on an assay, and the certificate is drawn from the assay copilot rather than restated.

07

A tracing request lands, and the extraction and transport records for that consignment are assembled to a date.

Out
08

A pack is retained as a dated version, beside the records under it and what the answering manager was shown.

09

A write action runs only inside the approval boundaries agreed during implementation.

Product statement

The agent assembles and keeps the evidence current; a named manager answers the customer, and the operator carries every declaration it signs.

Example workflow

One shipment, pit to pack

AgentHuman
1Records receivedDespatch, weighbridge, seal, assay and lease records
2Custody assembledTransfers, blend inputs, certificates and prior answers, each with its named source

4Controls appliedCustody-continuity tests, certificate-currency checks, scheme-scope tests and confidence threshold
No human action required

Stages 1 to 4 run unaided, and nothing is answered at any of them — the agent is assembling evidence, and the manager lane opens at the confidence gate.

5DecisionBranches at the confidence threshold
High confidence

Goes to the commercial manager.

Low confidence

Adds a technical read first.

Manager review

The pack is held with its records, its open gaps and the confidence.

Approve · Amend · Send to technical review

7Outcome evaluatedAmendment distance, open-gap outcomes, audit findings and post-answer corrections
Amendments

Every manager amendment is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required8 items
Certifying the origin of a parcel — a named person does that.
Signing a conformity or due-diligence declaration.
Answering a customer, a scheme or an auditor.
Deciding whether a scheme criterion is met.
Automation boundaryAgent acts unaided
Assemble the chain-of-custody record for a despatched parcel.
Carry each claim with its source, and flag what has none.
Track certificate expiry and the audit cycles entered.
Draft the questionnaire response and hold it for the manager.
Writes run only inside the boundaries agreed at implementation, and never ahead of the manager.
Committing the site to a scheme or its assurance clock.
Warranting origin in a sales or offtake contract.
Withdrawing or correcting a declaration already issued.
Changes to scheme, evidence or approval rules.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Every shipmentFrom the despatch and assay records
03Assembly

Build the custody record

Records already on file are joined into a chain; what is claimed to a customer stays with the manager who answers.

01Approved path

The signer is downstream

Regulation (EU) 2017/821 binds the Union importer, not the mine. What is at stake upstream is market access.

02Human review

One half is not a second product

If you run the shipped commercial and ESG agent, the questionnaire half is a feature of it. What is distinct here is the per-shipment record.

04Build an evidence trail

The shipment, the origin evidence under it and the manager who answered stay on the pack.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

How Nestack evaluates it

Evaluate the assembly workflow — not only the finished pack.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Surface — the answer the customer reads
Depth of coverage ▼
E1Final-output evaluationDid every custody link trace to a document on file?
E2Step-level evaluationDid the agent use the right scheme, cycle and evidence configuration?
E3Tool evaluationDid it read and write the correct shipment and the correct counterparty?

Affected slices

A clean coverage figure can hide one counterparty

A shipment-level evidence-coverage figure can read as complete while a few counterparty and shipment types carry most of the amendments. Nestack reports by slice, not only in total.

Evidence-linked improvement

The loop closes on a new test

A cycle closes when the unanswerable question is a regression case. That suite is what the next pack assembled is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Amendment rate rises for one counterparty slice.

02Diagnose

The eleventh customer asking the same question a different way is read back through the packs until the cause narrows to one.

03Improve

The fix carries a number, and the shipments that forced it travel with it.

04Verify

Nothing goes out until every touched shipment case has passed again.

05Learn

It is kept permanently, and the evidence rules are amended alongside it.

Learn → DetectThe return edge. Detection next time starts from a suite one case longer.

Typical build scope

Twelve workstreams across six weeks

The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, sources, evidence workflow, evaluation, integration, then production validation and handover.

Next step · Mining AI agent

Build the evidence pack before the next questionnaire arrives.

Show us your despatch records, the schemes you are enrolled in and who answers. The certification is carried downstream — by the smelter, the refiner, the listed manufacturer, the importer of record — never by the mine. When an answer that already went out proves unsupported, the manager withdraws it, and the pack shows what they were shown when they gave it.
