Emertech Trace family  ·  Gold, mine to market

Proof that a bar of African gold can stand up to any buyer, border, or auditor.

EmerTrace Gold is a government-grade chain-of-custody, formalization, risk, revenue, and evidence platform. It connects mine records, licensed trade, measurements, payments, export approvals, and destination-buyer decisions into one auditable trail, with tokenization available as an optional later module.

The information problem

The gold is real. The evidence is missing.

Africa is a leading source of the world's mined gold and, by a wide margin, the largest source of gold that moves without records. The value drains through that gap: lost state revenue, financing that never reaches the miner, and a permanent discount on every honest producer treated with the same suspicion as the smuggler.

Scale and informality

Artisanal and small-scale mining supplies roughly a fifth of global gold and supports about 20 million people worldwide. In Ghana, the small-scale sector alone exported over USD 10 billion in 2025, close to half of national gold exports.

World Gold Council, 2026; Ghana Gold Board, 2025.

Why gold specifically

Gold is fungible, easy to carry, valuable relative to weight, and often traded without complete records. It changes identity through splitting, merging, melting, and refining, so a finished bar may carry no physical link to the material it came from.

ICGLR Regional Certification Mechanism guidance.

What the market now demands

Refiners can be removed from a Good Delivery List for sourcing failures. EU importers carry legal due-diligence duties. Buyers ask not only for purity but for the trail behind it. Provenance has become part of the price.

LBMA Responsible Sourcing; EU Regulation 2017/821.

An honest starting point. A QR code, NFC tag, blockchain record, or AI score can support an evidence claim, but none of them proves origin by itself. EmerTrace Gold is built to record events and evidence, reconcile fine-gold mass, and expose risk, so that an authorized institution, not the software, decides whether a lot is released, held, or certified.
The design center

Five questions, answered for every controlled lot

A credible platform helps an authorized institution answer the same five questions for every lot it controls. Everything in the product exists to build defensible answers to these.

1
Where did the gold come from? Site identity, licence status, geolocation, and source evidence, captured at origin and cross-checked against official registries.
2
Who handled it? Every miner, cooperative, buyer, transporter, lab, refinery, and office as a persistent entity with beneficial-owner records.
3
What was measured and paid? Gross weight, assay purity, fine-gold content, the price calculation, deductions, and the miner's net settlement, with a transparent receipt.
4
What risks were identified? Red flags, unresolved contradictions, and open cases, each with the missing evidence named and an owner assigned.
5
Which authority or buyer can rely on the evidence? A dossier organized by the OECD five steps, with completeness, reconciliation, legal release, and acceptance shown as separate statuses.
Site ID

Source location and operating status.

Entity ID

Any actor in the chain, with ownership.

Lot ID

Physical material and its current quantity.

Evidence ID

The receipt, assay, photo, or record behind an event.

Four identifiers stay persistent across the entire chain, so a claim can always be traced back to the record that supports it.

Chain of custody

One lot, represented as a sequence of events

The physical and institutional chain runs from the mine to the downstream buyer. Tap any stage to see what is captured, where the data comes from, and the risk it defends against. A formal mine has fewer informal handovers; an artisanal chain may pass through several local actors before the first licensed buying point.

Data authenticity

Authenticity is a stack of corroboration, not a database property

An immutable record of a false entry is still false. So every material field carries two separate labels: how it was captured, and whether it has been verified. A typed scale value stays labelled as manual entry even when the operator says it came from a scale.

Capture method, colour-coded across the demo

Manual entry

Typed or transcribed from paper by a person.

Field capture

Geotag, photo, or direct field observation at source.

Instrument feed

Direct read from a scale or assay device.

Official registry

Licence, permit, or record from a government source or API.

Blockchain anchor

Hash, signature, and timestamp preserved on a permissioned ledger.

System-derived

Calculated or reconciled by the platform, such as fine-gold balance.

Verification status, shown next to every field

Corroborated Unreviewed Provisional Disputed Expired / Unavailable

Evidence strength is always visible. A self-declaration, a device reading, an official registry match, and an audited record never look identical. Release requires the relevant controls to pass and any contradictory evidence to be resolved.

Live lot builder

Configure a lot, watch the evidence record respond

Change the country, source type, assay method, corridor, and certificate track. The lot record recomputes fine gold, updates verification status, raises the right risk flags, and tells you whether the export dossier is ready. All data is synthetic and labelled illustrative.

Fine gold grams = gross material grams multiplied by assay purity. The platform keeps gross weight, purity, and fine gold as separate fields and treats fine gold as a conserved quantity for reconciliation.

Field capture, offline first

The field application works without a connection. It queues signed events, shows the last policy version locally, and synchronizes when a trusted network is available. Every field records who captured it, the capture method, and its verification status. Device time, server receipt time, and ledger anchoring time are kept separate.

Device signing does not prove the claimed time or location. An offline event reads as pending synchronization until the server receives it.

Live lot trace

One synthetic lot, end to end, including one real exception

This is the story that shows government value: a lot is created at an artisanal site, moves through buying, transport, and refining, hits a weight and assay mismatch, and is placed on hold. The evidence is preserved, a case is assigned, and a corrected event is recorded. Nothing is silently cleared.

Lot and identities are synthetic and labelled illustrative. Simulated devices, APIs, registry results, and ledger receipts are shown to demonstrate the logic, not to imply a live instrument or government system supplied the data.

The control that matters

Fine-gold mass balance catches the gain that should not exist

At every processing step, total fine-gold input is compared with output, documented loss, and retained residue. An output with more fine gold than all its inputs is the classic signature of unaccounted material entering the chain. The system flags it and holds the lot.

Worked example, at the refinery

Unexplained gain of +10 g. The declared bar shows 1,305 g fine gold against 1,295 g expected. The lot is held. The system checks units and calibration, inspects the sample chain, and opens a case. It does not clear the case by quietly changing a tolerance or inserting an unsupported loss adjustment.

Why this is the right primitive

Gold changes identity during aggregation and refining. Lot genealogy plus fine-gold balance is what survives that change. After a merge, every contributing source and its evidence status is preserved. Material with unresolved origin stays visible in downstream genealogy.

Calling material recycled, melting it, replacing its tag, or routing it through another country does not reset its history or remove a hold.

Field XRF results are treated as provisional unless a laboratory has validated the method and sampling. A discrepancy is a reason to investigate, not proof of criminal conduct.

Country configurations

One technology core, configured per jurisdiction

A pan-African product is a common event, lot, evidence, identity, and risk model, with a country policy layer that decides required fields, approving institution, available certificates, and shareable records. These are deployment archetypes for demo and pilot design, each needing confirmation with the relevant authority.

West Africa

Ghana

Strong central buying model for artisanal gold.

  • GoldBod as sole buyer, assayer, exporter of licensed ASM gold (Act 1140, 2025)
  • Minerals Commission licensing and public procedures
  • Corridor typically to UAE and Switzerland
East Africa

Tanzania

Mixed formal and small-scale with buying centres.

  • Mining Commission and the minerals market information system
  • Designated mineral buying centres and export desks
  • Different national configuration from Ghana for comparison
Great Lakes

DRC / regional

Strongest regional chain-of-custody demonstration.

  • CEEC certification and ICGLR Regional Certification Mechanism
  • Heaviest conflict-sensitivity and due-diligence stakes
  • Best case for cross-border chain of custody

Optional later module

Tokenization, as an option, once the physical corridor is proven

Token issuance sits outside the initial government pilot. When a physical-gold corridor is working, the same verified genealogy can extend into an allocated inventory record, and from there into a regulated tokenized product. Provenance is what makes such a token investable, but provenance alone establishes neither full backing nor legal redeemability.

Honest note: a custody confirmation and an on-chain record are separate evidence. A regulated token needs explicit reserve and liability reconciliation, allocation controls against duplicate claims, minting and redemption records, and enforceable ownership. Issuance and reserve law require a separate workstream. This module is not required to demonstrate national gold traceability.

Honest guardrails

What this platform does not claim

Stating the limits is the credential. Sophisticated buyers and funders have watched overclaiming traceability projects fail.

!
A ledger secures records, not truth. An immutable record of a false entry is still false. Authenticity is engineered through instruments, corroboration, and reconciliation, never asserted by a database.
!
No tool proves origin alone. QR, NFC, blockchain, and AI scores support an evidence claim. Origin is established by capture method, actor authority, measurement controls, and independent checks.
!
People stay in the decision loop. AI flags patterns and missing evidence. It never makes an autonomous origin, certification, sanctions, or release decision.
!
EmerTech supplies technology, not verdicts. Government owns policy, data governance, and release or certification authority. Laboratories, buyers, and auditors keep their own decisions.
!
Traceability is not enforcement. A platform makes records visible, connected, and auditable. It cannot by itself eliminate smuggling, corruption, or environmental harm without incentives, safe reporting, and public capacity.
!
Not a market-size number. Historical smuggling estimates are context, not a revenue-recovery target or software market size. A pilot establishes its own baseline from official records and field work.
Recommended path

A gold-only design and a synthetic demo, then one real corridor

The first pilot tests the operating model as much as the software. The highest risk is not whether a screen can be built, but whether field actors, buyers, inspectors, labs, and authorities create records that are useful, safe, and accepted.

1
Select one pilot authority and one corridor. Ghana and Tanzania offer different national configurations; a Great Lakes or DRC configuration gives the strongest regional chain-of-custody demonstration.
2
Create the country legal and data matrix before finalizing screens or mandatory fields.
3
Agree the governance model: data controller, competent certificate authority, buyer and refiner participants, auditor, grievance owner, and escalation paths.
4
Build the common event and lot model with a versioned policy engine, then one country pack and one buyer or regional evidence pack.
5
Demonstrate one synthetic lot end to end, including an offline capture, a measurement discrepancy, a risk case, a corrected event, and a final evidence pack.
6
Run a controlled field pilot, measure data quality and user burden, and revise before adding countries or cross-border exchange. Defer token issuance, automatic certification, and full pan-African deployment.
Why EmerTech. EmerTech has issued more than 15 million blockchain traceability QR codes across live supply chains, has been cash-positive for two consecutive years, and already builds allocated, tokenized reserves on public infrastructure. Traceability, compliance, and tokenization are the three lines that gold sits exactly across. Specialist partners are still needed for calibrated weighing and sampling, laboratory assurance, mine inspection, mercury practice, AML and beneficial ownership, customs, cybersecurity, data protection, and independent audit. A technology vendor cannot supply those authorities.
