One trail for every gram of Tanzania's gold.

Our flagship proposal, pre-contract: a national mineral-traceability and royalty program we and Black Maple have designed and proposed for Tanzania's artisanal gold sector — not yet built.

A sector that runs on cash and paper.

Roughly 1.5 million Tanzanians mine gold by hand, and close to one in ten depend on the sector. Yet the material moves through buying centres on cash and paper — no chain of custody, no reliable royalty record, and no way for the state to see what left the ground.

For the miner, that means no provenance and a worse price. For the buyer, no proof of origin. For the regulator, royalty owed on a figure no one can reconstruct. Everyone is exposed to the same gap: a record that can't show its work.

One chain of custody — pit to exportaudit trail threads every stage

Pit

Production logged at source — miner, licence, weight, grade.

Buying centre

Purchase, settlement, and movement reconciled against production.

Export

Royalty computed and an export- and audit-ready record produced.

AUDIT TRAIL Every step logged, sourced, and human-verified — running unbroken from the pit to the final royalty figure, attested by Black Maple.

Five capabilities on one platform.

Verified miner identity

Each licensed miner and their production registered to a verifiable identity, so material has an origin from the first gram.

Pit-to-export chain of custody

Production, movement, purchase, and export reconciled into one unbroken, tamper-evident record.

Royalty system of record

Royalty owed computed from the reconciled trail — the figure the authority bills and defends.

Buyer settlement

Transparent purchase and settlement at the buying centre, tied to the same provenance record.

Export & audit reporting

Export- and audit-ready reports, with EITI-grade transparency built in, not bolted on.

Controls first, every result provable.

The same production system behind every Bramley agent — so a national system of record is held to the same gate, review, trail, and attestation discipline as a single certificate.

Pass/fail quality gates

Deterministic checks reconcile production, movement, and export before a figure stands.

Human review

The consequential step — the royalty figure — is signed by a person at the authority.

Audit trail

Every action logged and exportable — the whole chain reconstructable on demand.

Black Maple attestation

An independent firm attests the result — assurance the state doesn't have to take on faith.

Geita first, then national.

Phase 1

Geita

One buying-centre region. Prove the chain of custody and royalty record end to end on real material.

Phase 2

Lake Zone

Extend across the region's buying centres — multi-site reconciliation under one record.

Phase 3

National

A national system of record for the sector — miners, buyers, and the authority on one platform.

“In audit, you learn that software is only worth as much as the record it leaves behind. Bramley is the rare team that builds that way from the first line of code. That's why Black Maple is partnering with them on TrueDig — to give a sector that runs on cash and paper a record miners, buyers, and regulators can all trust. It is designed so we can stand behind the controls, and we don't put our name to a build unless we can.”
