From the mine to the smelter — with proof.
Responsible sourcing obligations — OECD Due Diligence, EU CSRD, LBMA, RMI — have made chain-of-custody documentation a market access requirement for mineral exporters. OriginTrace maps every extraction site, tracks every unit through processing, and generates the documentation responsible buyers require.

The challenge isn't extraction. It's what happens between the mine and the market.
Tin, tantalum, tungsten, gold, cobalt, and lithium face a growing wall of responsible sourcing requirements. Buyers in electronics, automotive, and battery supply chains now require independently verifiable chain-of-custody documentation before they'll accept delivery.
Artisanal and small-scale mining is where the sourcing risk is highest and the documentation infrastructure is thinnest. OriginTrace registers every extraction site by GPS, verifies every contributing collector's identity, and links every tagged unit back to its verified origin before it enters the aggregation chain.
Responsible sourcing frameworks are multiplying. OECD Due Diligence, EU CSRD, the US Dodd-Frank Act, LBMA Good Delivery, and RMI RMAP all require origin traceability — with different audit standards. OriginTrace tracks the data each framework requires from a single collection record.
From source to payment — every step connected
Every role in the mineral export chain.
Hundreds of contributors. One chain-of-custody record.
You aggregate production from artisanal miners across multiple sites and sell into the formal trading chain. OriginTrace registers every contributing miner and site, tags every unit at source, and generates the chain-of-custody record that formal buyers require.
- GPS extraction site registration with miner KYC
- Unit-level tagging at point of extraction
- Chain-of-custody across aggregation and processing
- Anti-fraud weight validation per collection

Responsible sourcing documentation your buyers can independently verify.
You purchase aggregated mineral production and export to smelters or trading houses in Europe, Asia, or the Gulf. OriginTrace gives you a responsible sourcing score, a complete chain-of-custody pack, and escrow payment settlement when the shipment is confirmed.

Responsible sourcing documentation starts at the mine, not the desk.
We'll show you how OriginTrace builds the chain-of-custody record from first extraction to final export — for your mineral, your buyers, and your markets.
