Who we source from.

Industrial and mid-tier miners

Companies with a mining licence, a processing plant and a regular export programme. They sell most output under offtake, but release spot cargoes and volumes outside their main contracts.

Processors and refiners

Plants that turn ore into concentrate, hydroxide, cathode or alloy, often buying feed from several mines.

Artisanal and small-scale cooperatives

Registered cooperatives in tin, tantalum, tungsten and gold. We work only with sites that have traceability in place and a legal route to export.

Licensed traders and exporters

Holders of export or dealer licences who aggregate material. We identify the mine of origin behind every lot they offer.

Distillers and aromatic producers

Farms and distilleries producing essential oils, absolutes and resins — the network behind our aromatics catalogue.

4. 04

   Listing

   An anonymised offer is published to verified buyers, with the grade, origin country and volume.

Producers often cannot be named publicly because of offtake agreements or security. Public offers show the grade, origin country, volume and Incoterm, but not the supplier. Identities are shared with a buyer only when both sides agree to an introduction and both have cleared KYC.
