Bulk flows, priced on contained metal and moved under verified provenance.
Strategic and critical minerals underpin electrification, grid infrastructure and defence supply chains, and buyers are under growing pressure to evidence where their material originates. Burlcore Trading applies precious metals documentation discipline to bulk mineral corridors, so industrial buyers receive not only tonnage but a provenance record that survives audit.
Scope of coverage
Corridors include copper cathode and concentrate, and selected critical mineral flows supporting energy transition and industrial manufacturing. Each corridor is opened only after mine licensing, export permitting and counterparty title are independently verified.
Quality and valuation
Concentrates are valued on contained metal after moisture determination and assay, with treatment and refining charges applied per the contract. Sampling protocols follow recognised standards and are witnessed, with retained samples held for umpire analysis if required.
Bulk logistics
Bulk mineral movement introduces port, weighbridge, draft survey and demurrage considerations absent from bullion logistics. Routing, laytime and inspection appointments are agreed before loading, and inspection reports are issued by an independent surveyor rather than by either party.
Regulatory context
Buyers in the European Union increasingly reference the Critical Raw Materials Act and associated due diligence expectations. Corridor documentation is prepared with those obligations in view, so that downstream reporting can draw on records already assembled at origin.

Common questions
How is concentrate priced?+
On contained metal established by assay and moisture determination, with treatment and refining charges deducted according to the contract. Payable percentages and penalty elements for deleterious contents are agreed in advance.
Who appoints the inspector?+
An independent surveyor is appointed to act at load and discharge. Neither buyer nor seller controls the sampling, which is what makes the resulting certificate usable in settlement.
