Overview
Concentrates and ores are priced on assay: the payable metal content, less treatment and refining charges, with penalties for elements such as arsenic and bismuth. Sampling and assay at load and discharge are central to every contract.
We confirm the mine or plant, the export permits and the assay history before an offer is presented, and agree the umpire laboratory up front.

Frequently asked questions
How are concentrates priced?
On payable metal content at the relevant exchange price, less treatment and refining charges, with penalties for deleterious elements above agreed limits.

An independent surveyor samples at load or discharge as agreed. Disputes go to an umpire laboratory named in the contract.
Are concentrates shipped in bulk or containers?
Both. Larger lots usually ship in bulk; smaller lots in big bags or lined containers.
