Independent third-party assay and inspection records for the non-ferrous trade — the certified composition of physical cargo as it actually moved, not as anyone reported it. Per consignment: sampled copper, zinc, nickel, lead and gold concentrate along with copper cathode, weight and moisture basis, copper grade, and the impurity/sulfur panel (sulfur and iron content, plus penalty elements such as arsenic, mercury and lead), delivered against international and national standards from pit to port to market. Alongside assay sits stock-take and physical-verification data on smelter and warehouse inventories, due-diligence findings, and an expanding embedded-emissions/CBAM assurance layer. The latent asset is the cross-counterparty panel: no single miner can see its own concentrate quality against everyone else's, but the inspector holds the whole distribution.
