When assayed the ores contained no great amts. of the metals, but through a chemical process have produced huge amts. of metals not a few grams per ton but many ozs. per lb. that simple assay`s can`t find because the lead contained in the fluxes only go after free metal and not after salts. Also PGM`s if present if not inquarted with silver are lost as the PGM`s on the lead burn off the outside of the lead as oxides, or into the slags.
