I had suggested to a fellow to have an assay done from any given cat pulled from the pile, he sent the material to American Analytical Labs for the assay.

What puzzled me is that the assay came back showing a presence of gold, so naturally I thought the sample had been contaminated and told him so.

He explained to me how the sample was taken which satisfied me that the sample was not contaminated on his end, he contacted the lab and they did a re-run on the assay from the archived sample. Same results the gold was confirmed.

After giving this some thought I got to thinking that the manufacturer of aftermarket cats are using pregnant liquors from refining e-waste.



Have you ever encountered similar results where gold was present in a cat assay.
