Sure did. We send it all in lots an we get a assay done. (at times I will ask for a 3ed party assay an I will send in a company of my picking.)
The gold amount is not the same by pound. Some years an even some brands would use more or less on there boards.
CPUs even if you have 10 an you assay all 10 (of them all being the same type) they will come out with more or less gold..they dont all ways come out with the same amount in each one.
