Reported high grade levels of Gold and PGM are false
Different analytical process = different resuts. They ceased mining for several months for a botched analytical process. Perhaps they should have kept the first assay results under a tight lip until all results where available. My main question is does mass spectroscopy analaysis result in improper results of that magnitude on a regular basis? Might be a few upset investors out there who entered into a position with this company soley based on the reported Gold and PGM levels.

Mass spectrometry rarely results in errors of this magnitude unless it is improperly operated. The complete ionization of the prepared sample feed should result in individual ions being weighed by charge accumulation. Emission or adsorption spectrometry is different and has lots of interfering spectra that need to be properly filtered out. Tons of room for errors here.

geolith: I surmize from your last post that the Mass Spectrometry assays from the initial samples just may be closer to reality than the latest results and to wait for the Mass Spectormetry assays from the Third Lab?

The gold standard is the fire assay. Mass spec is better than, or less likely erroneous from emissions adsorption, but the small sample weight for the spec results cannot compete with the fire assay. All have and continue to yield tremendous errors from inexperienced analysis operators. A reputable lab is your best choice.
