Very simple Zeev, the exchanges won't let non -SFA stuff be released out there in Canada. IMO. IPM is Canadian by Rules as well as Nasdaq reporting for the last few months.

The SEM will analyse individual atoms.

I mean the scanning tunneling type that was pioneered with a tungsten
tip needle

I think it would find the nano-clusters if they are there.

Te will interfere with the any assay, fire or wet chemical. As arsensic, it is a co-precipitant. Gold "arsenides" are also expected to hide gold from fire assay. Haultain in 1934 says that he was able to control for the Te with adding enough silica to reduce the per cent telluride to 10%. He was convinced that the Kirkland Lake ores that he woked with that had 15% of their gold in Telluride were satisfactorily assayed.

I am of the belief that this is not yet written in stone.

If a substance is as good a scavenger of gold as any collector then one is had pressed to find a mechanism to oxidize it in preference to its amalgam. Some people believe that niter will do it. I think there may be other ways to do it.

The colorado assyers started with a cold furnace. I have a clue about cold methods.

Zeev,
XRF and neutron activation are other techniques which could be used. They are readily available and would detect platinum group metals, even if they are present as nano-clusters, or even in solid solution. The small sample size used in these methods would not be a problem - there won't be any nugget effects with 10 Angstrom particles!
