Eric, Agreed, some ores don't assay well, but knowledgeable assayers can usually modify techniques to account for many of the difficulties presented by things such as sub-micron particles locked with arsenopyrite, as in Carlin-type deposits. Just realized this is slightly off-topic for this thread, just interesting. Sorry Al, as punishment I'll let someone else pick RMX in the contest for next week, but if it's not taken by late Sunday I'm going to pick it again. regards, john

Eric, Re: Birch Mountain,... Know much about laser ablation followed by inductively coupled plasma mass spectrometry? I think they might be able to identify the presence of Au and PGM's with thin sections (I think thin sections are their main evidence for presence of precious metals right now), then confirm by running the above analysis to get some idea of concentration after running suitable standards. Then they may be able to go back into the field and discover where the hot spots may be. I wonder if fluids coming up from fault zones mobilize the "nano particles". This fluid may then pass by the oil droplets which can concentrate the precious metal particles,... then when erosion takes place you get oxidation/evaporation of the oil which may allow the precious metal particles to further coalesce in a kind of nugget effect. That might explain why panning the streams meets with some success, but sand and limestone samples generally fail. Any thoughts?
