Patrick - Goerge is exactly correct...To give an idea of the possible density of the Tipuani River valley alluvial sequence - I have running some experiments using sand from an aggregate mine in a similar setting. The density as we have calculated is ~1.6 g/cm3 or 1600 (dry) kg/m3. The average density of the formation is likely somewhere in Mr. Paravicini's report.

If the sand and gravel in the Tipuani valley is of similar density, every cubic meter of meterial removed would have a mass of ~1600kg (this could be as high as maybe 2000 kg/m3, depending on the predominant minerals; for instance, alot of quartz = heavier; feldspars = lighter)

So assuming the higher bulk density, which is the more conservative approach...on a mass removal basis, these pay-streaks would contain 2.15 to 2.8 g-gold/tonne.

for what it's worth...toma
