Nice to see the info, but the format still leaves a lot to be desired. As RS states, it's only random checks of the feed and concentrate so there's still no way to calculate total amounts produced per day (especially since no feed rates are given). The numbers supplied look like raw data from the lab, with numbers expressed in more than one form. Don't know why "Total Troy Ounces" is reported, it's only the sum of the weight of gold and silver which are in the previous columns (converted from gm to oz). The two critical numbers are the g/t of Au and Ag in the feed. These are not spectacular, but do look like they are improving, though it's hard to tell with just a few random samples. Another thing to note is that the mill efficiency seems to be improving, with concentration going from ~7.5 (5.1/.68) to 14 to 24 to 32 (29/.9). Also interesting is that the concentrate has a much higher ratio of gold to silver than the feed. Don't know if the silver is not being separated out as well, or maybe the non-native silver (oxides and/or sulfides) is not included in the concentrate assay. Or maybe the mill is being optimized for the removal of gold.
I'm also puzzled as to why RS again refers to the feed as "tailings" from which the gold and silver have already been extracted. It's clear to anyone who has seen the ore that it has not gone through the stamp mills of the time, which would have reduced it to sand sized particles, not the chunks we saw at the SHM. It's also clear from the Idaho Geological Survey report and descriptions that the only true tailings are at the Dewey site (which had a mill). All of the other dumps are unmilled ore for which the only "processing" has been the removal of chunks with visible gold.
